Using measurement-based and feedback-informed approaches is key to providing effective family-centered clinical care; a strength-based approach is shown to improve treatment outcomes and satisfaction. Yet, there are few brief, psychometrically sound assessment tools for preschool-aged and elementary school–aged children. In response, we developed a nine-item, two-scale measure, the Weekly Assessment of Child Behavior–Positive (WACB-P), suitable for children aged 2 to 12 years. We examined the psychometric properties of the WACB-P based on two low-income, clinical samples differing in intervention modality and location (Sample 1: N = 285; Sample 2: N = 137). WACB-P demonstrated high internal validity and test–retest reliability. The item response theory (IRT) paradigm applied to the Intensity Scale revealed that the items showed moderate discrimination and adequate precision, particularly effectively capturing behavioral challenges. Repeated-measures analysis of covariance (RM-ANCOVA) showed significant linear effects from session to session, suggesting sensitivity to change during treatment. WACB-P demonstrated strong convergent validity with established measures of child behavior problems. These favorable results position the WACB-P as a suitable choice for agencies providing measurement-based behavioral health care for young children and their families.

使用基于测量和反馈的方法是提供有效的以家庭为中心的临床护理的关键；一种基于力量的方法被证明可以改善治疗效果和满意度。但是，几乎没有针对学龄前儿童和小学学龄儿童的简短的，从心理上讲合理的评估工具。作为回应，我们制定了一项九项，两尺度的量度，即“适合儿童行为的每周评估”（WACB-P），适用于2至12岁的儿童。我们基于两种低收入，干预方式和位置不同的临床样本研究了WACB-P的心理测量特性（样本1：N = 285；样本2：N= 137）。WACB-P具有很高的内部有效性和重测可靠性。应用于强度量表的项目反应理论（IRT）范式表明，项目显示出中等的辨别力和足够的精确度，尤其有效地捕捉了行为方面的挑战。重复测量的协方差分析（RM-ANCOVA）显示，每个疗程之间存在显着的线性效应，表明治疗期间对变化的敏感性。WACB-P具有确定的儿童行为问题测度，显示出强大的收敛效度。这些良好的结果将WACB-P定位为为幼儿及其家庭提供基于度量的行为保健的机构的合适选择。
