The effect of body image threat on smoking motivation among college women: Mediation by negative affect.

A recent experimental study found that activation of negative body image cognitions produced urges to smoke in young women (E. N. Lopez, D. J. Drobes, J. K. Thompson, & T. H. Brandon, 2008). This study intended to replicate and extend these experimental findings by examining the role of negative affect as a mediator of the relationship between body dissatisfaction and smoking urges. Female college smokers (N = 133) were randomly assigned to a body image challenge (trying on a bathing suit) or a control condition (evaluating a purse). State levels of urge to smoke, mood, and body dissatisfaction were assessed both pre- and postmanipulation. Trying on a bathing suit increased body dissatisfaction and reported urges to smoke, particularly those urges related to reducing negative affect. Additionally, state negative affect mediated the relationship between the body image manipulation and smoking urge. This study provides additional support, through an experimental design, that situational challenges to body image influence smoking motivation and that this effect occurs, at least in part, through increases in negative affect. Theoretical and applied implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affective individual differences and startle reflex modulation.

Potentiation of startle has been demonstrated in experimentally produced aversive emotional states, and clinical reports suggest that potentiated startle may be associated with fear or anxiety. To test the generalizability of startle potentiation across a variety of emotional states as well as its sensitivity to individual differences in fearfulness, the acoustic startle response of 17 high- and 15 low-fear adult Ss was assessed during fear, anger, joy, sadness, pleasant relaxation, and neutral imagery. Startle responses were larger in all aversive affective states than during pleasant imagery. This effect was enhanced among high fear Ss, although follow-up testing indicated that other affective individual differences (depression and anger) may also be related to increased potentiation of startle in negative affect. Startle latency was reduced during high- rather than low-arousal imagery but was unaffected by emotional valence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Daily Processes in Stress and Smoking: Effects of Negative Events, Nicotine Dependence, and Gender.

The author used a multilevel daily process design to examine relations among daily negative events, perceived stress, smoking, and smoking urges. The moderating effects of gender and nicotine dependence were also explored. Fifty-one adult community-residing smokers recorded negative events, perceived stress, cigarette smoking, and urges to smoke 4 times daily for 14 days. Analyses of within-person relations showed that participants smoked more cigarettes and experienced more urges to smoke on occasions with higher numbers of negative events and higher levels of perceived stress. These relations were stronger for men than for women. Nicotine dependence did not interact with events or stress in predicting smoking or urges. These findings build on laboratory studies and cross-sectional surveys by showing that in naturalistic settings, occasions with negative events and perceived stress are associated with smoking and urges to smoke.

Relation between self-reported affect and drug urges and cravings in continuing and withdrawing smokers.

Investigated, in 2 experiments, the effects of withdrawal and stress on the affective correlates of urges to smoke. In both, habitual cigarette smokers were divided into continuing and withdrawing smoker groups. In the 1st study, 44 adults reported current mood, urge, and expectations over a 24-hr period. In the 2nd, a controlled laboratory study, urge, affect, and physiological data were obtained from continuing and withdrawing groups (N?=?64) exposed to high- or low-stress conditions. Urges among withdrawing smokers were positively associated with negative affect and negatively associated with positive affect; continuing smokers reported urges that were directly associated with positive affect and unrelated to negative affect. Stress and withdrawal produced urge and self-reports that were related to negative affect. Moreover, Ss who smoked after exposure to withdrawal and stress reported greater pleasure and arousal than did other Ss. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Testing the influence of external and internal cues on smoking motivation using a community sample.

Exposing smokers to either external cues (e.g., pictures of cigarettes) or internal cues (e.g., negative affect induction) can induce urge to smoke and other behavioral and physiological responses. However, little is known about whether the two types of cues interact when presented in close proximity, as is likely the case in the real word. Additionally, potential moderators of cue reactivity have rarely been examined. Finally, few cue-reactivity studies have used representative samples of smokers. In a randomized 2 × 2 crossed factorial between-subjects design, the current study tested the effects of a negative affect cue intended to produce anxiety (speech preparation task) and an external smoking cue on urge and behavioral reactivity in a community sample of adult smokers (N = 175), and whether trait impulsivity moderated the effects. Both types of cues produced main effects on urges to smoke, despite the speech task failing to increase anxiety significantly. The speech task increased smoking urge related to anticipation of negative affect relief, whereas the external smoking cues increased urges related to anticipation of pleasure; however, the cues did not interact. Impulsivity measures predicted urge and other smoking-related variables, but did not moderate cue-reactivity. Results suggest independent rather than synergistic effects of these contributors to smoking motivation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of nicotine deprivation on alcohol-related information processing and drinking behavior.

This study examined the influence of smoking cues and nicotine deprivation on responses to alcohol among hazardous drinkers. Fifty-six daily smoking, hazardous drinkers were exposed to either smoking cues or control cues after either 6 hr of nicotine deprivation or no deprivation. Urges to drink alcohol, alcohol-related cognitive processing, and alcohol consumption were assessed after cue exposure. Results indicated that nicotine deprivation increased urges to drink, the accessibility of alcohol outcome expectancies, and the volume of alcohol consumed. There was little influence of the smoking cue manipulation on these processes. Implications for understanding the mechanisms underlying alcohol–tobacco interactions are discussed.

Manipulating self-efficacy in the exercise environment in women: Influences on affective responses.

Self-efficacy was experimentally manipulated in an exercise context, and its effect on affective responses was examined. College women (N?=?46) were randomly assigned to a high- or low-efficacy condition, and efficacy expectations were manipulated by means of bogus feedback and graphs depicting contrived normative data. The manipulation successfully influenced affective responses, with participants in the high-efficacy group reporting more positive and less negative affect than did the low-efficacy group. Efficacy was significantly related to feeling-state responses during and after activity but only in the high-efficacy condition. The results suggest that self-efficacy can be manipulated and that these changes are related to the affective experience associated with exercise. Such findings may have important implications for the roles played by self-efficacy and affect in exercise adherence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Imagery-Induced Tobacco Craving: Duration and Lack of Assessment Reactivity Bias.

The duration of imagery-induced tobacco craving and whether craving responses are biased by repeated assessment (reactivity) was studied. Nonabstinent smokers (n = 40) either imagined a scene describing smoking urges or rested. They then either completed the Tobacco Craving Questionnaire (TCQ; S. J. Heishman, E. G. Singleton, & E. T. Moolchan, 2003) every minute for 15 min or completed it after imagery or rest (Minute 1) and 15 min later. TCQ scores were greater after imagery compared with rest and remained significantly elevated at Minute 15. There was no evidence that TCQ responses were affected by repeated measurement. These data suggest that imagery-induced craving can persist for at least 15 min and that craving responses are not biased by assessment reactivity.

Prolonged duration of craving, mood, and autonomic responses elicited by cues and imagery in smokers: Effects of tobacco deprivation and sex.

Increases in self-reported craving and changes in autonomic functioning are reliably elicited when smokers are exposed to tobacco-related stimuli compared with neutral stimuli. However, few studies have reported the time course of cue-elicited craving or have directly compared the effectiveness of smoking cues versus imagery to evoke a craving response. In addition to these two issues, we investigated the influence of tobacco deprivation and sex on craving, mood, and autonomic responses. Sixty cigarette smokers (30 men, 30 women) were tested in two counterbalanced sessions, one after overnight tobacco deprivation and one during ad libitum smoking. At each session, participants were exposed to four randomized experimental trials: smoking imagery, neutral imagery, smoking cues, and neutral cues. Tobacco craving and mood were assessed repeatedly and physiological measures were recorded continuously for 30 min after imagery or cue exposure. Compared with neutral trials, smoking cues and smoking imagery reliably increased tobacco craving, negative mood, heart rate, and blood pressure and decreased positive mood ratings. Changes were observed immediately after cue and imagery presentation and remained unchanged for 30 min. Responding was greater in the nondeprived condition, and cues elicited more robust responding than imagery for most measures. Women responded more robustly to smoking cues only in the nondeprived condition, whereas imagery evoked greater responses in men during both conditions. These findings provide new data on the time course, magnitude, and tobacco deprivation effects on elicited craving. Sex differences were dependent on stimulus type and deprivation condition.

Cue-elicited negative affect in impulsive smokers.

Impulsivity is associated with cigarette smoking, but the nature of this relationship and the mechanisms that maintain it are relatively unknown. The relationship has often been thought to reflect appetitive processes, but research suggests that an affective pathway exists as well. The present study tested the effect of impulsivity on affective responses to an environmental smoking cue. Adult smokers (N=62) were exposed to a neutral cue and a smoking cue in separate experimental sessions in a repeated-measures design. Mixed-effects regression analyses showed that larger postexposure increases in negative affect were associated with high scores on 2 facets of impulsivity: urgency, t(179)=6.16, p     

Impact of causal attributions on affective reactions to success and failure.

Assessed the impact of outcome (success vs failure) and attribution (internal vs external) on affect in an achievement setting. Following the theorizing of B. Weiner et al (1978, 1979), it was anticipated that the outcome manipulation would determine general positive and negative affective reactions, whereas the attribution manipulation would influence affects related to self-esteem. 53 female undergraduates received success or failure feedback on a social accuracy test and were induced to attribute their performance to either an internal (ability) or an external cause (characteristics of the task). A factor analysis revealed 3 dimensions: Negative Affect, Positive Affect, and Self-Esteem. ANOVA indicated that the nature of the attribution influenced all 3 forms of affective reactions. Success produced greater positive affect, less negative affect, and higher self-esteem than failure only when ability attributions were induced. Although additional analyses offered some support for the presence of affects influenced solely by outcome, the majority of analyses supported the notion that attributions are the primary determinants of affective reactions to success and failure.

Affect, cognition, and awareness: Affective priming with optimal and suboptimal stimulus exposures.

The affective primacy hypothesis (R. B. Zajonc, 1980) asserts that positive and negative affective reactions can be evoked with minimal stimulus input and virtually no cognitive processing. This hypothesis was tested by comparing the effects of affective and cognitive priming under extremely brief (suboptimal) and longer (optimal) exposure durations. At suboptimal exposures only affective primes produced significant shifts in Ss' judgments of novel stimuli. Results suggest that when affect is elicited outside of conscious awareness, it is diffuse and nonspecific, and its origin and address are not accessible. Having minimal cognitive participation, such gross and nonspecific affective reactions can therefore be diffused or displaced onto unrelated stimuli. At optimal exposures this pattern of results was reversed such that only cognitive primes produced significant shifts in judgments. Together, these results support the affective primacy hypothesis.

Affect, expectancies, urges, and smoking: Do they conform to models of drug motivation and relapse?

Social-learning models of drug motivation and relapse often include the constructs of affect and drug expectancies. Most research has taken a molar approach to examining relations between these constructs and level of drug use. An experiment examined the roles of affect and expectancies in multiple measures of situation-specific motivation to smoke tobacco. Undergraduate smokers (n?=?101) received either a positive or negative mood manipulation (false feedback on an intelligence test). Self-reported urge was influenced by both negative affect and expectancies for positive reinforcement from smoking. Actual consumption was related only to smoking expectancies and only among abstaining smokers. affect by expectancy interactions were also found. Findings support a limited role of affect and expectancies in smoking motivation. Poor coherence among the motivational indexes challenges the assumptions of existing models of drug motivation.

Cumulative effects of induced affective states in children: Accentuation, inoculation, and remediation.

Little is known about the specific and potentially interactive impact of successive affect-inducing experiences. In the present study, 144 4- and 5-yr-old preschool children experienced 2 standard experimental affect inductions in succession, and the effects were assessed on self-gratification, altruism, cognitive processing, and expressed affect. The states induced were happy, sad, or neutral, and the repeated inductions were either consistent or inconsistent. The findings are as follows: (a) Only the 1st of the 2 affect inductions had an effect on self-gratification or altruism, with sad states increasing self-gratification and decreasing altruism. There was no indication that a 2nd affect-inducing experience could remediate the behavioral consequences of a prior one. (b) Generative cognitive processing was increased by both the ongoing affective state and the affective content of the material to be generated. Positive affect states or content increased the speed of processing. (c) Ss' memory for the thoughts they had produced was influenced also by affective state, with sad states increasing the latency for recall.

Smoking patterns and dependence: Contrasting chippers and heavy smokers.

The authors used ecological momentary assessment to contrast smoking patterns among chippers (CHs; n = 26)--smokers who smoke despite an apparent absence of tobacco dependence--with those seen in heavy smokers (HSs; n = 28). Smoking and nonsmoking settings (activity, mood, etc.) were assessed by means of electronic diary. CHs were not social smokers; like HSs, they smoked half their cigarettes while alone. When smoking, CHs' urge levels equaled those of HSs; between cigarettes, CHs had few urges, whereas HSs reported moderate urges. CHs' smoking was particularly associated with indulgent activities: relaxation, socializing, eating, and drinking alcohol. Outside of these indulgent settings, CHs' (but not HSs') smoking was associated with negative affect. In idiographic analyses, CHs' smoking was under much stronger stimulus control than was that of HSs. The authors propose that the disappearance of stimulus control over use is a characteristic of dependence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
