Key takeaways

  • 18 studies (n = 1707) only RCTs
  • Compared to passive control groups (waitlist): g = -0.59 (95% CI -0.99 to -0.18), p = 0.01 on the Y-BOCS at post. No significant difference when compared to active control
  • Moderator: contact with a therapist, diagnosis based on DSM criteria, mean age, gender, type of tech, duration of intervention, study quality
  • Interventions
    • Association Splitting sent through email (k = 2)
    • Metacognitive Training self-help book via email (k = 6)
    • ICBT (k = 7)
    • Competitive memory training delivered via a download (k = 1)
    • Web-based CBT program with voicemail system and workbook via telephone (k = 1)

No strong moderating effect among the ones listed above. There was a somewhat stronger effect when only including studies with low risk of bias, g = 0.88 (95% CI -1.56 to -0.21), p = 0.02.
