Background:Primary care physicians (PCPs) play a key role regarding vaccination in France. The aims of the present
study were to define the scoring rules and to assess the measurement properties of the‘Determinants of Intentions to
Vaccinate’ (DIVA
©
) questionnaire that aims to assess PCPs’ attitudes and beliefs toward vaccination.
Methods:The DIVA questionnaire was derived from a literature review and PCPs focus groups. Scoring and early
validation of the DIVA questionnaire were determined during a cross-sectional study conducted in France. During
the study, PCPs had to complete the DIVA questionnaire for any of the six vaccine-preventable diseases (VPDs) to which
they were randomly assigned (measles, pertussis, pneumococcus infection, seasonal influenza, human papillomavirus
-HPV- infection and tetanus). Descriptive analyses of itemsand the analysis of the grouping of items into domains were
conducted. Internal consistency reliability and construct validity was assessed according to each VPD.
Results:The DIVA questionnaire was completed by 1,069 PCPs and was well accepted. The‘Commitment of the PCP to
the vaccination approach’ score showed very good internal consistency reliability (Cronbach’s alpha >0.70 overall and for
each VPD). The construct validity of the DIVA questionnaire was confirmed.
Conclusions:The DIVA questionnaire is a valid and reliable measure of PCPs’ attitudes and beliefs toward vaccination.
