Abstract

Background

Personality is associated with self-rated health, but prior studies have not examined associations with preference-based measures. We hypothesized similar associations would exist with preference-based health.

Methods

We analyzed baseline data from chronically ill individuals enrolled in a self-management intervention. We conducted regression analyses with the EQ-5D summary index score and dimension scores (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) as dependent variables, The key independent variables were NEO-Five Factor Inventory (NEO-FFI) personality factors (Neuroticism, Conscientiousness, Extraversion, Openness, Agreeableness), adjusting for age, gender, educational level, minority status, and chronic conditions.

Results

Of 415 participants, 245 (59%) had ≥2 chronic conditions, 384 (94%) completed the NEO-FFI and 397 (96%) the EQ-5D. After adjustment, Neuroticism was associated with EQ-5D summary index scores [−0.04 per 1 SD increase in Neuroticism (95% CI −0.06, −0.01)]. Neuroticism [AOR 2.99 (95% CI 2.06, 4.35; P < 0.001)] and Openness [1.32 (95% CI 1.00, 1.75; P = 0.05)] were associated with worse anxiety/depression scores, while Conscientiousness was associated with better usual activities scores [0.66 (95% CI 0.49, 0.89; P = 0.01)].

Conclusions

The associations between personality factors and self-rated health appear to extend to preference-based measures. Future studies should explore whether personality affects preference-based health estimates in cost-effectiveness analyses.
