| Sumario: | Objectives: To develop an age-based norm-referenced scoring system for the Brief Infant Sleep Questionnaire - Revised (BISQ-R).Methods: In sum, 33,835 submissions (data sample 1) of the expanded and revised BISQ-R by caregivers of infants and toddlers (1-36 months) were analyzed in the US via a publicly-available smartphone application, Johnson's® Bedtime®. Three subscales were created: Infant Sleep (IS; 5 items), Parent Perception (PP; 3 items), and Parent Behavior (PB; 11 items). The scoring algorithm was based on an age-based normative system, and each subscale was scored using a weighted average of items. Primary application of the scoring model was performed on a follow up set of 16,531 submissions (data sample 2). Secondary application was tested on an original web-based ecology study (data sample 3). Tertiary application was tested using previously published datasets consisting of a longitudinal study (data sample 4) and randomized control trial behavioral intervention study (data sample 5).Results: Overall application of the scoring algorithm was confirmed across multiple samples. Each subscale (IS, PP, PB) and total score (T) is age referenced (scores range from 0 to 100). Cross-comparison between subscales across studies reveal consistent and convergent relationships.Conclusions: The BISQ-R provides a comprehensive assessment of infant and toddler sleep patterns, as well as parent perception and parent behaviors that may contribute to sleep outcomes. The age-based norm-referenced scoring system is publicly available to be used by researchers and clinicians.
