Figure 1. Conceptual model for parental decision-making for HPV vaccine in Piura.

The figure illustrates how a variety of different perceptions, experiences, knowledge, and attitudes provide a background context and influence a mother and/or father’s decision to vaccinate their daughter. Divided into phases, the decision-making model demonstrates that if the basis of this decision is sufficiently positive, parents may proceed to accept vaccination; however, if doubts remain, parents may seek further information or opinions and may modify their decision, crystallizing it into refusal or acceptance. Model tested in northern Peru.
