The Prodromal Questionnaire-Brief Child Version (PQ-BC) has been developed as a tool for identifying psychotic-like experiences (PLEs) in school-age children. The current study examined the psychometric properties of the PQ-BC, examined how well the PQ-BC estimates the latent construct of PLEs (θ̂), and began the process of developing a screening form informed by item response theory (IRT). Utilizing the baseline (N = 11,129) sample from the Adolescent Brain Cognitive Development study, we examined which PQ-BC items provide the most information and best discriminate individuals experiencing PLEs. Using hierarchical linear models (HLMs), we found that θ̂ scores were significantly associated with several previously identified predictors of psychosis spectrum symptoms (i.e., history of psychosis, internalizing symptoms, cognitive impairments, developmental milestone delays, and resting-state functional connectivity impairments) at baseline and Year 1 (n = 5,532). Using item-level information and discrimination parameters of the PQ-BC from the baseline sample, we created a 7-item screening form. HLMs generally found significant associations between screening form scores for both baseline and Year 1 with the aforementioned predictors. The analyses provide evidence for the validity of a screening form derived from the PQ-BC using IRT-derived parameters. This screening form could prove useful when the full measure is not feasible.

前驱问卷简明儿童版的项目反应理论分析:开发筛查表,以了解对儿童自报的精神病样经历的理解。

前驱问卷-简明儿童版(PQ-BC)已被开发为识别学龄儿童精神病样经历(PLEs)的工具。当前的研究检查了PQ-BC的心理测量特性,检查了PQ-BC对PLEs的潜在结构的估计程度(θ̂),并开始了根据项目反应理论(IRT)制定筛选表的过程。利用来自青少年脑认知发展研究的基线(N = 11,129)样本,我们检查了哪些PQ-BC项目提供最多的信息并最好地区分经历PLE的个体。使用分层线性模型(HLM),我们发现θ̂得分与先前确定的精神病频谱症状的几个预测因子(即精神病史,内在症状,认知障碍,基线和第1年(n = 5,532)的发展里程碑延迟和静息状态功能连接障碍)。使用来自基线样本的PQ-BC的项目级信息和判别参数,我们创建了一个7个项目的筛选表。HLM通常发现基线和1年级的筛查形式分数与上述预测因素之间存在显着关联。该分析为使用IRT衍生的参数从PQ-BC衍生的筛查表格的有效性提供了证据。当全面措施不可行时,该筛选表可能会有用。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。使用来自基线样本的PQ-BC的项目级信息和判别参数,我们创建了一个7个项目的筛选表。HLM通常发现基线和1年级的筛查形式分数与上述预测因素之间存在显着关联。该分析为使用IRT衍生的参数从PQ-BC衍生的筛查表格的有效性提供了证据。当全面措施不可行时,该筛选表可能会有用。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。使用来自基线样本的PQ-BC的项目级信息和判别参数,我们创建了一个7个项目的筛选表。HLM通常发现基线和1年级的筛查形式分数与上述预测因素之间存在显着关联。该分析为使用IRT衍生的参数从PQ-BC衍生的筛查表格的有效性提供了证据。当全面措施不可行时,该筛选表可能会有用。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。当全面措施不可行时,该筛选表可能会有用。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。当全面措施不可行时,该筛选表可能会有用。(PsycINFO数据库记录(c)2020 APA,保留所有权利)。
