Development of the Fogg Intent-to-Screen for HIV (ITS HIV) questionnaire.

In this paper, we describe the development and psychometric properties of the Fogg Intent-to-Screen for HIV questionnaire (ITS HIV), which measures peoples' beliefs and intentions toward HIV screening. The ITS HIV was developed using the Theory of Planned Behavior as the framework for a developmental process that included qualitative interviews, a validation phase, two pilot tests, and a field test of the final 55-item questionnaire. The field test involved 312 homeless persons from five New England states.

HIV screening: beliefs and intentions of the homeless.

HIV screening is the first step in identifying HIV infection; however, the HIV screening rates remain low. Homeless people in the United States are at risk for HIV infection, yet their acceptance of HIV screening remains poorly understood. The purpose of this study was to investigate beliefs and intentions of the homeless toward HIV screening.
