There is increasing evidence for multiple pathways in the development of callous-unemotional (CU) features, including primary and secondary profiles. Understanding affect regulation strategies among variants may provide further insight to the development and treatment of CU features. This study evaluated whether profiles of CU features could be identified within a clinical sample of youth using measures of affect dysregulation, affect suppression, anxiety, and maltreatment. We also examined whether these profiles were consistent across gender. Participants (N = 418; 56.7% female) ranged in age from 12 to 19 years (M = 15.04, SD = 1.85) and were drawn from a clinical sample. Latent profile analysis (LPA) was conducted using five indicators, including affect regulation, suppression, anxiety, CU features, and maltreatment. The best fitting model, a four-profile solution, included a low (low CU/dysregulation), anxious (low CU/high dysregulation), primary CU (high CU/low dysregulation), and secondary CU profile (high CU/dysregulation/maltreatment). LPAs found the same four-profile model when conducted separately for males and females. This is the first study to examine gender and include affect regulation strategies in the examination of primary and secondary profiles of CU.
越来越多的证据表明，冷酷无情（CU）特征的发展存在多种途径，包括主要和次要特征。了解不同变体的情感调节策略可能为 CU 特征的发展和治疗提供进一步的见解。本研究使用情感失调、情感抑制、焦虑和虐待的衡量标准，评估了在青少年临床样本中是否可以识别出 CU 特征的特征。我们还检查了这些特征是否在性别上一致。参与者（N=418；56.7%为女性）年龄在 12 至 19 岁之间（M=15.04，SD=1.85），来自临床样本。使用五个指标（包括情感调节、抑制、焦虑、CU 特征和虐待）进行潜在剖面分析（LPA）。最佳拟合模型是一个四特征模型，包括低 CU/失调特征（低 CU/失调）、焦虑特征（低 CU/高失调）、主要 CU 特征（高 CU/低失调）和次要 CU 特征（高 CU/失调/虐待）。当分别对男性和女性进行 LPAs 时，发现了相同的四特征模型。这是第一个研究性别并在 CU 的主要和次要特征检查中包含情感调节策略的研究。
