Brief Summary

Problematic anger is a strong predictor of failed attempts at smoking cessation. The investigators proposed study seeks to evaluate whether a novel 8-session computerized anger-reduction treatment improves quit rates among smokers. Smokers with elevated trait anger will be administered transdermal nicotine patch therapy and either anger-reduction treatment or a control intervention. They will be assessed throughout treatment and up until three months after a scheduled mid- treatment quit date. The investigators propose to test whether, compared to the control condition, the anger-reduction treatment will lead to: 1) greater reductions in anger and 2) greater abstinence rates at post-cessation and at follow-up assessments. The investigators will also test whether changes in anger-related symptoms account for group differences in abstinence rates.

Anger Reduction Treatment

EXPERIMENTAL

The treatment consists of eight 30-minute IBM sessions. Participants will be presented with ambiguous scenarios and asked imagine themselves in these situations. In the first task, the scenario will be followed by a benign interpretation of the situation. Participants will answer a comprehension question designed to have participants endorse this benign interpretation. In the second task, participants will be presented with a word denoting an interpretation with either a negative/hostile or positive/benign connotation. Following this word, an ambiguous scenario will appear. Participants will indicate whether the word and the scenario were related. They will receive feedback training them to endorse positive interpretations and reject negative interpretations.

Behavioral: Anger Reduction Treatment

Control Condition

PLACEBO COMPARATOR

Participants assigned to the control condition will complete eight computerized sessions consisting of psychoeducation on healthy behaviors (i.e., topics of exercise, diet, hygiene, social support, healthy activities, and sleep, taken from protocols developed from our ongoing research). These participants will also view relaxing videos consisting of brief guided meditation instructions, pictures of nature scenes, and soft music. These sessions (psychoeducation and relaxing videos) will be matched for time with the active treatment condition, lasting 30 minutes each.

Behavioral: Control Condition

Interventions

Eight 30-minute sessions of interpretation modification to reduce angry interpretation biases.

Anger Reduction Treatment

Eight 30-minute sessions of informative videos on healthy living and relaxation videos.

Control Condition
