Question re. the COGIATI test.

Hello!

Tried to find this question in the forums but failed. I am thinking of making use of the COGIATI test in my newest story, which takes place in the 1980s. The character begins to question himself at the home of a friend whose father is a therapist. As an easy first step, the father digs a copy of the test out of his... desk or book from his shelves or whatever. But I would like to know if the COGIATI test existed that early. I don't mind "bending the rules" to make a story work, but this would be a bit of a strain on credibility. Thank you!
