AB  - BACKGROUND: Health-related control and self-efficacy beliefs can be assessed in 
      the general population using Multidimensional Health Locus of Control-A subscales 
      (MHLC-A) and the General Self-Efficacy Scale (GSES), respectively. OBJECTIVE: To 
      test construct validity, internal consistency, reliability (test-retest) and 
      ceiling and floor effects of Portuguese-Brazil versions of MHLC-A and GSES. 
      METHOD: Civil servants (N=2901) enrolled in a large Brazilian cohort were 
      included. A new version of the GSES was produced (GSES-Brazil). Procedures for 
      cross-cultural adaptation and testing of psychometric properties followed 
      well-accepted international guidelines. RESULTS: Confirmatory factor analyses 
      yielded the following indices: MHLC-A (tridimensional model): chi2[df]=223.45[132], 
      p-value <0.01; CFI=0.87; TLI=0.85; RMSEA=0.07 (0.07-0.08); WRMR=3.00. GSES-Brazil 
      (unidimensional model): chi2[df]=788.60[35], p-value <0.01; CFI=0.95; TLI=0.94; 
      RMSEA=0.09 (0.08-0.09); WRMR=2.50. Cronbach's alpha coefficients and Intraclass 
      Correlation Coefficients (ICC2,1) ranged from 0.57 (0.54-0.59) and 0.57 
      (0.47-0.65) for MHLC-A internality to 0.80 (0.79-0.81) and 0.71 (0.66-0.77) for 
      GSES-Brazil, respectively. There was no evidence of ceiling and floor effects. 
      Convergent validity analyses provided further support for construct validity of 
      both scales. CONCLUSION: These findings support the use of the newly developed 
      version of GSES-Brazil for the assessment of general self-efficacy of adult 
      Brazilians. Internal consistency was lower than ideal for MHLC-A, indicating 
      these subscales may need further refinements to provide a more psychometrically 
      sound measure of control beliefs.
