Brief Summary:
The purpose of this study is to investigate the effectiveness of using incentives to encourage adults to be physically active.

Condition or disease Intervention/treatment Phase
Health Behavior Physical Activity Behavioral: Non-cash incentives Behavioral: Self-monitoring physical activity levels Phase 2 Phase 3

Detailed Description:
The investigators developed the Physical Activity Loyalty Card (PAL) Scheme which integrates a novel physical activity tracking system with web-based monitoring and nudge initiatives. The tracking system used Near-Field Communication (NFC) technology and a "loyalty card" (PAL Card) which contained a passive Radio Frequency Identification (RFID) tag. Sensors were placed along footpaths in the outdoor environment, in the gym and exercise studio, and participants scanned their PAL card at the sensor when doing physical activity (e.g. walking). A transaction (card ID, sensor ID, and timestamp) was recorded and sent via SMS to a secure data centre. Participants logged onto a personal account on the study website (www.palcard.co.uk) and received real-time feedback on various aspects of their physical activity including minutes, distance and calories expended.

Arm Intervention/treatment
Experimental: Incentive
Participants use their PAL card to self-monitor physical activity levels (intrinsic motivation) and minutes of physical activity were converted to points (1 minute of physical activity = 1 point; capped at 30 points per day) over the 12-week intervention period. Points are redeemed for rewards (extrinsic motivation) at week 6 and week 12.
Behavioral: Non-cash incentives
Participants used their PAL card to self-monitor physical activity levels (intrinsic motivation) and minutes of physical activity were converted to points (1 minute of PA = 1 point; capped at 30 points per day) over the 12-week intervention period. Points were redeemed for rewards (extrinsic motivation) at week 6 and week 12.

Active Comparator: No Incentive
Participants used their PAL card to self-monitor their physical activity levels (intrinsic motivation) over the 12-week intervention period but do not collect points or earn rewards.
Behavioral: Self-monitoring physical activity levels
For those in the 'No Incentive' arm, participants used their PAL card to self-monitor their physical activity levels but did not collect points or earn rewards.




Primary Outcome Measures :

    Quality of life

  3. Physical Activity Self-Efficacy Scale [ Time Frame: baseline, week 12 and 6 months ]
    Physical activity self-efficacy

  4. Work absenteeism [ Time Frame: baseline, week 12 and 6 months ]
    Number of sick days from work

  5. Exit questionnaire [ Time Frame: week 12 ]
