Does one size fit all African American smokers? The moderating role of acculturation in culturally specific interventions.

There is a consensus that interventions for ethnic minority populations should be culturally specific (CS). A previous study found that although African American smokers indicated a preference for CS self-help materials over standard materials, several outcomes were superior for the standard information (Webb, 2008). The current study reports on a priori analyses that tested level of acculturation as a moderating variable for the efficacy of CS interventions in a sample of low-income African Americans. Participants (N = 182) completed the African American Acculturation Scale--Revised before receiving a CS smoking cessation guide or a standard guide. As hypothesized, level of acculturation predicted evaluations of the intervention content, readiness to quit smoking, and 24-hr point prevalence abstinence at the 3-month follow-up. Lower levels of acculturation (i.e., more engagement in traditional African American culture) predicted a preference for CS materials and greater readiness to quit smoking after receiving the CS guide. Yet, among participants who were less acculturated, 24-hr abstinence was greater after receiving the standard guide. Overall, these findings emphasize that individual differences in levels of acculturation to the dominant culture affect receptivity to CS written interventions. Intragroup differences should be considered prior to the provision of CS interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reasons for quitting smoking among low-income African American smokers.

The psychometric characteristics of the Reasons For Quitting scale (RFQ) were assessed among a sample of African American smokers with low income (N?=?487). The intrinsic and extrinsic scales and their respective subscales were replicated. As hypothesized, higher levels of motivation were associated significantly, in patterns that supported the measure's construct validity, with advanced stage of readiness to quit smoking, greater perceived vulnerability to health effects of smoking, and greater social support for cessation. On the basis of the present study, the RFQ might best predict short-term cessation among older and female smokers. Refinement of the RFQ is needed to assess intrinsic motivators other than health concerns and to identify salient motivators for young and male smokers.

Long-term psychological sequelae of smoking cessation and relapse.

The authors examined whether smoking cessation and relapse were associated with changes in stress, negative affect, and smoking-related beliefs. Quitters showed decreasing stress, increasing negative health beliefs about smoking, and decreasing beliefs in smoking's psychological benefits. Quitters became indistinguishable from stable nonsmokers in stress and personalized health beliefs, but quitters maintained stronger beliefs in the psychological benefits of smoking than stable nonsmokers. Relapse was not associated with increases in stress or negative affect. However, relapsers increased their positive beliefs about smoking and became indistinguishable from smokers in their beliefs. For quitters, decreased stress and negative beliefs about smoking may help maintain successful cessation. However, for relapsers, declining health risk perceptions may undermine future quit attempts.

Factors associated with participation, attrition, and outcome in a smoking cessation program at the workplace.

Of 66 24–58 yr old smokers in 2 worksites, 67% participated in a smoking cessation program. 55% completed the program. Of those, 29% had quit smoking by posttest, and 17% were abstinent at the 6-mo follow-up. Different variables predicted participation, attrition, and outcome. Significant predictors of smokers who participated were length of cessation in previous abstinence attempts, number of years they smoked, and belief regarding personal vulnerability in contracting a smoking-related disease. Levels of pretest carbon monoxide and attitudes regarding adoption of smoking restrictions in the worksite predicted attrition. Posttest cessation was related to nicotine levels of cigarette brand smoked at pretest and pretest beliefs regarding postcessation weight gain. Abstinence at the 6-mo follow-up was predicted by number of co-workers who smoked and pretest concerns related to postcessation weight gain.

A self-help smoking cessation program for inner-city African Americans: results from the Harlem Health Connection Project

The authors develop and test a culturally sensitive, low-intensity smoking cessation intervention for low-socioeconomic African Americans. African American adult smokers were randomly assigned to receive either a multicomponent smoking cessation intervention comprising a printed guide, a video, and a telephone booster call or health education materials not directly addressing tobacco use. The results of the study were mixed. Although no significant effects were observed for the entire treatment cohort, the results of post hoc analyses suggest that culturally sensitive self-help smoking cessation materials plus a single phone contact can produce short-term cessation rates similar to those reported for majority populations. This conclusion should be tempered by the low completion rate for the booster call and several design limitations of the study.     

Promoting smoking cessation among cancer patients: a behavioral model

The smoking cessation clinical practice guideline recently published by the Agency for Health Care Policy and Research (AHCPR) summarizes current knowledge on smoking cessation treatments. Among its recommendations, the guideline encourages physicians to motivate patients who indicate that they are not yet ready to quit smoking. Because medical training typically emphasizes pharmacologic rather than behavioral treatment, we believe that physicians caring for cancer patients may benefit from more extensive instruction in motivating patients to quit smoking. This article describes how a contemporary theoretical approach, the transtheoretical model of change, can be used to promote behavioral change. Multiple studies, primarily in the field of smoking cessation, provide strong empiric support for use of this model in clinical practice. The model consists of five stages of smoking cessation that describe different levels of readiness to quit: precontemplation, contemplation, preparation, action, and maintenance. A diagnostic tool is presented, and specific smoking cessation counseling strategies are suggested for each stage of change. Implications for the use of the model by physicians who counsel and treat smokers are discussed.     

Strategies for smoking cessation

Smoking cessation strategies should be geared to the target group's level of motivation to quit, and degree of tobacco addiction. Motivational interventions (e.g. media campaigns) aim to encourage more people to try to stop smoking. Treatment interventions (e.g. nicotine replacement) aim to increase the chances of a quit attempt being successful. In populations which have already been saturated by motivational interventions, the overall effect of adding further motivational interventions may be rather small, and possibly non-existent in heavy smokers. As a population's smoking prevalence declines, so the balance of interventions should shift from motivational to treatment approaches. Nicotine replacement is an effective smoking cessation aid and should form the basis for treating moderate to heavy smokers. There may be a case for the development of more specialist clinics to treat motivated but addicted smokers and train health professionals how to apply effective smoking cessation methods as part of their routine work.     

Tailored Interventions for Motivating Smoking Cessation: Using Placebo Tailoring to Examine the Influence of Expectancies and Personalization.

The present study examined mechanisms underlying the effectiveness of tailored interventions for motivating smoking cessation. The study used a placebo-tailoring design to test whether the efficacy of tailoring was due, in part, to personalized features in addition to the theoretically based content. Two hundred forty adult smokers were randomized to 1 of 3 conditions: standard booklet, minimally personalized booklet, or extensively personalized booklet. The interventions varied in their degree of ostensible tailoring, yet the actual smoking-related content of the booklets was identical. A dose-response relationship was hypothesized, with the greatest apparent tailoring producing the most positive outcomes. This pattern was found for evaluation of the booklets, with trends for readiness to change and self-efficacy increases. Moreover, as hypothesized, the effect of the interventions on readiness was moderated by participants' expectancies about tailoring. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Impact of expenditures for veterinary services and medical supplies on dairy farm productivity and profitability

OBJECTIVES: This study was undertaken to explore smoking patterns and attitudes that influence smoking cessation and relapse among African Americans. METHODS: Baseline data from eight Community Intervention Trial for Smoking Cessation (COMMIT) sites were analyzed. RESULTS: Compared with Whites, African Americans who smoke less than 25 cigarettes per day were 1.6 times more likely to smoke within 10 minutes of awakening (a behavioral indicator of nicotine dependence), adjusting for education, age, and gender (OR = 1.2 for heavier smokers). African Americans reported a stronger desire to quit smoking and reported serious quit attempts in the past year. African Americans favored tobacco restrictions (they were 1.8 times more likely than Whites to view smoking as a serious community problem, 1.7 times more likely to favor restrictions on cigarette vending machines, and 2.1 times more likely to prohibit smoking in their car). African Americans were lighter/moderate, menthol smokers. CONCLUSIONS: African Americans find smoking socially unacceptable and are strongly motivated to quit, but their "wake-up" smoking may indicate high nicotine dependence, making abstinence difficult even for lighter smokers.     

Predictors of quitting and dropout among women in a clinic-based smoking cessation program.

Most cessation studies assume that dropouts are smokers. Instead, the authors analyzed these outcomes separately using multinomial regression to model the relative risk of quitting versus continued smoking and dropping out. Female (N = 281) smokers were randomly assigned to a 12-week smoking cessation program plus either a 3-times-per-week exercise program or a contact control wellness program. Higher body mass index and longer prior quit attempts predicted cessation. Self-efficacy was associated with a lower likelihood of dropout. Greater nicotine dependence and lower education predicted continued smoking or dropout versus quitting among exercisers. Patterns of smoking, dropping out, and quitting between Weeks 5 and 12 were different between exercisers and controls. Dropouts should be considered as a separate category from smokers.

Characteristics of smokers who attempt to quit and of those who recently succeeded

Although a high percentage of smokers attempt to quit each year, success rates are low. Thus, public health strategies must not only convince some smokers to attempt cessation, but also improve the success rate among other smokers already motivated to quit. Specific cessation strategies may be required for smokers in these two groups. This study compares sociodemographic and health behavior characteristics of smokers who have and have not attempted to quit and of those who recently succeeded. To determine whether these characteristics vary for men and women, we stratified analyses on gender. Data were obtained from random sample health surveys conducted 1981-1982 and 1983-1984 in two New England communities. Analyses include data on 2,086 respondents who reported smoking cigarettes in the previous year. Men and women were equally likely both to attempt cessation and to quit. Except for an inverse association with age, attempting to quit was not associated with sociodemographic variables. In men and women, attempts were associated with encouraging others to quit and attempting to increase exercise. Successful cessation attempts were associated with not living with a smoker in women; marital status, attempted weight loss, and increased age in men; and with efforts to increase exercise in both men and women. These characteristics could be useful in targeting smokers who attempt to quit, but fail. Improving the success rate in this group could greatly reduce smoking prevalence in the community.     

Expectancy priming of smoking cessation messages enhances the placebo effect of tailored interventions.

Objective: Previous research (Webb, Simmons, & Brandon, 2005) suggested that smokers' reactions to self-help materials were more positive if they believed that the materials had been personally tailored to their individual characteristics and if they held expectancies that tailored interventions are superior to standard, or generic, interventions. The authors' objective in the current study was to replicate and extend this research by testing the efficacy expectancy priming before intervention delivery. Design: In a 2 × 2 factorial experiment, 210 smokers (M = 23 cigarettes/day) recruited from the community (62% female; 92% Caucasian; mean age = 49) were randomly assigned to 1 of 4 conditions: placebo-tailored intervention/no priming, placebo-tailored intervention/priming, standard intervention/no priming, or standard intervention/priming. The tailoring-related expectancies of participants' in the priming conditions were primed before they were presented with the respective intervention booklets. Main Outcome Measures: Content evaluations, readiness to quit smoking, cessation self-efficacy, smoking-related knowledge, and progress toward quitting (behavior changes). Assessments occurred by mail at baseline and at 1-month postintervention. Results: Similar to the earlier study, the placebo-tailored booklets produced superior evaluations and smoking-related cognitive and behavioral changes. Moreover, the pretreatment expectancy priming successfully altered participants' tailoring-related expectancies and also produced superior evaluations and outcomes. Conclusion: Findings support a causal role of tailoring-related expectancies on the efficacy of tailored interventions and suggest that interventions can be enhanced via expectancy priming.

Implicit and explicit attitudes predict smoking cessation: Moderating effects of experienced failure to control smoking and plans to quit.

The current study tested implicit and explicit attitudes as prospective predictors of smoking cessation in a Midwestern community sample of smokers. Results showed that the effects of attitudes significantly varied with levels of experienced failure to control smoking and plans to quit. Explicit attitudes significantly predicted later cessation among those with low (but not high or average) levels of experienced failure to control smoking. Conversely, however, implicit attitudes significantly predicted later cessation among those with high levels of experienced failure to control smoking, but only if they had a plan to quit. Because smoking cessation involves both controlled and automatic processes, interventions may need to consider attitude change interventions that focus on both implicit and explicit attitudes.

Desire and efforts to quit smoking among cigarette smokers in Wisconsin

This research studied the desire and attempts of cigarette smokers in Wisconsin to quit smoking. Data were based on the 1993 Wisconsin Division of Health's Behavioral Risk Factor Surveillance System (BRFSS). Among the 23% of respondents who were current smokers, 79% said they wanted to quit smoking and 60% said they had quit smoking for a day or more in the preceding year. High rates of wanting to quit and having tried to quit were found in all demographic subgroups of smokers studied. Compared to lighter smokers, heavy cigarette smokers (20 or more cigarettes per day) were less likely to have tried quitting in the past year, but were almost as likely to want to quit. These results demonstrate the great demand for smoking cessation services among smokers in Wisconsin and support for efforts to increase the use and effectiveness of these interventions.     

Matched and mismatched interventions with young adult smokers: Testing a stage theory.

This experiment tested the transtheoretical model (J. O. Prochaska & C. C. DiClemente, 1983) of smoking cessation by matching or mismatching interventions to smokers in a particular stage. The interventions were tested against a no-intervention condition with 92 college-aged daily smokers in the precontemplation stage of change. The stage-matched intervention asked smokers to think more about quitting smoking; the stage-mismatched intervention provided action-oriented activities typically used for those ready to quit smoking. The results failed to support the value of matching interventions to a smoker's stage of change. Instead, more smokers who received the action intervention tried to quit smoking. Matching interventions to an individual's current stage may be less important than the transtheoretical model suggests. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Chorioretinal damage caused by the excision of choroidal neovascularization

BACKGROUND: In recent years many longitudinal studies have examined the predictors of smoking acquisition. However, only a few studies have focused on the precursors of smoking cessation. The current study is one of the first concentrating on longitudinal predictors of young people's smoking cessation. METHODS: Subjects were 215 smokers ages 14-15 years who were reinterviewed 3 years later. These smokers were allocated to four groups based on their motivation to quit and actual quitting behavior at the last wave. Independent variables were smoking-specific cognitions, social influences, and aspects of smoking habits. RESULTS: Univariate comparisons between the four groups showed that those with a positive attitude toward smoking and lower self-efficacy were less likely to be motivated to quit 3 years later. No long-term effects of environmental influences were found. Aspects of smoking habits, such as intensity and frequency of smoking, and the context of cigarette use affected the motivation to quit. Logistic regression analyses were conducted to examine differences in predictors between the groups in more detail. These analyses revealed that differences mainly in attitudes and self-efficacy affected whether subjects were absolutely not motivated to quit or had actually quit 3 years later. Differences in smoking behavior affected the allocation to the more closely related groups (e.g., preparing versus quitting). CONCLUSIONS: Adolescents' motivation to quit is affected by smoking-related cognitions and habitual factors. More research is needed to decide whether the relation between intensity and frequency of smoking and the likelihood to quit later on should be interpreted in terms of differences in smoking initiation or in terms of preparation to quit.     

Randomized controlled trial of behavioral activation smoking cessation treatment for smokers with elevated depressive symptoms.

Objective: Depressive symptoms are associated with poor smoking cessation outcomes, and there remains continued interest in behavioral interventions that simultaneously target smoking and depressive symptomatology. In this pilot study, we examined whether a behavioral activation treatment for smoking (BATS) can enhance cessation outcomes. Method: A sample of 68 adult smokers with mildly elevated depressive symptoms (M = 43.8 years of age; 48.5% were women; 72.7% were African American) seeking smoking cessation treatment were randomized to receive either BATS paired with standard treatment (ST) smoking cessation strategies including nicotine replacement therapy (n = 35) or ST alone including nicotine replacement therapy (n = 33). BATS and ST were matched for contact time and included 8 sessions of group-based treatment. Quit date was assigned to occur at Session 4 for each treatment condition. Participants completed a baseline assessment; furthermore, measures of smoking cessation outcomes (7-day verified point-prevalence abstinence), depressive symptoms (Beck Depression Inventory–II; Beck, Steer, & Brown, 1996), and enjoyment from daily activities (Environmental Reward Observation Scale; Armento & Hopko, 2007) were obtained at 1, 4, 16, and 26 weeks post assigned quit date. Results: Across the follow-ups over 26 weeks, participants in BATS reported greater smoking abstinence (adjusted odds ratio = 3.59, 95% CI [1.22, 10.53], p = .02) than did those in ST. Participants in BATS also reported a greater reduction in depressive symptoms (B = ?1.99, SE = 0.86, p = .02) than did those in ST. Conclusions: Results suggest BATS is a promising intervention that may promote smoking cessation and improve depressive symptoms among underserved smokers of diverse backgrounds.

The theory of planned behavior and smoking cessation.

A sample of 84 smokers attending health promotion clinics in a primary care setting completed questionnaires that assessed the main constructs of the theory of planned behavior, perceived susceptibility, and past cessation attempts. Regression analyses revealed that intention to quit smoking was primarily predicted by perceived behavioral control and perceived susceptibility. At 6-month follow-up, the making of a quit attempt was predicted by intention and the number of previous quit attempts, whereas the length of the quit attempt was predicted solely by the length of the longest recent quit attempt. The results suggest that interventions should focus on perceptions of susceptibility and control to increase smokers' motivation to quit. However, further work is required to identify the social cognitive variables that ensure that initial quit attempts are translated into longer term abstinence.

Is weight gain after smoking cessation inevitable?

Weight gain after smoking cessation was studied in a naturalistic setting where (1) all smokers quit and (2) risk factors for postcessation weight gain were modified. Participants were 332 military recruits (227 men, 105 women), 86 of whom were smokers who quit during 6 weeks of basic training. Results showed no significant weight changes for smokers who quit. Pretest smoking rates and feat of weight gain were unrelated to changes in weight. Results suggest that an intensive program that limits access to alcohol and foods that are high in fat and that increases physical activity can attenuate weight gain after smoking cessation.

The striatum in the system of the central mechanisms of biorhythm control

BACKGROUND: This study was undertaken to assess the safety and efficacy of a treatment involving brief counseling and the nicotine patch among hospital inpatients and to identify variables associated with long-term smoking cessation following hospitalization. METHODS: One hundred eighty-five patients were randomly assigned to one of three smoking cessation interventions: (1) A Minimal Care (MC) condition, consisting of a brief physician-delivered motivational message to stop smoking, (2) a Counseling + Active Nicotine Patch (CAP) condition in which patients received the motivational message, a 6-week supply of nicotine patches, and extended bedside and telephone counseling, and (3) a Counseling + Placebo Patch (CPP) condition identical to the CAP condition except the supplied patches contained no nicotine. RESULTS: At 6-month follow-up, abstinence rates for the three treatments were 4.9, 6.5, and 9.7% for the MC, CPP, and CAP treatments, respectively. These differences were not statistically significant. Patients admitted for respiratory disease were more likely to quit than patients with any other diagnosis. The nicotine patch was well tolerated by hospital inpatients. CONCLUSIONS: The initiation of nicotine patch therapy during hospitalization appears to be safe when used among patients carrying a wide range of diagnoses. Our study provided no evidence of the superiority of nicotine patches versus placebo, but this does not preclude the possibility that future research using larger samples might detect differences between patch groups. Hospital interventions for smoking cessation may be most effective among patients hospitalized for a smoking-related illness such as respiratory disease.
