The "Reading the Mind in the Eyes" Test: Investigation of Psychometric Properties and Test-Retest Reliability of the Persian Version.

The psychometric properties of the Persian "Reading the Mind in the Eyes" test were investigated, so were the predictions from the Empathizing-Systemizing theory of psychological sex differences. Adults aged 16-69 years old (N = 545, female = 51.7 %) completed the test online. The analysis of items showed them to be generally acceptable. Test-retest reliability, as measured by Intra-class correlation coefficient, was 0.735 with a 95 % CI of (0.514, 0.855). The percentage of agreement for each item in the test-retest was satisfactory and the mean difference between test-retest scores was -0.159 (SD = 3.42). However, the internal consistency of Persian version, calculated by Cronbach's alpha (0.371), was poor. Females scored significantly higher than males but academic degree and field of study had no significant effect.

[Temperament and character personality dimensions in patients with bipolar I disorder]. / Bipolar duygudurum bozuklugu-1 hastalarinda mizaç ve kisilik özelligi boyutlari.

OBJECTIVES: To compare Cloninger's dimensions of temperament and character in patients with bipolar I disorder (BP-I) and healthy controls from the general population. MATERIALS AND METHODS: This cross sectional study included 96 BP-I patients (according to DSM-IV-TR criteria) that were admitted to a psychiatric hospital in Iran due to an acute episode of mania or depression, or a mixed episode during 2011. Following stabilization of the acute phase, the patients completed the 125-item Temperament and Character Inventory-Persian Version of (TCI-125-PV). The scale's 7 dimensions of temperament and character were compared between the bipolar group and 1212 healthy controls via independent samples t-test. Moreover, the correlation between temperament and character scores, and age, duration of disorder, and mood variables (depression and mania scores) were assessed using Pearson's correlation coefficient. RESULTS: The bipolar patients had significantly higher harm avoidance (P= 0.001), and lower reward dependency (P= 0.001), persistence (P =0.044), cooperativeness (P= 0.001), self-directedness (P= 0.001), and self-transcendence (P= 0.004) scores than the controls. Female patients had lower reward dependency (P= 0.001), self-directedness (P= 0.001), and cooperativeness (P= 0.001) scores than male patients. In addition, TCI-125- PV scores were not strongly correlated with depression or mania scores, duration of disorder, or marital status. CONCLUSION: The personality profiles of the BP-I patients differed from those of the controls. Lower self-directedness and cooperativeness scores in the bipolar group appeared to be associated with more immature personality traits.
