Psychological well-being for cognitively impaired people scale: assessing reliability and validity of Turkish version

Abstract

Purpose: The aim of the present study was to evaluate the psychometric properties of the Psychological WellBeing of Cognitively Impaired People (PWB-CIP) scale in people with dementia in nursing homes. Method: It was conducted with 70 people with dementia and 12 formal caregivers in two nursing homes. This study used translation and back translation for the scale's language equivalence and expert opinion for content validity. The reliability and validity were tested by exploratory and confirmatory factor analysis, test-retest correlation analyses, and internal consistency. Results: The PWB-CIP was clustered under two factors. Cronbach's alpha scores for positive affect (alpha = 0.624), and negative affect (alpha = 0.822) factors were satisfactory. Confirmatory factor analysis revealed an acceptable level of fit (GFI = 0.905, p < 0.001, CFI = 0.94, RMSEA = 0.067). The test, retests were positively correlated (r: 0.756, p < 0.001). Conclusion: The 9-item PWB-CIP is a valid and reliable instrument for the examined Turkish sample. The PWBCIP demonstrated robust psychometric properties in the context of nursing homes, indicating its suitability for assessing the well-being of individuals with dementia. Nursing implications: The validated PWB-CIP can serve as a valuable tool for nurses and caregivers in evaluating the psychological well-being of cognitively impaired individuals in nursing home settings, enabling targeted interventions to enhance their overall quality of life.
