There is a growing body of evidence highlighting the presence of a single general dimension of psychopathology that can account for multiple associations across mental and substance use disorders. However, relatively little evidence has emerged regarding the validity of this model with respect to a range of factors that have been previously implicated across multiple disorders. The current study utilized a cross-sectional population survey of adolescents (n = 2,003) to examine the extent to which broad psychopathology factors account for specific associations between psychopathology and key validators: poor sleep, self-harm, suicidality, risky sexual behavior, and low self-esteem. Confirmatory factor models, latent class models, and factor mixture models were estimated to identify the best structure of psychopathology. Structural equation models were then estimated to examine the broad and specific associations between each psychopathology indicator and the validators. A confirmatory factor model with three lower-order factors, representing internalizing, externalizing, and psychotic-like experiences, and a single higher-order factor evidenced the best fit. The associations between manifest indicators of psychopathology and validators were largely nonspecific. However, significant and large direct effects were found between several pairwise associations. These findings have implications for the identification of potential targets for intervention and/or tailoring of prevention programs.
越来越多的证据强调,有一种单一的普遍精神病理学维度,可以解释多种精神和物质障碍之间的关联。然而,关于这一模型对于先前涉及多种疾病的一系列因素的有效性的证据相对较少。本研究利用青少年的横断面人群调查(n=2003),考察了广泛的精神病理学因素在多大程度上可以解释精神病理学与关键验证者之间的特定关联:睡眠质量差、自残、自杀意念、危险性行为和低自尊。使用验证性因子模型、潜在类别模型和因子混合模型来确定精神病理学的最佳结构。然后,使用结构方程模型来检验每个精神病理学指标与验证者之间的广泛和具体的关联。具有三个较低阶因素(代表内化、外化和精神病样体验)和一个单一的高阶因素的验证性因子模型具有最佳拟合度。精神病理学的明显指标与验证者之间的关联大多是非特异性的。然而,在几个成对关联之间发现了显著且较大的直接效应。这些发现对确定潜在的干预目标和/或调整预防计划具有重要意义。
