Primary use / Purpose: 

The HIV Knowledge Questionnaire (18-item version) is a brief self-administered measure of the individual’s HIV-related knowledge. This instrument contains 18 forced-choice statements (‘true’,’false’, ‘don’t know’) related to, in particular, knowledge related to sexual transmission. A single summary score is yielded overall, with higher scores significant of greater HIV-related knowledge.


The HIV Knowledge Questionnaire (HIV-KQ-18) was designed to provide a more concise and well-established measure of HIV-related knowledge in street outreach, fieldwork, and intervention settings. The scale aims to tap into other related constructs, for which the original HIV-KQ 45-item scale did not address.


Psychometric evaluation of the HIV-KQ-18 is reported in Carey and Schroder (2002).
