MYSS-HYPE: A pilot study of contingency management for smoking cessation in young people with Borderline Personality Disorder features

All participants will undergo eight weeks of Contingency Management (CM). The CM will incentivise abstinence from cigarette smoking using cash reinforcement. Participants will attend 8 short (15 minute) face to face sessions in which they will report on their past week cigarette smoking and complete a carbon monoxide breath test (using a Smokerlyzer device). Participants submitting CO tests indicative of abstinence will receive a cash reward. The cash reward available at each session will increase with each consecutive week of abstinence, beginning at $25 (Week 1) and increasing in five-dollar increments up to a maximum of $60 (Week 8). Participants who have smoked in the past week will not receive a cash reward in their weekly session; furthermore, the potential reward for abstinence will reset at the starting amount ($25) the following week. In total, participants may receive up to $340 in cash rewards for verified abstinence throughout the trial. Session attendance checklists will be used to monitor adherence to the intervention and research procedures. Concomitant Therapy As patients of Orygen Specialist Program, participants will also continue to receive Treatment As Usual (TAU), i.e., standard psychosocial and psychiatric care delivered at the Orygen Specialist Program. TAU may include the opportunity to discuss cigarette smoking cravings and smoking cessation with their treating team (i.e., a mental health clinician and psychiatric registrar/consultant psychiatrist), in addition to a referral to Quitline. Participants may also undergo clinically indicated pharmacotherapy. Participants discharged from the Orygen Specialist Program, and enrolled at the Orygen Primary Services (Orygen Clinical Trials Unit) site will receive TAU at a mental health outpatient service.
