Abstract :Obesity is a disease that affects quality of life. This study was planned to evaluate the Turkish validity and reliability of the LAVAL quality of life questionnaire. The study was conducted in Izmir Bayraklı District Health Directorate Healthy Life Center No. 1 (October 1, 2021-November 15, 2021) and Gaziemir Municipality (November 15, 2021-March 15, 2022). Dokuz Eylul University Ethics Committee accepted the study on 22.12.2021, with the decision number 2021/38-08. People with a body mass index ≥ 30 kg/m2 and who met the inclusion/exclusion criteria were included in the study. In addition to the Laval Questionnaire, the SF-12 general health quality of life questionnaire and the Obese Specific Quality of Life Scale were used. For the adaptation of the Turkish version of the questionnaire, language validity was first ensured by the back translation method. The mean age of the 235 volunteer participants was 49.11 ± 13.1 years. The Kaiser-Meyer-Olkin coefficient for exploratory factor analysis was calculated as 0.92. RMSEA was 0.61 (RMESA<0.80). Cronbach\'s alpha value, which is an indicator of the internal consistency coefficient of the Laval Questionnaire in obese individuals, was calculated as 0.95. Obesity Specific Quality of Life and SF-12 Quality of Life Scale scores were found to have a statistically significant effect on the Laval Questionnaire score (p<0.05). The Laval Questionnaire is a valid and reliable questionnaire to measure the quality of life of individuals with obesity in the Turkish population.
