Development and Validation of the Family Quality of Life in Dementia (FQOL-D) Scale For Korean Sample

Abstract

The purpose of this study is to develop and test the validity of the Family Quality of Life in Dementia (FQOL-D) scale for Korean sample. The FQOL-D scale was developed in 2010 (Rose & Williams) based on the Beach Center Family Quality of Life Scale, which is the most widely used scale in the area of family quality of life research. The data used were collected from 156 dementia family caregivers in Daejeon metropolitan city and Chungcheong province. These analyses supported five-factor structure of the FQOL-D scale which consisted of 24 items. Five factors are as follows: ‘family interaction’, ‘social/emotional well-being’, ‘physical/material well-being’ ‘dementia-related support’, and ‘caring competence’. The Cronbach"s alpha estimate of the scale was .900. This scale of five-factor model exhibited acceptable fit when it was assessed by overall fit measure criteria (TLI=.886, CFI=.900, RMSEA=.067). Also, this scale met the criteria of convergent and discriminant validity. These results proved the validity of the scale. The FQOL-D scale should be useful to capture the asset and capability of individual family with dementia, and the policy impact on families with dementia.
