Abstract

Respondents understood the questionnaire as assessing the safety of their blood. This interpretation served as the backdrop for the question-response process for each individual question. Specifically, rationale for answers was framed as much or more by the questionnaire's general purpose as by the specific topic of individual questions. This pattern of interpretation was the key factor responsible for both false-positive and false-negative response errors and did not vary by demographic, including in MSM.
