This questionnaire enables you to obtain essential information about your participants (gender, age, socio-professional category).
The various criteria assessed by this questionnaire are traditional population segmentation criteria.
If you are targeting a specific population, these indicators will tell you whether your participants correspond to your target sample.
This information will also enable you to check that your sample is representative of the overall population.

This questionnaire also enables you to measure mitigation variable (trust propensity, willingness to accept the use of AI technologies, motivation, effort expectancy, AI literacy, reputation of the company). 
These variables allow to control potential biases and confounding factors, i.e. variables that may unintentionally cause systematic errors or distortions and could lead to inaccurate results or non-representative results. Ignoring them could lead to biased outcomes and diminish the impact of the AIA index.

If you want to study different groups of participants, the socio-demographic data will enable you to create your different conditions.
