Smoking expectancies as mediators between dietary restraint and disinhibition and smoking in college women.

Women's beliefs about the appetite and weight control properties of cigarette smoking, dietary restraint and disinhibition, and smoking status were examined. As hypothesized, dietary restraint and disinhibition predicted appetite and weight control expectancies and smoking rate, such that women higher in dietary restraint and disinhibition reported stronger beliefs in the appetite and weight control properties of cigarettes and were more likely to be smoking than those lower in dietary restraint and disinhibition. Consistent with previous research, smoking expectancies for appetite and weight control predicted smoking status and smoking rate. Smoking expectancies for appetite and weight control were found to mediate the relationship between dietary restraint and smoking, and between disinhibition and smoking. This relationship between smoking and dietary constructs should be considered in smoking cessation and dietary interventions with young women.

Effects of an implicit mood prime on the accessibility of smoking expectancies in college women.

This study examined whether an implicit mood prime would differentially affect the accessibility of self-generated smoking expectancies in women. One hundred nine ever-smokers were randomly assigned to receive either a positive or negative musical mood induction or a no-music control condition. Participants self-generated smoking expectancies, and the 1st responses were categorized as positive reinforcement, negative reinforcement, or negative consequence expectancies. Overall, participants generated mood-congruent smoking expectancies, suggesting that affect may act as a conditioned stimulus that elicits expectations of positive and negative reinforcement of smoking behavior. In addition, negative reinforcement expectancies were more frequently generated in current versus past smokers. Results are consistent with a situational-specificity hypothesis and memory-based models of affect and expectancies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A comparison of the mediational properties of four adolescent smoking expectancy measures.

This prospective study compared the ability of 4 smoking expectancy measures to mediate the influence of peer, parent, and current smoking on adolescents' cigarette use 3 months later. No evidence for mediation was found when expectancies were operationalized as unidimensional subjective expected utility (SEU). multidimensional SEU, or unidimensional SEU decomposed into probability and desirability main effects and their interaction. Evidence for partial mediation was found for the decomposed multidimensional SEU measure. The results suggest that (a) peer and current cigarette use may influence future smoking indirectly through adolescents' probability estimates that smoking will control negative emotions and (b) the relationship between current and future smoking also may be mediated by adolescents' beliefs about the desirability of weight control.

Negative affect combines with smoking outcome expectancies to predict smoking behavior over time.

The present study examined whether the tendency to experience negative affective states combines with smoking outcome expectancies to predict smoking behavior over time. Participants were 121 young adults and resource people recruited from 3 alcohol and drug treatment programs and through community advertisements. Each participant completed 3 interviews over a 4-year period. Results indicated that dispositional negative affect and positive smoking expectancies were significantly correlated with smoking behavior both within and across time. Expectations of positive and negative reinforcement partially mediated negative affect's relation with smoking across time. Positive expectancies did not function as a moderator of negative affect's relation with smoking behavior. These results represent an important step in incorporating smoking outcome expectancies into multivariate models of smoking risk. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Mood-regulation expectancies as determinants of dysphoria in college students.

Predictors of coping styles, depression, and somatic symptoms in college students were examined. In previous research, the use of active and avoidant coping strategies was predicted by stress, family support, self-confidence, and easygoing disposition. This study found that the expectancy to be able to alter one's mood state added significantly to the prediction of coping. Mood-regulation expectancies also predicted dysphoria and somatic symptoms, even with the effects of coping behavior and other variables partialed out. Consistent with response expectancy theory of I. Kirsch (see PA, Vol 73:13702; see also 1990), these data indicate that besides affecting mood indirectly through their impact on coping behavior, expectancies can directly alter dysphoric moods. However, when the effects of expectancy were statistically controlled, active coping was positively associated with dysphoria, which suggests that coping strategies may not be effective unless they are believed in.

Do expectancies for reinforcement from smoking change after smoking initiation?

Expectancies are important predictors of smoking behavior. Recent research suggests that expectancies are not stable and vary across internal and external states and levels of cigarette consumption. Expectancies may also vary between individuals as a function of temperamental characteristics such as behavioral undercontrol (BU). Although pre-initiation expectancies have been linked to subsequent smoking behaviors, no study has assessed the effect of smoking initiation on expectancies. The present study was designed to test the hypotheses that both positive (PRE) and negative (NRE) reinforcement expectancies would increase following initiation, and that these changes would be moderated by BU. College students were interviewed 12–15 months apart. Those who initiated smoking between assessments (n = 69) were included in the present study. Linear mixed models showed a significant increase in PRE but not NRE from pre- to postinitiation. The relationship between NRE and time was moderated by BU, such that higher BU was associated with significantly larger post-initiation increases in NRE. Findings suggest that PRE and NRE change significantly following experience with smoking. Furthermore, undercontrolled, impulsive individuals may be particularly vulnerable to smoking with the intention of alleviating aversive states.

Programmed therapeutic messages as a smoking treatment adjunct: Reducing the impact of negative affect.

Maintaining treatment gains remains a challenge to smoking cessation programs. Smokers prone to negative affect are most likely to relapse. In an effort to improve maintenance, a standard cognitive behavioral treatment was supplemented with the provision of computer-controlled audiotape players containing personalized therapeutic messages. Either the standard treatment alone or the standard treatment plus 2 months use of the tape player were provided to 41 smokers. No outcome difference was found between the 2 conditions during the 1-year follow-up. (The combined 1-year abstinence rate was 61%, with 34% continuously abstinent.) The frequency with which participants used the device predicted both posttreatment coping skill use and smoking rate. Most notable was an interaction between treatment condition and negative affect. Provision of the devices negated or reversed the usual association between negative affect and poorer outcome. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predictors of brief smoking intervention in a midwifery setting

The aims of this study were: to assess current practice in smoking cessation interventions by midwives and to examine the relationship between the use of smoking intervention, practitioner characteristics and organizational factors. A mail-out survey was sent to a random sample of 500 midwives. The response rate was 85% (n = 425). The results indicated that most midwives used minimal interventions (advice and education) for at least some of their clients. However, the more skilled and more time-intensive forms of intervention such as counselling about methods to quit, negotiating a quit date and follow-up were infrequently utilized. Moreover, participants estimated that half their smoking clients were not offered any advice about smoking. Organizational factors such as: hospital policy for smoking intervention, type of hospital, size of hospital, cohesion of staff and work pressure predicted the use of smoking interventions. Self-reported ability to intervene for smoking and the level of assessment undertaken were practitioner characteristics which predicted the use of smoking interventions. The barriers that inhibit the use of smoking intervention by midwives are discussed and methods for change canvassed.     

The Smoking Consequences Questionnaire-Adult: Measurement of smoking outcome expectancies of experienced smokers.

The original Smoking Consequences Questionnaire (SCQ; T. H. Brandon & T. B. Baker, 1991) measured college students' outcome expectancies for cigarette smoking. A version (SCQ-Adult) was needed for assessing expectancies in more typical, older, nicotine-dependent smokers. Two separate versions of the SCQ were developed and compared. Tests of construct validity provided greater support for the version comprising probability items over the version comprising subjective expected utility items. As expected, principal components analyses revealed a greater number of factors than the original SCQ suggesting that expectancies become more specific with smoking experience. All scales showed good reliability. Over the course of smoking cessation treatment, expectancies became less positive, especially for abstaining participants. Other validity tests also tended to be consistent with research on alcohol expectancies and with contemporary models of drug outcome expectancies.

A fine-grained analysis of the role of self-efficacy in self-initiated attempts to quit smoking.

The relation between self-efficacy ratings and smoking behavior was explored among 36 people who were trying to quit smoking on their own. Ss self-monitored high-risk situations, coping efforts to withstand the temptation to smoke, and self-efficacy in coping with similar temptations for 4 weeks after quitting. Self-efficacy ratings were significantly related to the outcome of these situations, with Ss reporting higher efficacy ratings after situations in which they did not smoke as opposed to those in which they did smoke. Self-efficacy was predictive of smoking outcome, but there was considerable intersubject variability in the strength of the relation between efficacy and smoking behavior. Both efficacy and previous smoking behavior predicted smoking outcome equally well, however. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hassles, coping, and depressive symptoms in an elderly community sample: The role of mood regulation expectancies.

To extend research on the role of expectancy in coping, 96 individuals aged 65 yrs or older (M?=?74.46, SD?=?6.28) from non-nursing-home residential communities and organizations completed measures of daily hassles, situational coping responses, depressive symptoms, and generalized expectancies for negative mood regulation, defined as beliefs about one's ability to alleviate a negative mood. Scores from the Negative Mood Regulation Scale (S. J. Catanzaro and J. Mearns, 1990) were negatively associated with avoidant coping and depressive symptoms, independent of hassles and coping responses. As in college student samples, active coping was positively related to depressive symptoms, but only when negative mood regulation expectancies were controlled. The relations of hassles and expectancies with coping responses were weaker than those found previously in younger samples. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An ecological perspective on smoking among Asian American college students: The roles of social smoking and smoking motives.

Using electronic diaries, the present study examined the roles of social smoking and smoking motives in relation to cigarette use patterns among Asian American college smokers. Multilevel modeling results showed that participants smoked more cigarettes when smoking with peers than when smoking alone. Participants' coping (but not social) motives moderated the within-person associations between smoking with peers and the cigarettes smoked during a smoking episode. The findings support the utility of an ecological perspective in examining the dynamic interaction between smoking motives and the social settings of cigarette use, and call for further research on the social smoking behaviors in diverse populations.

Mono (S) hydroxy fatty acids: novel ligands for cytosolic actin

This study tested the hypothesis that the intensity of behavioral impairment under alcohol is related to social drinkers' expectancies about impairment and their rates of rise in blood alcohol concentration (BAC). After subjects (n = 30) were trained on a psychomotor task, they rated the impairment they expected from alcohol and then performed the task under alcohol (0.56 g/kg) or a placebo. Alcohol impaired performance, compared with placebo. Drinkers' expectations about impairment and their rates of rise in BAC were independent, and each factor predicted a significant portion of the variance in alcohol impairment among drinkers. More intense impairment under alcohol was associated with expectations of greater impairment and with swifter rates of rise in BAC. BACs obtained by drinkers during task performance were not related to the intensity of impairment they displayed. The study shows that a pharmacological and nonpharmacological variable can each affect a drinker's behavioral impairment under alcohol, and this finding contributes to our understanding of conditions where BAC per se may be an unreliable indicator of impairment.     

Maintenance of smoking cessation: Effect of follow-up letters, smoking motivation, muscle tension, and health locus of control.

Following smoking-cessation treatment, half of 44 Ss (22–58 yrs) were sent supportive maintenance letters. Letters produced no main effect but reduced smoking in Ss who smoked from habit or who received little pleasure from the sensorimotor stimulation of smoking, perhaps by increasing their awareness of smoking. Letters also reduced smoking in Ss with high muscle tension. Letters increased smoking among opposite S groups and in those believing powerful others could not influence their health. Independent of letter receipt, maintenance was enhanced by internal health locus of control (Multidimensional Health Locus of Control) and hampered by chance control expectancies.

Smokers' expectancies for smoking versus nicotine.

This study compared smokers' expectancies for the full act of smoking with those for nicotine per se by means of a word association task. Smokers (N = 201) were randomized to receive instructions to complete either "Smoking makes one ____." or "Nicotine makes one ____." with as many words as possible within 30 s. Results indicated that smokers held similar expectancies for smoking and nicotine; however, negative consequences (e.g., health risks) were more associated with smoking than with nicotine, and addiction expectancies were more associated with nicotine than with smoking. These findings suggest that smokers have a more realistic conceptualization of nicotine's role in smoking than had been indicated from earlier surveys. These findings have important implications for both nicotine-based and behavioral interventions, as well as for experimental designs that rely upon the perceived manipulation of nicotine content.

Smoking outcome expectancies: Factor structure, predictive validity, and discriminant validity.

Recent models of addiction posit that drug outcome expectancies are influential determinants of drug use. The current research examines the dimensional structure, predictive validity, and discriminant validity of expectancies for cigarette smoking in a prospective study. There was a good fit between the factor structure of the Smoking Consequences Questionnaire and the observed data. In addition, the internal consistency of each scale was satisfactory. Moreover, there was considerable evidence for the predictive and discriminant validity of expectancies. Expectancies of positive outcomes (positive reinforcement, negative reinforcement, and appetite-weight control) predicted withdrawal severity. Negative reinforcement expectancies and expectancies of negative consequences predicted cessation success. Predictive relations remained significant after controlling for related constructs: negative affect, stress, and dependence measures.

Self-efficacy and smoking reexamined: Construct validity and clinical utility.

131 clients (mean age 39 yrs) in a smoking cessation program rated their confidence (self-efficacy) in their ability to resist smoking at the end of treatment and throughout a 6-mo follow-up period. Consistent with previous findings, posttreatment scores significantly predicted subsequent smoking status. When concurrent smoking was partialed out, efficacy remained predictive but to a much lesser degree. The partial correlations also indicated that when pitted against concurrent smoking, confidence scores retain some unique predictive power but do not operate as a powerful mediator of the effects of concurrent behavior. Factor analysis of posttreatment scores revealed that efficacy ratings are primarily unidimensional and not situation specific. Efficacy ratings made 2 mo after treatment were quite predictive of future relapse. These analyses suggest that efficacy ratings, although generally not a mediating variable, can be useful predictors of relapse, particularly when assessed during the maintenance phase of treatment.

The influence of situation and coping on relapse crisis outcomes after smoking cessation.

Examines the influence of situational characteristics and coping on the outcome of a relapse crisis for 232 Ss followed for 1 month after a self-initiated smoking cessation attempt. Survival of a relapse crisis was most strongly related to the number of coping strategies used. All coping strategies were equally effective; furthermore, combining cognitive and behavioral coping strategies was not more effective than using multiple cognitive or multiple behavioral strategies. During the second half of the follow-up period (Weeks 3 and 4 postcessation), the presence of smokers resulted in a decreased likelihood of coping and an increased likelihood of smoking. In addition, active coping was marginally related to higher baseline levels of motivation to quit. When motivation and the presence of smokers were controlled, however, coping still significantly predicted outcome. Results are discussed with reference to previous relapse studies.
