Brief Summary

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.

Conditions

Vaccination Hesitancy

Outcome Measures

Primary Outcomes (1)

• Vaccine hesitancy score of parents of adolescents

  Score measured using the validated VCS: Vaccination Confidence Scale. This scale is composed of 8 items, each receiving a score ranging from 0 (strongly disagree) to 10 (strongly agree), with the highest score expressing the highest degree of confidence in vaccines and the lowest expressing the highest degree of VH.

  through study completion, an average of 2 years

Secondary Outcomes (3)

• Behaviour, beliefs and knowledge about vaccines

  through study completion, an average of 2 years

• Parent and medical intern satisfaction with the consultation

  through study completion, an average of 2 years

• MI learning, knowledge and skills for vaccination promotion in interns
