The development and evaluation of a self-efficacy enhancement program for older adults with mild cognitive impairment

Objective: The aims of this study were to develop a self-efficacy enhancement program and to evaluate its effect on cognitive function, dementia knowledge, self-efficacy, depression, and dementia preventive behaviors in older adults (age >= 65 years) with mild cognitive impairment (MCI).Methods: This equivalent control group pretest-posttest study was conducted at a tertiary hospital in Seoul, South Korea. Older adults with MCI were randomly allocated to an experimental (EG, n = 16) or control group (CG, n = 16). The EG underwent an 8-week intervention (weekly 60-min session) utilizing self-efficacy enhancement strategies; the CG received usual care. The intervention was comprised of physical, cognitive, and emotional activities and was followed by 4-week maintenance during which both groups engaged in self-learning at home with a dementia preventive guidebook. Outcome data were evaluated at the pretest and 8, 10, and 12 weeks later. This study adhered to the CONSORT guidelines.Results: There were significant differences in cognitive function, dementia knowledge, self-efficacy, and dementia preventive behaviors, but not in depression between the two groups over the time. Regarding cognitive function subdomains, significant differences were observed in visuospatial/executive, attention, language, and delayed recall.Conclusion: The integrated intervention consisting of physical, cognitive, and emotional activities was effective in improving cognitive function, dementia knowledge, self-efficacy, and dementia preventive behaviors. This suggests that this program can be utilized as an educational program to prevent dementia in older adults with MCI in dementia support centers, public health centers, clinics, and hospitals.
