Study Arms (3)

NEAT!2

EXPERIMENTAL

Participants will be asked to use the NEAT!2 app for 3 months after randomization. App use between 4-6 months is optional.

Behavioral: NEAT!2

NEAT!2+Calls

EXPERIMENTAL

Participants will be asked to use the NEAT!2 app for 3 months after randomization. In addition, participants will receive bi-weekly coaching calls over 3 months. App use between 4-6 months is optional.

Behavioral: NEAT!2+Calls

Delayed NEAT!2

OTHER

Participants will receive the NEAT!2 app to use between 3 and 6 months.

Behavioral: Delayed NEAT!2

Interventions

NEAT!2BEHAVIORAL

Participants randomized to NEAT!2 will have their NEAT!2 app turned on after randomization. When 30 minutes of continuous non-movement or sedentary time is detected, the NEAT!2 app will provide a vibration or audio notification as well as display a reminder on the phone's lock/home screen. Participants will be asked to use the app for the 3 months of the intervention. Participants will be given an initial goal to reduce total sedentary time by 30 minutes/day, ultimately progressing to a 90 minute/day reduction by 3 months. After the 3-month assessment, participants randomized to NEAT!2 will have the option to continue using the app until 6 months.

NEAT!2
NEAT!2+CallsBEHAVIORAL

Participants in this group will have their NEAT!2 app turned on after randomization. In addition, to receiving the identical app and given the same goals as participants randomized to NEAT!2, NEAT!2+Calls participants will receive 10-15 minute bi-weekly coaching calls. After the 3-month assessment, participants will have the option to continue using the app until 6 months. During this time, participants will not receive any coaching calls.

NEAT!2+Calls
Delayed NEAT!2BEHAVIORAL

Participants randomized to Delayed NEAT!2 will not receive any contact or app between baseline and 3 months. However, after completing the 3-month assessment, participants will receive the NEAT!2 application. Participants will then have the option to use the app between 3 and 6 months.

Delayed NEAT!2
