Social networks are important predictors of alcohol-related outcomes, especially among those with a DUI where riskier social networks are associated with increased risk of drinking and driving. Social networks are increasingly a target for intervention; however, no studies have examined and measured whether longitudinal changes in social networks are associated with reductions in impaired driving.
The current study first examines longitudinal changes in social networks among participants receiving services following a first-time DUI, and then examines the association between network change and drinking outcomes at 4- and 10-month follow-up.
The study surveyed a subsample of participants (N = 94) enrolled in a clinical trial of individuals randomized to cognitive behavioral therapy (CBT) or usual care (UC) on an iPad using EgoWeb 2.0-an egocentric social network data collection software-about pre-DUI and post-DUI networks and their short- and long-term drinking behaviors.
Participants were 65% male, 48% Hispanic, and an average of 32.5 years old. Overall, participants significantly reduced the proportion of network members with whom they drank from 0.41 to 0.30 (p = .001) and with whom they drank more alcohol than they wanted to from 0.15 to 0.07 (p = .0001) from two weeks prior to the DUI (measured at baseline) to 4-month follow-up. Furthermore, decreases in proportion of drinking partners over time were associated with reduced drinks per week, self-reported driving after drinking, and intentions to drive after drinking at 4-month follow-up. Participants who reported decreases in proportion of drinking partners also reported significantly less binge drinking at 10-month follow-up. Finally, increases in emotional support were associated with decreases in binge drinking at 4-month follow-up. The study found no differences in the changes in composition of networks between CBT and UC groups.
These results suggest that individuals receiving services in DUI programs significantly reduced risky network members over time and that these social network changes were associated with reduced drinking and other indicators of risk for DUI recidivism. Clinical interventions that target reductions in risky network members may improve outcomes for those enrolled in a DUI program.
社交网络是酒精相关结果的重要预测因素，尤其是对于那些有 DUI 记录的人来说，风险较高的社交网络与增加饮酒和驾驶的风险有关。社交网络越来越成为干预的目标；然而，尚无研究检验和衡量社交网络的纵向变化是否与减少不良驾驶有关。
本研究首先检查了首次 DUI 后接受服务的参与者的社交网络的纵向变化，然后检验了网络变化与 4 个月和 10 个月随访时饮酒结果之间的关联。
该研究使用 EgoWeb 2.0（一种以自我为中心的社交网络数据收集软件），对参加认知行为疗法（CBT）或常规护理（UC）随机分组的个体的临床试验中的亚样本（N=94）进行调查，以了解他们在 DUI 前和 DUI 后的网络情况以及他们的短期和长期饮酒行为。
参与者中 65%为男性，48%为西班牙裔，平均年龄为 32.5 岁。总体而言，参与者显著减少了与他们一起饮酒的网络成员的比例，从 DUI 前两周（基线测量）的 0.41 降至 0.30（p=0.001），与他们一起饮酒的比例也从 0.15 降至 0.07（p=0.0001）。此外，随着时间的推移，与饮酒伙伴的比例下降与 4 个月随访时每周饮酒量、饮酒后驾车以及酒后驾车意图减少有关。报告与饮酒伙伴比例下降的参与者也报告在 10 个月随访时 binge 饮酒明显减少。最后，情绪支持的增加与 4 个月随访时 binge 饮酒的减少有关。研究发现，CBT 和 UC 组之间网络组成的变化没有差异。
这些结果表明，在 DUI 项目中接受服务的个体随着时间的推移显著减少了风险较高的网络成员，这些社交网络变化与饮酒量减少和 DUI 再犯风险的其他指标有关。针对减少风险网络成员的临床干预措施可能会改善参加 DUI 项目的人的治疗效果。
