Parent and family characteristics are important considerations in the etiology and treatment of childhood disruptive behavior problems. The current study investigated the psychometric properties of the General Functioning (GF) scale of the McMaster Family Assessment Device (FAD) in families referred for treatment of childhood disruptive behavior difficulties. Participants included 459 families with a child between the ages of 6 and 12 years who were referred for treatment of disruptive behavior. Prior to treatment, mothers and/or fathers completed questionnaires assessing family functioning, child psychopathology and associated functional impairment, parenting behavior, and parent psychopathology. The factor structure, internal consistency, and concurrent validity of three versions of the FAD GF scale were examined, including a one-factor, 12-item model, a one-factor, 6-item model, and a 3-factor, 12-item model. All three models had adequate fit based on confirmatory factor analysis. Across models, family dysfunction scores had small positive associations with child psychopathology, functional impairment, inconsistent parenting behaviors, and parents’ history of internalizing disorders, and small negative associations with positive parenting behaviors, providing evidence for the concurrent validity of the scale. The FAD GF scale provides a valid and reliable measure of family dysfunction in families experiencing disruptive child behavior. Researchers and clinicians may consider using an abbreviated 6-item version of the scale or a three-domain version of the scale as valid alternatives to the standard 12-item administration and scoring.

父母和家庭特征是儿童破坏性行为问题的病因和治疗的重要考虑因素。目前的研究调查了麦克马斯特家庭评估装置（FAD）的一般功能（GF）量表的心理测量特性，该装置用于治疗儿童破坏性行为困难的家庭。参与者包括 459 个有 6 岁至 12 岁儿童的家庭，他们被转介接受破坏性行为治疗。在治疗之前，母亲和/或父亲完成了评估家庭功能、儿童精神病理学和相关功能障碍、养育行为和父母精神病理学的调查问卷。检查了 FAD GF 量表三个版本的因子结构、内部一致性和同时效度，包括单因子 12 项模型、单因子 6 项模型和 3 因子 12 项模型。项目模型。根据验证性因素分析，所有三个模型都具有足够的拟合度。在各个模型中，家庭功能障碍评分与儿童精神病理学、功能障碍、不一致的养育行为和父母内化障碍史有较小的正相关，与积极的养育行为有较小的负相关，这为该量表的同时有效性提供了证据。FAD GF 量表为经历破坏性儿童行为的家庭提供了有效且可靠的家庭功能障碍衡量标准。研究人员和临床医生可以考虑使用缩减的 6 项目版本量表或三域版本量表作为标准 12 项目管理和评分的有效替代方案。
