Baecke habitual physical activity questionnaire and body mass index (BMI) were used as research tools. Mixed analysis of variance method was used for analyzing. . Results indicated the significant effect of within subject factors in BMI and activity in leisure time, but in between subject factors groups has significant difference only in activity in leisure time, so that CBT and MBCT groups got higher scores in this variable.
