Efficacy and cost-effectiveness of a clinic-based counseling intervention tested in an ethnically diverse sample of pregnant smokers.

OBJECTIVE: Rates of cigarette smoking are higher among women who receive obstetric care through publicly funded prenatal clinics. This study compared smoking outcomes for pregnant women (n=105) who were randomized to receive either usual care (standard cessation advice from the health care provider) or an intervention conducted in the prenatal clinic consisting of 1.5 h of counseling plus telephone follow-up delivered by a masters prepared mental health counselor. METHODS: Subjects were 105 low income, predominantly Hispanic, pregnant patients in an urban prenatal clinic. Smoking outcomes were assessed at end of pregnancy and 6 months post-partum. RESULTS: At follow-up, 28.3% and 9.4% of participants in the experimental intervention and 9.6% and 3.8% of patients in usual care were abstinent at end of pregnancy (p=.015) and 6 months post-partum, respectively (p=.251). Cost of the intervention was $56 per patient and cost to produce a non-smoker at end of pregnancy was $299. CONCLUSIONS: This model for intervention was cost-effective and was associated with significantly lower smoking rates at end of pregnancy. PRACTICAL IMPLICATIONS: If these findings are replicated, prenatal clinics could offer the option for intensive smoking cessation treatment by training mental health counselors to deliver one extended smoking cessation counseling session.

Changes in readiness to quit and self-efficacy among adolescents receiving a brief office intervention for smoking cessation.

PURPOSE: To examine changes in readiness to quit and self-efficacy among adolescents who received a clinic-based, brief office intervention (BOI) for smoking cessation. METHODS: This study utilized a prospective, pre-post- treatment design. Participants were adolescent smokers (34 females, 35 males) with a mean +/- SD age of 15.8 +/- 1.4 years; 86% were Caucasian, who were randomly assigned to receive the BOI as part of a larger clinical trial. They were recruited from three cities in the Midwest and Northeastern part of the United States. After the baseline assessment, the BOI was designed for adolescents to receive four weekly individual sessions with a research counselor lasting between 10 and 40 min each. The BOI includes motivational interviewing and cognitive-behavioral techniques. Readiness to quit was assessed at each treatment session using the stages of change algorithm. The validated Adolescent Smoking Self-Efficacy Scale (SES) was used to assess self-efficacy at baseline (week 0) prior to the intervention and at post-treatment (week 4). The SES items comprise three factors or subscales: opportunities to smoke, emotional stress, and friends' influence. RESULTS: The percentage of adolescents who made improvement on readiness to quit from the baseline treatment session was statistically significant (p < .001) for each of the three subsequent treatment sessions. Self-efficacy scores increased significantly (p < .004) from baseline to post-treatment for all three subscales. CONCLUSIONS: Adolescents receiving a BOI progressed in their readiness and self-efficacy to quit. Understanding the change process among adolescent smokers during treatment could influence the design of future stop smoking interventions.

Ethnic variation in socioenvironmental factors that influence adolescent smoking.

PURPOSE: To compare black, Hispanic and white adolescent smokers on socioenvironmental factors associated with smoking. METHODS: The study uses a cross-sectional design. A needs assessment of 1305 current, former and never adolescent smokers from four ethnically and geographically diverse sites in the United States was conducted in 1999. Two sites were selected because they represented urban cities in the Northeast and Midwest with a high proportion of black and Hispanic residents. Two additional sites were selected to recruit rural and suburban adolescents. From this larger sample, 181 subjects from three focal ethnic groups (white n = 138; black n = 24; Hispanic n = 19) who had smoked at least 100 cigarettes in their lifetime and were current smokers (smoked in the past 30 days) were included. The three ethnic groups were compared on the following variables of interest: peer and family influences on smoking, situational factors associated with smoking, places that were likely sites for smoking and perceptions of friends and family as potential support persons for quitting smoking. All data were analyzed with Chi-square analysis. RESULTS: Almost all (96%) of the black adolescents lived with another smoker compared to 68% of Hispanic and 60% of whites (p = .004). Black teens were more likely to smoke with family members (50%) than Hispanics (5%) or whites (25%) (p = .003). In addition, 50% of black teens compared to 5% of Hispanics and 12% of white teens, reported smoking to fit in (p < .0001). Black teens in this study emphasized the familial and social pressures of smoking. Higher rates of acceptance of smoking by family members, role modeling by household members, more prevalent beliefs that smoking is a way to achieve belonging, and lack of perceived support for quitting by friends appear to influence cigarette smoking more for black than white or Hispanic youth. CONCLUSIONS: These preliminary results indicate that familial and household norms play a critical role in influencing cigarette smoking among black teens.
