However, structured interventions for adolescents in child and adolescent psychiatry (CAP), particularly in inpatient and day-treatment settings, remain scarce.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study evaluated the feasibility, acceptability, and perceived usefulness of a manualized DML group for adolescents in CAP and explored preliminary changes in digital self-efficacy and critical media literacy (CML).<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n A prospective single-arm feasibility study with an embedded pretest-posttest and session-level process evaluation was conducted across 3 CAP clinics in Germany. The intervention comprised 6 weekly 60-minute, manualized modules covering data protection, social media use, and digital violence. Sessions were delivered in an open-group format by trained clinical staff. Recruitment was embedded in routine care, and clinical group participation was independent of study evaluation. Adolescents and facilitators completed paper-and-pencil questionnaires at baseline (T1), after each session, and post intervention or discharge (T2). Analyses were primarily descriptive; exploratory pre-post analyses used paired\n t<\/jats:italic>\n tests.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The analytic feasibility sample comprised 121 adolescents who attended at least 1 module. T1 data were available for n=60 and T2 data for n=38. Overall, adolescents attended a median of 2 modules (IQR 1\u20103; mean 2.46, SD 1.65, range 1\u20106), and 45 attended at least 3 modules. Session-level ratings indicated moderate to high acceptability. Facilitator-rated manual fidelity was moderate to high. Retrospective T2 ratings indicated moderate to high helpfulness (n=38; mean 3.55, SD 1.18; median 4.0, IQR 3.0-4.0) and satisfaction (n=38; mean 3.79, SD 1.07; median 4.0, IQR 3.0-5.0), with no significant differences between completers and noncompleters for helpfulness (\n U<\/jats:italic>\n =125.00;\n P<\/jats:italic>\n =.60) or satisfaction (\n U<\/jats:italic>\n =122.00;\n P<\/jats:italic>\n =.53). Among completers (\u22653 modules and T2 data; n=28), didactic method acceptability was moderate (mean 2.85, SD 0.60), and perceived learning was moderate to high (mean 3.33, SD 0.95). Exploratory pre-post analyses indicated an increase in perceived self-efficacy for recognizing misinformation (n=21; T1 mean 2.94, SD 0.59; T2 mean 3.38, SD 0.63;\n t<\/jats:italic>\n 20<\/jats:sub>\n =2.58; Hedges\n g<\/jats:italic>\n =0.56, 95% CI 0.09\u20101.02;\n P<\/jats:italic>\n =.02). Overall CML increased descriptively (\n P<\/jats:italic>\n =.07), whereas digital media self-efficacy did not change significantly (\n P<\/jats:italic>\n =.27).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Our manualized DML group was feasible and acceptable in routine CAP. Open-group delivery and variable treatment stays limited intervention exposure and data completeness. Findings suggest that brief DML groups may address safety- and knowledge-oriented competencies, but controlled mixed methods studies with systematic recruitment and missing-data documentation are needed.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/90484","type":"journal-article","created":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T16:55:07Z","timestamp":1781196907000},"page":"e90484-e90484","source":"Crossref","is-referenced-by-count":0,"title":["Digital Media Literacy Group for Adolescents in Child and Adolescent Psychiatry: Prospective Multicenter Single-Arm Feasibility Study"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-4912-4722","authenticated-orcid":false,"given":"Ira-Katharina","family":"Petras","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7629-3451","authenticated-orcid":false,"given":"Sarah","family":"W\u00fcllner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-0175-969X","authenticated-orcid":false,"given":"Katharin","family":"Hermenau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1598-9603","authenticated-orcid":false,"given":"Kathleen","family":"Meerkamp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9269-596X","authenticated-orcid":false,"given":"Michael","family":"Siniatchkin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"key":"R1","unstructured":"Ito M Baumer S Bittanti M Cody R Herr-Stephenson B et al.
