The Perceived Stress Scale (PSS) and PROMIS Psychological Stress Experiences-Pediatric (PPSE) are two self-report instruments that have been used with adolescents to measure subjective feelings of stress. Stress is a critical construct to evaluate, as chronic stress can result in negative long-term consequences for an individual's physical and mental health. While the PSS is more commonly used in research and clinical practice, use of the PPSE is becoming more widespread. This increased usage necessitates a way to compare the measures, for example, when changing which instrument is used in practice or when combining data from the two measures in pooled analysis. After assessing linking assumptions, we used equipercentile linking to score-link the two measures on the raw score and T-score metrics for both longer forms (10 PSS items; 8 PPSE items) and shorter forms (4 PSS or PPSE items), yielding crosswalk tables (Open Science Framework: https://osf.io/9pzyk/) to convert scores on each measure to the metric of the other. Raw scores between measures (.670 ≤ r ≤ .794) were not sufficiently correlated for score linking. Therefore, linked scores were treated as predictions, rather than counterfactual values on the alternative measure. Further, confirmatory factor analyses revealed that this low correlation was primarily due to the low reliability and multidimensionality of the PSS, and the derived linking functions were found to have minimal bias. Recommendations for the use of these conversion tables by researchers and practitioners are provided. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

将感知压力量表与 PROMIS 青少年儿科心理压力体验联系起来。


感知压力量表 (PSS) 和 PROMIS 儿科心理压力体验 (PPSE) 是两种自我报告工具，已用于青少年测量主观压力感受。压力是评估的一个关键因素，因为慢性压力会对个人的身心健康造成长期负面影响。虽然 PSS 在研究和临床实践中更常用，但 PPSE 的使用也越来越广泛。这种增加的使用需要一种比较测量的方法，例如，当改变实践中使用的仪器时或在汇总分析中组合来自两种测量的数据时。评估链接假设后，我们使用等百分位链接对较长形式（10 个 PSS 项目；8 个 PPSE 项目）和较短形式（4 个 PSS 或 PPSE 项目）的原始分数和 T 分数指标的两个度量进行分数链接，产生人行横道表（开放科学框架：https://osf.io/9pzyk/）将每个度量的分数转换为另一个度量的度量。测量之间的原始分数 (.670 ≤ r ≤ .794) 对于分数链接而言相关性不充分。因此，关联分数被视为预测，而不是替代衡量标准的反事实值。此外，验证性因素分析表明，这种低相关性主要是由于 PSS 的低可靠性和多维性，并且发现派生的链接函数具有最小的偏差。提供了研究人员和从业人员使用这些转换表的建议。 （PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
