Task persistence predicts smoking cessation in smokers with and without schizophrenia

Area of Science:

• Psychology
• Psychiatry
• Behavioral Science

Background:

• Achieving and maintaining smoking abstinence requires cognitive and behavioral coping strategies.
• Task persistence, the ability to persist in difficult tasks, is crucial for managing smoking cues, urges, and withdrawal symptoms.

Purpose of the Study:

• To investigate if task persistence prospectively predicts smoking cessation.
• To examine this relationship in a mixed sample of smokers with and without schizophrenia.

Main Methods:

• A prospective study involving 71 smokers with schizophrenia or schizoaffective disorder and 78 nonpsychiatric smokers.
• Task persistence was measured using a mirror-tracing task before the quit date.
• Tobacco use was tracked for 6 months post-quit date using generalized estimating equations.

Main Results:

• Task persistence significantly predicted smoking cessation.
• This prediction remained valid after controlling for psychiatric diagnosis, nicotine dependence, and self-efficacy to quit.
• The predictive value of task persistence was consistent across smokers with and without schizophrenia.

Conclusions:

• Task persistence is an important factor in successful smoking cessation.
• Interventions aimed at enhancing task persistence may be beneficial for smoking cessation protocols, including for individuals with schizophrenia.
