NCT07683858
School Program for Resilience and Bullying Prevention
This study evaluated whether a school-based psychoeducational program could improve psychological resilience and reduce bullying victimization among high school students in Hatay, Türkiye, following the 2023 earthquake. The intervention consisted of a 10-week psychological resilience program followed by a 5-week peer bullying awareness program delivered in weekly group sessions. A single-group pretest-posttest mixed-methods design was used. Psychological resilience and bullying victimization were assessed before the intervention and three months after program completion using validated self-report scales. Qualitative data were also collected to explore students' experiences and perceived benefits of the program.

Evaluation of the Effect of a PRECEDE-PROCEED Model-Based "Laughter Yoga-Supported Education Program" on Peer Bullying
Adolescence is a critical developmental period marked by rapid cognitive, emotional, and social changes that shape personality and psychosocial functioning. During this stage, peer relationships play a central role in adolescents' mental well-being, academic performance, and social adjustment. However, unhealthy peer interactions and exposure to peer bullying significantly increase the risk of adverse physical, psychological, and social outcomes, including anxiety, depression, low self-esteem, academic difficulties, and risky health behaviors, making bullying a major public health concern. Recent evidence indicates a rising prevalence of peer bullying, particularly among middle school students, highlighting the need for effective school-based interventions. Previous programs have demonstrated reductions in bullying behaviors and improvements in school adjustment and self-confidence, yet meta-analytic findings suggest that existing educational interventions have limited effectiveness, underscoring the need for innovative and theory-driven approaches. The PRECEDE-PROCEED Model offers a comprehensive framework for designing sustainable health promotion interventions by addressing predisposing, enabling, and reinforcing factors influencing behavior. In this context, a laughter yoga-supported education program grounded in this model aims to increase adolescents' awareness of peer bullying, enhance physiological, psychological, and social well-being, strengthen social interaction, and improve quality of life. To date, no studies have examined the effects of a PRECEDE-PROCEED Model-based laughter yoga intervention on peer bullying. The aim of this study is to examine the effect of the "Laughter Yoga-Supported Education Program," developed based on the PRECEDE-PROCEED Model, on peer bullying among adolescents. Objectives: To improve adolescents' levels of awareness regarding peer bullying through the PRECEDE-PROCEED Model-based "Laughter Yoga-Supported Education Program," To enhance adolescents' awareness of health behaviors related to peer bullying through the PRECEDE-PROCEED Model-based "Laughter Yoga-Supported Education Program," To develop adolescents' social skills through PRECEDE-PROCEED Model-based laughter yoga educational practices, To significantly reduce the post-test mean peer bullying scores of adolescents in the intervention group compared with their pre-test mean scores, To ensure that the findings of the study contribute to the literature and guide future research on PRECEDE-PROCEED Model-based interventions. Hypotheses: H0-1: There is no significant difference in Peer Bullying Identification Scale scores between adolescents who receive the PRECEDE-PROCEED Model-based Laughter Yoga-Supported Education Program and those who do not. H1-1: There is a significant difference in Peer Bullying Identification Scale scores between adolescents who receive the PRECEDE-PROCEED Model-based Laughter Yoga-Supported Education Program and those who do not.
