In France, vaccination coverage of adolescents remains suboptimal, partly because of a loss of confidence, favoring the re-emergence of epidemics. Despite the extension of mandatory vaccination, some vaccines are still recommended.

Motivational Interviewing (MI), which reinforces a person's own motivation and commitment to change, has been shown to be effective in addiction, nutrition, physical activity and vaccination (Promovac study in Quebec). However, it has not been evaluated in the French cultural context (with mandatory vaccination).

The main objective will be to measure the effect of training in MI for general medical interns at the end of their studies on the vaccine hesitancy (VH) of parents of adolescents consulting in primary care, using a validated scale: VCS.

A multicenter study will be conducted in two university departments of general medicine (Marseille and Nice), comparative, clustered exposure/non-exposure type. It will compare the HV of parents of adolescents during consultations by 2 different groups of interns:

  • a group of interns trained in MI,
  • a group of interns not trained in MI. The randomization will be done by random draw from the 3rd year list of GP interns not in SASPAS training.

After the MI training, each intern in the "exposed" and "unexposed" groups will have 4 months to include at least 3 parents of adolescents seen in consultation.

Descriptive analyses will be performed followed by statistical analysis by modeling the standardized HV score using hierarchical linear regression.

Training of interns in MI applied to vaccination will increase their knowledge, skills and confidence in using this technique.

We can expect a decrease in VH among parents in primary care who consulted a physician trained in MI.
