饮食失调（ED）患者的非自杀性自伤（NSSI）患病率高得惊人。青少年似乎面临特别高的风险，因为 ED 和 NSSI 均在青春期中期发病。有人认为，人格可能是 ED 和 NSSI 背后的跨诊断机制。然而，与成人和/或社区样本相比，青少年临床样本很少受到关注。因此，本研究调查了 189 名 ED 女性住院患者样本中人格的作用（M = 15.93，SD = 0.98）。我们的结果证实了 ED 中 NSSI 的患病率很高，特别是在有暴饮暴食/清除行为 (ED-BP) 的患者中。 ED-BP 和限制性 ED 亚型 (ED-R) 之间存在气质差异。也就是说，与 ED-R 相比，ED-BP 患者表现出更多的避免伤害和更少的自我导向。无论 ED 亚型如何，NSSI 也存在气质差异：一生中经历过 NSSI 的 ED 患者表现出较少的自我导向性和更多的避免伤害的能力。有趣的是，只有最近参与 NSSI 的 ED 患者才表现出较少的新奇追求。这些气质特征应该被认为是治疗患有或不患有 NSSI 的青少年 ED 患者的关键机制。
Eating disorder (ED) patients show alarmingly high prevalence rates of Non-Suicidal Self-Injury (NSSI). Adolescents seem to be particularly at risk, as EDs and NSSI both have their onset in mid-adolescence. It has been suggested that personality could be a transdiagnostic mechanism underlying both EDs and NSSI. However, little attention has been given to adolescent clinical samples compared to adult and/or community samples. Therefore, the current study investigated the role of personality in a sample of 189 female inpatients with an ED (M = 15.93, SD = 0.98). Our results confirmed the high prevalence of NSSI in EDs, specifically in patients with bingeing/purging behaviours (ED-BP). Temperamental differences were found between ED-BP and the restrictive ED subtype (ED-R). Namely, ED-BP patients showed more harm avoidance and less self-directedness compared to ED-R. Temperamental differences were found in NSSI as well, regardless of ED subtype: ED patients who had engaged in NSSI during their lifetime reported less self-directedness and more harm avoidance. Interestingly, only ED patients who recently engaged in NSSI showed less novelty seeking. These temperamental profiles should be recognised as key mechanisms in the treatment of adolescent ED patients with and without NSSI.
