Data gathered from 2 longitudinal studies (the Christchurch Health and Development study of a birth cohort of 1,265 New Zealand participants studied to 21 years and the Quebec Study of 240 Canadian participants studied to 13 years) was used to examine the linkages between deviant peer affiliations and depression in adolescence. Both studies produced similar conclusions: a) increasing peer affiliations were associated with significant (p < .0001) increases in depressive symptoms; b) the associations between peer affiliations and depression could not be fully explained by confounding factors; and c) peer affiliations and depressive symptoms were linked by a causal chain process in which deviant peer affiliations led to increased externalizing behaviors with the negative consequences of these behaviors leading to depression.
从两项纵向研究（对1265名新西兰参与者的出生队列进行的克赖斯特彻奇健康与发展研究，该队列研究至21岁；以及对240名加拿大参与者进行的魁北克研究，该队列研究至13岁）收集的数据用于检验青少年中不良同伴关系与抑郁之间的联系。两项研究都得出了类似的结论：a）同伴关系的增加与抑郁症状的显著增加（p <.0001）相关；b）同伴关系与抑郁之间的关联不能完全由混杂因素解释；c）同伴关系与抑郁症状通过因果链过程相联系，其中不良同伴关系导致外化行为增加，这些行为的负面后果导致抑郁。
