How Computerized CBT May Aid Depression, Anxiety
HealthDay News — For patients with depression and anxiety, online computerized cognitive behavioral therapy (CCBT) provided via a collaborative care program is beneficial, but combining an internet support group (ISG) with CCBT offers no additional benefit, according to a study published online November 8 in JAMA Psychiatry.
Bruce L. Rollman, MD, MPH, from the University of Pittsburgh School of Medicine in Pittsburgh, and colleagues conducted a 3-arm randomized trial in which primary care physicians from 26 practices referred 2,884 patients (aged 18 to 75 years) in response to an electronic medical record prompt. Seven-hundred four patients were eligible and randomized to CCBT alone (301 patients), CCBT+ISG (302 patients), or usual care (101 patients). A total of 604 patients completed the primary outcome assessment at six months.
The researchers found that similar 6-month improvements were reported in mental health-related quality of life, mood, and anxiety symptoms for patients receiving CCBT+ISG compared with patients receiving CCBT alone. Patients in the CCBT-alone cohort reported significant six-month effect size improvements in mood and anxiety compared with patients receiving usual care (effect size, 0.31 and 0.26, respectively); these improvements persisted six months later. Completing more CCBT sessions was correlated with greater effect size improvements in mental health-related quality of life and symptoms.
"While providing moderated access to an ISG provided no additional benefit over guided CCBT at improving mental health-related quality of life, mood, and anxiety symptoms, guided CCBT alone is more effective than usual care for these conditions," the authors write.
