Differential Transdiagnostic Relevance of Early Maladaptive Schemas Across Personality Traits and Psychopathological Symptoms.

Abstract

The Alternative Model for Personality Disorders in DSM-5 conceptualizes personality pathology using dimensional trait domains, yet the cognitive mechanisms underlying these traits remain insufficiently understood. Early maladaptive schemas (EMSs) represent enduring cognitive-affective structures that may contribute to both personality pathology and general psychological distress. However, it remains unclear whether all schemas function as broadly transdiagnostic vulnerability factors or whether their relevance varies across symptom- and trait-based outcomes. In this study, we examined associations between 18 EMSs, DSM-5 pathological personality traits, and general psychopathological symptoms in a nonclinical sample (N = 489). Each schema was examined separately in regression analyses, and only associations with large standardized effects (|β| ≥ 0.50) were interpreted following Bonferroni correction. The results revealed substantial heterogeneity among EMSs. Rather than all schemas demonstrating comparable transdiagnostic relevance, only a limited subset showed strong associations across multiple outcome domains. Schemas characterized by heightened threat sensitivity and negative expectancy patterns (Vulnerability to Harm, Negativity/Pessimism) exhibited the broadest and most consistent associations with affective, anxiety-related, and psychoticism-related symptoms, as well as with Negative Affectivity at the trait level. In contrast, other schemas showed more circumscribed, domain-specific associations, mapping preferentially onto either symptom dimensions or personality trait domains. These findings indicate that EMSs differ meaningfully in the scope and strength of their associations with psychopathology. Rather than constituting a uniform transdiagnostic substrate, schemas appear to operate at different levels of the psychopathological hierarchy, with some functioning as broad cognitive-affective vulnerability factors and others reflecting more specific regulatory or interpersonal processes.
