Behavioral economic (BE) approaches to understanding and reducing risky drinking among college students are well established, but little is known about the generalizability of prior findings to peers who currently are not traditional college students and are more difficult to reach for assessment and intervention. This cross-sectional survey investigated whether drinking practices and negative consequences were associated with greater alcohol demand, alcohol reward value, and delay discounting in this target population. Community-dwelling emerging adult drinkers aged 21 to 29 ( = 357) were recruited using Respondent-Driven Sampling adapted to a digital platform (age = 23.6 years, 64% women). Peers recruited peers in an iterative fashion. Participants completed a web-based survey of drinking practices, negative alcohol-related consequences, and BE measures of alcohol demand, alcohol reward value, and delay discounting. Regression analyses supported the study hypotheses. Higher alcohol demand (intensity and elasticity) predicted higher drinks per drinking day, more past-month drinking days, and more negative consequences. Higher alcohol reward value (discretionary alcohol spending and alcohol-involved activities) and stronger preference for sooner smaller versus later larger rewards predicted select drinking risk variables in the hypothesized direction ( < .05). BE risk characteristics were generalized to community-dwelling emerging adult risky drinkers, with the most consistent associations found between alcohol demand and drinking risk measures. The findings lay a foundation for extending successful BE interventions with college drinkers to this underserved population. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
行为经济学(BE)方法在理解和减少大学生的危险饮酒行为方面已经得到了很好的证实,但对于目前不属于传统大学生、更难进行评估和干预的同龄人,这些发现的普遍性知之甚少。本横断面调查研究了在这一目标人群中,饮酒行为和负面后果是否与更大的酒精需求、酒精奖励价值和延迟折扣有关。使用适应数字平台的响应驱动抽样(年龄= 23.6 岁,64%为女性)招募了年龄在 21 至 29 岁的社区居住的成年早期饮酒者(n=357)。同伴以迭代的方式招募同伴。参与者完成了一项关于饮酒行为、与酒精相关的负面后果以及酒精需求、酒精奖励价值和延迟折扣的 BE 测量的网络调查。回归分析支持了研究假设。更高的酒精需求(强度和弹性)预测更高的每日饮酒量、更多的过去一个月饮酒天数和更多的负面后果。更高的酒精奖励价值(任意性饮酒支出和涉及酒精的活动)和对尽早较小而非以后较大奖励的更强偏好预测了某些饮酒风险变量(<.05)。BE 风险特征已推广到社区居住的成年早期风险饮酒者,在酒精需求和饮酒风险测量之间发现了最一致的关联。这些发现为将成功的 BE 干预措施从大学生饮酒者扩展到这一未得到充分服务的人群奠定了基础。(PsycInfo 数据库记录(c)2021 APA,保留所有权利)。
