Background and Objectives: Studies on the effects of studying on a medical student’s quality of life are sparse. The World Health Organization Quality of Life (WHOQOL-BREF) questionnaire is a widely used scale that enables the assessment and international comparisons of the quality of life. The aim of this study was to evaluate psychometric properties of the WHOQOL-BREF questionnaire among Serbian medical students. Material and Methods: We conducted a cross-sectional study that involved 760 medical students at a state medical faculty at the University of Kragujevac, Serbia. The reliability of the WHOQOL-BREF was evaluated using Cronbach’s alpha coefficient and test–retest analysis, and the validity was examined using principal component analysis, with Promax rotation method. Results: Cronbach’s alpha coefficient for the whole WHOQOL-BREF scale was 0.896. Internal reliability for all domains was above 0.70, except for the domain “Social Relationships” (0.533). The test–retest reliability for all domains was significant at p < 0.01 level, showing good stability of the scale. Principal component analysis with Promax rotation method indicated four main components that explained 49.5% of variance. Conclusion: The Serbian version of the WHOQOL-BREF scale showed satisfactory psychometric properties that facilitate estimation of the quality of life of medical students.

OBJECTIVE: To study the World Health Organization Quality of Life Instrument Bref psychometric properties in a sample of smokers. It is a self-administered instrument to evaluate quality of life. It contains 26 questions allocated to 4 domains: Social, Psychological, Physical and Environmental, there are 2 questions related to the Global domain. METHOD: The sample was formed by 276 tobacco users selected at random. The instruments applied were: World Health Organization Quality of Life Instrument Bref, Fagerström Test for Nicotine Dependence, and Medical Outcomes Study Short-Form 36-item. The statistical analysis was accomplished up by ANOVA, Cronbach's alpha, Pearson's Coefficient and Multiple Regression. RESULTS: The World Health Organization Quality of Life Instrument Bref presented good reliability (Cronbach's alpha 0.9207), converging validation (0.382 < r < 0.753; p < 0.001), discriminant validation and criterion validation (0.554 < r < 0.778; p < 0.001). CONCLUSION: The World Health Organization Quality of Life Instrument Bref proved to be an adequate instrument, with a good level of reliability, being easily and quickly administered.

This study aimed to identify psychometric properties of the World Health Organization Quality of Life 100 questionnaire. Material and methods. A random sample of 1403 Kaunas city men and women aged 35–64 years was examined in 2001–2002. Quality of life was assessed by the self-administered World Health Organization Quality of Life 100 questionnaire. Statistics. Scores of all domains and facets of the questionnaire were transformed to reflect a scale from 0 to 100. The validity and reliability of the questionnaire were evaluated by Pearson’s correlation coefficients and by Cronbach’s α. The relationship between the WHOQOL-100 domains and the two general items (G1 and G4) was assessed using linear regression analysis. Exploratory factor analysis was conducted to explore the factor structure of the data. Results. The mean scores of the World Health Organization Quality of Life 100 questionnaire domains ranged from 51.3±15.1 (overall quality of life) to 72.0±16.4 (level of independence domain). The instrument displayed acceptable Cronbach’s α (0.77–0.91) and test-retest reliability (0.64–0.89). The overall assessment of quality of life (G1) was most strongly associated with the environment (β=0.31), psychological (β=0.18), and social relationships (β=0.17) domains. Overall health (G4) showed the strongest association with the level of independence (β=0.34) and physical (β=0.18) domains. The principal component analysis revealed five-factor solution, which accounted for 57.7% of a total variance. Conclusion. In the Lithuanian population, the World Health Organization Quality of Life 100 questionnaire was found to be a suitable instrument for evaluating quality of life.
