Cognitive behavioral therapy for depressive disorders: Outcomes from a multi-state, multi-site primary care practice.

BACKGROUND: Individuals with depressive disorders often present to and seek treatment in primary care. Integrated behavioral health services within this setting can improve access to evidence-based cognitive behavioral therapy (CBT). However, limited information exists on the effectiveness of CBT for depression in primary care. METHODS: Of the 1,302 participants with a primary depressive disorder referred by their primary care provider, 435 endorsed moderate to severe depression at baseline and engaged in at least one CBT session. A psychotherapy tracking database was used to collect relevant data, which included demographics, clinical characteristics, treatment outcomes, and CBT intervention use. RESULTS: Participants with moderate to severe depression who participated in CBT reported a significant decrease in depression and anxiety symptoms at the end of treatment (p ≤ .001, d = 0.52-0.78). Rates of reliable change, response, and remission and types of CBT interventions used differed between major and persistent depressive disorders. LIMITATIONS: Multiple limitations must be noted, which are related to the naturalistic study design, inclusion and exclusion criteria, sample operationalization, symptomatic measurement, time-limited and focused assessment, data collection strategies, and psychological services. Together, these temper the conclusions that can be drawn. CONCLUSION: Significant reductions in depression and anxiety symptoms were reported by participants with depressive disorders who engaged in short-term CBT within primary care. This study indicates that CBT can be implemented within primary care and suggests that primary care patients with depression can benefit from integrated psychological services, supporting population-based models of care.

Cognitive Behavioral Therapy for Anxiety Disorders: Outcomes From a Multi-State, Multi-Site Primary Care Practice.

BACKGROUND: Anxiety disorders are among the most common mental health conditions. Individuals with anxiety typically seek services in primary, rather than specialty, care. While there is significant evidence supporting the efficacy and effectiveness of cognitive behavioral therapy (CBT) for anxiety disorders, there have been no naturalistic studies reporting anxiety-specific treatment outcomes in primary care. METHODS: Participants (N = 1,589) were recruited from a multi-state, multi-site primary care practice, with 491 participants endorsing moderate to severe anxiety at baseline and engaging in at least one CBT session. Data was drawn from a psychotherapy tracking database. RESULTS: Among participants with moderate to severe anxiety who engaged in CBT, a significant decrease in anxiety and depression symptoms was observed over the course of psychotherapy (p< .001, d = 0.57-0.95). Rates of reliable change, response, and remission varied across diagnostic categories. The use of CBT interventions also varied across diagnoses in line with evidence-based treatment recommendations. DISCUSSION: Short-term CBT delivered in primary care is associated with significant improvements in anxiety and depression symptoms among participants with anxiety disorders. These findings support the use of a population-based approach to anxiety disorders treatment and suggest that evidence-based CBT can be implemented in the real-world setting.
