Cultural Adaptation and Testing of the Italian Version of the Edmonton Functional Assessment Tool-2 (EFAT2-I)

Description

Background: Physiotherapy in Palliative Care (PC) is effective in the management of a series of respiratory, circulatory and motor symptoms, and often has a positive impact on the patient's mood. The Edmonton Functional Assessment Tool (EFAT) is the only existing validated tool specifically designed for functional assessment in PC, and its use has been recommended in clinical practice. To date, no Italian version of the tool has been validated. The aim of this study was to translate, cross-culturally adapt, and evaluate the psychometric properties of the Italian version of the EFAT2. Method: After receiving formal permission from the author, Beaton guidelines for cross-cultural adaptation were followed, namely: (1) forward translation; (2) a multidisciplinary focus group (including 4 physiotherapists, 1 physician, 3 nurses, 1 occupational therapist, 1 psychologist) to assess semantic, idiomatic, experiential, and conceptual equivalence; (3) backward translation. The Content Validity Index (CVI) was used to assess content validity of the tool. Construct and concurrent validity were also evaluated. To evaluate the reliability of the EFAT2-I, reliability was measured using Cronbach alfa, item-total correlation, and Cohen's Kappa. Results: 119 patients admitted to a Palliative Care Unit (Italy) agreed to participate in the study. The EFAT2-I mean score was 11.3, ranging from 0 to 30. Very good CVI scores were achieved, both in terms of single item validity (I-CVI) and of whole scale validity (S-CVI). Positive results were obtained from construct, concurrent validity assessment and measures of reliability. Discussion: The EFAT2-I showed good psychometric properties and can be used as a rehabilitation assessment tool in palliative care settings. The validation of the Italian version will allow comparison of different centres and palliative care facilities on national and international levels.
