Cross-Cultural Adaptation of the General Functioning Subscale of the McMaster Family Assessment Device
Abstract Background: The aim of the study was to conduct a cross-cultural adaptation and validation of the General Functioning Subscale (GF12) of the McMaster Family Assessment Device (FAD) into the Malay language. Methods: The translation and adaptation procedure of the Malay GF12 was based on the dual-panel methodology. This involved conducting a bilingual panel (providing the initial translation into Malay language) followed by a lay panel (where items are assessed for comprehension and acceptability). A mixed-methods approach with exploratory sequential study design was employed.Results: Two hundred and fifty-one families who have children in pre-schools (Tadikas) answered the Malay GF12. The KMO value for sampling adequacy was 0.81, indicating the sample was adequate for factor analysis. The Malay GF12 demonstrated high internal consistency (Cronbach’s alpha coefficient > 0.80). In the confirmatory factor analysis, the original 12-item model did not fit very well. Alternatively, a 2-factor-6-item model showed a sufficient fit. The two constructs comprised Positive Items and Negative Items. Conclusions: The results indicate the feasibility of administering 6 of the 12 items of Malay GF12 (3 positively worded and 3 negatively worded) to measure family functioning in the Malaysian population.
