Objective: This study aimed to examine the effect of training based on the Health Promotion Model (HPM) on adolescents' healthy lifestyles and self-efficacy. Method: Adolescents were assigned to the intervention group (42 from the first school) and the control group (42 from the second school) using stratified sampling and a random number table in a computer environment. Seven adolescents (3 from the intervention group, 4 from the control group) who missed any of the training sessions, and 5 adolescents (3 from the intervention group, 2 from the control group) who filled out the questionnaires incorrectly or incompletely, were omitted from the study. This randomized controlled experimental study was conducted in Kahramanmaraş province, Türkiye. The study included 72 adolescents aged 14-15 (36 in the intervention group and 36 in the control group) who were enrolled in 2 high schools affiliated with the Directorate of National Education. Data were collected through the Adolescent and Parent Information Survey, the Adolescent Lifestyle Profile (ALP), and the Self-Efficacy Scale (SES). Ethics approval, institutional permission, and written and verbal consent from adolescents and their parents were obtained. The intervention group received a 6-session healthy lifestyle education, using video animation and the Phillips 66 group discussion technique. In the study, the pre-test was conducted on March 15, 2022, the posttest on April 26, 2022, and the first posttest on May 24, 2022. Data were analyzed using descriptive statistics, homogeneity tests, Fisher's exact test, and analysis of variance (2-way ANOVA), with a significance level set at P < .05. Results: The adolescents in the intervention group were subjected to the healthy lifestyle training consisting of 6 sessions through video animation and the Phillips 66 group discussion technique. No significant difference was found between the pretest mean scores of the ALP and SES in the intervention and control groups. The first posttest mean scores of the ALP and SES in the intervention group were higher than those in the control group, and the difference between them was significant. The difference between the pre-test (96.52 +/- 13.15) and posttest (127.00 +/- 17.15) scores of the ALP, as well as the pre-test (78.19 +/- 12.06) and posttest (93.30 +/- 9.72) scores of the SES in the intervention group is statistically significant. A significant difference was found between the posttest mean scores of the intervention and control groups (P < .001). Conclusion: The training, based on a HPM and delivered using video animation and the Phillips 66 technique, has had a positive impact on adolescents' healthy lifestyle behaviors and self-efficacy.
