Theory and research suggest that distinct self-damaging behaviours (SDBs; e.g., nonsuicidal self-injury [NSSI], restrictive eating, binge eating, drug misuse, alcohol misuse) share similar motives. However, few studies have used a common self-report inventory to investigate the shared relevance and relative salience of motives for SDBs. Accordingly, the present study: (1) examined whether self-report scales assessing intrapersonal motives (i.e., relieving negative emotions, enhancing positive emotions, punishing oneself) and interpersonal motives (i.e., bonding with others, conforming with others, communicating distress, communicating strength, reducing demands) have invariant factor structures across SDBs; and (2) compared the salience of these motives across SDBs.

不同的自残行为，相似的动机？测试非自杀性自伤、饮食失调和物质滥用动机的测量不变性


理论和研究表明，不同的自我伤害行为 （SDBs;例如，非自杀性自伤 [NSSI]、限制性饮食、暴饮暴食、药物滥用、酒精滥用）具有相似的动机。然而，很少有研究使用一个共同的自我报告量表来调查 SDB 动机的共同相关性和相对显著性。因此，本研究：（1） 检查了自我报告量表是否评估了个人内部动机（即缓解负面情绪、增强积极情绪、惩罚自己）和内部动机。个人动机（即与他人建立联系、顺从他人、沟通痛苦、传达力量、减少需求）在 SDB 中具有不变的因子结构;（2） 比较了这些动机在 SDB 中的显著性。
