Non-suicidal self-injury in Mexican young adults: Prevalence, associations with suicidal behavior and psychiatric disorders, and DSM-5 proposed diagnostic criteria

The DSM-5 nonsuicidal self-injury disorder among incoming college students: Prevalence and associations with 12-month mental disorders and suicidal thoughts and behaviors

“…Several important findings warrant brief comment. First, consistent with recent work among young adults in the general population (Benjet et al., ), the proposed DSM‐5 criteria lead to more conservative prevalence estimates when considering severe NSSI. Although approximately one in six reported a history of self‐injury, and one in 10 reported past year NSSI, only 0.8% met criteria for NSSI‐D.…”

“…In addition, more work is needed regarding the diagnostic correlates of NSSI-D. Prior research has shown that NSSI commonly cooccurs with other mental health problems (especially emotional disorders and STB; Benjet et al, 2017;Bentley, Cassiello-Robbins, Vittorio, Sauer-Zavala, & Barlow, 2015;Taliaferro & Muehlenkamp, 2015), yet is not pathognomonic of any particular condition (see Selby, Kranzler, Fehling, & Panza, 2015). Initial studies among clinical samples confirm the diagnostic heterogeneity of NSSI-D, but also observed that individuals who meet disorder criteria present with a more clinical profile than those not meeting criteria (Glenn & Klonsky, 2013;In-Albon, Ruf, & Schmid, 2013;Washburn, Potthoff, Juzwin, & Styer, 2015).…”

Statistical Approaches for Highly Skewed Data: Evaluating Relations between Maltreatment and Young Adults’ Non-Suicidal Self-injury

“…Thus, the current investigation sought to illustrate and compare these approaches as applied to a contemporary clinical issue, namely NSSI. As reviewed earlier, studies demonstrate that NSSI data are highly skewed such that most people do not engage in NSSI, a sizable minority of individuals have on at least one occasion, and a smaller number have done so on many occasions (Benjet et al, 2017;Gillies et al, 2018). Researchers studying NSSI have employed different statistical techniques to deal with the skewness of NSSI, including transformation approaches (e.g., Boone & Brausch, 2016;Buser et al, 2019;Midkiff et al, 2018) and zero-inflated approaches that address the overabundance of non-injurers in most samples using either Poisson (e.g., Esposito et al, 2019;Fox et al, 2018;Kranzler et al, 2018;Yates, Tracy, et al, 2008;You & Leung, 2012) or negative binomial distributions (e.g., Allen et al, 2019;Glenn, Kleiman, Cha, Nock, & Prinstein, 2016;Schoenleber, Berenbaum, & Motl, 2014;Vergara et al, 2019).…”

“…Despite elevated rates of NSSI within some subpopulations (e.g., psychiatric inpatient adolescents; Nock & Prinstein, 2004), pooled prevalence estimates indicate that NSSI has a relatively low base rate, such that the number of individuals who do not endorse NSSI far exceeds the number that does (i.e., an overabundance of zeros). Moreover, a relatively small subset of individuals who engage in NSSI do so at a high frequency (i.e., the distribution is positively skewed; Benjet et al, 2017;Gillies et al, 2018).…”

“…In light of the prevalence of NSSI, as well as its clinical relevance as a marker of significant psychological distress and impairment (Benjet et al, 2017;Klonsky & Olino, 2008), research that uses appropriate methods to address the highly skewed nature of NSSI data is needed to evaluate NSSI predictors that have been suggested in prior studies. The etiologic contribution of child maltreatment experiences to later NSSI has received consistent empirical support in previous studies (e.g., Kaess et al, 2013;Lang & Sharma-Patel, 2011;Liu, Scopelliti, Pittman, & Zamora, 2018;Serafini et al, 2017).…”
