Norval J. Hickman; Kevin Delucchi; Judith J. Prochaska

Objective The Food and Drug Administration is considering regulation of menthol cigarettes. While persons with mental distress are known to smoke cigarettes at high rates, little is known about their use of menthol. The authors examined the association of psychological distress and menthol use in a national sample of adult smokers. Methods Data were from the 2008 and 2009 National Survey on Drug Use and Health. Past month smokers (N=24 157) were categorised for menthol or non-menthol use. Psychological distress was categorised as none/mild, moderate or severe on the Kessler six-item scale. Results The prevalence of menthol use was higher among individuals with severe psychological distress, women, young adults, African–Americans, Native Hawaiians/Pacific Islanders, persons with fewer years of education and lower income, and the unmarried and uninsured. In a multivariate model controlling for socio-demographic factors, smoking intensity and time to first cigarette, smokers with severe (adjusted OR (AOR) 1.23, 95% CI 1.04 to 1.46, p=0.02) but not moderate (AOR 1.03, 95% CI 0.92 to 1.15, p=0.58) psychological distress were significantly more likely to smoke menthols compared with smokers with none/mild distress. Conclusion An elevated prevalence of menthol use was found among persons with severe psychological distress, suggesting another group that could potentially benefit from the regulation of menthol cigarettes.

Norval J. Hickman; Kevin Delucchi; Judith J. Prochaska

INTRODUCTION This study examines the relation between tobacco use and cessation with lifetime and past year mental illness in a nationally representative sample of Blacks. METHODS This cross-sectional study analyzed nationally representative data from 3,411 adult Blacks participating in the 2001-2003 National Survey of American Life. Smoking prevalence and quit rates according to lifetime and past year Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition mental disorders were assessed by a modified version of the Composite International Diagnostic Interview. RESULTS Compared with those without mental illness, respondents with a lifetime, past year, or past month mental illness had a higher smoking prevalence (20.6%, 35.6%, 36.0%, and 45.4%, respectively) and lower quit rate (40.5%, 31.2%, and 26.2%, respectively). The odds of being a current smoker among Blacks with mental illness in their lifetime, past year, and past month, after adjusting for age, gender, education, poverty, and marital status were 1.76 (95% CI = 1.39-2.22), 1.57 (95% CI = 1.22-2.03), and 2.20 (95% CI = 1.56-3.12), respectively. Mental illness also was associated with heavier smoking. Blacks with past year mental illness represented 18.1% of the sample, yet consumed 23.9% of cigarettes smoked by Black smokers. Past year (odds ratio [OR] = 0.72, 95% CI = 0.53-0.97) and past month (OR = 0.54, 95% CI = 0.29-0.98) mental illness were associated with a lower odds of quitting for at least 1 year. CONCLUSIONS Findings indicate that mental illness is significantly associated with tobacco use in Blacks. Tobacco cessation interventions that address mental illness as a barrier to cessation are needed.

Treating Tobacco Dependence at the Intersection of Diversity, Poverty, and Mental Illness: A Randomized Feasibility and Replication Trial

Norval J. Hickman; Kevin Delucchi; Judith J. Prochaska

INTRODUCTION In an ethnically-diverse, uninsured psychiatric sample with co-occurring drug/alcohol addiction, we evaluated the feasibility and reproducibility of a tobacco treatment intervention. The intervention previously demonstrated efficacy in insured psychiatric and nonpsychiatric samples with 20.0%-25.0% abstinence at 18 months. METHODS Daily smokers, recruited in 2009-2010 from psychiatric units at an urban public hospital, were randomized to usual care (on-unit nicotine replacement plus quit advice) or intervention, which added a Transtheoretical-model tailored, computer-assisted intervention, stage-matched manual, brief counseling, and 10-week post-hospitalization nicotine replacement. RESULTS The sample (N = 100, 69% recruitment rate, age M = 40) was 56% racial/ethnic minority, 65% male, 79% unemployed, and 48% unstably housed, diagnosed with unipolar (54%) and bipolar (14%) depression and psychotic disorders (46%); 77% reported past-month illicit drug use. Prior to hospitalization, participants averaged 19 (SD = 11) cigarettes/day for 23 (SD = 13) years; 80% smoked within 30 minutes of awakening; 25% were preparing to quit. Encouraging and comparable to effects in the general population, 7-day point prevalence abstinence for intervention versus control was 12.5% versus 7.3% at 3 months, 17.5% versus 8.5% at 6 months, and 26.2% versus 16.7% at 12 months. Retention exceeded 80% over 12 months. The odds of abstinence increased over time, predicted by higher self-efficacy, greater perceived social status, and diagnosis of psychotic disorder compared to unipolar depression. CONCLUSIONS Findings indicate uninsured smokers with serious mental illness can engage in tobacco treatment research with quit rates comparable to the general population. A larger investigation is warranted. Inclusion of diverse smokers with mental illness in clinical trials is supported and encouraged.

Purpose. To describe effective retention strategies in a clinical trial with a high risk, low-income, and vulnerable patient population with serious mental illness. Design. Follow-up assessments were conducted for a randomized clinical tobacco treatment trial at 3, 6, and 12 months postbaseline. Initial follow-up rates of < 40% at 3 months led to implementation of proactive retention strategies including obtaining extensive contact information; building relationships with case managers and social workers; contacting jails and prisons; text messaging, e-mailing, and messaging via social networking sites; identifying appointments via electronic medical record; and field outreach to treatment facilities, residences, and parks. Setting. Large urban public hospital. Subjects. Participants were current smokers recruited from 100% smoke-free locked psychiatry units. Measures. Assessments covered demographics, substance use, and mental health functioning. Analysis. Retention rates were plotted over time in relation to key retention strategies. Chi-square and t-tests were used to examine participant predictors of retention at each follow-up. At the 12-month follow-up, the retention strategies that most frequently led to assessment completion were identified. Results. The sample (N = 100) was 65% male; age × = 39.5 years (SD = 11.3); 44% non-Hispanic white; 46% on Medicaid and 34% uninsured; 79% unemployed; and 48% unstably housed. Proactive retention strategies dramatically increased follow-up rates, concluding at 3 months = 82.65%, 6 months = 89.69%, and 12 months = 92.78%. Married and divorced/separated/widowed participants, those with higher income, and participants with alcohol or illicit drug problems had increased retention from 3- to 12-month follow-up. Conclusion. Follow-up rates improved as proactive methods to contact participants were implemented. Dedicated research staff, multiple methods, community networking, and outreach within drug treatment settings improved retention.

BACKGROUND AND OBJECTIVES De-normalization of smoking as a public health strategy may create shame and isolation in vulnerable groups unable to quit. To examine the nature and impact of smoking stigma, we developed the Internalized Stigma of Smoking Inventory (ISSI), tested its validity and reliability, and explored factors that may contribute to smoking stigma. METHODS We evaluated the ISSI in a sample of smokers with mental health diagnoses (N = 956), using exploratory and confirmatory factor analysis, and assessed construct validity. RESULTS Results reduced the ISSI to eight items with three subscales: smoking self-stigma related to shame, felt stigma related to social isolation, and discrimination experiences. Discrimination was the most commonly endorsed of the three subscales. A multivariate generalized linear model predicted 21-30% of the variance in the smoking stigma subscales. Self-stigma was greatest among those intending to quit; felt stigma was highest among those experiencing stigma in other domains, namely ethnicity and mental illness-based; and smoking-related discrimination was highest among women, Caucasians, and those with more education. DISCUSSION AND CONCLUSION Smoking stigma may compound stigma experiences in other areas. Aspects of smoking stigma in the domains of shame, isolation, and discrimination were related to modeled stigma responses, particularly readiness to quit and cigarette addiction, and were found to be more salient for groups where tobacco use is least prevalent. SCIENTIFIC SIGNIFICANCE The ISSI measure is useful for quantifying smoking-related stigma in multiple domains.

OBJECTIVE This investigation examined predictors of utilization of nicotine replacement therapy (NRT) during a smoke-free psychiatric hospitalization. METHODS Smokers (N=324) were recruited from smoke-free adult inpatient psychiatric units. Exploratory analyses examined correlates of NRT provision and utilization. RESULTS The prevalence of NRT use was 51% overall and was greater among patients offered NRT on admission (58%) versus later (34%), among patients with more severe depression and nicotine withdrawal, and among those who reported perceptions that NRT decreases nicotine withdrawal, provides a nicotine substitute, and helps with quitting smoking (p<.05, all comparisons). Although the ratio of nicotine patch dose to usual cigarettes per day was 1.2±.7, the ratio was negatively correlated with time to first cigarette (Spearmans ρ=-.30, p<.01), suggesting potential underdosing of more dependent smokers. CONCLUSIONS During smoke-free psychiatric hospitalizations, clinical management of nicotine withdrawal may be enhanced by offering patients NRT directly on admission, educating patients on the benefits of NRT, and increasing the dosage for more dependent smokers.

INTRODUCTION With a focus on protecting vulnerable groups from initiating and continuing tobacco use, the FDA has been considering the regulation of menthol in cigarettes. Using a large sample of adult smokers with serious mental illness (SMI) in the San Francisco Bay Area, we examined demographic and clinical correlates of menthol use, and we compared the prevalence of menthol use among our study participants to that of adult smokers in the general population in California. METHODS Adult smokers with SMI (N = 1,042) were recruited from 7 acute inpatient psychiatric units in the San Francisco Bay Area. Demographic, tobacco, and clinical correlates of menthol use were examined with bivariate and multivariate logistic regression analyses, and prevalence of menthol use was compared within racial/ethnic groups to California population estimates from the 2008-2011 National Survey on Drug Use and Health. RESULTS A sample majority (57%) reported smoking menthol cigarettes. Multivariate logistic regression analyses indicated that adult smokers with SMI who were younger, who had racial/ethnic minority status, who had fewer perceived interpersonal problems, and who had greater psychotic symptoms also had a significantly greater likelihood of menthol use. Smokers with SMI had a higher prevalence of menthol use relative to the general population in California overall (24%). CONCLUSIONS Individuals with SMI-particularly those who are younger, have racial/ethnic minority status, and have been diagnosed with a psychotic disorder-are vulnerable to menthol cigarette use. FDA regulation of menthol may prevent initiation and may encourage cessation among smokers with SMI.

Screening for understanding of research in the inpatient psychiatry setting.

Norval J. Hickman; Judith J. Prochaska; Laura B. Dunn

People with mental illness constitute a substantial proportion of smokers and an important population for smoking cessation research. Obtaining informed consent in this population is a critical ethical endeavor. We examined performance on a three-item instrument (3Q) designed to screen for understanding of several key elements of research: Study purpose, risks, and benefits. Patients were clinically diagnosed with primary unipolar depression (n = 40), a primary psychotic disorder (n = 32), both mood and psychotic disorders (n = 17), and primary bipolar disorder (n = 14). Among an ethnically diverse sample of 124 psychiatric inpatients approached for a smoking cessation trial, 107 (86%) performed adequately on the 3Q (i.e., obtained a score of at least 3 out of a possible 6). Patients were better able to identify the study risks and benefits than to describe the study purpose. The 3Q appears to be a useful tool for researchers working with vulnerable psychiatric patients.

Treating Smoking in Adults With Co-occurring Acute Psychiatric and Addictive Disorders.

Smita Das; Norval J. Hickman; Judith J. Prochaska

Objectives: Tobacco use is undertreated in individuals with psychiatric and substance use disorders (SUDs), with concerns that quitting smoking may compromise recovery. We evaluated outcomes of a tobacco intervention among psychiatric patients with co-occurring SUDs. Methods: Data from 2 randomized tobacco treatment trials conducted in inpatient psychiatry were combined; analyses focused on the subsample with co-occurring SUDs (n = 216). Usual care provided brief advice to quit and nicotine replacement therapy during the smoke-free hospitalization. The intervention, initiated during hospitalization and continued 6 months after hospitalization, was tailored to readiness to quit smoking, and added a computer-assisted intervention at baseline, and 3 and 6 months; brief counseling; and 10 weeks of nicotine replacement therapy after hospitalization. Outcomes were 7-day point prevalence abstinence from 3 to 12 months and past 30-day reports of alcohol and illicit drug use. Results: The sample consisted of 34% women, among which 36% were Caucasian, averaging 19 cigarettes/d prehospitalization; the groups were comparable at baseline. At 12 months, 22% of the intervention versus 11% of usual care participants were tobacco-abstinent (risk ratio 2.01, P = 0.03). Past 30-day abstinence from alcohol/drugs did not differ by group (22%); however, successful quitters were less likely than continued smokers to report past 30-day cannabis (18% vs 42%) and alcohol (22% vs 58%) use (P < 0.05), with no difference in other drug use. Conclusions: Tobacco treatment in psychiatric patients with co-occurring SUDs was effective and did not adversely impact recovery. Quitting smoking was associated with abstinence from alcohol and cannabis at follow-up. The findings support addressing tobacco in conjunction with alcohol and other drugs in psychiatric treatment.
