Primary Outcome Measures:
  • physical activity [ Time Frame: 3 months ]
    physical activity will be assessed for 7 days at each data collection period; accelerometers will be used to assess physical activity amount and intensity


Secondary Outcome Measures:
  • Psychological need satisfaction in exercise [ Time Frame: 3 months ]
    This scale will be used to assess psychological needs related to exercise - autonomy, relatedness, and competence

  • Behavioral Regulation in Exercise [ Time Frame: 3 months ]
    This scale will be used to assess motivation for exercise

  • Satisfaction [ Time Frame: 3 months ]
    Satisfaction with the study will be assessed using standard questions


Enrollment: 160
Study Start Date: February 2012
Study Completion Date: December 2013
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: pedometers only
Participants randomized to this arm will receive pedometers only. They will participate in baseline and 3 months data collection.
Behavioral: TXT Me
text messages, physical activity, self determination theory, extrinsic motivation, intrinsic motivation, pedometers, walking, prompts
Experimental: pedometers + prompts
Participants randomized to this arm will receive pedometers plus a weekly prompt to set a step goal. They will participate in baseline and 3 months data collection.
Behavioral: TXT Me
text messages, physical activity, self determination theory, extrinsic motivation, intrinsic motivation, pedometers, walking, prompts
Experimental: pedometer + prompt + messages
Participants randomized to this arm will receive pedometers, weekly prompts, and 6 motivational text messages a week. They will participate in baseline and 3 months data collection.
Behavioral: TXT Me
text messages, physical activity, self determination theory, extrinsic motivation, intrinsic motivation, pedometers, walking, prompts
No Intervention: Control
Participants randomized to this group will participate in data collection only; they will not receive an intervention.

Detailed Description:
This research will develop an innovative intervention that promotes physical activity to 14-17 year olds (roughly high school aged youth). It is guided by Self Determination Theory and seeks to enhance adolescents' feelings of physical activity autonomy, competence, and relatedness, key psychological needs related to motivation to be physically active. The physical activity to be promoted is walking, which has broad appeal and can be performed as part of usual-day activities. Since youth are heavy users of cell phones and texting, the intervention will send theoretically-grounded text messages designed to enhance physical activity.
