Brief Summary

The main objective is to test the superiority of a newly developed mobile application - RECAP\_MyLife - for data collection in cohort studies in order to increase participation in follow-up evaluations. We hypothesize that data collection through a mobile app will contribute to improvements in participation. An accurate assessment of the potential benefits and drawbacks of using this mobile technology tool for data collection in cohort studies will be conducted. For such, the study will be conducted in three cohorts developed in different temporal, cultural, and geographic contexts, increasing the generalization of the results found. This evaluation is intended to contribute to the development of more appropriate tools for data collection and consequently to increase participation in epidemiological studies.

Study Arms (2)

Intervention group RECAP_MyLife mobile app

EXPERIMENTAL

Participants in the intervention group will be instructed to use the mobile app daily for four weeks.

Device: RECAP_MyLife mobile app

Control group

ACTIVE COMPARATOR

Comparator will be the usual data collection method applied by the cohorts.

Other: Usual data collection methods

Interventions

RECAP_MyLife mobile app DEVICE

The intervention will be the use of a mobile application for collecting data from cohorts participants, envisioning to engage participants and collect continuous unbiased records. Participants in the intervention group will install the mobile application on their smartphones on the beginning of the trial and will be asked to self-report information on mood every day. Simultaneously, physical activity (number of steps) will be passively tracked through real-time information. Participants will complete baseline and post-intervention measures of mood status based on the "Circumplex Mood Model" and IPAQ-Short form. Following these measures, participants will be asked to complete questionnaires on usability (SUS scale) and acceptability of the intervention.
