In this study university students interpersonal problem solving approaches were investigated in terms of solution focused approach and humor styles. The participants were 773 (542 female and 231 male, between 17-33 years old) university students. To determine the university students' problem solving approaches "Interpersonal Problem Solving Inventory," to determine solution focused approaches "Solution Focused Inventory," and to determine humor styles "Humor Styles Questionnaire" were used.In data analysis, Pearson Product-Moment Correlation Coefficient technique was used to reveal the relation between solution focused approach and interpersonal problem solving approaches and also between humor styles and interpersonal problem solving approaches. Multiple Linear Regression Analysis technique was used to determine predictive power of the solution focused approach and humor styles on interpersonal problem solving approaches. According to the results of correlation analysis, significant relations were revealed between solution focused approach and problem solving approaches and also between humor styles and problem solving approaches. According to the regression analysis, solution focused approach and humor styles significantly predict all the problem solving approaches (problems in a negative way, constructive problem solving, lack of self-confidence, unwillingness to take responsibility, insistent-persevering approach). Discussion and suggestions were included within the results obtained.
