There is ongoing debate regarding whether psychopathy dimensions (i.e., narcissism, callous-unemotional [CU] traits, and impulsivity) can be meaningfully identified among youth samples and the correlates of these components. Thus, the present study conducted confirmatory factor analyses of the parent-reported Antisocial Process Screening Device (APSD; Frick and Hare 2001) among early adolescents, and examined whether trajectories of conduct problems (CP) through childhood were associated with APSD total and subscale scores. Participants included the normative and high-risk control samples from the Fast Track project (N = 754, male = 58%, Black = 46%). Parents reported on CP in kindergarten, grades 1, 2, 4, 5, and 7, and psychopathy in grade 7. Factor analyses supported the three-factor structure. Latent class growth analyses identified four trajectories of CP including extremely high increasing (3.6%), high stable (21.6%), moderate decreasing (38.7%), and low decreasing (36.1%). All CP trajectories were significantly different from each other on psychopathy total, narcissism, and impulsivity scores; the extremely high increasing and high stable trajectories did not differ from each other on CU traits, but they scored significantly higher than the moderate decreasing and low decreasing trajectories. When controlling for other dimensions, all trajectories were significantly different on narcissism. The extremely high increasing and high stable CP trajectories did not differ from each other on impulsivity, but they scored higher than the moderate decreasing and low trajectories. Only the extremely high increasing and high stable trajectories scored higher than the low decreasing trajectory on CU traits.

关于是否可以在青年样本中以及这些成分的相关性方面有意义地确定心理疾病的维度（即自恋，无情的[CU]性格和冲动性），目前仍存在争议。因此，本研究对青少年早期父母报告的反社会过程筛查设备（APSD； Frick和Hare 2001）进行了验证性因素分析，并研究了儿童时期的行为问题轨迹（CP）是否与APSD总分和分量表得分相关。参与者包括来自快速通道项目的规范性和高风险控制样本（N = 754，男性= 58％，黑人= 46％）。家长报告了幼儿园的CP，1、2、4、5和7年级，以及7年级的精神病。因子分析支持三因子结构。潜在类增长分析确定了CP的四个轨迹，包括极高的增长（3.6％），高稳定（21.6％），中度下降（38.7％）和低下降（36.1％）。在心理总分，自恋和冲动得分上，所有CP轨迹均存在显着差异。在CU的性状上，极高的增长轨迹和高稳定的轨迹并没有什么不同，但是它们的得分明显高于中度下降和低下降的轨迹。当控制其他维度时，自恋的所有轨迹都明显不同。极高的增长和高稳定的CP轨迹在冲动方面没有区别，但它们的得分高于中等下降和低的轨迹。就CU性状而言，只有极高的增长轨迹和高稳定的轨迹得分高于低的下降轨迹。
