Mood disturbance fails to resolve across 31 days of cigarette abstinence in women

Abstract

Smoking abstinence responses were characterized in 96 female smokers. Participants completed subjective state measures twice per week for 5 weeks and were then randomly assigned to a group required to abstain for 31 days or a control group that continued to smoke. Financial incentives for biochemically verified abstinence resulted in an 81% completion rate. Abstinence-related increases in depression, tension, anger, irritability, and appetite showed little tendency to return to prequit levels and remained significantly elevated above smoke-group levels. In contrast to psychological components of anxiety, physical components decreased to smoke group levels by the 2nd week of abstinence. Trait depression and neuroticism predicted larger increased abstinence-associated negative affect. The Big Five personality dimensions predicted variance not associated with depressive traits.
