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（显性与关系性），但直到最近才开发出一种方法和分析方法来充分地解开这些攻击性的组成部分。本研究将扩展这一方法，从三个互补的角度纵向考察攻击性的工具性和反应性功能（其次是显性和相关形式）：个体差异、个体内部（即成长）轨迹和以人为中心。与相关构念（即抑郁、情绪失调、受害和同伴排斥）的关系将被检查，性别、年级和种族的潜在调节也将被系统地探索。

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.
