An examination of content overlap and disorder-specific predictions in the associations of neuroticism with anxiety and depression

This study examines whether content overlap artificially inflates estimates of the associations of emotional disorders with neuroticism and whether disorder-specificity of prediction exists. We demonstrated a statistical approach for testing the validity of hypothesized facets of neuroticism. In a sample of 627 adolescents, we indentified six facets of neuroticism, one intermediate facet, and a general neuroticism factor (GNF). Only the GNF and the depression facet were significantly associated with depressive symptomatology. The GNF and all facets significantly predicted anxiety symptomatology. This study offers a new statistical approach for addressing content overlap, testing for disorder-specific prediction and identifying facets of a broad personality trait, while indicating that content overlap does not largely explain the associations of neuroticism with psychopathology.
