The adaptation of the Triangular Relationship Inventory into Turkish: the study of validity and reliability for university students

Abstract

Objective: The Triangular Relationship Inventory (TRI) assesses different configurations of family triangulation. The current study investigated the psychometric properties of the TRI to disseminate the familiarity of the family-of-origin variables in Turkey for the researchers and practitioners. Methods: The current sample composed of young adults; three hundred and eighty-seven university students completed the measures of TRI, Intergenerational Triangulation Subscale (INTRI), and Marlowe-Crowne Social Desirability Scale (MCSDS). First and high-order confirmatory factor analysis (CFA) was conducted to confirm the TRI's four-factor structure. Results: The first-order CFA findings indicated mediocre evidence for the four-factor structure, but the scapegoat was only the subscale that was significantly not loaded to the higher-order CFA model. Moreover, the scapegoating construct produced no significant correlations with INTRI in convergent validity. Measurement invariance, Cronbach's alpha, McDonald's Omega coefficients, and test-retest reliability were further examined. Discussion: The results revealed that TRI is useable in the Turkish sample. The four-factor structure of the scale needed to be reconsidered in Turkish culture.
