Research shows that smartphone-delivered cognitive behavior therapy (CBT) with coaching may be a scalable and effective treatment for BDD. However, evidence for long-term gain maintenance is limited. Objectives: The aim of the current study was to examine the long-term outcomes of a smartphone-based CBT for BDD. Method: Adults with a primary diagnosis of BDD who completed a 12-week course of smartphone-delivered CBT with coach support were evaluated 3- and 12-months posttreatment. Symptom severity, remission and responder status were assessed with the clinician-rated Yale-Brown Obsessive-Compulsive Scale modified for BDD (BDD-YBOCS). Secondary outcomes were also evaluated and included BDD-related insight, depression, functioning and quality of life. Data were analyzed using four different approaches to missing data, with maximum likelihood estimation as the main approach. Results: = 33) follow-up. The mean BDD-YBOCS severity score remained stable during the follow-up period [Estimated Mean (SE) at posttreatment, 3-months, and 12-months = 18.7(1.1), 18.9(1.2) and 18.8(1.3), respectively]. The proportion of participants responding to treatment and in remission remained relatively unchanged as well (63 % responders and 46 % remitters at posttreatment, 54 % and 35 % at 3-month follow-up, and 61 % and 37 % at 12-month follow-up, respectively). Posttreatment gains in BDD-related insight, functioning, and quality of life were maintained; there were small increases in depression (ES = 0.36) from posttreatment to 12-month follow-up. Conclusions: Improvements after coach-supported smartphone-based CBT for BDD are maintained one year after treatment.","journal":"Internet Interventions","year":2025,"id":525183,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9523,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":378034,"name":"Susanne S.
