Objectives: In this study the authors intended to investigate the relation between mood, objective sleep measurement, and subjective sleep perception; in a sample of patients diagnosed with DSM-IV insomnia we recruited in the Mennonite Christian Hospital in Hualien. Methods: Sleep logs and questionnaires were used to measure subjective sleep perception for one week. Objective sleep measures were also obtained using actigraphy for the concurrent period. Mood was assessed using self-report instruments. Results: Baron and Kenny's model was used to calculate the strength of the relation of variables and explore potential mediators. The results indicated that the association between mood and subjective sleep perception was significant (p<0.01). This association was significantly mediated by the objectively measured sleep (p<0.01). Conclusion: Perception of our sleep quality impact mood in a significant manner if the actual sleep we have is reduced.
