Abstract

The purposes of this research were 1) to study depression of first-year undergraduate students at a university in Songkhla province; 2) to study the relationship among psychological factors, obligation factors, relationship factors, and depression among these students; and 3) to study factors affecting their depression. Data was collected by surveying 180 students. The research instrument was a questionnaire consisting of 1) general information about the respondents 2) the Patient Health Questionnaire for Adolescents (PHQ-A) to measure levels of depression, and 3) a questionnaire on psychological factors, obligation factors, and relationship factors. The study identified Cronbach's alpha coefficients, which are equal to 0.76 - 0.93. The data was analyzed for the average, standard deviation, Pearson correlation coefficient, and multiple regression coefficient. The results of the research were as follows:1) The first-year undergraduate students had an overall mean depression score of 9.29 (SD.=4.55). It was found that 119 of them had a mild level of depression accounting for 66.11 percent, 41 had a moderate level of depression accounting for 22.78 percent, 13 had a high level of depression accounting for 7.22 percent, and 7 people had a severe level of depression accounting for 3.89 percent. 2) Self-esteem (r = -.63, p < .05), life satisfaction (r = -.49, p < .01), rumination (r = -.66, p < .01), relationships with friends (r = -.38, p < .01), and relationships with family (r = -.35, p < .01) were negatively related to depression with statistical significance. Problem solving (r = .34, p < .01), study stress (r = .51, p < .01), and financial responsibility (r = .38, p < .01) were positively related to depression with statistical significance. 3) Three factors significantly affect student depression: rumination, self-esteem, and relationship with family. These factors can predict 54.70% of the depression of first-year undergraduate students at a university in Songkhla Province.????????????????????????????????????????? 1) ????????????????????????????????? 2) ???????????????????????????????????????? ????????????????? ??????????????????????????????????????????????? ??? 3) ????????????????????????????????????????????????????????????????????????? 1 ?????????????????????????????????? ????????????????????????????????????? 180 ?? ??????????????????????????????????????? ?????????? 1) ?????????????????????????????? 2) ???????????????????????????????
