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

Area of Science:

• Mental Health
• Primary Care Research
• Psychotherapy Effectiveness

Background:

• Depressive disorders are frequently managed in primary care settings.
• Integrated behavioral health services enhance access to evidence-based treatments like cognitive behavioral therapy (CBT).
• Limited data exists on CBT's effectiveness for depression within primary care.

Purpose of the Study:

• To evaluate the effectiveness of cognitive behavioral therapy (CBT) for individuals with depressive disorders receiving care in a primary care setting.
• To assess symptom reduction and treatment outcomes for depression and anxiety in primary care patients undergoing CBT.

Main Methods:

• A cohort of 1,302 participants with primary depressive disorder were referred by primary care providers.
• 435 participants with moderate to severe depression engaged in at least one CBT session.
• Data on demographics, clinical characteristics, and treatment outcomes were collected via a psychotherapy tracking database.

Main Results:

• Participants with moderate to severe depression showed significant decreases in depression and anxiety symptoms post-CBT (p ≤ .001, d = 0.52–0.78).
• Reliable change, response, and remission rates varied between major and persistent depressive disorders.
• Specific CBT intervention types influenced outcomes differently across depressive disorder subtypes.

Conclusions:

• Short-term CBT in primary care settings led to significant symptom reduction for depression and anxiety.
• CBT is feasible within primary care, demonstrating its benefit for patients with depression.
• Integrated psychological services in primary care support population-based mental health care models.
