The Effects of the Modified Transtheoretical Theory of Stress and Coping (TTSC) Program on Dementia Caregivers' Knowledge, Burden, and Quality of Life.

This quasi-experimental study aimed to examine the effect of the modified transtheoretical theory of stress and coping (TTSC) program on the knowledge, burden, and quality of life of dementia caregivers. The participants comprised 60 caregivers (30 participants in each group) selected via purposive sampling, and the study was conducted between October 2018 and September 2019 in a semi-urban area of central Thailand. The experimental group received an 8-week program, while the comparison group received routine care. A self-administered questionnaire was used to collect data. To analyze the intervention's effectiveness, repeat measure ANOVA and Mann-Whitney, Friedman, and Dunn's tests were performed. At the end of the program and again three months after the end of the program, the knowledge and quality of life scores for the experimental group were significantly higher ( < 0.05 and < 0.05, respectively) than for the control group. The burden score decreased in the experimental group and increased in the control group in week 8 ( < 0.05). There was no statistically significant difference between the groups, as demonstrated by ANOVA (F[1.58] = 2.394; = 0.127). Our findings show that this program had a positive effect on the caregivers' knowledge and quality of life. However, the program did not affect the caregivers' burden.
