Abstract
ObjectiveTo explore whether patients with blepharospasm (BSP) have abnormal personality traits by the Minnesota Multiphasic Personality Inventory (MMPI) questionnaire. MethodThe personality profiles of patients with BSP and its relationship with clinical characteristics were assessed in this research. 46 patients with BSP and 33 age-and-gender matched healthy controls were assessed using the MMPI questionnaire. The scores of three validity scales and ten clinical scales were calculated and compared. Then the relationship between those scales and clinical characteristics of patients with BSP was analyzed in the BSP group. ResultsIt was found that patients with BSP scored significantly higher than healthy controls on the D, Hy, Pt clinical scales. The peak values of profiles were Hy, D, Hs scale scores. However, there was no statistical relationship between the clinical scales of MMPI and the clinical characteristics of BSP after Bonferroni Correction. ConclusionThe findings indicated that MMPI could be a useful psychometric tool to characterize a specific pattern of the personality of BSP patients and BSP patients may have avoidant and somatization personality characteristics.
