“…Those classified as Multiple function/Anxious had high rates of hazardous drinking, but the multi-method group had highest psychopathology in general. Still, most studies on sub-groups focus on differences in the frequency of self-harm (Klonsky & Olino, 2008;Somer et al, 2015;Whitlock, Muehlenkamp, & Eckenrode, 2008;Xin et al, 2016), symptoms of mental illness (Ross & Heath, 2003;Stanford, Jones, & Hudson, 2016), psychosocial adjustment (Hamza & Willoughby, 2013), methods of self-harm (Andover, Pepper, Ryabchenko, Oricco, & Gibb, 2005), and suicidality (Andrewes et al, 2017;Xin et al, 2016). All considered, studies on sub-groups focus mostly on non-clinical or clinical adult samples, using questionnaires or structured data on mental illness.…”
