Objective: This study evaluated the effects of the federal Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 on the use of outpatient and clinic-based mental health services and spending on those services., Methods: Data came from the 2005-2013 Medical Expenditure Panel Survey. The analytic sample included adults ages 26-64 who were continuously enrolled in employer-sponsored insurance for a calendar year (N=66,602 person-year observations). A difference-in-differences study design was used to compare changes in outcomes before and after implementation of the MHPAEA between people whose insurance plan was or was not affected by the law., Results: The federal parity law was not significantly associated with changes in the likelihood of using mental health services, the amount of mental health services used, or total or out of-pocket spending for mental health services. The law was marginally significantly associated with a shift toward more use of mental health specialty services rather than primary care services among individuals who used ambulatory mental health care., Conclusions: Consistent with other research using different study designs and data, this study found that the MHPAEA had at most small effects on patterns of mental health services use and spending through 2013. Understanding whether these effects were small because most employer-sponsored plans were already parity compliant or because plans were noncompliant with the law has major implications for mental health policy and parity enforcement.

Objective: The Mental Health Parity and Addiction Equity Act (MHPAEA) was intended to eliminate differences in insurance coverage for mental health and substance use disorder services and medical-surgical care. No studies have examined mental health service use after federal parity implementation among individuals with diagnoses of eating disorders, for whom financial access to care has often been limited. This study examined whether MHPAEA implementation was associated with changes in use of mental health services and spending in this population., Methods: Using Truven Health MarketScan data from 2007 to 2012, this study examined trends in mental health spending and intensity of use of specific mental health services (inpatient days, total outpatient visits, psychotherapy visits, and medication management visits) among individuals ages 13-64 with a diagnosis of an eating disorder (N=27,594)., Results: MHPAEA implementation was associated with a small increase in total mental health spending ($1,271.92; p<.001) and no change in out-of-pocket spending ($112.99; p=.234) in the first year after enforcement of the parity law. The law's implementation was associated with an increased number of outpatient mental health visits among users, corresponding to an additional 5.8 visits on average during the first year (p<.001). This overall increase was driven by an increase in psychotherapy use of 2.9 additional visits annually among users (p<.001)., Conclusions: MHPAEA implementation was associated with increased intensity of outpatient mental health service use among individuals with diagnoses of eating disorders but no increase in out-of-pocket expenditures, suggesting improvements in financial protection.

Integrated care holds promise for reducing mental health disparities for racial and ethnic minority groups, but studies are lacking. The authors consider critical components of effective integrated models for minority populations, including cultural and linguistic competence and a diverse workforce, and describe emerging best practices. To successfully implement integrated models into practice with minority populations will require guidance from communities, consumers and family members, and national experts.
