SECONDARY outcome
Timeframe: Measured at baseline, week 12 and 24Population: The participants in the N1L1P0R0 group were not assessed because they walked too many steps at the baseline period
Measured using the Exercise Self-Efficacy Scale at baseline, week 12 and week 24 (McAuley E 1993). This scale measures self-efficacy on nine different measures from not confident (0 rating) to very confident (10 rating).The range is 0 to 10. A higher rating indicates that the respondent is more confident they will be able to overcome barriers to physical activity.

SECONDARY outcome
Timeframe: Measured at baseline, week 12 and 24Population: The participants in the N1L1P0R0 group were not assessed because they walked too many steps at the baseline period
Measured using the Motivation for Physical Activity Measurement (MPAM) at baseline, week 12 and week 24 (Frederick CM 1993). This scale measures reasons and motivations for participating in physical activity having respondents indicate why they exercise. The scale ranges from 1=very true for me, 2= somewhat true for me, 3=neither true nor untrue for me, 4=somewhat untrue for me, 5= very untrue for me. The minimum score is 1 and the maximum is 5. Higher scores means more intrinsic motivation to exercise.
