BACKGROUND: Individuals with severe mental illnesses (SMIs) experience anxiety that impairs functioning and quality of life. This cluster randomized trial evaluated exposure-based cognitive behavioral therapy (ebCBT) integrated into assertive community treatment (ACT) teams to reduce anxiety.
METHODS: Fifteen ACT teams were allocated to ebCBT + ACT (k = 8, n = 50) or ACT-only (k = 7, n = 43). The intervention followed four steps: situation identification, four-component analysis (behavior, cognition, emotion, physical symptoms), psychoeducation, and graded exposure. Staff received 50 h training and bimonthly supervision over 12 months. Co-primary outcomes were trait and social anxiety; secondary outcomes were psychiatric symptoms, functioning, quality of life, and recovery.
RESULTS: The ebCBT + ACT group showed significant improvements in State-Trait Anxiety Inventory-Trait scores at 12 months (AMD = -5.30, 95% CI = -8.71 to -1.90, p = 0.002, d = -0.64) and 18 months (AMD = -7.22, 95% CI = -12.1 to -2.34, p = 0.004, d = -0.60). Brief Fear of Negative Evaluation scores showed near-significant improvement at 18 months (AMD = -3.70, 95% CI = -7.44 to 0.04, p = 0.052, d = -0.40). Secondary outcomes, including global functioning, recovery, and quality of life, also improved. Cost-effectiveness analyses indicated favorable cost-effectiveness for anxiety outcomes.
CONCLUSIONS: Embedding ebCBT within ACT services may reduce anxiety-related fear and avoidance and enhance recovery-related outcomes in individuals with SMI. These findings support the feasibility and clinical value of integrating structured psychological interventions into intensive community-based outreach services.
