Does self-control affect interventions to change alcohol, tobacco, and food consumption?

We conducted a systematic review to assess whether individual differences in self-control influence the effectiveness of interventions to change alcohol, tobacco, and food consumption. 54 studies were included in the review.

Our findings, published in Health Psychology Review, show that 22 studies (41%) did not report differences in intervention effectiveness by self-control, 18 (33%) reported interventions to be less effective in those with low self-control, and 14 (26%) reported interventions to be more effective in those with low self-control. This pattern of findings did not differ from chance. Click on the Read More button for further details on this study.
