Physical, social, and psychological outcomes have been identified as relevant to the rehabilitation process of children with burn injuries. Existing legacy measures are limited in item content and only cover a few constructs. Condition-specific outcomes are highly relevant to gauge early growth and development. Computerized adaptive tests (CATs) leveraging advanced psychometric technologies minimize respondent burden. This project developed PS-LIBRE1-5 Profile CAT (Preschool Life Impact Burn Recovery Evaluation) to measure relevant postburn outcomes in children aged one to five. Responses to the field-tested PS-LIBRE1-5 Profile (188 items) were measured on a scale of frequency or ability. Scores were coded from 0 to 4 where higher scores reflected better functioning. Factor analysis identified the items retained in the final item bank of each scale. CAT simulations were conducted to estimate the mean score of each scale. The simulated CAT score and full item bank scores were compared based upon the score range, ceiling and floor effects, and marginal reliabilities. The child mean age was 3.0 ± 1.5 years (n = 500). Average burn size and time since burn injury were 4.2% TBSA and 1.1 years, respectively. Psychometric analysis resulted in eight scales: Physical, Communication and Language, Emotional Wellbeing, Mood, Anxiety, Peer Acceptance, Play, and Peer Relations. Ceiling effects were acceptable at <13% for all scales. Marginal reliabilities of the CATs were credible. The PS-LIBRE1-5 Profile CAT contains 111 items, and is a comprehensive measure that captures physical, communication and language, psychological, and social functioning of preschool burn survivors.
身体、社会和心理结果已被确定为儿童烧伤康复过程中的相关因素。现有的传统测量方法在项目内容上存在局限性，仅涵盖了少数几个结构。特定于病情的结果对于衡量早期的生长和发育非常重要。利用先进心理测量技术的计算机化自适应测试 (CAT) 可以最大限度地减少受访者的负担。本项目开发了 PS-LIBRE1-5 简档 CAT（学前生活影响烧伤康复评估），以衡量 1 至 5 岁烧伤儿童的相关烧伤后结果。对经过现场测试的 PS-LIBRE1-5 简档（188 个项目）的反应在频率或能力的尺度上进行衡量。分数从 0 到 4 编码，分数越高表示功能越好。因素分析确定了每个量表中保留的最终项目库中的项目。进行 CAT 模拟以估算每个量表的平均分数。根据得分范围、天花板和地板效应以及边缘可靠性，比较模拟 CAT 得分和完整项目库得分。儿童的平均年龄为 3.0 ± 1.5 岁（n = 500）。平均烧伤面积和烧伤后时间分别为 4.2% TBSA 和 1.1 年。心理测量分析产生了八个量表：身体、沟通和语言、情绪健康、情绪、焦虑、同伴接受、玩耍和同伴关系。所有量表的天花板效应均<13%，可接受。CAT 的边缘可靠性是可信的。PS-LIBRE1-5 简档 CAT 包含 111 个项目，是一种全面的测量工具，可捕捉学龄前烧伤幸存者的身体、沟通和语言、心理和社会功能。
