One thousand four hundred and twenty-five female undergraduates, ranging in age from 18 to 28 years, were administered a 26-item questionnaire asking about the frequency of nightmares and a 26-item questionnaire on the frequency of dream recall (Okada, 2001, 2011). Results indicated that 4.6% of respondents reported experiencing nightmares once or twice a week, and this figure agrees with the findings of Levin and Nielsen (2007). Factor analysis of the questionnaire indicated that items on the frequency of dream recall fell into five categories: major perceptions, minor perceptions, positive emotions, negative emotions, and dream content. The frequency of nightmares was associated with both types of perceptions as well as negative emotions and negative dream content. 文教大学 2014-03-01 jpn departmental bulletin paper VoR https://bunkyo.repo.nii.ac.jp/records/2873 03882152 人間科学研究 Bulletin of Human Science 35 10 81 90 https://bunkyo.repo.nii.ac.jp/record/2873/files/BKK0002913.pdf application/pdf 868.8 kB 2018-03-22
