The present study developed and validated a short form of the Cross-Cultural (Chinese) Personality Assessment Inventory for adolescents (CPAI-A; Form B) focusing on the personality scales by unidimensional and multidimensional Rasch models. Multiple evidence from unidimensional Rasch models (item fit, DIF statistics, dimensionality, reliability indices, construct coverage) were evaluated in order to create a short scale with optimal psychometric properties. Further, multidimensional Rasch model, canonical analysis, and predictive validity were performed and evaluated to validate the CPAI-A-SF further. As a result, 65 of 277 items were selected in the short measure with a four-dimensional structure. The infit and outfit mean-squares (MNSQ) of the personality scale items ranged between .81 and 1.25. Good construct coverage was displayed on the item-person map, and all four dimensions demonstrate reasonable EAP/PV reliability ranging from .81 to .87. The personality scores of CPAI-A-SF predicted life satisfaction as well as the scores from the original inventory.
本研究采用一维和多维 Rasch 模型，开发并验证了青少年跨文化（中文）人格评估量表（CPAI-A；B 型）的简短形式，重点是人格量表。为了创建具有最佳心理测量特性的简短量表，从一维 Rasch 模型（项目拟合、DIF 统计、维度、信度指标、结构覆盖）中评估了多种证据。此外，还进行了多维 Rasch 模型、典型分析和预测有效性分析，以进一步验证 CPAI-A-SF。结果，在具有四维结构的简短量表中选择了 277 个项目中的 65 个。人格量表项目的 infit 和 outfit 均方根（MNSQ）在.81 和 1.25 之间。项目-人图谱上显示出良好的结构覆盖，所有四个维度的 EAP/PV 可靠性均合理，范围在.81 到.87 之间。CPAI-A-SF 的人格得分预测了生活满意度以及原始量表的得分。
