Contingency management and motivational enhancement: a randomized clinical trial for college student smokers.

ABSTRACT:

Introduction

The efficacy of contingency-management (CM) and motivational enhancement therapy (MET) for college student smoking cessation was examined.

Methods

Nontreatment-seeking daily smokers (N = 110) were randomly assigned to 3 weeks of CM versus noncontingent reinforcement (NR) and to three individual sessions of MET versus a relaxation control in a 2 x 2 experimental design. Expired carbon monoxide (CO) samples were collected twice daily for 3 weeks. Participants earned 5 US dollars for providing each sample; additionally, those randomized to CM earned escalating monetary rewards based on CO reductions (Week 1) and smoking abstinence (Weeks 2-3).

Results

Compared with NR, CM resulted in significantly lower CO levels and greater total and consecutive abstinence during the intervention. Those in the CM and MET groups reported greater interest in quitting smoking posttreatment, but rates of confirmed abstinence at follow-up were very low (4% at 6-month follow-up) and did not differ by group.

Discussion

Findings support the short-term efficacy of CM for reducing smoking among college students. Future research should explore enhancements to CM in this population, including a longer intervention period and the recruitment of smokers who are motivated to quit.

Project description:ImportanceThere is a tension between clinician-led approaches to engagement in advance care planning (ACP), which are effective but resource-intensive, and self-administered tools, which are more easily disseminated but rely on ability and willingness to complete.ObjectiveTo examine the efficacy of computer-tailored print feedback (CTPF), motivational interviewing (MI), and motivational enhancement therapy (MET) on completion of a set of ACP activities, each as compared with usual care.Design, setting, and participantsThis randomized clinical trial was conducted from October 2017 to December 2020 via telephone contact with primary care patients at a single VA facility; 483 veterans aged 55 years or older were randomly selected from a list of patients with a primary care visit in the prior 12 months, with oversampling of women and people from minoritized racial and ethnic groups. Statistical analysis was performed from January to June 2022.InterventionsMailed CTPF generated in response to a brief telephone assessment of readiness to engage in and attitudes toward ACP; MI, an interview exploring ambivalence to change and developing a change plan; and MET, MI plus print feedback, delivered by telephone at baseline, 2, and 4 months.Main outcome and measuresSelf-reported completion of 4 ACP activities: communicating about views on quality vs quantity of life, assignment of a health care agent, completion of a living will, and submitting documents for inclusion in the electronic health record at 6 months.ResultsThe study included 483 persons, mean (SD) age 68.3 (8.0) years, 18.2% women and 31.1% who were people from minoritized racial and ethnic groups. Adjusting for age, education, race, gender, and baseline stage of change for each ACP, predicted probabilities for completing the ACP activities were: usual care 5.7% (95% CI, 2.8%-11.1%) for usual care, 17.7% (95% CI, 11.8%-25.9%; P = .003) for MET, 15.8% (95% CI, 10.2%-23.6%; P = .01) for MI, P = .01, and 10.0% (95% CI, 5.9%-16.7%; P = .18) for CTPF.Conclusions and relevanceThis randomized clinical trial found that a series of 3 MI and MET counseling sessions significantly increased the proportion of middle-aged and older veterans completing a set of ACP activities, while print feedback did not. These findings suggest the importance of clinical interaction for ACP engagement.Trial registrationClinicalTrials.gov Identifier: NCT03103828.

Project description:IntroductionDespite limitations in evidence, the current Clinical Practice Guideline advocates Motivational Interviewing for smokers not ready to quit. This study evaluated the efficacy of Motivational Interviewing for inducing cessation-related behaviors among smokers with low motivation to quit.DesignRandomized clinical trial.Setting/participantsTwo-hundred fifty-five daily smokers reporting low desire to quit smoking were recruited from an urban community during 2010-2011 and randomly assigned to Motivational Interviewing, health education, or brief advice using a 2:2:1 allocation. Data were analyzed from 2012 to 2014.InterventionFour sessions of Motivational Interviewing utilized a patient-centered communication style that explored patients' own reasons for change. Four sessions of health education provided education related to smoking cessation while excluding elements characteristic of Motivational Interviewing. A single session of brief advice consisted of brief, personalized advice to quit.Main outcomes measuresSelf-reported quit attempts; smoking abstinence (biochemically verified); use of cessation pharmacotherapies; motivation; and confidence to quit were assessed at baseline and 3- and 6-month follow-ups.ResultsUnexpectedly, no significant differences emerged between groups in the proportion who made a quit attempt by 6-month follow-up (Motivational Interviewing, 52.0%; health education, 60.8%; brief advice, 45.1%; p=0.157). Health education had significantly higher biochemically verified abstinence rates at 6 months (7.8%) than brief advice (0.0%) (8% risk difference, 95% CI=3%, 13%, p=0.003), with the Motivational Interviewing group falling in between (2.9% abstinent, 3% risk difference, 95% CI=0%, 6%, p=0.079). Both Motivational Interviewing and health education groups showed greater increases in cessation medication use, motivation, and confidence to quit relative to brief advice (all p<0.05), and health education showed greater increases in motivation relative to Motivational Interviewing (Cohen's d=0.36, 95% CI=0.12, 0.60).ConclusionsAlthough Motivational Interviewing was generally more efficacious than brief advice in inducing cessation behaviors, health education appeared the most efficacious. These results highlight the need to identify the contexts in which Motivational Interviewing may be most efficacious and question recommendations to use Motivational Interviewing rather than other less complex cessation induction interventions.Trial registrationThis study is registered at www.clinicaltrials.gov NCT01188018.
