Turkish Adaptation and Psychometric Evaluation of the Family Relationship Assessment Scale (FRAS)

This study aimed to adapt the Family Relationship Assessment Scale (FRAS) to the Turkish cultural context and to examine its psychometric properties. The study sample consisted of 329 participants (246 women and 83 men) aged between 18 and 59 years, including university students and community members. For test–retest reliability, the scale was administered to 58 psychology students twice with a three-week interval. Convergent validity was examined in a subsample of 111 participants using the Multidimensional Scale of Perceived Social Support (MSPSS), Family Role Performance Scale (FRPS), Family Harmony Scale (FHS), and Healthy Family Scale (HFS). Results indicated strong internal consistency, with Cronbach’s alpha coefficients ranging from .82 to .94, and item–total correlations ranging from .54 to .86. Test–retest reliability coefficients ranged between .74 and .84. Convergent validity analyses showed significant correlations between FRAS subscales and related family functioning measures, although some correlations were non-significant. Confirmatory factor analysis supported the 15-item three-factor structure of the scale. Overall, the findings provide preliminary evidence supporting the reliability and validity of the Turkish version of the FRAS in a non-clinical sample. The scale may serve as a useful tool for future research examining family relationships in the Turkish context.
