Impostor scale assessment

Pauline Clance, who described Impostor Phenomenon in 1978 alongside Suzanne Imes, has published a scale to help us self-assess our Impostor Phenomenon feelings.
What they say
The Impostor Test was developed to help individuals determine whether or not they have IP characteristics and, if so, to what extent they are suffering.
After taking the Impostor Test, add together the numbers of the responses to each statement. If the total score is:
<40: The respondent has few Impostor characteristics
41-60: The respondent has moderate IP experiences
61-80: The respondent frequently has Impostor feelings
>80: The respondent often has intense IP experiences.
The higher the score, the more frequently and seriously the Impostor Phenomenon interferes in a person’s life.
