This study aims to develop a short Japanese version of the Self-Stigma of Stuttering Scale (4S), which assesses the self-stigma of adults who stutter (AWS) in a self-completed form, and evaluate its psychometric properties and reliability and validity.
After translating the original 4S scale into Japanese (4S-J) through a forward-backward translation process, it was administered to 123 Japanese adults who stutter. A short version of the 4S-J was developed through factor analysis and eliminating items with low loadings to original factors. Reliability was verified by calculating internal consistency and test-retest reliability. Participants also completed the Japanese-translated version of the Rosenberg Self Esteem Scale, General Self-Efficacy Scale, and Subjective Happiness Scale to verify construct validity. As a secondary analysis, our results regarding psychological properties of the short version of the 4S were then compared to those of studies from other countries.
Sixteen items were selected for the short version of the scale (4S-J-16), and confirmatory factor analysis verified the original structure of the 4S. We obtained good internal consistency and test-retest reliability. Regarding construct validity, our results showed similar correlation with the other selected scales. The value of all scores on the stigma scale in the Japanese cohort was significantly higher than that in the foreign cohort.
Overall, the 4S-J-16 has good internal consistency, test-retest reliability, and construct validity with a three-factor structure of self-stigma in Japanese AWS. The findings suggest that Japanese cultural background increases the stigma scores, thereby enabling us to briefly assess the psychosocial issues of AWS.
本研究旨在开发一个简短的日语版口吃者自我污名量表（4S），该量表以自我报告的形式评估口吃成年人（AWS）的自我污名，并评估其心理测量特性、信度和效度。
通过正向-反向翻译过程将原始的 4S 量表翻译成日语（4S-J）后，对 123 名日本口吃者进行了测试。通过因子分析和删除对原始因子负荷较低的项目，开发了 4S-J 的简短版本。通过计算内部一致性和重测信度来验证信度。参与者还完成了日本翻译版的罗森伯格自尊量表、一般自我效能感量表和主观幸福感量表，以验证结构效度。作为二次分析，然后将我们关于 4S 简短版本心理特性的结果与来自其他国家的研究结果进行比较。
选择了 16 个项目作为量表的简短版本（4S-J-16），验证了 4S 的原始结构。我们获得了良好的内部一致性和重测信度。关于结构效度，我们的结果与其他选定量表的相关性相似。日本队列中污名量表的所有分数值均明显高于国外队列。
总体而言，4S-J-16 在日本 AWS 中具有良好的三因素结构的内部一致性、重测信度和结构效度。研究结果表明，日本文化背景增加了污名分数，从而使我们能够简要评估 AWS 的心理社会问题。
