Common emotional and behavioral symptoms co-occur and are associated with core temperament factors. This study investigated links between temperament and dimensional, latent psychopathology factors, including a general common psychopathology factor (p factor) and specific latent internalizing and externalizing liabilities, as captured by a bifactor model, in two independent samples of youth. Specifically, we tested the hypothesis that temperament factors of negative affectivity (NA), positive affectivity (PA), and effortful control (EC) could serve as both transdiagnostic and specific risks in relation to recent bifactor models of child psychopathology. Sample 1 included 571 youth (average age 13.6, SD =2.37, range 9.3-17.5) with both youth and parent report. Sample 2 included 554 preadolescent children (average age 7.7, SD =1.35, range =5-11 years) with parent report. Structural equation modeling showed that the latent bifactor models fit in both samples. Replicated in both samples, the p factor was associated with lower EC and higher NA (transdiagnostic risks). Several specific risks replicated in both samples after controlling for co-occurring symptoms via the p factor: internalizing was associated with higher NA and lower PA, lower EC related to externalizing problems.
常见的情绪和行为症状同时出现，并与核心气质因素相关。本研究在两个独立的青少年样本中，调查了气质与维度性潜在精神病理学因素之间的联系，这些因素包括一个一般共同精神病理学因素（p因素）以及由双因素模型所捕捉的特定潜在内化和外化倾向。具体而言，我们检验了以下假设：消极情感性（NA）、积极情感性（PA）和努力控制（EC）这些气质因素，相对于儿童精神病理学的近期双因素模型，既可以作为跨诊断风险，也可以作为特定风险。样本1包括571名青少年（平均年龄13.6岁，标准差=2.37，范围9.3 - 17.5岁），既有青少年的报告，也有家长的报告。样本2包括554名青春期前儿童（平均年龄7.7岁，标准差=1.35，范围5 - 11岁），只有家长的报告。结构方程模型表明，潜在双因素模型在两个样本中均拟合良好。在两个样本中均得到重复验证的是，p因素与较低的EC和较高的NA相关（跨诊断风险）。在通过p因素控制共发症状后，几个特定风险在两个样本中也得到了重复验证：内化与较高的NA和较低的PA相关，较低的EC与外化问题相关。
