Translation, adaptation, and validation of the Self-efficacy in Palliative Care scale (SEPC) for use in Swedish healthcare settings

Abstract

Background: One challenge for healthcare professionals when delivering palliative care can be their lack of confidence. The Self-efficacy in Palliative Care Scale (SEPC) is considered a valid and reliable assessment scale to evaluate confidence when delivering palliative care. Currently, there is not a reliable instrument aimed to measure healthcare professionals’ confidence in palliative care in Swedish. Therefore, this study aimed to translate, culturally adapt, and validate the SEPC-scale for use in a Swedish healthcare context. Methods: This study applied the World Health Organization’s (WHO) guidelines for translating and adapting instruments, using forward and back-translation, an expert panel, and cognitive interviews. Swedish experts in palliative care (n = 6) assessed the Swedish version of the SEPC-scale based on its relevance, understandability, clarity, and sensitivity on a Likert scale. Methods involved calculation of content validity index (CVI) with modified kappa statistics and cognitive interviewing with healthcare professionals (n = 10) according to the “think-aloud” method. Results: Calculation of I-CVI (Item-CVI) showed that the Swedish SEPC-scale was considered relevant but needed some modifications to improve its understandability and clarity. The experts recognized an absence of precision in some items that affected clarity and understanding. Likewise, the healthcare professionals highlighted some challenges with understandability and clarity. They indicated that the scale was relevant, but a few items needed adjustment to fit a broader range of healthcare professionals. Items that referred to death and dying could be sensitive but were considered relevant. Conclusions: The SEPC-scale is considered valid for use in Swedish healthcare practice, for a broad range of healthcare professionals, and for diagnoses other than cancer. This study shows that cultural adaptation is necessary for establishing relevance and enabling acceptance to various healthcare professionals and contexts in the target country.
