Pilot Study of Contingency Management for Smoking Cessation

NCT03015597 | Completed

• 1 other identifier: 171709
• Study Type: interventional
• Target: 40
• Locations: 1 country

Brief Summary

The purpose of this study is to see whether contingency management (CM) can be successfully added as an adjunct treatment to standard stop smoking services in outpatients undergoing treatment for opiate addiction. Forty tobacco smoking patients undergoing treatment for opiate addiction will be stratified to a CM intervention for either smoking abstinence or attendance at the clinic, whilst also receiving usual stop smoking services cessation treatment. The intervention will run for five weeks and participants will be followed up six months after the beginning of the study.

Study Arms (2)

Contingency Management: smoking

EXPERIMENTAL

Contingency Management: smoking Participants receive rewards contingent on biochemical verification of tobacco smoking abstinence

Behavioral: Contingency Management

Contingency Management: attendance

PLACEBO COMPARATOR

Contingency Management: attendance Participants receive rewards contingent on attending the stop smoking clinic (independent of smoking status)

Behavioral: Contingency Management

Interventions

Contingency Management BEHAVIORAL

Contingency management is a behavioural intervention based on the principals of operant conditioning that is widely used in the addictions field. At the most basic level, contingency management works by providing rewards as reinforcement for desired behaviours. In the current study, the desired behaviours are either attendance at the clinic and abstinence from tobacco smoking, or just attendance at the clinic, dependent on the arm of the trial that participants are randomised to. Participants in the experimental condition will receive shopping vouchers for attending the clinic and providing a breath CO recording of \<10ppm. Participants in the control condition will receive shopping vouchers for attending the clinic, regardless of their breath CO recording results.

Contingency Management: attendance; Contingency Management: smoking
