Application of WHOQOL-BREF in measuring quality of life in health-care staff

Background: the objective of this study was to evaluate the quality of life of neyshabur health-care staff and some factors associated with it with use of whoqol-bref scale. methods: this cross-sectional study was conducted on 522 staff of neyshabur health-care centers from may to july 2011. cronbach's alpha coefficient was applied to examine the internal consistency of whoqol-bref scale; pearson's correlation coefficient was used to determine the level of agreement between different domains of whoqol-bref. paired t-test was used to compare difference between score means of different domains. t-independent test was performed for group analysis and multiple linear regression was used to control confounding effects. results: in this study,a good internal consistency (� = 0.925) for whoqol-bref and its four domains was observed. the highest and the lowest mean scores of whoqol-bref domains was found for physical health domain (mean = 15.26) and environmental health domain (mean = 13.09) respectively. backward multiple linear regression revealed that existence chronic disease in staff was significantly associated with four domains of whoqol-bref,education years was associated with two domains (psychological and environmental) and sex was associated with psychological domain (p < 0.05). conclusions: the findings from this study confirm that the whoqol-bref questionnaire is a reliable instrument to measure quality of life in health-care staff. from the data,it appears that neyshabur health-care staff has whoqol-bref scores that might be considered to indicate a relatively moderate quality of life.
