Introduction: Self-efficacy is an important concept associated with positive health outcomes in pediatric chronic respiratory conditions. However, to date, there is no validated instrument for the Brazilian population to estimate self-efficacy in various types of chronic respiratory conditions in childhood and adolescence. Objective: To cross-culturally adapt and evaluate the psychometric properties of the Brazilian version of the Pediatric Rating of Chronic Illness Self-Efficacy (PRCISE-Br) for children and adolescents with chronic respiratory conditions. Methods: Exploratory methodological study approved by the research ethics committee of UFRN/FACISA (No. 6.061.966). The cross-cultural adaptation protocol involved 6 stages: translation, synthesis of translations, back-translation, expert committee, pre-test, and submission of documents to the original author. During the pre-test phase, in-depth interviews were conducted to complement the assessment of interviewees' comprehension. Psychometric properties were assessed in a sample of children and adolescents of both sexes, aged 7 to 18 years, with a clinical diagnosis of asthma, cystic fibrosis, or other isolated chronic respiratory conditions. Psychometric tests were used to estimate content and construct validity (structural, convergent, divergent), reliability (internal consistency and test-retest), and floor and ceiling effects. Results: The cross-cultural adaptation of PRCISE-Br involved the inclusion of instructions and statements instead of questions, aiming to facilitate understanding among the target audience. All items were adequately understood and demonstrated satisfactory content validity (CVI ≥ 0.78). The sample for evaluating psychometric properties consisted of 36 individuals with a median age of 11.00 [9.00 – 14.75] years and clinical diagnoses of cystic fibrosis (66.67%) and asthma (33.33%). In the exploratory factor analysis, the structure of PRCISE-Br was obtained by determining 1 fixed factor, which explained 23.58% of the total variance. The fit indices obtained in the confirmatory analysis using SPSS Amos (χ2 = 204.083; df = 90, χ2/df = 2.267; p < 0.001; CFI = 0.288; TLI = 0.169; GFI = 0.613; SRMR = 1.062; RMSEA = 0.190) indicated that the model was not considered entirely adequate. PRCISE-Br showed moderate correlations with another self-efficacy instrument (EAGP; r = 0.486; p = 0.003) and with a quality-of-life scale (PedsQL™ 4.0; r = 0.604; p < 0.001). No significant correlations were found between self-efficacy and the number of hospitalizations (r = -0.301; p = 0.075) and emergency department visits (r = -0.115; p = 0.504) in the last 12 months. PRCISE-Br demonstrated good reliability with a Cronbach's alpha coefficient of 0.71 and ICC of 0.613 (95% CI = -0.036 – 0.855; p = 0.029). A ceiling effect was observed (41.67%), and no floor effects were found in the study sample. Conclusion: The PRCISE-Br has been cross-culturally adapted and is semantically equivalent to the original version. The psychometric properties demonstrate that the instrument yields reliable and valid measures and can be used in research and clinical practice to estimate self-efficacy in children and adolescents with chronic respiratory conditions.
