This is a case study illustrating de Bono’s Six Thinking Hats model when used in a supervision session with a group of counselor interns who were nearing the end of their graduate counseling program. They were enrolled in their last internship course. While one intern discussed the case,the supervisor instructed other interns “wearing” the six thinking hats to aid her in conceptualizing the marital counseling case she was presenting. The volunteer herself also wore each hat during the process. In the case study below, the female counselor intern will be described as the volunteer.
