Abstract

This research developed and evaluated a brief but comprehensive measure of knowledge about sexually transmitted diseases (STDs) for use in research and applied settings. Questionnaire construction involved a review of empirical precedents as well as qualitative work with STD experts (n = 6) and the target population (n = 40). Eighty-five items were piloted (n = 50) and tested (n = 391) with college students. Item- and test-level analyses identified items that were eliminated to shorten the questionnaire. Factor analyses revealed a two-factor model of STD knowledge, including a Cause/Cure factor and a General Knowledge factor. Six supplemental items were added to the final questionnaire for their public health value and resulted in the 27-item STD-Knowledge Questionnaire (STD-KQ). The STD-KQ demonstrated internal consistency (α = .86) and test–retest reliability (r = .88) over a brief period. Evidence for the validity of the STD-KQ was obtained through a comparison with a validated HIV knowledge questionnaire (Carey & Schroder, 2002); treatment outcome sensitivity was obtained in response to an educational program. Use of the STD-KQ will enable researchers and health educators to identify knowledge deficits, measure knowledge for theory testing, evaluate risk reduction programs, and assess treatment response in research and applied settings.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
