The examination of validity and reliability for Obese Individuals Specific Quality of Life Scale

Objective: The aim of this study was to examine validity and reliability Turkish form Obese Individuals Specific Quality of Life Scale. Methods: This is a methodological study. Form Quality of Life Scale Specific for Obese Persons is a test Likert type scale composed of 15 items an done factors. The scale was applied to persons (n=170) who were consulted to Ege University Faculty of Medicine, Research and Application Hospital Clinical Obesity and suitable research criteria Turkish language validity work of scale has been made by MAPI Institute. That's why the language validity has not been work worked again. Validity of the scale was evaluated with factor analysis and construct validity and reliability was evaluated with item-total score correlation, internal consistency and continuity methods. Results: The Cronbach alpha was 0.90. Item total correlation coefficients of scale ranged from 0.33-0.71 and none of the items of scale was deleted. Results of test score were obtained. In order to estimate scale stability between different occasions test-retest reliability was performed and it has seen that there was a strong and linear correlations between measures. At the result of the factor analysis of the scale one factors which can account for %62.57 of the total variance of test score was obtained. Conclusion: Obese Individuals Specific Quality of Life Scale was decided to be a valid and reliable scale.
