Investigating the Psychometric properties of the Family Attachment and Changeability Index (FACI8) In Iranian Society

This study aims to investigate the psychometric properties of the Persian version of the Family Attachment and Changeability Index (FACI8).

The sample group included 313 male and female participants (age range 12 to 71), who were selected using the available sampling method. The Persian version of the Scale was applied with Connor- Davidson Resilience Scale and Cohen et al.'s Perceived Tension Questionnaire. Confirmatory factor analysis and convergent and divergent validity were applied to evaluate the validity of the scale and Cronbach's alpha was used to evaluate its Internal Consistency Reliability. For examining the Test-Retest Reliability, the scale was performed on 35 subjects and Pearson correlation was used to measure it.

The results of confirmatory factor analysis indicated the fit and desirability of the two-factor model. Significant correlations between the factors of the Scale with of Resilience Scale and Perceived Tension also confirmed the divergent and convergent validity of this scale. The reliability of the scale using Cronbach's alpha coefficient calculation for the whole scale is 0.87 and the test-retest correlation coefficient of 0.9 Obtained.

In general, it can be said that the Persian version of the Family Attachment and Changeability Index, which has two factors (attachment, changeability), has a factor structure similar to the original version of the scale and has the necessary validity and reliability to use in psychological research in the Iranian sample.
