“…Dysregulation has been found to be relatively stable over time, highly heritable (approximately 54%–68% additive genetic factors), and to have fairly substantial shared environmental factors (approximately 18%–30%; Althoff, Rettew, Faraone, Boomsma, & Hudziak, 2006; Boomsma et al, 2006; Hudziak, Althoff, Derks, Faraone, & Boomsma, 2005). Recent studies have also demonstrated positive associations between dysregulation and risk for suicidality (Althoff et al, 2006, 2010; Ayer et al, 2009; Holtmann et al, 2011; Mbekou, Gignac, MacNeil, Mackay, & Renaud, 2014; Volk & Todd, 2007), bipolar disorder (Althoff et al, 2010; Biederman et al, 2009; Diler et al, 2009), aggression (Doerfler, Connor, & Toscano, 2010), oppositional defiant disorder, conduct disorder, attention deficit hyperactivity disorder (Volk & Todd, 2007), anxiety (Althoff et al, 2010), and substance use disorders (Holtmann et al, 2011). Particular combinations of the widely used anxious/depressed, attention, and aggression subscales (AAA; Achenbach, 1991) are often used to index dysregulation because of the associations between elevation on these scales and psychiatric outcomes and impairment (Ayer et al, 2009).…”
