Associations between personality traits and depressive and anxiety symptoms among persons with spinal cord injury in first inpatient rehabilitation

Abstract

Study design: Retrospective analysis of medical records. Objective: To assess personality traits in persons with spinal cord injury (SCI) and compare these with the general population group. Moreover, to explore associations between personality traits and depressive and anxiety symptoms among persons with SCI in first inpatient rehabilitation. Setting: Specialized rehabilitation center in The Netherlands. Methods: Data were used from a routine psychological screening, administered in the first weeks of admission (N = 67). Measures included the Hospital Anxiety and Depression Scale and the Dutch Personality Questionnaire, which includes subscales measuring neuroticism, social inadequacy, rigidity, hostility, egoism, dominance, and self-esteem. Correlational and regression analyses were conducted. Results: Mean age of the participants was 58 (SD 17) years. The majority (63%) were male, and had a low lesion (57%). The participants scored significantly higher on dominance and lower on social inadequacy, hostility, and egoism in comparison with the general population. In the bivariate regression analyses, high neuroticism (β = 0.42 and β = 0.53) and low self-esteem (β = -0.25 and β = -0.29) were significantly associated with increased depressive and anxiety symptoms. In the hierarchical regression analyses, only high neuroticism was significantly associated with increased depressive (β = 0.42, p < 0.05) and anxiety (β = 0.55, p < 0.001) symptoms. Conclusions: Personality traits are not the same between the SCI population and the general population. Assessment of personality traits early in inpatient rehabilitation can help to identify individuals at risk of mood problems and, thereby, facilitate interventions. Future research with a larger, representative SCI sample, is required to confirm these findings.
