 AbstractIntroduction: Since interpersonal differences can be assessed using the self-reported personality characteristics, this study aimed to validate and standardize of the revised Eysenck Personality Questionnaire (EPQ-R) in different age groups of an Iranian sample.Method: A sample of 1212 men and women completed EPQ-R in Tehran. Statistical analysis was done to assess internal consistency and material analysis. One to two months later, 101 of the whole sample were randomly selected and retested using the same questionnaire. Moreover, to assess validity, 100 of the respondents were randomly selected and interviewed by two in-dependent psychologists.Results: The test-retest reliability coefficients showed that there is internal consistency for 6 subscales of EPQ-R. Correlations between ratings and scores showed high validity in all subscales. Inter-correlations showed that E is distinct from P there is a weak negative correlation between E and N and a weak correlation between P and N. Factor analysis revealed that A and C are correlated with P, N, and E. Conclusion: EPQ-R is reasonably valid and reliable.
