The second aim was to study differences in motivation according to adolescents educational level since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. Methods For the first study aim the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program BMI 35.9 6.0 kg m2 15.1 1.5 years 62 girls . A subsample of 65 adolescents stratified by educational level were divided into low n 34 versus high educated n 31 as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Results Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy r 0.31 p 0.001 introjected r .
