Videoconferencing psychological therapy and anxiety: a systematic review.

Background: The growing worldwide prevalence of individuals with anxiety disorders has increased needs for mental health services. Due to limited number of mental health providers and community resources, especially in low-income countries, individuals often seek services from primary care settings. Through collaborative care models, services via telemedicine address the mental health provider shortage. While previous reviews show telemedicine effectively treats mental illness, a gap exists for reviews on videoconferencing psychological therapy for anxiety treatment. Objective: This systematic review aims to summarize videoconferencing psychological therapy for anxiety disorder treatment. Methods: Database searches were performed with PubMed, PsychINFO and Embase. Inclusion criteria identified controlled and uncontrolled studies evaluating videoconferencing psychological therapy. Studies were appraised using the Effective Public Health Practice Project Quality Assessment tool. Data collected included research design, sample size, intervention details, outcome results, intervention effect size and differences between videoconferencing psychological therapy and face-to-face therapy. Results: The search revealed 1253 articles, with 21 meeting inclusion criteria. Sample sizes ranged from 1 to 121 participants; cognitive-behavioral therapy was most commonly evaluated. Participants' diagnoses included panic disorder with and without agoraphobia, generalized anxiety disorder, social anxiety disorder, social phobia and hypochondriasis. Three studies occurred in outpatient health care settings. Fourteen studies reported statistically significant improvement on anxiety measures; 11 reported clinically significant improvements. Effect sizes ranged from small to very large, and all controlled studies found no differences between videoconferencing and face-to face groups. Conclusion: Results provide promise for evidence-based interventions delivered via videoconferencing psychological therapy. More rigorous research is needed in various settings and populations.

Videoconferencing Psychotherapy and Depression: A Systematic Review.

Introduction:Depression is the leading cause of disability in the world. Despite the prevalence of depression, a small proportion of individuals seek mental health services. A cost-effective method for increasing access to mental health services is the implementation of telemental-health programs. This review aims to summarize the state of the field on the efficacy and effectiveness of videoconferencing psychotherapy (VCP) for the treatment of depression.Materials and Methods:Systematic literature searches were performed using PsychINFO, PubMed, and EMBASE. Specific inclusion criteria were used to identify controlled and uncontrolled studies evaluating VCP for the treatment of depression. Data extraction included study assessment quality, research design, sample size, intervention details, outcome results, intervention effect size, and statistical differences between VCP and in-person (IP) therapy.Results:Of the 1,424 abstracts screened, 92 articles were critically reviewed. Thirty-three articles were included in the review, with 14 randomized controlled studies, 4 controlled nonrandomized studies, and 15 uncontrolled studies. Sample size ranged from 1 to 243 participants. Twenty-one studies reported statistically significant reductions in depressive symptoms following VCP, and the median effect size for studies ranged from medium to the very large range. Most controlled studies reported no statistical differences between VCP and IP groups receiving the same intervention.Conclusions:VCP for the treatment of depression is a promising method for delivering mental health services. More rigorous research is needed to evaluate VCP on depression in various contexts and participants.
