Abstract

Objective

This study evaluated the reliability and validity of the Japanese version of the Somatic Symptom Disorder–B Criteria Scale (J-SSD-12), which assesses psychological features of somatic symptom disorder (SSD) as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Criterion B.

Methods

A total of 1148 Japanese internet panel participants completed the J-SSD-12, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 scale (GAD-7), Patient Health Questionnaire-15 (PHQ-15), and Short Health Anxiety Inventory (SHAI). Confirmatory factor analysis (CFA) examined factorial validity, with a correlated error specified between Items 7 and 10 for their shared negative wording and emphasis on others' evaluations. Reliability was assessed using test–retest correlations, intraclass correlation coefficients (ICCs), and Cronbach's alpha (α). Convergent validity was primarily evaluated through correlations with four additional scales.

Results

The mean participant age was 48.8 years (SD = 17.3), and 54.6 % were female. The scree plot and high inter-factor correlations suggested a possible unidimensional structure; however, the one-factor model did not achieve satisfactory fit (Comparative Fit Index [CFI] = 0.94, Root Mean Square Error of Approximation [RMSEA] = 0.107). In contrast, the three-factor structure showed acceptable fit on CFI (0.96) and Tucker–Lewis Index (TLI; 0.95), while RMSEA (0.091) indicated only marginal fit. The J-SSD-12 demonstrated good test–retest reliability (correlation coefficient [r] = 0.72; ICCs = 0.72–0.84) and excellent internal consistency (α = 0.95). Moderate correlations with the PHQ-9, GAD-7, PHQ-15, and SHAI (r = 0.60–0.66) supported convergent validity.

Conclusion

The J-SSD-12 provides evidence supporting the reliability and validity of assessing SSD-related psychological features in a Japanese sample. Despite certain limitations, this measure appears useful for both research and potential clinical applications.

日本版躯体症状障碍b标准量表（J-SSD-12）的信度与验证。

目的：本研究评估日本版躯体症状障碍- b标准量表（J-SSD-12）的信度和效度，该量表评估《精神障碍诊断与统计手册》第五版（DSM-5）标准b定义的躯体症状障碍（SSD）的心理特征。共有1148名日本互联网小组参与者完成了J-SSD-12、患者健康问卷-9 （PHQ-9）、广泛性焦虑障碍量表-7 （GAD-7）、患者健康问卷-15 （PHQ-15）和短期健康焦虑量表（SHAI）。验证性因子分析（CFA）检查了因子效度，在项目7和项目10之间指定了一个相关误差，因为它们的共同负面措辞和强调他人的评价。信度评估采用重测相关性、类内相关系数（ICCs）和Cronbach’s alpha （α）。收敛效度主要通过与四个附加量表的相关性来评估。结果：参与者平均年龄为48.8岁（SD = 17.3），女性占54.6%。屏幕图和高因子间相关性提示可能存在单维结构；然而，单因素模型没有达到令人满意的拟合（比较拟合指数[CFI] = 0.94，近似均方根误差[RMSEA] = 0.107）。相比之下，三因素结构在CFI（0.96）和Tucker-Lewis指数（TLI; 0.95）上的拟合是可以接受的，而RMSEA（0.091）仅显示边际拟合。J-SSD-12具有良好的重测信度（相关系数[r] = 0.72; ICCs = 0.72 ~ 0.84）和良好的内部一致性（α = 0.95）。与PHQ-9、GAD-7、PHQ-15和SHAI的中度相关性（r = 0.60-0.66）支持收敛效度。结论：J-SSD-12在日本样本中提供了支持评估ssd相关心理特征的信度和效度的证据。尽管有一定的局限性，但这一措施似乎对研究和潜在的临床应用都很有用。

期刊介绍： General Hospital Psychiatry explores the many linkages among psychiatry, medicine, and primary care. In emphasizing a biopsychosocial approach to illness and health, the journal provides a forum for professionals with clinical, academic, and research interests in psychiatry''s role in the mainstream of medicine.
