摘要

这项调查回答并扩大了对早期青少年临床样本中精神病理学的跨诊断结构建模的呼吁,并使用严格的心理测量标准。在162名11-13岁的儿童中,我们比较了包含潜在内化因素和外化因素的相关双因素模型和添加了跨诊断一般因素的双因素模型。我们还从心理测量学上评估了双因素模型,包括社会心理功能广泛指标的标准效度。在此过程中,我们比较了定义和解释标准有效性的不同方法:最近提出的基于解释的标准因素方差的增量定义,以及基于概念上有意义的关系的更典型的定义。虽然传统的拟合统计如预期的那样倾向于双因素模型,但心理测量分析增加了重要的细微差别。尽管有中等的可靠性,但一般因素并不是完全跨诊断的(即,没有被几个外化分数告知),并且与内化分数部分冗余。对标准效度的研究得出了相反的结果。与相关的双因素模型相比,双因素模型重新分配了社会心理功能标准指标解释的总方差,而不是增量增加。然而,双因素模型确实提高了临床上重要的社会心理功能关系的准确性,这就提出了关于双因素精神病理学模型的有意义测试的问题。

The Structure of Psychopathology in a Sample of Clinically Referred, Emotionally Dysregulated Early Adolescents.

This investigation answers and amplifies calls to model the transdiagnostic structure of psychopathology in clinical samples of early adolescents and using stringent psychometric criteria. In 162 clinically referred, clinically evaluated 11-13-year-olds, we compared a correlated two-factor model, containing latent internalizing and externalizing factors, to a bifactor model, which added a transdiagnostic general factor. We also evaluated the bifactor model psychometrically, including criterion validity with broad indicators of psychosocial functioning. In doing so, we compared alternative approaches to defining and interpreting criterion validity: a recently proposed incremental definition based on amounts of variance in criterion factors explained, and the more typical definition based on the presence of conceptually meaningful relationships. While traditional fit statistics favored the bifactor model as expected, psychometric analyses added important nuance. Despite moderate reliability, the general factor was not fully transdiagnostic (i.e., was not informed by several externalizing scores), and was partially redundant with internalizing scores. Approaches to criterion validity yielded opposing results. Compared to the correlated two-factor model, the bifactor model redistributed, without incrementally increasing, the total variance explained in criterion indicators of psychosocial functioning. Yet, the bifactor model did improve the precision of clinically important relationships to psychosocial functioning, raising questions about meaningful tests of bifactor psychopathology models.

期刊介绍: Research on Child and Adolescent Psychopathology brings together the latest innovative research that advances knowledge of psychopathology from infancy through adolescence. The journal publishes studies that have a strong theoretical framework and use a diversity of methods, with an emphasis on empirical studies of the major forms of psychopathology found in childhood disorders (e.g., disruptive behavior disorders, depression, anxiety, and autism spectrum disorder). Studies focus on the epidemiology, etiology, assessment, treatment, prognosis, and developmental course of these forms of psychopathology. Studies highlighting risk and protective factors; the ecology and correlates of children''s emotional, social, and behavior problems; and advances in prevention and treatment are featured. Research on Child and Adolescent Psychopathology is the official journal of the International Society for Research in Child and Adolescent Psychopathology (ISRCAP), a multidisciplinary scientific society.
