Adaption and validation of the adherence barriers questionnaire for HIV patients on antiretroviral therapy (ABQ-HIV)

The aim of this investigation was to develop and validate a respective questionnaire (Adherence Barriers Questionnaire for HIV: ABQ-HIV), based on an earlier version of the ABQ.

The study showed that the ABQ-HIV is a practical, reliable, and valid instrument for identifying patient-specific barriers to

adherence in the HIV treatment that is also useful in identifying HIV patient subgroups.
