  abstract  = {BackgroundAlthough the efficacy of Internet- and mobile-based interventions (IMIs) for anxiety is established, little is known about the intervention components responsible for therapeutic change. We conducted the first comprehensive meta-analytic review of intervention components of IMIs for adult anxiety disorders. MethodsRandomized controlled trials (RCTs) comparing IMIs for anxiety disorders to active online control groups, or IMIs to dismantled variations of the same intervention ( specific components) were identified by a systematic literature search in six databases. Outcomes were validated observer-rated or self-report measures for anxiety symptom severity and treatment adherence (number of completed modules and completer rate). This meta-analytic review is registered with PROSPERO (CRD42017068268). ResultsWe extracted the data of 34 RCTs (with 3,724 participants) and rated the risk of bias independently by two reviewers. Random-effects meta-analyses were performed on 19 comparisons of intervention components (i.a., different psychotherapeutic orientations, disorder-specific vs. transdiagnostic approaches, guidance factors). IMIs had a large effect when compared to active online controls on symptom severity (standardized mean difference [SMD] of -1.67 [95\% CI: -2.93, -0.42]; P=0.009). Thereby, guided IMIs were superior to unguided interventions on symptom severity (SMD of -0.39 [95\% CI: -0.59, -0.18]; P=0.0002) and adherence (SMD of 0.38 [95\% CI: 0.10, 0.66]; P=0.007). ConclusionsOverall, the results of this meta-analysis lend further support to the efficacy of IMIs for anxiety, pointing to their potential to augment service supplies. Still, future research is needed to determine which ingredients are essential, as this meta-analytic review found no evidence for incremental effects of several single intervention components apart from guidance.},

  abstract  = {Background: Web-based interventions have been introduced as novel and effective treatments for mental disorders and, in recent years, specifically for the bereaved. However, a systematic summary of the effectiveness of online interventions for people experiencing bereavement is still missing. Objective: A systematic literature search was conducted by four reviewers who reviewed and meta-analytically summarized the evidence for web-based interventions for bereaved people. Methods: Systematic searches (PubMed, Web of Science, PsycInfo, PsycArticles, Medline, and CINAHL) resulted in seven randomized controlled trials (N= 1,257) that addressed adults having experienced bereavement using internet-based interventions. We used random effects models to summarize treatment effects for between-group comparisons (treatmentvs.control at post) and stability over time (postvs.follow-up). Results: All web-based interventions were based on cognitive behavioral therapy (CBT). In comparison with control groups, the interventions showed moderate (g= .54) to large effects (g= .86) for symptoms of grief and posttraumatic stress disorder (PTSD), respectively. The effect for depression was small (g= .44). All effects were stable over time. A higher number of treatment sessions achieved higher effects for grief symptoms and more individual feedback increased effects for depression. Other moderators (i.e.dropout rate, time since loss, exposure) did not significantly reduce moderate degrees of heterogeneity between the studies. Limitations: The number of includable studies was low in this review resulting to lower power for moderator analyses in particular. Conclusions: Overall, the results of web-based bereavement interventions are promising, and its low-threshold approach might reduce barriers to bereavement care. Nonetheless, future research should further examine potential moderators and specific treatment components (e.g.exposure, feedback) and compare interventions with active controls.},
