Dynamic effects of self-efficacy on smoking lapse and relapse.

Self-efficacy (SE) is thought to be critical to success in smoking cessation both as an individual difference and as a dynamic process after a quit attempt. In this study, 214 smokers used palm-top computers to record day-to-day variations in SE during 4 weeks after quitting. SE remained at high and stable levels prior to a 1st lapse but decreased and became more variable thereafter. The authors used event history models with time-varying covariates to assess the effect of daily SE on lapse and relapse risk. Daily SE measures predicted an initial lapse on the subsequent day. However, this relationship was accounted for by stable baseline differences in SE (assessed by questionnaire), rather than by day-to-day dynamics in SE. Progression from 1st lapse to relapse was also examined. In this instance, daily SE predicted subsequent relapse risk, even when baseline SE and concurrent smoking were accounted for, suggesting the importance of SE dynamics for this stage of the relapse process.     

Dynamic influences on smoking relapse process

This article describes a program of research applying Ecological Momentary Assessment (EMA) methods to study relapse to cigarette smoking, with a particular focus on the role of negative affect (NA) and self-efficacy (SE). Day-to-day changes in mood and stress did not predict lapse risk, but more proximal changes in affect were associated with lapses: Many lapses were marked by intense NA and by NA increases in the preceding hours. Individual differences in baseline SE predicted lapse risk, but daily SE was relatively stable during abstinence and did not influence lapse risk. However, lapses resulted in immediate drops in SE, and day-to-day changes in postlapse SE predicted progression to relapse, even after accounting for concurrent smoking. SE showed momentary drops associated with NA, but only among smokers with low baseline SE. Individual differences in baseline SE were only expressed situationally under conditions of NA. The findings highlight the importance of dynamic changes in background conditions and in immediate states as important influences on lapses and relapse and also suggest the importance of considering person by situation interactions.     

The acute effects of nicotine on positive and negative affect in adolescent smokers

Although adolescent cigarette smoking remains a critical public health concern, little is known about the reinforcing mechanisms governing smoking in this vulnerable population. To assess predictions derived from both positive and negative reinforcement models of drug use, the authors measured the acute effects of nicotine, as administered via tobacco cigarettes, on both positive and negative affect in a group of 15- to 18-year-old smokers. A matched group of nonsmokers served as a comparison group. Findings revealed that whereas adolescents who smoked a cigarette experienced reductions in both positive and negative affect, the observed reductions in negative affect were moderated by nicotine content of the cigarette (high yield vs. denicotinized), level of nicotine dependence, level of baseline craving, and smoking expectancies pertinent to negative affect regulation. Nonsmokers experienced no change in affect over the 10-min assessment period, and no interaction effects were observed for positive affect. Overall, the findings conform to a negative reinforcement model of nicotine effects and strongly suggest that, even among young light smokers, nicotine dependence and resultant withdrawal symptomatology may serve as motivating factors governing smoking behavior.     

Restorative effects of awe on negative affect after receiving negative performance feedback

The present study investigated the discrete positive effects of awe on negative job affect (NJA) arising from receiving negative performance feedback from a work supervisor or a co-worker. The participants were 131 business professionals and students at a large university in Kenya (females = 46%; age range 25 to 65 years). They participated in an experiment in which the emotion of awe was manipulated in an imagined situation where the participants received negative performance feedback from either a work supervisor or co-worker. Regression analyses of the data indicated that awe predicted a lower negative affect for negative feedback. Moreover, the indirect effects of the source of feedback on negative affect modulation were more significant for feedback received from co-workers than from supervisors. The positive emotion of awe may help one cope with negative performance feedback in a work setting.     

Dynamic self-efficacy and outcome expectancies: prediction of smoking lapse and relapse

According to social learning models of drug relapse, decreases in abstinence self-efficacy (ASE) and increases in positive smoking outcome expectancies (POEs) should foreshadow lapses and relapse. In this study, the authors examined this hypothesis by using ecological momentary assessment data from 305 smokers who achieved initial abstinence from smoking and monitored their smoking and their ASE and POEs by using palmtop computers. Daily ASE and POEs predicted the occurrence of a 1st lapse on the following day. Following a lapse, variations in daily ASE predicted the onset of relapse, even after controlling for concurrent smoking. ASE and POEs generally neither mediated nor moderated each other's effects. These data emphasize the role of dynamic factors in the relapse process.     

Subjective and reinforcing effects of smoking during negative mood induction

Two notions strongly held by many smokers are that negative mood increases smoking behavior and that this increase is due to the ability of smoking to alleviate negative affect. This study used a modified mood induction procedure to examine both the impact of smoking on induced mood, as well as the effect of induced mood on actual smoking behavior. Forty-eight smokers were randomly assigned to a smoking or a water-drinking comparison group. Each participant attended 3 sessions during which 1 of 3 mood states (positive, negative, or neutral) was induced. Contrary to expectation, smoking did not attenuate negative affect. However, negative mood induction subsequently quickened latency to smoke and increased number of puffs consumed ad lib.     

Pilot study of the effects of a workplace smoking ban on indices of smoking,cigarette craving,stress and other health behaviours

Abstract

Worksite smoking bans provide an ideal opportunity to examine the effects of enforced smoking restrictions on not only smoking behaviour, but also other health behaviours. This pilot study examines the short term effects of a such a ban on self-reported smoking behaviour, carbon monoxide and plasma cotinine levels and a number of other appetitive behaviours. The total number of cigarettes smoked on a working day and the number smoked just during working hours both declined following the introduction of a ban. Although the carbon monoxide levels of smokers during working hours demonstrated a similar trend to self-reported smoking, smokers' cotinine levels tended to increase, following an initial decrease following the ban. These data are suggestive of a compensatory process and a change in smoking topography, probably outside working hours. Measures of stress and craving also appeared to be affected by the introduction of smoking restrictions.     

Positive and negative affect produce opposing task-irrelevant stimulus preexposure effects

In three experiments, groups were exposed to either positive or negative affect video clips, after which they were presented with a series of task-irrelevant stimuli. In the subsequent test task, subjects were required to learn an association between the previously irrelevant stimulus and a consequence, and between a new stimulus and a consequence. Induced positive affect produced a latent inhibition effect (poorer evidence of learning with the previously irrelevant stimulus than with the novel stimulus). In opposition to this, induced negative affect resulted in better evidence of learning with a previously irrelevant stimulus than with a novel stimulus. In general, the opposing effects also were present in participants scoring high on self-report questionnaires of depression (Experiments 2 and 3). These unique findings were predicted and accounted for on the basis of two principles: (a) positive affect broadens the attentional field and negative affect contracts it; and (b) task-irrelevant stimuli are processed in two successive stages, the first encodes stimulus properties, and the second encodes stimulus relationships. The opposing influences of negative and positive mood on the processing of irrelevant stimuli have implications for the role of emotion in general theories of cognition, and possibly for resolving some of the inconsistent findings in research with schizophrenia patients.     

Perceived stress, quitting smoking, and smoking relapse

Assessed perceptions of stress prior to quitting and at 1, 3, and 6 months following quit date. Self-reported smoking status was augmented by a bogus pipeline procedure at each interview, and abstinence at 6 months was verified by carbon monoxide and saliva cotinine. The analyses provide strong evidence for a relation between changes in stress levels and changes in smoking status. Those who failed to quit smoking for more than 24 hr maintained a relatively high and consistent level of stress over the entire 6-month period. For those remaining continuously abstinent over the course of the study, stress decreased as duration of abstinence increased. Increases in stress with relapse were found across all three panel lags (prequit to 1 month, 1 to 3 months, and 3 to 6 months), and decreases in stress with quitting were found across the two lags where that comparison was possible. The possibility that the relation between smoking and stress is bidirectional is discussed as a possible interpretation of the results.     

Self-ratings of positive and negative affect and retrieval of positive and negative affect memories

Abstract

Based on analysis of self-ratings of mood, positive affect (PA) and negative affect (NA) have been proposed as basic, orthogonal mood dimensions (Watson & Tellegen, 1985). The present study asked subjects (N = 61) to not only provide self-ratings of PA and NA terms but also to retrieve personal memories associated with those terms. Self-rated PA was associated with latency to retrieve PA- but not NA-related memories; self-rated NA was associated with latency to retrieve NA- but not PA-related memories. Self-ratings of PA and NA were not significantly correlated, nor were retrieval latencies for PA and NA memories. Individual item correlations also revealed a strong direct relationship between self-ratings and retrieval latency. The dissociations involving a non-self report measure strengthen the distinction between PA and NA, and the individual item correlations are interpreted as showing that self-ratings of affect are based upon the ease of retrieval of personal memories.     

The effects of emotion regulation strategies on positive and negative affect in early adolescents

Recent research suggests that impaired emotion regulation (ER) may play an important role in the development of youth psychopathology. However, little research has explored the effects of ER strategies on affect in early adolescents. In Study 1 (n?=?76), we examined if early adolescents are able to use distraction and whether the effects of this strategy are similar to talking to one’s mother. In Study 2 (n?=?184), we compared the effects of distraction, cognitive reappraisal, acceptance, and rumination. In both studies, participants received instructions on how to regulate their emotions after a standardised negative mood induction. In general, the results indicated that distraction, but also cognitive reappraisal and acceptance, had promising short-term effects on positive and negative affect in early adolescents. These findings suggest that targeting adaptive ER skills, such as distraction, acceptance, and cognitive reappraisal, may be an important strategy to prevent or treat psychological problems in early adolescents.     

The independence of positive and negative affect depends on the affect measure

This study examined the degree of independence between Positive Affect (PA) and Negative Affect (NA) within a given situation. The affective state was measured before and after an experimentally induced success or failure experience in an anagram task. Two types of affect measures were used to assess PA and NA: the Positive and Negative Affect Schedule (PANAS) and a Pleasantness-Unpleasantness scale. Consistent with our hypotheses, results show that PA and NA are independent when measured with the PANAS but are correlated when assessed with the other scale. These PA-NA correlations differed significantly from each other before and after emotion induction, respectively. Additional analyses indicate that both PA scales are differentially sensitive to the mood induction procedure. The findings are discussed with respect to circumplex models of emotion.     

Error-related psychophysiology and negative affect

The error-related negativity (ERN/Ne) and error positivity (Pe) have been associated with error detection and response monitoring. More recently, heart rate (HR) and skin conductance (SC) have also been shown to be sensitive to the internal detection of errors. An enhanced ERN has consistently been observed in anxious subjects and there is some suggestion that the ERN is related to general negative affective experience (NA). The ERN has been source localized to the anterior cingulate cortex-a structure implicated in the regulation of affective, response selection, and autonomic resources. Thus, the findings that autonomic measures and affective distress are related to response monitoring are consistent with anterior cingulate cortex function. In the present experiment, we sought to evaluate more comprehensively the relationship between self-reported negative affect and error-related physiology in a between-groups design. Results indicate that high NA was associated with significantly greater ERN and error-related SCR, and smaller Pe. These results are discussed in terms of anterior cingulate cortex function, psychopathology, and response monitoring.     

Subtyping female adolescent psychiatric inpatients with features of eating disorders along dietary restraint and negative affect dimensions

Cluster-analytic studies of eating disorders in adult patients have yielded two subtypes (pure dietary and mixed dietary-negative affect). This study aimed to replicate the subtyping in female adolescent psychiatric inpatients with features of eating disorders. Cluster analyses of 137 patients with eating-disordered features revealed a dietary-negative affect subtype (43%) and a pure dietary subtype (57%). The dietary-negative affect subtype was characterized by greater likelihood of binge eating, greater eating-related psychopathology, and greater body image dissatisfaction. The two subtypes did not differ significantly in scores reflective of clinical syndromes (other than the significantly higher depressive affect in the negative affect subtype), but the dietary-negative affect subtype was characterized by greater personality disturbance and higher reported concerns in clinical areas, including suicidality and childhood abuse. The cluster analysis produced different results from an alternative approach to subtyping by vomiting. These findings provide further support for the reliability and validity of this subtyping scheme for eating pathology. Clinically, the findings suggest that the combination of dieting and negative affect signals a more disturbed variant of eating-disorder related psychopathology in female adolescent psychiatric inpatients.     

Smoking,stress, and negative affect: correlation,causation, and context across stages of smoking

This transdisciplinary review of the literature addresses the questions, Do stress and negative affect (NA) promote smoking? and Does smoking genuinely relieve stress and NA? Drawing on both human and animal literatures, the authors examine these questions across three developmental stages of smoking--initiation, maintenance, and relapse. Methodological and conceptual distinctions relating to within- and between-subjects levels of analyses are emphasized throughout the review. Potential mechanisms underlying links between stress and NA and smoking are also reviewed. Relative to direct-effect explanations, the authors argue that contextual mediator-moderator approaches hold greater potential for elucidating complex associations between NA and stress and smoking. The authors conclude with recommendations for research initiatives that draw on more sophisticated theories and methodologies.     

Dietary restraint and negative affect as mediators of body dissatisfaction and bulimic behavior in adolescent girls and boys.

Stice's dual pathway model of dietary restraint and negative affect was examined in both adolescent girls and boys. Self-report measures assessing body dissatisfaction, dietary restraint, negative affect and bulimic behavior were administered to 267 girls and 199 boys aged between 12 and 16 years. The findings for the girls were consistent with Stice's model, in that they indicated that both dietary restraint and negative affect mediated the relationship between body dissatisfaction and bulimic behavior. For the boys who desired a thinner body size, only negative affect was found to mediate the relationship between body dissatisfaction and bulimic behavior. On the other hand, for boys who desired a larger body size, both body dissatisfaction and dietary restraint were found to exert an independent effect on bulimic behavior. As boys can aspire to two contrasting and seemingly opposite body size ideals, the findings highlight that the relationship between body dissatisfaction, dietary restraint, negative affect and bulimic behavior are more complex in males than in females. Further research using longitudinal designs is needed in order to test the directional and bidirectional nature of the observed interrelationships.     

The causal effects of extraversion on positive affect and neuroticism on negative affect: Manipulating state extraversion and state neuroticism in an experimental approach

Although the relationships between extraversion and positive affect and between neuroticism and negative affect are powerful, the patterns of causality accounting for them are unknown. We employed an experimental methodology to manipulate state extraversion and state neuroticism to determine their causal status. In Experiment 1, state extraversion was manipulated by instructing participants to act extraverted and introverted during two different discussions with two other participants. Participants reported more positive affect when instructed to act extraverted than when instructed to act introverted, and this finding was supported by the ratings of observers. In Experiment 2, state neuroticism was manipulated by instructing participants to act neurotic and emotionally stable during two different discussions. Participants reported more negative affect when instructed to act neurotic than when instructed to act stable. Thus, at least some part of the extraversion-positive affect and neuroticism-negative affect relationships may be accounted for by the causal influences of extraverted behavior and neurotic behavior, respectively.
