Positive psychotherapy for smoking cessation: Treatment development,feasibility, and preliminary results

Low positive and high negative affect (NA) predict low rates of smoking abstinence among smokers making a quit attempt. Positive psychotherapy can both increase positive affect (PA) and decrease NA and, therefore, may be a useful adjunct to behavioral smoking counseling. The purpose of the present study was to assess the feasibility and acceptability of a positive psychotherapy for smoking cessation (PPT-S) intervention that integrates standard smoking cessation counseling with nicotine patch and a package of positive psychology interventions. We delivered PPT-S to 19 smokers who were low in PA at baseline. Rates of session attendance and satisfaction with treatment were high, and most participants reported using and benefiting from the positive psychology interventions. Almost one-third of the participants (31.6%) sustained smoking abstinence for six months after their quit date. Future studies to assess the relative efficacy of PPT-S compared to standard smoking cessation treatment are warranted.     

Nicotine withdrawal in smokers with current depressive disorders undergoing intensive smoking cessation treatment.

The authors investigated withdrawal in smokers with current threshold and subthreshold depressive disorders (N = 21) who were participating in a pilot study of intensive counseling interventions for smoking cessation. The majority of participants (67%) were taking antidepressants when they entered the trial. Withdrawal symptoms were compared in prolonged abstainers versus nonabstainers across a 12-week treatment period and at the 3-month follow-up assessment visit. Prolonged abstinence was associated with an increase in positive affect and a decrease in depressive symptoms and craving over time. Nonabstinence was associated with little overall change in these variables from treatment onset to the 3-month follow-up. At the 3-month follow-up, 44% of prolonged abstainers were in complete remission of their baseline depressive disorders, compared with 0% remission among nonabstainers. Findings suggest that within the context of an intensive smoking cessation intervention, some smokers with current depressive disorders may experience significant improvement in affective and craving symptoms. Findings also suggest that abstinence may be associated with improvement in affect.     

Quality of life after quitting smoking and initiating aerobic exercise

Quitting smoking and aerobic exercise each improve health. Although smokers may be concerned that quitting smoking will reduce their quality of life (QOL), recent research has shown that cessation is associated with QOL benefits. Elements of smoking cessation interventions, such as exercise, may contribute to changes in QOL. However, it is unknown whether initiating exercise in the context of smoking cessation is associated with greater or different effects on QOL than smoking cessation alone. The current study is a secondary analysis of data from a randomized trial (n = 61) of an exercise intervention for smoking cessation. We hypothesized that smoking abstinence and engagement in exercise would have positive, additive effects on QOL at end-of-treatment, 6- and, 12-month follow-ups. Sedentary adult smokers were randomized to the exercise intervention or a health education control (HEC) group. Additionally, all participants received smoking cessation counseling and nicotine patches. Data were analyzed using actual engagement in exercise, rather than group assignment as a proxy for exercise engagement, because some HEC participants also began exercising. Abstinence was positively associated with higher total and physical health QOL at follow-up. Exercise was not associated with total QOL and only marginally associated with physical health QOL, but was positively related to overall sense of well-being. Emphasizing that smoking cessation is associated with higher QOL may help motivate smokers to initiate quit attempts.     

A randomized controlled trial of contingency management for smoking cessation in substance use treatment patients

Background/ObjectiveContingency management (CM) is one of the most effective interventions for smokers with substance use disorder (SUD), and no empirical assessment of its long-term efficacy has been conducted so far in a real-world context. The objectives were: (1) examine the additive effectiveness of CM on cognitive-behavioral treatment (CBT) for smoking cessation, and (2) examine the relationship between smoking cessation and substance use abstinence.MethodA total of 80 participants (75.8% males; M_age = 45.31; SD = 9.64) were assigned to two smoking cessation treatments: CBT or CBT+CM. A set of generalized estimating equations were conducted to examine the effect of treatment condition on smoking outcomes, as well as the effect of smoking status on substance abstinence.ResultsAdding CM to CBT for smoking cessation improved tobacco abstinence rates at the end-of-treatment (p = .049). Tobacco abstinence rates declined over time (p = .012), but no significant effects of treatment condition were observed across follow-ups (p = .260). Smoking cessation was not significantly related to substance abstinence (p ≥ .488).ConclusionsCM facilitates early abstinence in smokers with SUD, although effects subside after treatment termination. The lack of association between smoking abstinence and substance use suggests no jeopardizing effects as a result of quitting smoking.     

Testing a self-determination theory intervention for motivating tobacco cessation: supporting autonomy and competence in a clinical trial.

A longitudinal randomized trial tested the self-determination theory (SDT) intervention and process model of health behavior change for tobacco cessation (N = 1006). Adult smokers were recruited for a study of smokers' health and were assigned to intensive treatment or community care. Participants were relatively poor and undereducated. Intervention patients perceived greater autonomy support and reported greater autonomous and competence motivations than did control patients. They also reported greater medication use and significantly greater abstinence. Structural equation modeling analyses confirmed the SDT process model in which perceived autonomy support led to increases in autonomous and competence motivations, which in turn led to greater cessation. The causal role of autonomy support in the internalization of autonomous motivation, perceived competence, and smoking cessation was supported.     

Effects of a televised smoking cessation intervention among low-income and minority smokers

In November 1985, a television smoking cessation program was broadcast for 20 days on the noon and 9 p.m. news. Smokers in West Garfield Park, an inner-city impoverished area of Chicago, were randomly assigned either to a comprehensive intervention or to a no-intervention control condition. Although 100,000 self-help manuals had been distributed throughout Chicago, none of the controls in this low-income area had obtained a manual. The intervention consisted of providing the smokers a self-help manual, the televised broadcast, weekly support meetings, and supportive phone calls. At a 4-month follow-up, 20% of treatment participants were abstinent compared to 9% of controls. The results indicated that intensive supplementary opportunities enhanced participation by low-income smokers in a media smoking cessation program.     

A randomized trial comparing the effects of self-help materials and proactive telephone counseling on teen smoking cessation.

We conducted a 2-arm randomized trial to test the efficacy of self-help materials with or without proactive telephone counseling to increase cessation among teen smokers. Teen smokers (N = 402) recruited from 11 shopping malls and 1 amusement park in the southeastern United States were randomized to 1 of 2 groups: written self-help material plus video; or written self-help material, video, and telephone counseling. Cessation rates based on 7-day point-prevalent abstinence for the self-help and counseling arms were 11% and 16%, respectively (p = .25), at 4 months postbaseline and 19% and 21%, respectively (p = .80), at 8 months postbaseline. Sustained abstinence, reflecting 7-day abstinence at both time points, in the self-help and counseling arms was 7% and 9% (p = .59). Results suggest that minimal self-help cessation approaches that target youth have comparable success to that shown among adult smokers. However, refinements in telephone-counseling approaches may be needed to achieve the success observed in adult populations.     

Comparing intervention outcomes in smokers treated for single versus multiple behavioral risks.

This study examined treatment outcomes among smokers with single versus multiple behavioral risks. Data were drawn from smokers (N = 2,326) participating in 3 population-based, multibehavioral studies targeting cigarette smoking, high-fat diets, and high-risk sun exposure. Outcomes were compared for participants at risk for smoking only (13%), smoking plus 1 additional risk factor (37%), and smoking plus 2 additional risk factors (50%). The smoking only group tended to be female, older, more educated, lighter smokers, in the preparation stage of change for smoking, with more previous quit attempts and longer periods of abstinence. At 12 and 24 months follow-up, treatment of 1 or 2 coexisting risk factors did not decrease the effectiveness of smoking cessation treatment, and treatment for the coexisting factors was effective.     

Mood Management Mail Intervention Increases Abstinence Rates for Spanish-Speaking Latino Smokers

A self-administered mood management intervention program for smoking cessation provided through the mail to Spanish-speaking Latinos resulted in a 23% abstinence rate at 3 months compared to an 11% abstinence rate for a smoking cessation guide alone. Participants (N = 136) were randomly assigned to receive either the cessation guide (the Guía), or the Guía plus a mood management intervention (Tomando Control de su Vida) presented in writing and in audiotape format. At 3 months after random assignment, 16 out of 71 of those assigned to the Guía-plus-mood management condition reported being abstinent (not smoking for at least 7 days) compared to 7 out of 65 in the Guía-only condition (z = 1.8; p = .04, one-tailed). Moreover, those with a history of major depressive episodes, but not currently depressed, reported an even higher abstinence rate in the Guía-plus-mood management condition, compared to the Guía-only condition (31 vs. 11%, z = 1.8, p = .04, one-tailed). We conclude that the mood management mail intervention substantially increases abstinence rates, especially for those with a history of major depressive episodes.     

Putting It on the Line: Telephone Counseling for Adolescent Smokers

Adolescent smokers need cessation help, but the question of how best to intervene remains unanswered. This article describes the empirically validated protocol of an established, well‐utilized adolescent telephone counseling program for smoking cessation, tailored to adolescent developmental needs and shown to increase clients' 6‐month prolonged abstinence rate significantly. Clinical issues addressed include client assessment, motivation, self‐efficacy, familial and social support, planning, coping, relapse‐sensitive call scheduling, and self‐image. Counselor training considerations are also discussed.     

The Contemplation Ladder: validation of a measure of readiness to consider smoking cessation

Presents evidence for the validity of the Contemplation Ladder, a measure of readiness to consider smoking cessation. Analyses of data collected from more than 400 smokers at two worksites before and during a 10-month intervention indicate that Ladder scores were significantly associated with reported intention to quit, number of previous quit attempts, perceived co-worker encouragement to quit, and socioeconomic status. Ladder scores predicted subsequent participation in programs designed to educate workers about their smoking habit and its contingent risks. The Ladder did not predict biochemically validated abstinence of 24 hr or more. To assess its ability to distinguish between groups known a priori to differ in readiness, we administered the Ladder to 36 participants in a clinic-based smoking cessation program. As predicted, clinic patients scored significantly higher than the workers on the Ladder. The importance of distinguishing between smokers at the lowest stages of readiness to quit is discussed.     

Secondary smoking prevention in a university setting: a randomized comparison of an experiential, theory-based intervention and a standard didactic intervention for increasing cessation motivation.

OBJECTIVE: College may represent an untapped opportunity to reach the growing number of student smokers who are at risk of progressing toward regular smoking. The aim of this study was to test the efficacy of a theory-based experiential intervention for increasing motivation to quit smoking and reducing smoking behavior. DESIGN: This study used a 3-arm, randomized design to examine the efficacy of an experiential secondary prevention intervention. The control groups included a traditional didactic smoking intervention and an experiential intervention on nutrition. MAIN OUTCOME MEASURES: The 2 primary dependent variables were change in self-reported intention to quit smoking, measured pre- and postintervention, and change in smoking behavior over the month following the intervention. RESULTS: As hypothesized, the experiential smoking intervention was more effective than either control group in increasing immediate motivation to quit, but the effect was found only among female participants. At 1-month follow-up, both smoking interventions produced higher rates of smoking cessation and reduction than did the nutrition control condition. CONCLUSION: Findings support the potential efficacy of an intensive experiential intervention for female smokers.     

Demonstration of an Integrated Treatment for Smoking Cessation and Anxiety Symptoms in People With HIV: A Clinical Case Study

Despite high rates of co-occurring tobacco use and anxiety symptoms and disorders among persons with HIV, evidence-based interventions for these individuals are not yet available. The present study sought to evaluate an integrated treatment model addressing smoking cessation and anxiety sypmtoms among HIV-positive smokers. Treatment was an 8-week intervention integrating a standard smoking cessation protocol (i.e., cognitive-behavioral therapy [CBT], nicotine replacement therapy) with CBT for anxiety. Inclusion criteria were 18–65 years of age, ≥ 10 cigarettes/day, State–Trait Anxiety Inventory [STAI-T] score of > 39, and moderate motivation (i.e., ≥ 5 out of 10 on a 10-point Likert scale) to quit smoking. Primary outcomes included scores on the Anxiety Sensitivity Index (ASI) and cigarettes smoked per day. Self-reported abstinence was biochemically verified by carbon monoxide breath analysis. Three male participants (mean age 49.3, SD = 9.1) completed through 2-month follow-up. At baseline all participants reported smoking an average of 20 cigarettes per day. Two participants quit smoking and maintained abstinence by the 2-month follow-up, and demonstrated a reduction in ASI scores. Participant 3 continued to smoke but at a reduced rate. Participants’ response to cognitive and behavioral strategies (e.g., creating balanced thoughts, interoceptive exposures) will be discussed. Clinical lessons learned include use of a flexible approach to cognitive restructuring, use of imaginal and in vivo exposures in session to better prepare patients for homework practice, and flexibility in delivering the treatment in an individual or group format. This clinical presentation provides preliminary support for the feasibility and initial effectiveness of an integrated treatment to reduce anxiety symptoms and aid in smoking cessation in anxious, HIV-positive smokers.     

Internet‐based self‐tailored deposit contracts to promote smoking reduction and abstinence

Deposit contracting may reduce costs and increase efficacy in contingency management interventions. We evaluated two Internet‐based deposit contract arrangements for smoking. In Experiment 1, nine participants deposited self‐selected amounts that could be earned back for meeting goals. During treatment, participants were reimbursed for breath samples with less than or equal to 6 parts per million carbon monoxide and met the criterion for 47% of samples compared to 1% during baseline. In Experiment 2, 10 participants’ deposits were matched up to $50. No samples met the criterion during baseline but 41.5% met it during treatment. The average deposit was $82 in Experiment 1 and $49 in Experiment 2. Participants rated the intervention favorably and sample submission rates were high. These experiments suggest that Internet‐based self‐tailored deposits are acceptable, feasible, and can promote brief reduction and abstinence in some smokers. Future research should investigate individual and intervention factors that affect long‐term cessation and uptake of deposit contracts.     

Patient-Informed Treatment Development of Behavioral Smoking Cessation for People With Schizophrenia

The objective of this study was to use qualitative methodology to tailor and refine an existing smoking cessation intervention for the population of people who use cigarettes and are diagnosed with schizophrenia, schizoaffective, or psychotic disorder. Successive cohort design methodology was used to iteratively modify the treatment in response to qualitative participant, therapist, and consultant feedback on the intervention. Qualitative methodology for participant feedback included analysis of semistructured interviews with participants, visualization of app utilization data, and stakeholder feedback from study therapists and consultants. Using the successive cohort design, a tailored multicomponent mobile health smoking cessation intervention was developed. The intervention included mobile contingency management (i.e., financial compensation for confirmed abstinence from smoking), pharmacotherapy for smoking cessation, cognitive-behavioral counseling sessions, and the Stay Quit app for relapse prevention. Two cohorts (N = 13) were completed in the study; after each cohort, the treatment protocol was revised. The intervention is described, as well as the qualitative findings from each cohort and subsequent changes made to the intervention based upon patient and provider feedback. Metrics of patient engagement included treatment adherence (40% in Cohort 1 and 63% in Cohort 2). Both participants and therapists reported that the intervention was helpful. Over one third of participants self-reported abstinence at posttreatment. Since qualitative methodology is often underutilized in mental health treatment development, this study demonstrates the utility of the successive cohort design for treatment development of behavior change interventions for at-risk, vulnerable populations.     

The patient exit interview as an assessment of physician-delivered smoking intervention: a validation study.

In evaluating the efficacy of physician-delivered counseling interventions for health behavior changes such as smoking cessation, a major challenge is determining the degree to which interventions are implemented by physicians. The Patient Exit Interview (PEI; J. Ockene et al., 1991) is a brief measure of a patient's perception of the content and quantity of smoking cessation intervention received from his or her physician. One hundred eight current smokers seen in a primary care clinic completed a PEI following their physician visit. Participants were 45% male, 95% Caucasian, with a mean age of 42 years and an average of 22 years of smoking. The PEI correlated well with a criterion measure of an audiotape assessment of the physician-patient interaction (r = .67, p < .001). When discrepancy occurred, in general it was due to patients' over-reporting of intervention as compared with the criterion measure. Implications and limitations of these findings are discussed.     

Effects of internet-based voucher reinforcement and a transdermal nicotine patch on cigarette smoking

Nicotine replacement products are commonly used to promote smoking cessation, but alternative and complementary methods may increase cessation rates. The current experiment compared the short-term effects of a transdermal nicotine patch to voucher-based reinforcement of smoking abstinence on cigarette smoking. Fourteen heavy smokers (7 men and 7 women) completed the four 5-day phases of the study: baseline, patch treatment, voucher treatment, and return to baseline. The order of the two treatment phases was counterbalanced across participants. In the patch treatment condition, participants wore a 14-mg transdermal nicotine patch every day. In the voucher treatment condition, participants received vouchers contingent on abstinence from smoking, defined as producing carbon monoxide (CO) readings of < or =4 parts per million. Participants e-mailed two video clips per day showing them breathing into a CO monitor and the resulting CO reading to clinic staff. In the voucher treatment, 24% of samples were negative, and 5% of samples were negative in the patch treatment. Results suggest that contingent vouchers were more effective than transdermal nicotine patches in promoting abstinence.     

Reduction of anxiety sensitivity in relation to nicotine withdrawal symptoms during smoking cessation: an examination among successful quitters

Anxiety sensitivity has been implicated as a potential risk factor for post-quit withdrawal symptoms. The present study examined relations between the extent of change in anxiety sensitivity and the course of nicotine withdrawal symptoms experienced during the initial two weeks of a quit attempt among treatment-seeking smokers. The sample consisted of 29 adult daily smokers (34% female; M_age = 47.7, SD = 13.1) who successfully quit and maintained their abstinence. After adjusting for the effects of gender, treatment condition, use of nicotine replacement therapy, nicotine dependence, alcohol use problems, baseline levels of anxiety sensitivity, and reductions in negative affect, greater reductions in anxiety sensitivity were related to faster decreases in withdrawal symptoms. The current data suggest that there may be merit to employ anxiety sensitivity reduction methods for the management of emergent withdrawal symptoms in smoking cessation treatment.     

Depression vulnerability moderates the effects of cognitive behavior therapy in a randomized controlled trial for smoking cessation

Several clinical trials have tested the hypothesis that smoking cessation treatments with a mood management component derived from cognitive behavior therapy (CBT) for depression would be specifically effective for depression-vulnerable smokers, with mixed results. This trial addressed methodological concerns with some of the previous studies to clarify whether depression vulnerability does in fact moderate CBT smoking cessation outcome. The study compared 8-session group CBT with a time-matched comparison group condition in a sample of 100 cigarette smokers randomized to treatment condition. Each treatment group was led by one of 7 American University clinical psychology graduate students; therapists were crossed with treatment conditions. Outcome (7-day point prevalence abstinence) was evaluated 1 month and 3 months after quit date. Baseline self-reported depression vulnerability (sample median split on the Depression Proneness Inventory) moderated treatment response, such that more depression-prone smokers fared better in CBT whereas less depression-prone smokers fared better in the comparison condition. These results may have implications for determining when to use CBT components in smoking cessation programs.     

Effects of biochemical validation of self-reported cigarette smoking on treatment success and on misreporting abstinence

Many investigators have reported that cigarette smokers who are trying to quit often falsely report being abstinent at the end of treatment. Unfortunately, much of the previous research designed to investigate this problem has been flawed, making the results difficult to interpret. We attempted to avoid these flaws and to investigate the measurement of alveolar carbon monoxide (CO) levels to validate self-reported smoking rates at the end of treatment. Participants in behavioral cessation clinics were randomly assigned to one of three conditions that varied in timing of exposure to information regarding CO measurement: at the beginning of treatment (demonstration of CO measurement, discussion of smoking effects on CO levels, and notification that individual CO levels would be measured at the conclusion of the clinic), at the end of treatment (demonstration, discussion, and notification of CO measurement prior to self-reports of smoking levels), or at the end of treatment (demonstration and discussion of CO measurement subsequent to self-reports of smoking levels). CO levels of all participants were measured at the end of treatment after they reported their current smoking levels. Only 16% of self-reports of abstinence were not verified by CO measurement. Smokers who observed the CO demonstration at the beginning of treatment were significantly more likely than the other two groups to achieve abstinence at the end of treatment and significantly less likely to misreport abstinence. Clinical and research implications of these results are discussed.
