Increasingly, three generation studies have investigated intergenerational (IG) continuity and discontinuity in substance use and related problem behaviors. However, surprisingly little attention has been paid to the conceptual definition of continuity or to different types of discontinuity (resilience and escalation) or to measurement sensitivity, which affects not only the magnitudes of observed continuity but also factors that correlate with this linkage. This study uses longitudinal data on 427 parent-child dyads from the Rochester IG Study to study continuity and discontinuity in substance use over ages 14-18. Results suggest that the degree of IG continuity, resilience, and escalation in adolescent substance use, as well as correlates of each, depend heavily on how heterogeneity in the behavior is taken into account.
越来越多的三代研究调查了代际（IG）在物质使用和相关问题行为方面的连续性和非连续性。然而，令人惊讶的是，很少有人关注连续性的概念定义，也很少关注不同类型的非连续性（弹性和升级）或测量灵敏度，这不仅影响观察到的连续性的大小，还影响与这种联系相关的因素。本研究使用罗切斯特 IG 研究中 427 对父母-子女对的纵向数据，研究了青少年时期物质使用的代际连续性和非连续性。研究结果表明，青少年物质使用中代际连续性、弹性和升级的程度，以及每种物质的相关性，在很大程度上取决于如何考虑行为的异质性。
