Growth of Forms and Functions of Aggression in Youth

描述（由申请人提供）：攻击性在概念上被区分为各种功能（例如，工具性与反应性）和形式（公开与关系性），但直到最近才发展出一种方法论和分析方法，充分解开攻击的这些组成部分。拟议的研究将通过从三个互补的方法纵向研究攻击的工具和反应功能（其次是显性和关系形式）来扩展这种方法：个体差异，个体内（即，成长轨迹，以人为本。与相关结构的关系（即，抑郁症，情绪失调，受害，和同伴拒绝）将被检查，并按性别，年级和种族的潜在适度也将被系统地探讨。

DESCRIPTION (provided by applicant): Aggression has been conceptually distinguished into various functions (e.g., instrumental versus reactive) and forms (overt versus relational), but only recently has a methodological and analytic approach been developed that adequately disentangles these components of aggression. The proposed research will extend this approach by examining instrumental and reactive functions (and secondarily, overt and relational forms) of aggression longitudinally from three complementary approaches: individual differences, intraindividual (i.e., growth) trajectories, and person-centered. Relations with relevant constructs (i.e., depression, emotional dysregulation, victimization, and peer rejection) will be examined, and potential moderation by gender, grade, and ethnicity will also be systematically explored.
