The unique objectives of the current investigation were: (a) to assess the fit of a multiinformant 2-factor measurement model of friendship quality in a clinical sample of children with attention-deficit/hyperactivity disorder (ADHD); and (b) to use a multiple indicators multiple causes approach to evaluate whether comorbid externalizing and internalizing disorders incrementally predict levels of positive and negative friendship quality. Our sample included 165 target children diagnosed with ADHD (33% girls; aged 6-11 years). Target children, their parents, their friends, and the parents of their friends independently completed a self-report measure of friendship quality about the reciprocated friendship between the target child and the friend. Results indicated that a multiinformant 2-factor measurement model with correlated positive friendship quality and negative friendship quality had good fit. The friendships of children with ADHD and a comorbid externalizing disorder were characterized by less positive friendship quality and more negative friendship quality than the friendships of children with ADHD and no externalizing disorder after controlling for the presence of a comorbid internalizing disorder. However, the presence of a comorbid internalizing disorder did not predict positive or negative friendship quality. These findings suggest that soliciting reports from parents in addition to children and friends, and measuring comorbid externalizing disorders, may be valuable evidence-based strategies when assessing friendship quality in ADHD populations.

注意缺陷多动障碍儿童的友谊质量和合并症的多指标多原因（MIMIC）模型。

当前研究的独特目标是：（a）评估注意力缺陷/多动症（ADHD）儿童临床样本中友谊质量的多信息两因素测量模型的适合性；（b）使用多指标，多原因的方法来评估共病的外在和内在障碍是否能逐步预测正负友谊质量的水平。我们的样本包括165位被诊断患有多动症的目标儿童（33％的女孩； 6-11岁）。目标儿童，他们的父母，他们的朋友和他们的朋友的父母独立完成关于目标儿童和朋友之间的相互友谊的友谊质量的自我报告。结果表明，具有正相关的友谊质量和负相关的友谊质量的多信息两因素测量模型非常合适。与多动症儿童和没有合并症的儿童的友谊相比，在控制了共病内部化症的存在之后，多动症和合并症的内在障碍的儿童的友谊的积极性和消极的友谊素质较弱。但是，合并症内在性障碍的存在并不能预测积极或消极的友谊质量。这些发现表明，在评估多动症人群的友谊质量时，除孩子和朋友之外，从父母那里征求报告，并衡量合并症是一种有价值的循证策略。
