Abstract

Background: The popularity of temporary abstinence challenges (TACs) concerning alcohol consumption is increasing. Support is found to be essential for participants to help them get through a challenge. This study aimed to evaluate the additional effect of a self-help guide, based on health behaviour theories and behaviour change techniques, on (i) successful completion of a TAC and (ii) changes in drinking refusal self-efficacy (DRSE), behavioural automaticity, craving, and alcohol consumption.

Methods: A randomized controlled trial was performed (OSF registries: OSF.IO/B95VU). NoThanks participants received a questionnaire before the TAC (T0) and 8 months after the TAC (T1). Out of a subgroup of 1308 respondents who were interested in additional support, 652 were randomly assigned to receive the guide (experimental group), and 656 did not receive any additional support (control group). Logistic regressions and (generalized) linear mixed model analyses were used.

Results: After 8 months, all participants showed a significant decrease in behavioural automaticity, craving, and alcohol consumption, irrespective of group assignment. No significant changes were observed in the DRSE. This degree of change over time in behavioural automaticity, craving, and alcohol consumption did not differ between the experimental and control group. Sensitivity analyses with participants in the experimental group, who differed in exposure to the guide, did not show differences either.

Conclusion: The self-help guide, and how it was designed, added no value to the TAC. Future research should focus on more bottom-up, customized support and explore what (different subgroups of) participants think they need as extra support during a TAC.

临时戒酒挑战期间自助指南的有效性:随机对照试验。
背景:有关酒精消费的临时戒酒挑战(TACs)越来越受欢迎。研究发现,对参与者的支持对帮助他们度过挑战至关重要。本研究旨在评估基于健康行为理论和行为改变技术的自助指南对(i)成功完成临时戒酒挑战和(ii)拒绝饮酒自我效能感(DRSE)、行为自动性、渴望和饮酒量变化的额外影响:进行了一项随机对照试验(OSF 登记:OSF.IO/B95VU)。NoThanks参与者在TAC前(T0)和TAC后8个月(T1)接受了问卷调查。在对额外支持感兴趣的 1308 名受访者中,有 652 人被随机分配接受指南(实验组),656 人未接受任何额外支持(对照组)。研究采用了逻辑回归和(广义)线性混合模型分析:8 个月后,所有参与者的行为自动性、渴求和饮酒量都有显著下降,与分组无关。在 DRSE 中没有观察到明显的变化。随着时间的推移,实验组和对照组在行为自动性、渴求和饮酒量方面的变化程度没有差异。对实验组参与者进行的敏感性分析也未显示出差异:结论:自助指南及其设计方式没有为 TAC 带来任何价值。未来的研究应关注更多自下而上的定制化支持,并探索(不同亚群的)参与者认为他们在 TAC 期间需要哪些额外支持。

期刊介绍: About the Journal Alcohol and Alcoholism publishes papers on the biomedical, psychological, and sociological aspects of alcoholism and alcohol research, provided that they make a new and significant contribution to knowledge in the field. Papers include new results obtained experimentally, descriptions of new experimental (including clinical) methods of importance to the field of alcohol research and treatment, or new interpretations of existing results. Theoretical contributions are considered equally with papers dealing with experimental work provided that such theoretical contributions are not of a largely speculative or philosophical nature.
