Understanding Challenging Behaviors in Autism Spectrum Disorder: A Multi-Component, Interdisciplinary Model.

Examples of hyper-responsiveness include “requests bathroom breaks very frequently” and “seems always to be hungry and/or thirsty.” Examples of hypo- or under-responsiveness include “never feels hungry and/or thirsty” and “may have a fairly significant health issue and never complains of symptoms (e.g., strep throat, urinary tract infection, broken finger, fever).” Examples of difficulty pinpointing the location of distress include “complains of feeling sick but cannot provide any specific symptoms” and, when asked if a bathroom is needed, “replies, ‘I don’t know’ or ‘maybe.’” Regarding setting events, external variables, such as air temperature and noise level, are relatively simple to record.
