Cross-cultural translation and adaptation of the Dementia Public Stigma Scale
ABSTRACT
Background:
The Dementia Public Stigma Scale (DPSS) is a brief, user-friendly tool for assessing public stigma related to dementia. It has not been previously used or validated in China. The aim of this study was to translate, adapt, and validate the DPSS for use in Chinese populations, ensuring its cultural relevance and psychometric properties.
Objective:
The aim of this study was to translate, adapt, and validate the DPSS for use in Chinese populations, ensuring its cultural relevance and psychometric properties.
Methods:
The DPSS was translated into Chinese, followed by testing for translation equivalence and content validity. The adapted scale was administered to 314 participants. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to examine the factor structure of the scale. Internal consistency and test-retest reliability were assessed to evaluate the reliability of the scale.
Results:
The Chinese version of the DPSS demonstrated strong validity with a Kaiser-Meyer-Olkin (KMO) value of 0.840, and the chi-square for the factor model was significant (χ² = 499.475, df = 120, p = 0.000), indicating good factor structure. The scale explained 67.679% of the cumulative variance. CFA results indicated an adequate model fit, with a Tucker-Lewis Index (TLI) of 0.86, Comparative Fit Index (CFI) of 0.89, and a Root Mean Square Error of Approximation (RMSEA) of 0.08. Internal consistency, as measured by Cronbach’s alpha, ranged from 0.682 to 0.865, and test-retest reliability was strong (α = 0.789 to 0.885).
Conclusions:
The Chinese version of the DPSS is both valid and reliable for assessing dementia-related stigma in Chinese populations. It provides a useful tool for researchers and healthcare professionals in China to understand and address dementia stigma, facilitating public health initiatives and awareness campaigns.
