Background: Staff caregivers of day care centers provide many activities for older people. However, there is a lack of a systematic curriculum based on Taiwanese culture to improve cognitive function, self-care ability, and depressive mood status in these individuals.

Purpose: This study was designed to test the effectiveness of a series of localized cognitive stimulation training courses implemented by direct caregivers and aimed at improving cognitive function, self-care ability, and depressive mood in older people at day care centers.

Methods: This cluster-randomized controlled trial research was conducted over a four-month period. The participants were randomly assigned to the experimental, comparison, or control groups based on their day care center affiliation. The experimental group received a series of localized cognitive stimulation training sessions with musical rhythm courses from day care center direct caregivers. The cognitive function, self-care ability, and depression mood state of the three groups were then tested.

Results: The experimental group reported statistically significant changes in average scores for attention, feeding, and depressive mood. After controlling for time and degree of participation in activities, the comparison group reported a lower average score for cognitive function at timepoint 3. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The results of this study support caregivers at day care centers implementing a series of localized cognitive stimulation training course interventions to prevent declines in activities of daily living and cognitive function and ameliorate depressive mood in older adults. In the future, a larger sample size should be used to improve the effectiveness of the intervention.
