The role of positive urgency in alcohol-related risk-taking: An experimental investigation

Um, Miji 12 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / The relationship between positive urgency, a personality trait reflecting rash action during extreme positive emotional states, and risk-taking has previously been experimentally examined. However, how positive urgency is related to risk-taking while under the acute influence of alcohol has not been examined. The overarching goal of this dissertation was to generate behavioral evidence concerning how the interaction between positive urgency and alcohol consumption influences risk-taking via changes in emotional arousal. In this study, 59 community dwelling adults (mean age = 29.45 (SD = 10.96), 32.2% women, 78% White) completed mood induction procedures (positive or neutral) while consuming a beverage (alcohol or placebo) and then completed the Balloon Analogue Risk Task (BART) as a measure of risk-taking. The positive mood induction was effective in inducing high arousal positive emotions. Overall, study hypotheses were not supported; however, because of low power, effect sizes and patterns of relationship are reported. The relationship between positive urgency and risk-taking was positive and small in the positive mood condition but negative and small in the neutral mood condition. The alcohol group and the placebo group showed similar patterns of risk-taking that are positive and small. Finally, the relationship between positive urgency changes in emotional arousal was positive and small only in the positive/alcohol condition; however, there was no relationship between changes in emotional arousal and risk-taking. These findings suggest that, while changes in emotional arousal may result from a combination of positive urgency and alcohol consumption, it may not be a focal mechanism that explains the relationship between positive urgency and risk-taking. Further, positive urgency is a risk factor whether or not alcohol consumption is present. Although the small sample size limited the power to test the hypotheses, the effect size estimates obtained in this study provide preliminary data for a more properly powered future study. The pattern of findings suggests the viability of further developing the current positive mood induction to establish a lab-based paradigm for positive urgency and the use of a different experimental risk-taking task to examine positive emotion-based risk-taking.

Examination of a Bi-Directional Relationship between Urgency and Alcohol Use

Blackledge, Sabrina M. 12 1900 (has links)
The proposed study examined whether negative urgency and positive urgency are dynamic traits that hold bi-directional relationships with binge and prolonged alcohol use across time. Individuals between the ages of 18-30 were recruited from Amazon Mechanical Turk (MTurk; n = 179) and university student (n = 66) pools. Participants completed three batteries of self-report assessments approximately 30 days apart, each containing measures assessing negative and positive urgency, as well as drinking frequency and binge behavior during the prior month. Latent variable cross-lagged panel models examined the effects of alcohol use from the previous month on negative and positive urgency while controlling for concurrent and autoregressive effects. Results of the current study indicated that for the full sample, there was not an effect for the influence of binge/prolonged drinking on either negative or positive urgency during the subsequent month. However, when examined separately by sample (Turkers vs. university) and gender (male vs. female), significant effects were found more for individuals who were Turkers, male, and/or heavy drinkers, suggesting that increases in positive and negative urgency at Time 2 could be partially explained by variance in drinking patterns at Time 1 for these individuals. However, these relationships were not replicated again between Time 2 and Time 3 due to a decrease in all drinking behaviors during these times. Lastly, the study found that while urgency scores were related to psychosocial problems and dependence symptoms associated with drinking, there was no evidence to support that urgency scores had substantial relationships to specific frequency and/or bingeing behavior across the overall sample, although positive urgency had support for a relationship with bingeing, particularly among heavily drinking men. Thus, while the primary findings did not indicate any effects for a general sample of young adults, the effects observed among heavy male drinkers in the present study add to a growing body of literature indicating potential for interactive effects among personality, environmental, and sociobiological factors across the trajectory of the human lifespan. Future research that continues to examine urgency and how it relates to alcohol use in longitudinal contexts, utilizing diverse samples, is warranted.
