The Child Behavior Checklist (CBCL) and Strengths and Difficulties Questionnaire (SDQ) both measure emotional and behavioral problems in children and adolescents, and scores on the two instruments are highly correlated. When administrative needs compel practitioners to change the instrument used or data from the two measures are combined to perform pooled analyses, it becomes necessary to compare scores on the two instruments. To enable such comparisons, we score linked three domains (Internalizing, Externalizing, and Total Problems) of the CBCL and SDQ in three age groups spanning 2-17 years. After assessing linking assumptions, we compared item response theory (IRT) and equipercentile linking methods to identify the most statistically justifiable link, ultimately selecting equipercentile linking with loglinear smoothing due to its minimal bias and the ability to link raw SDQ scores with both T-scores and raw scores from the CBCL. We derived crosswalk conversion tables to convert scores on one measure to the metric of the other and discuss the use of these tables in research and practice.

《儿童行为检查表》（CBCL）和《长处和困难问卷》（SDQ）均用于测量儿童和青少年的情绪和行为问题，这两个工具的得分高度相关。当行政需求迫使从业者改变使用的工具，或者合并来自这两种测量方法的数据以进行汇总分析时，就需要比较这两种工具的得分。为了能够进行这种比较，我们对涵盖 2-17 岁三个年龄段的 CBCL 和 SDQ 的三个领域（内化问题、外化问题和总问题）进行了评分。在评估连接假设后，我们比较了项目反应理论（IRT）和等百分位连接方法，以确定最具统计学合理性的连接，最终选择等百分位连接和对数线性平滑，因为它的偏差最小，并且能够将 SDQ 的原始分数与 CBCL 的 T 分数和原始分数连接起来。我们得出了交叉转换表，以便将一个测量的分数转换为另一个测量的分数，并讨论了在研究和实践中使用这些表格的问题。
