The effect of health psycoeducation program on nutrition, physical activity and health locus of control of obese adolecent

In this study, the aim was to evaluate the effect of the health psychoeducation program applied to obese adolescents on the nutrition and physical activity habits of obese adolescents and health locus of control. This research, which was carried out in a weak experimental model design, was carried out on the basis of the experimental and control groups and the pretest-posttest and follow-up test scheme. Participants were reached by snowball sampling method. A total of 24 obese adolescents between the ages of 12-17 participated in the study, 12 of which were in the experimental group and 12 in the control group. In the collection given; The Nutrition Change Processes Scale, the Exercise Change Processes Scale, the Multidimensional Health Control Locus Scale and the Introductory Information Form for the Individual were used. In the analysis of data; The Unrelated Sample T Test was used to compare the experimental and control groups, and the Related Sample T Test was used to compare the pretest-posttest and follow-up tests. Looking at the results of the research; According to the arithmetic averages of the pre-test total scores of the experimental and control groups; When the internal and external focus scores of the BDSÖ, EDSÖ and ÇBSDOÖ sub-dimensions were compared, it was found that there was a statistically significant difference between the two groups. According to the arithmetic averages of the pretest and posttest total scores of the experimental group; Statistically significant difference was found when all sub-dimensions of BDSÖ, EDSÖ and ÇBSDOÖ were compared. According to the arithmetic averages of the posttest total scores of the experimental and control groups; A statistically significant difference was found between the two groups when all sub-dimensions of BDSÖ, EDSÖ and ÇBSDOÖ were compared. According to the arithmetic averages of the posttest and follow-up test total scores of the experimental group; When all sub-dimensions of BDSÖ, EDSÖ and ÇBSDOÖ were compared, no statistically significant difference was found.
