The research literature shows that discrepancies in positive parenting between parent and adolescent represents maladaptive parent-adolescent relationships, which are in turn positively linked to later substance use in Hispanic youth. However, questions remain about for whom interventions work and by what mechanisms they work to prevent discrepancies in positive parenting. The current study investigated the moderating and mediating roles of positive parenting discrepancy trajectories on the association between condition effect (i.e., a family-based intervention vs. prevention as usual condition) and substance use among Hispanic youth.
Eigth grade Hispanic adolescents (mean age = 13.86) and their primary caregivers (mean age = 42.32) were randomly assigned to two conditions: Familias Unidas (n = 376) or prevention as usual (n = 370). Participants were assessed at baseline and at 6, 18, and 30 months postbaseline. Using structural equation modeling, moderated mediation analyses were conducted to test whether the relationship between condition and past 90-day substance use at 30 months was mediated by discrepancy trajectories in positive parenting and whether direct and indirect relationships between condition and substance use were moderated by positive parenting discrepancies at baseline.
The results showed that, relative to prevention as usual, Familias Unidas reduced positive parenting discrepancies across time, when parent reports were higher than adolescent reports at baseline; this in turn, predicted substance use at 30 months postbaseline.
The findings provide important evidence supporting the need to collect multiple informant reports on positive parenting and examining the directionality of these reports among Hispanic families.
研究文献表明，父母与青少年之间积极养育方式的差异代表了适应不良的亲子关系，而这种关系又与西班牙裔青少年日后的物质使用呈正相关。然而，对于干预措施对哪些人有效，以及它们通过什么机制来预防积极养育方式的差异，仍存在一些问题。本研究调查了积极养育差异轨迹在条件效应（即家庭为基础的干预与常规预防条件）与西班牙裔青少年物质使用之间的关联中的调节和中介作用。
八年级西班牙裔青少年（平均年龄为 13.86 岁）及其主要照顾者（平均年龄为 42.32 岁）被随机分配到两个条件组：Familias Unidas（n=376）或常规预防组（n=370）。参与者在基线和 6、18 和 30 个月后进行评估。采用结构方程模型，进行调节中介分析，以检验条件与 30 个月时过去 90 天物质使用之间的关系是否通过积极养育差异轨迹来中介，以及条件与物质使用之间的直接和间接关系是否通过基线时的积极养育差异来调节。
结果表明，与常规预防组相比，Familias Unidas 减少了积极养育差异随时间的变化，当基线时父母报告高于青少年报告时；这反过来又预测了基线后 30 个月的物质使用。
这些发现为需要收集西班牙裔家庭中关于积极养育的多信息报告，并检验这些报告的方向性提供了重要证据。
