“…The above validity gaps also raise questions about whether sensor-based methods, such as data collection and scoring procedures, can be effectively and equitably applied to generate accurate estimates across samples. It is likely that there are inherent biases and assumptions about users that impact data-related decision making and interpretation (Raza et al, 2023). For instance, to our knowledge, only one study of infants has evaluated impact of shared versus nonshared sleep surfaces (e.g., bed- or couch-sharing) on the validity of accelerometer-based sleep estimates (Camerota et al, 2018), yet this sleep arrangement is common among families with young children, including toddlers and preschoolers, in many parts of the world (e.g., African and Asian countries/regions (Mileva-Seitz et al, 2017; Mindell et al, 2010), including among Black and Latine families with young children in the United States; Barajas et al, 2011).…”
