The Natural Trajectory of Smoking Cessation Among Cancer Patients Who Want to Quit "On Their Own": A Mixed-Methods, Longitudinal Study

INTRODUCTION

Many cancer patients who smoke cigarettes want to quit. Unfortunately, many of these cancer patients prefer to quit without the aid of pharmacotherapy or behavioral counseling. The teachable moment of cancer diagnosis might still position these cancer patients to make meaningful changes in their smoking behavior, but no study has documented the trajectory of smoking cessation outcomes among cancer patients who want to quit "on their own." This study aimed to fill this gap in the literature.

METHODS

In this mixed-methods, longitudinal study, 35 cancer patients who declined tobacco treatment because of the desire to quit "on their own" provided data via three surveys and 1-2 semi-structured interviews. The observation period spanned 60 days. Participants were recently diagnosed at and recruited from outpatient cancer clinics.

RESULTS

Participants were mostly female (68.57%), White, non-Hispanic (85.71%), unemployed due to disability (57.14%), and rural residents (54.29%). Across time, 43.76% of participants achieved 50% smoking reduction, 21.88% achieved 3-day floating abstinence, 18.75% achieved 7-day floating abstinence, and 12.50% achieved 30-day point-prevalence abstinence. Key themes that emerged from the interviews centered on intention and confidence to quit and types of tobacco treatment used/received.

CONCLUSIONS

This study with cancer patients who desired to quit smoking without assistance found some evidence of quit success, but success waned as criteria grew more stringent. Results showed participants' initial intention to quit unassisted was quite strong, as few reported tobacco treatment use. Interventions to increase the uptake of evidence-based tobacco treatment among cancer patients are sorely needed.

IMPLICATIONS

The preference to quit smoking without assistance is common among cancer patients, even given lack of evidence supporting its effectiveness. This study is the first to explore the trajectory of smoking cessation outcomes among cancer patients who desire to quit without assistance. These data can be used to develop interventions to increase the uptake of tobacco treatment and increase quit success among cancer patients.

Understanding cancer patients' desire to quit tobacco without assistance: A mixed-methods study

While many cancer patients who use tobacco try to quit post-diagnosis, some prefer to quit without using tobacco treatment, despite evidence against unassisted quit attempts. This study aimed to understand the rationale for some cancer patients' desire to quit tobacco without assistance. Thirty-five adult cancer patients who currently used tobacco and declined tobacco treatment because of the desire to quit unassisted provided data via a standardized questionnaire and a semi-structured interview. The sample was predominately White, non-Hispanic (85.71%) and female (68.57%). The most common cancer site was gynecological. Key themes that emerged from the interviews were: self-reliance, willpower, social norms, and negative attitudes toward tobacco treatment. The most frequently endorsed barrier to tobacco treatment was "I know others who have quit without tobacco treatment" (82.86%). This study with cancer patients identified affective, cognitive, and personality factors related to quitting unassisted, and social and systemic reasons to not use tobacco treatment.

Holding your liquor: Comparison of alcohol-induced psychomotor impairment in drinkers with and without alcohol use disorder

BACKGROUND

Behavioral tolerance to alcohol underscores the widely accepted notion that individuals who regularly drink alcohol become less sensitive to its impairing effects. However, previous research assessing alcohol-induced impairment in humans has primarily focused on social drinkers. This has limited our understanding of the nature and extent of behavioral tolerance among heavier drinkers, such as those with alcohol use disorder (AUD).

METHODS

Data from three cohorts of the Chicago Social Drinking Project were evaluated to examine the acute effects of alcohol on psychomotor performance across the breath alcohol curve in light drinkers (LDs; n = 86), heavy drinkers (HDs; n = 208), and individuals with AUD (AUDs; n = 103). Before and at several intervals after ingesting either alcohol (0.8 g/kg, peak BrAC = 0.09 g/dL) or placebo in two random-order laboratory sessions, participants completed a test of fine motor coordination (Grooved Pegboard), a test of perceptual-motor processing (Digit Symbol Substitution Task), and a self-reported survey of perceived impairment. Sixty individuals with AUD completed a third session with a very high dose of alcohol (1.2 g/kg, peak BrAC = 0.13 g/dL).

RESULTS

The AUD and HD groups, relative to the LD group, perceived less impairment and demonstrated greater behavioral tolerance to an intoxicating dose of alcohol, exhibited by reduced peak impairment and a quicker return to baseline performance on psychomotor measures. Among individuals with AUD who consumed the very high dose, impairment was more than double that following the usual high dose, and it exceeded the impairment among LDs following the usual high dose.

CONCLUSIONS

In this sample of young adult drinkers, relative to the LD group, those with heavier drinking patterns (AUD and HD groups) showed greater behavioral tolerance to 0.8 g/kg alcohol, a dose typically associated with a binge drinking episode. However, when challenged with a very high alcohol dose commensurate with high-intensity drinking, individuals with AUD showed substantial psychomotor impairment.

Courage to Quit® rolling group: Implementation in an urban medical center in primarily low-income Black smokers

BACKGROUND

Continuous "rolling" tobacco group treatments may help reduce cessation disparities by increasing access among underserved people who smoke cigarettes. We evaluated the implementation of a rolling enrollment adaptation of an evidence-based tobacco treatment group intervention, Courage to Quit®-Rolling (CTQ®-R).

METHODS

The 4-session CTQ®-R incorporating psychoeducation, motivational enhancement, and cognitive behavioral skills was evaluated by examining feasibility and preliminary program outcomes with a pre-post design using the SQUIRE method in a sample of 289 primarily low-income, Black people who smoke. Feasibility was measured by examining program retention. Paired t-tests evaluated changes in behavioral intentions and knowledge about smoking cessation and differences in average daily cigarettes smoked from first to last session attended.

RESULTS

CTQ-R was feasible to implement in an urban medical center program enrolling primarily low-income Black people who smoke, with 52% attending at least 2 sessions and 24% completing the full program. Participants demonstrated improvements in knowledge of smoking cessation strategies and confidence in quitting (ps < .004). Preliminary effectiveness analyses showed a 30% reduction in average daily cigarette use, with group completers reporting greater reduction than non-completers.

CONCLUSIONS

CTQ®-R is feasible and showed preliminary effectiveness for increasing knowledge about stop smoking skills and reducing cigarette smoking.

IMPLICATIONS

A rolling enrollment smoking group treatment is feasible and may be effective among people who smoke who face historical and systemic barriers to tobacco treatment engagement. Evaluation in other settings and over longer periods of time is needed.
