BACKGROUND This study examined the prevalence of somatization disorder in Urological Chronic Pelvic Pain Syndrome (UCPPS) and the utility of two self-report symptom screening tools for assessment of somatization in patients with UCPPS. METHODS The study sample included 65 patients with UCPPS who enrolled in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Study at Washington University. Patients completed the PolySymptomatic PolySyndromic Questionnaire (PSPS-Q) (n = 64) and the Patient Health Questionnaire-15 Somatic Symptom Severity Scale (PHQ-15) (n = 50). Review of patient medical records found that only 47% (n = 30) contained sufficient documentation to assess Perley-Guze criteria for somatization disorder. RESULTS Few (only 6.5%) of the UCPPS sample met Perley-Guze criteria for definite somatization disorder. Perley-Guze somatization disorder was predicted by definite PSPS-Q somatization with at least 75% sensitivity and specificity. Perley-Guze somatization disorder was predicted by severe (> 15) PHQ-15 threshold that had > 90% sensitivity and specificity but was met by only 16% of patients. The moderate (> 10) PHQ-15 threshold had higher sensitivity (100%) but lower specificity (52%) and was met by 52% of the sample. CONCLUSIONS The PHQ-15 is brief, but it measures symptoms constituting only one dimension of somatization. The PSPS-Q uniquely captures two conceptual dimensions inherent in the definition of somatization disorder, both number of symptoms and symptom distribution across multiple organ systems, with relevance for UCPPS as a syndrome that is not just a collection of urological symptoms but a broader syndrome with symptoms extending beyond the urological system.

评估泌尿科慢性盆腔痛综合征的躯体化。

背景技术这项研究检查了泌尿科慢性盆腔疼痛综合征（UCPPS）中的躯体化障碍的患病率，以及两种自我报告症状筛查工具对UCPPS患者的躯体化评估的实用性。方法该研究样本包括65名UCPPS患者，他们参加了华盛顿大学的慢性骨盆痛研究（MAPP）研究的多学科研究。患者完成了《多症状综合症问卷》（PSPS-Q）（n = 64）和《患者健康状况问卷-15躯体症状严重程度量表》（PHQ-15）（n = 50）。对患者医疗记录的审查发现，只有47％（n = 30）包含足够的文献来评估Perley-Guze的躯体化疾病标准。结果UCPPS样本中只有极少数（仅6.5％）满足Perley-Guze明确的躯体化疾病标准。Perley-Guze躯体化障碍是通过明确的PSPS-Q躯体化预测的，敏感性和特异性至少为75％。Perley-Guze躯体化障碍是通过严重（> 15）PHQ-15阈值预测的，该阈值具有> 90％的敏感性和特异性，但只有16％的患者可以满足。中度（> 10）PHQ-15阈值具有较高的灵敏度（100％）但较低的特异性（52％），且52％的样品可以满足。结论PHQ-15是简短的，但它只能测量构成躯体化一维的症状。PSPS-Q独特地捕捉了躯体化障碍定义中固有的两个概念维度，即症状的数量和症状在多个器官系统中的分布，
