Measurement of perceived social support among people with dementia: a validation of the Indonesian version of the personal resource questionnaire-2000 (PRQ2000-INA)
摘要
Perceived social support has been shown to play a crucial role in the well-being of dementia patients, potentially reducing the burden of symptoms and enhancing quality of life. However, there is limited research on perceived social support in dementia populations, particularly in low- and middle-income countries. This study aims to validate the Indonesian version of the Personal Resource Questionnaire (PRQ2000-INA) for measuring perceived social support in people with mild to moderate dementia.
MethodsA cross-sectional study was conducted involving 105 participants diagnosed with mild to moderate dementia at the Memory Clinic of Dr. Sardjito General Hospital in Yogyakarta, Indonesia. The PRQ2000-INA, a 15-item self-administered questionnaire, was translated and culturally adapted following international guidelines. Confirmatory Factor Analysis (CFA) using Structural Equation Modeling (SEM) was conducted to assess the construct validity and reliability.
ResultsThe age range of the participants was 62 years, with a total of 64 males and 41 females. The PRQ2000-INA demonstrated strong construct validity, with high factor loadings (> 0.7) and and satisfactory fit indices (RMSEA = 0.045, CFI = 0.988, SRMR = 0.029). The reliability was excellent, with composite reliability 0.97 (> 0.7). No significant differences in perceived social support were observed across demographic variables such as age, gender, and educational level.
ConclusionThe PRQ2000-INA is a reliable and valid tool for measuring perceived social support in people with mild to moderate dementia in Indonesia. Further research is recommended to explore the concurrent validity of the PRQ2000-INA and its use in predicting social support in dementia populations.
