The present study derived a short form of the State-Trait Cheerfulness Inventory-Trait Version (STCI-T30) using an item response theory framework. Latent trait test-retest correlations and reliability across the latent continuum in the STCI-T30 remained high. Moreover, the STCI-T30 showed external validity with criterion variables (e.g., playfulness) and a short writing task completed by these participants was rated by unacquainted judges to infer the author's cheerfulness, seriousness, and bad-mood. Results suggested significant self-other and inter-judge agreement of cheerfulness, seriousness, and bad-mood and linguistic cues analysis suggested cheerfulness and bad-mood manifested through writing in tone, social processes, and affect.
本研究采用项目反应理论框架，推导出特质愉悦感量表（State-Trait Cheerfulness Inventory-Trait Version，STCI-T30）的简式版本。STCI-T30 在特质连续体上的潜特质重测信度和信度保持在较高水平。此外，STCI-T30 与效标变量（如玩乐性）具有外部效度，并且这些参与者完成的简短写作任务被不熟悉的评判者评分，以推断作者的愉悦感、严肃感和不良情绪。结果表明，愉悦感、严肃感和不良情绪在自我和他人以及评判者之间具有显著的一致性，语言线索分析表明愉悦感和不良情绪通过写作的语气、社交过程和情感表现出来。
