Self-efficacy is an individuals' confidence in their ability to successfully perform a particular task. Self-efficacy beliefs therefore play a role in maintenance of health behaviours over time. This survey asks key questions such as - I think I can be physically active no matter how busy my day is; I think I can be physically active after school even if my friends want me to do something else; I think I can ask my parent/guardian to get me the equipment I need to be physically active; I think I can be physically active after school even if I could watch TV or play video games instead
