The goal of this study was to develop and validate a measure of self-rated positive and negative beliefs about one's non-suicidal self-injury (NSSI), the Experiences of Self-Injury Questionnaire (ESIQ).
Psychometric properties and validation against NSSI severity and shame were tested in two U.S. and two U.K. samples of individuals who endorsed a history of NSSI.
Exploratory and confirmatory factor analyses indicated five factors. Subscales were labeled Positive Beliefs, Personal Dislike, Interpersonal Concern, Emotional Suppression, and Emotional Expression. The Positive Beliefs Subscale covers beliefs that NSSI is valuable. Scores on this subscale were associated with endorsement of NSSI frequency, NSSI urges, and perceived likelihood of future NSSI. Other subscales showed validity in that they all showed unique effects on outcome indices of NSSI severity or shame.
The ESIQ shows promise as a brief reliable measure of beliefs about and experiences of NSSI.
本研究旨在开发和验证一种自我评估非自杀性自我伤害（NSSI）的正、负信念的衡量标准，即自我伤害体验问卷（ESIQ）。
在两个美国和两个英国的有 NSSI 史的个体样本中，对其心理测量特性和对 NSSI 严重程度和羞耻感的验证进行了测试。
探索性和验证性因素分析表明有五个因素。子量表分别标记为积极信念、个人厌恶、人际关注、情绪压抑和情绪表达。积极信念子量表涵盖了认为 NSSI 有价值的信念。该子量表的得分与 NSSI 频率、NSSI 冲动和未来 NSSI 的可能性的认可有关。其他子量表在有效性方面表现出独特的作用，因为它们都对 NSSI 严重程度或羞耻感的结果指标产生了独特的影响。
ESIQ 有望成为一种衡量 NSSI 的信念和体验的简短可靠工具。
