Abstract

Adolescent mental health is a pressing concern in urban Indonesian schools, where a significant gap exists between student needs and the availability of professional support. This study evaluated the efficacy of a culturally-adapted, school-based "Train-the-Trainer" (TtT) community service model designed to build sustainable mental health support capacity by empowering teachers. A quasi-experimental study with a matched control group was conducted in 20 public high schools in South Sumatera, Indonesia. Ten schools (n=150 teachers, n=1500 students) received the TtT intervention, where core teachers were trained to cascade mental health literacy and foundational support skills to their peers. Ten matched schools (n=145 teachers, n=1450 students) served as a control group. Data on teacher self-efficacy, student-reported support awareness, and school mental health policies were collected at baseline, 6-months, and 12-months. A linear mixed-effects model revealed a significant time-by-group interaction, with teachers in the intervention group reporting substantially higher confidence in supporting students at 12 months (M=4.15, 95% CI [4.01, 4.29]) compared to the control group (M=2.51, 95% CI [2.37, 2.65]), a large effect (d=2.41). Intervention students were significantly more likely to know how to access support (78% vs. 27%; OR=9.82, 95% CI [8.11, 11.89], p < 0.001). Intervention schools demonstrated a massive increase in formalized mental health protocols compared to control schools (IRR=7.94, p < 0.001). In conclusion, the TtT model is a highly effective and scalable strategy for building a foundational mental health support system within existing school structures in resource-constrained settings. By investing in local educators, this model fosters a sustainable, multi-tiered support ecosystem, offering a viable pathway for national policy and practice in Indonesia.

Abstract

Introduction: Early Childhood Caries (ECC) is a significant global health problem. Minimally invasive treatments like Silver Diamine Fluoride (SDF) and Glass Ionomer Cement (GIC) are crucial, but long-term comparative effectiveness data from real-world community settings are scarce. This study aimed to compare the three-year clinical performance of 38% SDF versus high-viscosity GIC in arresting active carious lesions in the primary molars of preschool children. Methods: This study was designed as a three-year, prospective, non-randomized, community-based cohort study in an underserved urban population in South Sumatra, Indonesia. A total of 450 children aged 3-5 years with at least one active cavitated carious lesion (ICDAS 5/6) in a primary molar were enrolled. Following parental consent and choice, lesions were treated with either a single application of 38% SDF or a high-viscosity GIC restoration using the Atraumatic Restorative Treatment (ART) technique. Calibrated examiners assessed the lesions for caries arrest at 6, 12, 24, and 36 months using standardized visual-tactile criteria. The primary outcome was the proportion of arrested lesions. Survival analysis was performed using Kaplan-Meier curves and a Cox proportional hazards model. Results: A total of 620 lesions (309 SDF, 311 GIC) were treated and followed. At the 36-month follow-up, the caries arrest rate in the SDF group was 81.2%, which was significantly higher than the 64.8% arrest rate observed in the GIC group (χ² = 24.5, p < 0.001). The Kaplan-Meier survival analysis demonstrated a significantly higher probability of lesions remaining in an arrested state in the SDF group over the three-year period (log-rank test, p < 0.001). The Cox regression model identified the treatment modality as the primary predictor of failure, with GIC having a hazard ratio of 2.15 (95% CI: 1.55-2.98) compared to SDF. Conclusion: Within the parameters of this community-based cohort study, a single application of 38% SDF was significantly more effective in arresting active carious lesions in primary molars over a three-year period than high-viscosity GIC applied via the ART technique. These findings support the prioritization of SDF in public health programs for managing ECC.

Abstract

Background. Digital interviews may offer scalable signals for identifying adolescents needing further assessment, but language models can appear accurate because of participant leakage, response length, or tuning-data evaluation. Objective. To develop and internally validate transcript-only probabilistic models of Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) screening positivity in the Multi-Modal Psychological Assessment (MMPsy) corpus and quantify incremental performance beyond response length. Methods. This secondary prediction-modeling study used 1,275 participants with Mandarin transcripts and complete PHQ-9 and GAD-7 scores. Transcripts were represented by term frequency-inverse document frequency character 2–4-grams and modeled with elastic-net logistic regression. Five-fold outer cross-validation estimated performance in unseen participants; four-fold inner cross-validation selected penalization, fitted Platt calibration, and set fold-specific thresholds targeting 0.80 sensitivity. Comparators were response length and training-fold prevalence. Intervals used 2,000 participant bootstraps. Results. Screening positivity occurred in 258 (20.2%) PHQ-9 and 136 (10.7%) GAD-7 participants. Transcript areas under the receiver operating characteristic curve were 0.791 (95% confidence interval 0.761–0.820) for PHQ-9 and 0.822 (0.784–0.857) for GAD-7; precision-recall areas were 0.453 and 0.356. Calibration intercepts were 0.02 and −0.02; slopes were 1.10 for both. At sensitivity-directed thresholds, sensitivity was 81.4% and 80.1%, positive predictive value 36.1% and 23.5%. Improvements over response length were small and uncertain. Decision-curve patterns favored transcript content more consistently for GAD-7 than PHQ-9. Conclusion. Participant-wise transcript models identified screening positivity with useful internal ranking and high negative predictive values, but incremental value and clinical utility were outcome-dependent. External, prospective, subgroup, and workflow validation are required before operational use.
