The present study was an experimental research which was applied for increasing of the life tendencies and decreasing the loneliness of the university students, and in which the effect of psychological counselling in group on loneliness level was analysed. The present study consisting of mix measurements was carried out by 2x2 split-plot in order to indicate that the factor A (Group: test-placebo-control) different test conditions and factor B (Measurements: pre-test/post-test) repetitive measurements depend on time. The independent variable of the research was "the psychological counselling in group programme" which was only applied between pre-test and post-test. The dependent variable of the research was the life orientation and loneliness levels of the students. There were 17 students in test group and 17 students in control group. Life Orientation Test and UCLA Loneliness Scale were used as a data collection tool. It was tested with two-factors variance analysis that whether there was a significant difference between pre-test and post-test points of "life orientation test" and "loneliness scale" of the group to which psychological counselling in group programme was applied (test group) and the group to which placebo activity was applied (placebo-control group). Findings of the research indicate that there was a significant difference between post-test life orientation and loneliness points of test and placebo-control groups according to the pre-test life orientation and loneliness points, and the differences on increasing of optimism points and decreasing of loneliness points of test group students were based on psychological counselling in group programme.
