Objective: To determine the reliability and validity of Persian version of “BEARS” (B=Bedtime Issues, E= Excessive Daytime Sleepiness, A=Night Awakenings, R=Regularity and Duration of Sleep, S=Snoring) pediatric sleep questionnaire. Setting: Two primary care pediatric clinics in Tehran, IRAN Methods: In the first step BEARS sleep questionnaire filled and in a 2 to 4 week period BEARS completed again (by another questioner) and all of the subjects visited by sleep specialists for diagnosis of sleep problem. To determine test-retest reliability findings of BEARS compared during the time and between different questioners. To determine criteria validity, findings of BEARS compared with experts’ diagnosis. Results: A total of 215 children (2-12 years old) were studied. From these 101 were in preschool age group (2-6 years old) and 114 in primary school age group (7-12 years old). All of the BEARS items in preschool age group and most of the items in school aged group had good to excellent test-retest reliability (P<0.05). Approximate to half of items in both age groups were valid (P<0.05). Conclusion: This study suggests that the use of BEARS (a simple brief screening tool for pediatric sleep problems) is a reliable and relatively valid sleep screening tool in children especially in Persian language.
