Abstract

After evaluating the language validity and content validity of the questionnaire, internal consistency, split-half reliability, and construct validity were examined. 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.
