Abstract
AIM: To evaluate the psychometric properties of the Stigma Impact Scale in a global sample of people living with dementia. METHOD: Data from 710 people living with dementia were submitted for psychometric analysis. Reliability was assessed using Cronbach’s alpha. Convergent validity was assessed using correlations between the SIS two measures, the Warwick-Edinburgh mental Well-being Scale (WEMWBS) and the Dementia Quality of Life instrument (DQoL). An exploratory factor analysis and confirmatory factor analysis were used to evaluate the factor structure of the SIS. Global fit indices were used to determine goodness of fit. Endorsement ratings for each SIS item were calculated to give a descriptive understanding of the overall relevance of item level concepts for people living with dementia. RESULTS: The SIS and subscales had ‘good’ to ‘excellent’ internal consistency. The validity correlations were not in the predicted direction further no significant correlations were noted between the SIS and the WEMWBS and weak significant positive correlations were found between the SIS and DQoL. There were marginal improvements in global fit indices when comparing the model based on observed data to the theoretical model however none of the indices surpassed the cut-offs to indicate goodness of fit. The final proposed model had three factors: rejection and secrecy, loneliness and belonging and perceived social isolation. The SIS items were heavily endorsed by people living with dementia. CONCLUSION: The SIS is the most vigorously tested psychometric instrument measuring selfstigma in dementia. The SIS has good to excellent reliability and is heavily endorsed by people living with dementia, however future work is required to improve the factor structure of SIS. Further the results of the validity testing pose a number of theoretical and empirical questions for future research.
