AbstractIntroductionThe exploration of conceptual equivalence within the process of the cross‐cultural adaptation of tools is usually neglected as it generally assumed that the theoretical construct of a tool is conceptualized in the same way in both the original and target culture. This article attempts to throw light on the contribution of the evaluation of conceptual equivalence to the process of adaptation, and for tool development. To illustrate this premise, the example of the cross‐cultural adaptation of the Patients' Perception of Feeling Known by their Nurses (PPFKN) Scale is presented.DesignAn adapted version of the Sousa and Rojjanasrirat (Journal of Evaluation in Clinical Practice, 2011, 17(2), 268–274) guidelines was used to translate and culturally adapt the PPFKN Scale to Spanish language and culture. A qualitative descriptive study was added to the traditional process of translation and pilot study to explore the concept in the target culture and recognize conceptual equivalence.MethodsExperts in the tool concept, bilingual translators and the author of the tool participated in the translation of the original tool into Spanish. A pilot study of the Spanish version with a sample of 44 patients and a panel of six experts from different fields evaluated its clarity and relevance. In addition, seven patients participated in a descriptive qualitative study using semi‐structured individual interviews to explore the phenomenon in the new culture. A content analysis following the Miles, Huberman & Saldaña (Qualitative data analysis, a methods sourcebook, 2014) approach was used to analyze qualitative data.ResultsThe cross‐cultural translation and adaptation of the PPFKN scale into Spanish required a thorough revision. More than half of the items needed discussions to reach consensus regarding the most appropriate Spanish term. In addition, the study confirmed the four attributes of the concept identified in the American context and allowed for new insights within those attributes to appear. Those aspects reflected characteristics of the phenomenon of being known in the Spanish context and were added to the tool in the format of 10 new items.ConclusionsA comprehensive cross‐cultural adaptation of tools should incorporate, together with the study of linguistic and semantic equivalence, the analysis of the conceptual equivalence of the phenomenon in both contexts. The identification, acknowledgment and study of the conceptual differences between two cultures in relation to a phenomenon becomes an opportunity for deeper study of the phenomenon in both cultures, for understanding of their richness and depth, and for the proposal of changes that may enhance the content validity of the tool.Clinical relevanceThe evaluation of conceptual equivalence of tools within the process of cross‐cultural adaptation will make it possible for target cultures to rely on tools both theoretically sound and significant. Specifically, the cross‐cultural adaptation of the PPFKN scale has facilitated the design of a Spanish version of the tool that is linguistically, semantically and theoretically congruent with Spanish culture. The PPFKN Scale is a powerful indicator that evidences nursing care contribution to the patient's experience.
