Relations between subjective well-being and Alzheimer’s disease: A systematic review

ABSTRACT. Subjective Well-Being (SWB) is determined by the degree of satisfaction with one's own life and the intensity/frequency with which we experience negative and positive emotions. Current studies indicate that SWB is beneficial for health. Objective: The aim of this systematic review was to analyze the methodological quality of published articles on SWB in people with Alzheimer’s disease (AD). Methods: The keywords “Well-Being” and “Alzheimer” were used. Inclusion criteria were a) articles with a sample of the elderly population; b) empirical articles; c) articles published between 2014 and 2019. Analysis of the selected articles was performed using the Downs and Black Checklist. Results: 13 articles were selected for further analysis. The results showed that only one of the articles reached a high methodological quality level. The other articles had an average level, ranging from 46% to 67%, of total protocol compliance. Conclusion: The studies analyzed had a medium level of methodological quality. It is important to improve the methodological quality of studies on SWB in people with AD.
