The aim of the present study was to examine the psychometric properties of the Greek version of Family Adaptability and Cohesion Evaluation Scales IV (FACES IV) Package. The original FACES IV displays a six-factor structure with two balanced scales—Balanced Cohesion and Balanced Flexibility—and four unbalanced scales—Disengaged, Enmeshed, Rigid, and Chaotic—and has been shown to have satisfactory internal and test–retest reliability. A total of 584 family members agreed to participate in the study. The findings indicated that the Greek version displays similar factor structure to the original version. Cronbach’s α coefficients for the six scales ranged from .59 to .79. The test–retest correlation coefficients ranged between .94 and .97. The Family Communication Scale and the Family Satisfaction Scale demonstrated high internal consistency and test–retest reliability. Thus, the Greek version of the FACES IV Package appears to be a valid and reliable instrument to be used in both research and clinical assessment of family functioning.
