This study aimed to determine whether the adjustment levels of university students differ according to their perceived communication skill levels. The research was carried out with 277 Turkish university students. Data were collected through The Communication Skills Assessment Scale (Korkut, 1996) and the Hacettepe Personality Inventory (Ozguven, 1992). The findings of the study revealed that personal, social, and general adjustment levels were significantly related to perceived communication skill levels. Students who have high perceived communication skill levels had significantly higher personal, social, and general adjustment levels. Results are discussed in relation to their implications for effective communication skills of university students.
