This study aimed to validate the PROMIS® pediatric v2.0 Anger scale in the Dutch general population, provide reference data, and compare reliability and relative efficiency between the full-length scale, its short-form, computerized adaptive test (CAT), and Pediatric Quality of Life Inventory (PedsQLTM) emotional functioning (EF) subscale scores. Children (N = 1,328), representative of the Dutch population, were asked to complete the PROMIS pediatric Anger scale (8-18 years) and PedsQLTM (8-17 years). A graded response model (GRM) was fit to the data. Structural validity was assessed by checking item-fit statistics (S-X2, p < .001 = misfit). For construct validity, a moderate correlation (Pearson's r > 0.50) was expected between the Anger scale and PedsQLTM EF subscale score. Dutch mean T score based on the U.S. model was calculated to provide reference data and cut-offs. Standard error of measurement (SE(θ)) was used to assess reliability (SE(θ) < .32 = .90 reliability). Relative efficiency was calculated (1 - SE(θ)2/N items) to compare how good the measures performed relative to the amount of items administered. In total, 527 children completed the PROMIS pediatric Anger scale, of which 482 completed the PedsQLTM. Structural validity was sufficient as no items displayed misfit (S-X2 = 22.9-40.3, p > .001). The Anger scale score correlated moderately (Pearson's r = .64) with the PedsQLTM EF subscale score. Dutch mean T score was 44.20 (SD = 11.39), with cut-offs of >52.2 for moderate and ≥62.3 for severe symptoms. Reliable measurements were obtained at the population mean and >2SD in the clinically relevant direction. CAT outperformed all other measures in efficiency. The PROMIS pediatric Anger scale displayed sufficient psychometric properties within the Dutch population and reference data are available.

荷兰一般人群中患者报告结果测量信息系统 (PROMIS®) 儿童愤怒量表的心理测量特性。

本研究旨在在荷兰一般人群中验证 PROMIS® 儿科 v2.0 愤怒量表，提供参考数据，并比较全长量表、其简短形式的计算机自适应测试 (CAT) 和儿科生活质量量表 (PedsQLTM) 情绪功能 (EF) 分量表得分。代表荷兰人口的儿童 (N = 1,328) 被要求完成 PROMIS 儿科愤怒量表（8-18 岁）和 PedsQLTM（8-17 岁）。分级响应模型 (GRM) 适合数据。通过检查项目拟合统计数据（S-X2，p < .001 = 失配）来评估结构有效性。对于结构效度，预期愤怒量表和 PedsQLTM EF 分量表得分之间存在中等相关性（Pearson's r > 0.50）。荷兰平均 T 分数基于美国 计算模型以提供参考数据和临界值。测量标准误差 (SE(θ)) 用于评估可靠性（SE(θ) < .32 = .90 可靠性）。计算相对效率（1 - SE(θ)2/N 项目）以比较措施相对于管理项目数量的执​​行情况。总共有 527 名儿童完成了 PROMIS 儿科愤怒量表，其中 482 名完成了 PedsQLTM。结构有效性足够，因为没有项目显示不匹配（S-X2 = 22.9-40.3，p > .001）。愤怒量表得分与 PedsQLTM EF 分量表得分适度相关（Pearson's r = .64）。荷兰平均 T 得分为 44.20（SD = 11.39），中度的临界值 >52.2，重度症状的临界值 ≥62.3。在临床相关方向的总体平均值和 >2SD 处获得了可靠的测量值。CAT 在效率方面优于所有其他措施。PROMIS 儿科愤怒量表在荷兰人群中显示出足够的心理测量特性，并且有可用的参考数据。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
