Measuring spiritual well-being in Brazilian adolescents with chronic illness using the FACIT-Sp-12: age adaptation of the self-report version, development of the parental-report version, and validation. journal of religion and health. Journal of Religion and Health, 58(6), 2219-2240. https://doi.org/10.1007/s10943-019-00901-y0022-419710.1007/s10943-019-00901-yhttps://academica-e.unavarra.es/handle/2454/52910Spiritual well-being is a major issue in health care, but instruments for measuring this construct in adolescents are lacking. This study adapted the 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp-12) for use with Brazilian adolescents with chronic diseases and developed a parental observer-rated version, using an expert panel, back-translation, and cognitive interviews with 72 participants. The psychometric properties of both versions were verified with two- and three-factor models by testing with 212 participants. The self- and parental-reported versions showed face validity, content validity, and acceptable levels of internal consistency for the overall scale and the two-factor model. The convergent validity was satisfactory for most items in both two- and three-factor models, but there was a lack of discrimination in the three-factor model using multitrait-multimethod analysis. This study presents the first instrument to assess the spiritual well-being of adolescents from their point of view and to allow their parents to serve as evaluators. However, we recommend further psychometric testing of the self- and parental-report scales to assess spiritual well-being in adolescents with chronic diseases in Brazil.application/pdfeng© Springer Science+Business Media, LLC, part of Springer Nature 2019Validation studiesPsychometricsAdolescentsParentsProxySpiritualitySpiritual well-beinginfo:eu-repo/semantics/article2025-01-14info:eu-repo/semantics/openAccess
