A single-blinded, parallel-groups (intervention, active and passive control groups) randomized controlled trial (RCT) was chosen to investigate whether a specific reminiscence program is associated with higher levels of quality of life in nursing home residents with dementia.
The intervention used a life-story approach, while the control groups participated in casual discussions. The Social Engagement Scale (SES) and Self Reported Quality of Life Scale (SRQoL) were used as the outcome measures, which were examined at baseline (T0), 12 weeks (T1), and six months (T2) after the intervention. The final sample had 135 subjects (active control group = 45; passive control group = 45; intervention group = 45).
The Wilcoxon test showed significant differences in the intervention group between T2
, and between T1
in the SES, and there were significant differences between T0
(intervention effect size = 0.267) and T1
(intervention effect size = 0.450) in the SRQoL. The univariate logistic regression scores showed that predictors of change in the SRQoL were associated with fewer baseline anxiety symptoms and lower depression scores.
The intervention led to significant differences between the three groups over time, showing a significant improvement in the quality of life and engagement of the residents in the intervention group.
