This study aims at determining the mediating effect of academic intrinsic motivation on the relationship between both students' academic selfefficacy and dispositional hope levels to their academic procrastination habits. The data were collected from a sample of 252 college students, 69 males (27.4%) and 183 females (72.6%), aged between 18 and 33 (X = 20.55; Sd =1.52) studying at a state university located in the Central Black Sea region of Turkey using a correlational survey model. Academic Self Efficacy Scale, Dispositional Hope Scale, Academic Intrinsic Motivation Scale, and Aitken Academic Procrastination Scale were used as data collection tools. Descriptive statistics of the sociodemographic characteristics were presented, and Pearson correlation analysis was conducted to determine the correlations between variables by using SPSS statistical package programme. The hypothesis measurement model and the mediating effect were examined by Structural Equation Modeling (SEM) by using LISREL statistical software. The obtained results showed that significant (low and moderate) relationships exist between variables and the model tested in the study yielded acceptable and good fit index values. A complete mediating effect of academic intrinsic motivation on the relationship between both academic self-efficacy and dispositional hope with academic procrastination was determined. The findings were discussed, and some recommendations were made.
