It is being tested with a wide spectrum of healthcare outcomes. The SMART design was developed to allow researchers to build optimal adaptive interventions, and this design is rapidly gaining popularity and use among scientists. In a SMART design, researchers start with an initial intervention, and then change/augment it over time based on response to the initial treatment.
Sequential multiple assignment randomized trial trial#
A sequential multiple assignment randomized trial (SMART) provides an effective way to test differential response to alternative treatment options that make up adaptive interventions. While each intervention has proven efficacy, individual participant response to the intervention varies drastically.Īdaptive interventions specify a sequence of decision rules to determine why, how, and when treatment delivery should be changed based on patient characteristics or response to an initial treatment. Women who fail to increase and maintain their physical activity with physical activity monitors alone or physical activity monitors coupled with text messages may benefit from augmented treatment, including personal telephone calls that provide individual social support and/or group meetings that provide peer social support. Another intervention with demonstrated physical activity efficacy includes motivational text messages coupled with physical activity monitors. Fitbit) as a motivational tool for self-monitoring have shown promising results in increasing physical activity in women. Recent interventions using physical activity monitors (e.g. Physical activity monitors, motivational text messages, behavioral group meetings and motivational personal calls have been tested in interventions to improve physical activity.
Lower levels of self-efficacy, as well as needing different types of social support, can also affect physical activity in women.
Women also experience barriers to being more physically active outside of work including home demands, neighborhood safety, and health concerns. Low levels of physical activity can be exacerbated by large amounts of sedentary behavior imposed in many worksites, which poses as a significant barrier as over 56% of women are employed.
Despite this important fact, slightly over half of women in the United States continue to not meet aerobic physical activity guidelines. Insufficient physical activity continues to be a risk factor for cardiovascular disease, which is a leading cause of death among women.
