Physical Activity Promotion Clinical Trial
Official title:
Evaluating Motivational Interviewing and Habit Formation to Enhance the Effect of Activity Trackers on Healthy Adults' Activity Levels: A Randomized Intervention
Wearable fitness monitors are increasingly popular but the actual utility of these devices for promoting physical activity behavior is unknown. The purpose is to examine the efficacy of the Fitbit monitor for previously inactive individuals when used alone or following brief training in behavior change strategies and techniques. Psychosocial factors will be assessed and changes in physical activity will be monitored over three months to determine the efficacy of this intervention and to better understand individual differences in effectiveness.
The objective for this pilot study is to determine the efficacy of the Fitbit Charge wearable
fitness monitor alone or in combination with additional behavior change strategies for
increasing physical activity in inactive adults. A secondary objective is to assess the
influence of psychosocial factors (e.g. self-efficacy, self-regulation, habit formation) on
the effectiveness of this type of behavior change intervention. The central hypothesis is
that use of the Fitbit will increase physical activity from baseline and that adding
additional strategies will enhance this effect. This hypothesis is based on previous research
demonstrating that continuous self- monitoring (using wearable technology) is effective in
promotion of weight-loss in overweight and obese adults. This objective will be addressed
through pursuing the following specific aims.
Aim 1: To determine the efficacy of using the Fitbit to increase physical activity behaviors
and improve health markers in inactive adults. The working hypothesis is that wearing a
Fitbit for 3 months will increase physical activity and improve health markers from baseline
to follow-up in inactive adults.
Aim 2: To compare the efficacy of the Fitbit alone to the Fitbit in combination with behavior
change strategies for increasing physical activity and improving psychosocial factors in
inactive adults. The working hypothesis is that using the Fitbit along with behavior change
strategies will lead to greater improvements in physical activity and psychosocial factors
(self- motivation, self-regulation, self-efficacy, and social support) than using the Fitbit
alone.
Aim 3: To assess the influence of individual differences in psychosocial variables on changes
in physical activity over the intervention. The working hypothesis is that higher levels of
self- motivation, self-regulation, self-efficacy, and social support at baseline will be
predictive of greater improvements in physical activity over the intervention, regardless of
group assignment.
