"One Size Doesn't Fit All": Design Considerations for an Exercise Program to Improve Physical Function in Older Veterans with Serious Mental Illness.

Older adults with serious mental illness (SMI) (i.e., schizophrenia, schizoaffective disorder, bipolar disorder) have compromised physical function that adversely affects their quality of life. Exercise is an effective intervention to improve function in older persons; however, older people with SMI experience barriers to exercise engagement. This study sought to obtain feedback on an exercise program in development for older people with SMI that comprised home-based exercise delivery, individualized exercise prescription, and motivational health coaching calls. Individual interviews and focus groups were conducted with older Veterans with SMI ( n = 3) and clinical staff serving this population (directors: n = 3; clinicians: n = 15, k = 3) to elicit feedback on the perceived feasibility and acceptability of the preliminary program and recommendations for modifications to the program. Rapid analysis was used to summarize transcripts of audio-recorded interviews and focus groups. Results indicated a strong perceived feasibility and acceptability of the preliminary intervention because of how the individualized exercise prescription component (i.e., exercise plan) would be personalized to the Veteran's preferences and abilities. Clinical staff participants expressed concerns about how the lack of real-time supervision would negatively affect exercise completion. Participants recommended tailoring the home-based exercise delivery and motivational health coaching calls components to each Veteran's unique context.
