Factor analytic support for the EDE-Q7 among American Indian/Alaska Native undergraduate women

OBJECTIVE

American Indian/Alaska Native (AI/AN) people have historically been excluded from eating disorder research. Consequently, not much is known about the validity of eating disorder assessment measures in this group. The purpose of the current study was to examine the factor structure of a short measure for eating pathology, the seven-item Eating Disorder Examination Questionnaire (EDE-Q7), in AI/AN undergraduate women. Exploratory analyses examined the measurement invariance of the EDE-Q7 across AI/AN, White, and Latinx undergraduates.

METHODS

A sample of 150 AI/AN undergraduate women completed the full EDE-Q (28 items) as part of two larger studies. The seven items comprising the EDE-Q7 were selected from the full measure to test the factor structure. Random samples of White and Latinx women of equal sample size were chosen from the larger studies to test measurement invariance.

RESULTS

Confirmatory factor analyses found support for the EDE-Q7 factor structure in AI/AN undergraduate women, and scores were strongly positively correlated with the original EDE-Q global scale and disordered eating behaviors. Exploratory analyses found support for the measurement invariance of the EDE-Q7 across AI/AN, White, and Latinx women. One-way ANOVAs showed no significant racial and ethnic differences on the EDE-Q7.

DISCUSSION

The current study found psychometric support for the EDE-Q7 in AI/AN undergraduate women and provided preliminary evidence that the EDE-Q7 can be meaningfully compared across AI/AN, White, and Latinx undergraduate women. Further research should continue to investigate the EDE-Q7 and other eating disorder measures in AI/AN and other historically excluded groups.

Depression, Anxiety and Eating Disorder-Related Impairment: Moderators in Female Adolescents and Young Adults

Adolescents and young adults, particularly females, are highly vulnerable to the development of anxiety disorders, depression, and eating disorders. Comorbid anxiety disorder or depression in eating disorders are associated with greater symptom severity, poorer prognosis, and burden of illness. Nonetheless, studies on what affects the relationship between anxiety, depression, and eating disorders in female at-risk samples are scarce. Using hierarchical linear modeling, the present study examined potential moderators to explain between-person differences in the association between anxiety, depression, and eating disorder-related impairment within 12- to 25-year-old females (N = 320). High impairment in anxiety/depression was associated with more severe eating disorder symptoms. Older age as well as greater impairment in mood dysregulation, self-esteem, and perfectionism were linked to more severe eating disorder symptomatology. Whereas mood dysregulation, self-esteem, and perfectionism had no statistically significant moderating effects, younger age appeared to augment the association of anxiety/depression and eating disorder symptomatology. Preventive care in particular needs to consider age-related effects as eating disorder symptoms are associated more strongly with symptoms of anxiety and depression in early adolescence.

Cross-cultural adaptation and psychometric properties of the Brazilian-Portuguese version of the Organizational Readiness for Implementing Change questionnaire

OBJECTIVE

The assessment of the degree to which health professionals, workers and organizations are ready to implement changes in health services deserves special attention, especially related to new technologies, public policies and innovation. The objectives of this study were to conduct a Brazilian Portuguese Brazil cross-cultural adaptation of the ORIC questionnaire and to initiate the study of its psychometric properties.

METHODS

Through a cross-sectional study, the Organizational Readiness for Implementing Change (ORIC) questionnaire, containing 12 questions, was translated and later applied to a sample of workers from traditional primary health care units undergoing transformation to family health units. Statistical analysis included Cronbach's alpha, exploratory and confirmatory factor analysis by structural equation model using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist.

RESULTS

Workers from ten health units participated in the study (n = 150). The analysis confirmed two main factors (Effectiveness and Commitment) with Eigenvalues > 1. Rotation by the orthogonal method showed that the instrument questions confirmed the factors analyzed by the original instrument. The total Cronbach's Alpha of ORIC was 0.94, showing excellent reliability.

CONCLUSION

The Brazilian Portuguese Brazil version of the ORIC-Br questionnaire showed good psychometric properties and can be used in health services to measure organizational readiness, considered as an indicator of the potential success in implementing change.

New Horizons in Measurement: a Review of Novel and Innovative Approaches to Eating-Disorder Assessment

PURPOSE OF REVIEW

Eating disorders are serious mental-health concerns that will affect over 30 million individuals in the USA at some point in their lives. Eating disorders occur across the lifespan, in a variety of ethnicities and races, in both men and women, and across the socioeconomic spectrum. Given the prevalence and severity of eating disorders, it is important that clinicians and researchers have access to appropriate assessment tools to aid in the early identification and treatment referral, differential diagnosis, treatment planning, and progress monitoring, and to ensure valid research findings. In this review, we describe novel and innovative assessment tools that were developed within the past 5 years for utilization in research and/or clinical practice with individuals with eating disorders.

RECENT FINDINGS

We identified six multidimensional assessments for eating disorders, all of which can be administered online (with some also offering paper-and-pencil versions). Strengths of the measures included good internal consistency, test-retest reliability, and convergent validity. However, in part, due to problematic scale construction methods, certain scales had poor discriminant validity and most were developed and validated in mostly female samples. There are promising new eating disorder measures from which to choose; however, many measures continue to be limited by poor discriminant validity and need additional validation prior to incorporation into routine research and clinical practice.

Adherence to Web-Based Self-Assessments in Long-Term Direct-to-Patient Research: Two-Year Study of Multiple Sclerosis Patients

Background

Direct-to-patient research via Web-based questionnaires is increasingly being used. Missed data or delayed reporting of data may negatively affect the quality of study results. It is insufficiently known to what degree patients adhere to agreed self-assessment schedule over the long term and whether questionnaires are filled out in a timely manner.

Objective

The objective of this study was to investigate patients’ adherence to a self-assessment schedule with low-frequency long questionnaires versus that with a high-frequency short questionnaire.

Methods

In this study, the 36-item MS Impact Profile (MSIP) questionnaire measured (perceived) disabilities and the 54-item MS Quality of Life-54 (MSQoL-54) questionnaire measured health-related quality of life at 6-month intervals. Additionally, the 2-item Medication and Adherence (MA) questionnaire documented medication and adherence to disease-modifying medication every month. An experienced MS nurse assessed the Expanded Disability Status Scale (EDSS) score via phone. For both the self-assessment schedules, we calculated the percentage of patients who had completed all the questionnaires in the first 2 years (completion adherence), the percentage of patients who completed all the questionnaires within set time frames (interval adherence), the relationship between adherence and the EDSS score, and the timing of EDSS assessment.

Results

Of the 331 patients who enrolled themselves, 301 patients completed at least one questionnaire. At month six (M6), M12, M18, and M24, the MSIP was completed by 83.4% (251/301), 71.8% (216/301), 68.1% (205/301), and 58.5% (176/301) of the patients, respectively; the MSQoL-54 by 82.1% (247/301), 71.8% (216/301), 66.8% (201/301), and 57.1% (172/301), respectively; and the MA questionnaire by 80.1% (241/301), 70.4% (212/301), 62.1% (187/301), and 53.5% (161/301), respectively. For the MSIP, 56.8% (171/301) of the patients were 2-year completion adherent; 55.5% (167/301) and 53.5% (161/301) of the patients were completion adherent for the MSQoL-54 and MA questionnaires, respectively. Whereas 85.5% (142/166) of the patients were interval adherent for the MSIP and MSQoL-54, 25.5% (41/161) were interval adherent for the MA questionnaire, with 73.9% (119/161) exceeding the maximum MA monthly interassessment interval. Completion adherence for the monthly short MA questionnaire was higher in patients with moderately high disability (EDSS 5.0-5.5) than for those with no or minimal disability (EDSS 0-2.5) (OR 5.47, 95% CI 1.08-27.69; P=.040). Completion adherence was also higher in patients with EDSS assessment within 6 months after baseline than in those with later assessment (OR 1.810, 95% CI 0.999-3.280; P=.050).

Conclusions

The 2-year completion adherence to Web-based self-assessments did not differ between the low-frequency long questionnaires and a high-frequency short questionnaire, but the interval adherence was substantially higher for the low-frequency long questionnaires. Personal contact with a member of the research team regarding a clinically relevant professional-reported outcome early in the study might positively affect the long-term completion adherence in direct-to-patient studies.

Dental Management Survey Brazil (DMS-BR): creation and validation of a management instrument

Questionnaires for the assessment of knowledge and self-perception can be useful to diagnose what a dentist knows about management and administration. The aim of the present study was to create and validate the Dental Management Survey Brazil (DMS-BR) scale, based on meetings with experts in the field. After having elaborated the first version, 10 audits were performed in dental offices in order to produce the final version, which included nine dimensions: location, patient, finance, marketing, competition, quality, staff, career, and productivity. The accuracy of the instrument was measured by intrarater and interrater reliability. In the validation phase, 247 Brazilian dentists answered a web-based questionnaire. The data were processed using Stata 13.0 and the significance level was set at 95%. The instrument had intrarater and interrater reliability (ICC-0.93 and 0.94). The overall average of respondents for the DMS-BR scale was 3.77 (SD = 0.45). Skewness and kurtosis were below absolute values 3 and 7, respectively. Internal validity measured by Cronbach's alpha was 0.925 and the correlation of each dimension with the final result of the DMS-BR ranged between 0.606 and 0.810. Correlation with the job satisfaction scale was 0.661. The SEM data ranged between 0.80 and 0.56. The questionnaire presented satisfactory indicators of dentists' self-perception about management and administration activities.
