Relapse and maintenance issues for smoking cessation.

This article reviews short-term (6 months) and longer term (12-24 months) maintenance of cessation and relapse in adult smokers and the factors and treatments that affect these outcomes. MedLine and PsycLIT searches were done for research published in English between 1988 and 1998 meeting a defined set of criteria. Intensive intervention, telephone counseling, and use of pharmacotherapy were found to improve outcomes; however, compared with public health approaches, they reach relatively few smokers. Brief interventions during medical visits are cost-effective and could potentially reach most smokers but are not consistently delivered. Predictors of relapse include slips, younger age, nicotine dependence, low self-efficacy, weight concerns, and previous quit attempts. Potential areas for research, recommendations for longer follow-up assessments, and standard definitions for slip, relapse, and long-term maintenance are discussed.

Analysis of longitudinal substance use outcomes using ordinal random-effects regression models.

In this paper we describe analysis of longitudinal substance use outcomes using random-effects regression models (RRM). Some of the advantages of this approach is that these models allow for incomplete data across time, time-invariant and time-varying covariates, and can estimate individual change across time. Because substance use outcomes are often measured in terms of dichotomous or ordinal categories, our presentation focuses on categorical versions of RRM. Specifically, we present and describe an ordinal RRM that includes the possibility that covariate effects vary across the cutpoints of the ordinal outcome. This latter feature is particularly useful because a treatment can have varying effects on full versus partial abstinence, for example. Data from a smoking cessation study are used to illustrate application of this model for analysis of longitudinal substance use data.

Application of random-effects regression models in relapse research.

This article describes and illustrates use of random-effects regression models (RRM) in relapse research. RRM are useful in longitudinal analysis of relapse data since they allow for the presence of missing data, time-varying or invariant covariates, and subjects measured at different timepoints. Thus, RRM can deal with "unbalanced" longitudinal relapse data, where a sample of subjects are not all measured at each and every timepoint. Also, recent work has extended RRM to handle dichotomous and ordinal outcomes, which are common in relapse research. Two examples are presented from a smoking cessation study to illustrate analysis using RRM. The first illustrates use of a random-effects ordinal logistic regression model, examining longitudinal changes in smoking status, treating status as an ordinal outcome. The second example focuses on changes in motivation scores prior to and following a first relapse to smoking. This latter example illustrates how RRM can be used to examine predictors and consequences of relapse, where relapse can occur at any study timepoint.

A cognitive-behavioral program to improve geriatric rehabilitation outcome.

A program of cognitive-behavioral interventions was applied on a hospital geriatric rehabilitation unit. Unique features were the tailoring of the program to the population and each participant, and the immediate application of the program with distressed patients in a proactive manner designed to maximize rehabilitation outcome. The program was successful in that initially distressed participants achieved rehabilitation goals to the same extent as the nondistressed comparison group, and participant scores on measures of distress and coping, except for anxiety, matched those of comparison patients at discharge.

Effects of social support and relapse prevention training as adjuncts to a televised smoking-cessation intervention.

Smokers registering for a televised cessation program who also expressed interest in joining a support group and who had a nonsmoking buddy were randomly assigned to 3 conditions: no-contact control, discussion, and social support. All Ss received a self-help manual and were encouraged to watch the daily TV program. Ss in the discussion and social support conditions were scheduled to attend 3 group meetings (one with a buddy). Social support Ss and buddies received training in support and relapse prevention. A 4th analysis group was composed of Ss who failed to attend any of the scheduled meetings (no shows). There were strong group effects at the end of treatment. Abstinence rates were highest in the social support group, followed, in order, by the discussion group, no shows, and no-contact controls. The social support group improved outcome by increasing both the level of support and program material use (reading the manual and watching TV).

Cigarette smoking under stress: the role of coping expectancies among smokers in a clinic-based smoking cessation program.

This study examined 2 expectancies to explain smoking under stress: smokers' expectations about their ability to cope with stress while remaining abstinent and their expectations about the stress-ameliorating and coping benefits of smoking under stress. The interaction of the expectancies concurrently predicted smoking urge under stress, which, in turn, predicted subsequent smoking. The interaction of posttreatment expectancies prospectively predicted smoking status 3 months after treatment, although the coping benefits of smoking expectancy effect was reversed. Expectations about coping ability increased and expectations about the coping benefits of smoking decreased as a function of participating in a smoking cessation program. The discrepant concurrent and prospective findings, reasons that coping expectancies are associated with smoking under stress, and treatment implications are discussed.

Changing knowledge and attitudes about skin cancer risk factors in adolescents.

We examined knowledge, attitudes, and behaviors related to skin cancer, sun exposure, sunscreen use, and use of tanning booths in 903 female and 800 male adolescents. The effectiveness of a brief, school-based intervention designed to increase teens' knowledge and preventive attitudes about skin cancer was also evaluated. Females, older students, and those with high-risk skin types were most likely to use sunscreen and to take precautions. However, overall level of protection was low. Intentions to take precautions were associated with levels of perceived susceptibility to skin cancer, attitudes about the benefits of sun exposure, skin type, and sex. Beyond intentions, sunscreen use was associated with perceived susceptibility and skin type. The one-session, school-based intervention significantly increased knowledge and perceived susceptibility to skin cancer but not behavioral intentions.

Characteristics of participants in a televised smoking cessation intervention.

Participants in various components of a televised self-help smoking cessation program, based on the American Lung Association's Freedom From Smoking in 20 Days, are compared with a sample of the population of smokers to whom the intervention was addressed. Over 325,000 smokers in the target population were exposed to the program at some level. Most watched televised segments. Approximately 75,000 manuals were distributed and about 55,000 were used. Comparisons between participants and the targeted smoking population indicate that the intervention attracted those in the smoking population who are expected to be the majority of smokers by the Year 2000-blacks, females, and those with incomes under $13,000 per year. Participants with these characteristics were most likely to view the televised segments. Heavy smokers, females, and those with the most education were most likely to refer to the manual at least twice a week during the intervention. Older, nonblack participants and those with incomes of $13,000 or more per year were most likely to attend group support sessions outside the home. Overall, the patterns of association indicate that although a televised smoking cessation program can attract individuals similar to those projected to be smokers in 2000, participation in various components of the intervention will vary by demographic characteristics.

Some methodological cautions in the use of the Tolerance Questionnaire.

Both factor analysis and internal consistency analyses indicate that the items of the Tolerance Questionnaire do not form a unidimensional measure of an underlying construct. Implications of these findings are discussed. The importance of considering smoking rate, one of the scales' eight items, when interpreting validity correlations is emphasized.

The effects and use of maintenance newsletters in a smoking cessation intervention.

This article evaluates the effects and use of adjuncts to a televised smoking cessation program, based on the American Lung Association's "Freedom From Smoking in 20 Days." Subjects were randomized to maintenance and control conditions. The maintenance condition received newsletters with information and support addressing different stages in the cessation process and information about a telephone hotline. The maintenance condition did not increase cessation at any wave of interviewing, assessed by multiple point or point prevalence of abstinence. Those abstinent at 6 months and those who had made an attempt to stop smoking by that time were more likely to have used the newsletters and were more likely to have used the sections relevant to their cessation stage. Rates of use of the telephone hotline were low. The newsletters appear to be useful to smokers who are predisposed to use written materials.
