Development and validation of the Somali WHOQOL-BREF among refugees living in the USA

Sociocultural determinants of health-associated quality of life among Afghan refugees in Pakistan: evidence from a multi-stage cross-sectional study

BACKGROUND

In the past few decades, there has been a significant increase in the number of refugees worldwide. Every individual deserves access to the fundamental right to health, and migration can have a substantial beneficial or detrimental effect on one's health. Foreign invasions and political instability in Afghanistan affected neighboring countries with the large influx of refugees. Discrepancies in quality of life between the host and refugee populations may lead to health inequalities. Investigations in Pakistan on the quality of life of Afghan refugees were scarce despite more than four decades of refugee status. Therefore, this study was initiated to assess the sociocultural determinants influencing health-associated quality of life among Afghan refugees in Pakistan.

METHODS

The Punjab province and Khyber Pakhtunkhwa province refugee populations were selected as the study population for cross-sectional research based on the inclusion criteria of majority refugee representation and female participation. Quantitative research methodology with pre-validated WHOQOL-BREF questionnaires was used for data collection via multi-stage probability sampling techniques. We collected data from 1,185 study participants and applied univariate and bivariate analyses. Inferential analyses included independent t-tests and ANOVA.

RESULTS

The average scores for the entire sample of Afghan refugees were highest for the social domain (58.78 ± 22.74), followed by the physical domain (53.29 ± 19.46), the general health domain (50.44 ± 20.10), the environmental domain (48.43 ± 16.30), and the psychological domain (46.52 ± 14.78). Age, marital status, family setup, mother language, number of years in the host country, residence type, family monthly income, access to health care, current health status, chronic health illness, substance abuse (smoking), cultural compatibility, linguistic barriers, and social inclusion were non-significant with all the subdomains in the inferential analysis using the independent t-test and analysis of variance.

CONCLUSION

The Afghan refugees' average scores across all health-associated quality-of-life domains were lower than Pakistan's host population and the standard cutoff criteria (< 60 indicates poor quality of life). The development of a national policy to include refugees in health insurance programs seems essential to improve the health-associated quality of life among Afghan refugees in Pakistan.

The impact of anxiety and depression on the quality of life of hemodialysis patients in a sample from Somalia

OBJECTIVE

The main objective of the present study was to determine the quality of life (QoL), depression, and anxiety levels in kidney failure patients undergoing hemodialysis (HD) treatment and examine the impact of depression and anxiety on the QoL of these patients in a sample from Somalia.

METHODS

A sample of 200 patients with kidney failure who were undergoing HD treatment approximately two to three times a week was included. All participants were administered a sociodemographic data form, the Patient Health Questionnaire-9 (PHQ-9), the Hospital Anxiety and Depression Scale (HADS), and the World Health Organization Quality of Life (WHO-QOL-BREF). Subjects on HD for less than 3 months prior to the study date were excluded.

RESULTS

Of the kidney failure patients, 200 patients, aged 18-86 years (median: 50.0; IQR: 25.0), consented and participated in the study. 58.5% of the participants were men; 64% had a kidney failure duration of 1-5 years, and 52.6% had a HD duration of 1-5 years. Mild symptoms of depression were found in 48%, while moderate-to-severe depressive symptoms were found in 13.5% of HD patients. Depression and anxiety were found to be significantly correlated with overall QoL, physical health, psychological health, social relationships, and environmental well-being. There were similar predictors of overall QoL, physical health, psychological well-being, social relationships, and environmental well-being relating to socio-demographic factors such as age, gender, family income, anxiety, and depression.

CONCLUSIONS

This study emphasizes the important role that anxiety, depression, and family income have in HD patients' QoL in Somalia. It highlights the significance of regular emotional assessment and efficient management in order to increase patient satisfaction. Future studies with larger samples are necessary for more accurate statistical analysis. To optimize patient care, a multidisciplinary healthcare team is recommended.

Cross-cultural adaptation and psychometric properties of patient-reported outcome measures in Arabic speaking countries: A scoping review

BACKGROUND

Patient-reported outcome measures (PROMs) are increasingly recognized as an indicator of healthcare quality and safety. Over the past decades, there has been a growing interest in using PROMs in Arabic-speaking populations. However, there is a paucity of data regarding the quality of their cross-cultural adaptation (CCA) and measurement properties.

OBJECTIVES

To identify PROMs that have been developed, validated or cross-culturally adapted to Arabic and evaluate methodological qualities of CCA and measurement properties.

METHODS

MEDLINE, EMBASE, CINAHL, PsycINFO, IPA, and ISI Web of Science were searched using search terms 'PROMs', 'Arabic countries', 'CCA', and 'psychometric properties'. Measurement properties were evaluated using COSMIN quality criteria and CCA quality was assessed using the Oliveria rating method.

RESULTS

This review included 260 studies with 317 PROMs, focusing on psychometric testing (83.8%), CCA (75.8%), utilizing PROMs as outcome measures (13.4%), and developing PROMs (2.3%). Out of the 201 cross-culturally adapted PROMs, forward translation was the most frequently reported component of CCA (n = 178), followed by back translation (n = 174). Out of the 235 PROMs that reported measurement properties, internal consistency was the most frequently reported measurement property (n = 214), followed by reliability (n = 160) and hypotheses testing (n = 143). Other measurement properties were less reported, including responsiveness (n = 36), criterion validity (n = 22), measurement error (n = 12), and cross-cultural validity (n = 10). The strongest measurement property was hypotheses testing (n = 143), followed by reliability (n = 132).

CONCLUSION

There are several caveats regarding the quality of CCA and measurement properties of PROMs included in this review. Only 1 out of 317 Arabic PROMs met CCA and psychometric optimal quality criteria. Therefore, there is a need to improve the methodological quality of CCA and measurement properties of PROMs. This review provides valuable information for researchers and clinicians when choosing PROMs for practice and research. There were only 5 treatment-specific PROMs, indicating the necessity for more research focusing on development and CCA of such measures.

Quality of life in Vietnamese young adults: A validation analysis of the World Health Organization's quality of life (WHOQOL-BREF) instrument

BACKGROUND

The abbreviated version of the World Health Organization's Quality of Life (WHOQOL-BREF) instrument has been widely used to assess the quality of life (QOL) of different population groups.

AIMS

This study aimed to examine the validity and reliability of the Vietnamese version of WHOQOL-BREF in evaluating the QOL of Vietnamese young adults.

METHODS

The WHOQOL-BREF was validated in an online cross-sectional study among 445 young adults from 16 to 35 years in Vietnam. The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to examine the factorial structure of the instrument. The reliability and validity of the new factorial model were evaluated.

RESULTS

The EFA and CFA suggested the 3-factor model had better fit models than the theoretical 4-factor model. The internal consistency of factor 1 "External life" and factor 2 "Internal life" were excellent (0.931) and good (0.864), respectively, while the internal consistency of factor 3 "Physical and mental health" was nearly acceptable (0.690). Results indicated that the 3-factor model had good convergent and divergent validity as well as moderate discriminant validity. Scores of factors "External life" and "Internal life" had significant predictive effects on general QOL, general health, and overall QOL (p < 0.05). Meanwhile, factor 3 "Physical and mental health" could only predict general health and overall QOL (p < 0.05).

CONCLUSION

This validation study improves understanding of the characteristics of QOL among young adults in Vietnam. While the theoretical model of WHO can be utilized for global comparisons, a new local model should be considered and cross-culturally adapted to successfully capture the progress of public health interventions for promoting young adults' QOL.

Quality of life among Syrian refugees in Germany: a cross-sectional pilot study

Background

More than 10 million Syrians have left their homes and sought refuge in neighboring countries, including Europe, since the beginning of the Syrian conflict in March 2011, and immigration continues to this day. This cross-sectional study included Syrian refugees residing in and around Hannover, Germany. We investigated whether general socioeconomic factors (e.g. age, sex, housing, asylum duration) were predictive factors for the quality of life (QOL) of Syrian refugees in Germany.

Methods

The QOL of Syrian refugees was assessed using the WHOQOL-BREF tool, a questionnaire assessing the QOL in four domains: Physical health, psychological, social relationships and environment. A total of 114 Syrian refugees, aged between 18 and 45 years, who obtained one of the following statuses, asylum, refugee protection or subsidiary protection, were included. The QOL domain and total scores of Syrian refugees in Germany were compared with a Western norm and Sub-Saharan population. Data were analyzed with the Spearman Rho correlation coefficient, Kruskal–Wallis and Mann–Whitney U test and multivariate linear regression.

Results

More than 65% of the participants (62.3% male, 37.7% female) were between 18 and 29 years old, and 45% had lived in Germany for less than four years. The lowest QOL score was reported in the social relationship’s domain (60.5%), while the psychological score was lowest in participants aged 40–45 years (P = 0.011). The age was significantly negatively associated with physical health (P = 0.010), psychological (P <  0.001) and the total QOL (P = 0.005). Asylum duration was associated with the environment domain (P = 0.040), the short-time refugees were less satisfied than the longtime refugees, and with aspects of the psychological domain in Enjoying life and Concentration ability (P <  0.001 and P = 0.033, respectively), yet was not associated with total QOL or total domain scores. There were significant associations between housing and the psychological domain (P = 0.032) and housing and the social relationship domain (P <  0.001). The refugees who living in camps registered a lower score in psychological than residents of apartments and houses, and the single refugees had a higher score than those married and divorced (P = 0.032 and P = 0.035, respectively).

Conclusions

The Syrian refugees participating in this study showed a low QOL score in the assessment of all domains compared to the normal population, especially regarding social relations and psychological; it was associated with socioeconomic factors, such as housing, asylum duration and marital status. This calls for urgent societal and political efforts to strengthen the social living conditions of Syrian refugees in Germany.

Cultural adaptation and validation of the Sidamic version of the World Health Organization Quality-of-Life-Bref Scale measuring the quality of life of women with severe preeclampsia in southern Ethiopia, 2020

Background

Women with severe preeclampsia often present with more health complaints compared to those with uncomplicated pregnancies. Estimating the quality of life of women affected with severe preeclampsia could provide direction for further interventions. However, the current measurement of the quality of life has not been culturally adapted and validated for this population. This study aimed to translate, culturally adapt, and test the reliability and validity of the World Health Organization Quality-of-Life-Bref Scale (WHOQOL-BREF) in southern Ethiopia among women with severe preeclampsia.

Methods

An institutional-based cross-sectional study was conducted in southern Ethiopia in selected hospitals with randomly recruited women with severe preeclampsia. Cultural adaptation and validation techniques were used to translate and adapt the WHOQOL-BREF scale. Face, content validity, forward and backward translations, and synthesis were computed using an expert panel. The scale was pretested and adjusted accordingly. Internal consistency (Cronbach’s alpha) and test–retest reliability (Intraclass Correlation Coefficient = ICC) were examined. Confirmatory factor analysis (CFA) was computed to test the fit of the structure to the local setting before conducting exploratory factor analysis (EFA). Multiple methods for determining the number of factors extracted (scree test, eigenvalues) were used. We compared the original English structure with the new structure in the study setting and extracted a new structure using EFA.

Results

The internal consistency reliabilities ranged from 0.8045 to 0.9123 indicating good-to-excellent reliability. The item‑level content validity ranged from 0.86 to 1.00; the scale‑level content validity index was 0.97. In CFA, the model fit indices were unacceptable (Comparative Fit Index (CFI = 0.87), Root Mean Square Error of Approximation (RMSEA = 0.23), Standardized Root Mean Square Residual (SRMR = 0.38), Tucker Lewis Index (TLI = 0.85) and (PCLOSE = 0.00). Three new factor structures were extracted using EFA for current research with a total variance was 91%.

Conclusions

The failure of the original scale in this study population highlights the importance of culturally adapting tool to local settings. EFA confirmed a three-factor structure, inconsistent with the original English structure.

Health-related quality of life of refugees: a systematic review of studies using the WHOQOL-Bref instrument in general and clinical refugee populations in the community setting

Purpose

To systematically review studies on HRQOL, measured by the WHOQOL-Bref instrument, of refugees in general and clinical populations who are settled in the community of the hosting country, and outline the differences in scores among the two population groups and across the four domains of WHOQOL-Bref (physical, psychological, social relationships and environment domain) as well as factors impacting those outcomes.

Methods

Several databases were systematically searched by using a broad search strategy. Additionally, a hand search for grey literature was performed. Studies had to comply with the following inclusion criteria: (a) population of refugees; (b) living in the community of the country of destination; (c) assessing HRQOL through the WHOQOL-Bref instrument.

Results

15 studies were identified and divided into two subgroups: (a) general population of refugees (b) clinical population of refugees, who were specifically selected for their mental status or because they had experienced relevant past traumas. Although we can outline common patterns among the two groups, in terms of domains scoring the highest and the lowest, heterogeneous values of HRQOL are observed across the studies included.

Conclusions

Individuals who were included in the clinical refugee group have a lower quality of life in respect to the general population of refugees. However, among the two groups different patterns can be outlined considering each domain of HRQOL: higher scores for the Physical and lower for the Environment domain when considering the general population of refugees and higher scores for the Environment and lower for the Psychological domain when referring to the clinical one. These lower scores are probably due to having a higher rate of mental distress and being more exposed to somatization, stigmatization and barriers to access the healthcare system of the hosting country.

Exploring correlates of depression, quality of life and alcohol misuse: a nationwide cross-sectional study of international migrants during the COVID-19 epidemic in China

OBJECTIVES

The COVID-19 pandemic has overwhelmed health systems globally. With the increase of global migration, quantifying the health needs and key correlates of these outcomes is a global health priority. This study assessed migration characteristics, COVID-19 attitudes and the postmigration social environment as key correlates of depression, quality of life and alcohol misuse among international migrants in China.

DESIGN

A nationwide cross-sectional online survey was conducted from 17 February and 1 March 2020.

SETTING

Links to the online survey were disseminated by migrant-focused community-based organisations through WeChat.

PARTICIPANTS

English speaking international migrants who met the inclusion criteria. Inclusion criteria were being born in a country outside of China, aged 18 years or over, cumulatively living in China for 1 month or more and staying in China between December 2019 and February 2020.

OUTCOME MEASURES

Depression, quality of life and alcohol misuse.

RESULTS

Regression models indicated that planning or considering leaving China due to COVID-19, lacking the confidence to protect themselves and not being confident that the epidemic would end soon was associated with greater depression, lower quality of life and greater levels of alcohol misuse. Worry about contracting COVID-19 and feeling helpless to prevent infection were associated with greater depression and lower quality of life. General perceived social support, and trust in Chinese people, institutions and systems were protective factors for depression and associated with higher reported quality of life.

CONCLUSIONS

This study identifies key correlates that, if adequately addressed through public health outreach, may safeguard migrant well-being during a public health emergency. Trust in people and systems within the postmigration environment is an important consideration for future public health planning efforts.

Post-migration well-being of Sub-Saharan Africans in China: a nationwide cross-sectional survey

PURPOSE

This study aims to understand the quality of life (QOL) among Sub-Saharan African (SSA) migrants and explore the factors that contribute to and shape SSA migrants' QOL and shed light on how post-migration factors affect their QOL in China.

METHODS

We conducted a nationwide cross-sectional survey on QOL of SSA migrants in China from August, 2019 to November, 2019. We recruited SSA migrants using a combination of peer-referred online and offline surveys. The WHOQOL-BREF scale assessed the QOL of participants, and depressive symptoms were measured using Center for Epidemiologic Studies-Depression scale. Correlates of well-being including depressive symptoms, migration-related factors, and socio-demographic characteristics were included in hierarchical linear regression models to explore the contributions of these factors on QOL of SSA migrants.

RESULTS

This study included 928 eligible SSA migrants. The total score of the WHOQOL-BREF scale was 66.8 ± 14.0. Attitudes of local people toward SSA migrants (β = 3.1, 95% CI 2.4, 3.0) and satisfaction with their living conditions (β = 3.6, 95% CI 2.5, 4.7) were positively associated with QOL and explained 12.2% of the variance. Contracting an infectious disease in the past year (β = - 5.3, 95% CI - 7.6, - 2.9) and depression werenegatively associated with QOL (β = - 0.7, 95% CI - 0.7, - 0.6) and explained 24.4% of the variance.

CONCLUSION

Our study underscores the importance of several key factors that may aid in the improvement of QOL among SSA migrants. Post-migration environmental factors emerged as key correlates of QOL, which builds on previous evidence that the post-migration context should be improved to safeguard the well-being of SSA migrants in China.

Systematic review of factors associated with quality of life of asylum seekers and refugees in high-income countries

The stressful experiences that many asylum seekers and refugees (AS&R) are exposed to during forced migration, and during resettlement in host countries, can have a profound impact on their mental health. Comparatively less research attention has been allocated to exploring other indices of quality of life (QoL) in AS&R populations. This review aimed to (i) synthesize the predictors and correlates of QoL of AS&R populations in high-income countries, and (ii) to identify the methodological strengths and weaknesses of this body of research. Fourteen databases were systematically searched (Medline, PsychINFO, CINAHL, Cochrane Library, Health Technology Assessment, National Health Service Economic Evaluation, Educational Resource Index and Abstracts, BiblioMap, Scopus, Social Sciences Citation Index, Evidence Aid, DARE, Web of Science and PubMed). Eligibility criteria included: adults seeking asylum or refuge in a high-income country, primary quantitative data, the use of a measure based on the WHO's definition of QoL, published in a peer-reviewed journal. A narrative synthesis approach was used, and the quality was assessed using the AXIS tool for cross-sectional studies and the CASP tool for longitudinal studies. Of the 13.656 papers identified, 23 met the eligibility criteria. A wide range of factors were found to have significant associations with QoL. Both positive and negative correlates of QoL were largely dominated by social (e.g. social networks) and mental health factors (e.g. depression). Although all of the cross-sectional studies met over half of the quality criteria, only 12 met 75% or more of these criteria. For the longitudinal studies, for all but one study lacked statistical precision and the results cannot be applied to the local population. Key findings across the various forms of QoL (overall, physical, psychological, social and environmental) were that having established social networks and social integration were associated with higher QoL, whereas having mental disorders (i.e. PTSD or depression) was strongly associated with reduced QoL. More research is needed into physical and environmental predictors and correlates of QoL. The findings of the review can be used to inform policies and interventions aimed at supporting AS&R and promoting the integration and wellbeing of these populations.

Psychometric evaluation of the modified 19-item Bengali version of WHOQOL scale using Rasch analysis: a cross-sectional study of a rural district in Bangladesh

BACKGROUND

This investigation aims to validate the psychometric properties of the modified 19-item Bengali version World Health Organization Quality of Life (WHOQOL) instrument in a typical healthy rural population in Bangladesh.

METHOD

The cross-sectional investigation collected 300 adults aged 18-85 years from Narail, a rural district of Bangladesh using a multi-stage cluster random sampling technique. Face-to-face interviews were conducted between July and August 2018 using an Android phone installed with a mobile data collection application CommCare. SPSS version 25; IBM. and a Rasch analysis software RUMM2030 were used for analyses.

RESULTS

Results showed good overall fit, as indicated by a significant item-trait interaction with Bonferroni corrected p values, for physical ([Formula: see text] =32.13, p = 0.041), psychological ([Formula: see text] =14.93, p = 0.529), social ([Formula: see text] =12.62, p = 0.397), and environmental ([Formula: see text] =22.01, p = 0.339) domains. Item fit residual (IFR) values for all domains were within the desired limits, indicating no deviation from the expected relationship between the individual items and the rest of the items of the scale. Person fit residual (PFR) values also showed no person misfit among the samples, indicating item threshold are suitable for Rasch analysis. Reliability of the three domains of the 19-item WHOQOL scale was very good as indicated by a person separation index (PSI) = 0.873 and Cronbach's Alpha (CA) = 0.881 for physical domain, PSI = 0.739 and CA = 0.746 for psychological domain, and PSI = 0.753 and CA = 0.781 for environmental domain. The social domain (PSI = 0.650 and CA = 0.669) had below acceptable reliability. All items in each domain had ordered thresholds except one item of the environmental domain. All four domains of the 19-item WHOQOL scale showed unidimensionality and was free from local dependency. Each domain also showed similar functioning for adults and older adults, males and females, no education and at least primary level of education, low and high socio-economic conditions.

CONCLUSION

The 19-item modified WHOQOL scale is confirmed as an efficient screening tool for measuring QoL among healthy rural Bangladeshi people. The scale could be implemented more widely. In particular, validations are required for diseases-specific population in Bangladesh to measure the Health Related Quality of life (HR-QoL) assessments for people suffering from chronic or other diseases.

Psychometric evaluation of an interview-administered version of the WHOQOL-BREF questionnaire for use in a cross-sectional study of a rural district in Bangladesh: an application of Rasch analysis

BACKGROUND

This study aimed to validate the psychometric properties of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) questionnaire for use in a rural district of Bangladesh.

METHODS

This cross-sectional study recruited a multi-stage cluster random sample of 2425 participants from the rural district Narail of Bangladesh in May-July 2017. Rasch analysis was carried out using the sampled participants, as well as multiple validation random sub-samples of 300 participants, to validate four domains of the WHOQOL-BREF questionnaire: physical, psychological, social and environmental.

RESULTS

The original WHOQOL-BREF appeared to be a poor fit for both sampled and sub-sampled group of participants in Narail district in all underlying domains: physical, psychological, social and environmental. Two items (sleep and work capacity) from the physical domain, two items (personal belief and negative feelings) from the psychological domain and three items (home environment, health care and transport) from the environment domain were excluded for goodness of fit of the Rasch model. The social domain exhibited reasonably reliable fitness while fulfilling all the assumptions of the Rasch model. A modified version of the WHOQOL-BREF questionnaire using five-items for the physical ([Formula: see text] = 36.47, p = 0.013, Person Separation Index (PSI) = 0.773), four-items for the psychological ([Formula: see text] = 28.30, p = 0.029, PSI = 0.708) and five-items for the environmental ([Formula: see text] = 36.97, p = 0.011, PSI = 0.804) domain was applied, which showed adequate internal consistency, reliability, unidimensionality, and similar functioning for different age-sex distributions.

CONCLUSIONS

The modified WHOQOL-BREF questionnaire translated into Bengali language appeared to be a valid tool for measuring quality of life in a typical rural district in Bangladesh. Despite some limitations of the modified WHOQOL-BREF questionnaire, further application of Rasch analysis using this version or an improved one in other representative rural areas of Bangladesh is recommended to assess the external validity of the outcomes of this study and to determine the efficacy of this tool to measure the quality of life at the national rural level.

Use of a Modified DANP-mV Model to Improve Quality of Life in Rural Residents: The Empirical Case of Xingshisi Village, China

Climate change-related anomalies have increased public concern regarding environmental protection. This has opened newer rural development avenues. In this regard, livability of villages is crucial; it can be evaluated based on the villagers’ quality of life (QoL). The WHOQOL-BREF, a comprehensive cross-cultural and cross-disciplinary scale proposed by the World Health Organization to assess QoL, has aided in assessing and improving QoL in different regions. However, the factors of this instrument are mutually influential, necessitating an improvement strategy considering the entire system. This problem may be resolved using the DANP-mV model. However, the traditional DANP-mV model includes many items and responding to all of them is difficult for experts. Therefore, by using the case of Xingshisi Village in China, this study proposed a modified DANP-mV model to provide additional suggestions for systematic improvement of the QoL and livability in the village. Xingshisi is a model village built according to an aspirational benchmark; however, different from the traditional definition of a benchmark, this village exhibits room for improvement. Although the modified model reduces the number of questions from 650 to 168, its effect remains similar to that of the traditional model. Moreover, in the modified model, physical capacity (D₁) presented the largest dimensional gap. The interaction among the factors indicated that considering the effect of the environment (D₄) and developing a systematic improvement strategy are necessary to improve the livability of villages facing limited resources.

Validation and reliability of the Abbreviated World Health Organization Quality of Life Instrument (WHOQOL-BREF) in the hospitalized trauma population

INTRODUCTION

While the number of trauma patients surviving their injury increase, it is important to measure Quality of Life (QoL). The Abbreviated World Health Organization Quality of Life (WHOQOL-BREF) questionnaire can be used to assess QoL. However, its psychometric properties in trauma patients are unknown and therefore, we aimed to investigate the validity and reliability of the WHOQOL-BREF for the hospitalized trauma population.

METHODS

Data were derived from the Brabant Injury Outcome Surveillance. Floor and ceiling effects and missing values of the WHOQOL-BREF were examined. Confirmatory factor analysis (CFA) was performed to examine the underlying 4 dimensions (i.e. physical, psychological, social and environmental) of the questionnaire. Cronbach's alpha (CA) was calculated to determine internal consistency. In total, 42 hypotheses were formulated to determine construct validity and 6 hypotheses were created to determine discriminant validity. To determine construct validity, Spearman's correlations were calculated between the WHOQOL-BREF and the EuroQol-five-dimension-3-level questionnaire, the Health Utility Index Mark 2 and 3, the Hospital Anxiety and Depression Scale and the Impact of Event Scale. Discriminant validity between patients with minor injuries (i.e. Injury Severity Score (ISS)≤8) and moderate/severe injuries (i.e. ISS ≥ 9) was examined by conducting Mann-Whitney-U-tests.

RESULTS

In total, 202 patients (median 63y) participated in this study with a median of 32 days (interquartile range 29-37) post-trauma. The WHOQOL-BREF showed no problematic floor and ceiling effects. The CFA revealed a moderate model fit. The domains showed good internal consistency, with the exception of the social domain. All individual items and domain scores of the WHOQOL-BREF showed nearly symmetrical distributions since mean scores were close to median scores, except of the 'general health' item. The highest percentage of missing values was found on the 'sexual activity' item (i.e. 19.3%). The WHOQOL-BREF showed moderate construct and discriminant validity since in both cases, 67% of the hypotheses were confirmed.

CONCLUSION

The present study provides support for using the WHOQOL-BREF for the hospitalized trauma population since the questionnaire appears to be valid and reliable. The WHOQOL-BREF can be used to assess QoL in a heterogeneous group of hospitalized trauma patients accurately.

Psychological distress and quality of life: rationale and protocol of a prospective cohort study in a rural district in Bangaladesh

INTRODUCTION

A significant proportion of the global burden of disease has been attributed to mental and behavioural disorders. People with mental disorders (MDs) have lower levels of health-related quality of life than those without MDs. Several studies have shown that in low-resource countries, a range of social determinants including poor health literacy is critical in the epidemiological transition of disease outcome. There is a lack of evidence of MDs literacy, the prevalence and risk factors of common mental health conditions, or any validated instruments to measure psychological distress or evaluate the quality of life in rural areas of Bangladesh.

AIMS

The aims of this study are: (1) report the awareness, knowledge, attitudes and practice (KAP) of MDs; (2) estimate the prevalence of and risk factors for psychological distress; (3) measure association of psychological distress and other socio-demographic factors with quality of life and (4) test the feasibility to use Kessler 10-item (K10) and WHO Quality Of Life-BREF (WHOQOL-BREF) questionnaires in rural Bangladesh for measuring psychological distress and quality of life.

METHODS AND ANALYSIS

A sample of 1500 adults aged 18-59 years and 1200 older adults aged 60-90 years will be interviewed from a multistage cluster random sample. Each participant will go through a face-to-face interview to assess their awareness and KAP of MDs. Information about the participant's sociodemographic and socioeconomic status will be collected along with the psychological distress (K10) and quality of life (WHOQOL-BREF) questionnaires. Internal consistency, validity, reliability and item discrimination of K10 and WHOQOL-BREF instruments will be determined by using Rasch analysis and regression techniques.

ETHICS AND DISSEMINATION

Human Ethics Approval was received from the Swinburne University of Technology Human Ethics Committee. Results of this research will be disseminated via scientific forums including peer-reviewed publications and presentations at national and international conferences.
