Information concealment in palliative patients: Development and pilot study of a new scale for caregivers

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.
