Abstract
In this study, it was aimed to make the validity and reliability study of the Mental Vulnerability Questionnaire (MVQ) in the Turkish community. Data were collected from 722 participants (51.25% women, 48.75% men), aged 18-68 (M = 34.52, SD = 11.34). For construct validity Confirmatory factor analysis (CFA) was conducted using a tetrachoric correlation matrix and Diagonal Weighted Least Squares (DWLS) method. The bifactor model showed the best fit (χ²/df = 1.11, CFI = 0.99, RMSEA = 0.012, SRMR = 0.048, TLI = 0.99). For convergent validity Mentalization Scale (MS) was used,and for incremental validity Brief Symptom Inventory (BSI) and the Eysenck Personality Questionnaire Short Form (EPQ-SF) were used. As a result of multiple regression analysis it was found that all MVQ subscales predicted depression, anxiety, somatization, and obsessive symptoms. As a result of test-retest the correlations were found to be in range of 0.69 to 0.88. Kuder Richardson-20 (KR-20) coefficients were calculated for internal consistency and the values were determined between 0.60 to 0.86. In split-half reliability analysis (Spearman-Brown) the coefficients were found between 0.61 to 0.77. In conclusion, it was determined that the MVQ is a valid and reliable tool to measure the mental vulnerability in the Turkish community.
