To verify the Brief Psychosomatic Symptom Scale (BPSS) among patients with psychosomatic-related disorders in general hospitals and determine the threshold of BPSS.
The BPSS is a shortened 10-item version of the psychosomatic symptoms scale (PSSS). Data from 483 patients and 388 healthy controls were included for psychometric analyses. Internal consistency, construct validity, and factorial validity were verified. The threshold of BPSS in distinguishing psychosomatic patients from healthy controls were determined using receiver operating characteristic (ROC) curve analysis. The ROC curve of the BPSS was compared with that of the PSSS and patient health questionnaire-15 (PHQ-15) by using Venkatraman's method with 2000 times Monte-Carlo simulations.
The reliability of the BPSS was good with Cronbach's α of 0.831. BPSS was significantly correlated with PSSS (r = 0.886, P < 0.001), PHQ-15 (r = 0.752, P < 0.001), PHQ-9 (r = 0.757, P < 0.001) and GAD-7 (r = 0.715, P < 0.001), which indicated good construct validity. ROC analyses demonstrated that the AUC of the BPSS was comparable with that of PSSS. The gender-specific threshold of BPSS was determined as ≥8 in males and ≥ 9 in females.
The BPSS is a brief and validated instrument for screening common psychosomatic symptoms.
验证Brief Psychosomatic Symptom Scale（BPSS）在综合医院心身相关障碍患者中的适用性，并确定 BPSS 的截断值。
BPSS 是心身症状量表（PSSS）的 10 项简短版本。纳入 483 例患者和 388 例健康对照者的数据进行心理测量学分析。验证内部一致性、结构效度和因子效度。采用受试者工作特征（ROC）曲线分析确定 BPSS 区分心身患者与健康对照者的截断值。使用 Venkatraman 法和 2000 次蒙特卡罗模拟比较 BPSS、PSSS 和患者健康问卷-15（PHQ-15）的 ROC 曲线。
BPSS 的信度良好，Cronbach's α 为 0.831。BPSS 与 PSSS（r=0.886，P<0.001）、PHQ-15（r=0.752，P<0.001）、PHQ-9（r=0.757，P<0.001）和 GAD-7（r=0.715，P<0.001）显著相关，表明具有良好的结构效度。ROC 分析表明，BPSS 的 AUC 与 PSSS 相当。确定 BPSS 的性别特异性截断值为男性≥8，女性≥9。
BPSS 是一种简短且有效的筛查常见心身症状的工具。
