Significant disparities in access to mental health care exist in the current mental health system; integrated primary care (IPC) offers an alternative model of service delivery with initial evidence for reducing disparities. Little is known about whether, and how, IPC reduces barriers to mental health services. Here we report on a set of three studies using mixed methodology to explore the perceptions of potential recipients of care regarding barriers to accessing mental health treatment by setting (IPC or specialty mental health [SMH]) and ethnicity (Latinx or non-Latinx White). In Study 1, a main effect of setting indicated IPC patients perceived fewer barriers to accessing IPC than SMH. A setting by ethnicity interaction revealed Latinx patients perceived greater barriers to SMH than non-Latinx White patients. In Study 2, data from qualitative interviews suggested IPC patients found behavioral health treatment in IPC to be accessible and satisfactory. In Study 3, a non-treatment-seeking sample did not endorse a difference in barriers by setting or ethnicity. Overall, it appears IPC patients perceive behavioral health treatment delivered in primary care to be satisfactory, beneficial, and successful in reaching individuals with mental health need who otherwise may not receive care. Non-treatment-seeking individuals with lower psychiatric distress did not identify a difference in barriers between IPC and SMH settings. Findings are consistent with the potential of the IPC setting for reducing barriers to care, although key elements of IPC may need to be addressed to increase acceptability across all population subgroups.
