Establishing the feasibility and preliminary efficacy of a health belief model based educational training program on health belief perceptions and dementia‐preventive behaviors in people with type 2 diabetes

Abstract

AbstractThis quasi‐experimental study evaluated feasibility and preliminary efficacy of dementia‐preventive educational training intervention program based on the health belief model for improving perceived health beliefs and dementia‐preventive behaviors among people with type 2 diabetes mellitus. Two community hospitals with 72 eligible participants were chosen from 12 local institutions using simple random sampling method. One hospital (22 patients) was allocated to dementia‐preventive educational training intervention, and the other hospital (23 patients) was allocated to control intervention (using simple random sampling). Primary study outcome was feasibility, and secondary outcomes were changes in dementia prevention behaviors and health belief perceptions. Recruitment rate was 62.5% (45/72) and 22 patients in each group totally completed outcome measures and attended sessions, indicating feasibility of the intervention and study design. There were no significant differences between groups at baseline. After training, participants in the intervention group had significantly higher scores than control group in prevention behaviors and perceptions of health beliefs. The intervention group experienced significant with‐group changes in outcomes. Results show that conducting a subsequent fully powered experimental study is feasible, and the intervention has promising efficacy.
