Summary
Background & aims

The purpose of this study was to validate the Greek version of Suter questionnaire in order to be used for the evaluation of patients after Laparoscopic Sleeve Gastrectomy (LSG).

Methods

A total of 170 patients were enrolled in the study.

Results

The correlation coefficients for criterion validity had range between 0.202 (Food Tolerance) and 0.252 (Suter Total Score) (p < 0.05).There was moderate correlation between the questionnaire's subscales and the Hematocrit which satisfied the criterion validity marginally. The internal consistency measured with Cronbach's alpha yielded a value of 0.866 for the factor tolerance and 0.78 for the factor symptoms, which indicate excellent internal consistency. Excellent test-retest reliability with ICC of 0.997 for food tolerance and 0.990 for symptoms were also observed. The Suter questionnaire demonstrated a high sensitivity to detect clinical changes.

Conclusion

The Greek version of Suter questionnaire seemed to be valid and reliable to assess morbidly obese patients after LSG.
