Dysparenting, referring to inappropriate parental attitudes, is a vulnerability factor for mental disorders during adolescence and a therapeutic leverage, yet clinicians lack reliable tools to assess it in daily clinical practice. Moreover, the effect of this dysparenting on the amount of psychiatric care remains unclear. The Family and Care study aims to develop the at-risk family interactions and levers (ARFIL) scale, a comprehensive 30-item clinical scale, and to assess in a cross-sectional design, the impact of these at-risk family interactions on the care of adolescents (n = 425) hospitalized in psychiatry and aged 13–19 years old. Factorial analysis shows that the ARFIL scale consists of three main dimensions associated with cohesion/conflicts, love/hostility, and autonomy/control with good psychometric properties. Multivariate regressions show that the ARFIL intensity score predicts the duration of hospital care, regardless of age, gender, medical severity on admission, assessed by the Global Assessment of Functioning scale, the presence of maltreatment and psychiatric diagnoses. Moreover, the ARFIL diversity score (number of items present regardless of their severity) predicts both the number and duration of hospitalizations. At-risk family interactions are a determining dimension of psychiatric adolescent care, and the ARFIL scale could constitute a valuable tool, not only for holistic evaluation and treatment, but also for prevention.

父母态度不当是指父母态度不当，是青春期精神障碍的一个脆弱因素，也是一种治疗杠杆，但临床医生在日常临床实践中缺乏可靠的工具来评估它。此外，这种父母不和对精神科护理量的影响仍不清楚。家庭与护理研究旨在开发高危家庭互动和杠杆 (ARFIL) 量表，这是一个包含 30 项的综合临床量表，并通过横断面设计评估这些高危家庭互动对 13-19 岁住院精神科青少年 ( n = 425)的护理。因子分析表明，ARFIL量表由与凝聚力/冲突、爱/敌意和自主/控制相关的三个主要维度组成，具有良好的心理测量特性。多变量回归显示，ARFIL 强度评分可以预测住院治疗的持续时间，无论年龄、性别、入院时的医疗严重程度如何，通过整体功能评估量表进行评估、是否存在虐待和精神病诊断。此外，ARFIL 多样性评分（无论其严重程度如何，存在的项目数量）可以预测住院次数和住院时间。高危家庭互动是青少年精神科护理的一个决定性因素，ARFIL 量表可以成为一个有价值的工具，不仅可以用于整体评估和治疗，还可以用于预防。
