Emotional reactivity\u2014including sensitivity, intensity, and persistence\u2014may be associated with NSSI through its relationship with adolescents\u2019 capacity to tolerate emotional distress, and this indirect association may differ by gender.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A total of 3,640 adolescents (M\n                      <jats:sub>age<\/jats:sub>\n                      = 18.27, SD\u00a0=\u00a01.45; 52.34% were male) completed measures of emotional reactivity, distress tolerance, and NSSI behaviors. Structural equation modeling was used to examine the mediating role of distress tolerance in the link between emotional reactivity and NSSI, and multi-group analyses were conducted to explore gender-related patterns.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Emotional reactivity was significantly and positively associated with NSSI. Distress tolerance mediated the association between emotional reactivity and NSSI: higher emotional reactivity was associated with lower distress tolerance, which in turn was associated with higher levels of NSSI. Gender-stratified analyses showed that the indirect effects were significant among females but not males. Further examination of the dimensions of emotional reactivity revealed that gender differences were significant for emotional intensity but not for emotional sensitivity or emotional persistence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that distress tolerance is a key psychological factor underlying the association between emotional reactivity and NSSI, with this association being particularly salient among female participants.
