The number of hours of sleep, approximately 8, is an average that varies little from one culture to another. However, there are individual differences for this variable, which has permitted the establishment of certain sleep patterns. Many studies have focused on the relationship between psychological variables and sleep patterns, which have produced contradictory results. The purpose of the present investigation is to evaluate the extent of dimensions of extraverted and neurotic personalities and state-trait anxiety levels in women with different sleep patterns. In a sample of 300 young healthy adults, 34 women were selected, 17 women showed a long sleep pattern, 9 showed an intermediate sleep pattern and 8 showed a short sleep pattern (age X = 20.29 SD = 1.55). The results indicate that there are no significant statistical differences between psychological variables and sleep patterns, which concludes that there exists no relation between sleep duration and personality and anxiety factors.
