Abstract
The A1 allele of the dopamine D2 receptor gene (DRD2) is associated with a reduced number of dopamine binding sites in the brain and with the increased likelihood of substance abuse and addictive behavior. In a study of smokers enrolled in an open-label, randomized effectiveness trial, we investigated whether variants in the DRD2 receptor gene are associated with smoking cessation outcomes following treatment with a combination of bupropion SR and behavioral counseling. Adherence to treatment and point-prevalent smoking status were assessed at 3 and 12 months, respectively, following a target quit date. Compared to women who carry both A2 alleles, women with at least one A1 allele were more likely to report having stopped taking bupropion due to medication side effects (odds ratio (OR)=1.91, 95% confidence interval (CI)=1.01-3.60; P<0.04) and at 12 months were somewhat more likely to report smoking (OR=0.76, 95% CI=0.56-1.03; P<0.076). Significant associations or trends were not observed in men. In women, individual variability in responsiveness to bupropion-based treatment may be partially due to differences in genetic variants influencing dopamine receptor function.

Abstract
Studies of the influence of social support on successful smoking cessation have been based on the smoker's perceptions only. In this pilot study of 58 couples, pregnant women who had smoked in the 30 days before pregnancy and their partners reported the positive and negative support for cessation they had received (women) or provided (partners). Mean levels of the women's and partners' perceptions of support were compared, and correlations of the two reports were analyzed while controlling for the effect of the couple's smoking status. Women's and partners' reports were similar except partners reported wanting the women to stop smoking more than women perceived. Women's and partners' perceived negative support were moderately correlated (r approximately equal to .48, p approximately equal to .001). Partner-reported positive support also was associated with women's perceived negative support (r approximately equal to .30, p approximately equal to .03). These relationships remained signif cant after controllingfor partners' and women's smoking status. Generally, partners reported giving more positive and less negative support than women perceived. Results suggest the need for further examination of couples' perceptions of support and the impact on smoking cessation during pregnancy.

Abstract
PURPOSE To examine the effect of lifestyle on the effectiveness of a low-intensity dietary intervention. DESIGN A secondary data analysis was performed using data from the Eating Patterns Study, a randomized controlled trial that found that self-help materials with physician advice was effective in changing dietary intake and behavior. SETTING Primary care clinics in a large health maintenance organization. SUBJECTS A total of 2111 patients with a routine scheduled appointment with their primary care physicians. MEASURES Participants were grouped into one of six health lifestyle patterns based on similarities in baseline measures of alcohol intake, smoking, diet quality, and exercise. Within each lifestyle pattern, changes from baseline in usual fat and fiber intake (based on a food frequency) and a fat and fiber behavior score were compared at 3 months and 12 months for intervention vs. control participants. INTERVENTION Self-help materials delivered by a physician with advice to change diet. RESULTS Intervention participants in the fitness lifestyle group made the largest changes relative to controls for each dietary outcome at 3 and 12 months. For intervention participants defined by their alcohol intake or current smoking, either no changes in diet were observed compared with controls, or early changes were not sustained over time. Intervention-control comparisons within the remaining lifestyle patterns showed smaller dietary changes compared with the fitness lifestyle. This finding was similar to previously published results. CONCLUSIONS This randomized controlled trial had limited power to detect subgroup differences; however, these results suggest that lifestyle patterns may be useful in the development of effective, targeted interventions to change behavior.

Abstract
The authors evaluated an expanded measure of intrinsic and extrinsic motivation for smoking cessation in a population-based sample of 897 pregnant smokers (500 current smokers and 397 recent quitters). The measure assessed motivation related to pregnancy and parenthood in addition to general intrinsic and extrinsic dimensions. Current smokers at baseline who quit smoking by 28 weeks of pregnancy (n = 102) had significantly higher baseline levels of pregnancy-related motivation than continuing smokers. Extrinsic and pregnancy motivation dropped between baseline and 28 weeks of pregnancy among continuing smokers. Higher levels of intrinsic relative to extrinsic motivation at baseline were associated with sustained abstinence during the first 2 months postpartum. Results suggest that both general and pregnancy-specific motivation are important for smoking cessation and relapse prevention during pregnancy. Interventions to enhance the salience of health benefits over and above those related to pregnancy and other intrinsic benefits of a greater sense of self-control could protect against postpartum relapse.

Abstract
OBJECTIVE To compare the implementation, delivery, and implications for dissemination of 2 different maternal smoking-cessation/relapse-prevention interventions in managed care environments. STUDY DESIGN Healthy Options for Pregnancy and Parenting (HOPP) was a randomized, controlled efficacy trial of an intervention that bypassed the clinical setting. Stop Tobacco for OuR Kids (STORK) was a quasi-experimental effectiveness study of a point-of-service intervention. Both incorporated prenatal and postnatal components. PATIENTS AND METHODS Subjects in both studies were pregnant women who either smoked currently or had quit recently. The major intervention in HOPP was telephone counseling delivered by trained counselors, whereas the STORK intervention was delivered by providers and staff during prepartum, inpatient postpartum, and well-baby visits. RESULTS In HOPP, 97% of telephone intervention participants reported receiving 1 or more counselor calls. The intervention delayed but did not prevent postpartum relapse to smoking. Problems with intervention delivery related primarily to identification of the target population and acceptance of repeated calls. STORK delivered 1 or more cessation contacts to 91% of prenatal smokers in year 1, but the rate of intervention delivery declined in years 2 and 3. Modest differences were obtained in sustained abstinence between 6 and 12 months postpartum, but not in point prevalence abstinence at 12 months. CONCLUSIONS The projects were compared using 4 of the 5 dimensions of the RE-AIM model including reach, adoption, implementation, and maintenance. It was difficult to apply the fifth dimension, efficacy, because of the differences in study design and purpose of the interventions. The strengths and limitations of each project were identified, and it was concluded that a combined intervention that incorporates elements of both HOPP and STORK would be optimal if it could be implemented at reasonable cost.

Abstract
This paper, delivered as the 2000 Joseph W. Cullen Memorial Award Lecture, reviews smoking cessation treatment research conducted over the past 15 years at the Center for Health Studies, Group Health COOPERATIVE: The research program includes assessment, treatment, and health services research that addressed four main questions: (a) What motivates people to quit smoking? (b) Are self-help interventions effective? (c) Can health care benefits impact the utilization of smoking cessation services? and (d) Does smoking cessation impact health care utilization and costs? In the area of motivation for smoking cessation, an intrinsic-extrinsic model of type of motivation for smoking cessation was used to develop and validate a reasons for quitting scale. Results from administration of the scale across different samples of smokers show that higher levels of intrinsic relative to extrinsic motivation predicts successful cessation. A series of five randomized trials of self-help interventions indicate that self-help interventions accompanied by motivational feedback and/or outreach telephone counseling can be effective. However, the same interventions did not improve long-term abstinence rates in non-volunteer samples of smokers. With regard to health care benefits, we find that full coverage of smoking cessation services improves the reach of proven interventions into the general population of smokers with no significant reductions in effectiveness. Furthermore, studies of smoking cessation and health care utilization find that, although quitters have higher initial costs, their costs go down at the same time that those of continuing smokers' begin to accelerate. Cessation appears to reverse a trajectory of higher health care costs.

Abstract
BACKGROUND Addressing non-alcoholic, at-risk patterns of alcohol consumption that are associated with increased morbidity and mortality is an important health care priority. OBJECTIVE The objective was to describe the prevalence and characteristics of at-risk drinkers in a population-based sample of adults with routine primary care visits. METHODS Three thousand four hundred thirty-nine patients with advance appointments in 23 primary care practices completed a health survey prior to their visit. At-risk drinking was defined as consuming an average of two or more drinks per day (chronic drinking), or two or more occasions of consuming five or more drinks in the past month (binge drinking), or, in the past month, one or more occasion of driving after consuming three or more drinks (drinking and driving). RESULTS Prevalence was: 11% at-risk drinking; 63% light to moderate drinking; 26% abstinence. Abstainers differed from alcohol users on demographics (older, fewer Caucasian, lower income, more unemployed), other health behaviors (less exercise, lower rates of smoking, and marijuana and cocaine use), and family history of alcohol problems (lower). Abstainers also reported poorer physical and psychological health. Compared to light to moderate drinkers, at-risk drinkers were more likely to be male, unmarried, and to use other substances (tobacco, marijuana, and cocaine). Among at-risk drinkers, those with two or more risk factors were more likely male, consumed more alcohol per week, had higher AUDIT scores and were more motivated to change their drinking. Among those with only one risk factor, binge drinkers reported high rates of tobacco and marijuana use, relatively poor perceived health, and the highest proportion of negative consequences from drinking. CONCLUSIONS At least 1 in 10 patients making routine primary care visits have drinking practices that place them at risk for negative consequences from drinking. Three drinking patterns that can be used to define at-risk drinking are relatively distinct.

Abstract
OBJECTIVES Physicians acknowledge the need to advise their patients about dietary habits, but they may not have the training or tools to do this efficiently. In the context of a randomized trial, we investigated the feasibility of enlisting physicians to implement a dietary intervention in the primary care setting. METHODS Physicians from 14 primary care practices were assigned via randomization to introduce a self-help booklet to promote dietary change at routine appointments. Delivery of the booklet was recorded by these intervention physicians at the clinic appointment; intervention participants were asked 3 months later in a telephone interview about whether they received and used the booklet. RESULTS According to physician documentation, 95% of intervention participants who kept an appointment (n = 935) received the booklet; among participants completing a 3-month interview (n = 890), 96% reported the same. However, only about 50% of participants reported receiving the booklet from their physician; the remainder received the booklet from other clinic staff. Overall, 93% reported reading at least part of the booklet. Use of the booklet varied little whether it was delivered by a physician or staff person, but it was more likely to be read as time spent discussing the booklet increased. CONCLUSIONS Physician cooperation and evidence of intervention effectiveness support the use of primary care for the delivery of interventions to change diet; training the entire health team and repeating dietary advice at subsequent visits may improve the success of such interventions.

Abstract
BACKGROUND This study evaluated a tailored, multiple-component self-help intervention designed to promote lower fat and higher fruit and vegetable consumption. METHODS Participants were 1,459 adults selected at random, stratified by sex and age (18-34, 35-54, 55-69), from enrollees of a large health maintenance organization. After completing a baseline telephone survey, participants were randomized to receive the intervention (consisting of a computer-generated personalized letter, a motivational phone call, a self-help manual, a package of supplementary materials, computer-generated behavioral feedback based on a self-administered food frequency questionnaire, and newsletters) or to receive no materials. Evaluation was based on 1,205 (86.5%) participants who completed both a 3- and a 12-month follow up survey. RESULTS The intervention effect +/- SE for fat, based on a diet habits questionnaire, was -0.10 +/- 0.02 (P < 0.001), corresponding to a reduction of approximately 0.8 percentage points of percentage energy from fat. For fruits and vegetables, the intervention effect was 0.47 +/- 0.10 servings/day (P < 0.001). Intervention effects were similar across age and sex groups. CONCLUSIONS Tailored, self-help interventions can effectively promote dietary change among both men and women and among younger as well as older adults.

Abstract
OBJECTIVE Although recent screening guidelines recommend annual fecal occult blood testing (FOBT) for adults aged > or = 50, a number of studies report that these tests are underused. Systematic efforts to increase awareness of colorectal cancer (CRC) and to promote screening participation are needed to meet national objectives for CRC control. METHODS This study examined CRC-screening practices and evaluated factors related to recent participation in screening by FOBT in a sample of women aged 50 to 80 who were surveyed about their use of clinical preventive services at Group Health Cooperative, a managed care organization in western Washington State. RESULTS Of the 931 women eligible for analysis, 75% reported ever having been screened by FOBT and 48% reported having been screened within 2 years before the survey. Participation in screening did not vary by demographic characteristics or by perceived or actual risk of CRC. Women with a positive attitudes toward CRC screening had sevenfold greater odds of recent screening by FOBT (odds ratio=7.1; 95% confidence interval, 4.4 to 11.6). Only 58% of study women reported that their physicians encouraged CRC screening, but this factor was strongly related to participation (odds ratio=12.7; 95% confidence interval, 6.6 to 24.4). CONCLUSIONS We identified several areas in which understanding of CRC risk may be low. As a whole, these findings suggest that effective strategies to control CRC may include efforts to improve knowledge of risk and prevention, but must also appeal directly to primary care physicians to identify and address their barriers to screening recommendations.

Abstract
OBJECTIVES To present results from an outcome evaluation of the Henry J. Kaiser Family Foundation's Community Health Promotion Grants Program (CHPGP) in the West, which represented a major community-based initiative designed to promote improved health by changing community norms, environmental conditions, and individual behavior in 11 western communities. METHODS The evaluation design: 14 randomly assigned intervention and control communities, 4 intervention communities selected on special merit, and 4 matched controls. Data for the outcome evaluation were obtained from surveys, administered every two years at three points in time, of community leaders and representative adults and adolescents, and from specially designed surveys of grocery stores. Outcomes for each of the 11 intervention communities were compared with outcomes in control communities. RESULTS With the exception of two intervention communities-a largely Hispanic community and a Native American reservation-we found little evidence of positive changes in the outcomes targeted by the 11 intervention communities. The programs that demonstrated positive outcomes targeted dietary behavior and adolescent substance abuse. CONCLUSIONS Improvement of health through community-based interventions remains a critical public health challenge. The CHPGP, like other prominent community-based initiatives, generally failed to produce measurable changes in the targeted health outcomes. Efforts should focus on developing theories and methods that can improve the design and evaluation of community-based interventions.

Abstract
Evidence-based guidelines hold considerable promise for continued improvement of health-care delivery. However, the availability of clinical practice guidelines does not automatically lead to changes in practice patterns. Using a "push-pull-capacity" model, this article describes strategies to improve guideline implementation for three types of organizations: national organizations, insurer and health-care organizations, and health-care purchasers. Push strategies focus on the guideline development process and include rigorous review and meta-analysis of peer-reviewed research, and use of multidisciplinary expert teams, subjecting guidelines to peer review and comment and using measurable clinical outcomes to define guidelines. PULL: strategies focus on creating a demand for guideline implementation and include professional organization endorsement, quality measures based on guideline-related outcomes, and guideline-based performance objectives in purchaser contracts and physician compensation agreements. Capacity strategies focus on systems that facilitate guideline implementation. Example strategies are providing benefit coverage and reimbursement for guideline-based treatment protocols, and implementing clinical information systems for population-based tracking, outcomes monitoring, and benchmarking feedback.

Abstract
OBJECTIVES Little is known about what happens when individuals attempt to make multiple behavior changes simultaneously. Pregnant women in particular are often in the position of needing to change several behaviors at once, including giving up more than one pleasurable substance. We investigated the success of pregnant women in spontaneously quitting tobacco, alcohol, or caffeine, alone or in combination. METHODS Pregnant women (n = 7489) were identified in the practices of large health maintenance organizations in Seattle and Minneapolis and were interviewed by telephone. Analyses examined the patterns of using and quitting more than one substance, and the extent to which using more than one substance predicts ability to quit other substances. RESULTS Use of the three substances tended to cluster within individuals. Users of multiple substances were less likely to quit each substance than users of single substances. However, in the subgroup of multiple substance users who had quit one substance, having quit a second substance was more, rather than less, common. In multivariate analyses predicting quitting, demographic variables, and not having been pregnant previously were significant predictors of quitting each substance; being a nonsmoker predicted quitting alcohol, and being a nonsmoker and nondrinker predicted quitting caffeine. CONCLUSIONS The reasons for difficulty in quitting more than one substance are unknown but may include the difficulty of formulating appropriate behavioral strategies or less concern about healthy behavior in pregnancy. Many women in the study successfully quit using two substances, however, and counseling should focus on achieving that outcome.

Abstract
Perceived stress and depressive symptoms were examined as correlates and predictors of smoking cessation during pregnancy in a sample of 819 pregnant smokers (454 baseline smokers and 365 baseline quitters). Women who quit early in pregnancy had lower levels of stress and depressive symptoms than baseline smokers. Adjusting for level of addiction and other demographic factors related to stress and depressive symptoms eliminated the significant association between depressive symptoms and smoking cessation. Lower levels of stress and depressive symptoms were not predictive of cessation in later pregnancy. Prenatal healthcare providers should continue to assess level of addiction and provide targeted intensive cessation interventions. Interventions that reduce stress and depression may also be of benefit to women who are continuing smokers in early pregnancy.

Abstract
To increase mammography participation, the authors implemented an outreach intervention translating concepts from expectancy value theory into a motivational interviewing telephone intervention that included the opportunity to schedule a screening appointment. Process data are presented from 491 women who had not scheduled a mammogram within 2 months of receiving a mailed invitation from a managed care organization's centralized breast cancer screening program. A total of 83% of targeted women accepted the counseling calls. Counselors rated 84% of completed calls as either receptive or neutral in tone. Women with prior mammography experience were more likely to be receptive and to schedule a screening appointment during the calls than were women with no prior experience. Topics discussed during the calls also differed between women with and without prior mammography experience. Implications for dissemination of counseling interventions in health care organizations are discussed.

Abstract
OBJECTIVE This study was undertaken to evaluate a smoking cessation intervention provided to women smokers as follow-up to cervical cancer screening. METHODS Women who had had a Pap test in the prior month (N = 4,053) were called to complete a survey that assessed smoking status; 580 identified smokers were randomized to receive Usual care (n = 292) or a Self-help intervention (n = 288) that included a self-help booklet, a smoking and reproductive health information card, and three telephone counseling calls. Women were followed up at 6 and 15 months post-base line. RESULTS Cessation rates in the Usual care (UC) and Self-help (SH) groups did not differ at the 6-month (UC 10.5% vs SH 10.9%, P = 0.56) or 15-month follow-up (UC 15.5% vs SH 10.6%, P = 0.17). Among women with an abnormal Pap test result there were no differences by study group in cessation rates at 6-month (UC 9.8% vs SH 11.0%, P = 0.71) or 15-month follow-up (UC 14.6% vs SH 13.4%, P = 0.96). CONCLUSION Integrating interventions into the clinical setting and involving providers at the point of care may have greater potential for capitalizing on this "teachable moment."

Abstract
OBJECTIVE To assess female primary care patients' knowledge about breast cancer genetics and attitudes toward genetic testing. DESIGN Self-administered survey. PARTICIPANTS A convenience sample of 91 female patients awaiting appointments at a large primary care clinic of Group Health Cooperative in Seattle, Washington. RESULTS Forty-seven percent of women had read or heard almost nothing about genetic susceptibility testing, and most did not know the answers to questions that assessed knowledge about breast cancer genetics. Eighty-one percent "somewhat" or "strongly" agreed that testing should be offered to everyone; women who had heard or read about genetic testing for breast cancer were more likely to agree that genetic testing should be offered only to people who have a reason to think that they have an altered gene. When asked whether they planned to have genetic testing for breast cancer, many women said "probably or definitely yes" (71% would do so if insurance covered the cost; 44% would do so even if they had to pay out-of-pocket). CONCLUSIONS Although most women knew little about genetic testing, many expressed interest in being tested and believed that it should be offered to everyone. Primary care providers may be asked to educate women about cancer genetics and appropriate use of susceptibility testing.

Abstract
OBJECTIVE To increase our understanding of the factors that impede or promote counseling about hormone replacement therapy, we asked clinicians to provide information concerning barriers and strategies to promote counseling. DESIGN We asked clinicians to consider two different scenarios: (1) what they do in they current practice and (2) what they would do if their health care systems implemented the United States Preventive Services Task Force recommendation regarding hormone replacement therapy counseling. A total of 49 of 50 invited clinicians participated in one of six focus group interviews (three women's groups and three men's groups). Our analysis consisted of four steps: (1) identifying segments and classifying them into themes, (2) categorizing themes into topic areas, (3) establishing a final consensus of themes and topics, and (4) ascertaining similarities and contrasts among groups. Transcripts of sessions were analyzed across groups for themes using a text-based analysis system. Conceptualization of themes was derived using a system model of preventive care. Interrater agreement before consensus was good: Kappa (kappa) ranged from 0.70 to 1.00. RESULTS For current practice, identified barriers included lack of information about risks and benefits, unique challenges of counseling, and lack of resources to conduct counseling. The major strategies suggested were to develop and distribute patient education materials. Discussions about barriers to implementing the United States Task Force recommendation focused on lack of information and resources. CONCLUSIONS Suggested strategies were multiple, involving individual-, relationship-, and system-level interventions. We expect the strategies identified to be supportive of future efforts to promote counseling for hormone replacement therapy.

Abstract
OBJECTIVES This study is an evaluation of relapse prevention interventions for smokers who quit during pregnancy. METHODS Pregnant smokers at 2 managed care organizations were randomized to receive a self-help booklet only, prepartum relapse prevention, or prepartum and postpartum relapse prevention. Follow-up surveys were conducted at 28 weeks of pregnancy and at 8 weeks, 6 months, and 12 months postpartum. RESULTS The pre/post intervention delayed but did not prevent postpartum relapse to smoking. Prevalent abstinence was significantly greater for the pre/post intervention group than for the other groups at 8 weeks (booklet group, 30%; prepartum group, 35%; pre/post group, 39%; P = .02 [different superscripts denote differences at P < .05]) and at 6 months (booklet group, 26%, prepartum group, 24%; pre/post group, 33%; P = .04) postpartum. A nonsignificant reduction in relapse among the pre/post group contributed to differences in prevalent abstinence. There was no difference between the groups in prevalent abstinence at 12 months postpartum. CONCLUSIONS Relapse prevention interventions may need to be increased in duration and potency to prevent post-partum relapse.

Abstract
BACKGROUND Lack of information about the effect of insurance coverage on the demand for and use of smoking-cessation services has prevented widescale adoption of coverage for such services. METHODS In a longitudinal, natural experiment, we compared the use and cost effectiveness of three forms of coverage with those of a standard form of coverage for smoking-cessation services that included a behavioral program and nicotine-replacement therapy. The study involved seven employers and a total of 90,005 adult enrollees. The standard plan offered 50 percent coverage of the behavioral program and full coverage of nicotine-replacement therapy. The other plans offered 50 percent coverage of both the behavioral program and nicotine-replacement therapy (reduced coverage), full coverage of the behavioral program and 50 percent coverage of nicotine-replacement therapy (flipped coverage), or full coverage of both the behavioral program and nicotine-replacement therapy. RESULTS Estimated annual rates of use of smoking-cessation services ranged from 2.4 percent (among smokers with reduced coverage) to 10 percent (among those with full coverage). Smoking-cessation rates ranged from 28 percent (among users with full coverage) to 38 percent (among those with standard coverage). The estimated percentage of all smokers who would quit smoking per year as a result of using the services ranged from 0.7 percent (with reduced coverage) to 2.8 percent (with full coverage). The average cost to the health plan per user who quit smoking ranged from $797 (with standard coverage) to $1,171 (with full coverage). The annual cost per smoker ranged from $6 (with reduced coverage) to $33 (with full coverage). The annual cost per enrollee ranged from $0.89 (with reduced coverage) to $4.92 (with full coverage). CONCLUSIONS Use of smoking-cessation services varies according to the extent of coverage, with the highest rates of use among smokers with full coverage. Although the rate of smoking cessation among the benefit users with full coverage was lower than the rates among users with plans requiring copayments, the effect on the overall prevalence of smoking was greater with full coverage than with the cost-sharing plans.

Abstract
OBJECTIVES Use of health services by children of smokers and nonsmokers was compared to assess whether exposure to environmental tobacco smoke resulted in greater use of health services among children of smokers. METHODS Primary care and emergency room visits, asthma-related prescriptions, and inpatient stays over the 42-month study period were compared for children of smokers (n = 498) and nonsmokers (n = 1062) who were enrolled in a health maintenance organization. Parents of children aged 1 through 11 years were identified from participants in 2 randomized smoking cessation trials. RESULTS After adjustment for parental age, education, and health status and for child's age, there were no differences between children of smokers and children of nonsmokers in use of primary care or emergency room visits, asthma-related prescriptions, or inpatient stays. However, among those with any preventive care visits, children of smokers had significantly fewer visits than children of nonsmokers. CONCLUSIONS Further study is needed to elucidate whether parents who smoke underutilize health services for their children or use services differently from nonsmoking parents and whether these differences have cost implications.

Abstract
OBJECTIVE To determine whether 1) women smokers are aware that smoking increases their risk for cervical cancer; 2) awareness of risk factors and its impact on motivation to quit smoking vary by age; and 3) providers are advising smokers to quit smoking during routine gynecologic visits. METHODS Women aged 18 years and older who had a Papanicolaou test in the prior month were identified from a managed care cytology database. Four weeks after receiving their test result, women were called to complete a health behavior survey in which their smoking status, sexual history, knowledge of risk factors for cervical cancer, and motivation to quit smoking were assessed. RESULTS Only 49% of the 613 smokers surveyed were aware that smoking increased their risk of cervical cancer. Women aged 34 years and younger were significantly more likely to agree that smoking increased their risk for cervical cancer than women aged 45 years or older (54% versus 40%). Concern that smoking might cause cervical cancer or other cancers was endorsed highly by women as a motivator for cessation, particularly for women smokers aged 18-26 (mean 8.1 and 7.6 on 10-point scales, respectively). About 50% of the women reported that their provider had asked about smoking and had encouraged cessation. Only about 30% of smokers were aware of well-established risk factors for cervical cancer such as the number of lifetime sexual partners and not using a condom. CONCLUSION Routine gynecologic screening visits represent an important and underutilized clinical opportunity to intervene with young women smokers.

Abstract
Perceptions of support for cessation of smoking during pregnancy, likelihood of quitting, and partner smoking status were explored in a sample of 688 pregnant smokers (372 baseline smokers and 316 baseline quitters). Women with nonsmoking partners were significantly more likely to be baseline quitters than women with partners who smoked. Baseline quitters reported significantly more positive support from their partners than did continuing smokers (p = .02). Neither partner smoking status nor partner support at baseline was associated with cessation or relapse later in pregnancy. Women reported greater support, both positive and negative, from nonsmoking partners than from partners who smoked (p = .001). Among partner smokers, those who were trying to quit were perceived to be particularly supportive. Cessation interventions for expectant fathers may increase pregnant women's success at quitting.

Abstract
OBJECTIVES This study examined whether pregnancy intention was associated with cigarette smoking, alcohol drinking, use of vitamins, and consumption of caffeinated drinks prior to pregnancy and in early pregnancy. METHODS Data from a telephone survey of 7174 pregnant women were analyzed. RESULTS In comparison with women whose pregnancies were intended, women with unintended pregnancies were more likely to report cigarette smoking and less likely to report daily vitamin use. Women with unintended pregnancies were also less likely to decrease consumption of caffeinated beverages or increase daily vitamin use. CONCLUSIONS Pregnancy intention was associated with health behaviors, prior to pregnancy and in early pregnancy, that may influence pregnancy course and birth outcomes.

Abstract
In chronic illness, day-to-day care responsibilities fall most heavily on patients and their families. Effective collaborative relationships with health care providers can help patients and families better handle self-care tasks. Collaborative management is care that strengthens and supports self-care in chronic illness while assuring that effective medical, preventive, and health maintenance interventions take place. In this paper, the following essential elements of collaborative management developed in light of behavioral principles and empirical evidence about effective care in chronic illness are discussed: 1) collaborative definition of problems, in which patient-defined problems are identified along with medical problems diagnosed by physicians; 2) targeting, goal setting, and planning, in which patients and providers focus on a specific problem, set realistic objectives, and develop an action plan for attaining those objectives in the context of patient preferences and readiness; 3) creation of a continuum of self-management training and support services, in which patients have access to services that teach skills needed to carry out medical regimens, guide health behavior changes, and provide emotional support; and 4) active and sustained follow-up, in which patients are contacted at specified intervals to monitor health status, identify potential complications, and check and reinforce progress in implementing the care plan. These elements make up a common core of services for chronic illness care that need not be reinvented for each disease.

Abstract
An intrinsic-extrinsic model of motivation for smoking cessation is extended to a population-based sample of smokers (N = 1,137), using a previously validated Reasons for Quitting (RFQ) scale. Psychometric evaluation of the RFQ replicated the model that includes health concerns and self-control as intrinsic motivation dimensions and immediate reinforcement and social influence as extrinsic motivation dimensions. Compared to volunteers, the population-based sample of smokers reported equivalent health concerns, lower self-control, and higher social influence motivation for cessation. Within the population-based sample, women compared to men were less motivated to quit by health concerns and more motivated by immediate reinforcement; smokers above age 55 expressed lower health concerns and higher self-control motivation than smokers below age 55. Higher baseline levels of intrinsic relative to extrinsic motivation were associated with more advanced stages of readiness to quit smoking and successful smoking cessation at a 12-month follow-up. Among continuing smokers, improvement in stage of readiness to quit over time was associated with significant increases in health concerns and self-control motivation.

Abstract
This study reports the validity, reliability, and responsiveness of a 33-item fat- and fiber-related behavior questionnaire (FFB) and describes how this instrument provides insight into the process of adopting healthy diets. Data are from the Eating Patterns Study, a randomized clinical trial of a physician-delivered, self-help intervention to reduce fat and increase fiber intake. Intervention (n = 850) and control participants (n = 945) completed both a food frequency questionnaire and the FFB at baseline and at 3 and 12 months postintervention. Validity, as assessed by correlation of the FFB with the food frequency questionnaire at baseline, was 0.53 for fat (fat scale with percentage energy from fat) and 0.50 for fiber (fiber scale with fiber g/1000 kcal; both P < 0.001). Reliability, as assessed by the intraclass correlation in controls across all three time points, was 0.77 for the fat scale and 0.74 for the fiber scale (both P < 0.001). The largest changes in fat-related behavior were in avoiding fat as a flavoring and in using specially manufactured low-fat foods, and the largest changes in fiber-related behavior were in substituting high-fiber versions of common foods. Overall, the FFB was a reasonably valid and reliable measure of dietary intake, which provided insight into the behavioral effects of the dietary intervention.

Abstract
OBJECTIVES This study evaluated the effectiveness of a low-intensity dietary intervention in primary care practice in lowering dietary fat intake and raising dietary fiber intake. METHODS A randomized controlled trial of 28 physician practices in six primary care clinics enrolled, by telephone, adult patients who had appointments for nonurgent nonacute visits. Of 3490 eligible patients contacted, 2111 completed baseline interview; 86.1% also completed a 12-month follow-up. Physicians gave intervention participants a self-help booklet and a brief motivational message. Changes in fat and fiber from baseline to 12-month follow-up were evaluated. RESULTS Intervention and control groups both reported a decrease in fat intake and an increase in fiber intake. The differential change and 95% confidence interval (CI) for the percentage of energy obtained from fat was -1.2 (CI = -0.71, -1.7) (P = .0015), for grams fiber/1000 kcal 0.32 (CI = -0.066, 0.71) (P = .086), for fat score -0.044 (CI = -0.016, -0.072) (P = .010), and for fiber score 0.036 (CI = 0.011, 0.061) (P = .014), with greater reductions in fat and greater increase in fiber in the intervention group. CONCLUSIONS This low-intensity intervention was effective in dietary behavior change.

Abstract
The incremental effects of (a) a self-help booklet alone, (b) self-help booklet with computer-generated personalized feedback, and (c) self-help booklet, personalized feedback, and outreach telephone counseling were evaluated in a population-based, nonvolunteer sample of smokers. Smokers (N = 1,137) were identified through a telephone survey of a random sample of 5,903 enrollees in a health maintenance organization and randomized to a no-treatment control group or 1 of the 3 intervention conditions. Smoking status was ascertained 3, 12, and 21 months postrandomization. Cotinine validation of self-reported cessation was obtained at the 12-month follow-up. Overall, the telephone counseling significantly increased smoking cessation at the 3-month follow-up, but not at 12 or 21 months. Among smokers who were precontemplative at baseline, telephone counseling significantly increased prevalent abstinence at 3 and 12 months and continuous abstinence at 21 months (defined as self-reported abstinence at 3, 12, and 21 months).

Abstract
Adult men and women (N = 8,748) were given blood cholesterol tests and completed a measure of fat intake and a staging questionnaire that assessed readiness to adopt a cholesterol-lowering diet. Eligibility for the trial was based on plasma cholesterol levels and self-reported dietary intake. Of 772 eligible participants, 545 (70.6%) agreed to join. In multivariate analyses, joiners did not differ from nonjoiners by age, total cholesterol levels, or self-reported dietary fat intake. Women were more likely than men to join the study. Individuals in the preparation stage (defined on the basis of a staging algorithm derived from the transtheoretical model of change) were more likely to join the trial than were precontemplators. An understanding of the determinants of participation in a dietary intervention may be important in the enhancement of high-risk individuals' acceptance of recommendations to make dietary changes.

Abstract
OBJECTIVES To examine how transdermal nicotine is prescribed and used in the general population, and to identify variables associated with successful smoking cessation in patch users. DESIGN Retrospective cohort survey. SETTING A random sample of 70 pharmacies in King County, Washington, were asked to participate. Of those, 33 pharmacies ran computer searches of prescriptions for any nicotine patch dispensed between July 1 and December 31, 1992. A total of 1,087 individuals receiving patches were identified. PATIENTS At least eight months after the nicotine patches were purchased, 972 subjects received questionnaires by mail from the participating pharmacies. The survey was completed by 433 (45.2%) subjects. MAIN RESULTS Eighty percent of the respondents requested patches from a provider, 81% of whom were primary care physicians. Ninety-six percent used the patch, 45% smoked while using the patch, and 37% reported having quit smoking. Smoking cessation was associated with daily patch application (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.2-2.2), abstinence during patch use (OR 7.7, 95% CI 4.8-12.5), and a longer duration of patch use (p = 0.001). A score reflecting counseling intensity by the provider was associated with abstinence while using patches and smoking cessation (chi 2 for tread = 0.01 and 0.04, respectively). CONCLUSIONS Most nicotine patch users request treatment from a primary care physician, suggesting motivation to quit. Almost half continue to smoke while using the patch, a behavior that appears related to a lower level of counseling and an inability to quit. Increasing counseling may positively impact nicotine-patch-assisted smoking cessation in the general population.

Abstract
BACKGROUND The magnitude and timing of the impact of effects of smoking cessation on inpatient and outpatient health care use are uncertain. METHODS Comparison of the use of outpatient and hospital services over time of 2440 persistent smokers and 244 biochemically verified quitters, all of whom were participants in two independent randomized trials of smoking cessation interventions. RESULTS Continued smokers in both trials experienced a 7% to 15% increase in outpatient visits and a 30% to 45% increase in hospital admissions over 5 to 6 years of follow-up. The positive slopes approached or reached statistical significance for all use variables in both trial populations. Among quitters, all health care use rates significantly increased during the year in which they quit; after that, the rates declined progressively. By the fourth year after quitting, all use rates among quitters were lower than those for smokers. The increase in hospitalizations during the year of quitting was more often a cause rather than a consequence of successful smoking cessation. CONCLUSION Successful smoking cessation appears to halt the progressive increase in the use of health services associated with continued smoking within a 4-year period.

Abstract
Adolescent bonding--attachment to, commitment to, and involvement in conventional social activities-decreases the likelihood of engaging in some risk-taking behaviors. The extent to which bonding opportunities in the school environment affect individual's bonding and risk-taking behaviors is less explored. This study tested a model that includes individual and environmental indicators of bonding to predict cigarette smoking, drinking, drug use, and sexual activity among ninth grade students. Survey data representing students in 20 schools in seven western states are reported. Twelfth grade students' bonding and other demographic variables aggregated by school served as environmental indicators of bonding opportunities to predict ninth grade students' bonding and risk-taking behavior. Path analyses indicate the school environment has a direct influence on ninth grade students' bonding and, in turn, on the likelihood they will engage in risky behavior. Implications of these findings for future research directions and intervention design are discussed.

Abstract
OBJECTIVE To describe internists' involvement in primary and secondary prevention of alcohol-related problems, and to evaluate relationships between preventive practices and training, attitudes, and work patterns. DESIGN Cross-sectional survey. PARTICIPANTS A random sample of 152 board-certified internists, < or = 65 years old, who practiced primary care in the continental United States, was selected from the American Medical Association's master list. Ten were ineligible; 99 (70%) of the remaining 142 internists completed questionnaires. MAIN OUTCOME MEASURES The authors evaluated the internists' preventive practices, including the frequency with which they assessed patients' alcohol consumption and advised patients about safe levels of alcohol consumption. The authors also evaluated the internists' opinions about safe levels of alcohol consumption, training and attitudes regarding advising patients about safe levels of consumption, and work patterns. RESULTS Ninety-four percent of the respondents believed they had a responsibility to advise all patients about safe levels of alcohol consumption (primary prevention), though only 30% often/always did so. Eighty percent often/always advised patients who drank three or more drinks daily about safe levels of alcohol consumption (secondary prevention), but many (45%) did not routinely ask patients how much they drank daily. Preventive practices correlated positively with the number of hours/week internists practiced primary care, and with their belief in the effectiveness of preventive advice about alcohol consumption. CONCLUSIONS Internists believe they have a responsibility for primary prevention of alcohol-related problems, but only a minority actively practice it. In contrast, many internists practice secondary prevention, offering advice about safe alcohol consumption to patients who drink three or more drinks daily. The effectiveness of such secondary prevention is limited, however, by incomplete screening regarding level of alcohol consumption.

Abstract
Brief supportive telephone counseling is a promising adjunct to self-help smoking cessation programs. This article reports rates of participation, predictors of participation, and content of telephone counseling calls with nonvolunteer smokers who were identified through health surveys administered to a random sample of enrollees in a health maintenance organization. Eighty-six percent of smokers accepted at least one of three counselor calls; 66% accepted all three calls. Baseline characteristics associated with acceptance of calls included being female and greater average length of time to the first cigarette of the day. Acceptance did not differ significantly by stage of cessation. First calls with smokers who accepted all three calls were longer and were more likely to be with smokers who were willing to take a specific next action step. Overall, 12% of the sample reported having quit smoking by the third counseling call, with the highest quit rate (23%) among smokers who, at baseline, were planning to quit in the next month. Implications for large-scale interventions with smokers in health care and other organizations are discussed.

Abstract
Self-help interventions for smoking cessation are an important bridge between the clinical and public health approaches to smoking cessation. The current literature on self-help interventions is encouraging but incomplete. Although their quit rates are lower than those of more intensive programs, self-help interventions could have a large public health impact because of their potential for widespread distribution. Studies comparing self-help to more intensive treatment suggest that long-term cessation rates for self-help programs are potentially as high as rates for face-to-face interventions, with lower quit rates for self-help programs that are likely due to differences in program adherence. Tailored materials and personalized adjuncts (e.g., written feedback or telephone counseling) that promote program adherence may increase cessation rates.

Abstract
Despite an upward trend in mammography screening rates, rates among some demographic subgroups and rates of annual mammography remain low. Behavioral-based interventions which move beyond invitational strategies to help women overcome their personal barriers may be necessary to increase participation. We developed a heuristic model based on the Health Belief Model and Social Learning Theory with the central hypothesis that the relative importance of environmental barriers in predicting screening behavior is a function of the woman's perceived risk, preventive orientation, and/or concerns about mammography. We completed telephone interviews with 313 women who did not obtain a mammogram and 350 women who had a mammogram within 365 days of an invitation from a Health Maintenance Organization-based breast cancer screening program. Results of multivariate analyses indicated that perceived risk did not mitigate the influence of logistic inconveniences associated with obtaining a mammogram. Preventive orientation as measured by smoking status interacted with belief that symptoms are a necessary prerequisite to a mammogram as a powerful predictor of participation; the greatest negative impact of concerns on participation was found among smokers. A similar relationship between concerns and participation, although only marginally significant, was observed among those who perceived it to be difficult to get to the screening center. Implications of the results for development of behavioral interventions and additional research are discussed.

Abstract
BACKGROUND Although rates of mammography screening among women in the general population have been increasing they still fall short of national goals. This study evaluated the effects on rates of participation in mammography screening of obtaining risk factor information and providing general or personalized risk information through direct mailed correspondence. METHODS Women enrollees in a health maintenance organization (N = 2,076), age 50 and above, were randomized to one of the following four groups: (a) no risk factor questionnaire + generic invitation, (b) no risk factor questionnaire + general risk invitation, (c) risk factor questionnaire + general risk invitation, and (d) risk factor questionnaire + personal risk invitation. Computerized visit records were monitored for 12 months following a mailed invitation to assess whether a mammogram had been obtained. RESULTS Overall participation was 37.5% and the rate of participation did not differ significantly across groups (P = 0.26). Participation was related to age (P < 0.02), with rates highest for women ages 60-69 years (42.7%) compared with those for women ages 50-59 (35.5%) and those age 70+ (33.7%). Among women with a family history of breast cancer, the personalized risk invitation was associated with significantly higher participation compared with general risk invitation (66.7 versus 42.9%, respectively; P < 0.003). CONCLUSIONS Women with a family history of breast cancer are more likely to obtain a mammogram if that fact is reinforced as a risk factor. Research on environmental barriers to mammography screening may suggest alternative strategies for increasing participation.

Abstract
A basic premise of community-based health promotion is that enduring changes in health behaviors are facilitated by changing community norms or the standards of acceptable behavior in the community. We examine whether community-level influences on individuals' normative attitudes can be related to cigarette smoking, alcohol consumption, and dietary fat intake. We conducted a random-digit dialing survey of 8,849 adults in 15 communities in the western United States as part of the evaluation of the Henry J. Kaiser Family Foundation Community Health Promotion Grant Program. We found independent associations among attitudes for tobacco, alcohol, and diet and both individual-level and community-level characteristics. A significant community effect on attitudes remained even when we controlled for individual demographics and health behaviors, as well as for the overall prevalence of the target health behavior in the community. The specific community characteristics that account for this effect were not clear in our analyses, suggesting that influential characteristics vary from community to community.

Abstract
A substantial proportion of women who quit smoking during pregnancy will relapse in postpartum. In order to better understand the psychosocial factors which precipitate relapse to smoking we conducted a prospective study of postpartum smoking relapse among a cohort (N = 106) of women who quit smoking during pregnancy. Participants were surveyed by telephone after the 28th week of pregnancy, and at 6 weeks and 6 months postpartum. Point prevalence estimates of smoking relapse indicated that at 6 weeks and 6 months follow-up, 24% (n = 26) and 40% (n = 42), respectively, of the women had returned to regular smoking. Spouse's smoking status, social support, decreases in self-efficacy, and the types of coping strategies used to resist smoking in pregnancy and postpartum predicted relapse to smoking in postpartum. Longitudinal data indicated that relapse occurred relatively gradually suggesting that early postpartum is not too late to encourage new mothers to remain abstinent.

Abstract
To assess the applicability of Prochaska and DiClemente's stage model to dietary change, stage of dietary fat reduction was assessed in two samples of adults. Results were consistent across the two samples. Males and females differed in their distribution across five stages of change, with more males than females in a precontemplation stage and more females than males in a maintenance stage. Significant positive correlates with stage for men and women were age, education, body mass index, number of chronic conditions and being told one has a high serum cholesterol. For both genders, stage of dietary fat reduction was significantly associated with percent of calories from fat, even when controlling for demographic and health status covariates.
