Self-harm behavior can begin in early adolescence, with the highest rates of self-harm, between 1990 and 2000 in England, being among adolescents aged 16 to 24 years and there being considerable risk of fatal and non-fatal repetition. Previous systematic reviews have identified risk factors for self-harm in adolescents, but not for the repetition of this behavior. The aim of this review was to synthesise the psychological, psychosocial and sociodemographic risk factors for self-harm repetition in adolescents. By searching four databases, 27 studies were identified and included in the review. Several psychological (e.g., psychiatric morbidity, features of previous self-harm, psychological distress), psychosocial (e.g., alcohol misuse, poor family and peer relationships) and sociodemographic (e.g., age, gender and ethnicity) risk factors were identified for self-harm repetition in adolescents. Several risk factors across all categories for self-harm overlapped with that of self-harm repetition, such as depression, alcohol misuse and female gender. The clinical implications of these findings for practitioners were discussed. As was the case with prior reviews in this area, comparability between studies was limited and a meta-analysis was not possible due to considerable heterogeneity in outcome definitions, measures and methodologies.

自残行为可以在青春期早期开始，自残率最高，在 1990 年至 2000 年间在英格兰发生，发生在 16 至 24 岁的青少年中，并且存在相当大的致命和非致命重复风险。以前的系统评价已经确定了青少年自残的风险因素，但没有确定这种行为的重复。本综述的目的是综合青少年自我伤害重复的心理、社会心理和社会人口学风险因素。通过搜索四个数据库，确定了 27 项研究并将其纳入该评价。几种心理（例如，精神病发病率、既往自残的特征、心理困扰）、社会心理（例如，酗酒、家庭和同伴关系不佳）和社会人口学（例如，年龄、性别和种族）确定了青少年重复自我伤害的风险因素。所有类别的自我伤害风险因素都与重复自我伤害的风险因素重叠，例如抑郁、酗酒和女性。讨论了这些发现对从业者的临床意义。与该领域之前的审查情况一样，研究之间的可比性有限，由于结果定义、测量和方法的异质性相当大，因此无法进行荟萃分析。
