Psychometric Properties of the Family Quality of Life Scale in Greek Families with Intellectual Disabilities

Abstract In recent years intellectual disability has changed from the individual quality of life to an evaluation of the quality concerning the whole family. The aims of the present study were to examine the psychometric properties of the Greek version of Family Quality of Life Scale (FQoL). A total of 180 caregivers of people with intellectual disabilities participated in the current study. The participants were all informal caregivers of adults with disabilities and comorbidities (other chronic diseases), belonging to the intimate family context (cousins, uncles, neighbours, professional in-home caregivers, neighbours, etc.). The Beach Center Family Quality of Life Scale (FQoL) was administered twice, with a 7 day interval to 44 eligible caregivers. Factor analysis yielded a three-factor solution, explaining explaining 71.63 % of the total variance. Cronbach alpha for the three factors were between 0.883 to 0.960. Construct validity showed a high correlation between FQoL factors and APGAR scores. More specifically high correlations were found between “Family interaction and support” (r = 0.855), “Family care” (r = 0.630), “Disability related support” (r = 0.683) and APGAR scores (p < 0.0005 respectively). The test/retest reliability indicated that the scales scores were remarkably consistent between the two occasions. The current results support that the Greek version of FQoL is a measure with satisfactory psychometric properties, ...
