A Comparison of Autonomous Regulation and Negative Self-Evaluative Emotions as Predictors of Smoking Behavior Change Among College Students

This study compared autonomous self-regulation and negative self-evaluative emotions as predictors of smoking behavior change in college student smokers (N=303) in a smoking cessation intervention study. Although the two constructs were moderately correlated, latent growth curve modeling revealed that only autonomous regulation, but not negative self-evaluative emotions, was negatively related to the number of days smoked. Results suggest that the two variables tap different aspects of motivation to change smoking behaviors, and that autonomous regulation predicts smoking behavior change better than negative self-evaluative emotions

Assessing the Integrity of Motivational Interviewing Interventions: Reliability of the Motivational Interviewing Skills Code

The motivational interviewing skills code (MISC) was used to review 86 audiotaped interactions between clinicians and patients participating in a smoking cessation intervention. Intraclass correlations (ICCs) were completed for two of the MISC elements: global evaluations and behavior counts. Results indicate 75% of the global ratings yielded ICCs in the good to excellent range, while only 44% of the behavior counts yielded this level of accuracy. Adherence scores were created to form overall ratings of clinician adherence to using motivational interviewing and 80% of these competence measures yielded ICCs in the good to excellent range. Specific recommendations regarding modifications for the MISC are suggested based on the data presented

Evaluation of an adapted version of the diabetes prevention program for low- and middle-income countries: A cluster randomized trial to evaluate “Lifestyle Africa” in South Africa

Background Low-and middle-income countries (LMICs) are experiencing : major increases in diabetes and cardiovascular conditions linked to overweight and obesity. Lifestyle interventions such as the United States National Diabetes Prevention Program (DPP) developed in high-income countries require adaptation and cultural tailoring for LMICs. The objective of this study was to evaluate the efficacy of Lifestyle Africa, an adapted version ; italicsshouldnotbeusedfore of the DPP tailored for an underresourced community in South Africa compared to usual care. Methods and findings Participants were residents of a predominantly Xhosa-speaking urban township of Cape Town, South Africa characterized by high rates of poverty. Participants with body mass index (BMI) ≥ 25 kg/m2 who were members of existing social support groups or “clubs” receiving health services from local nongovernmental organizations (NGOs) were enrolled in a cluster randomized controlled trial that compared Lifestyle Africa (the intervention condition) to usual care (the control condition). The Lifestyle Africa intervention consisted of 17 video-based group sessions delivered by trained community health workers (CHWs). Clusters were randomized using a numbered list of the CHWs and their assigned clubs based on a computer-based random allocation scheme. CHWs, participants, and research team members could not be blinded to condition. Percentage weight loss (primary outcome), hemoglobin A1c (HbA1c), blood pressure, triglycerides, and low-density lipoprotein (LDL) cholesterol were assessed 7 to 9 months after enrollment. An individual-level intention-to-treat analysis was conducted adjusting for clustering within clubs and baseline values. Trial registration is at ClinicalTrials.gov (NCT03342274). Between February 2018 and May 2019, 782 individuals were screened, and 494 were enrolled. Participants were predominantly retired (57% were receiving a pension) and female (89%) with a mean age of 68 years. Participants from 28 clusters were allocated to Lifestyle Africa (15, n = 240) or usual care (13, n = 254). Fidelity assessments indicated that the intervention was generally delivered as intended. The modal number of sessions held across all clubs was 17, and the mean attendance of participants across all sessions was 61%. Outcome assessment was completed by 215 (90%) intervention and 223 (88%) control participants. Intent-to-treat analyses utilizing multilevel modeling included all randomized participants. Mean weight change (primary outcome) was −0.61% (95% confidence interval (CI) = −1.22, −0.01) in Lifestyle Africa and −0.44% (95% CI = −1.06, 0.18) in control with no significant difference (group difference = −0.17%; 95% CI = −1.04, 0.71; p = 0.71). However, HbA1c was significantly lower at follow-up in Lifestyle Africa compared to the usual care group (mean difference = −0.24, 95% CI = −0.39, −0.09, p = 0.001). None of the other secondary outcomes differed at follow-up: systolic blood pressure (group difference = −1.36; 95% CI = −6.92, 4.21; p = 0.63), diastolic blood pressure (group difference = −0.39; 95% CI = −3.25, 2.30; p = 0.78), LDL (group difference = −0.07; 95% CI = −0.19, 0.05; p = 0.26), triglycerides (group difference = −0.02; 95% CI = −0.20, 0.16; p = 0.80). There were no unanticipated problems and serious adverse events were rare, unrelated to the intervention, and similar across groups (11 in Lifestyle Africa versus 13 in usual care). Limitations of the study include the lack of a rigorous dietary intake measure and the high representation of older women. Conclusions In this study, we found that Lifestyle Africa was feasible for CHWs to deliver and, although it had no effect on the primary outcome of weight loss or secondary outcomes of blood pressure or triglycerides, it had an apparent small significant effect on HbA1c. The study demonstrates the potential feasibility of CHWs to deliver a program without expert involvement by utilizing video-based sessions. The intervention may hold promise for addressing cardiovascular disease (CVD) and diabetes at scale in LMICs. Copyright: © 2022 Catley et al.

Analysis of Smoking Patterns and Contexts Among College Student Smokers

Many who smoke in college do so infrequently and smoking conditions are not well-understood. We examined smoking patterns among college fraternity and sorority members (N=207) from a Midwestern university in three successive fall semesters in 2006–2008. Participants completed calendar-assisted retrospective assessments of 30-day smoking at up to 5 assessment points over 96 days. Overall smoking rates declined over the course of each semester and higher smoking on weekends was observed, with more variability among daily smokers. The most frequent categories of events to cue recall of smoking were socializing, work, and school. Findings can be used to target prevention efforts

Timeline Follow-Back Versus Global Self-Reports of Tobacco Smoking: A Comparison of Findings With Non-Daily Smokers

Methods assessing non-daily smoking are of concern because biochemical measures can not verify self-reports beyond 7 days. This study compares two self-reported smoking measures for non-daily smokers. A total of 389 college students, (48% female, 96% white, mean age of 19) smoking between 1 and 29 days out of the past 30, completed computer assessments in three cohorts with the order of administration of the measures counterbalanced. Values from the two measures were highly correlated. Comparisons of Timeline Follow-Back (TLFB) with the global questions for the total sample of non-daily smokers yielded statistically significant differences (p\u3c.001), albeit small, between measures with the TLFB resulting on average in 2.38 more total cigarettes smoked out of the past 30 days, 0.46 less smoking days, and 0.21 more cigarettes smoked per day. Analyses by level of smoking showed that the discordance between the measures differed by frequency of smoking. Global questions of days smoked resulted in frequent reporting in multiples of five days, suggesting digit bias. Overall the two measures of smoking were highly correlated and equally effective for identifying any smoking in a 30-day period among non-daily smokers

Strategies to Recruit and Retain College Smokers in Cessation Trials

Techniques to recruit and retain college fraternity and sorority members who reported past 30-day smoking into a cessation trial are described. Recruitment efforts included relationship-building, raffles, and screening survey administration during existing meetings. Surveys were administered to 76% (n = 3,276) of members in 30 chapters, 79% of eligible members agreed to participate, and 76% of those completed assessments and were enrolled in the trial (n = 452). The retention rate was 73%. Retention efforts included cash incentives, flexible scheduling, multiple reminders, chapter incentives, and use of chapter members as study personnel. Retention was not related to demographic, behavioral, or group characteristics. The strategies of partnership, convenience, and flexibility appear effective and may prove useful to investigators recruiting similar samples

Motivational Interviewing for Smoking Cessation in College Students: A Group Randomized Controlled Trial

Objective—To examine the efficacy of four individually-delivered Motivational Interviewing counseling sessions for smoking cessation versus a matched intensity comparison condition. Method—From 2006–2009, students attending college in the Midwest smoking at least 1 of 30 days were recruited regardless of their interest in quitting. 30 fraternities and sororities were randomized, resulting in 452 participants. Results—No significant differences were found for 30-day cessation between treatment and comparison at end of treatment (31.4% vs 28%, OR=1.20, 95% CI .72,1.99) or at follow-up (20.4% vs 24.6%, OR=.78, 95% CI .50,1.22). Predictors of cessation at follow-up, regardless of condition, included more sessions attended (OR 1.2, 95% CI 1.1,1.8) and more cigarettes smoked in 30 days at baseline (OR 4.7, 95% CI 2.5,8.9). The odds of making at least one quit attempt were significantly greater for those in the smoking group at end of treatment (OR 1.75, 95% CI 1.11,2.74) and followup (OR 1.66, 95% CI 1.11,2.47). Modeling showed reduction in days smoked for both groups. At end of treatment, more frequent smokers in the treatment condition had greater reductions in days smoked. Conclusion—Motivational Interviewing for smoking cessation is effective for increasing cessation attempts and reducing days smoked in the short run

Adherence to Principles of Motivational Interviewing and Client Within-Session Behavior

The purpose of this study was to examine whether counselor adherence to Motivational Interviewing (MI) principles was associated with more productive within-session client behavior in a smoking cessation trial for African American smokers. For these analyses 89 baseline counseling sessions of the trial were audiotaped and coded using the Motivational Interviewing Skill Code (MISC). Counselor adherence indicators included a global subjective rating of MI adherence and the frequency of MI-consistent and MI-inconsistent counselor behaviors described in the MISC. Indicators of productive client behaviors included global subjective ratings of within-session client functioning and counselor-client interaction, as well as the frequency of statements by the client favorable toward changing behavior (“change talk”) and resistant regarding changing behavior (“resist-change talk”). Results provided support for the principles of MI. Counselor adherence indexed by both the global subjective rating and MI-consistent behavior frequency was significantly positively associated with global ratings of within-session client functioning and counselor-client interaction, as well as more change talk

Motivational Interviewing for encouraging quit attempts among unmotivated smokers: Study protocol of a randomized, controlled, efficacy trial.

Abstract Background Although the current Clinical Practice Guideline recommend Motivational Interviewing for use with smokers not ready to quit, the strength of evidence for its use is rated as not optimal. The purpose of the present study is to address key methodological limitations of previous studies by ensuring fidelity in the delivery of the Motivational Interviewing intervention, using an attention-matched control condition, and focusing on unmotivated smokers whom meta-analyses have indicated may benefit most from Motivational Interviewing. It is hypothesized that MI will be more effective at inducing quit attempts and smoking cessation at 6-month follow-up than brief advice to quit and an intensity-matched health education condition. Methods/Design A sample of adult community resident smokers (N = 255) who report low motivation and readiness to quit are being randomized using a 2:2:1 treatment allocation to Motivational Interviewing, Health Education, or Brief Advice. Over 6 months, participants in Motivational Interviewing and Health Education receive 4 individual counseling sessions and participants in Brief Advice receive one brief in-person individual session at baseline. Rigorous monitoring and independent verification of fidelity will assure the counseling approaches are distinct and delivered as planned. Participants complete surveys at baseline, week 12 and 6-month follow-up to assess demographics, smoking characteristics, and smoking outcomes. Participants who decide to quit are provided with a self-help guide to quitting, help with a quit plan, and free pharmacotherapy. The primary outcome is self-report of one or more quit attempts lasting at least 24 hours between randomization and 6-month follow-up. The secondary outcome is biochemically confirmed 7-day point prevalence cessation at 6-month follow-up. Hypothesized mediators of the presumed treatment effect on quit attempts are greater perceived autonomy support and autonomous motivation. Use of pharmacotherapy is a hypothesized mediator of Motivational Interviewing’s effect on cessation. Discussion This trial will provide the most rigorous evaluation to date of Motivational Interviewing’s efficacy for encouraging unmotivated smokers to make a quit attempt. It will also provide effect-size estimates of MI’s impact on smoking cessation to inform future clinical trials and inform the Clinical Practice Guideline.
