The test—retest method, with an average interval of 72 days, was used to examine the reliability of Form A of the EPI on 72 Indian South African Std 9 high school girls (mean age = 16,928 years) and 70 Std 9 high school boys (mean age = 17,296 years). Reliability coefficients were calculated for the E, N, and L scales for boys, girls, and the sexes combined. The reliabilities were acceptable for all groups, with the lowest coefficient being 0,715, suggesting that Form A of the EPI is reliable for use with Indian South African 15–18-year old subjects.
