The Q4 Model

Psychological Associates is the only talent management company that uses the Dimensional® Model of Behavior™. It was developed by our co-founders Drs. Robert E. Lefton and V.R. Buzzotta to organize objective, observable behavior into four quadrants.

Organizations can challenge their talent to grow and adapt by adopting optimal behavior patterns. We believe Q4 behavior combines a strong desire for accomplishment with a high regard for people to generate long-term business success.

Take the Behavior Questionnaire to learn how to work more effectively with others.
