The main objective of this study is to determine the stress forming factors of college students and to determine the relationship between their social problem-solving abilities and interpersonal style. The further object of research is to contribute to a better understanding of relationship between stress factors of students and their various demographic variables such as gender and type of education. The results of analysis revealed that in many stress-forming-factor subscales, women's score were significantly higher than men's. Also, it was determined that, in the "academic issues" subsection, students from first-education scored significantly higher than those from second education. Students' stress scores were predicted by some demographic variables, and problem-solving approaches, and some interpersonal styles. It is considered that the findings can be used for some educational training and counseling services given by the health centers and/or psychological counseling for youths. Specially, "problem-solving skills" and "communication skills" training programs which are offered in these centers will be very important in terms of preventive mental health for students.
