Population Screening Using Smartphone in Milpa Alta

• Conditions: Depression; Anxiety; Alcohol Abuse; Depressive Disorder; Suicidal Ideation; Drug Abuse
• Interventions: Other: Self-administered evaluation questionnaire

• Registration Number: NCT04067063
• Lead Sponsor: Instituto de Investigación Sanitaria de la Fundación Jiménez Díaz

Brief Summary

The objective of this study is to make a suicide screening in the entire population of Milpa Alta (approximately 150,000 inhabitants), taking into account other outcomes such as depression, anxiety, alcohol and drugs. For this, an app for Smartphone (MeMind) or a web platform (www.MeMind.net) will be used in which the participants will take a self-administered questionnaire, composed of several psychometric instruments .

It is expected that 70% of the population between 15 and 70 years old can do so directly with their own Smartphone, although web access posts will be enabled in educational and municipal units to avoid discrimination based on age or access to technology.

Our main hypothesis argues that the early identification of people at risk in almost the entire community can be done with an App for Smartphone, serving to depict a map of mental health and related needs of the population, serving for the planning of healthcare services of the local environment, and ultimately for the best assistance of groups and individuals with greater needs through their identification and early reference to medical assistance.
