Multiple group latent curve analysis was used to assess the impact of changes in marital status on alcohol use trajectories in young adults and to test if these effects varied across ethnicity and gender.
Four years of data were obtained from a sample of young adults (N = 4,052; 54% male) drawn from the National Longitudinal Survey of Youth. Alcohol use and marital status were assessed once per year and covariates included age, gender, education and ethnicity.
Latent curve models indicated that there was an overall nonlinear negative alcohol use trajectory across the four time points and that becoming married was reliably associated with an added down-turn to this trajectory. Multiple group models indicated that there was an interaction between ethnicity and marital status in the prediction of alcohol growth trajectories, but there was no interaction with gender.
Becoming married for the first time exerted a unique effect on the overall developmental trajectory of alcohol use over time. This effect held for both ethnic groups but was reliably stronger for white compared to black respondents. This interaction may be attributable to lower levels of alcohol use reported by black respondents, or may be related to individual differences in reactivity to social influences by blacks relative to whites.
采用多组潜在曲线分析来评估婚姻状况变化对年轻人饮酒轨迹的影响，并检验这些影响在不同种族和性别之间是否存在差异。
从全国青年纵向调查中抽取的年轻人样本（N = 4,052；54%为男性）获取了四年的数据。每年评估一次饮酒情况和婚姻状况，协变量包括年龄、性别、教育程度和种族。
潜在曲线模型表明，在四个时间点上存在总体非线性的负饮酒轨迹，并且结婚与该轨迹的额外下降可靠相关。多组模型表明，在预测酒精增长轨迹时，种族和婚姻状况之间存在交互作用，但与性别不存在交互作用。
初婚对饮酒随时间的总体发展轨迹产生了独特影响。这种影响在两个种族群体中都存在，但与黑人受访者相比，白人的这种影响更显著。这种交互作用可能归因于黑人受访者报告的饮酒水平较低，或者可能与黑人相对于白人对社会影响的反应性个体差异有关。
