The Palliative Care Self-Efficacy Scale (PCSE) is a valid instrument in English for assessing healthcare professionals' self-efficacy in providing palliative care; it has not been translated into Swedish. The aim of this study was to describe the translation, cultural adaptation, and content-validation process of the PCSE scale. In this study, forward and backward translations, pretesting including an expert panel (n = 7), and cognitive interviewing with possible healthcare professionals (physicians, nurses, and assistant nurses) (n = 10) were performed. Experts in palliative care rated items on a Likert scale based on their understandability, clarity, sensitivity, and relevance. The item-level content validity index (I-CVI) and modified kappa statistics were calculated. Healthcare professionals were interviewed using the think-aloud method. The translation and validation process resulted in the final version of the PCSE scale. The average I-CVI for sensitivity was evaluated and approved. Most of the items were approved for clarity, some items lacked understandability, but a majority of the items were considered relevant. The healthcare professionals agreed that the items in the questionnaire evoked emotions, but were relevant for healthcare professionals. Thus, the Palliative Care Self-Efficacy scale is relevant for assessing healthcare professionals' self-efficacy in palliative care in a Swedish care context. Further research using psychometric tests is required.
