Sleep Latency and Duration Estimates Among Sleep Disorder Patients: Variability as a Function of Sleep Disorder Diagnosis, Sleep History, and Psychological Characteristics

Patient factors, including sleep quality, perceptions of habitual sleep time, and current psychopathology, potentially influence sleep time estimation. Whereas psychological factors may lead to exaggeration of sleep disturbance among some patients, sleep quality itself may also influence the congruence between subjective and objective indices of sleep.
