Reciprocal effects of personality and general distress: Neuroticism vulnerability is stronger than scarring.

Abstract

Internalizing (anxiety and depressive) disorders, and the symptoms that comprise them, are known for being chronic and recurrent. Neuroticism, reflecting dispositional tendencies toward negative affect, is a personality trait that bears durable cross-sectional and prospective associations with internalizing symptoms. There are also indications that extraversion, consisting of tendencies such as the heightened experience of positive emotion, is associated with these symptoms. Some investigators have posited that the experience of internalizing symptoms leaves residual effects, or scars, on personality traits, with the effect of raising risk of symptom reexacerbation. In the present study, we compare vulnerability and scar effects in a sample of older adolescents (N = 606) at risk for the development of internalizing disorders. Anxiety and depressive symptoms were assessed annually, as were neuroticism, extraversion, and other trait-like cognitive vulnerabilities. Cross-lagged panel models compared the relative strength of vulnerability and scar effects, revealing support for vulnerability effects but little evidence of scar effects. The results also showed that whatever scar effects might be present are weaker than vulnerability effects in the case of neuroticism. These findings underscore the importance of personality vulnerability for internalizing symptom risk by suggesting that neuroticism vulnerability is stronger than any lasting scars the experience of internalizing symptoms produce.
