PSYCHOMETRIC PROPERTIES OF THE SCALE OF CONSTRUCTIVE STRATEGIES OF THE COPING BEHAVIOR DIAGNOSTIC TECHNIQUE

Background. The problem of coping behavior diagnostics is of particular interest due to the requirements of modern psychometrics. At the moment, diagnostic methods of this construct with reasonable psychometric characteristics are lacking in clinical practice. Purpose. The research purpose was to analyze the psychometric properties of the scale of constructive strategies of the coping behavior questionnaire based on the Rasch model. Material and methods. A total of 270 respondents were assessed with the help of the coping behavior diagnostic technique. The difficulty of the scale items was calculated. The construct validity of the scale was assessed. The reliability and separation statistics values were determined. Results. The scale item difficulty measures ranged from -1.04 to 1.20 logits. The UMS and WMS indices had acceptable values (in the range of 0.7 – 1.3). The index of reliability was 0.81. Conclusions. The scale items of the designed questionnaire are balanced by the degree of difficulty. The construct validity of the items is sufficient. The index of reliability of the method has an acceptable significance (0.81). The using of the scale makes it possible to diagnose three levels of severity of the construct.
