Assessing Executive and Community Functioning Among Homeless Persons with Substance Use Disorders Using the Executive Function Performance Test

This study investigates the utility of an occupational therapy assessment of executive and performance functioning and indicators of community adjustment among adults with histories of homelessness and substance abuse. A sample of 60 individuals living in a supported housing programme was interviewed about community living experiences and was assessed using the Executive Function Performance Test (EFPT). A descriptive and correlational study design was used. Measurable levels of cognitive and task impairment were documented, in older adults, non-US citizens and those diagnosed with cognitive impairments. Those who had completed a supported education/employment programme (Total EFPT t?=?-2.83, 0.008) performed better as did those who were employed (Total EFPT t?=?-2.33, 0.03), met regularly with their case managers (cooking t?=?-2.07, 0.04), had hobbies (paying bills r?=?-0.31, 0.02) and had longer periods of abstinence (organization/planning t?=?-3.59, 0.001). Limitations of the study include the unanticipated need by the clients for additional translation services. Future directions include a randomized controlled intervention study using the EFPT. An implication of this study for occupational therapists working with homeless clients who abuse substances is the importance of assessing and treating their cognitive impairments as well as providing these services within housing first agencies.
