Background/Aim:
This study aims to evaluate the reliability and validity of the Amblyopia and Strabismus Questionnaire (AandSQ) that is translated into Turkish.
Materials And Methods:
This is a methodological study. A total of 149 patients took part in the survey research between December 2012 and June 2014 in an university hospital, and 37 were retested. Cronbach's alpha coefficient was used for the questionnaire's reliability analysis.
Results:
Cronbach's alpha coefficients for the subscales of fear of losing the better eye, distance estimation, visual disorientation, double vision, and social contact and appearance were found to be 0.80, 0.88, 0.95, 0.80, and 0.81, respectively. Five factors determined by the exploratory factor analysis explained 69.87% of the total variance.
Conclusion:
The Turkish version of the AandSQ is found as a reliable and valid scale for analyzing Turkish society. The AandSQ might be helpful for measuring quality of life in patients with strabismus.
