After several months of work and preparations, the first study within the POSTCOVID-AI project was launched on 15 November, which will allow us to obtain our first results on the impact of the pandemic on the well-being of the Spanish population.
The prerequisites to be able to participate in this study were to be of legal age and to have a mobile phone with an Android operating system. A very important aspect to consider in the selection of participants was that they should faithfully represent the general population. To this end, rigorous stratification criteria were followed based on certain socio-demographic characteristics. The final result was a group of 110 people (50% women) aged between 18 and 70. Another important characteristic taken into account was representativeness in relation to geographical distribution, for which the Nielsen criteria for the division of areas were followed. Finally, a representative distribution of the participants according to their gross annual income, has been sought, considering five ranges from less than 12,450€ to more than 60,000€.
During the month of the study, participants will have to keep the project application installed on their mobile phones and answer the questionnaires received throughout the day
