This research explored the ability of parent-informant Personality Inventory for Children (PIC; Lachar, 1982) questionnaire items to form the foundation for self-report scales. An iterative rational and internal consistency approach using 585 clinical protocols constructed nine nonoverlapping clinical scales. Twenty-four complementary subscales were also constructed through scale item analysis. Acceptable estimates of scale reliability and internal consistency were established in substantial, diverse normal and clinical samples. Personality Inventory for Youth scales effectively separated normal and clinical protocols. Age and sex effects were investigated as were correlations with parent-informant PIC scales. Follow-up research includes the development of validity and adjustment screening scales, as well as the collection of diverse psychometric and clinical rating data to advance scale construct validity.
本研究探讨了由父母报告的儿童个性问卷（PIC；拉查尔，1982）项目作为自我报告量表基础的能力。采用迭代的理性和内部一致性方法，基于585份临床记录构建了9个不重叠的临床量表。还通过量表项目分析构建了24个补充性子量表。在大量不同的正常和临床样本中，建立了量表信度和内部一致性的可接受估计值。青少年个性问卷量表有效地将正常记录和临床记录区分开来。研究了年龄和性别效应以及与父母报告的PIC量表的相关性。后续研究包括效度和适应性筛查量表的开发，以及收集各种心理测量和临床评定数据，以推进量表结构效度的研究。
