Association of functional disability with mental health services use and perceived unmet needs for mental health care among adults with serious mental illness.

BACKGROUND

Approximately 13.1 million U.S. adults experienced serious mental illness (SMI) in 2019. Persons with disability (PWD) have higher risks of SMI. Ensuring adequate access to mental health (MH) services for PWD is imperative to ameliorate this burden.

METHODS

Using the 2015-2019 National Survey on Drug Use and Health, we obtained study variables for U.S. adults with SMI in the past year and used multivariable logistic regression models to examine the association of disability with MH services and perceived unmet needs.

RESULTS

The sample comprised 12,532 respondents, representing 11,143,650 U.S. adults with SMI. Overall, PWD had higher proportions of using prescription medications (64.7% vs. 46.2%), outpatient treatment (48.4% vs. 36.5%) and inpatient treatment (8.6% vs. 4.7%) compared to persons without disability; however, the prevalence of perceived unmet MH service needs was also higher (46.3% vs. 39.4%) among PWD. Multivariable logistic regression models showed presence of any disability, cognitive and ≥2 limitations were significantly associated with MH services use (all p<0.01). However, PWD were significantly more likely to report perceived unmet MH service needs (p<0.01 for any disability as well as cognitive, complex activity, and ≥2 limitations).

LIMITATIONS: Due to data limitations, disability status and SMI may be misclassified for some respondents, and the results may not be generalized to all individuals with SMI.

CONCLUSION

While PWD were more likely to use MH services, they also had higher odds of unmet MH needs. These results call for more effective and tailored mental health services for PWD.
