Family influence is a crucial factor in the onset and maintenance of eating disorders. Nonsuicidal self-injury (NSSI) and restrictive eating disorders (REDs) co-occur in a significant percentage of subjects but family functioning of these families remains underexplored. This study examines the family functioning perceptions of 80 families with adolescents experiencing RED, comparing those with and without NSSI, alongside a control group, utilising the FACES-IV assessment. The study also aims to compare the triadic (adolescent–mother–father) perception of family functioning in the three groups. The results reveal distinct family dynamics in adolescents with both RED and NSSI, marked by problematic functioning perceptions from all family members and low parental agreement. A further understanding of the family functioning of adolescents with RED with NSSI can help clinicians in defining the treatment setting.

有或没有非自杀性自残的限制性饮食障碍青少年的家庭功能

家庭影响是饮食失调发生和维持的关键因素。非自杀性自残（NSSI）和限制性饮食失调（RED）在相当大比例的受试者中同时发生，但这些家庭的家庭功能仍未得到充分研究。本研究利用 FACES-IV 评估，调查了 80 个有 RED 青少年的家庭对家庭功能的看法，比较了有和没有 NSSI 的家庭以及对照组。该研究还旨在比较三组人对家庭功能的三元组（青少年-母亲-父亲）看法。结果揭示了患有 RED 和 NSSI 的青少年的不同家庭动态，其特点是所有家庭成员的功能认知存在问题以及父母的一致性较低。进一步了解患有 NSSI 的 RED 青少年的家庭功能可以帮助临床医生确定治疗环境。
