The objective of the current study was to examine the possible temporal associations between alcohol misuse and problem gambling symptomatology from adolescence through to young adulthood. Parallel-process latent growth curve modeling was used to examine the trajectories of alcohol misuse and symptoms of problem gambling over time. Data were from a sample of adolescents recruited for the Leisure, Lifestyle, and Lifecycle Project in Alberta, Canada (n = 436), which included 4 assessments over 5 years. There was an average decline in problem gambling symptoms followed by an accelerating upward trend as the sample reached the legal age to gamble. There was significant variation in the rate of change in problem gambling symptoms over time; not all respondents followed the same trajectory. There was an average increase in alcohol misuse over time, with significant variability in baseline levels of use and the rate of change over time. The unconditional parallel process model indicated that higher baseline levels of alcohol misuse were associated with higher baseline levels of problem gambling symptoms. In addition, higher baseline levels of alcohol misuse were associated with steeper declines in problem gambling symptoms over time. However, these between-process correlations did not retain significance when covariates were added to the model, indicating that one behavior was not a risk factor for the other. The lack of mutual influence in the problem gambling symptomatology and alcohol misuse processes suggest that there are common risk factors underlying these two behaviors, supporting the notion of a syndrome model of addiction.

本研究的目的是探讨从青春期到青年期酒精滥用与问题赌博症状之间可能存在的时间关联。采用并行过程潜在增长曲线模型来检验酒精滥用和问题赌博症状随时间的轨迹。数据来自加拿大艾伯塔省休闲、生活方式和生命周期项目招募的青少年样本（n = 436），该项目在5年期间进行了4次评估。问题赌博症状平均呈下降趋势，随后随着样本达到法定赌博年龄，出现加速上升趋势。问题赌博症状随时间的变化率存在显著差异；并非所有受访者都遵循相同的轨迹。随着时间的推移，酒精滥用平均有所增加，使用的基线水平和随时间的变化率存在显著差异。无条件并行过程模型表明，较高的酒精滥用基线水平与较高的问题赌博症状基线水平相关。此外，较高的酒精滥用基线水平与问题赌博症状随时间更陡峭的下降相关。然而，当将协变量添加到模型中时，这些过程间的相关性不再显著，表明一种行为不是另一种行为的风险因素。问题赌博症状和酒精滥用过程中缺乏相互影响表明，这两种行为存在共同的风险因素，支持成瘾综合征模型的观点。（PsycINFO数据库记录）
