ABSTRACT
PURPOSE: Burn patients may encounter social barriers and stigmatization. The objectives of this study were to adapt the Social Comfort Questionnaire (SCQ) into Brazilian Portuguese and to assess the psychometric properties of the adapted version. METHODS: Cross-cultural adaptation of the 8 items of the SCQ followed international guidelines. We interviewed 240 burn patients and verified the SCQ internal consistency, test-retest reliability and construct validity, correlating the scores with depression [Beck Depression Inventory (BDI)], affect/body image and interpersonal relationships [Burns Specific Health Scale-Revised (BSHS-R)] and self-esteem [Rosenberg's Self-Esteem Scale (RSES)]. We also performed a confirmatory factor analysis (CFA). RESULTS: The cross-cultural adaptation resulted in minor semantic modifications to the original SCQ version. After CFA, a reduced 6-item version showed satisfactory fit to the one-factor model (RMSEA = 0.05, CFI = 0.99, TLI = 0.99). Cronbach alpha's was 0.80, and test-retest intraclass correlation coefficient was 0.86. The final version presented a strong negative correlation with depression (BDI), and strong positive correlations with affect/body image (BSHS-R), interpersonal relationships (BSHS-R) and self-esteem (RSES) (all p < 0.001). CONCLUSION: The results showed that the SCQ Brazilian Portuguese adapted version complies with the validity and reliability criteria required for an instrument assessing social comfort in Brazilian burn patients. The Brazilian version yields a single score that is easy to interpret and well understood by patients.
