The primary purpose of this study was to test career construction theory's model of adaptation among Turkish undergraduate students in their final year. Additionally, the Career Commitment Scale was adapted for Turkish university students to ensure its appropriateness as a measure in testing the model of adaptation. Data obtained from the first sample (172 undergraduate students) were used to adapt the Career Commitment Scale and data obtained from a second group (243 undergraduate students in their final year) was used to test the career construction theory model of adaptation. The results of the study support the career construction theory's model of adaptation. Additionally, the eight-item model for the adapted Career Commitment Scale demonstrates good fit and acceptable internal consistency.
