A psychometric investigation on the diagnostic utility of the posttrauma risky behaviors questionnaire.

ABSTRACT: The Posttrauma Risky Behaviors Questionnaire (PRBQ) is a screening measure for posttrauma reckless and self-destructive behaviors (RSDBs). We examined (1) PRBQ's predictive relations with clinical (vs. not) endorsements of distinct RSDBs, and (2) PRBQ's optimal cutoff score yielding the most appropriate balance of sensitivity and specificity statistics. The sample included 354 adult trauma-exposed community participants (M_age=35.76 years; 57.90% female). Logistic regression analyses indicated that the PRBQ significantly differentiated individuals endorsing (vs. not) clinical levels of alcohol/drug misuse, disordered eating, problematic gambling, and compulsive buying. Receiver operating characteristic (ROC) curve analyses indicated that the 14-item PRBQ total score had moderate accuracy in differentiating individuals endorsing clinical vs. non-clinical levels of drug misuse, disordered eating, problematic gambling, compulsive buying, and engagement in RSDBs (PTSD's E2 Criterion); and low accuracy for alcohol misuse. ROC curve analyses indicated 3.5-6.5 as the optimal range of PRBQ cutoff scores. Thus, the PRBQ has good ability to discriminate participants endorsing (vs. not) clinical levels of alcohol/drug misuse, disordered eating, problematic gambling, and compulsive buying (lowest accuracy in identifying participants with clinical levels of alcohol misuse), and a minimum cutoff score between 3.5 and 6.5 may suggest using additional diagnostic assessments and clinical interventions.

Project description:Introduction:Brucellosis is one of the most prevalent diseases in Torbate Heidarieh, Iran; it is a common disease between human and animals. The present study aimed to review the psychometric properties of a questionnaire on brucellosis prevention behaviors based on the PRECEDE model among rural farmers and their family members (PRECEDE-QBPB). Materials and Methods:The study was a combination of qualitative and quantitative stages. In the qualitative stage, an 86-item questionnaire including interviews with 30 farmers, their family members and other effective people, as well as literature review, was designed. In the quantitative stage, psychometric properties of the PRECEDE-QBPB including the face, content, and constructs validities, as well as reliability measurement of the questionnaire were evaluated. Item impact, content validity ratio (CVR) and content validity index (CVI) for all items were calculated. Besides, confirmatory factor analysis (CFA) was done to evaluate the construct's validity; AMOS 20 was used for this purpose. In this stage, a cross-sectional study was conducted on 500 rural farmers and their family members. To estimate the internal consistency of this questionnaire, Cronbach's alpha was used for each variable. Further, descriptive statistics and Kaiser-Meyer-Olkin and Bartlett's test of sphericity were used to describe the characteristics of the participants and collect samples, respectively. Results:Based on the results of face validity and content validity (CVR, CVI and CFA 9), 19 and 22 items were removed, respectively, leaving the final questionnaire with 36 items and eight subscales including knowledge, attitude, self-efficacy, social support, enabling factors, environmental factors, behavioral factors, and reinforcing factors. The Cronbach's coefficient alpha was calculated for the total questionnaire (?= 0.92, 0.69-0.87 for subscales). The evaluation of model fit indices showed that all indices confirmed the suitability of the final model fit; therefore, the questionnaire has suitable construct validity. Conclusion:A questionnaire, as a valid tool, was designed in the present study. Healthcare providers, policymakers, planners, researchers may use this tool to find a comprehensive understanding of enabling, reinforcing, environmental and behavioral factors that affect brucellosis before implementing health education and health promotion programs.
