Personality was hypothesized to predict college adjustment because of the role of perceived social support. A sample of III freshmen completed measures of personality, perceived social support, and college adjustment twice in their 1st semester. Perceived social support mediated the relationships between 3 personality factors (Emotional Stability, Social Boldness, and Abstractedness) and college adjustment, highlighting perceived social support as a point of intervention to improve 1st-semester students' college adjustment.
