压力产生假说最初是为了理解抑郁症的复发而制定的，最近已被应用于焦虑和外化障碍的研究。这些调查的结果，结合抑郁症和其他精神疾病之间的广泛的共病性的发现，建议需要扩大的压力产生模型，包括跨诊断病理学的压力产生的影响，以及那些特定的综合征。采用潜变量建模技术来解析共同发生的轴I综合征的一般和特定元素，目前的研究探讨了transdiagnosis内化和外化维度随着时间的推移与压力生活事件的关联。分析表明，调整后的尺寸之间的协变，内化是一个显着的预测人际依赖的压力，而外化是一个显着的预测非人际依赖的压力。两个潜在维度都与独立的或决定性的压力性生活事件的发生无关。在综合征水平上，一旦由于内化因素而产生的差异被排除，单极抑郁症就会逐渐导致人际依赖性压力的产生。相比之下，恐慌症的存在产生了“压力抑制”效应，预测减少暴露于人际依赖压力。此外，心境恶劣与过度的非人际依赖压力有关。潜变量建模框架在这里使用的讨论，其潜力作为一个综合模型的压力产生的研究。
Originally formulated to understand the recurrence of depressive disorders, the stress generation hypothesis has recently been applied in research on anxiety and externalizing disorders. Results from these investigations, in combination with findings of extensive comorbidity between depression and other mental disorders, suggest the need for an expansion of stress generation models to include the stress generating effects of transdiagnostic pathology as well as those of specific syndromes. Employing latent variable modeling techniques to parse the general and specific elements of commonly co-occurring Axis I syndromes, the current study examined the associations of transdiagnostic internalizing and externalizing dimensions with stressful life events over time. Analyses revealed that, after adjusting for the covariation between the dimensions, internalizing was a significant predictor of interpersonal dependent stress, whereas externalizing was a significant predictor of noninterpersonal dependent stress. Neither latent dimension was associated with the occurrence of independent, or fateful, stressful life events. At the syndrome level, once variance due to the internalizing factor was partialled out, unipolar depression contributed incrementally to the generation of interpersonal dependent stress. In contrast, the presence of panic disorder produced a “stress inhibition” effect, predicting reduced exposure to interpersonal dependent stress. Additionally, dysthymia was associated with an excess of noninterpersonal dependent stress. The latent variable modeling framework used here is discussed in terms of its potential as an integrative model for stress generation research.
