Motivation and perceived competence for healthy eating and exercise among overweight/obese adolescents in comparison to normal weight adolescents

Table 2 Motivation, perceived competence, and self-efficacy

	Normal weight	Overweight + Obese
	Mean ± SD	Mean ± SD
Motivation for Eating a Healthy Diet
Autonomous (n = 99)	34.1 ± 6.5	36.5 ± 4.6
Controlled (n = 96)	18.1 ± 8.1	23.8 ± 9.3**
Motivation for Exercise
Autonomous (n = 99)	33.1 ± 7.9	35.9 ± 6.9
Controlled (n = 96)	18.8 ± 8.8	22.6 ± 10.4
Perceived Competence - Diet (n = 100) median (25-75% IQR)	20.0 (14.5-24.0)	22.5 (19.0-26.0)*
Perceived Competence - Exercise (n = 100) median (25-75% IQR)	23.5 (15.5-25.0)	24.0 (20.5-28.0)
Self-Efficacy (n = 77)	31.5 ± 5.4	31.6 ± 4.5

Legend: Subjects completed the Treatment Self Regulation Questionnaire (TSRQ) for eating a healthy diet and exercise, the Perceived Competence Scales for Eating Healthy and Exercising Regularly, and the General Self-Efficacy Scale. Subjects assigned a score between 1 and 7 for each item, with higher scores indicating the statement is more “true” for themselves. The data are expressed as the means ± standard deviation (SD), or as the median with the 25-75% interquartile range (IQR) for non-normal data (perceived competence)
*p < 0.05, **p < 0.01 for comparisons between normal weight subjects and overweight/obese subjects
