Abstract

This study validated the Self-Efficacy for Managing Chronic Diseases Scale (SEMCD-6) in the Brazilian context and investigated its association with anxiety and depression. The sample included 412 adults with chronic diseases (mean age = 48.1 years; 92 % women; 65 % with multimorbidity). A confirmatory factor analysis supported the unidimensional structure, with excellent fit indices (χ²/df = 2.211; CFI = .996; RMSEA = .054), factor loadings between .752 and .925, and satisfactory internal consistency (α = .942; ω = .943). Convergent validity was also confirmed (AVE = .733; CR = .950). Self-efficacy was negatively correlated with depressive (r = -.346) and anxious symptoms (r = -.362). Participants with moderate to severe depressive and anxious symptomatology showed significantly lower self-efficacy scores. The SEMCD-6 demonstrated adequate psychometric properties in a sample of Brazilian patients, serving as a valuable tool for identifying patients with low self-efficacy in managing chronic diseases, thereby enabling preventive interventions and better allocation of mental health resources. Future studies should verify this structure in more representative samples of the Brazilian population.
