There has been an increasing body of literature that focuses on identifying sleep problems in children with developmental disabilities (DD), with the primary aim of determining the prevalence and describing the sleep problem (Glickman, 2010). Across a number of studies, the most commonly reported sleep problems in children with DD have been irregular sleep-wake patterns that include difficulty maintaining sleep, delayed sleep onset, early morning waking and/or impaired alertness during waking hours (Glickman, 2010). These suggest the involvement of the circadian system (i.e., related to where sleep occurs in the 24h cycle) (Glickman, 2010; Diomedi et al., 1999; Elia et al., 2000; Patzold et al., 1998; Richdale and Prior, 1995; Wiggs and Stores, 2004). For this reason, examining circadian disturbances in children with DD will be vital to a better understanding if it is affiliated with the presenting sleep problems and if circadian interventions will suffice to treat the sleep problems in children with DD (Glickman, 2010). However, the focus of the current study is on manipulating the circadian rhythm (e.g., bedtime fading with/without response cost) to see if it is a sufficiently contributing factor to their sleep problem.
