背景:确定临时(酒精)禁欲挑战(TAC)参与者的亚组可能为提高干预效果提供机会。然而,缺少有关此类子组的知识。这项研究旨在(i)描述TAC人群;(ii)根据饮酒行为变化的决定因素确定参与者的亚组;(iii)根据社会人口统计学和其他特征表征亚组。
方法:对来自3803名荷兰TAC参与者的数据进行分析,以使用三步潜在类别分析来识别亚组。课程基于饮酒行为变化的决定因素(即,拒绝饮酒的自我效能,渴望和行为自动性),并以社会人口统计学特征为特征,饮酒行为,以前参加过TAC,自我报告的健康和生活满意度。
结果:大多数TAC参与者是女性,受过高等教育,employed,平均53岁,参加了以前的TACs,并报告了相对较高的酒精使用率。确定了四类参与者:(i)“普通饮酒者”(49.0%);(ii)“控制中的饮酒者”(21.4%);(iii)“具有控制感的习惯性饮酒者拒绝”(18.4%);(iv)“不受控制的饮酒者”(11.2%)。2级饮酒最少且不过量,而其他班级通常每周喝4天或更长时间,每个饮酒日喝3至4杯,在第4类中发现的酒精使用量最高。
结论:本研究四个亚组中决定因素的不同配置可能需要不同的干预方法,并可能提供个性化支持。未来的研究需要检查这些亚组对挑战后饮酒行为的预测价值,以评估支持需求和参与价值。
BACKGROUND: Identifying subgroups of Temporary (alcohol) Abstinence Challenge (TAC) participants may offer opportunities to enhance intervention effectiveness. However, knowledge about such subgroups is missing. This study aimed to (i) describe a TAC population; (ii) identify subgroups of participants based on determinants of changes in drinking behaviour; and (iii) characterise subgroups in terms of sociodemographic and other characteristics.
METHODS: Data from 3803 Dutch TAC participants were analysed to identify subgroups using three-step Latent Class Analysis. Classes were based on determinants of changes in drinking behaviour (i.e., drinking refusal self-efficacy, craving and behavioural automaticity) and were characterised by sociodemographic characteristics, drinking behaviour, previous participation in TACs, self-reported health and life satisfaction.
RESULTS: The majority of TAC participants were female, highly educated, employed, 53 years old on average, participated in previous TACs and reported relatively high alcohol use. Four classes of participants were identified: (i) \'ordinary drinkers\' (49.0%); (ii) \'drinkers in control\' (21.4%); (iii) \'habitual drinkers with perceived control to refuse\' (18.4%); and (iv) \'drinkers not in control\' (11.2%). Class 2 drank least often and non-excessive volumes, while other classes typically drank 4 or more days per week and 3 to 4 glasses per drinking day, with the highest alcohol use found in class 4.
CONCLUSIONS: Different configurations of determinants in this study\'s four subgroups may require different intervention approaches and might inform personalised support. Future research is needed to examine the predictive value of these subgroups on post-challenge drinking behaviour to assess support needs and participation value.
