Abstract : Introduction Mental
disorders represent the second cause of years lived with disability
worldwide. Suicide mortality has been targeted as a key public health
concern by the WHO. Smartphone technology provides a huge potential to
develop massive and fast surveys. Given the vast cultural diversity of
Mexico and its abrupt orography, smartphone-based resources are
invaluable in order to adequately manage resources, services and
preventive measures in the population. The objective of this study is to
conduct a universal suicide risk screening in a rural area of Mexico,
measuring also other mental health outcomes such as depression, anxiety
and alcohol and substance use disorders. Methods and analysis A
population-based cross-sectional study with a temporary sampling space
of 9 months will be performed between September 2019 and June 2020. We
expect to recruit a large percentage of the target population (at least
70%) in a short-term survey of Milpa Alta Delegation, which accounts for
137 927 inhabitants in a territorial extension of 288 km 2 . They will
be recruited via an institutional call and a massive public campaign to
fill in an online questionnaire through mobile-assisted or
computer-assisted web app. This questionnaire will include data on
general health, validated questionnaires including Well-being Index 5,
Patient Health Questionnaire-9, Generalized Anxiety Disorder Scale 2,
Alcohol Use Disorders Identification Test, selected questions of the
Drug Abuse Screening Test and Columbia-Suicide Severity Rating Scales
and Diagnostic and statistical manual of mental disorders (DSM-5)
questions about self-harm. We will take into account information
regarding time to mobile app response and geo-spatial location, and
aggregated data on social, demographical and environmental variables.
Traditional regression modelling, multilevel mixed methods and
data-driven machine learning approaches will be used to test hypotheses
regarding suicide risk factors at the individual and the population
level. Ethics and dissemination Ethical approval (002/2019) was granted
by the Ethics Review Board of the Hospital Psiquiátrico Yucatán, Yucatán
(Mexico). This protocol has been registered in ClinicalTrials.gov. The
starting date of the study is 3 September 2019. Results will serve for
the planning and healthcare of groups with greater mental health needs
and will be disseminated via publications in peer-reviewed journal and
presented at relevant mental health conferences. Trial registration
number NCT04067063 .
