Personality traits and the reporting of affective disorder symptoms in depressed patients

Background er understanding of the influences on self-reported mood symptoms could inform the debate about the utility of self-report instruments and enhance the assessment and treatment of affective disorders. We tested the hypotheses that higher Neuroticism is associated with the over-reporting of affective symptoms and lower Openness to Experience is associated with the under-reporting of affective symptoms. s ts were 134 inpatients of ages 50 and over diagnosed with a mood disorder. Personality was assessed with the Revised NEO Personality Inventory. Self-reported depression was assessed with the Beck Depression Inventory-II; observer-rated depression was assessed via the Hamilton Depression Rating Scale. Symptom-reporting was defined as the ratio of self-reported to observer-rated symptoms. s othesized, multivariate linear regression analyses revealed that high Neuroticism contributed to patientsʹ over-reporting of mood symptoms. Contrary to the hypothesis, low Openness was associated with high ratios of self-reported to observer-rated mood symptoms. tions sectional design and unclear generalizability to racial/ethnic minorities. sions are important correlaters of self-reported vs. observer-rated symptoms in patients with affective disorders. To the extent that economic imperatives and other pressures impel greater reliance on self-report data in mental health research and services, there will be a corresponding need for prospective research on the determinants and clinical implications of discrepancies between self-reports and observer ratings.
