Abstract：
BACKGROUND: Foot problems are one of the main causes of seeing a doctor. According to the World Health Organization\'s definition of health, the healthcare system must consider patients\' quality of life as an important entity. In this regard, many tools have been developed to evaluate patients\' opinions about their health status. The purpose of the present study is to evaluate the validity and reliability of the Persian version of the Foot Self-Assessment Questionnaire (SAFE-Q) in patients with foot orthopedic problems.
METHODS: 215 people aged 17-60 years with orthopedic foot problems were included in this cross-sectional study. The Spearman correlation coefficient of SAFE-Q questionnaires versus Foot Function Index (FFI) questionnaire was evaluated for the convergent validity. Forty-three people randomly completed SAFE-Q again one week later. Intraclass correlation coefficient (ICC) and Cronbach\'s alpha was calculated to evaluate the test-retest reliability and internal consistency of the SAFE-Q, respectively.
RESULTS: A strong relationship was found between the SAFE-Q total score and other scales with FFI questionnaire (r = 0.52 to 0.87). ICC test-retest reliability and Cronbach\'s alpha were 0.981 and 0.98 for SAFE-Q, respectively.
CONCLUSIONS: The results indicate that the Persian version of the SAFE-Q questionnaire has acceptable validity and reliability and can be used to assess the health status and quality of life of Persian speakers with orthopedic foot problems.

摘要：
背景：足部问题是看医生的主要原因之一。根据世界卫生组织对健康的定义,医疗保健系统必须将患者的生活质量视为一个重要实体。在这方面,已经开发了许多工具来评估患者对其健康状况的看法。本研究的目的是评估波斯语版本的足部自我评估问卷（SAFE-Q）在足部骨科问题患者中的有效性和可靠性。
方法：215名年龄在17-60岁的骨科足部问题患者被纳入本横断面研究。评价了SAFE-Q问卷与足部功能指数(FFI)问卷的Spearman相关系数的收敛效度。一周后，有43人随机再次完成了SAFE-Q。计算了组内相关系数（ICC）和Cronbachα，以评估SAFE-Q的重测可靠性和内部一致性，分别。
结果：发现SAFE-Q总分与FFI问卷的其他量表之间存在很强的关系（r=0.52至0.87）。SAFE-Q的ICC重测可靠性和Cronbachα分别为0.981和0.98，分别。
结论：结果表明，波斯语版本的SAFE-Q问卷具有可接受的有效性和可靠性，可用于评估波斯语患者的健康状况和生活质量。
