An examination of mood effects on positive alcohol expectancies among undergraduate drinkers

The influence of negative urgency and mood inductions on alcohol cognitions

BACKGROUND

Negative urgency (NU), the tendency to act rashly during negative emotional states, is a robust risk factor for alcohol misuse that is posited to function in part through alcohol-related cognitions. Nonetheless, relatively little research has examined mood-based fluctuations in such cognitions, which could help to explain how the trait of NU translates to impulsive alcohol-related behaviors. We examined how NU impacted several alcohol cognitions (positive/negative alcohol expectancies, positive/negative alcohol valuations, and alcohol craving for positive/negative emotional reinforcement) before and after negative, neutral, or positive mood inductions. We hypothesized that NU would predict greater and more favorable endorsement of alcohol and its effects following negative (vs. positive or neutral) mood induction.

METHODS

Participants (N = 428) were southern-midwestern college students recruited for an online experiment. Following the provision of consent, participants rated NU and preinduction alcohol cognitions, and were then randomly assigned to one of three (negative, neutral, or positive) mood inductions; subsequently, postinduction alcohol-cognition ratings were immediately obtained. We conducted six robust multilevel linear models (one per DV) examining NU's influence on within-person changes in alcohol cognitions across each mood induction.

RESULTS

No three-way interactions were identified and only one two-way interaction involving NU was identified. There were main effects across mood induction conditions and time points for NU predicting greater endorsement of positive and negative alcohol outcome expectancies, and greater alcohol craving for positive and negative emotional reinforcement.

CONCLUSIONS

Greater NU predicts greater perceived likelihood of alcohol's effects, alongside greater desire for mood improvement from alcohol. The absence of three-way interactive effects indicates NU's influence on mood-dependent fluctuations in alcohol cognitions may manifest over longer timescales (e.g., months and years), involve alternative cognitive processes (e.g., drinking motives and implicit alcohol cognitions), and apply more broadly to desires for mood improvement than purely negative emotional reinforcement.

Induced negative affect's impact on self-reported cannabis use, expectancies, and problems

Substance use disorders and affective disturbances often covary. Even momentary experiences of negative affect (NA) appear linked with substance use. While strong evidence of these relations exists, NA might bias endorsements of substance use due to hindered recall and reporting processes. This hypothesis warrants further research, as accurate assessment of substance-related variables is crucial in both research and treatment settings. The present study examined the influence of NA on reporting of cannabis variables using an affect-induction paradigm. Over 700 individuals recruited from Amazon's MTurk participated. After reporting demographics and baseline affect, participants were randomly assigned to either a NA induction or control condition. Follow-up measures assessed post-induction affect and cannabis-related variables. Results revealed that the NA induction task significantly increased NA and decreased positive affect relative to the control condition. Participants assigned to the NA induction reported greater negative cannabis expectancies and more cannabis problems, even after controlling for age and educational attainment. Cannabis use and cannabis problems appeared positively related. Future research should continue to assess for the influence of NA in reporting of cannabis variables. Should subsequent work find differences in reporting of substance use that appear to covary with negative affect, clinicians and researchers alike should be mindful of the implications of potentially biased reporting on assessment, intervention, and research outcomes.

The Relationship Between Psychological Distress, Negative Cognitions, and Expectancies on Problem Drinking: Exploring a Growing Problem Among University Students

Few studies have sought to understand the concurrent relationship between cognitive and affective processes on alcohol use and negative alcohol-related consequences, despite both being identified as predictive risk factors in the college population. More research is needed to understand the relationships between identified factors of problem drinking among this at-risk population. The purpose of this study was to test if the relationship between psychological distress and problem drinking among university students (N = 284; M-age = 19.77) was mediated by negative affect regulation strategies and positive alcohol-related expectancies. Two latent mediation models of problem drinking were tested using structural equation modeling (SEM). The parsimonious three-path mediated latent model was supported by the data, as evidenced by several model fit indices. Furthermore, the alternate saturated model provided similar fit to the data, but contained several direct relationships that were not statistically significant. The relationship between psychological distress and problem drinking was mediated by an extended contributory chain, including negative affect regulation and positive alcohol-related expectancies. Implications for prevention and treatment, as well as future directions, are discussed.

Mood and implicit alcohol expectancy processes: predicting alcohol consumption in the laboratory

BACKGROUND

Implicit positive alcohol expectancy (PAE) processes are thought to respond phasically to external and internal stimuli-including mood states-and so they may exert powerful proximal influences over drinking behavior. Although social learning theory contends that mood states activate mood-congruent implicit PAEs, which in turn lead to alcohol use, there is a dearth of experimental research examining this mediation model relative to observable drinking. Moreover, an expectancy theory perspective might suggest that, rather than influencing PAEs directly, mood may moderate the association between PAEs and drinking. To test these models, this study examined the role of mood in the association between implicitly measured PAE processes (i.e., latency to endorse PAEs) and immediate alcohol consumption in the laboratory. Gender differences in these processes also were examined.

METHOD

College students (N = 146) were exposed to either a positive, negative, or neutral mood induction procedure, completed a computerized PAE reaction time (RT) task, and subsequently consumed alcohol ad libitum.

RESULTS

The mood manipulation had no direct effects on drinking in the laboratory, making the mediation hypothesis irrelevant. Instead, gender and mood condition moderated the association between RT to endorse PAEs and drinking in the laboratory. For males, RT to tension reduction PAEs was a stronger predictor of volume of beer consumed and peak blood alcohol concentration in the context of general arousal (i.e., positive and negative mood) relative to neutral mood. RT to PAEs did not predict drinking in the laboratory for females.

CONCLUSIONS

The results show that PAE processes are important determinants of immediate drinking behavior in men, suggesting that biased attention to mood-relevant PAEs-as indicated by longer RTs-predicts greater alcohol consumption in the appropriate mood context. The findings also highlight the need to consider gender differences in PAE processes. This study underscores the need for interventions that target automatic cognitive processes related to alcohol use.

Emotional reactivity across individuals with varying trauma and substance dependence histories

BACKGROUND: Research has reported a high rate of substance dependence in traumatized individuals who do not develop PTSD (TWP). While past studies have failed to consistently demonstrate that TWP individuals experience PTSD symptoms, findings have indicated that TWP and a history of substance dependence aside from nicotine dependence (SDH) are linked to affect disruption. AIMS: The present study explored positive and negative affective mechanisms across four groups with varying SDH and TWP including TWP + SDH, TWP only, SDH only, or no history. Researchers hypothesized that adults (n = 78) would be more emotionally reactive to an experimentally-induced negative mood compared to a neutral mood induction as the presence of co-existing TWP and SDH increased. METHOD: After a brief telephone screening, eligible participants completed baseline self-report questionnaires and experimentally-manipulated negative and neutral mood inductions. RESULTS: Most notably, results showed a significant TWP x SDH x Mood induction interaction (F (1, 63) = 4.154; Mse = 51.999; p = .046) for positive affect responses. Simple effects indicated that all participants except TWP + SDH individuals experienced a significant decrease in positive affect during the negative compared to the neutral mood condition. CONCLUSION: Findings may identify a protective mechanism for relapse among individuals with a history of both TWP and SDH.

Trauma exposure influences cue elicited affective responses among smokers with and without a history of major depression

The current study tested the emotional reactivity of smokers with and without histories of major depression (MDD Hx) and trauma exposure (TE). Four counterbalanced conditions nested negative (e.g., dysphoric) or neutral mood inductions with in vivo versus control smoking paraphernalia cues (Neutral+Control; Neutral+Cigarette; Neg+Control; Neg+Cigarette). Mixed model analysis of covariance (ANCOVA) tested between and within subjects differences in negative affective symptoms pre- to post-exposure across four groups (TE+MDD Hx; TE only; MDD Hx only; no history). Results produced two notable effects. First, TE only individuals endorsed the greatest increase in depressive symptoms across both negative mood induction conditions (regardless of smoking paraphernalia) compared with other groups. Second, dual history participants (TE+MDD Hx) show a potentiated depressive response to the Neg+Cigarette condition compared with the Neg+Control condition. Implications to a depression-specific negative affective vulnerability among TE only smokers that is independent of MDD Hx and greater than smokers with a MDD Hx are discussed.

Relationships between alcohol-related memory association and changes in mood: systematic differences between high- and low-risk drinkers

Heavy alcohol use is common in undergraduates and is associated with health-risk behaviors, negative consequences, and increased risk for future alcohol dependence. Alcohol-related memory associations (AMAs) and mood changes are independently related to student drinking, but more research on how these variables interact is needed.

AIMS

To examine (i) how AMAs predict drinking behavior after accounting for depression, and (ii) how changes in negative and positive mood predict AMAs among low- and high-risk drinkers.

METHODS

Positive and negative moods were manipulated using a musical mood induction procedure immediately prior to completion of memory association measures. A bootstrapped structural equation model was tested, permitting a sampling distribution free of the requirement of normality.

RESULTS

Negative mood changes predicted AMAs in high-risk drinkers but not in low-risk drinkers, and the opposite was found for positive mood changes.

CONCLUSION

The negative mood-AMA association appeared related to risky drinking, and these subtle implicit cognitive processes may warrant a special focus in intervention programs for high-risk drinkers.

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.

Mood-Induced Increases in Alcohol Expectancy Strength in Internally Motivated Drinkers

This study investigated whether exposure to musical mood induction procedures (MMIP) differentially increases the strength of specific alcohol expectancies for coping motivated (CM) versus enhancement motivated (EM) drinkers. Participants were 86 undergraduates who had elevated scores on either the CM or EM subscale of the Drinking Motives Questionnaire (M. L. Cooper, 1994). Participants were randomly assigned to either a positive or negative mood condition. The Alcohol Craving Questionnaire (E. G. Singleton, S. T. Tiffany, & J. E. Henningfield, 1994) was administered at baseline and after MMIP to assess phasic changes in alcohol expectancy strength. Consistent with hypotheses, only CM drinkers in the negative mood condition reported increased relief expectancies, and only EM drinkers in the positive mood condition reported increased reward expectancies. Theoretical and clinical implications are discussed.

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.
