What predicts performance in Canadian dental schools?

Area of Science:

• Dental Education
• Psychometrics
• Admissions Selection

Background:

• Dental schools face challenges in selecting top candidates from competitive applicant pools.
• Cognitive and non-cognitive factors are used in dental school admissions, with growing interest in personality assessments.
• The predictive validity of existing selection tools needs continuous evaluation.

Purpose of the Study:

• To examine the validity of cognitive and non-cognitive factors in Canadian dental school admissions.
• To assess if personality measures improve prediction of dental student performance beyond interviews and the Dental Aptitude Test.

Main Methods:

• Evaluated the predictive validity of interviews, the Dental Aptitude Test (DAT), and a personality measure for dental student performance.
• Assessed the contribution of personality facets (Openness to Experience, Extroversion) to predicting preclinical and clinical success.

Main Results:

• The Dental Aptitude Test effectively predicts preclinical academic success, with reduced validity for clinical performance.
• Interviews show potential for identifying key behavioral characteristics for dental training.
• Openness to Experience negatively correlated with clinical education aspects; however, specific facets (Ideas, Positive Emotions) improved performance prediction when combined with DAT and interview.

Conclusions:

• The Dental Aptitude Test and interviews are valuable but may not fully capture predictors of clinical success.
• Certain personality facets can enhance the prediction of performance in clinical dental studies.
• Recommendations are provided for optimizing the admissions process for Canadian dental programs.
