Home-based Exercise for SMI

VA Office of Research and Development

Overview

Older Veterans with serious mental illness (schizophrenia, schizoaffective disorder, bipolar disorder) have reduced physical function (endurance, strength, mobility) that leads to lower quality of life. Exercise interventions are effective at improving physical function and could have a tremendous impact on this population. Despite the established benefits of exercise, there has been little work focused on improving multiple aspects of physical function in older Veterans with serious mental illness. The purpose of this study is to examine the feasibility and acceptability of a home-based exercise program for older Veterans with serious mental illness.

Older Veterans with serious mental illness (schizophrenia, schizoaffective disorder, bipolar disorder) have significantly compromised physical function that leads to heightened rates of falls, hospitalizations, nursing home admissions, as well as early mortality. In fact, this population's physical function is compromised across multiple domains including mobility, endurance, and strength. Exercise is effective for increasing all domains of physical function (i.e., mobility, endurance, strength) in older Veterans. But, environmental difficulties (e.g., lack of transportation), low motivation, and medical issues affecting older Veterans with serious mental illness contribute to low engagement rates and high dropout rates in facility-based exercise programs. Individualized home-based exercise programs, which are safe and effective for older Veterans with health challenges, could address the main barriers to exercise in older Veterans with serious mental illness by promoting greater accessibility and individual tailoring. The purpose of this study is to evaluate the feasibility and acceptability of a 12-week home-based exercise program for older Veterans with serious mental illness.

Time frame: End of intervention (12 weeks)

Feasibility/Acceptability as measured by coaching call session fidelity

Percentage of administered coaching calls with a fidelity rating of at least adequate (80% is benchmark)

Time frame: End of intervention (12 weeks)

Feasibility/Acceptability as measured by Client Satisfaction Questionnaire Total Score

Total score on the Client Satisfaction Questionnaire (CSQ-8), which is an 8-item measure with each item scored from 1-4 with higher scores representing greater acceptability of the intervention and the range of total scores spanning 8-32 (24 is benchmark).
