The Effectiveness of Internet-Based Cognitive Behavioral Therapy (iCBT) for Depression and Anxiety: A Meta-Analysis of Randomized Controlled Trials
Abstract
Internet-Based Cognitive Behavioral Therapy (iCBT) has emerged as a convenient and accessible intervention for depression and anxiety, offering evidence-based treatment delivered through online platforms. This meta-analysis of randomized controlled trials (RCTs) evaluates the efficacy of iCBT in reducing symptoms of depression and anxiety and improving overall mental health outcomes. Through a comprehensive review of the literature, the meta-analysis synthesizes effect sizes from RCTs assessing the effectiveness of iCBT compared to control conditions (e.g., waitlist, face-to-face therapy) in targeting depressive and anxiety symptoms, functional impairment, and quality of life. Additionally, it examines potential moderators of treatment outcomes, such as program duration, therapist guidance, interactivity of the platform, and participant characteristics (e.g., age, severity of symptoms), to better understand the factors influencing the effectiveness of iCBT for depression and anxiety.
