The Greek version of the McMaster Family Assessment Device.

The Family Assessment Device (FAD) is a self-report questionnaire, developed to assess the six dimensions of the McMaster Model of Family Functioning. It has been translated into the Greek language but never validated. We aimed to evaluate the psychometric properties of the Greek version of the FAD in a nonclinical sample. In a sample of Greek families, the FAD was administered together with the already validated Family Adaptability and Cohesion Evaluation Scale (FACES-III). In a subsample of 96 individual participants, the scales were administered again after 1 month. The sample of 453 participants (151 families: 194 children and 259 parents) completed both questionnaires. The mean age of the children was 23.62 years (SD = 6.35 years), and 68 (35%) were male. The mean age of the parents was 51.4 years (SD = 8.2 years), and 117 (45.2%) were male. All subscales of the FAD had significant correlation (concurrent validity) with the FACES-III (n = 453, p < .001). Test-retest reliability ranged from .58 to .82 (N = 96, p < .001). Internal consistency (Cronbach's alpha) ranged from .47 to .94. A model with the six factors had a good statistical fit but not all the items were loading in the same components as from the theory assumed. The Greek FAD has good psychometric properties, although its factor structure might differ from the original version.
