Previous studies on palliative care have assessed the phenomenon of Information Concealment (IC), confirmed its relevance and emphasised the need to have a scale for its assessment. The aim of this study was to design and validate such an instrument. The sample comprised 150 palliative caregivers (23 men and 127 women). The dimensionality of the items of the Information Concealment Scale for Caregivers (ECOI) was assessed using Exploratory Factor Analysis and an optimal implementation of parallel analysis. Reliability and criterion validity were analysed using sample data. The ECOI comprises three factors: Concealment or dissimulation about the disease, misrepresentation of the real situation and control of the information. The scale has excellent reliability and shows criterion validity. Therefore, the ECOI is a reliable and valid instrument to objectively measure IC among Spanish caregivers in palliative care settings.

姑息治疗患者的信息隐藏：护理人员新量表的开发和试点研究

先前关于姑息治疗的研究评估了信息隐藏 (IC) 现象，证实了其相关性并强调需要对其进行评估的量表。本研究的目的是设计和验证这样的仪器。该样本包括 150 名姑息治疗护理人员（23 名男性和 127 名女性）。使用探索性因素分析和平行分析的最佳实施评估看护者信息隐藏量表 (ECOI) 项目的维度。使用样本数据分析可靠性和标准有效性。ECOI包括三个因素：对疾病的隐瞒或掩饰、对真实情况的歪曲和对信息的控制。该量表具有良好的信度和效标效度。所以，
