Materials and Methods
This cross-sectional study was conducted with participation of 250 overweight and obese adolescents selected through cluster sampling method fromMarch to April, 2016.

Results: The majority of participants (80%) were in inactive stages (pre-contemplation, contemplation, and preparation) of change for weight control, while only 20% of them were in active stages (action and maintenance). Also, results showed that a significant differencebetween stages and processes of change so that individuals' progress across stages of change frompre-contemplation to maintenance increased cognitive and behavioral processes’ scores (p < 0.05).
