Summary
AI-generated from the abstractEight-point scales for measuring how often people have lucid dreams and nightmares are reliable. When 93 sport students completed the scales twice, four weeks apart, the lucid dream frequency scale showed a test-retest reliability of r = 0.89 and the nightmare frequency scale a reliability of r = 0.75. Both scales are dependable tools for assessing individual differences in these dream experiences.

Abstract
Lucid dream and nightmare frequencies vary greatly between individuals and to assess these differences reliable instruments are needed. The present study aimed to examine the reliability of eight-point scales for measuring lucid dream and nightmare frequencies. The scales were administered twice (with a four-week interval) to 93 sport students. A re-test reliability for the lucid dream frequency was found r=.89 (p<.001) and for the nightmare frequency r=.75 (p<.001). Both eight-point scales appear to be reliable measures for assessing individual differences in lucid dream and nightmare frequencies.
