Modeling dimensions of choice in accepting the smallpox vaccine.

OBJECTIVE

To model the dimensionality of understanding refusal to be vaccinated against smallpox.

METHOD: The Smallpox Vaccination Choice Questionnaire was administered to a convenience sample of students. Through a series of factor analyses, responses were subjected to a statistical evaluation of the underlying factor structure of potential influences on choice.

RESULTS

The analyses suggest 5 dimensions: knowledge, perceptions of risk and worry, psychological distress, general beliefs about vaccines, and age.

CONCLUSION

This model will be used to help identify targets of intervention to increase acceptance of the vaccine and satisfaction with choice.
