Short-term Effects of a School-based Health Promotion Program on Coping and Self-efficacy in Sixth Graders. A Pilot Study This study aimed to provide initial evidence on the short-term effectiveness of a school-based universal health promotion program for adolescents, focusing on coping and self-efficacy. Forty sixth graders (M = 11,83, SD = 0,59 years; 43 % female) participated in the study to determine if these personal protective factors changed in the intervention group (IG) compared to an untreated control group. A supplementary qualitative interview (n = 2) offered deeper insights into the changes within the IG. The results indicated improvements in emotion regulation, positive self-instructions, and social support seeking during stressful social situations. However, for the first time, a negative effect occurred, i.e., in rumination. Self-efficacy also improved in the short term. The interviews supported successful application of emotion regulation strategies, effective time management techniques, and increased self-efficacy. It is recommended to expand the program by including problem-solving strategies, gender-specific elements, and a more intensive focus on reflecting on maladaptive coping. Overall, the preliminary findings suggest that the new school-based program is a promising universal prevention approach that may improve the key personal protective factors of "coping" and "selfefficacy" among sixth graders. This may contribute to strengthening essential protective factors for adolescent mental health during a critical developmental stage.
