Intervention to Modify Habits: A Scoping Review.

Intervening to change clients' habits in the course of their everyday occupations could improve health. Habit formation interventions are an emerging area of science, however, and there is a need to better understand the current state of habit intervention research. The objective of this study is to examine the evidence related to habit formation interventions to modify health habits among adults. We performed a scoping review of peer-review articles published since January 1, 2008. The majority of the 18 studies included in the review were randomized control trials using one of two measures to assess habit change. Studies targeted a range of habits. Trial results were mixed but supportive of habit formation approaches. Through habit formation interventions, a range of everyday behaviors can become a habit. Occupational therapy professionals can use data and results generated from this review to inform the development of occupation-based habit formation treatments.
