Adaptação cultural, validade e fiabilidade da escala pessoal de resultados-crianças e jovens

The present research presents the results of an initial study that aims to analyze the cross-cultural adaptation of the Personal Outcomes Scale-Children and Adolescents (POS-C), as well as to examine its validity and reliability. This scale assesses the Quality of Life (QOL) of children and adolescents with Intellectual Disability (ID). Of the several samples involved in the research, it is stressed that the final sample included 54 children and adolescents with ID and 54 education support staff. The research started with the application of the cross-cultural adaptation’ guidelines. The results of the Content Validity Index (CVI) of each item, the scale CVI-universal agreement, the scale CVI average and the Cohen’s kappa scores supported the content validity, and the Pearson’s correlations confirmed the construct validity of the POS-C. The test-retest, the internal consistency and the inter-rater reliability supported the reliability of the tool. The different psychometric coefficients demonstrate that this scale may be advantageous to assess the QOL of children and adolescents with ID, as well as to design the intervention programs of those students in inclusive contexts of learning.
