Massive Mental Health Screening Using Smartphones in 24 Pre-graduate Education Centers in Mexico City: TEDUCA Survey Protocol

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to make a massive suicide risk and social behavior assessment in 24 pre-graduate education centers in Mexico City (approximately 30,000 students aged between 15 and 22 years), taking also 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. Our main hypothesis is that identification of suicide risk in the Mexico City's student community is feasible using their own smartphones and can serve as both a population screening tool for early specialist referral, as well as a tool for evaluating social behavior strategies and their relation to suicide behavior.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Suicidal ideation | Columbia-Suicide Severity Rating Scale (C-SSRS) is encompassed into MeMind for this purpose. In C-SSRS, four constructs are measured. The first is the severity of ideation, which is rated on a 5-point ordinal scale from 1=wish to be dead to 5=suicidal intent with plan. The second is the intensity of ideation, which comprises 5 items, each rated on a 5-point ordinal scale: frequency, duration, controllability, deterrents, and reason for ideation. The third is the behavior, which is rated on a nominal scale that includes actual, aborted, and interrupted attempts; preparatory behavior; and nonsuicidal self-injurious behavior. And the fourth is the lethality, which assesses actual attempts; actual lethality is rated on a 6-point ordinal scale. Results are coded in the instrument itself with colored labels that indicates definitions of suicidal ideation and behavior, quantify both of them and gauge their severity. Definitions are available elsewhere (http://cssrs.columbia.edu). | 1 Day | 
| Social Behavior | The assessment of social interaction will be carried out through six games that expose the participant to decision-making in preset environments with very simple and easily understandable rules (Dictator's Game, Prisoner's Dilemma, Loss Aversion, Risk Aversion, Trust Game or The Investment Game, and Ambiguity Aversion). | 1 Day |
