Initial and Follow-Up Evaluations of Integrated Psychological Services for Anxiety and Depression in a Safety Net...

Despite the recognized importance of integrated behavioral health, particularly in safety net primary care, its effectiveness in real world settings has not been extensively evaluated. This article presents 2 successive studies examining the effectiveness of integrated behavioral care in a safety net setting.

Study 1 compared the depression and anxiety scores of predominately low-income and minority patients who underwent brief interventions (N = 147) to those of patients from a demographically similar comparison clinic without integrated psychological services, matched on baseline levels of anxiety and depression and length of time between assessments (N = 139). Study 2 did not include a control group but served as a long-term follow-up assessment of anxiety and depression for a subset of 47 patients who finished treatment and could be reached by telephone within 6-18 months of their last session.

Study 1 found that patients from the clinic with integrated psychology services experienced greater decreases in depression and anxiety scores than patients in the control clinic. These effects did not differ as a function of age, gender, or race. Study 2 found that patients continued to decline in depression and anxiety over time, with lower scores at the last session and even lower scores after longer-term follow-up ranging from 6 to18 months. These improvements remained significant when controlling for other interim mental health treatments.

These results support the short- and long-term treatment effects of brief primary care behavioral interventions, further strengthening the case for integrated behavioral healthcare in safety net settings.
