Thestructured questionnaire consist of WHOQOL-BREF were used as research instruments. When dividing the participants into three groups according to the level of total QOL score, in physical domain majority (96.2%) had fair level QOL score. In psychological domain veryfew(5.4%) had poor level and more than half (53.2%) had fair level QOL score and rest of them had good QOL score (41.4%). more than one third (37.2%) and nearly half(47.0%) had fair and good level respectively whereas rest of them (15.8%) had poor level of QOL in Social domain. In environmental domain a minimum number(3.8%) had poor QOL score but almost half (43.6%) and more than half (52.6%) had fair and good level of QOL score. The Cronbach’s alpha coefficient of WHOQOL-BREF was adequate (0.914) for all 26 questions and for each domain the values are: Physical health domain (0.812), Psychological health domain (0.831), Social relationship domain (0.68) and Environmental health domain (0.78).
