Abstract

Background and objectives: The population of older people is increasing across the world. Older people need care and support from their families to be able to live independently. This study aimed to design and evaluate the psychometric properties of the family support for older people (FSOP) questionnaire.

Methods: In this instrument development study using a mixed-methods design, the psychometric properties of the FSOP questionnaire in terms of validity and reliability were evaluated.

Results: The FSOP questionnaire consisted of 50 items in six domains. It was shown to have appropriate qualitative and quantitative validities (score > 1.5). The indicators of content validity (CVR > 0.62, ICVI ≥ 0.80, and SCVI > 0.94) and confirmatory factor analysis (indexes of χ2/df = 2.50, CFI = 0.96, GFI = 0.97, AGFI = 0.96, NNFI = 0.96, PNFI = 0.89, TLI = 0.96, and RMSEA = 0.06) were satisfactory. Cronbach's alpha coefficient for reliability was 0.94, indicating an optimal score.

Conclusions: Healthcare providers and family caregivers are suggested to use the FSOP questionnaire for improving the quality of life of older people at home.
