NCT03184389

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Probability of being stressed.

    2 hour window after each micro-randomized intervention vs. no intervention event during first 10 days after quitting smoking

Secondary Outcomes (2)

  • First and all subsequent lapses in smoking cessation.

    10 days

  • Overeating episodes

    10 days

Study Arms (1)

Within-participant micro-randomization

OTHER

Each minute when participant is available is randomly assigned to either intervention (to practice a stress management exercise) vs. no intervention prompt. When intervention occurs, participant's smartphone vibrates and relaxation app opens, prompting performance of a relaxation exercise.

Behavioral: Prompt to use smartphone apps for stress management

Interventions

Study smartphone and software will be used to deliver intervention prompts to use stress management applications on the study smartphone at various times throughout the day, during at least 10 days of study participation. The delivery of prompts will be micro randomized to occur when participants are classified as stressed, and when participants are not classified as stressed. Headspace, a commercial stress management application, will be installed on the study smartphones. Thought Shakeup and Mood Surfing, stress management applications that are not commercially available, also will be installed on the study smartphones. These smartphone applications guide participants through stress management exercises that draw upon techniques from mindfulness, cognitive behavioral therapy, and acceptance and commitment therapy.

Data Sharing

IPD Sharing
Will share

Following completion of this study, a de-identified dataset, (i.e., containing no raw location/GPS information), will be generated and made available to interested researchers upon request. The dataset will be stripped of any information that could be linked back to the original data or to an individual participant. Prospective users of this dataset must sign a confidentiality agreement, requiring that they must get permission from the MD2K Center to share the data with anyone else. All external requests for data will be directed to Dr. Bonnie Spring and routed through the MD2K Center. Prospective investigators will submit a written proposal to the MD2K Executive Committee outlining the question they will investigate, the specific variables that they need to answer that question, their analytic plan for answering that question, and documentation of sufficient Institutional Review Board oversight. Investigators will also need to sign a confidentiality agreement.
