Expectations May Influence Smoking Withdrawal Effects - Dr. Hendricks

Expectations for smoking cessation meaningfully predict smoking withdrawal effects, determines Peter S. Hendricks, PhD, assistant professor in the Department of Health Behavior in the School of Public Health.

Examining the influence of participants’ expectations for withdrawal symptoms such as craving and negative mood, this study observed adult smokers in two counterbalanced experimental sessions involving either 16 hours of abstinence or smoking as usual.

Participants completed three scales of the Smoking Abstinence Questionnaire—which was developed by Dr. Hendricks and his team to measure smokers' expectations for the cessation process—related to withdrawal at the beginning of the study. These expectations proved robust predictors of participants’ withdrawal experience.
