Abstract

Background and Aims

ABC-training is a new intervention to encourage health behavior change that targets the automatic activation of adaptive beliefs (i.e. automatic inferences). The aim of this proof-of-principle study was to test the effectiveness of web-based ABC-training to change outcome expectancies of alcohol drinking in a sample of hazardous drinkers.

Design

One exploratory and one confirmatory experiment with two between-subject conditions (online ABC- and control-training) and assessments at baseline and 1 week later (after three sessions of training).

Setting

Participants recruited on Prolific Academic completed the web-based study.

Participants

Adults with self-reported hazardous alcohol drinking (Experiment 1: 193 adults, United Kingdom, age mean = 46.7 years; Experiment 2: 282 adults, different nationalities, age mean = 38.3 years).

Intervention and Comparator

ABC-training involved completing an online task that required choosing personally relevant alternative behaviors to drinking alcohol in personally relevant antecedent contexts to attain personally important outcomes. Comparator was control-training, in which participants selected both the alternative behaviors and alcohol drinking an equal number of times. Training was completed at baseline, after 3 days and after 1 week.

Measurements

Primary outcome was change in automatic and self-reported (negative/positive) outcome expectancies of alcohol drinking from baseline to after 1 week. Secondary outcomes were change in weekly alcohol consumption, self-efficacy, craving and motivation (and approach-alcohol associations in Experiment 1). Moderators were baseline outcome scores, motivation, age and alcohol dependency.

Findings

Findings of this study are as follows: stronger increase in negative outcome expectancies after ABC- than control-training (Experiment 1: self-report, 95% confidence interval of difference scores (CI_diff) = [0.04, Inf]; automatic, CI_diff = [0.01, Inf]; Experiment 2: self-report, CI_diff = [0.16, Inf]; automatic, CI_diff = [0.002, Inf]). Stronger reduction in self-reported positive outcome expectancies after ABC- than control-training (Experiment 1: CI_diff = [−Inf, −0.01]; Experiment 2: CI_diff = [−Inf, −0.21]) but mixed findings on automatic positive outcome expectancies (Experiment 1: CI_diff = [−Inf, 0.02]; Experiment 2: CI_diff = [−Inf, −0.001]).

Conclusions

ABC-training may change outcome expectancies of alcohol consumption, but testing of clinically relevant effects in other samples is warranted.

ABC训练作为危险饮酒的一种新干预措施：两项原理验证随机试验研究

背景和目的ABC训练是一种鼓励健康行为改变的新干预措施，其目标是自动激活适应性信念（即自动推断）。这项原理验证研究的目的是测试基于网络的ABC培训在危险饮酒者样本中改变饮酒预期结果的有效性。设计一个探索性和一个验证性实验，两个受试者之间的条件（在线ABC和对照训练）和基线评估和1 一周后（经过三次训练）。设置Prolific Academic上招募的参与者完成了基于网络的研究。参与者自我报告有危险饮酒的成年人（实验1:193名成年人，英国，年龄平均值=46.7 年；实验2:282名不同国籍的成年人，平均年龄=38.3 年）。干预和Comparator ABC培训涉及完成一项在线任务，该任务要求在与个人相关的先前环境中选择与个人有关的饮酒替代行为，以获得对个人重要的结果。比较者是对照训练，参与者选择替代行为和饮酒次数相等。培训在基线时完成，3 天及之后1 周测量主要结果是从基线到1年后饮酒的自动和自我报告（阴性/阳性）结果预期的变化周次要结果是每周饮酒量、自我效能、渴望和动机的变化（以及实验1中的酒精相关性）。调节因素是基线结果得分、动机、年龄和酒精依赖性。研究结果本研究的结果如下：ABC训练后阴性结果预期的增加比对照训练更强（实验1：自我报告，差异得分的95%置信区间（CIdiff） = [0.04，Inf]；自动，CIdiff = [0.01，Inf]；实验2：自我报告，CIdiff = [0.16，Inf]；自动，CIdiff = [0.002，Inf]）。与对照组训练相比，ABC训练后自我报告的阳性结果预期下降幅度更大（实验1:CIdiff = [−Inf，−0.01]；实验2：CIdiff = [−Inf，−0.21]），但对自动阳性结果预期的研究结果喜忧参半（实验1:CIdiff = [-Inf，0.02]；实验2：CIdiff = [−Inf，−0.001]）。结论ABC训练可能会改变饮酒的预期结果，但有必要在其他样本中测试临床相关效果。

期刊介绍： Addiction publishes peer-reviewed research reports on pharmacological and behavioural addictions, bringing together research conducted within many different disciplines. Its goal is to serve international and interdisciplinary scientific and clinical communication, to strengthen links between science and policy, and to stimulate and enhance the quality of debate. We seek submissions that are not only technically competent but are also original and contain information or ideas of fresh interest to our international readership. We seek to serve low- and middle-income (LAMI) countries as well as more economically developed countries. Addiction’s scope spans human experimental, epidemiological, social science, historical, clinical and policy research relating to addiction, primarily but not exclusively in the areas of psychoactive substance use and/or gambling. In addition to original research, the journal features editorials, commentaries, reviews, letters, and book reviews.
