The Relationship between Transdiagnostic Constructs and Insomnia in Students

Insomnia is a universal phenomenon that many people experience and is characterized by difficulty in sleep initiation, maintaining sleep, waking up early in the morning, and inability to return to sleep. Due to its high prevalence and the effect of insomnia on the mental and physical performance of individuals, especially students, the present study aimed to investigate the relationship between transdiagnostic structures and insomnia disorder in students.

This was a cross-sectional study. Population of this study was 400 medical students of Zanjan University of Medical Sciences and Zanjan University, Zanjan, Iran, who were selected by non-random sampling method. Research tools included demographic characteristics questionnaire, Insomnia Severity Index (ISI), 12-question Intolerance of Uncertainty Scale (IUS), Difficulties in Emotion Regulation Scale (DERS), Anxiety Sensitivity Index-Third Edition (ASI-3), and Repetitive Thinking Questionnaire (RTQ). Research data were analyzed using LISREL software.

The average age of students was 21.54 years. Transdiagnostic constructs explained a total of 9% of insomnia disorders in students. Insomnia disorders in women were significantly higher than in men; moreover, in the single group was higher than in the married group.
