In brief

Study Aim and Methods (≈250 words) It aims to evaluate the effectiveness, user perceptions, and applicability of the e-CAMP intervention in improving mental well-being and reducing depressive symptoms among adolescents aged 11-15 years. The primary research question is whether e-CAMP can significantly reduce depressive symptoms, measured by the Patient Health Questionnaire-9 (PHQ-9). Secondary objectives are to examine whether e-CAMP : improves mental health literacy using the Chinese-version Universal Mental Health Literacy Scale for Adolescents (UMHL), promotes healthier smart device use as measured by the Smartphone Addiction Scale (SAS), increases physical activity assessed through the Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) , and to evaluate participants' perceptions of the intervention's applicability, acceptability through survey. A prospective two-arm cluster randomized controlled trial (RCT) following CONSORT 2010 guidelines will be conducted in eight eligible Hong Kong schools, which will be randomly assigned to either the intervention or usual-care group. A process evaluation will also be undertaken. 320 students will be recruited with inclusion criteria : Chinese students aged 11-15 years (Primary 5 to Secondary 2) with parental consent. Students with physical, cognitive, or mental conditions that may affect participation will be excluded. Students in the intervention group will receive usual school care and access to the e-CAMP mobile app, which they will be encouraged to use at least three times weekly for eight weeks (10-15 minutes per session). Students in the control group will receive usual school care, including a 45-minute nurse-led health talk and PowerPoint handouts.
