In the present study, we examined whether we could replicate previous findings that use of protective behavioral strategies (PBSs) mediates the associations between distal antecedents and alcohol-related outcomes in an independent sample. Further, we examined a more comprehensive model to determine which constructs uniquely (i.e., controlling for other distal antecedents) relate to PBS use and alcohol-related outcomes.
Participants were recruited from a psychology department participant pool at a large, southwestern university in the United States (N = 628). The majority of participants identified themselves as being either Hispanic (n = 334, 53.18%) or White, non-Hispanic (n = 212, 33.78%), were female (n = 386, 61.5%), and reported a mean age of 20.30 (SD = 3.80) years.
Across five replication attempts in separate models, we found significant indirect associations of age at first use, self-regulation, impulsivity-like traits, depressive symptoms, and conscientiousness on alcohol-related outcomes (i.e., use and problems) via PBS use. However, only the indirect associations of a second-order latent factor of self-regulation (based on premeditation, perseverance, self-regulation, and conscientiousness) and age at first use on alcohol-related outcomes via PBS use remained significant in the comprehensive model.
Taken together, the replication attempts were largely successful in that nearly all associations were replicated in an independent sample of college students. However, in a comprehensive model with all distal antecedents simultaneously included, most of the direct and indirect associations failed to be supported.
在本研究中,我们检验了是否能够在一个独立样本中复制先前的研究结果,即使用保护性行为策略(PBSs)在远端前因与酒精相关结果之间的关联中起中介作用。此外,我们检验了一个更全面的模型,以确定哪些构念(即控制其他远端前因)与PBSs的使用以及酒精相关结果有独特关联。
参与者从美国西南部一所大型大学的心理学系参与者库中招募(N = 628)。大多数参与者表明自己是西班牙裔(n = 334,53.18%)或非西班牙裔白人(n = 212,33.78%),女性(n = 386,61.5%),报告的平均年龄为20.30岁(标准差 = 3.80)。
在单独模型中的五次重复尝试中,我们发现首次使用年龄、自我调节、冲动样特质、抑郁症状和尽责性通过PBSs的使用与酒精相关结果(即使用和问题)存在显著的间接关联。然而,在综合模型中,只有自我调节的二阶潜在因子(基于预谋、毅力、自我调节和尽责性)和首次使用年龄通过PBSs的使用与酒精相关结果的间接关联仍然显著。
总体而言,重复尝试在很大程度上是成功的,因为几乎所有关联都在一个独立的大学生样本中得到了复制。然而,在同时纳入所有远端前因的综合模型中,大多数直接和间接关联均未得到支持。
