A Randomized Control Trial for ReDeSign: A Dementia-Friendly Mobile Microlearning Training for Store Workers in Japan
Hiroshige Matsumoto, Yasuhiro Hagiwara, Noriko Yamamoto‐Mitani, Ayumi Igarashi. The Gerontologist, 2022-12-07
Topic: Risk, prevention and care in population studies
Process evaluations confirmed satisfaction and high completion rates of the program. In total, 150 participants were included in the analysis. The intervention group showed significantly greater improvements in attitude (Hedge's g = 0.70) and knowledge (g = 0.59) after 1 month, compared to the control group. Helping behavior increased in the intervention group, although it did not differ significantly between the groups. All outcomes remained significantly improved after 4 months. DISCUSSION AND The findings provide evidence that dementia-friendly training reduces the general public's stigma and increases helping behavior in stores. Mitigation of time constraints through mobile microlearning is expected to contribute to the dissemination and help people living with dementia maintain their social participation in the communities. Clinical Trials Registration Number: UMIN000043623.
Key findings
- Process evaluations confirmed satisfaction and high completion rates of the program.
- In total, 150 participants were included in the analysis.
- The intervention group showed significantly greater improvements in attitude (Hedge's g = 0.70) and knowledge (g = 0.59) after 1 month, compared to the control group.
- Helping behavior increased in the intervention group, although it did not differ significantly between the groups.
- All outcomes remained significantly improved after 4 months.
Why it matters
In this randomized trial of 150 store workers in Japan, a dementia-friendly mobile microlearning program significantly improved attitude and knowledge after one month compared with controls, and all outcomes remained significantly improved after four months. Helping behavior increased in the intervention group but did not differ significantly between the groups, so the training may reduce stigma and increase helping behavior in stores.
