Purpose Excessive self-criticism, along with negative self-evaluation and perceived unfavorable judgments from others, often leads to emotional distress. The Levels of Self-Criticism (LOSC) scale identifies two distinct forms of self-criticism: comparative self-criticism and internalized self-criticism, yet with varying psychometric stability across different populations. Method This study developed a shortened, psychometrically robust version of the LOSC by employing item response theory (IRT) and factor analysis to enhance the practicality and reliability of the scale. Results 415 participants completed the baseline survey, and 232 completed the post-test, engaging 83% of females with Mage = 39.73. IRT analysis eliminated 11 items, with the remaining items demonstrating optimal item performance and significant concurrent validity with related measures. This shortened LOSC showed strong test–retest reliability and construct validity. Discussion This streamlined scale provides a precise tool for assessing self-criticism, contributing to better psychological practice and research.

开发 22 项自我批评量表的简化版本：使用项目反应理论和因子分析


目的 过度的自我批评，以及消极的自我评价和感知到的来自他人的不利评判，往往会导致情绪困扰。自我批评水平 （LOSC） 量表确定了两种不同的自我批评形式：比较自我批评和内化自我批评，但不同人群的心理测量稳定性不同。方法 本研究通过采用项目反应理论 （IRT） 和因子分析来增强量表的实用性和可靠性，开发了一种简短的、心理测量学稳健的 LOSC 版本。结果 415 名参与者完成了基线调查，232 名参与者完成了后测，让 83% 的女性参与其中 Mage = 39.73。IRT 分析消除了 11 个项目，其余项目表现出最佳的项目性能和与相关措施的显着并发效度。这种缩短的 LOSC 显示出很强的重测信度和结构效度。讨论 这种简化的量表为评估自我批评提供了精确的工具，有助于更好的心理学实践和研究。
