Psychometric evaluation of the Greek version of Mc Master Family Assessment Device (FAD)

Abstract

Introduction

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 to the Greek language but never validated.

Aims and objectives

To evaluate the psychometric properties of the Greek version of FAD in a non-clinical sample.

Methods

In a sample of Greek families, FAD was administered together with the already validated Family Adaptability and Cohesion Evaluation Scale (FACES-III). In a subsample of 96 participants, the scales were administered again after 1 month.

Results

A sample of 453 participants (194 children and 259 parents) had completed both questionnaires (151 families). Mean age of children was 23.62 (SD: 6.35), 68 (35%) were males. Mean age of parents was 51.4 (SD: 8.2), 117 (45.2%) males. All subscales of FAD had significant correlation (concurrent validity) with FACES-III (n = 453, P < 0.001). Test-retest reliability range from 0.58 to 0.82 (n = 96, P < 0.001). Internal consistency (Cronbach's alpha) range from 0.47 to 0.94. A model with the 6 factors had a good statistical fit but not all the items were loading in the same components as from the theory assumed.

Conclusions

The Greek FAD has good psychometric properties, although its factor structure might differ from the original version. Further evaluation of the Greek version of FAD in other settings and in different samples especially clinical remains a task for future research.
