The aim of this study was to investigate the effects of psychological factors on sleep initiating process. The Y‐G personality test (Y‐G), Lazarus‐type stress coping inventory (SCI), Zung self‐rating depression scale, General health questionnaire, and Sleep health questionnaire were administered to 418 subjects (mean age = 21.13 ± 8.76 years), and the data were analyzed by multiple regression analysis (stepwise variable reduction method). Self‐rating depression scale; Co‐Em, Pla, Sel scale in SCI; C, N, O, Co scale in Y‐G were significantly included in the final model. The results showed that psychological factors, such as depression, emotion‐focused coping behaviour, prudent planning to solve problems, low self‐control, small changes of feeling, nervousness, subjectiveness, and cooperativeness are associated with difficulty initiating sleep.
