Protocol summary

Study aim
Determining the effectiveness of dialectical behavior therapy on emotion regulation, impulsivity, depression, anxiety, executive function, body mass index, and waist circumference in overweight and obese adolescent girls
Design
This is a randomized controlled trial with two groups of dialectical behavior therapy and control group. 40 obese and overweight adolescents who meet the inclusion criteria will be selected by purposive sampling. Participants in the intervention and control groups are randomly assigned and both groups are grouped according to all known factors. Then the subjects will be replaced in the 20-person dialectical behavior therapy and control groups.
Settings and conduct
The researcher will refer to the Education Department of Kashan with a letter from Kashan University of Medical Sciences. Then some schools will be selected using random sampling. Then, by going to schools, students who are overweight and obese as well as other criteria will be selected through purposeful sampling. Then one of the schools in Kashan will be selected as the research site.  Subjects will then be replaced in the 20-person DBT and control groups. This study is a single blind study and the members of each group will be unaware of the intervention type of the other group

General information

Reason for update
Reason for general update: End of clinical trial Specific causes: change in the maximum age of the sample due to the difference in stress levels of students in the first and second high schools, change in the criterion of body mass index due to differences in how the body mass index is calculated in adolescents compared to adults, change in expected onset and end of disease owing to the delay in receiving the code of ethics.
