Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Nudge is a set of methods aimed at helping people adopt a behavior by a gentle prompt, conscious or not. Classically, Nudges rely on heuristics and cognitive biases. These methods have been studied for years in social psychology and are receiving renewed attention since the awarding of the Nobel Prize in economics to Richard Thaler for his work on the application of Nudge to the economy.

Health professionals are very inadequately vaccinated (25 to 45% of the population). Some studies have shown that a Nudge based on intent implementation can significantly increase vaccination coverage. However, few studies evaluate the acceptability of Nudge or its application to health professionals.

The investigators sought to apply a Nudge based on availability heuristics to health professionals, in order to evaluate its effectiveness and terms of behavior adoption (influenza vaccination) and its acceptability.

The investigator's hypothesis is that Nudging is both effective and acceptable and that people found nudging more acceptable if they have been exposed to a nudge.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators asked residents in general medicine to pass a questionnaire including a Nudge. This Nudge was the influenza vaccine prescription form accompanied on the back of the telephone numbers of the occupational health centers of the hospitals where residents were on probation.

The interns of the group "Nudge" saw at the end of their questionnaire the following statement: "If you are not vaccinated against the flu so far, you can get the form stapled to this questionnaire, it will allow you to get the vaccine in pharmacy. On the back you will also find practical information about immunization services at your place of training. " A group will receive an implemented Nudge questionnaire, a group will receive a questionnaire without Nudge and a control group will not be asked. (Phase 1) The 3 groups will receive a month later a questionnaire evaluating the effectiveness in terms of immunization coverage, and the acceptability of the Nudge, for oneself and for others. (Phase 2) The control group will only receive the Phase 2 questionnaire to control the Hawthorne effect.

The difference between the 3 groups will consist exclusively in the exposure of the participants to:

* A questionnaire on their attitude (opinion) towards vaccination;
* The numbers of the occupational health vaccination centers of their places of training;
* The flu vaccine prescription form, to be signed and stamped by a doctor (also already freely available on the internet)

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

one group receives a form with the nudge, one group receives the same form without nudge and another group doesn't receive any form

Primary Study Purpose

BASIC_SCIENCE

Blinding Strategy

NONE

In the first pat of the study, participants are unaware of the fact we are trying to nudge them. In the second part, they are explained and asked what they feel about nudging
