Obsessive compulsive disorder (OCD) is a psychiatric disorder with obsessive thoughts and compulsive behaviors. In Finland, the 1-year prevalence of OCD is 1.2% and lifetime prevalence is 1-3.3%. Standard treatment for OCD is drug therapy, cognitive behavioral therapy, or both combined. This systematic review investigates the efficacy of technology delivered therapeutic interventions for OCD. I conducted a comprehensive search using PubMed (23.12.2021). The search was limited to studies on adults with OCD (1992-2021). Inclusion criteria: (1) participant OCD diagnosis (DSM-IV/V or ICD-10); (2) main outcome measure of treatment efficacy quantified using Y-BOCS; (3) at least one psychosocial intervention studied; (4) not a systematic review or a meta-analysis; and (5) English publication. 7 studies were selected for review: three involved clinician-guided interventions and four self-guided interventions. The risk of bias of each study was assessed using the national guidelines taskforce criteria. Blinding and measuring of treatment adherence were the largest sources of bias. The outcome measures were Y-BOCS, depressive symptoms (e.g. BDI), functionality (e.g. GAF), and any other OCD measures assessed (e.g. OCI-R). Y-BOCS reduction was used to assess clinical significance. 3 Most interventions statistically significantly reduced OCD symptoms. Two studies produced a clinically significant Y-BOCS reduction. Depressive symptoms and functionality were improved by the test interventions. The review was limited by high risk of bias and inclusion of wait-list control setups.
