The new DSM-5 Somatic Symptom Disorder (SSD) emphasizes the importance of psychological processes related to somatic symptoms in patients with somatoform disorders. To address this, the Somatic Symptoms Experiences Questionnaire (SSEQ), the first self-report scale that assesses a broad range of psychological and interactional characteristics relevant to patients with a somatoform disorder or SSD, was developed. This prospective study was conducted to validate the SSEQ.
The 15-item SSEQ was administered along with a battery of self-report questionnaires to psychosomatic inpatients. Patients were assessed with the Structured Clinical Interview for DSM-IV to confirm a somatoform, depressive, or anxiety disorder. Confirmatory factor analyses, tests of internal consistency and tests of validity were performed.
Patients (n=262) with a mean age of 43.4 years, 60.3% women, were included in the analyses. The previously observed four-factor model was replicated and internal consistency was good (Cronbach's α=.90). Patients with a somatoform disorder had significantly higher scores on the SSEQ (t=4.24, p<.001) than patients with a depressive/anxiety disorder. Construct validity was shown by high correlations with other instruments measuring related constructs. Hierarchical multiple regression analyses showed that the questionnaire predicted health-related quality of life. Sensitivity to change was shown by significantly higher effect sizes of the SSEQ change scores for improved patients than for patients without improvement.
The SSEQ appears to be a reliable, valid, and efficient instrument to assess a broad range of psychological and interactional features related to the experience of somatic symptoms.
新版《精神疾病诊断与统计手册》第五版（DSM-5）中的躯体症状障碍（SSD）强调了与躯体形式障碍患者躯体症状相关的心理过程的重要性。为解决这一问题，开发了躯体症状体验问卷（SSEQ），这是首个用于评估与躯体形式障碍或SSD患者相关的广泛心理和互动特征的自我报告量表。本前瞻性研究旨在验证SSEQ。
对心身科住院患者发放包含15个条目的SSEQ以及一系列自我报告问卷。采用《精神疾病诊断与统计手册》第四版（DSM-IV）的结构化临床访谈对患者进行评估，以确认是否患有躯体形式障碍、抑郁症或焦虑症。进行了验证性因素分析、内部一致性检验和效度检验。
分析纳入了平均年龄为43.4岁的患者（n = 262），其中60.3%为女性。先前观察到的四因素模型得到重复，内部一致性良好（Cronbach'sα = 0.90）。躯体形式障碍患者在SSEQ上的得分显著高于抑郁/焦虑症患者（t = 4.24，p <.001）。与测量相关结构的其他工具高度相关，表明了结构效度。分层多元回归分析表明，该问卷可预测健康相关生活质量。改善患者的SSEQ变化得分的效应量显著高于未改善患者，表明了对变化的敏感性。
SSEQ似乎是一种可靠、有效且高效的工具，可用于评估与躯体症状体验相关的广泛心理和互动特征。
