 The aim of present study was to investigate some psychometric features of quality of life questionnaire (Q L Q). QLQ developed by Evance and Cope in 1989, for assessing adult quality of life. It includes 16 dimensions and totally consisting of 192 questions. The Major assumption of the questionnaire is that the behavior of adults in response to particular aspects of environment could be representative of his/ her quality of life. Thus QLQ has tried to identify a multidimensional measure of an individual's behavior .In this study 400 teachers (200 men, 200 women) were selected through stepwise clustering procedure from different schools of Tehran north south east, and west regions. Obtained results showed appropriate Chronbach Alpha for total as well as for the 1st and 2nd parts of questionnaire. The reliability of the test and correlation between the two halves of the questionnaire was also adequate.

 Test – retest coefficient of correlation for all the 16 sub-scales including QLQ were positive & meaningful. On the other hand, following author's view, each and every item in a sub-scale having more correlation with sub-scales other than its own was omitted, and finally 163 items remained in the questionnaire. Comparing results between men and women as well as Iranian and non-Iranian samples indicating a significant difference for some sub-scales, although the difference between Iranians and non-Iranians for thirteen sub-scales are more obvious. Norm selection for Iranians was done on the basis of original items in the questionnaire and more over, omitted items are presented in related tables.
