Psychometric properties and validation of the Italian version of the Family Assessment Measure Third Edition - Short Version - in a nonclinical sample

Family functioning plays an important role in developing and maintaining dysfunctional behaviors, especially during adolescence. The lack of indicators of family functioning, as determinants of personal and interpersonal problems, represents an obstacle to the activities aimed at developing preventive and intervention strategies. The Process Model of Family Functioning provides a conceptual framework organizing and integrating various concepts into a comprehensive family assessment; this model underlines that through the process of task accomplishment, each family meets objectives central to its life as a group. The Family Assessment Measure Third Edition (FAM III), based on the Process Model of Family Functioning, is among the most frequently used self-report instruments to measure family functioning. The present study aimed to evaluate the psychometric properties of the Italian version of the Family Assessment Measure Third Edition - Short Version (Brief FAM-III). It consists of three modules: General Scale, which evaluates the family as a system; Dyadic Relationships Scale, which examines how each family member perceives his/her relationship with another member; and Self-Rating Scale, which indicates how each family member is perceived within the nucleus. The developed Brief FAM-III together with the Family Assessment Device were administered to 484 subjects, members of 162 Italian families, formed of 162 fathers aged between 35 and 73 years; 162 mothers aged between 34 and 69 years; and 160 children aged between 12 and 35 years. Correlation, paired-sample -test, and reliability analyses were carried out. General item analysis shows good indices of reliability with Cronbach's α coefficients equal to 0.96. The Brief FAM-III has satisfactory internal consistency, with Cronbach's α equal to 0.90 for General Scale, 0.94 for Dyadic Relationships Scale, and 0.88 for the Self-Rating Scale. The Brief FAM-III can be a psychometrically reliable and valid measure for the assessment of family strengths and weaknesses within Italian contexts. The instrument can be used to obtain an overall idea of family functioning, for the purposes of preliminary screening, and for monitoring family functioning over time or during treatment.
