“…Somatic dysregulation (i.e., impairment in or pain related to basic bodily functions) was included in this domain based on to evidence that children may express emotional distress indirectly through somatic complaints and somatoform symptoms (Agnafors et al, 2019;Flaherty , 2013;Ford et al, 2013b;Vernberg et al, 2011). In addition, adults (Eslami et al, 2019;Littleton, 2015;Paras et al, 2009) and adolescents (Bonvanie et al, 2015;Espejo-Siles et al, 2020;Nixon et al, 2011;Rey et al, 2020) with a history of childhood sexual abuse or peer victimization are at risk for stress-related somatic complaints and bodily problems (i.e., functional gastrointestinal disorders, chronic nonspecific and pelvic pain, psychogenic seizures). Dissociation, which may occur either as psychological (e.g., depersonalization, derealization, alter personality states) or somatoform (e.g., unexplained paralysis or sensory experiences) symptoms, also was included in the DTD affect/somatic dysregulation domain, based on evidence that severe emotion dysregulation (e.g., alexithymia; impaired modulation of and recovery from extreme negative emotion states) is related to pathological dissociation in childhood (Hebert et al, 2020) and adulthood (Ford & Gomez, 2015;Powers et al, 2015;Van Dijke et al, 2010).…”
