Background: One of the most health problems in adolescent is obesity. Obesity is correlated with impairments on risky decision making and food addiction. Standard bio-psycho-socials treatments have many limitations that cause to relapses in diet by obese participants. Base on this factors, this study investigate Acceptance and commitment treatment (as emerging and promising field) for risky decision making, food addiction severity index, and BMI in adolescent girls with overweight and obesity.
Material and Methods: 60 obese girls were selected to attend in this study using convenient sampling method. The participants were randomly classified into two groups of control and experimental groups. In experimental group acceptance and commitment therapy was applied and in control group psycho-education. Every participant receive specific diet therapy. For collecting data the PC version of IOWA gambling task, Yale food addiction scale, and BMI index were utilized. The mean and standard deviation of descriptive statistics were used for illustrating and depicting the data. Also, in order to analyze the data, ANOVA with repeated measure and chi-squared tests were employed.
Results: The mean score of risky decision making in experiment group was significantly higher than control group (P<0.05) during post-test and follow up. In addition, food addiction rate was significantly lower in experiment group than control group through post-test and follow up. The results of repeated measures ANOVA for comparison of the changes of BMI showed that in posttest and follow up, the mean score of this variable in the experimental group was significantly higher than the control group (p˂0.001)
Conclusion: Acceptance and commitment therapy can significantly lead to improvement of risky decision making system and food addiction in with overweight and obesity. Also this treatment can decline BMI index in obese and overweight girls.
