A meta-analysis of randomized controlled trials","abstract":"BACKGROUND: Various psychological interventions are effective for reducing symptoms of anxiety when used alone, or as an adjunct to anti-anxiety medications. Recent studies have further indicated that smartphone-supported psychological interventions may also reduce anxiety, although the role of mobile devices in the treatment and management of anxiety disorders has yet to be established. METHODS: We conducted a systematic review and meta-analysis of all randomized clinical trials (RCTs) reporting the effects of psychological interventions delivered via smartphone on symptoms of anxiety (sub-clinical or diagnosed anxiety disorders). A systematic search of major electronic databases conducted in November 2016 identified 9 eligible RCTs, with 1837 participants. Random-effects meta-analyses were used to calculate the standardized mean difference (as Hedges' g) between smartphone interventions and control conditions. RESULTS: Significantly greater reductions in total anxiety scores were observed from smartphone interventions than control conditions (g=0.325, 95% C.I.=0.17-0.48, p<0.01), with no evidence of publication bias. Effect sizes from smartphone interventions were significantly greater when compared to waitlist/inactive controls (g=0.45, 95% C.I.=0.30-0.61, p<0.01) than active control conditions (g=0.19, 95% C.I.=0.07-0.31, p=0.003). LIMITATIONS: The extent to which smartphone interventions can match (or exceed) the efficacy of recognised treatments for anxiety has yet to established. CONCLUSIONS: This meta-analysis shows that psychological interventions delivered via smartphone devices can reduce anxiety. Future research should aim to develop pragmatic methods for implementing smartphone-based support for people with anxiety, while also comparing the efficacy of these interventions to standard face-to-face psychological care.","is_dataset_classified":null,"base_score":6.651571873589727,"endowment":6.651571873589727,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"28456072","pmcid":null,"openalex_id":"https://openalex.org/W2609940642","authors":[],"funders":[{"funder_name":"MRC","grant_id":"PP117413F07","title":null},{"funder_name":"Economic and Social Research Council","grant_id":"ESJ5000991","title":null},{"funder_name":"NHMRC","grant_id":"APP1125000","title":null},{"funder_name":"Economic and Social Research Council","grant_id":"1512010","title":null},{"funder_name":"Society for Mental Health Research Early Career Fellowship","grant_id":"","title":null}],"total_grants":5,"fwci":7.8604,"citation_percentile":0.99328859,"influential_citations":0,"citation_trend":[{"year":2017,"count":5},{"year":2018,"count":66},{"year":2019,"count":83},{"year":2020,"count":123},{"year":2021,"count":108},{"year":2022,"count":105},{"year":2023,"count":107},{"year":2024,"count":84},{"year":2025,"count":62},{"year":2026,"count":30}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"https://www.sciencedirect.com/science/article/pii/S0165032717300150/pdf","host_type":"journal"},{"url":"https://www.sciencedirect.com/science/article/pii/S0165032717300150/pdf","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0165032717300150?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0165032717300150?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.jad.2017.04.046","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/28456072","host_type":"repository"},{"url":"https://research.manchester.ac.uk/en/publications/1fbecb3e-df92-4293-b701-2923383680b8","host_type":"repository"},{"url":"https://www.research.manchester.ac.uk/portal/en/publications/can-smartphone-mental-health-interventions-reduce-symptoms-of-anxiety-a-metaanalysis-of-randomized-controlled-trials(1fbecb3e-df92-4293-b701-2923383680b8).html","host_type":"repository"},{"url":"http://hdl.handle.net/1959.3/436355","host_type":"repository"}],"fields_of_study":["Digital Mental Health Interventions","Mobile Health and mHealth Applications","Anxiety, Depression, Psychometrics, Treatment, Cognitive Processes","Anxiety","Anxiety Disorders","Humans","Mental Health","Psychotherapy","Randomized Controlled Trials as Topic","Smartphone"],"mesh_terms":["Smartphone","Anxiety","Anxiety Disorders","Humans","Mental Health","Psychotherapy","Randomized Controlled Trials as Topic"],"keywords":["Anxiety","Randomized controlled trial","Mental health","Meta-analysis","Psychological intervention","Psychology","Psychiatry","Clinical psychology","Medicine","Internal medicine","Panic Disorder","Anxiety Disorders","Obsessive-compulsive Disorder","E-health","Mhealth","Apps"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-05T22:11:05.737153Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
