Assessment tools are commonly used in different fields of health to assist in the diagnosis, the evaluation of the response to treatment, the measurement of quality of life and the establishment of the prognosis.
Translate, culturally adapt and perform the psychometric validation of the Somatic Symptom Scale (SSS-8) for use in the Brazilian population.
Cross-cultural adaptation followed a combination of guidelines and for psychometric evaluation a sample of 300 patients was recruited. All recommended measurement properties by the Consensus-based Standards for the selection of health status Measurement Instruments were evaluated, including analysis by an expert committee and analysis by the target public. The Skindex-16 was used for the evaluation of convergent validity and Cronbach's alpha was used for the determination of the internal consistency of the translated version of the SSS-8.
The final version received approval from five experts and the agreement index was 100% for all items. During the pretest, the scale was administered to 300 patients with psoriasis and none of the items needed to be altered. A moderate correlation was found between the Skindex-16 and SSS-8-BRA. In the analysis of internal consistency, Cronbach's alpha for the SSS-8-BRA was 0.81.
The SSS-8 is a valid and reliable tool for the assessment of somatic symptoms in the Brazilian population.

将躯体症状量表（SSS-8）翻译、文化调适并进行心理计量学验证，以便在巴西人群中使用。
跨文化调适遵循了一系列指南，对于心理计量学评估，招募了 300 名患者的样本。评估了共识标准中推荐的所有测量特性，包括专家委员会的分析和目标人群的分析。Skindex-16 用于评估收敛效度，Cronbach's alpha 用于确定 SSS-8 翻译版本的内部一致性。
最终版本获得了五位专家的认可，所有项目的一致性指数均为 100%。在预测试期间，该量表被用于 300 名银屑病患者，没有需要改变的项目。Skindex-16 和 SSS-8-BRA 之间存在中度相关性。在内部一致性分析中，SSS-8-BRA 的 Cronbach's alpha 为 0.81。
SSS-8 是评估巴西人群躯体症状的有效且可靠的工具。
