The Trust in Oncologist Scale (TiOS) is an 18-item questionnaire aimed to assess the cancer patients' trust in their oncologist and has been validated in Dutch and English language. This study aims to validate the Italian version of the TiOS (IT-TiOS) and the TiOS-Short Form (IT-TiOS-SF).
The IT-TiOS was administered to 194 patients recruited in an Italian oncology department from April to December 2018. Data collected included socio-demographic data, health and clinical information, satisfaction with the most recent oncology visit and trust in the regional healthcare system. Internal consistency, test-retest reliability, convergent and the structural validity of both the full and short form were tested.
Factor analyses indicated that neither four-factor nor one-factor models of the full scale were acceptable. However, confirmatory factor analysis supported the one-dimensionality of the IT-TiOS-SF, and internal consistency assessed with Cronbach's alpha was 0.88. Mean scores on the IT-TiOS-SF correlated with satisfaction with the oncologist (rs = 0.64) and willingness to recommend the oncologist to others (rs = 0.67), confirming good construct validity.
The IT-TiOS-SF demonstrates good psychometric properties and can be used to assess trust for both clinical and research purposes.
信任肿瘤学家量表（TiOS）是一个由 18 个项目组成的问卷，旨在评估癌症患者对其肿瘤学家的信任程度，并已在荷兰语和英语中得到验证。本研究旨在验证 TiOS 的意大利语版本（IT-TiOS）和 TiOS 简化版（IT-TiOS-SF）。
2018 年 4 月至 12 月，在意大利的一个肿瘤学部门招募了 194 名患者，他们接受了 IT-TiOS 的测试。收集的数据包括社会人口统计学数据、健康和临床信息、对最近的肿瘤学就诊的满意度以及对区域医疗保健系统的信任度。测试了完整和简化形式的内部一致性、重测信度、收敛性和结构有效性。
因子分析表明，完整量表的四因素或单因素模型均不可接受。然而，验证性因子分析支持了 IT-TiOS-SF 的一维性，Cronbach's alpha 评估的内部一致性为 0.88。IT-TiOS-SF 的平均得分与对肿瘤学家的满意度（rs=0.64）和向他人推荐肿瘤学家的意愿（rs=0.67）相关，证实了良好的结构有效性。
IT-TiOS-SF 具有良好的心理测量学特性，可用于评估临床和研究目的的信任。
