Brief Summary

This study aims to test whether incentives can motivate children to promote increased physical activity of a working parent while also increasing their own activity levels.

Physical Activity

Physical activity; Financial incentives; Children; Parents; RCT; Wireless pedometer

Outcome Measures

Primary Outcomes (1)

• Changes in step count of parents from baseline to month 6, and month 12.

  Step counts of parents will be measured via the ActiGraph GT-3X+ accelerometer worn for a one-week period (with a minimum of 3 weekday days and 1 weekend day of at least 10 hours of wear time each day) at baseline, month 6, and month 12.

  Baseline, 6 months and 12 months

Secondary Outcomes (24)

• Changes in step count of children from baseline to month 6, and month 12.

  Baseline, 6 months and 12 months

• Changes in moderate to vigorous physical activity (MVPA) bout minutes of parents from baseline to month 6, and month 12.

  Baseline, 6 months and 12 months

• Changes in moderate to vigorous physical activity (MVPA) bout minutes of children from baseline to month 6, and month 12.

  Baseline, 6 months and 12 months

• Changes in moderate to vigorous physical activity (MVPA) minutes of parents from baseline to month 6, and month 12.

Study Arms (2)

Child-based Incentive (CBI)

ACTIVE COMPARATOR

Children earn rewards each week (with the week beginning on Monday and ending on Sunday) that they log 10,000 daily steps on the Fitbit according to the schedule below and their matched parent logs at least 2,000 steps on ≥4 of 7 days each week (regardless of which 4 of the 7 days they wear it). Incentives are tied, in addition to child's activity, to parent's Fitbit wear so that the investigators are better able to capture parent's activity in this arm. Step Targets for Children in CBI arm: * Months 1 - 3: ≥10,000 daily steps on ≥4 out of 7 days each week * Months 4 - 6: ≥10,000 daily steps on ≥5 out of 7 days each week * Months 7 - 12: ≥10,000 daily steps on ≥6 out of 7 days each week

Device: Fitbit; Behavioral: Incentives

Family-based Incentive (FBI)

EXPERIMENTAL

Children earn rewards each week that they log daily steps on the Fitbit according to the schedule below but only if their matched parent also logs 10,000 steps according to the schedule below. Otherwise, children earn no incentive for that week. Step targets for children and parents in FBI arm: * Months 1 - 3: ≥10,000 daily steps on ≥4 out of 7 days each week * Months 4 - 6: ≥10,000 daily steps on ≥5 out of 7 days each week * Months 7 - 12: ≥10,000 daily steps on ≥6 out of 7 days each week

Device: Fitbit; Behavioral: Incentives

Interventions

Fitbit DEVICE

Fitbit devices are wireless pedometers that track the steps of participants, and will be offered in conjunction with a tailored website with customized information for participants.

Also known as: Fitbit Zip, Fitbit Flex, wireless pedometer, physical activity tracker

Child-based Incentive (CBI); Family-based Incentive (FBI)

Incentives BEHAVIORAL

Incentives will be awarded to participating children for meeting step targets as measured by the Fitbit pedometer.

Also known as: Rewards, gift vouchers

Child-based Incentive (CBI); Family-based Incentive (FBI)
