“…Kroeger and Sorensworth (2009) identified scheduled toilet sittings as a common component of many toilet training programs, which was taken from Azrin and Foxx's RTT method. Scheduled toilet sitting involves individuals sitting on or on front of the toilet (depending on sex and training protocol) at regular intervals (for example every 90 minutes) for a set period of time (for example 30 seconds), and is still employed in as part of multicomponent toileting programs today (Van Oorsouw, Duker, Melein, & Avernik 2010;Brown & Peace, 2011;Cocchiola, Martino, Dwyer, & Demezzo, 2012;Suppo & Mayton, 2012;Rinald & Mirenda, 2012;Kroeger & Sorensen-Burnworth, 2010;Lee et al, 2014;Drysdale et al, 2015;McLay et al, 2015;Axelrod et al, 2016). However, if an individual is demonstrating difficulty initiating trips to the toilet, that is, if the individual has not already started to approach the toilet independently for elimination, a new method, which involves scheduled chair sittings has been demonstrated to be successful to initiate this step which is vital to the maintenance of toileting success (Rinald & Mirenda, 2012;Kroeger & Sorensen-Burnworth, 2010).…”
