Hominoid Personality Questionnaire

The Hominoid Personality Questionnaire (also: HPQ) is a personality rating instrument used for non-human primates. It is an extended version of the Orangutan Personality Questionnaire, which was an extended version of King and Figueredo's^[1] Chimpanzee Personality Questionnaire. The HPQ has been used to assess personality in non-human primate species (e.g. chimpanzees, orangutans, rhesus macaques).

The HPQ contains 54 adjectives followed by a description. Forty-one items were taken from the 75 items of Goldberg's^[2] "Big Five". Examples include Dominant, Sympathetic, Helpful, Sensitive, Submissive, Dependent, Independent, Fearful, Decisive, Timid, Cautious, Intelligent, Persistent.
