Antecedentes: A medida que las comunidades se preparan para oleadas futuras de la pandemia del COVID-19 se necesitan pruebas sobre su impacto en la salud mental de sub-poblaciones específicas, como es el caso de los estudiantes universitarios. Objetivos: Estudiar la asociación de la proximidad del COVID-19 con síntomas de ansiedad y depresión en estudiantes universitarios. Métodos: Este estudio de tendencias analizó encuestas transversales semanales de muestras probabilísticas de estudiantes de la Universidad de Columbia Británica durante 13 semanas durante la primera ola del COVID-19. La principal variable evaluada fue la proximidad del COVID-19, definida como “conocer a alguien con un test positivo para COVID-19”, que se especificó en diferentes niveles: “conocer a alguien en cualquier lugar del mundo, en Canadá, en Vancouver, en su curso universitario, o en su domicilio”. La proximidad del COVID-19 se incluyó en regresiones lineales multivariables para evaluar su asociación con los resultados primarios, incluidos los síntomas de ansiedad y/o depresión durante los últimos 30 días. Resultados: De 1388 encuestados (tasa de respuesta ajustada =50%), el 5,6% conocía a alguien con COVID-19 en Vancouver, el 0,8% en su curso universitario y el 0,3% en su domicilio. El 10% de los encuestados se sintió abrumado y no pudo acceder a asistencia. “Conocer a alguien en Vancouver”, se asoció con un aumento de 11 puntos porcentuales en la probabilidad de presentar síntomas de ansiedad durante los últimos 30 días (EE =0,05; p≤0,05), moderado por género, con una interacción significativa de la exposición, y ser mujer (coeficiente = - 20 (EE =0,09), p≤0,05). No se encontró asociación con síntomas depresivos. Conclusión: La proximidad de los casos de COVID-19 puede aumentar la probabilidad de síntomas de ansiedad en los estudiantes, particularmente entre los hombres. La mayoría de los estudiantes informa que se las arregla bien, pero se necesitan apoyos adicionales para una minoría emocionalmente abrumada que informa que no puede acceder a asistencia.

Background The World Health Organization World Mental Health International College Student (WMH-ICS) initiative aims to screen for mental health and substance use problems among postsecondary students on a global scale as well as to develop and evaluate evidence-based preventive and ameliorative interventions for this population. This protocol paper presents the Canadian version of the WMH-ICS survey, detailing the adapted survey instrument, the unique weekly cross-sectional administration, the multitiered recruitment strategy, and the associated risk mitigation protocols. Objective This paper aims to provide a methodological resource for researchers conducting cross-national comparisons of WMH-ICS data, as well as to serve as a useful guide for those interested in replicating the outlined cross-sectional methodology to better understand how mental health and substance use vary over time among university students. Methods The online survey is based on the WMH-ICS survey instrument, modified to the Canadian context by the addition of questions pertaining to Canadian-based guidelines and the translation of the survey to Canadian French. The survey is administered through the Qualtrics survey platform and is sent to an independent stratified random sample of 350 students per site weekly, followed by two reminder emails. Upon survey closure every week, a random subsample of 70 nonresponders are followed up with via phone or through a personal email in an effort to decrease nonresponder bias. The survey is accompanied by an extensive risk mitigation protocol that stratifies respondents by the level of need and provides tailored service recommendations, including a facilitated expedited appointment to student counseling services for those at increased risk of suicide. The anticipated sample size is approximately 5500 students per site per year. Results In February 2020, the Canadian survey was deployed at the University of British Columbia. This was followed by deployment at Simon Fraser University (November 2020), McMaster University (January 2021), and the University of Toronto (January 2022). Data collection at all 4 sites is ongoing. As of May 6, 2022, 29,503 responses have been collected. Conclusions Based on international collaboration, the Canadian version of the WMH-ICS survey incorporates a novel methodological approach centered on the weekly administration of a comprehensive cross-sectional survey to independent stratified random samples of university students. After 27 months of consecutive survey administration, we have developed and refined a survey protocol that has proven effective in engaging students at four Canadian institutions, allowing us to track how mental health and substance use vary over time using an internationally developed university student survey based on the criteria from the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition).

BACKGROUND The World Health Organization (WHO) World Mental Health-International College Student (WMH-ICS) initiative aims to screen for mental health and substance use problems among post-secondary students on a global scale as well as to develop and evaluate evidence-based preventive and ameliorative interventions for this population. The epidemiologic surveys—a core component of the WMH-ICS initiative—are self-administered online questionnaires that generate diagnostic estimates for a wide range of common mental disorders and have been administered to over 95,000 students across 16 countries around the world. This protocol paper presents the Canadian version of the WMH-ICS survey, detailing the adapted survey instrument, the unique weekly cross-sectional administration, the multi-tiered recruitment strategy, and the associated risk mitigation protocols. OBJECTIVE This paper aims to provide a methodological resource for researchers conducting cross-national comparisons of WMH-ICS data, as well as to serve as a useful guide for those interested in replicating the outlined cross-sectional methodology to better understand how mental health and substance use vary over time among university students.

RESULTS In February 2020, the Canadian survey was deployed at the University of British Columbia. This was followed by deployment at Simon Fraser University (November 2020) and McMaster University (January 2021). Additional Canadian sites are currently in various stages of assessment and implementation. As of November 18th 2021, 21,143 responses have been collected. CONCLUSIONS The Canadian version of the WMH-ICS survey is based on a novel methodological approach centered on the weekly administration of a comprehensive cross-sectional survey to independent stratified random samples of university students. After 22 months of consecutive survey administration, we have developed and refined a survey protocol that has proven effective in engaging students at three Canadian institutions, allowing us to track how mental health and substance use vary over time using an internationally developed university student survey based on DSM-5 criteria.

Evidence about the impact of the COVID-19 pandemic on the mental health of specific subpopulations- such as university students-is needed as communities prepare for future waves.To study the association of proximity of COVID-19 with symptoms of anxiety and depression in university students.This trend study analyzed weekly cross-sectional surveys of probabilistic samples of students from the University of British Columbia for 13 weeks through the first wave of COVID-19. The main variable assessed was propinquity of COVID-19, defined as "knowing someone who tested positive for COVID-19", which was specified at different levels: knowing someone anywhere globally, in Canada, in Vancouver, in their course, or at home. Proximity was included in multivariable linear regressions to assess its association with primary outcomes, including 30-day symptoms of anxiety and/or depression.Of 1,388 respondents (adjusted response rate=50%), 5.6% knew someone with COVID-19 in Vancouver, 0.8% in their course, and 0.3% at home. Ten percent were overwhelmed and unable to access help. Knowing someone in Vancouver was associated with an 11 percentage-point increase in the probability of 30-day anxiety symptoms (SE=0,05; p≤0,05), moderated by gender, with a significant interaction of the exposure and being female (coefficient= 20(SE=0,09), p≤0,05). No association was found with depressive symptoms.Propinquity of COVID-19 cases may increase the likelihood of anxiety symptoms in students, particularly amongst men. Most students report coping well, but additional supports are needed for an emotionally overwhelmed minority who report being unable to access help.
