Questionnaire and demographic data were analyzed using numbers, percentages, dependent and independent groups t-tests, correlation analysis.
Results: The AAMQ-13-TR has a Cronbach's alpha ( α ) score of 0.90 ( p  < 0.001). It has a split-half reliability coefficient of 0.86. The confirmatory factor analysis (CFA) shows that the factor structure of the AAMQ-13-TR agrees well with the two-factor model of the original questionnaire.
