Neuroticism as an underlying construct in youth emotional disorders.

Structural research on neuroticism, as indicated by Big Five personality traits and/or internalizing symptoms, has been conducted with youth. However, no structural research has investigated neuroticism as characterized by transdiagnostic risk factors such as distress tolerance (DT), negative affect (NA), and avoidance. No study has investigated whether DT, NA, and avoidance, as a group, are associated with anxiety, depressive, obsessive-compulsive (OC) symptoms, and independent evaluator (lE)-rated symptom severity in a clinical sample of youth. The purpose of the current investigation was to understand the proportion of variance in anxiety, depressive, OC symptoms, and independent evaluator-rated global symptom severity by a latent construct of neuroticism, as indicated by these modifiable features in youth with emotional disorders among a sample of 121 adolescents (ages 13-18, 51.2% female). A latent neuroticism factor was significantly associated with greater youth- and parent-reported anxiety, depressive, and OC symptoms, and greater IE-rated global severity.
