The present study examined the stability of the factor structure and psychometric properties of the complementary scales of family adaptability and cohesion evaluation scales (FA-CES) in Iranian families. The scale was translated into Persian language and was used as part of a battery of questionnaires consisting of the scales measuring family communication scale (FCS), family satisfaction scale (FSS), depression, anxiety, stress scale (DASS), youth self-report for behavior problems (YSR), parenting stress index short form (PSI-SF), and life events (LF). A sample of 1652 subjects (father=558, mother=576, child=518) from seven capital cities including Tehran, Mashhad, Tabriz, Kerman-shah, Yazd, Shiraz, and Esfahan completed questionnaires.Confirmatory factor analysis upheld the original two-factor structure. The results provided acceptable internal consistency, test-retest reliability, convergent, and divergent validity.Findings supported the Persian version of FCS and FSS for cross-cultural use as a valid and reliable measure for di-agnostic purposes in family context.
