Relationship between dissociative experiences, abnormal sleep experiences, and sleep quality in undergraduate students

Amaç: Üniversite öğrencilerinde disosiyatif deneyimler, uyku deneyimleri ve uyku kalitesi arasındaki ilişkiyi araştırmaktır. Yöntem: Çalışmaya 127 üniversite öğrencisi alındı. Katılımcılara, Disosiyatif Yaşantılar Ölçeği (DES), Iowa Uyku Deneyimleri Ölçeği (ISES) ve Pitssburg Uyku Kalitesi İndeksi (PUKİ) uygulandı. Bulgular: DES toplam ve DES Taxon puanları ile ISES toplam, ISES genel uyku deneyimleri alt ölçekleri arasında orta düzeyde ilişki bulundu. PUKİ uyku bozuklukları, uyku ilacı kullanma, gün içi disfonksiyon alt ölçek ortalamaları ve toplam puan ortalamaları ile ISES toplam ve genel uyku deneyimleri alt ölçek puanları arasında zayıf ilişki bulundu. Regresyon analizi sonucunda, DES toplam puanlarının genel uyku deneyimlerini büyük ölçüde ön gördüğü, bunun yanında PUKİ uyku bozuklukları alt ölçek ortalamalarının ISES genel uyku deneyimleri ile ilişki olduğu bulundu. Sonuç: Bu çalışmada disosiyatif deneyimler ve anormal uyku deneyimleri arasında anlamlı ilişki bulunmuş, bunun yanında uyku problemleri gibi uyku kalitesi ile ilişkili bazı değişkenlerin disosiyatif deneyimler ve genel uyku deneyimleri ile ilişkili olduğu görülmüştür.

Üniversite öğrencilerinde disosiyatif deneyimler, anormal uyku deneyimleri ve uyku kalitesi ilişkisi

Objective: To investigate the association between dissociative experiences, sleep related experiences and sleep quality. Method: 127 undergraduate students have completed the Dissociative Experiences Scale (DES), the Iowa Sleep Experiences Scales (ISES) and the Pittsburg Sleep Quality Index (PSQI). Results: DES total and DES Taxon scores were moderately correlated with total ISES and ISES General Sleep Experiences (GS) subscale scores. PSQI total scores as well as the scores from PSQI subscales of sleep disturbances, use of sleeping medication and daytime dysfunction were weakly correlated with total ISES and ISES GS subscale scores. DES and PSQI total and subscale scores were not correlated with the lucid dreaming (LD) subscale of ISES. DES total scores explained a considerable amount of variance in ISES GS scores. Sleep disturbances and use of sleeping medication as indicators of sleep problems, were related to ISES GS. Conclusions: The present study showed the association between dissociative experiences and nighttime experiences and further revealed that some aspects of general sleep quality, especially the ones related to sleep problems are also related to both dissociation and general sleep experiences.
