NCT03295409

Brief Summary

Evidence suggests that affirming the self can help people to make changes in their health behavior. Typically, people affirm a personally-important value, but evidence suggests that affirming the values of family ("familial self-affirmation") might exert stronger effects. The aim of the present study is to examine the effects of familial self-affirmation versus standard self-affirmation versus a control group on smoking cessation.
