The purpose of this study is to determine whether young adults' personality traits (conscientiousnes, agreeableness, openness to experience, extraversion, neuroticism) and career decision-making status together predict their career adaptability total score and its sub-dimensions; concern, control, curiosity, confidence. A total of 603 university students, 341 (56.6%) female and 261 (43.3%) male, participated in the study. The data of the study were collected by using the Career Adaptability Scale, the Adjective Based Personality Test, and the Personal Information Form. Multiple Linear Regression Analysis and Pearson Correlation analysis were used to analyze the data. The findings of the study showed that young adults' career decision making status and personality traits together predicted career adaptability total score (31%) and its sub-dimensions (Concern; 19%, Control; 29%, Curiosity; 19%, Confidence; 26%). The findings of the study have been discussed based on the relevant literature. The limitations of the study are stated. The implications of the study results for theory, future research and practice are presented.
