Contingency management for cigarette smokers with depressive symptoms

Area of Science:

• Addiction Medicine
• Behavioral Psychology
• Clinical Psychology

Background:

• Depressive symptoms are common in smokers, yet their impact on smoking cessation treatment outcomes, particularly with contingency management (CM), is understudied.
• Few studies have explored the interplay between depressive symptoms, treatment modality, and smoking cessation success.

Purpose of the Study:

• To investigate the relationship between treatment condition (cognitive behavioral treatment [CBT] vs. CBT + CM), baseline depressive symptoms, and smoking cessation outcomes.
• To examine how smoking status affects depressive symptoms during smoking cessation treatment.

Main Methods:

• Secondary analysis of 147 treatment-seeking smokers randomly assigned to CBT or CBT + CM.
• CBT delivered in 6-week group sessions; CM involved voucher-based incentives up to €300.
• Depressive symptoms assessed via Beck Depression Inventory-II; abstinence verified by cotinine and CO levels.

Main Results:

• The CBT + CM condition demonstrated superior smoking cessation efficacy compared to CBT alone, irrespective of baseline depressive symptoms.
• Higher levels of depressive symptoms were associated with fewer days of continuous smoking abstinence.
• Increased days of continuous smoking abstinence correlated with a reduction in depressive symptoms.

Conclusions:

• Combined CBT and CM is more effective for smoking cessation than CBT alone, benefiting even individuals with depressive symptoms.
• Integrating behavioral activation for mood management into smoking cessation services is recommended for patients with depression.
• Addressing both smoking and depressive symptoms concurrently can optimize treatment outcomes.
