Examining the Psychometric Properties of the Brief Histrionic Personality Scale

The purpose of this study was to investigate the psychometric properties of the Histrionic Personality Scale including internal consistency, test-retest reliability, divergent validity, and convergent validity in Iranian culture and society.

For this purpose, the questions of this scale were first translated into Farsi, then by retranslating the questions from Farsi to English and comparing it with the original text, the accuracy of the translation was ensured. This study is descriptive research, and the studied population included 350 adults (231 women - 119 men) of Yazd province with at least a diploma education in the age range of 17 to 58, who were selected by convenience sampling method. Participants were asked to complete the Cosmetic Surgery Acceptance Scale and the Demonstration subscale in Short Form MMPI2.

The test-retest reliability (r=0.63) and the personality scale's internal consistency (0.83) were satisfactory .Convergent and divergent validity were assessed by calculating the correlation coefficients .Pearson correlation coefficient showed that there was a significant positive correlation between the presentation scale and cosmetic surgery acceptance (r=0.27). Also, there was a significant positive relationship between the presentation scale and the MMPI2 subscale (r=0.53) .These results confirm the convergent and divergent validity of the histrionic personality scale.

Based on the results, the histrionic personality scale proved to measure this construct with sufficient reliability and validity in Iranian samples in spite of the cultural differences of Iran, and then can be used in related research.
