The Brief Infant Sleep Questionnaire (BISQ) is a well-established multidimensional questionnaire widely used internationally. ObjectivesTo adapt the BISQ questionnaire to Spanish and analyse its reliability and validity. To explore its feasibility, both in the clinical context, and in epidemiological research. MethodsParticipants were parents of children between 3 and 30 months of age. The adaptation to Spanish (BISQ-E) was achieved by using both back translation and consensus, following the international guidelines.Reliability was determined by means of test–retest and measurement of agreement (Kappa value) between 2 forms of administration of the questionnaire (self-administration and clinical interview). Construct validity was established by analysing its correlation with a sleep diary. ResultsA total of 87 families/children participated. The test–retest reliability undertaken in 60 subjects was r=0.848 (P<.001). The kappa value was 0.939 (95% CI: 0.858–1.00, P<.001).The agreement between BISQ-E and the sleep diary was analysed in 27 families/children, with statistically significant values being obtained for the following variables: bedtime (r=0.731), hours of night sleep (r=0.726), hours of daytime sleep (r=0.867), and number of nocturnal awakenings (r=0.888) (P<.001). ConclusionsThe Spanish adaptation of the BISQ shows overall adequate validity and reliability for the evaluation of sleep in infants and pre-school children. Its use as a clinical tool, or for clinical-epidemiological research studies, is feasible. ER -
