Factorial Trial Testing Guided Thinking Tasks to Optimize a Physical Activity Intervention

Summary

The objective of this study is to optimize a novel, audio-recorded physical activity intervention that is scalable. Using principles of the Multiphase Optimization Strategy (MOST) framework, a full factorial study will test the unique and combined effects of different intervention components to identify which combination of components is optimal for increasing physical activity and mechanisms by which the components are or are not effective. This information will inform decisions about an optimal intervention package that is effective, efficient, and minimizes participant burden.

Conditions

• Physical Inactivity

Interventions

BEHAVIORAL

Episodic future thinking

Participants will listen to a guided thinking task directing them to think about themselves at a future, positive event and to imagine the event in vivid and specific detail.

BEHAVIORAL

Positive affect imagery

Participants will listen to a guided thinking task directing them to think about positive feelings and associations about physical activity in specific, personal, and positive detail.

BEHAVIORAL

Action planning

Participants will listen to a guided thinking task directing them to think about the remainder of their week and when, where, and how they plan to attain their remaining activity for the week.

BEHAVIORAL

High dose

Participants will listen to the audio-recording with the guided thinking tasks 5 times/week.

BEHAVIORAL

Recent thinking

Participants will listen to a guided thinking task directing them to think about a regular habit or activity they completed in the past week and to imagine that activity in specific and vivid detail.

BEHAVIORAL

Neutral imagery

Participants will listen to a guided thinking task directing them to imagine physical sensations (i.e., movements, muscles used) of a routine, daily activity (non-physical activity).

BEHAVIORAL

Low dose

Participants will listen to the audio-recording with the guided thinking tasks 1 time/week.
