Recent work indicates that increasing the drinking rate of a virtual bar-goer (VB) increases the rate of drinking for participants in a virtual reality (VR) bar environment. Here, we test the hypothesis that biopsychosocial factors including typical drinking pattern and expectancy that alcohol enhances social interactions would moderate this effect.
We assessed the drinking topography (DT) of participants (N=20) in a VR environment with a programmable VB during two testing sessions: one with a fast-drinking VB (30-60s sip interval) and one in which the VB drank slowly (60-120s sip interval). In this secondary analysis, linear mixed models were used to characterize potential interactions of typical daily alcohol intake (quantity-frequency index [QFI]), maximal alcohol consumed in one bout over the past six months (maxQ), Alcohol Use Disorder Identification Test (AUDIT) score, and expectancy that alcohol enhances social and physical pleasures (SPP) with time in simulation and condition on sip interval and volume.
Individuals with higher MaxQ showed a reduced effect of time on sip volume such that more intense recent binge episodes were associated with consistent drinking. Greater AUDIT scores were associated with lower sip intervals. In addition, greater SPP expectancy was associated with higher sip volumes, but only in the fast-drinking VB condition.
Greater drinking behavior and social expectancies were associated with more rapid drinking topography. In addition, findings suggest challenging alcohol outcome expectancies related to social enhancement could reduce alcohol-related risks by slowing the rate of alcohol intake in social situations.
最近的研究表明，增加虚拟酒吧酒客（VB）的饮酒速度会增加虚拟现实（VR）酒吧环境中参与者的饮酒速度。在这里，我们检验了这样一个假设，即包括典型饮酒模式和期望酒精能增强社交互动在内的生物心理社会因素会调节这种效应。
我们在两个测试会话中评估了参与者在 VR 环境中的饮酒模式（DT），其中一个 VB 饮酒速度较快（30-60 秒一口间隔），另一个 VB 饮酒速度较慢（60-120 秒一口间隔）。在这个二次分析中，我们使用线性混合模型来描述典型每日酒精摄入量（数量-频率指数[QFI]）、过去六个月中单次最大酒精摄入量（maxQ）、酒精使用障碍识别测试（AUDIT）得分以及期望酒精能增强社交和身体愉悦感（SPP）与模拟时间的交互作用，并对 sip 间隔和体积进行条件化处理。
MaxQ 较高的个体在 sip 体积上的时间效应降低，即最近更强烈的 binge 发作与持续饮酒有关。更高的 AUDIT 得分与更低的 sip 间隔有关。此外，更大的 SPP 期望与更高的 sip 体积有关，但仅在快速饮酒 VB 条件下。
更大的饮酒行为和社交期望与更快速的饮酒模式有关。此外，研究结果表明，挑战与社交增强相关的酒精结果期望可能会通过减缓社交情境中的饮酒速度来降低与酒精相关的风险。
