Abstract

This study explored the relationship between psychotherapists' personality and choice of theoretical orientation. A total of 493 participants completed a web-based survey. Personality was assessed using the HEXACO Personality Inventory while theoretical orientation preference was assessed using a modified version of the Theoretical Orientation Profile Scale-Revised. In the practitioner sample, the Humanistic/Existential scale was found to be significantly correlated with the Openness Unconventionality scale. Results further revealed that practitioners' theoretical orientation preference differed based on the Conscientiousness and Openness personality dimensions. In the student sample, the cognitive-behavioural orientation was significantly correlated with Conscientiousness and the Conscientiousness Prudence facet scale. The humanistic/existential scale was significantly related to Openness and the Openness Creativity subscale. Results further indicated that students' theoretical orientation preferences were different based on the Agreeableness, Conscientiousness, and Openness personality dimensions. Lastly, results showed that students' theoretical orientation preferences were significantly related to their supervisors'. Implications for future research, training, and practice are discussed.
