Long-term effects of a universal prevention program for depression in children: a 3-year follow-up study

Evaluating the effectiveness of a transdiagnostic universal prevention program for both internalizing and externalizing problems in children: two feasibility studies

BACKGROUND

The present study examined the effectiveness of the Universal Unified Prevention Program for Diverse Disorders (Up2-D2) for internalizing and externalizing problems for children aged 9-11 years.

METHODS

We used two feasibility studies. The Up2-D2 entailed 12 sessions delivered by teachers; each session was developed based on cognitive-behavioral and positive psychological interventions. In Studies 1 and 2, 58 elementary school children aged 9-11 and 73 elementary school children aged 10-11 attended the Up2-D2. The teachers in Study 1 received 1.5 h of on-site teacher training for learning rationales for interventions, how to run the program, and received ongoing supervision by professionals with mental health expertise. In contrast, the teachers in Study 2 were given self-learning DVD materials in place of on-site training and ongoing supervision.

RESULTS

Mixed models revealed that general difficulties, which is total score of both internalizing and externalizing problems, decreased in Study 1 but not in Study 2. Additional analyses for children with subclinical general difficulties revealed that general difficulties, internalizing problems, and externalizing problems decreased in Study 1, whereas in Study 2, general difficulties and internalizing problems decreased, except for externalizing problems.

CONCLUSIONS

These results suggest that on-site teacher training and ongoing supervision are imperative for improving general difficulties in children at a universal level. In addition, universal preventive interventions by classroom teachers without on-site training and continuous supervision might be efficacious for reducing general difficulties and internalizing problems for children with subclinical difficulties.

Developing the universal unified prevention program for diverse disorders for school-aged children

BACKGROUND

Psychological problems during childhood and adolescence are highly prevalent, frequently comorbid, and incur severe social burden. A school-based universal prevention approach is one avenue to address these issues.

OBJECTIVE

The first aim of this study was the development of a novel, transdiagnostic cognitive-behavioral universal prevention program: The Universal Unified Prevention Program for Diverse Disorders (Up2-D2). The second aim of this study was to examine the acceptability and fidelity of the Up2-D2.

METHODS

Classroom teachers who attended a 1-day workshop implemented the Up2-D2 independently as a part of their regular curricula. To assess the acceptability of the Up2-D2, 213 children (111 boys and 102 girls) aged 9-12 years completed questionnaires about their enjoyment, comprehension, attainment, applicability, and self-efficacy after completing Lessons 1-12. For fidelity, research assistants independently evaluated audio files that were randomly selected and assigned (27.3%).

RESULTS

Our preliminary evaluation revealed the program was highly enjoyable, clear, and applicable for students. In addition, self-efficacy demonstrated a trend of gradually increasing over the 12 sessions. The total fidelity observed in the two schools was sufficient (76.2%), given the length of the teacher training.

CONCLUSIONS

The results of this study supported the theory that the Up2-D2 could be feasible in real-world school settings when classroom teachers implement the program. We discussed current research and practical issues of using universal prevention to address mental health problems in school, based on implementation science for user-centered design.
