ABSTRACT
We evaluated the reliability of a French version of the Wisconsin Sleep Questionnaire designed to investigate snoring, obstructive apnoeas, and sleeping problems. The assessment of reliability included the study of internal consistency and the 3 months repeatability of the questionnaire. The questionnaire was first completed at a Center of Preventive Medicine by a random sample of 122 subjects from the community. Three months later the same form was mailed and 82 questionnaires were returned (67.2%). No significant differences existed between responders and nonresponders for anthropometric data or life habits. The internal consistency in each domain was good or satisfactory (Cronbach's alpha=0.67 to 0.81). The concordance between the answers at a 3-month interval was excellent for questions on ever snoring, frequency of snoring, gasping/choking during sleep, and breathing stops during sleep (Cohen kappa>0.60). The questions on snoring loudness, a history of sleep apnoea, and excessive daytime sleepiness were fairly reproducible (kappa 0.28 to 0.60). We found no difference in reproducibility by gender or age. In conclusion, this reliability assessment in a sample of middle-aged subjects from the community in northeastern France showed satisfactory internal consistency and 3-months reproducibility of the main questions of a French translation of the Wisconsin Sleep Questionnaire.
