Sense2Stop Mobile Sensor Data to Knowledge: Preliminary Study of the Effects of Wearable Sensors and Smartphone Apps on Real Time Stress and Smoking in Recently Quit Smokers

The aim of this research is to build systems that can recognize when people are stressed and
then provide them with relaxation prompts in the moment to reduce their likelihood of being
stressed, smoking, or overeating in the near future. Using these systems should help smokers
be more effective in their attempts to quit by reducing their tendency to lapse when they are
stressed or experiencing other negative moods or behaviors.

The purpose of this study is (1) to evaluate the feasibility of a just-in-time intervention
to decrease stress in recently quit smokers; and (2) to examine whether a just-in-time
adaptive intervention that decreases stress also reduces the near-term odds of a smoking
lapse.

The primary hypothesis of this study is that the administration of a prompt to perform a
relaxation exercise as compared to no prompt will lead to a lower likelihood of being
stressed in the subsequent two hours, and that this effect will be stronger when the prompt
is administered when the individual is stressed. The secondary hypothesis is that stress
episodes will predict the timing of smoking lapses. The third hypothesis is that
administration of a prompt to perform a relaxation exercise will reduce the odds of smoking
for the next two hours, and that this effect will be stronger when the prompt is administered
when the individual is stressed. The fourth (exploratory) hypothesis is that stress will
predict the timing of overeating episodes.

These data will also be used for developing automated risk prediction of smoking relapse, and
for developing decision rules for the timing of Just-In-Time-Adaptive Interventions (JITAIs).
