Two researchers conducted independent searches on five different electronic databases: PubMed/MEDLINE, Embase, SciELO, LiLACS and Web of Science. Studies were selected that covered cross-cultural adaptation methodology and validation in Brazil with type 1 and type 2 diabetes patients of any age. After reading the full-text articles, data related to psychometric characteristics were extracted from each study selected. Reliability was assessed with Cronbach’s α (Cα). The initial searches identified 2,211 studies. After exclusions, 26 were included, covering a total of 31 questionnaires. Questionnaires were grouped into 11 domains based on their main focus of interest: adherence (n = 8), quality of life (n = 7), diabetes knowledge (n = 3), hypoglycemia (n = 3), self-efficacy (n = 3), satisfaction with pharmaceutical services (n = 1), emotional stress (n = 2), hope (n = 1), attitude towards diabetes (n = 1), perception of disease severity (n=1), and risk of developing diabetes (n = 1). This study identified and reviewed all of the diabetes-specific questionnaires that have been validated for Brazilian Portuguese, which should facilitate selection of the most appropriate instrument for each domain of interest in future research and clinical settings.
