Validation of the Lithuanian version of the Eating Disorder Examination Questionnaire 6.0 in a student sample.

ABSTRACT: BACKGROUND AND OBJECTIVES:The Eating Disorder Examination Questionnaire 6.0 (EDE-Q 6.0) is one of the most broadly used self-report tools that assesses attitudes and behaviors associated with eating disorders (EDs). The aim of the present study was to examine the reliability, validity, and factor structure of the Lithuanian version of the EDE-Q 6.0 (LT-EDE-Q 6.0) in a nonclinical student sample. MATERIALS AND METHODS:A sample of 382 students (mean age 24.0 ± 6.4) participated in the study. The students completed a self-report questionnaire measuring the risk of EDs (LT-EDE-Q 6.0), body image (LT-MBSRQ-AS), quality of life (LT-WHOQOL-BREF), and self-esteem (RSES). Cronbach's alpha assessed the internal consistency of the EDE-Q 6.0. Pearson's correlations were used for the analyses of the construct and concurrent validity with the subscales of LT-MBSRQ-AS, LT-WHOQOL-BREF, and RSES. Intraclass correlation coefficients (ICC) were calculated for assessing test-retest reliability. RESULTS:The mean score of the LT-EDE-Q 6.0 in the mixed sample was 1.5 ± 1.02. For women and men, the general mean scores were higher than in the majority of the samples of Western Europe but lower than in the United States. Acceptable internal consistency for the four subscales (0.75-0.88) and the LT-EDE-Q 6.0 general score (0.94) was obtained. Test-retest reliability was good to excellent for all subscales (0.66-0.91) and for the items that assessed essential behavioral features of EDs (0.84-0.90, except item 14 ICC = 0.4). The LT-EDE-Q 6.0 scores had adequate concurrent validity. However, the original 4-factor structure or other proposed models of EDE-Q were not obtained by CFA. CONCLUSIONS:The results of the current study support the applicability, validity, and reliability of the LT-EDE-Q 6.0 in a nonclinical Lithuanian student sample. However, we recommend assessing the general scale score without the application of the subscales. The Lithuanian version of this instrument should be further investigated with clinical samples to identify clinically diagnosed cases.

Project description:BackgroundThe Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder Questionnaire- 7 (GAD-7) are short screening instruments used for detection of depression and anxiety symptoms in various settings, including general and mental health care as well as the general population. The aim of this study is to evaluate psychometric properties and factorial structure of the PHQ-9 and the GAD-7 in a sample of Lithuanian university students.Methods1368 students (mean age 22.5±4.8) completed the PHQ-9 and the GAD-7 questionnaires online; after the completion of the survey, students were asked to provide phone contact for an additional interview. Eligible students were approached later by trained interviewers and completed The Clinical Interview Schedule-Revised for assessment of depressive and anxiety disorders.ResultsResults showed that the PHQ-9 and the GAD-7 are reliable screening tools for depression and anxiety (Cronbach alpha 0.86 and 0.91, respectively). The one-factor structure of the PHQ-9 and the GAD-7 was confirmed by the Confirmatory Factor Analysis. A cut-off of ≥10 for the PHQ-9 resulted in 71% sensitivity and 66% specificity recognizing students with increased risk for mood or anxiety disorder. For the GAD-7, a cut-off ≥9 resulted in 73% sensitivity and 70% specificity recognizing students at risk. The PHQ-9 was sensitive but not specific in recognizing students with depressive disorders. The sensitivity and specificity of the GAD-7 in differentiating students with generalized anxiety disorders were low.ConclusionsThe PHQ-9 and the GAD-7 have sufficient formal psychometric properties, but their clinical utility as diagnostic tools for recognition of depressive and anxiety disorders in students is limited. Due to low specificity and high false positive rates, both scales are recommended only as an initial screening tool for recognition of subjects with increased risk of mental disorders, however positive cases should be later assessed using more comprehensive instruments.

Project description:Findings from studies investigating cognitive flexibility in eating disorders (EDs) are inconsistent, and although neuropsychological tests are commonly used to measure these skills, they may not be particularly effective in predicting everyday functioning. Also, extant studies have largely focused on flexibility in anorexia nervosa (AN), with assessments targeting general rather than specific flexibility, and cognitive, rather than behavioral flexibility. Knowledge regarding ED specific flexibility and flexibility in bulimia nervosa (BN) and binge eating disorder (BED) is still scarce. The aim of this study was to develop and validate a novel measure assessing general and ED specific flexibility in a diagnostically diverse sample, and in healthy controls (HCs). A sample of 207 adult individuals with EDs (55% AN, 29% BN, 16% BED) and 288 HCs responded to an online, 51-item, pilot questionnaire on ED specific and general flexibility. In addition, participants completed the shift subscale from the Behavior Rating Inventory of Executive Function Adult version (BRIEF-A), and the Eating Disorder Diagnostic Scale (EDDS). A principal component analysis (PCA) in the clinical sample yielded a 36-item, three-factor solution capturing general flexibility, flexibility related to food and exercise, and flexibility concerning body shape and weight. Results showed that the measure had good to excellent internal consistency, and good convergent validity. A confirmatory factor analysis (CFA) using data from HCs revealed good fit indexes, supporting the original factor solution. A receiver operating characteristics analysis (ROC) demonstrated excellent accuracy in distinguishing scores from those with and without EDs. A cutoff score of 136 yielded the most balanced sensitivity and specificity. Significant differences in general and ED specific flexibility were found between individuals with and without EDs. Overall, HCs achieved the highest flexibility scores, followed by those with BED, BN, and AN. In sum this novel measure, the Eating Disorder Flexibility Index (EDFLIX) questionnaire, was found to be reliable and valid in the assessment of cognitive and behavioral flexibility, with results offering support for the conceptual distinction between general and ED related flexibility. The study also provides strong evidence for the discriminant validity of the EDFLIX with results revealing significant differences in flexibility in people with and without EDs. In addition, significant differences in flexibility also emerged when comparing diagnostic groups, indicating the utility of the assessment instrument for classification purposes.
