Abstract

BACKGROUND

Alcohol misuse is a major health concern among military members. Reserve component members face unique barriers as they live off base with limited access to behavioral health services. Web and app-based brief interventions are a promising means to improve access to treatment for those who misuse alcohol, with the use of booster sessions to enhance effectiveness, solidify gains, and reinforce changes. However, little is known about who will engage in booster sessions.

OBJECTIVE

This study aims to evaluate booster engagement across booster delivery modalities (Web and Peer) and identify participant-specific factors associated with booster session engagement.

METHODS

Following a brief web-based alcohol misuse intervention in National Guard members (N=739), we examined engagement in a series of three booster sessions. Using unadjusted and adjusted models, demographic and clinical characteristics that may serve as predictors of booster session engagement were examined across the 2 arms of the trial with different types of booster sessions: peer-delivered (N=245) and web-delivered (N=246).

RESULTS

Booster session completion was greater for Peer than Web Booster sessions, with 142 (58%) service members in the Peer Booster arm completing all three boosters compared with only 108 (44%) of participants in the Web Booster arm (χ=10.3; P=.006). In a model in which the 2 groups were combined, socioeconomic factors predicted booster engagement. In separate models, the demographic and clinical predictors of booster engagement varied between the 2 delivery modalities.

CONCLUSIONS

The use of peer-delivered boosters, especially among subsets of reserve members at risk of lack of engagement, may foster greater uptake and improve treatment outcomes.

摘要

背景

酒精滥用是军人面临的主要健康问题。预备役军人面临着独特的障碍，因为他们住在基地外，获得行为健康服务的机会有限。基于网络和应用程序的简短干预是一种很有前景的方法，可以改善酗酒者获得治疗的机会，通过使用强化疗程来提高有效性、巩固成果和强化改变。然而，对于谁会参与强化疗程知之甚少。

目的

本研究旨在评估不同强化疗程交付方式（网络和同伴）下的强化疗程参与情况，并确定与强化疗程参与相关的参与者特定因素。

方法

在对国民警卫队成员（N = 739）进行基于网络的简短酒精滥用干预后，我们检查了一系列三个强化疗程的参与情况。使用未调整和调整后的模型，在试验的两个不同类型强化疗程的组中，研究了可能作为强化疗程参与预测因素的人口统计学和临床特征：同伴交付组（N = 245）和网络交付组（N = 246）。

结果

同伴强化疗程的完成率高于网络强化疗程，同伴强化疗程组中有142名（58%）军人完成了所有三个强化疗程，而网络强化疗程组中只有108名（44%）参与者完成（χ = 10.3；P = .006）。在将两组合并的模型中，社会经济因素预测了强化疗程的参与情况。在单独的模型中，两种交付方式下强化疗程参与的人口统计学和临床预测因素有所不同。
