Abstract: This study aimed to review and compare the effects of Face-to-Face Cognitive Behavioral Therapy (F2FCBT) and Behavioral Intervention Technologies (BITs) for youth anxiety disorders. Anxiety disorders in youth are linked to impaired social and academic functioning; however, only 20% of individuals with these disorders receive treatment. The current stigma of seeing a psychologist or the accessibility of resources may represent barriers to treatment. BITs are electronic interventions (e.g. mobile phones, internet, virtual reality) that aim to help the user improve mental and physical health. F2F and BITs treatments have many areas of overlap that draw on traditional research methods in randomized controlled trials. However, comparing F2F and Internet-based treatments is not an “apples to apples” approach. The purpose of this presentation is to provide information about assessing methodological quality, measurement, and treatment in online and face-to-face environments.


Methods: Systematic review methods and meta-analysis techniques were used to analyze thirty-four randomized controlled trials that included F2FCBT and/or BITs therapy. The process of selecting outcome variables for anxiety review is discussed, based on variability of anxiety measures in the groups. Furthermore, recommendations for consideration of methodological quality (Deeks, 2003) given online and in-person compairsons will be reviewed, including design, group comparability, treatment, measurement, attrition, and analysis. .  


Results: Results of the sample analysis will be reviewed, as both types of interventions were effective for the reduction of childhood anxiety, with the overall effect for F2FCBT indicating less post-test anxiety (F2FCBT g = -.84 and BITs g = -.40). Furthermore, subgroup analyses based on separate and mixed treatments  analysis revealed that there were significant effect sizes for F2FCBT and for the combination of the two modalities, but not for BITs alone.


Conclusion: Although F2FCBT has shown a larger effect size, BITs with guided therapist help can be an effective modality for delivering treatment for youth with anxiety disorders.
