Introduction: Sleep disorders are common but remain undiagnosed due to lack of awareness among masses as well as physicians. There is a need for a sleep questionnaire which is specific to Indian population, quick to understand as well as is a reliable screening device. Objective: To validate a sleep questionnaire as a basic screening tool. Material and Method: The questionnaire was prepared taking different situations into consideration, translated into Marathi as well as English. Ten subjects were randomly chosen and the test was administeredover an interval of one month by two experts to determine its intra-observer as well as inter-observer reliablity. The validity was further confirmed with NPSG (Nocturnal Polysomnogram) as a gold standard. Results: The kappa statistic was 0.92 for intra as well as inter-observer reliability. Validity was determined by evaluating fifty five subjects by way of self administered questionnaire followed by a NPSG (Nocturnal Polysomnogram). The sensitivity and specificity were found to be 80% and 75% by Baye\'s rule. Conclusion: The reliability of the questionnaire is excellent. By Landis method there is almost perfect agreement between Expert 1 and Expert 2.Also there is good sensitivity and specificity observed. It appears to be useful screening tool for identifying presence of sleep disorders.
