Value of Engagement in Digital Health Technology Research: Evidence Across 6 Unique Cohort Studies.

BACKGROUND: Wearable digital health technologies and mobile apps (personal digital health technologies [DHTs]) hold great promise for transforming health research and care. However, engagement in personal DHT research is poor. OBJECTIVE: The objective of this paper is to describe how participant engagement techniques and different study designs affect participant adherence, retention, and overall engagement in research involving personal DHTs. METHODS: Quantitative and qualitative analysis of engagement factors are reported across 6 unique personal DHT research studies that adopted aspects of a participant-centric design. Study populations included (1) frontline health care workers; (2) a conception, pregnant, and postpartum population; (3) individuals with Crohn disease; (4) individuals with pancreatic cancer; (5) individuals with central nervous system tumors; and (6) families with a Li-Fraumeni syndrome affected member. All included studies involved the use of a study smartphone app that collected both daily and intermittent passive and active tasks, as well as using multiple wearable devices including smartwatches, smart rings, and smart scales. All studies included a variety of participant-centric engagement strategies centered on working with participants as co-designers and regular check-in phone calls to provide support over study participation. Overall retention, probability of staying in the study, and median adherence to study activities are reported. RESULTS: The median proportion of participants retained in the study across the 6 studies was 77.2% (IQR 72.6%-88%). The probability of staying in the study stayed above 80% for all studies during the first month of study participation and stayed above 50% for the entire active study period across all studies. Median adherence to study activities varied by study population. Severely ill cancer populations and postpartum mothers showed the lowest adherence to personal DHT research tasks, largely the result of physical, mental, and situational barriers. Except for the cancer and postpartum populations, median adherences for the Oura smart ring, Garmin, and Apple smartwatches were over 80% and 90%, respectively. Median adherence to the scheduled check-in calls was high across all but one cohort (50%, IQR 20%-75%: low-engagement cohort). Median adherence to study-related activities in this low-engagement cohort was lower than in all other included studies. CONCLUSIONS: Participant-centric engagement strategies aid in participant retention and maintain good adherence in some populations. Primary barriers to engagement were participant burden (task fatigue and inconvenience), physical, mental, and situational barriers (unable to complete tasks), and low perceived benefit (lack of understanding of the value of personal DHTs). More population-specific tailoring of personal DHT designs is needed so that these new tools can be perceived as personally valuable to the end user.

The digital redesign of mental health: leveraging connected digital technologies for agency-driven patient-focused care.

Digital psychiatry could empower individuals to navigate their context-specific experiences outside healthcare visits. This editorial discusses how leveraging digital health technologies could dramatically transform how we conceptualise mental health and the mental health professional's day-day practice, and how patients could be enabled to navigate their mental health with greater agency.

The Post-Roe Political Landscape Demands a Morality of Caution for Women's Health.

The recent Supreme Court decision (ie, Dobbs v. Jackson Women's Health Organization), revoking the constitutional right to abortion in the United States, has the potential to dramatically disrupt progress in women's health research. The typical safeguards to ensure confidentiality and privacy of research participants in studies that collect certain types of personal health information may not hold against criminal investigations surrounding suspected pregnancy terminations. There are additional risks to participants in digital health research studies involving the use of wearable devices capable of tracking physiological measures, such as body temperature and heart rate, as these have shown promise for tracking conception and could be used to identify pregnancy termination signatures. There are strategies researchers can use to protect the safety of participants in health research who could get pregnant, while also maintaining integrity of research methods. The objective of this viewpoint is to discuss potential strategies to protect research participants' privacy that include the minimization of nonessential sensitive personal health information and anonymization protocols in the event of miscarriage or termination of pregnancy. We invite others to join this discussion so as to not let the current political landscape impede progress in women's health and reproductive research, while also protecting research participants.

The True Colours Remote Symptom Monitoring System: A Decade of Evolution.

The True Colours remote mood monitoring system was developed over a decade ago by researchers, psychiatrists, and software engineers at the University of Oxford to allow patients to report on a range of symptoms via text messages, Web interfaces, or mobile phone apps. The system has evolved to encompass a wide range of measures, including psychiatric symptoms, quality of life, and medication. Patients are prompted to provide data according to an agreed personal schedule: weekly, daily, or at specific times during the day. The system has been applied across a number of different populations, for the reporting of mood, anxiety, substance use, eating and personality disorders, psychosis, self-harm, and inflammatory bowel disease, and it has shown good compliance. Over the past decade, there have been over 36,000 registered True Colours patients and participants in the United Kingdom, with more than 20 deployments of the system supporting clinical service and research delivery. The system has been adopted for routine clinical care in mental health services, supporting more than 3000 adult patients in secondary care, and 27,263 adolescent patients are currently registered within Oxfordshire and Buckinghamshire. The system has also proven to be an invaluable scientific resource as a platform for research into mood instability and as an electronic outcome measure in randomized controlled trials. This paper aimed to report on the existing applications of the system, setting out lessons learned, and to discuss the implications for tailored symptom monitoring, as well as the barriers to implementation at a larger scale.

Daily and weekly mood ratings using a remote capture method in high-risk offspring of bipolar parents: Compliance and symptom monitoring.

OBJECTIVES: To determine the compliance and clinical utility of weekly and daily electronic mood symptom monitoring in adolescents and young adults at risk for mood disorder. METHODS: Fifty emerging adult offspring of bipolar parents were recruited from the Flourish Canadian high-risk offspring cohort study along with 108 university student controls. Participants were assessed by KSADS/SADS-L semi-structured interviews and used a remote capture method to complete weekly and daily mood symptom ratings using validated scales for 90 consecutive days. Hazard models and generalized estimating equations were used to determine differences in summary scores and regularity of ratings. RESULTS: Seventy-eight and 77% of high-risk offspring and 97% and 93% of controls completed the first 30 days of weekly and daily ratings, respectively. There were no differences in drop-out rates between groups over 90 days (weekly P = 0.2149; daily P = 0.9792). There were no differences in mean summary scores or regularity of weekly anxiety, depressive or hypomanic symptom ratings between high-risk offspring and control groups. However, high-risk offspring compared to controls had daily ratings indicating lower positive affect, higher negative affect and lower self-esteem (P = 0.0317). High-risk offspring with remitted mood disorder compared to those without had more irregularity in weekly anxiety and depressive symptom ratings and daily ratings of lower positive affect, higher negative affect, and higher shame and self-doubt (P = 0.0365). CONCLUSIONS: Findings support that high-resolution electronic mood tracking may be a feasible and clinically useful approach in monitoring emerging psychopathology in young people at high-risk offspring of mood disorder onset or recurrence.

The Cumulative Incidence of Self-Reported Suicide-Related Thoughts and Attempts in Young Canadians.

OBJECTIVE: To estimate the cumulative incidence of self-reported suicide-related thoughts (SRTs) and suicide attempts (SAs) in males and females from 11 to 25 years of age in Canada. METHODS: A cohort study was conducted by linking cycles 2 to 8 from the National Longitudinal Survey of Children and Youth, a representative survey of Canadians aged 11 to 25 years conducted from 1996 to 2009. The 11- to 25-year cumulative incidence of self-reported SRTs and SAs (with suicidal intent) was estimated in males and females using a novel application of a counting process approach to account for discontinuous risk intervals between survey cycles. RESULTS: The risk of SRTs was 29% (95% confidence interval [CI], 26% to 31%) in females and 19% (95% CI, 16% to 23%) in males. The risk of SAs was 16% (95% CI, 14% to 19%) in females and 7% (95% CI, 6% to 8%) in males. Over 70% of SRTs and SAs first occur between 11 and 16 years of age and 30% between 11 and 13 years of age, respectively. CONCLUSIONS: The risk of SRTs and SAs is high in young Canadians, with most events first occurring in early to mid-adolescence and possibly earlier. Females are at a higher risk compared to males. This research underscores the need for better longitudinal surveillance of SRTs and SAs in the population. A counting process framework could be useful for future research using existing longitudinal surveys suffering from design limitations relating to gaps in respondent follow-up. Furthermore, these findings have implications for younger SRT and SA risk management by clinicians and earlier implementation of suicide prevention programs.

Coping strategies and self-esteem in the high-risk offspring of bipolar parents.

OBJECTIVES: This study investigated whether there were differences in coping strategies and self-esteem between offspring of parents with bipolar disorder (high-risk) and offspring of unaffected parents (control), and whether these psychological factors predicted the onset and recurrence of mood episodes. METHODS: High-risk and control offspring were followed longitudinally as part of the Flourish Canadian high-risk bipolar offspring cohort study. Offspring were clinically assessed annually by a psychiatrist using semi-structured interviews and completed a measure of coping strategies and self-esteem. RESULTS: In high-risk offspring, avoidant coping strategies significantly increased the hazard of a new onset Diagnostic and Statistical Manual of Mental Disorders, 4th Edition twice revised mood episode or recurrence (hazard ratio: 1.89, p = 0.04), while higher self-esteem significantly decreased this hazard (hazard ratio: 2.50, p < 0.01). Self-esteem and avoidant coping significantly interacted with one another ( p < 0.05), where the risk of a Diagnostic and Statistical Manual of Mental Disorders, 4th Edition twice revised new onset mood episode or recurrence was only significantly increased among high-risk offspring with both high avoidant coping and low self-esteem. CONCLUSION: A reduction of avoidant coping strategies in response to stress and improvement of self-esteem may be useful intervention targets for preventing the new onset or recurrence of a clinically significant mood disorder among individuals at high familial risk.

Exposure to maternal depressive symptoms in childhood and suicide-related thoughts and attempts in Canadian youth: test of effect-modifying factors.

PURPOSE: To (1) determine the association between exposure to maternal depressive symptoms in childhood and offspring suicide-related thoughts (SRT) and attempts (SA) in youth and young adults and (2) identify effect measure modifiers (offspring sex, family structure, maternal perceived social support, and social cohesion) of the association in 1. METHOD: A cohort was constructed by linking all cycles from the National Longitudinal Survey of Children and Youth, a Canadian nationally representative survey, from 1994 to 2009 in 16,903 subjects 0 to 25 years. Exposure to maternal-reported depressive symptoms was measured when offspring were between 0 and 10 years. Offspring self-reported incident and recurrent SRT and SA were measured between 11 and 25 years. Time-to-event models under a counting process framework were used to estimate adjusted hazard ratios (HR) and relative rates (RR) and 95% confidence intervals (CI). Effect measure modifiers were examined across adjusted stratum-specific estimates. RESULTS: In offspring exposed to maternal depressive symptoms, the adjusted rates of incident SRT and SA (HR: 1.67, 95% CI 1.37, 2.08; HR: 1.93, 95% CI 1.43, 2.50) and of recurrent SRT and SA (RR: 1.61, 95% CI 1.33, 1.96; RR: 1.87, 95% CI 1.40, 2.36) were significantly elevated compared to non-exposed offspring. The stratum-specific rates of incident and recurrent SRT and SA were significantly elevated in females but not in males. CONCLUSIONS: Girls exposed to maternal depressive symptoms in childhood are a target group for childhood suicide preventive strategies. Family-based preventions, and strategies to identify and effectively treat maternal depressive episodes could be beneficial for suicide prevention in offspring.

Efficacy and tolerability of lithium for the treatment of acute mania in children with bipolar disorder: A systematic review: A report from the ISBD-IGSLi joint task force on lithium treatment.

OBJECTIVES: To assess the efficacy and tolerability of lithium for the treatment of acute mania in children and adolescent diagnosed with bipolar disorder. METHODS: A systematic literature search up to August 2017 was conducted for clinical trials that included lithium in males and females up to 18 years of age with a diagnosis of bipolar disorder and experiencing a manic or mixed episode according to standardized diagnostic criteria. The protocol was registered in PROSPERO (CRD42017055675). RESULTS: Four independent studies described in seven manuscripts met the inclusion criteria. Overall, 176 patients were treated with lithium either as a monotherapy or adjunct to risperidone. Efficacy results suggest that lithium may be superior to placebo (standardized mean difference [SMD] -0.42, 95% confidence interval [CI] -0.88 to 0.04), comparable to sodium divalproex (SMD -0.07, 95% CI: -0.31 to 0.18), but significantly less effective than risperidone for treating protracted manic/mixed episodes and comorbid attention-deficit hyperactivity disorder (ADHD) in prepubertal children (SMD 0.85, 95% CI: 0.54 to 1.15). Lithium was not associated with serious adverse events, and was generally well tolerated with common side effects similar to those reported in adults. CONCLUSIONS: Limited data suggests that lithium may be an effective and tolerable treatment for some forms of paediatric mania. However, lithium is clearly inferior in efficacy to risperidone in prepubertal patients diagnosed with protracted manic/mixed episodes and comorbid ADHD. There is a lack of data concerning the efficacy and tolerability of lithium as an acute treatment for classical mania in adolescents and important clinical issues remain unaddressed.

Suicidal Ideation vs. Suicide Attempts: Clinical and Psychosocial Profile Differences Among Depressed Patients: A Study on Personality Traits, Psychopathological Variables, and Sociodemographic Factors in 228 Patients.

This study investigated whether personality traits, psychopathological characteristics, and sociodemographic factors in depressed patients differentiate patients with only suicidal thoughts from those who have attempted suicide. We investigated two groups of patients with an affective disorder: 198 patients with a suicide attempt within the last 3 months (sex ratio male to female, 1:1.3; mean age male to female, 44.8/44.7 years) and 30 patients without a suicide attempt but with suicidal thoughts (sex ratio male to female, 1:2; mean age male to female, 39.4/42.6 years) using a comprehensive measurement (Mini-International Neuropsychiatric Interview, Structured Clinical Interview for DSM-4 Axis II disorders, Hamilton Depression Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, Hamilton Anxiety Scale, Brief Psychiatric Rating Scale, Clinical Global Impression Scale, Beck-Hopelessness Scale, Scale for Suicide Ideation, Impulsivity Rating Scale, Barratt Impulsivity Scale, Inventory for the Assessment of Aggression Factors, State-Trait Anger Expression Inventory, Ways of Coping Checklist). Several differences distinguished the two groups, namely, in personality traits such as anxiety or coping strategies and sociodemographics (e.g., education level). Personality traits, psychopathological characteristics, and sociodemographic factors are useful tools for assessing suicidal risk. Our findings encourage us to suggest that clinicians pay particular attention to sociodemographic variables such as separation/divorce and a lower education level when conducting risk assessments on suicidal patients.

Candidate Risks Indicators for Bipolar Disorder: Early Intervention Opportunities in High-Risk Youth.

BACKGROUND: Psychiatric illnesses like bipolar disorder are increasingly understood to be neurodevelopmental disorders with clinical, psychological, and biological indicators recognizable long before the emergence of the full-blown syndromes. METHODS: This paper is a selective review of findings from studies of high-risk children of affected parents that inform the knowledge of illness risk and development markers of bipolar disorder. We specifically focus on candidate clinical, biological, and psychological risk indicators that could serve as targets for future early intervention and prevention studies. RESULTS: There is convergent evidence from prospective studies that bipolar disorder typically debuts as depressive episodes after puberty. In some high-risk children, sleep and anxiety disorders precede mood disorders by several years and reflect an increased vulnerability. An association between early exposure to adversity (eg, exposure to parental illness, neglect from mother) and increased risk of psychopathology may be mediated through increased stress reactivity evident at both behavioral and biological levels. Inter-related psychological processes including reward sensitivity, unstable self-esteem, rumination, and positive self-appraisal are risk factors for mood disorders. Disturbances in circadian rhythm and immune dysfunction are associated with mood disorders and may be vulnerability markers influenced by these other risk factors. CONCLUSIONS: There is accruing evidence of a number of measurable and potentially modifiable markers of vulnerability and developing illness in youth at familial risk for bipolar disorder. Longitudinal studies of multiple biological and psychological risk processes in high-risk offspring, both individually and together, will improve our understanding of illness onset and lead to the development of specific early interventions.

Dissecting the heterogeneity of "in the wild" stress from multimodal sensor data.

Stress is associated with numerous chronic health conditions, both mental and physical. However, the heterogeneity of these associations at the individual level is poorly understood. While data generated from individuals in their day-to-day lives "in the wild" may best represent the heterogeneity of stress, gathering these data and separating signals from noise is challenging. In this work, we report findings from a major data collection effort using Digital Health Technologies (DHTs) and frontline healthcare workers. We provide insights into stress "in the wild", by using robust methods for its identification from multimodal data and quantifying its heterogeneity. Here we analyze data from the Stress and Recovery in Frontline COVID-19 Workers study following 365 frontline healthcare workers for 4-6 months using wearable devices and smartphone app-based measures. Causal discovery is used to learn how the causal structure governing an individual's self-reported symptoms and physiological features from DHTs differs between non-stress and potential stress states. Our methods uncover robust representations of potential stress states across a population of frontline healthcare workers. These representations reveal high levels of inter- and intra-individual heterogeneity in stress. We leverage multiple stress definitions that span different modalities (from subjective to physiological) to obtain a comprehensive view of stress, as these differing definitions rarely align in time. We show that these different stress definitions can be robustly represented as changes in the underlying causal structure on and off stress for individuals. This study is an important step toward better understanding potential underlying processes generating stress in individuals.

Validation of UK Biobank data for mental health outcomes: A pilot study using secondary care electronic health records.

UK Biobank (UKB) is widely employed to investigate mental health disorders and related exposures; however, its applicability and relevance in a clinical setting and the assumptions required have not been sufficiently and systematically investigated. Here, we present the first validation study using secondary care mental health data with linkage to UKB from Oxford - Clinical Record Interactive Search (CRIS) focusing on comparison of demographic information, diagnostic outcome, medication record and cognitive test results, with missing data and the implied bias from both resources depicted. We applied a natural language processing model to extract information embedded in unstructured text from clinical notes and attachments. Using a contingency table we compared the demographic information recorded in UKB and CRIS. We calculated the positive predictive value (PPV, proportion of true positives cases detected) for mental health diagnosis and relevant medication. Amongst the cohort of 854 subjects, PPVs for any mental health diagnosis for dementia, depression, bipolar disorder and schizophrenia were 41.6%, and were 59.5%, 12.5%, 50.0% and 52.6%, respectively. Self-reported medication records in UKB had general PPV of 47.0%, with the prevalence of frequently prescribed medicines to each typical mental health disorder considerably different from the information provided by CRIS. UKB is highly multimodal, but with limited follow-up records, whereas CRIS offers a longitudinal high-resolution clinical picture with more than ten years of observations. The linkage of both datasets will reduce the self-report bias and synergistically augment diverse modalities into a unified resource to facilitate more robust research in mental health.

Predicting the risk and timing of major mood disorder in offspring of bipolar parents: exploring the utility of a neural network approach.

BACKGROUND: Bipolar disorder onset peaks over early adulthood and confirmed family history is a robust risk factor. However, penetrance within families varies and most children of bipolar parents will not develop the illness. Individualized risk prediction would be helpful for identifying those young people most at risk and to inform targeted intervention. Using prospectively collected data from the Canadian Flourish High-risk Offspring cohort study available in routine practice, we explored the use of a neural network, known as the Partial Logistic Artificial Neural Network (PLANN) to predict the time to diagnosis of major mood disorders in 1, 3 and 5-year intervals. RESULTS: Overall, for predictive performance, PLANN outperformed the more traditional discrete survival model for 3-year and 5-year predictions. PLANN was better able to discriminate or rank individuals based on their risk of developing a major mood disorder, better able to predict the probability of developing a major mood disorder and better able to identify individuals who would be diagnosed in future time intervals. The average AUC achieved by PLANN for 5-year prediction was 0.74, which indicates good discrimination. CONCLUSIONS: This evaluation of PLANN is a useful step in the investigation of using neural networks as tools in the prediction of mood disorders in at-risk individuals and the potential that neural networks have in this field. Future research is needed to replicate these findings in a separate high-risk offspring sample.

Stress-related consequences of the coronavirus disease 2019 pandemic on symptoms of Crohn's disease.

OBJECTIVES: A link between stress and Crohn's disease activity suggests an association, but results have been conflicting. The purpose of this study was to assess whether the stress related to the coronavirus disease 2019 (COVID-19) pandemic affected disease activity in patients with Crohn's disease. BASIC METHODS: An anonymous survey was distributed to patients through gastroenterology clinics and networks. Patients were asked to report their Crohn's disease symptoms in the months prior to the COVID-19 pandemic and again during the early stages of the COVID-19 pandemic using the Manitoba inflammatory bowel disease index in addition to questions about stress, perception of reasons for symptom change and personal impact. MAIN RESULTS: Out of 243 individuals with a confirmed diagnosis of Crohn's disease, there was a 24% relative increase in active symptoms between the pre-COVID-19 period to the during-COVID-19 period (P < 0.0001) reflecting an absolute change from 45 to 56%, respectively. The most frequent reported reason for a change in symptoms was 'Increased stress/and or feeling overwhelmed' (118/236), and personal impact of the pandemic was, 'I'm worrying a lot about the future' (113/236), both reported by approximately half of respondents. PRINCIPAL CONCLUSIONS: This study serves as a 'proof of concept' demonstrating the impact of a significant and uniquely uniform stressor as a natural experiment on Crohn's disease activity. The severity of symptoms of Crohn's disease increased during the COVID-19 pandemic. The primary reported reason for symptom change was an increase in stress, not a change in diet, exercise or other lifestyle behaviours, corroborating the hypothesis that stress affects Crohn's disease activity.

Development and validation of a risk calculator for major mood disorders among the offspring of bipolar parents using information collected in routine clinical practice.

BACKGROUND: Family history is a significant risk factor for bipolar disorders (BD), but the magnitude of risk varies considerably between individuals within and across families. Accurate risk estimation may increase motivation to reduce modifiable risk exposures and identify individuals appropriate for monitoring over the peak risk period. Our objective was to develop and independently replicate an individual risk calculator for bipolar spectrum disorders among the offspring of BD parents using data collected in routine clinical practice. METHODS: Data from the longitudinal Canadian High-Risk Offspring cohort study collected from 1996 to 2020 informed the development of a 5 and 10-year risk calculator using parametric time-to-event models with a cure fraction and a generalized gamma distribution. The calculator was then externally validated using data from the Lausanne-Geneva High-Risk Offspring cohort study collected from 1996 to 2020. A time-varying C-index by age in years was used to estimate the probability that the model correctly classified risk. Bias corrected estimates and 95% confidence limits were derived using a jackknife resampling approach. FINDINGS: The primary outcome was age of onset of a major mood disorder. The risk calculator was most accurate at classifying risk in mid to late adolescence in the Canadian cohort (n = 285), and a similar pattern was replicated in the Swiss cohort (n = 128). Specifically, the time-varying C-index indicated that there was approximately a 70% chance that the model would correctly predict which of two 15-year-olds would be more likely to develop the outcome in the future. External validation within a smaller Swiss cohort showed mixed results. INTERPRETATION: Findings suggest that this model may be a useful clinical tool in routine practice for improved individualized risk estimation of bipolar spectrum disorders among the adolescent offspring of a BD parent; however, risk estimation in younger high-risk offspring is less accurate, perhaps reflecting the evolving nature of psychopathology in early childhood. Based on external validation with a Swiss cohort, the risk calculator may not be as predictive in more heterogenous high-risk populations. FUNDING: The Canadian High-Risk Study has been funded by consecutive operating grants from the Canadian Institutes for Health Research, currently CIHR PJT Grant 152796 he Lausanne-Geneva high-risk study was and is supported by five grants from the Swiss National Foundation (#3200-040,677, #32003B-105,969, #32003B-118,326, #3200-049,746 and #3200-061,974), three grants from the Swiss National Foundation for the National Centres of Competence in Research project "The Synaptic Bases of Mental Diseases" (#125,759, #158,776, and #51NF40 - 185,897), and a grant from GlaxoSmithKline Clinical Genetics.

Mental health need of students at entry to university: Baseline findings from the U-Flourish Student Well-Being and Academic Success Study.

AIM: Transition to university is associated with unique stressors and coincides with the peak period of risk for onset of mental illness. Our objective in this analysis was to estimate the mental health need of students at entry to a major Canadian university. METHODS: After a student-led engagement campaign, all first year students were sent a mental health survey, which included validated symptom rating scales for common mental disorders. Rates of self-reported lifetime mental illness, current clinically significant symptoms and treatment stratified by gender are reported. The likelihood of not receiving treatment among those symptomatic and/or with lifetime disorders was estimated. RESULTS: Fifty-eight per cent of all first-year students (n = 3029) completed the baseline survey, of which 28% reported a lifetime mental disorder. Moreover, 30% of students screened positive for anxiety symptoms, 28% for depressive symptoms, and 18% for sleep problems with high rates (≅45%) of associated impairment. Only 8.5% of students indicated currently receiving any form of treatment. Females were more likely to report a lifetime diagnosis, anxiety and depressive symptoms, as well as current treatment. Over 25% of students reported lifetime suicidal thoughts and 6% suicide attempt(s). Current weekly binge drinking (25%) and cannabis use (11%) were common, especially in males. CONCLUSIONS: There is limited systematically collected data describing the mental health needs of young people at entry to university. Findings of this study underscore the importance of timely identification of significant mental health problems as part of a proactive system of effective student mental health care.
