Similarly, semester-wise comparison of depression scores indicated that semester II students suffered from more depression than semester III students. It might be because of a number of reasons like academic demands for semester II students are more as students are still new to the university and less familiar with its environment. These findings are consistent with another study, which found junior students more vulnerable to depression compared to their senior students (Wong et al., 2006). Some studies have compared rates of depression between undergraduate and postgraduate students. One study did not find any difference in depression scores of students on year level basis (Vredenburg et al., 1988), whereas another study (Oliver and Burkham, 1979) reported depression to be negatively related to the years in school; students were more depressed in early years than later years.
