Prediction of Sleep Disorders Based on Psychological Distress and Emotional Dysregulation in Adolescent Girls

The present study aimed to predict sleep disorders based on psychological distress and emotional dysregulation among adolescent girls.

This research employed a descriptive-correlational design. The statistical population included all adolescent girls studying in secondary high schools in Tehran during the first semester of the 2024-2025 academic years, totaling 87,222 students. A sample size of 300 participants was determined and selected using a multistage cluster random sampling method. Data were collected using the Sleep Disorders Questionnaire, the Psychological Distress Scale and the Emotional Dysregulation Questionnaire. Statistical analyses were performed using SPSS version 27.

The results showed that 45.3% of the variance in sleep disorders was predicted by psychological distress and emotional dysregulation. There was a positive and significant relationship between psychological distress and sleep disorders (β = 0.645). Moreover, emotional dysregulation was positively and significantly related to sleep disorders (β = 0.576). Additionally, stress (β = 0.669), anxiety (β = 0.630), and depression (β = 0.450) showed positive and significant associations with sleep disorders.

Based on the findings, psychological distress and emotional dysregulation play significant roles in predicting sleep disorders and explain a considerable proportion of their variance. Therefore, interventions targeting these psychological variables may help improve sleep quality and enhance mental health among individuals.
