The Quality of Life of persons with significant support needs: content validity of the Portuguese version of Escala de San Martín

António Rodrigo, Sofia Santos, Fernando Gomes


Introduction: The measurement of the quality of life (QoL) is only now being used in Portugal in the intellectual disabilities (ID) field. Moreover, there is no instrument addressed to people with ID with significant support needs (SSN). The Escala San Martin was translated to Portuguese (PESM), according to the international guidelines for cross-cultural studies. Objective: The purpose of this study is the analysis of the content validity of the Portuguese version of the instrument. Methods: Measuring and reporting instruments’ content validity and Cohen’s Kappa is one of the first steps to accomplish in a validation process. PESM was applied to 52 adults (above 18 years) with ID, institutionalized and with great support needs. Results: Content Validity Indexes were determined and all items were relevant, with moderate agreement between experts. Conclusion: Findings pointed out the relevance of the items, indicating that PESM’s content is valid and adequate for the assessment of QoL of persons with low functioning levels.
