We aimed to psychometrically validate the Japanese version of the Somatic Symptom Scale-8 (SSS-8) in Japanese individuals.
Data were collected from Japanese individuals aged 20-64years, who were recruited online, in February 2015. The scale reliability and validity were analyzed.
Data from 52,353 individuals were analyzed. Cronbach's alpha for the assessment of internal consistency reliability was 0.86 for the total score. The concurrent validity results showed strong correlations with three domains of the Profile of Mood States-Brief form (ρ=0.51-0.61) and the EuroQol 5 Dimension (ρ=-0.54). The known-group validity results indicated a linear trend in the severity of depression stratified using the Patient Health Questionnaire-2 (Jonckheere-Terpstra test, p<0.001). Regarding convergent and discriminant validities, all items correlated most strongly with their own domains (coefficients≥0.5), except for one item (headaches). Scores on perceived stress, pain, and general health differed across five SSS-8 severity groups (Steel-Dwass test, p<0.001), expect for one group pair in health.
The Japanese version of the SSS-8 was valid with good internal consistency. This questionnaire could help detect somatic symptom burdens of chronic and severe musculoskeletal pain for primary prevention.
我们旨在对日本版的躯体症状量表-8（SSS-8）在日本人群中进行心理测量学验证。
2015年2月，从通过网络招募的20至64岁日本人群中收集数据。对该量表的信度和效度进行分析。
分析了52353人的数据。用于评估内部一致性信度的Cronbach's α系数，总分是0.86。同时效度结果显示，与简明心境状态剖面图的三个维度（ρ=0.51 - 0.61）以及欧洲五维健康量表（ρ=-0.54）有很强的相关性。已知组效度结果表明，使用患者健康问卷-2进行分层的抑郁严重程度呈线性趋势（Jonckheere-Terpstra检验，p<0.001）。关于聚合效度和区分效度，除了一项（头痛）外，所有项目与其自身维度的相关性最强（系数≥0.5）。在五个SSS-8严重程度组中，感知压力、疼痛和总体健康得分存在差异（Steel-Dwass检验，p<0.001），健康方面有一组配对情况除外。
日本版的SSS-8有效，具有良好的内部一致性。该问卷有助于检测慢性和严重肌肉骨骼疼痛的躯体症状负担，用于一级预防。
