Introduction: Though self-reported questionnaires are a common method for assessing insomnia, these questionnaires are not specifically validated in Indian setting.The objective of this study was to develop a questionnaire for patients with insomnia, for Indian setting, and validate the newly developed questionnaire against standardized Athens Insomnia Scale (AIS). Material: In Face validity (Phase-I), the insomnia questionnaire was administered to 6 patients with insomnia and 6 healthy subjects, followed by the AIS (after 1-week), to understand the clarity and acceptability of the questionnaire. In Phase-II, developed questionnaires and AIS would be administered to 104 insomnia patients and 34 healthy subjects to assess reliability and validity. Data from Phase-I is presented here. Observations: Mean age and HMI of insomnia patients were 38.8±12.97 years and 25.17±1.95 kg/m2, respectively, while those of healthy subjects were 32.8±12.53 years and 22.13±3.13 kg/m2, respectively. The mean score (based on insomnia questionnaire and AIS) was 22.33±6.15 and 12.67±2.94 for insomnia patients and 3.33±4.80 and 0 for healthy subjects respectively. The responses were evaluated, and necessary changes were made in the insomnia questionnaire. Conclusions: The Phase-1 of the study indicates that the questionnaire can be used for validity and reliability testing in Phase-II.
