Methods for testing data quality, scaling assumptions, and reliability: the IQOLA Project approach. International Quality of Life Assessment

Translation and cross-cultural adaptation of the Kidney Transplant Questionnaire 25 to Greek

BACKGROUND

Kidney transplantation leads to continuous improvement in the survival rates of kidney transplant recipients (KTRs) and has been established as the treatment of choice for patients with end-stage kidney disease. Health-related quality of life (HRQoL) has become an important outcome measure. It is highly important to develop reliable methods to evaluate HRQoL with disease-specific questionnaires.

AIM

To translate the disease-specific instrument Kidney Transplant Questionnaire 25 (KTQ-25) to the Greek language and perform a cross-cultural adaptation.

METHODS

The translation and adaptation of the original English version of the KTQ-25 to the Greek language were performed based on the International Quality of Life Assessment.

RESULTS

Eighty-four KTRs (59 males; mean age 53.5 ± 10.7 years; mean estimated glomerular filtration rate 47.7 ± 15.1 mL/min/1.73 m²; mean transplant vintage 100.5 ± 83.2 months) completed the Greek version of the KTQ-25 and the 36-item Short-Form Health Survey, and the results were used to evaluate the reliability of the Greek KTQ-25. The Cronbach alpha coefficients for all the KTQ-25 dimensions were satisfactory (physical symptoms = 0.639, fatigue = 0.856, uncertainty/fear = 0.661, appearance = 0.593, emotions = 0.718, total score = 0.708). The statistically significant correlation coefficients among the KTQ-25 dimensions ranged from 0.226 to 0.644. The correlation coefficients of the KTQ-25 dimensions with the SF-36 physical component summary (PCS) ranged from 0.196 to 0.550; the correlation coefficients of the KTQ-25 with the SF-36 mental component summary (MCS) ranged from 0.260 to 0.655; and the correlation coefficients of the KTQ-25 with the total scores with the SF-36 PCS and MCS were 0.455 and 0.613, respectively.

CONCLUSION

According to the findings, the Greek version of the KTQ-25 is valid and reliable for administration among kidney transplant patients in Greece.

Measuring Vocal Fatigability in Teachers: The Vocal Fatigability Scale for Teachers (VFS-T)

OBJECTIVES

This study focuses on the distinction between vocal fatigability and vocal fatigue (VF), highlighting the importance of vocal fatigability when assessing teachers' quality of life. Vocal fatigability is more critical for quality of life than performance or perceived VF because it considers the accumulation and chronicity of fatigue over isolated tasks. The objectives are to develop and validate the Vocal Fatigability Scale for Teachers (VFS-T), to assess teachers' levels of vocal fatigability, and to analyze variations based on personal and occupational traits. The VFS-T construct encompasses items related to vocal sensations and performance, their connection to accumulated demanding vocal activity, descriptions of recovery strategies, necessary rest periods, and the impact of VF on daily activities.

STUDY DESIGN

A single cross-sectional study with an ex post facto design was conducted.

METHODS

The sample consisted of 184 active teachers with various vocal conditions. They completed the VFS-T questionnaire, provided personal and occupational data, and completed the VHI-10 questionnaire. The data collected were analyzed for item refinement, internal structure, reliability, validity, diagnostic capacity, cutoff values, and group differences.

RESULTS

The item refinement and internal structure analysis revealed a scale comprising 17 items grouped into two factors. The VFS-T shows good reliability and validity, with cutoffs at <15 for no fatigability, 15-27 for moderate fatigability, and >28 for high fatigability. Most teachers fall into the moderate fatigability range, with 72% experiencing vocal fatigability.

CONCLUSIONS

The VFS-T is a reliable tool for detecting vocal fatigability in teachers. This scale focuses on the construct of vocal fatigability, which is related to chronicity of VF and limitations in daily activities in teachers.

Cross-cultural adaptation and validation of the Italian version of the Western Ontario Rotator Cuff (WORC) index

The aim of the study was to accomplish translation, cross-cultural adaptation and validation of the Western Ontario Rotator Cuff (WORC) Index questionnaire for its use in Italy. The WORC original version was translated and cross-culturally adapted into Italian. Subsequently, it was administered to a population of 60 patients suffering from rotator cuff disease to evaluate the validity and reliability of the Italian version. The content validity evaluated the correlation between questions and total score of each domain through Pearson's correlation coefficient. The construct validity was similarly assessed through Pearson's correlation coefficient by testing the correlation between the Italian WORC and the Italian version of the Disability of the Arm, Shoulder and Hand (DASH) questionnaire. Reliability was assessed using two methods: internal consistency by calculating the Cronbach's alpha coefficient for each domain; and test-retest by means of the intraclass correlation coefficient (ICC). The translation and cross-cultural adaptation of the Italian version did not reveal any major problems. No significant floor or ceiling effects were found. All the questions were linearly related to the concept expressed by the domain of belonging. Overall correlation with the DASH score was 0.75. Internal consistency was very high overall (α = 0.93) as well as reliability (overall ICC = 0.87). The Italian version of the WORC questionnaire is a valid and reproducible measuring instrument and can be considered a valid tool for the evaluation of the effectiveness of a treatment in terms of quality of life, in Italian patients affected by rotator cuff diseases.Level of evidence Diagnostic study, level II.

Individual Earthquake Resilience Scale: Psychometric Properties of the Turkish Version

INTRODUCTION

The Individual Earthquake Resilience Scale was developed with the aim of measuring individual resilience in the context of earthquake disasters. The purpose of this study was to adapt the Individual Earthquake Resilience Scale into Turkish and examine its psychometric properties.

METHODS

A total of 419 adult individuals (65.2% females, median age = 43.35) participated in the study. The psychometric properties of the scale were examined in terms of content validity, face validity, construct validity, criterion-related validity, and reliability. Translation and back-translation processes were conducted.

RESULTS

Confirmatory factor analyses revealed that the scale has a 4-factor structure. In terms of criterion-related validity, a positive relationship was found between Individual Earthquake Resilience and the Short Psychological Resilience Scale. The reliability of the scale was assessed using Cronbach's alpha coefficient. The total scale had a Cronbach's alpha score of 0.892. The Individual Earthquake Resilience Questionnaire subscales had Cronbach's alpha scores of 0.620, 0.817, 0.776, and 0.692, respectively.

DISCUSSION

The study confirmed that the 4-factor structure of the Individual Earthquake Resilience Scale met the required standards for validity and reliability at an acceptable level. This validates its use in assessing individual resilience within the context of earthquakes in a Turkish-speaking population.

Mini-ACE: Validation Study Among Older People in Long-Term Care

Background

The Mini-Addenbrooke's Cognitive Examination (M-ACE) is a valid and reliable tool that accurately differentiates various types of cognitive impairment from Normal-cognition assessed in multiple settings. However, its validity among older individuals in long-term care (LTC) was not yet established. Therefore, we sought to assess the Portuguese M-ACE's validity, reliability, and accuracy in detecting cognitive impairment no-dementia (CIND) in LTC users.

Methods

A comprehensive assessment was performed on 196 LTC Portuguese users aged ≥ 60 years, among whom 71 had Normal-cognition, and 125 had CIND.

Results

The M-ACE was found to be reliable (McDonald's ω = .86, Cronbach's α = .85) and consistent over time (r = .72; ICC = .83) and between raters (k = .92). Strong correlations with related measures supported construct validity (both r = .67). The M-ACE accurately distinguished CIND from Normal-cognition with a cut-off of 17 points (AUC = 0.81, Sensitivity = 81.7%, Specificity = 74.4%).

Conclusion

Our findings suggest that the Portuguese M-ACE is a valid and reliable cognitive assessment tool for LTC users, allowing for accurate differentiation between CIND and Normal-cognition. Thus, the M-ACE's use could contribute to the early detection and intervention of cognitive disorders, especially among older adults in LTC.

Emotion dysregulation in older people: validity and reliability of an 8-item version of the Difficulties in Emotion Regulation Scale

OBJECTIVES

The abbreviated 16-item version of the Difficulties with Emotion Regulation Scale (DERS-16) is widely used to assess individuals' perceived challenges in regulating their emotions, a central aspect of psychological symptoms commonly experienced in old age. However, its psychometric properties have yet to be tested in this population. Furthermore, a shorter version of the DERS-16 could further minimize the assessment burden on older individuals. Thus, we aimed to test the DERS-16's psychometric performance and determine if any items were redundant to develop a psychometrically sound shorter version.

METHODS

We enrolled 302 Portuguese older adults (Mage = 75.22; SD = 8.99 years) in a cross-sectional study.

RESULTS

Exploratory factor analyses indicated a one-factor structure and a four-factor solution with eight items (69.3%-81.9% of the variance observed). The four-factor-8-item solution presented an interpretable structure and demonstrated good reliability values (> 0.70) and construct validity with the Twenty-Item Toronto Alexithymia Scale, Eight-Item Geriatric Depression Scale, and Geriatric Anxiety Inventory (r = 0.66, 0.40, 0.52; p < 0.001).

CONCLUSION

The robust psychometric properties of DERS-8 make it a valuable tool for clinical and longitudinal studies, facilitating targeted interventions in older adults and allowing for precise emotion dysregulation screening.

Cross-cultural adaptation and validation of the Mental Health Quality of Life (MHQoL) questionnaire in a Chinese-speaking population with chronic musculoskeletal pain

BACKGROUND

The Mental Health Quality of Life (MHQoL) questionnaire is concise and suitable for rapid assessment of CMP (chronic musculoskeletal pain) patients in primary care. However, there is a lack of Chinese versions of the MHQoL.

OBJECTIVE

To cross-culturally translate the MHQoL into Chinese and to assess its psychometric properties in Chinese-speaking patients with CMP.

METHODS

The MHQoL was translated into Chinese according to the International Guidelines for the Cross-Cultural Adaptation of Self-Report Measures. 171 CMP patients were recruited to receive the Chinese versions of the MHQoL, SF-36, and HADS tests, and the MHQoL was retested seven days later.

RESULT

The Chinese version of MHQoL had good retest reliability (MHQoL-7D: ICC = 0.971; MHQoL-VAS: ICC = 0.988) and internal consistency (Cronbach's alpha = 0.829). It showed a moderate correlation with the SF-36 total score (r=-0.509); the MHQoL-VAS moderately correlated with the Hospital Anxiety Depression Scale (r=-0.548). The MHQoL-7D showed no correlations with the SF-36's PF (r=-0.083) and BP (r=-0.170), weak correlations with RP (r=-0.284), RE (r=-0.298), and SF (r=-0.380), and moderate-to-strong correlations with GH (r=-0.638), VT (r=-0.480), and MH (r=-0.632).

CONCLUSION

The Chinese version of the MHQoL can be used in clinical practice and research in Chinese-speaking CMP patients.

Psychometric properties and factor structure of the brief Wisconsin Inventory of Smoking Dependence Motives among Spanish smokers from the general population

INTRODUCTION

The brief version of the Wisconsin Inventory of Smoking Dependence Motives (B-WISDM) is a well-established instrument to measure the multidimensional nature of nicotine dependence. However, no previous research has assessed its psychometric properties in the Spanish context. The aim of the present study was to analyze the factor structure and measurement invariance across gender of this instrument among Spanish smokers from the general population.

METHODS

This cross-sectional study assessed 480 smokers through an online questionnaire including information on tobacco use and several nicotine dependence measures. Confirmatory Factor Analysis was used to assess the factorial structure of the Spanish B-WISDM, its internal consistency, measurement invariance across gender and convergent validity with the Fagerström Test for Nicotine Dependence (FTND) and the Glover-Nilsson Smoking Behavioral Questionnaire (GN-SBQ) scores.

RESULTS

Results indicate that the eleven correlated factors solution had a better fit when compared to the other tested models (two correlated factors and two second-order factors with eleven first-order correlated factors solution), remaining such structure invariant across gender. Internal consistency of the scale was high (α = 0.950; dimension α values ranged between 0.657 and 0.921). Overall scores and dimensions of the scale significantly and positively correlated with other nicotine dependence measures (except for Social/Environmental Goads and FTND).

CONCLUSIONS

This is the first version of the B-WISDM validated to assess nicotine dependence with a multidimensional perspective within the Spanish culture. Results show adequate psychometric properties regarding its factor structure and measurement invariance across gender, supporting its utility to evaluate the motives driving tobacco use among Spanish smokers from the general population.

Translation, cross-cultural adaptation and measurement proprieties of the German version of the Allodynia Symptom Checklist (ASC-12)

BACKGROUND

Cutaneous allodynia is highly prevalent among migraineurs and is associated with a poor prognosis. The Allodynia Symptom Checklist (ASC-12) is a comprehensive questionnaire to identify the presence and severity of allodynia. Our aim was to translate and adapt the ASC-12 to German and evaluate its measurement properties.

METHODS

Following the COSMIN guidelines, 80 migraine patients were enrolled in the study to evaluate the stages of translation (n=30) and measurement propriety assessment (n=50), respectively. After reaching a final version, the German ASC-12 was assessed for structural validity, internal consistency, test-retest reliability, construct validity and absolute agreement, using mechanical and thermal pain thresholds as reference method.

RESULTS

The German version of the ASC-12 presented an adequate structural validity compatible with the original version of the questionnaire. Its internal consistency ranged from 0.70 to 0.80 considering the total score and the thermic, static and dynamic mechanic subdomains. The total score presented excellent reliability (ICC: 0.85) with a standard error of measurement of 1.15 points and smallest detectable change of 3.40 points. ASC-12 total scores were correlated with headache intensity (r=0.38, p=0.004), headache disability (r=0.37, p=0.004) and cold pain thresholds (r=0.28, p=0.025). The thermic allodynia ASC-12 scores were correlated with cold (r=0.36, p=0.005) and heat (r=-0.30, p=0.010) pain thresholds, while the static mechanical allodynia ASC-12 scores correlated with mechanical pain threshold (r=0.29, p=0.019) and with mechanical pain sensitivity (r=0.24 to 0.28, p< 0.045). Despite no significant bias between methods, quantitative sensory testing (QST) results and ASC-12 scores tend to disagree.

CONCLUSION

The German version of the ASC-12 is available for research and clinical settings and presented adequate measurement proprieties, as the original version. Despite the correlation between the ASC-12 and QST, one method cannot be replaced by the other.

Psychometric validation of the Kolcaba General Comfort Questionnaire in critically ill patients

BACKGROUND

There is a lack of validated tools to measure comfort in critically ill patients.

OBJECTIVE

The objective of this study was to evaluate the psychometric properties of the General Comfort Questionnaire (GCQ) in patients admitted to intensive care units (ICUs).

METHODOLOGY

A total of 580 patients were recruited, randomising the sample into two homogeneous subgroups of 290 patients for exploratory factor analysis and confirmatory factor analysis, respectively. The GCQ was used to assess patient comfort. Reliability, structural validity, and criterion validity were analysed.

RESULTS

The final version included 28 of the 48 items from the original version of the GCQ. This tool was named the Comfort Questionnaire (CQ)-ICU, maintaining all types and contexts of the Kolcaba theory. The resulting factorial structure included seven factors: psychological context, need for information, physical context, sociocultural context, emotional support, spirituality, and environmental context. A Kaiser-Meyer-Olkin value of 0.785 was obtained, with Bartlett's sphericity test (0.000) being significant, and the total variance explained was 49.750%. The Cronbach's alpha was 0.807, with subscale values ranging from 0.788 to 0.418. Regarding convergent validity, high positive correlations were obtained between the factors and the GCQ score, the CQ-ICU score, and the criterion item GCQ31: "I am content". In terms of divergent validity, correlations were low with the APACHE II scale and with the NRS-O except for physical context (-0.267).

CONCLUSION

The Spanish version of the CQ-ICU is a valid and reliable tool to assess comfort in an ICU population 24 h after admission. Although the resulting multidimensional structure does not replicate the Kolcaba Comfort Model, all types and contexts of the Kolcaba theory are included. Therefore, this tool enables an individualised and holistic evaluation of comfort needs.

Reliability of FUNDES-Child-SE - measuring participation and independence of children and youths with disabilities

BACKGROUND

There is a need for an instrument to measure participation and independence in children with disabilities. FUNDES-Child-SE has its origin in the participation questionnaire Child and Adolescent Scale of Participation.

AIMS

Test the psychometric properties of internal consistency and test-retest reliability.

MATERIAL AND METHODS

This cross-sectional study included caregivers of 163 children with disability aged 6-18 years, 59 of whom were also included in the test-retest study. Descriptive statistics were used to evaluate the proportions of valid ratings. Internal consistency and test-retest reliability were tested through Cronbach's alpha and the intra-class correlation coefficient.

RESULTS

The amount of not relevant/not applicable ratings was substantial but varied between items and subdomains. Internal consistency was acceptable (0.8-0.95), and the test-retest was marginal to excellent (0.73-0.95).

CONCLUSIONS

The reliability together with the content validity support the use of the FUNDES-Child-SE to measure participation and independence in children with disabilities. However, results should be interpreted with caution due to the small sample size and possible selection bias. Modifications to reduce the not relevant/not applicable responses should be investigated together with the instrument's responsiveness.

SIGNIFICANCE

FUNDES-Child-SE can be used to facilitate a discussion of participation and independence and to plan interventions in a habilitation setting.

Development and validity of the expectations of physiotherapists questionnaire on practice management software

Background

Despite the growing trend in the use of digital technologies in physiotherapy, the overall adoption of both, practice management software (PMS) and electronic health records in physiotherapy clinics has been low and slow over time. In order to learn what factors determine the adoption of these technologies by physiotherapists, there is a need to examine the expectations of physiotherapists (EPs) on specific software attributes. The main aims of this study were to develop a questionnaire to measure and describe the EPs towards PMS. The knowledge of these EPs will be useful to guide PMS design in order to improve physiotherapists' satisfaction.

Methods

Instrument development study with validity and reliability testing. The development of this questionnaire was conducted in three phases: identification of attributes to be explored, development of the items, pilot study, and psychometric testing. The questionnaire was distributed to chartered physiotherapists. A total of 272 participants completed the questionnaire.

Results

A series of analysis were conducted to assess item reduction, factor structure of the questionnaire and metric properties of multi-item scales. From the initial 43 attributes, the final version of the questionnaire consisted of 26 items on EPs, grouped in nine scales and two areas (clinical care and administrative activities). As a result, all scores had strong item-scale correlations, excellent item scaling success, and good internal consistency (Cronbach alpha coefficients of >.7). Our study also showed that current EPs were high towards most of the items, only two scales concentrated most of the attributes with the least expectations (monitoring quality of care and digital health interventions). Our study included physiotherapists with and without experience with PMS, and it showed that both groups had a similar pattern of expectations. Our study provides a valuable questionnaire of EP on PMS attributes for clinical care and administrative activities and shows a detailed development process.

Knowledge and Perception of the Use of AI and its Implementation in the Field of Radiology: Cross-Sectional Study

BACKGROUND

Artificial Intelligence (AI) has been developing for decades, but in recent years its use in the field of health care has experienced an exponential increase. Currently, there is little doubt that these tools have transformed clinical practice. Therefore, it is important to know how the population perceives its implementation to be able to propose strategies for acceptance and implementation and to improve or prevent problems arising from future applications.

OBJECTIVE

This study aims to describe the population's perception and knowledge of the use of AI as a health support tool and its application to radiology through a validated questionnaire, in order to develop strategies aimed at increasing acceptance of AI use, reducing possible resistance to change and identifying possible sociodemographic factors related to perception and knowledge.

METHODS

A cross-sectional observational study was conducted using an anonymous and voluntarily validated questionnaire aimed at the entire population of Catalonia aged 18 years or older. The survey addresses 4 dimensions defined to describe users' perception of the use of AI in radiology, (1) "distrust and accountability," (2) "personal interaction," (3) "efficiency," and (4) "being informed," all with questions in a Likert scale format. Results closer to 5 refer to a negative perception of the use of AI, while results closer to 1 express a positive perception. Univariate and bivariate analyses were performed to assess possible associations between the 4 dimensions and sociodemographic characteristics.

RESULTS

A total of 379 users responded to the survey, with an average age of 43.9 (SD 17.52) years and 59.8% (n=226) of them identified as female. In addition, 89.8% (n=335) of respondents indicated that they understood the concept of AI. Of the 4 dimensions analyzed, "distrust and accountability" obtained a mean score of 3.37 (SD 0.53), "personal interaction" obtained a mean score of 4.37 (SD 0.60), "efficiency" obtained a mean score of 3.06 (SD 0.73) and "being informed" obtained a mean score of 3.67 (SD 0.57). In relation to the "distrust and accountability" dimension, women, people older than 65 years, the group with university studies, and the population that indicated not understanding the AI concept had significantly more distrust in the use of AI. On the dimension of "being informed," it was observed that the group with university studies rated access to information more positively and those who indicated not understanding the concept of AI rated it more negatively.

CONCLUSIONS

The majority of the sample investigated reported being familiar with the concept of AI, with varying degrees of acceptance of its implementation in radiology. It is clear that the most conflictive dimension is "personal interaction," whereas "efficiency" is where there is the greatest acceptance, being the dimension in which there are the best expectations for the implementation of AI in radiology.

Translation, cultural adaptation, and psychometric testing of the Supportive care needs survey for partners and caregivers for Swedish family members of persons diagnosed with colorectal cancer

BACKGROUND

Colorectal cancer is the third most common cancer diagnosis globally and is increasing in both incidence and prevalence. Despite evidence showing that family members of persons diagnosed with cancer have supportive care needs, no validated questionnaire measuring the needs of family members of persons diagnosed with CRC exists in Swedish. Thus, the objective of the present study was to translate, culturally adapt, and evaluate the psychometric properties the Supportive Care Needs Survey - Partners and Caregivers 45.

METHODS

The translation and cultural adaptation followed a systematic yet iterative process. Firstly, the questionnaire was translated using a forward-backward approach. Secondly, face and content validity and comprehensibility were evaluated by two expert panels of colorectal cancer specialist nurses and family members, respectively. Lastly, the psychometric properties, validity, and reliability of the translated questionnaire were evaluated among 45 Swedish family members of persons diagnosed with colorectal cancer.

RESULTS

The face, content, and construct validity of the translated questionnaire were evaluated as satisfying. Moreover, psychometric evaluations showed high data quality and satisfactory internal consistency. However, the results also revealed unsolved issues regarding relevance, targeting, and internal consistency, as well as a probable scaling failure.

CONCLUSION

The translated and adapted questionnaire can be used to identify family members unmet needs of support throughout the colorectal cancer trajectory. The questionnaire showed promising validity and reliability in the target population. However, it needs to be further evaluated in a larger sample, preferably involving factor analysis and stability over time.

Psychometric properties of the Korean version of the oncofertility barriers scales among nurses: A methodological study

Objective

This study aimed to examine the psychometric properties of the Korean version of the Oncofertility Barrier Scale (K-OBS).

Methods

This methodological study investigated the validity and reliability of the K-OBS for measuring barriers to oncofertility care among nurses. A total of 270 nurses who had experience in rendering nursing care to cancer survivors were recruited, and the instrument was translated, assessed for content validity, and tested using a preliminary survey. Construct validity was established through explanatory factor analysis. Convergent validity and discriminant validity were analyzed using a multitrait-multimethod (MTMM) matrix. Reliability was assessed using Cronbach's alpha and McDonald's omega.

Results

The K-OBS demonstrated satisfactory validity and reliability, with seven factors, including 27 items explaining 60.42% of the total variance, a Cronbach's alpha of 0.86, and a McDonald's omega of 0.83. The seven factors were labeled, "Lack of information and education" (8 items), "Rigid thinking toward oncofertility care" (5 items), "Cancer patient stereotypes" (4 items), "Insufficient support" (4 items), "Desire for fertility preservation" (2 items), "Interrupted oncofertility care" (2 items), and "Fertility risk" (2 items).

Conclusions

The results of this study indicate that the K-OBS may be a suitable instrument with acceptable validity and reliability for evaluating barriers to oncofertility among Korean nurses. This instrument can be used to identify obstacles that make oncofertility care difficult, thereby contributing to new insights for improving the future quality of oncofertility care in Korea.

Further development and evaluation of a questionnaire targeting person-centred outpatient care for persons with long-term conditions

AIM

To further develop the Person-Centred Care instrument for outpatient care (PCCoc), evaluate its user-friendliness and content validity, and to explore its basic psychometric properties in various outpatient settings for adults with long-term conditions.

BACKGROUND

Person-centred care (PCC) has been identified as a key factor to provide high-quality care. However, there is still a lack of instruments that are based on a clearly defined framework for PCC for persons with long-term conditions in an outpatient context. The PCCoc is a patient-reported experience measure under development aiming to fill this gap.

METHODS

First, the 35-item PCCoc was reviewed and further developed in collaboration with a user-council. Second, the revised 36-item PCCoc was tested among persons receiving outpatient care for various long-term conditions. A total of 179 persons with long-term conditions from four different specialties participated in the study. User-friendliness and content validity were assessed through structured interviews and relevance ratings of each item. Content validity index (CVI) for individual items (I-CVI) and for the overall scale (S-CVI) were calculated, and basic psychometric properties of the PCCoc using classical test theory were explored.

RESULTS

It took a median of 8 min for participants to complete the PCCoc. The majority found items easy to understand, response categories distinct and that no important areas were missing. Results from the CVI analyses suggested that participants found the content of the PCCoc relevant (I-CVI range 0.82-1, S-CVI = 0.95). All psychometric properties examined were satisfactory (e.g., item-total correlations, 0.45-0.75; Cronbach's alpha, 0.96; test-retest stability, 0.83).

CONCLUSION

The PCCoc was considered user-friendly and relevant by the intended users, and its psychometric properties were satisfactory. This implies that the PCCoc can be a valuable instrument for evaluating and developing PCC in outpatient care for persons with long-term conditions. However, further studies of the PCCoc are needed to establish its measurement properties in various outpatient settings.

Are Patient-Reported Outcome Measures for Distal Radius Fractures Validated for Spanish and Culture? A Systematic Review

PURPOSE

Patient-reported outcome measures (PROMs) are used commonly to assess function to direct treatment and evaluate outcomes for patients with distal radius fractures. Most PROMs have been developed and validated in English with minimal report of the demographics of patients studied. The validity of applying these PROMs among Spanish-speaking patients is unknown. The purpose of this study was to evaluate the quality and psychometric properties of Spanish-language adaptations of PROMs for distal radius fractures.

METHODS

We conducted a systematic review to identify published studies of adaptations of Spanish-language PROMs evaluating patients with distal radius fractures. We evaluated the methodologic quality of the adaptation and validation using Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures, Quality Criteria for Psychometric Properties of Health Status Questionnaire, and the Consensus-based Standards for the Selection of Health Measurement Instruments Checklist for Cross-Cultural Validity. The level of evidence was evaluated based upon prior methodology.

RESULTS

Five instruments reported in eight studies were included: the Patient-Rated Wrist Evaluation (PRWE), Disability of Arm Shoulder and Hand, Upper Limb Functional Index, Lawton Instrumental Activities of Daily Living Scale, and Short Musculoskeletal Function Assessment. The PRWE was the most frequently included PROM. No study followed all six processes for adaptation or assessed all measurement properties. No study demonstrated the completion of more than eight of the 14 aspects of cross-cultural validity. The PRWE had moderate evidence to support half of the domains of measurement properties evaluating the level of evidence.

CONCLUSIONS

None of the five instruments identified received a good rating on all three checklists. Only the PWRE demonstrated moderate evidence on half of the measurement domains.

CLINICAL RELEVANCE

Given the lack of strong evidence to support the quality of these instruments, we recommend adaptation and testing of PROMs for this population before use. Currently, PROMs in Spanish-speaking patients should be used with caution so as not to perpetuate health care disparities.

Development and validation of the health literacy environment scale for Chinese hospitals from patients' perspective

Introduction

While the research on improving individual health literacy by promoting individual skills and abilities is increasing, less attention has been paid to the complexities of the healthcare environment that may influence patients' ability to access, understand, and apply health information and health services to make health decisions. This study aimed to develop and validate a Health Literacy Environment Scale (HLES) that is suitable for Chinese culture.

Methods

This study was conducted in two phases. First, using the Person-Centered Care (PCC) framework as a theoretical framework, initial items were developed by using the existing health literacy environment (HLE) related measurement tools, literature review, qualitative interviews, and the researcher's clinical experience. Second, scale development was based on two rounds of Delphi expert consultation and a pre-test conducted with 20 hospitalized patients. Using 697 hospitalized patients from three sample hospitals, the initial scale was developed after item screening and its reliability and validity were evaluated.

Results

The HLES comprised 30 items classified into three dimensions as follows: interpersonal (11 items), clinical (9 items), and structural (10 items) dimensions. The Cronbach's α coefficient of the HLES was 0.960 and the intra-class correlation coefficient was 0.844. The confirmatory factor analysis verified the three-factor model after allowing for the correlation of five pairs of error terms. The goodness-of-fit indices signified a good fit for the model (χ²/df = 2.766, RMSEA = 0.069, RMR = 0.053, CFI = 0.902, IFI = 0.903, TLI = 0.893, GFI = 0.826, PNFI = 0.781, PCFI = 0.823, PGFI = 0.705). The item-content validity index ranged from 0.91 to 1.00, and the scale-content validity index was 0.90.

Conclusion

The HLES had good reliability and validity and provides a patient perspective tool for evaluating HLE and a new perspective for improving health literacy in China. That is, healthcare organizations make it easier for patients to access, understand, and use health information and service. Further studies about the validity and reliability of HLE should include other districts and different tiers or types of healthcare organizations.

Obstructive Sleep Apnea in Adults with Treacher Collins Syndrome is Related with Altered Anthropometric Measurements, Increased Blood Pressure and Impaired Quality of Life

Objectives  This study aimed at evaluating the risk for obstructive sleep apnea (OSA) and its frequency in adults with Treacher Collins syndrome (TCS). The association of OSA with excessive daytime sleepiness (EDS), respiratory symptoms, and clinical variables was also assessed. Material and Methods  The subjects were prospectively screened for OSA through the Berlin Questionnaire and type I polysomnography. The Epworth Sleepiness Scale and the Respiratory Symptoms Questionnaire were used for assessing OSA-related symptoms. Quality of life was assessed by means of the Short Form 36 Health Survey. Results  The sample comprised 20 adults with TCS (55.0% female), aged 22.6 ± 5.8 years. Mean values of systemic blood pressure (113.0 ± 12.6/68.0 ± 9.5mmHg), body mass index (22.9 ± 5.9kg/m ² ), neck (34.1 ± 4.3cm), and waist circumference (80.4 ± 13.6cm) characterized the sample. A high risk for OSA was detected in 35% of the sample. Polysomnography results indicated an OSA frequency of 44.4%, with a median apnea-hypopnea index (AHI) value of 3.8 events/hour (minimum = 0.2; maximum = 77.5). Snoring (75.0%), nasal obstruction (70.0%) and EDS (20.0%) were the reported OSA-related symptoms. Quality of life median scores were 72.3 points (minimum = 45.0; maximum = 91.1). Strong positive correlations between AHI versus waist circumference and AHI versus systolic blood pressure were found. Moderate positive correlations between AHI versus body mass index and AHI versus neck circumference were detected. Negative correlation between AHI versus vitality were also observed. Conclusion  Adults with TCS are at high risk for OSA, which is associated with respiratory symptoms, altered anthropometric measurements, increased systolic pressure and impairment of quality of life.

Psychometric evaluation of PHQ-9 and GAD-7 among community health volunteers and nurses/midwives in Kenya following a nation-wide telephonic survey

Background

Nurses/midwives and Community Health Volunteers (CHVs) are exposed to chronic stressors putting them at risk of developing mental health problems. This has been exacerbated by the COVID-19 pandemic. There is limited empirical evidence of the burden of mental health problems among health care workers partly due to the lack of adequately standardized and validated measures for use among health care workers in Sub-Saharan Africa. This study aimed to perform the psychometric evaluation of the PHQ-9 and GAD-7 administered to nurses/midwives and CHVs across 47 counties in Kenya.

Methods

Between June and November 2021, a national survey on mental well-being and resilience among nurses/midwives and CHVs was conducted via telephone interviews. The survey had a total sample size of 1907 nurses/midwives and 2027 CHVs. Cronbach's alpha and MacDonalds' omega were used to evaluate the scale's internal consistency. Confirmatory Factor Analysis (CFA) was used to test the one-factor structure of the scales. Multi-group CFA was applied to evaluate the generalizability of the scales across the Swahili and English versions, and among male and female health workers. The Spearman correlation was used to assess the tools' divergent and convergent validity.

Results

The internal consistency of PHQ-9 and GAD-7 was good, with alpha and omega values above 0.7 across study samples. CFA results indicated a one-factor structure of the PHQ-9 and GAD-7 for both nurses/midwives and CHVs. Multi-group CFA showed that both scales were unidimensional across both language and sex. The PHQ-9 and GAD-7 were significantly negatively correlated with resilience and work engagement, supporting divergent validity. The PHQ-9 and GAD-7 were also significantly positively correlated with resilience and work engagement, supporting divergent validity.

Conclusion

The PHQ-9 and GAD-7 are unidimensional, reliable, and valid tools for screening depression and anxiety among nurses/midwives and CHVs. The tools can be administered in a similar population or study setting using either Swahili or English.

Psychometric Evaluation of the Postoperative Recovery Profile

Aim

To further evaluate the postoperative recovery profile regarding its psychometric properties.

Background

The postoperative recovery profile is an instrument for the self-assessment of general postoperative recovery that has received increased attention within nursing research. However, psychometric evaluation during development was sparse.

Design

Psychometric evaluation was done using classical test theory.

Method

Data quality, targeting, reliability, and scaling assumptions were measured. In addition, confirmatory factor analysis was used to evaluate construct validity. Data collection was made during 2011-2013.

Result

Data derived from this study showed acceptable quality; however, item distribution was skewed, with ceiling effects in the majority of items. Cronbach's alpha showed high internal consistency. Item-total correlations indicated unidimensionality, whereas six items demonstrated high correlations pointing at redundancy. The confirmatory factor analysis confirmed problems related to dimensionality as the five proposed dimensions were highly correlated with each other. Furthermore, items were largely uncorrelated with the designated dimensions.

Conclusion

This study shows that the postoperative recovery profile needs to be further developed to serve as a robust instrument within nursing as well as medical research. Arguably, values from the instrument should not be calculated at a dimensional level for the time being because of discriminant validity issues.

Validation of the adapted female sexual function index among Chinese cisgender heterosexual women and sexual and gender minority women

BACKGROUND

The Female Sexual Function Index (FSFI) remains the most widely used scale for assessing female sexual function. However, while an adapted version of the FSFI has been proven to be suitable for Western sexual minority women, it has yet to be used in China.

AIM

This study aimed to validate the Mandarin Chinese version of the adapted FSFI among Chinese cisgender heterosexual women and sexual and gender minority women, and evaluate its psychometric properties.

METHODS

A cross-sectional online survey was conducted. The modified scoring method related to zero responses was examined, and structural validity, internal consistency, internal reliability, convergent validity, and known-group validity were evaluated.

OUTCOMES

The primary measure was the adapted FSFI, and the Positive Sexuality Scale and the New Sexual Satisfaction Scale-Short Form were used to test convergent validity.

RESULTS

A total of 431 Chinese adult women were recruited, including 193 cisgender heterosexual women and 238 sexual and gender minority women. Confirmatory factor analysis using the original scores supported the original 6-factor model. Using both Cronbach's α and McDonald's ω, the results showed that the values of the total scale and 6 subscales were in the 0.76 to 0.98 and 0.83 to 0.98 ranges, respectively, indicating satisfactory reliability. Moderate-to-strong correlations among the total FSFI scores and positive sexuality and sexual satisfaction were found (r = 0.32-0.71), supporting good convergent validity.

CLINICAL IMPLICATIONS

The adapted FSFI facilitates the use of more inclusive language in the clinical setting, allowing for a more comprehensive and unbiased assessment of sexual function in all women.

STRENGTHS AND LIMITATIONS

This study recruited both cisgender women of varied sexual orientations and gender minorities who were assigned female at birth, demonstrating that the adapted FSFI could be suitably applied to sexual minority populations. However, from a fully inclusive perspective of sex and gender, there is no research on how to accurately evaluate transgender women with female external genitalia or appropriately assess those with a female reproductive system but who do not self-identify as female. Therefore, more in-depth research is needed to further revise the FSFI for better use in the wider female population.

CONCLUSION

This Chinese version of the adapted FSFI has good psychometric properties and is a reliable and valid instrument to assess female sexual function. Furthermore, the modified scoring method could be an effective alternative among samples of sexually inactive women.

Translation and validation of the PPSC-PNP instrument to measure parental satisfaction with care from pediatric nurses in China

PURPOSE

To modify and translate the Parents' Perceptions of Satisfaction with Care from Pediatric Nurse Practitioners instrument into Chinese, culturally adapt and initially test it to assess parental satisfaction with care from all levels of pediatric nurses in a pediatric inpatient care context.

DESIGN AND METHODS

The instrument was translated and culturally adapted following a standardized guideline for the translation and cross-cultural adaptation of self-report measures. Content validity, discriminative validity, internal consistency and test-retest reliability were examined.

RESULTS

Four main issues were identified in the translation and cultural adaptation stage. Modifications were therefore made to the Chinese Parents' Perceptions of Satisfaction with Care from Pediatric Nurses instrument. The item-level content validity indexes for the Chinese instrument ranged between 0.83 and 1.0. The Cronbach's alpha coefficient was 0.95, and the intra-class correlation coefficient for test-retest reliability was 0.44.

CONCLUSION

The Chinese Parents' Perceptions of Satisfaction with Care from Pediatric Nurses instrument has good content validity and internal consistency and can be considered a suitable clinical evaluation tool to measure parental satisfaction with care from pediatric nurses in pediatric inpatient settings in China.

PRACTICE IMPLICATIONS

The instrument is anticipated to be useful in strategic planning for Chinese nurse managers responsible for patient safety and quality of care. Additionally, it has the potential to serve as a tool to enable international comparisons in parental satisfaction with care from pediatric nurses after further testing.

Longitudinal analysis of the Non-Motor Symptoms Scale in Parkinson's Disease (NMSS): An exploratory network analysis approach

Introduction

Parkinson's disease (PD) is a multisystem neurodegenerative disorder characterized by motor and non-motor symptoms. In particular, non-motor symptoms have become increasingly relevant to disease progression. This study aimed to reveal which non-motor symptoms have the highest impact on the complex interacting system of various non-motor symptoms and to determine the progression of these interactions over time.

Methods

We performed exploratory network analyses of 499 patients with PD from the Cohort of Patients with Parkinson's Disease in Spain study, who had Non-Motor Symptoms Scale in Parkinson's Disease ratings obtained at baseline and a 2-year follow-up. Patients were aged between 30 and 75 years and had no dementia. The strength centrality measures were determined using the extended Bayesian information criterion and the least absolute shrinkage and selection operator. A network comparison test was conducted for the longitudinal analyses.

Results

Our study revealed that the depressive symptoms anhedonia and feeling sad had the strongest impact on the overall pattern of non-motor symptoms in PD. Although several non-motor symptoms increase in intensity over time, their complex interacting networks remain stable.

Conclusion

Our results suggest that anhedonia and feeling sad are influential non-motor symptoms in the network and, thus, are promising targets for interventions as they are closely linked to other non-motor symptoms.

Validation of the Japanese version of the quality of life-Alzheimer's disease for nursing homes

OBJECTIVES

This study aims to validate the Japanese version of Quality of Life-Alzheimer's Disease for Nursing Homes (QOL-AD NH). This is the modified version of QOL-AD, initially developed for residents living with dementia in long-term care settings.

METHODS

Psychometric assessment was conducted in a sample of 101 residents and their professional care staff to obtain self-ratings and proxy-ratings of QOL, respectively. Residents' behavior was observed using Dementia Care Mapping (DCM) method, and their mood/engagement (ME) value was evaluated as a proxy measure of QOL.

RESULTS

Self-ratings were higher than proxy-ratings (t = 10.22, p<.001), with moderate correlation (r=.51, p<.001) and strong internal consistency (α=.87 for both). The exact agreement between the two groups was 38.23%. Convergent validity was confirmed with ME value and positive engagements of DCM. Exploratory factor analysis was performed for further validity testing. Three factors - self and life overall, social environment, and physical and psychological health, accounted for 85.9% of the total variance with Cronbach's α of .87, .73, .90, respectively.

CONCLUSION

Using a validated Japanese version of the QOL-AD NH may help assess the QOL of older residents living in long-term care settings to improve the continuum of care for dementia.

Psychometric evaluation of the Swedish version of the PROMIS Sexual Function and Satisfaction Measures in clinical and nonclinical young adult populations

Background

The Patient-Reported Outcomes Measurement Information System (PROMIS®) Sexual Function and Satisfaction (SexFS) version 2.0 measurement tool was developed to assess sexual functioning and satisfaction in the general population regardless of health condition and sexual orientation.

Aim

The study aimed to evaluate the psychometric properties of the Swedish version of the PROMIS SexFS measure in clinical and nonclinical populations of young adults (aged &lt;40 years).

Methods

The SexFS was answered by a clinical population of young adult women (n = 180) and men (n = 110) with breast cancer and testicular cancer, respectively, and a nonclinical population of young adult women (n = 511) and men (n = 324) from the general population. Psychometric properties were evaluated by examining data quality (score distribution, floor and ceiling effects, proportion of missing data), construct validity (corrected item, total correlation, scaling success), and reliability (Cronbach α).

Outcomes

The following domains of the SexFS 2.0 were investigated: Vaginal Lubrication, Vaginal Discomfort, Vulvar Discomfort- Clitoral, Vulvar Discomfort- Labial, Erectile Function, Interest in Sexual Activity, Satisfaction With Sex Life, Orgasm– Ability, and Orgasm- Pleasure.

Results

The Swedish version of the SexFS 2.0 generated data of acceptable quality. Some noteworthy floor or ceiling effects were identified across domains and respondent groups. Corrected item totals were used to express the coherence between an item and the other items in the domain. The correlation coefficients were above 0.40 for all items, except for 1 of the items within the Vaginal Discomfort domain and for the items in the Erectile Function domain in the nonclinical group of men. High proportions of scaling success were noted across domains (96%-100%). Reliability was satisfactory (α = 0.74-0.92) for all domains, expect for Erectile Function of the nonclinical group (α = 0.53), due to low variability in item responses, which was improved somewhat (α = 0.65) when combined with the clinical group.

Clinical Implications

A flexible tool to measure self-reported sexual function and satisfaction in young men and women is available for researchers and clinicians in Sweden.

Strengths and Limitations

The nationwide population-based sample of patients with cancer, identified from national quality registers, minimized selection bias. However, men in the general population had a lower response rate (34%) compared to the other groups, which introduced a risk of bias in estimates. The psychometric evaluation was limited to young adults (aged 19-40 years).

Conclusion

The results provide evidence for the validity and reliability of the Swedish version of the SexFS measure for the assessment of sexual functioning and satisfaction in young adults from both clinical and nonclinical populations.

Measurement Properties of the Simplified Chinese Version of the Lumbar Spine Instability Questionnaire for Patients With Low Back Pain in Mainland China

STUDY DESIGN

A prospective study.

OBJECTIVE

To develop a simplified Chinese version of Lumbar Spine Instability Questionnaire (SC-LSIQ) and test its measurement properties.

SUMMARY OF BACKGROUND DATA

The LSIQ has been translated into several languages. Different versions of LSIQ have proved good reliability and validity in evaluating patients with low back pain. However, there is no simplified Chinese version of LSIQ (SC-LSIQ).

MATERIALS AND METHODS

The SC-LSIQ has been translated into a simplified Chinese version according to a standard procedure. A total of 155 patients with low back pain completed the SC-LSIQ along with Oswestry Disability Index, Roland-Morris disability questionnaire, Tampa Scale for Kinesiophobia, and visual analogue scale (VAS). The internal consistency, test-retest reliability, and validity of SC-LSIQ were then calculated to evaluate the measurement properties of SC-LSIQ.

RESULTS

The results of SC-LSIQ demonstrated that there was no ceiling or floor effect detected. The Cronbach α coefficient of 0.911 determined a well internal consistency. The intraclass correlation coefficient (0.98) presented an excellent reliability of SC-LSIQ. The Pearson correlation coefficient (r) showed that the SC-LSIQ was excellent correlated to Oswestry Disability Index (r=0.809), Roland-Morris disability questionnaire (r=0.870), and Tampa Scale for Kinesiophobia (r=0.945,). Furthermore, it moderately correlated to visual analogue scale (r=0.586).

CONCLUSION

The SC-LSIQ features good internal consistency, reliability, and validity for evaluating Chinese patients with LBP. Results suggest that the SC-LSIQ can be appropriately applied to patients with LBP in routine clinical practice.

Health-related quality of life in Welsh adults: psychometric properties of the SF-36v2 and normative data

OBJECTIVES

The use of normative data has become well-accepted and a common strategy to interpret individual's health outcome scores, which can help in making decisions. The objectives of this study were to obtain population normative data for the domains and component summaries of the 36-item SF-36® Health Survey (SF-36), and to evaluate its reliability and construct validity.

METHODS

This study was conducted using population-based data from the Welsh Health Survey (WHS; 2011-2015). This study used version 2 of the SF-36 (SF-36v2® Health Survey). The descriptive statistics and normative data for the eight domains and two summaries, physical component summary (PCS) and mental component summary (MCS), were calculated. Reliability assessment used internal consistency methods and construct validity assessment used known group comparisons and item-scale correlations.

STUDY DESIGN AND SAMPLE

We performed a secondary analyses of data from the Welsh Health Survey (WHS).

RESULTS

This study included 74,578 participants aged 16 years or older (53.6% were women). Participants aged 16-24 years scored higher on SF-36 scale than older groups on all domains. The SF-36 profiles by age group demonstrated lower scores for older age groups, with the most pronounced differences shown on the physical-related scales. Across the age groups, men had higher PCS and MCS scores than women. All SF-36 domains and PCS and MCS achieved a good to excellent internal consistency reliability exceeding 0.7. The scales demonstrated construct validity by showing associations with a range of factors known to be related to health.

CONCLUSIONS

This study provides SF-36 normative data for Wales based on a representative data and confirms the construct validity and reliability of the SF-36.

Psychometric evaluation of Korean version of COVID-19 fear scale (K-FS-8): A population based cross-sectional study

COVID-19-related fear negatively affects the public's psychological well-being and health behaviours. Although psychological distress including depression and anxiety under COVID-19 is well-established in literature, research scarcely evaluated the fear of COVID-19 with a large sample using validated scale. This study aimed to validate a Korean version of fear scale(K-FS-8) using an existing fear scale(Breast Cancer Fear Scale; 8 items) and to measure the fear of COVID-19 in South Korea. A cross-sectional online survey was conducted with 2235 Korean adults from August to September 2020. The Breast Cancer Fear Scale was translated from English into Korean using forward-backward translation, and then face validity was assessed. Patient Health Questionnaire-4 and Primary Care Post-Traumatic Stress Disorder Screen for DSM-5 were used for assessing convergent validity of K-FS-8, and item response theory analysis was also conducted to further validate the K-FS-8. This study confirmed the validity and reliability of the K-FS-8. The validity of the scale was confirmed by convergent validity, known-group validity and item response theory analysis, and internal consistency was also examined(Cronbach's α coefficient = 0.92). This study also identified that 84.6% participants had high COVID-19 fear; whilst 26.3%, 23.2% and 13.4% participants had high risk of post-traumatic stress disorder, depressive and anxiety symptoms, respectively. The K-FS-8 showed the acceptability measuring the fear of COVID-19 in the Korean population. The K-FS-8 can be applied to screen for fear of COVID-19 and related major public health crises identifying individuals with high levels of fear in primary care settings who will benefit from psychological support.

Knowledge and perception of primary care healthcare professionals on the use of artificial intelligence as a healthcare tool

Objective

The rapid digitisation of healthcare data and the sheer volume being generated means that artificial intelligence (AI) is becoming a new reality in the practice of medicine. For this reason, describing the perception of primary care (PC) healthcare professionals on the use of AI as a healthcare tool and its impact in radiology is crucial to ensure its successful implementation.

Methods

Observational cross-sectional study, using the validated Shinners Artificial Intelligence Perception survey, aimed at all PC medical and nursing professionals in the health region of Central Catalonia.

Results

The survey was sent to 1068 health professionals, of whom 301 responded. And 85.7% indicated that they understood the concept of AI but there were discrepancies in the use of this tool; 65.8% indicated that they had not received any AI training and 91.4% that they would like to receive training. The mean score for the professional impact of AI was 3.62 points out of 5 (standard deviation (SD)  =  0.72), with a higher score among practitioners who had some prior knowledge of and interest in AI. The mean score for preparedness for AI was 2.76 points out of 5 (SD  =  0.70), with higher scores for nursing and those who use or do not know if they use AI.

Conclusions

The results of this study show that the majority of professionals understood the concept of AI, perceived its impact positively, and felt prepared for its implementation. In addition, despite being limited to a diagnostic aid, the implementation of AI in radiology was a high priority for these professionals.

Translation and validation of the STARx questionnaire in transitioning Chinese adolescents and young adults with chronic health conditions

BACKGROUND

Adolescent/young adults (AYAs) with chronic conditions must undergo healthcare transition (HCT) preparation until their mid-twenties. Valid HCT readiness measures are lacking in China.

METHODS

The present study translated, back-translated, and adapted the Self-Management and Transition to Adulthood with Rx = Treatment (STAR_x) Questionnaire. We examined the psychometric properties of this tool in a relatively large in-patient sample of AYAs with various chronic health conditions at a Chinese tertiary general hospital.

RESULTS

We enrolled 624 AYAs aged 10-25 years (19.66 ± 3.64) with various chronic health conditions. The Chinese version of the STAR_x Questionnaire demonstrated excellent internal consistency (Cronbach's alpha = 0.83) and reliability with a two-week test-retest (ICC = 0.88, p < .001). Furthermore, the Chinese version revealed a three-factor structure (self-management, disease knowledge, and provider communication) consistent with the revised English version of the STAR_x Questionnaire. In terms of discriminant validity, the total score of the Chinese STAR_x Questionnaire showed a significant positive correlation with age but no gender differences were found. In terms of predictive validity, the Chinese STAR_x Questionnaire was significantly correlated with shorter length of hospitalization and higher frequency of emergency room visit, but the correlations became insignificant after controlling for age.

CONCLUSIONS

The results suggest that the Chinese version of the STAR_x Questionnaire is a robust HCT readiness tool in AYAs with chronic conditions and clinicians may find it useful to develop individualized interventions.

Spanish validation of the Modified Weight Bias Internalization Scale (WBIS-M) for adolescents

PURPOSE

Weight Bias Internalization (WBI) is pervasive and potentially damaging for health. Little is known about WBI in youth. As negative effects of WBI have been observed when controlling for BMI, measures that allow WBI to be assessed across different weight categories are needed. The Modified Weight Bias Internalization Scale (WBIS-M) is one of the most frequently used scales in this field. Our purpose was to obtain a Spanish validated version of the WBIS-M for adolescents across different weight statuses.

METHODS

The data were collected from 298 secondary students (mean age 14.31; 48.32% girls; 18.8% were overweight and 6.4% had obesity). Internal structure was examined by a cross-validation analysis, using both exploratory and confirmatory factor analyses in different subsamples.

RESULTS

Item 1 showed a psychometric anomalous functioning and was deleted. The one-factor structure of the 10-item version was confirmed with adequate fit ([EFA (KMO = 0.915, χ2(55) = 1075.633, p < 0.0001)]; [CFA (χ2(35) = 200.515; GFI = 0.995; PGFI = 0.992; NFI = 0.991; SRMR = 0.060)]). Internal consistency was high [Formula: see text] ω = 0.93). Significant correlations with the same set of external variables assessed in the original version (anti-fat bias, self-esteem, mood, body dissatisfaction, drive for thinness, binge eating), all of them correlates of WBI in adolescents, were found. Girls and participants with obesity obtained higher scores.

CONCLUSION

The results provide support for the validity and reliability of our WBIS-M version for use with adolescents across weight categories in Spain.

LEVEL OF EVIDENCE

Level III, evidence obtained from well-designed cohort studies.

Structural validity and internal consistency of the Shoulder Pain and Disability Index in Turkish patients with rotator cuff disease: A proposal of a new version

BACKGROUND

The Shoulder Pain and Disability Index (SPADI) is a widely used patient-reported outcome questionnaire in patients with shoulder diseases; however, the structural validity and the internal consistency of the Turkish SPADI is unclear in rotator cuff disease.

OBJECTIVE

To assess the internal structure of the Turkish SPADI in patients with rotator cuff disease.

METHODS

A total of 109 patients with unilateral rotator cuff disease were assessed. The COnsensus-based Standards for the selection of health Measurement INstruments checklist was used for the methodological design of the study. A confirmatory factor analysis was performed, and the model fit was assessed by using the comparative fit index (CFI), the Tucker-Lewis index (TLI), the root mean square error of approximation (RMSEA), and the standardized root mean square residual (SRMR). The factor structure was examined with a principal component analysis. The internal consistency was assessed using Cronbach's alpha.

RESULTS

The validity of the two subscales was not confirmed. The principal component analysis showed the Turkish SPADI consisted of one factor, and the one-factor model of the Turkish SPADI also was not confirmed. When two items were deleted, the one-factor model of the new version of the Turkish SPADI had a better fit (CFI = 0.978, TLI = 0.971, RMSEA = 0.058, SRMR = 0.043). The internal consistency of the new version of the Turkish SPADI was high (Cronbach's alpha = 0.92, 95% CI = 0.90-0.94).

CONCLUSIONS

We suggest that the modified version of the Turkish SPADI should be used for patients with rotator cuff disease. The total score of the modified version should be considered.

Development and validation of a novel cosmetics safety assessment scale (CSAS): Factual understanding of cosmetic safety and fostering international awareness

Background

Falsified cosmetics are increasingly common especially online through social media networks and mobile applications.

Objectives

This study developed and validated a novel tool to evaluate the safety of cosmetics and personal care products in the United Araba Emirates (UAE).

Method

This is methodological validation study and the data were derived from a cross-sectional study conducted on students and staff at Ajman University (AU) in the UAE. The study sample was selected via simple random sampling. The link to the survey was sent to potential respondents via email, and the responses were analysed using SPSS version 26. Content validity, factor analysis, and known group validity were employed to construct and validate an instrument that will enable the identification of cosmetics safety. The instrument’s reliability was evaluated using test-retest reliability, internal consistency, item internal consistency (IIC), and intraclass correlation coefficients (ICCs).

Results

The study sample included 978 participants. The content validity index for the final 24-item scale was 0.84. The Kaiser-Meyer-Olkin value was 0.959 with a statistically significant Bartlett’s test of sphericity (p <0.001). Factor analysis presented a three-component model. PCFA analysis found good fit values with 0.960 for the normed fit index, 0.977 for the comparative fit index, and 0.987 for the Tucker Lewis Index. All values were in excess of 0.95, and the root mean square error of approximation was below 0.06 (0.03); thus, the model had a good fit. Cronbach’s alpha also showed good consistency of the overall instrument (0.963), and all factors had a Cronbach’s alpha above 0.70. Each item on the instrument met the IIC correlation standard of ≥ 0.40, and there were good overall ICC statistics of 0.963 (0.959–0.966) for the instrument as a whole with statistical significance (p < 0.001). The instrument’s test-retest reliability was assessed by correlating the respondents’ identification scores at two time points with a four-week gap revealing a correlation coefficient of 0.870 (p-value <0.01). Participants holding a bachelor’s degree were more likely to be able to identify safe and authentic cosmetics than those with a high-school educational level (p = 0.015).

Conclusions

This study developed a novel validated instrument to determine the safety of cosmetics. The final questionnaire uses 24 items on three dimensions (13 items on hazard information, eight items on product identity, and three items on product handling and storage). The tool is concise and easy to complete, and it is suitable for use among the general population. The use of this instrument can promote greater collaboration between the consumer health regulatory authorities and inspection authorities thus increasing consumer satisfaction and public participation.

Short-form development of the specific module of the QLICD-CRF(V2.0) for assessing the quality of life of patients with chronic renal failure

Background

A short instrument would enhance the viability of a study. Therefore, we aimed to shorten the specific module (SPD-10) of the Quality of Life Instrument for Chronic Diseases - Chronic Renal Failure (QLICD-CRF) for assessing the quality of life of patients with chronic renal failure.

Methods

The 10-item SPD-10 was self-administered to 164 patients with chronic renal failure. A shortened form was first obtained by a tandem use of the classical test theory (CTT), the generalizability theory (GT), and the item response theory (IRT). In addition, we also shortened the SPD-10 by the Optimal Test Assembly (OTA).

Results

Both the tandem use of GT, CTT and IRT, and the OTA derived the same 7-item shortened version (SPD-7). It included items CRF1, CRF2, CRF3, CRF4, CRF6, CRF8, and CRF9 of the SPD-10. The SPD-7 had a Cronbach alpha of 0.78. The correlation coefficients of its total and factor scores with those of the SPD-10 were 0.96 and 0.98, respectively. Confirmatory factor analysis confirmed the unidimensional structure of the SPD-7, with the comparative fit index=0.96, the Tucker-Lewis index=0.94, and the root mean square error of approximation=0.09.

Conclusion

The short-form SPD-7 is reliable and valid for assessing the impact of clinical symptoms and side effects on the quality of life of patients with chronic renal failure. It is an efficient option without compromising the measurement performance of the SPD-10.

The validation of culturally appropriate scales to assess the family health climate in a multi-ethnic Asian population

Background

The Family Health Climate (FHC) is a family environment attribute postulated to influence the health behaviors of family members. It can be measured by domain scales for physical activity (FHC-PA) and nutrition (FHC-NU), which have been validated and used to identify health climate patterns in families in Western populations. To extend the use of the scales to Asian settings, this study aimed to adapt and validate the instruments for use in the multi-ethnic population of Singapore, accounting for language and cultural differences.

Methods

In Part A (n = 40) to adapt the scales for the Singapore population, we performed cognitive interviews, face validity testing and pre-testing of the instruments (n = 40). Besides English, the scales were translated into Chinese and Malay. In Part B (n = 400), we performed exploratory and confirmatory factor analyses respectively on two random samples. We also tested for item discriminant validity, internal consistency reliability, construct validity, and measurement invariance.

Results

The findings from the cognitive interviews in Part A led to scale adaptations to accommodate cultural and linguistic factors. In Part B, EFA on Sample I resulted in a three-factor model for the PA scale (accounting for 71.2% variance) and a four-factor model for the NU scale (accounting for 72.8% variance). CFA on Sample II indicated acceptable model fits: FHC-PA: χ² = 192.29, df = 101, p < 0.001, χ²/df = 1.90; SRMR = 0.049; RMSEA = 0.067; CFI = 0.969; TLI = 0.963; FHC-NU: χ² = 170.46, df = 98, p < 0.001, χ²/df = 1.74; SRMR = 0.036; RMSEA = 0.061; CFI = 0.967; TLI = 0.960. The scores of family members demonstrated significant agreement on the FHC-PA (Sg) [ICC_{(2, 2)} = 0.77] and FHC-NU (Sg) [ICC_{(2, 2)} = 0.75] scales. Findings suggest good evidence for item discriminant validity, internal consistency reliability, construct validity, and measurement invariance. Short versions of the scales were also developed.

Conclusion

We adapted, translated and validated the scales for assessing the health climate of families in Singapore, including the development of short versions. The results showed good psychometric properties and the constructs had significant relationships with health behaviors and routines. Improving our understanding of family influences on individual health behavior will be important in developing multi-level strategies for health promotion and chronic disease prevention.

Is traditional back translation enough? Comparison of translation methodology for an ASD screening tool

Early identification of autism spectrum disorders (ASD) in non-English speaking children often relies on translation of English ASD screening measures. Most measures employ a forward-back translation approach, despite data suggesting that this method may result in poor psychometric properties. Some studies in non-ASD fields have suggested that a rigorous method of translation with cultural adaptation may yield better psychometric properties, but no studies in the ASD field have compared the two approaches directly. This investigation compares these two translation methodologies to determine if they produce psychometrically similar or dissimilar measures. Three hundred and eighty US-based Spanish-speaking caregivers of children 8-16 months old were randomly assigned to complete either a forward-back Spanish translation or a rigorous translation with cultural adaptation of a parent-report ASD screening tool. Measurement invariance analyses determined that the two translations were psychometrically dissimilar. Additional qualitative explanatory methods using cognitive interviews examined textual differences and participant preferences between non-invariant items. LAY SUMMARY: Autism screening questionnaires created in English need to be translated into other languages so non-English speaking parents can fill them out accurately. Traditionally, researchers have not considered cultural differences when they translate these questionnaires. When we compared a direct translation to a translation with cultural adaptations, the two questionnaires were statistically different. Parents interpreted and responded to the same questions differently, depending on which version they filled out.

Psychometric Properties of the Emotional Eater Questionnaire in University Students

Emotional Eating (EE) patterns have been shown to play a relevant role in the development of overweight and obesity. The aim of this study was to analyze the factor structure and psychometric properties of the Emotional Eater Questionnaire (EEQ) in university students from Huelva. The EEQ was administered to 1282 students (age 22.00 (±5.10), BMI 23.59 (±6.74)), belonging to the University of Huelva. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out. The internal structure of the questionnaire, internal consistency, test-retest reliability, and convergent validity were analyzed. Principal component analysis of the questionnaire showed two dimensions, explaining 56% of the variance. Internal consistency showed a Cronbach's alpha of 0.859 globally, and of 0.841-0.855 if the items were removed. The corrected item-total correlation yielded values of 0.444-0.687. The test-retest stability was ICC = 0.924 (p < 0.001). The data showed significant correlations between EEQ and the rest of the variables, and a Spearman's Coefficient ranging from -0.367 to 0.400. The fit indexes were good for the confirmatory factor analysis. The results obtained with this structure found an adequate reliability and validity of the questionnaire in comparison with previous studies.

A comparison of the measurement properties of the PROMIS Fatigue (MS) 8a against legacy fatigue questionnaires

BACKGROUND

Amidst the growing number of patient-reported outcome (PRO) measures of fatigue being used in multiple sclerosis (MS) clinical trials and clinics, evidence-based consensus on the most appropriate and generalizable measures across different settings would be beneficial for clinical research and patient care. The objective of this research was to compare the validity and responsiveness of scores from the PROMIS Fatigue (MS) 8a with those of the Fatigue Severity Scale (FSS) and the Modified Fatigue Impact Scale (MFIS), across US and UK MS populations.

METHODS

Two observational studies were performed in MS populations as part of a PRO measure development project, including a cross-sectional study in two tertiary US MS centers (n = 340) and a 96-week longitudinal study in the UK MS Register cohort (n = 352). In post-hoc analyses, we examined  relative validity, based on ability to discriminate across patient groups with different fatigue levels or functional status at baseline (i.e., ANOVA-F PRO_X ÷ ANOVA-F PROMIS (MS) 8a), and relative responsiveness, based on baseline-to-Week-52 score change (effect sizes) across fatigue or functional status response groups .

RESULTS

Mean ± standard deviation (SD) age was 44.6 ± 11.3/50.0 ± 9.7; and 72.9%/77.3% were female (US/UK samples). The mean PROMIS Fatigue (MS) 8a T-score ± SD at baseline was 57.7 ± 10.5/58.9 ± 9.3 (US/UK samples). Compared with the PROMIS Fatigue (MS) 8a, relative validity (anchor: Global Health Score [GHS] fatigue global question) was 85% for MFIS symptom score, 48% for MFIS total score, and 44% for the FSS. Relative to the FSS, PROMIS Fatigue (MS) 8a scores were more sensitive to worsening (effect size = -0.43 versus -0.18) as well as improvement (effect size = 0.5 versus 0.2) in fatigue (≥1-point increase/decrease in GHS fatigue global question) over 52 weeks of follow-up. A similar pattern of score changes was observed based on a second anchor.

CONCLUSION

The PROMIS Fatigue (MS) 8a scores showed higher responsiveness to fatigue changes than those of the FSS. The PROMIS measure also had higher precision in differentiating levels of fatigue compared to the FSS, the MFIS physical, and MFIS total scores. These differences have practical implications for the application of these questionnaires in both clinical practice and research settings (e.g., sample size estimation in clinical trials).

Development and Validation of a Tool to Improve Community Pharmacists’ Surveillance Role in the Safe Dispensing of Herbal Supplements

Background: There has been an appreciable increase in the use of herbal supplements, including immune boosters, during the current COVID-19 pandemic. However, there are concerns with falsified herbal supplements.

Objectives: Developed a new questionnaire that can potentially help community pharmacists identify the extent of falsified herbal supplements.

Methods: A 9-month cross sectional study was conducted among 500 community pharmacies across United Arab Emirates. A new 5-factor, 24-itmes scale was developed based on current labelling requirements across countries and piloted. This included seven items on identified uses and contraindication, seven items on hazard identification, four items on product identity, three items on packaging and product insert and three items on product handling and storage. The face and content validity of the scale was assessed via the content validity index (CVI). Its construct validity was tested using an exploratory factor analysis (EFA) via principally component analysis (PCA). The model was subsequently confirmed through partial confirmatory factor analysis (PCFA). Its reliability was assessed via test-retest reliability, internal consistency, item internal consistency (IIC), and intraclass correlation coefficients (ICCs).

Results: The CVI of the finalized questionnaire was 0.843. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.891, and Bartlett’s test of sphericity indicated significance (p-value < 0.001). Confirmation of the subsequent 5-domains was achieved through PCFA using maximum likelihood analysis with oblimin rotation. The PCFA obtained values was 0.962 for NFI, 0.977 for CFI, and 0.987 for the Tucker Lewis Index. All values were greater than 0.95, and the RMSEA value was 0.03 (i.e., less than 0.06). Consequently, the model had a good fit. All domains demonstrated Cronbach’s alpha coefficients above 0.70, with 0.940 for the full instrument. Meanwhile, all items met the IIC correlation standard of ≥0.40. The instrument presented good ICC statistics of 0.940 (0.928–0.950) as well as statistical significance (p < 0.001). Community pharmacists with more than 10 experience years were more likely to identify falsified herbal supplements compared to those with 1–10 years experience (p < 0.001).

Conclusion: This study developed and validated a new instrument to identify safe herbal supplements, which should enhance the role of the community pharmacists in the safe and effective treatment of suitable patients with herbal supplements.

Psychometric Properties of the Persian Version of the Falls Behavioral Scale in Seniors

Background: The identification of the causes of risky behaviors is necessary to prevent the occurrence of injuries and reduce its costs. The present study aimed to translate and evaluate the validity and reliability of the Falls Behavioral (FaB) Scale in Iranian seniors. Methods: This methodological study was conducted on 300 seniors aged 60 years and older referring to retirement centers. After permission, the recommended forward-backward procedure was adopted to translate the original English version of the questionnaire. Thereafter, the content, face validity, and construct validity of the scale were determined and taken into consideration. In addition, the known-groups comparison (seniors with and without a history of falls), as well as convergent and divergent validity, was used to evaluate construct validity. Finally, internal consistency and the test-retest analysis were performed to assess the reliability of the FaB scale. Results: The results of the known-groups comparison demonstrated that the mean score of the FaB scale was higher in the seniors with a history of falls as compared to that in their counterparts without such an experience. The obtained scores on FaB scale, Activities-Specific Balance Confidence (ABC) scale (r=-0.214, P<0.01), and Falls Efficacy Scale-International (FES-I) (r=0.256, P<0.01) represented a significant correlation, confirming the construct validity of the scale. The Cronbach’s alpha of the total scale and test-retest reliability within one week were obtained as 0.71 and 0.91, respectively. Conclusion: As evidenced by the results of this study, the Persian version of the FaB scale is a valid and reliable instrument; therefore, it can be used to assess the behavioral fall risk factors, as well as fall prevention interventions in older people. It is suggested that in future studies, researchers focus on the assessment of more psychometric properties of this scale, especially sensitivity and specificity.

Translation, Cross-Cultural Adaptation, and Psychometric Testing of Yoruba Version of the EQ-5D Questionnaire in Patients With Musculoskeletal Disorders

Background

The EuroQol-5 Dimension (EQ-5D) is a generic self-administered questionnaire used for the measurement and economic valuation of a wide range of health conditions, which necessitates its existence and adaptation in different languages. Currently, the tool does not exist in any Nigerian language. This study aimed to translate, cross-culturally adapt, and determine the reliability and validity of the Yoruba version of the EQ-5D-5L questionnaire.

Methods

The International Quality of Life Assessment (IQOLA) project guidelines, involving forward translation, reconciliation and harmonization, backward translation, and reconciliation of problematic items were used in the Yoruba translated version of the EQ-5D-5L (EQ-5D-Yor). A total of 113 and 109 persons with musculoskeletal disorders participated in the validity and 7-day test-retest reliability testing of the EQ-5D-Yor. Convergent and discriminant validity of the EQ-5D-Yor were determined using the Yoruba version of the 12-Item Short-Form Health Survey (SF-12) (SF-12-Y) and Visual Analog Scale (VAS). Data were analyzed using descriptive and inferential statistics of Spearman correlation, Intra-Class Correlation, Cronbach alpha, and multi-trait scaling analysis. Alpha level was set as p < 0.05.

Results

The construct validity of the EQ-5D-Yor yielded Spearman rho ranging from 0.438 to 1.000, with the EQ-VAS having the highest co-efficient (r = 1.000; p = 0.001). The convergent validity of the EQ-5D-Yor index with scales and domains of the SF-12-Y yielded no significant correlations (p < 0.05), except for the physical functioning scale (r = −0.709, p = 0.001). On the other hand, the divergent validity of the EQ-5D-Yor index with VAS yielded a moderate negative correlation (r = −0.482; p = 0.001). The Intra-class Correlation Coefficient (ICC) and Cronbach's alpha for the test-retest reliability of the EQ-5D-Yor were 1.000 and 0.968. The confirmatory factor analysis showed the factor loadings were poor when including VAS in the model.

Conclusion

The EQ-5D-Yor has acceptable validity and reliability and can be used as a valid tool among Yoruba speaking population with musculoskeletal disorders.

Development and validation of a Perceived Relocation Stress Scale for older individuals transferred to long-term care facilities in Taiwan

BACKGROUND

The aim of the current study was to develop and validate a Perceived Relocation Stress Scale.

METHODS

A cross-sectional research design was used. A total of 175 older adults residing in long-term care facilities in Southern Taiwan for at least 1 y were recruited. An exploratory factor analysis was performed to examine item convergent and discriminant validity. Concurrent validity was checked using the Depression Anxiety and Stress scale. The reliability was analyzed using Cronbach's alpha and intraclass correlation coefficients.

RESULTS

The face and content validity of the scale were verified by adequately measuring the scale items. Factor analysis consisted of four components (challenge/chance, positive appraisal, threat, loss), with a total variance of 67.35%. The content validity was determined by an expert panel to systematically examine the relevance of all items. The results of item convergent and discriminant validity supported the constructs of the scale. The alpha coefficient for the overall scale was .958, indicating good internal consistency reliability.

CONCLUSIONS

The Perceived Relocation Stress Scale is a reliable and valid measurement to assess the stress perceived by older individuals being transferred to a long-term care facility.

Reliability and validity of an employer-completed safety hazard and management assessment questionnaire

INTRODUCTION

Managing and improving occupational safety and health requires evaluating performance. Organizations are encouraged to use both lagging indicators (such as injury rates and costs) and leading indicators (such as questionnaire-assessed safety hazards and management practices) for this purpose, but the association between types of indicators over time can be complex. Longitudinal data can assist in clarifying these associations and increasing indicator utility.

METHOD

Employer data were used to evaluate the reliability and predictive validity of a safety management questionnaire. Employers' longitudinal questionnaire responses and workers' compensation (WC) claims data were analyzed using a marginal model with time-dependent covariates. Multivariable Poisson and linear regression analyses with claim rate and logarithmic cost, respectively, as dependent variables were carried out after adjusting for industry sector and size. Questionnaire data were used to evaluate questionnaire scaling properties and to assess generalizability of results.

RESULTS

One safety management scale was associated with a better WC outcome as predicted and two scales were unexpectedly associated with poorer WC claim outcomes. Analyses assisted in interpreting the latter results, suggesting that WC outcomes were a stimulus for change in some cases. Twelve hazards assessed on the questionnaire were associated with poorer WC claim outcomes as predicted.

CONCLUSIONS

This study extends leading indicator research using longitudinal questionnaire and WC claims data from employers. Analyses provided insight into associations between leading and lagging indicators, emphasizing the importance of both for safety improvement. Safety management questionnaire scales were predictive of WC claim outcomes, although support for hazard assessments as leading indicators was stronger.

PRACTICAL APPLICATIONS

This study supports the use of employer-completed hazard assessment questionnaires for targeting and prioritizing improvement efforts. Employer-completed safety management scales may be useful for directing improvement efforts, although the conditions under which they are completed, including submission to insurers, require additional consideration.

Cultural adaptation and psychometric assessment of the Persian version of the lumbar spine instability questionnaire

BACKGROUND

The Lumbar Spine Instability Questionnaire (LSIQ) is a self-reported measure of clinical instability of the lumbar spine. This study aimed to translate and culturally adapt the LSIQ into Persian language (LSIQ-P) and to evaluate its reliability and validity in a sample of patients with chronic non-specific low back pain (LBP).

METHODS

In a cross-sectional study, the LSIQ was translated using guidelines. Participants with chronic non-specific LBP, aged ≥ 18 years old, answered an online survey consisting of LSIQ-P, the Persian Functional Rating Index (FRI), and the pain Numeric Rating Scale (NRS). Construct validity, internal consistency reliability, test-retest reliability, standard error of measurement (SEM), smallest detectable change (SDC), discriminant validity, and factor analysis were evaluated.

RESULTS

The LSIQ was successfully adapted into Persian. A sample of 100 participants with LBP and 100 healthy subjects completed the survey. Floor and ceiling effects were not observed. Cronbach's alpha = 0.767 and ICC_agreement = 0.78 indicated good internal consistency and test-retest reliability. The SEM and SDC were 1.53 and 4.24, respectively. Construct validity of LSIQ-P was confirmed with significant correlation with Persian FRI (r = 0.44, p < 0.001) and pain NRS (r = 0.30, p = 0.003). An evidence of discriminant validity was demonstrated by significant difference in LSIQ-P total scores between the patients with LBP and healthy subjects, and between the patients with high total score ≥ 9 and those with low total score < 9 on the LSIQ-P. The LSIQ-P was found a multidimensional instrument with eight items appeared being redundant.

CONCLUSIONS

The Persian LSIQ showed satisfactory metric characteristics of reliability and validity. Further studies are required to elucidate the internal structure of the LSIQ-P.

Bristol Breastfeeding Assessment Tool-Thai Version: Translation, Validity, and Reliability

BACKGROUND

In 2019, 14.0% of infants in Thailand were exclusively breastfed up to 6 months of age. To increase exclusive breastfeeding, an objective assessment measure would be useful to maternity care providers for appraising the problems encountered by new mothers' experiences with breastfeeding.

RESEARCH AIMS

To translate the Bristol Breastfeeding Assessment Tool from English into Thai; to assess the reliability and validity of the Thai Bristol Breastfeeding Assessment Tool; and to explore the relationship of a mother's self-efficacy to successful breastfeeding.

METHODS

Using a methodological design, we purposively sampled 302 new mothers from two tertiary hospitals in Thailand who had given birth to a single baby with an uncomplicated vaginal birth. The Thai Bristol Breastfeeding Assessment Tool's structure was examined using confirmatory factor analysis. Concurrent and convergent validity were assessed using the Thai LATCH instrument and Thai Breastfeeding Self-Efficacy Scale, respectively.

RESULTS

The inter-item Thai Bristol Breastfeeding Assessment Tool correlation coefficients were positive and strong. The correlation between scores of the Thai Bristol Breastfeeding Assessment Tool and Thai LATCH instrument were positive and strong and had acceptable concurrent validity. The confirmatory factor analysis model fit the Thai Bristol Breastfeeding Assessment Tool data perfectly and the Cronbach's alpha coefficient had acceptable internal reliability.

CONCLUSIONS

The Thai Bristol Breastfeeding Assessment Tool is a cross-culturally translated instrument equivalent to its English version and demonstrated acceptable validity and reliability. The instrument provides a mechanism for an objective assessment and monitoring system of optimal breastfeeding practices in Thai mothers with newborns.

Aim

To validate the psychometric properties of a questionnaire to measure adherence to treatment among people with type 1 diabetes mellitus and to evaluate its relationship with metabolic control.

Design

A cross‐sectional study of 167 adult people with type 1 diabetes mellitus recruited from the Endocrinology Service of University Hospital Doctor Peset (Spain).

Methods

The validity of the content, construct and reliability of the instrument were evaluated and the results correlated with levels of glycosylated haemoglobin.

Results

The questionnaire was composed of 25 items and 5 dimensions, with a score of 25–150 points and an internal consistency of 0.92, according to Cronbach's coefficient α. The content of validity ratio and the construct (exploratory functional analysis, Kaiser–Meyer–Olkin index and Barlett's spherical test) were adequate. We observed a significant correlation between glycosylated haemoglobin levels and treatment adherence.

Conclusion

The questionnaire to measure adherence to treatment in type 1 diabetes mellitus is consistent, reliable and valid, showing an excellent association with degree of metabolic control.

Healthy minds live in healthy bodies – effect of physical health on mental health: Evidence from Australian longitudinal data

It is well known that physical and mental health are closely related, with growing evidence for biological and behavioural pathways. Mostly the research has focussed on mental health as the key driver of this inter-connection; the extent physical health shapes mental health has received less attention. We aim to derive robust estimates of the unique role physical health may play in shaping mental health outcomes. To do so we use a novel approach, incorporating longitudinal and instrumental variable methods which can address the reciprocal relationship between physical and mental health, and the endogeneity of physical health, before estimating the physical to mental health pathway. A sample of 209,442 observations (or 24,966 unique individuals) aged 15 and over spanning 18 years (2002–2019) was extracted from the Household Income and Labour Dynamics in Australian Survey (HILDA). We find that physical activity and health shocks erode mental health via their impact on physical health with a one point improvement (or worsening) in physical health scores (0–100) resulting in a rise (or decline) of 0.43 points (or 43%) in mental health score.

What Drives Internet Entrepreneurial Intention to Use Technology Products? An Investigation of Technology Product Imagination Disposition, Social Support, and Motivation

Technological products such as computer, communication, and consumer electronic products, apps, smart wearables, and streaming services have become inseparable from people's lives. In technological fields of practice, imagination, creativity, innovation, and entrepreneurship may influence one another. A vivid imagination can generate creativity and trigger the entrepreneurial intention to "bring new things to the market." This study aims to understand the formation of internet entrepreneurial intention to use technology products. Drawing on social cognitive theory, this study explores and empirically tests how technology product imagination disposition and social support impact internet entrepreneurial intention to use technology products. Drawing from self-determination theory, this study proposes and examines the mediating role of intrinsic (challenge and enjoyment) and extrinsic motivation (compensation and outward motivation) in the relationship between technology product imagination disposition and internet entrepreneurial intention, as well as the relationship between social support and internet entrepreneurial intention. We conducted a survey of 568 adults in Taiwan and used partial least squares to test our hypotheses. The results show the following: (1) Technology product imagination disposition is positively associated with challenge, enjoyment, compensation, and outward motivation. (2) Social support is positively associated with challenge, enjoyment, compensation, and outward motivation. (3) Challenge, enjoyment, and outward motivation are positively associated with internet entrepreneurial intention to use technology products. (4) Technology product imagination disposition intensifies internet entrepreneurial intention to use technology products by strengthening challenge, enjoyment, and outward motivation. Social support intensifies internet entrepreneurial intention by increasing challenge, enjoyment, and outward motivation. The partial mediation model represents a significant improvement in the total effect over the direct effect. We discuss the implications of these results for research and internet entrepreneurship practices.
