Research has consistently reported an average age of onset for NSSI around 14 years (Ammerman, Jacobucci, Kleiman, Uyeji, & McClosky, 2017; Gandhi, Luyckx, Baetens, Kiekens, Sleuwaegen et al., 2018; Swannell, Martin, Page, Hasking, & St John, 2014), but recent studies indicate there is notable variations in age of onset.

This study examined how age of nonsuicidal self-injury (NSSI) onset relates to NSSI severity and suicidality using decision tree analyses (nonparametric regression models that recursively partition predictor variables to create groupings).

2018年2月26日 · Including suicide function here, however, allows for analysis of intention consistent with NSSI as part of a self-harm continuum. C. Recency and Frequency (and age of onset and cessation) 5. The following questions ask about your experience with intentionally hurting yourself. We know that this can be a difficult issue to think and talk about.

2017年11月7日 · The age onset of NSSI most often occurs in early adolescence, between 12 and 14 years (Nock et al., 2006; Muehlenkamp and Gutierrez, 2007; Cerutti et al., 2011), but findings have also reported NSSI behavior in children under the age of 12 (Barrocas et al., 2012).

Known rates of nonsuicidal self-injury, hurting oneself without the intent to die, are between ∼7% and 24% in samples of early adolescents and older adolescents, yet research has not reported rates for youth younger than 11 years old. Children as young as 7 years old report engaging in nonsuicidal self-injury.

2022年6月1日 · General distress partially mediated the effects of age and gender on NSSI. The association between general distress and NSSI was not significantly moderated by age, gender nor their interactions. Conclusions: Gender difference in NSSI is not a static gap, but evolves across time, widening in mid-adolescence and disappearing by early adulthood.

2023年4月18日 · The results showed that the prevalence of NSSI in adolescents aged 10–19 years was 14.3%, and the prevalence in young adults aged 20–29 years was 7.0%, significantly higher than in any other ...

This study examined how age of nonsuicidal self-injury (NSSI) onset relates to NSSI severity and suicidality using decision tree analyses (nonparametric regression models that recursively partition predictor variables to create groupings). Those with an …

5 天之前 · The lifetime prevalence of NSSI among youths in Singapore was 25.0%, and the 12-month prevalence was found to be 6.8%. The median age of onset for lifetime NSSI was 14 years. Significantly higher odds of lifetime NSSI were observed among youths aged 15–29 years, females, and youths with lower educational attainment.

There is general consensus that NSSI begins in early adolescence, with a main age onset of 12 years old. Even though only few studies have investigated NSSI within children younger than 12 years old (Kirchner et al., 2011; Barrocas et al., 2012; Sornberger et al., 2012).
