Integrated Primary and Behavioral Healthcare (IPBH) programs have been investigated extensively in community settings, but few studies have included the effect of such programs on college campuses. Studies that have examined the effects of IPBH in community settings have indicated that integrated care is more effective than primary care interventions alone. No studies were found examining the clinical outcome of this type of intervention in a collegiate IPBH program. The recovery curves of 267 students with severe mental health symptoms were examined in the current study using Growth Curve Modeling. Pre and post changes were also examined using repeated measures of ANOVA. Student subgroups were identified as (1) counseling-only, (2) counseling and primary care, and (3) counseling, primary care, and psychiatric care. These groups were compared to each other for differences in speed of recovery and pre to post treatment changes. Results indicated that treatment groups showed similar pre and post changes. Comparisons of treatment groups based on the speed of recovery resulted in students in the counseling-only group recovering faster than other two groups although this difference accounted for only 1.3% of the variance. These results are discussed considering the existing literature and the implications for future collegiate IPBH research and clinical practice for counselors, primary care staff, and psychiatrists.
