School-based Mental Health Interventions Targeting Depression or Anxiety: A Meta-analysis of Rigorous Randomized Controlled Trials for School-aged Children and Adolescents

We need better ways to help students avoid the harms of stress: Results of a meta-analysis on the effectiveness of school-based stress management interventions

The level of psychological stress in children and adolescents has increased rapidly over the past decade. The aim of the present meta-analysis was to evaluate the effectiveness of school-based intervention programs targeting stress management and coping/resilience in school-aged children. The present study used more rigorous selection criteria than previous meta-analyses by only including randomized controlled trials to increase the validity of the meta-analysis. Fifty-five studies were selected for the analysis, including 66 comparisons in the case of stress and 47 comparisons in the case of coping/resilience outcomes. A meta-regression with robust variance estimation was used. Effects were calculated as the standardized mean difference (Hedges' g) between the intervention and control conditions at posttest. The results highlighted important methodological issues and the influence of outliers. Without outliers, the results indicated a small significant overall effect on stress (g = -0.15, p < .01) and coping/resilience (g = 0.14, p = .01). When outliers were included, the effect sizes markedly increased in both cases (gstress = -0.26, p = .022; gcoping/resilience = 0.30, p = .009). Stress management interventions were more effective if they were delivered by mental health professionals or researchers than by teachers. Coping/resilience interventions were more effective in older age groups, in selective samples, and if they included cognitive behavioral therapy. An explanation of the results and a detailed discussion of the limitations of the study and its implications for practice are considered.

Study protocol for a pragmatic randomised multiple baseline trial evaluating Knowledge Insight Tools (KIT), a cognitive behavioural therapy-informed school-based counselling intervention for children and young people in UK secondary schools with low mood and anxiety

BACKGROUND

There is a pressing need to offer more accessible, evidence-based psychological interventions to secondary school students who are increasingly reporting difficulties with anxiety and low mood. The aim of this pragmatic randomised multiple baseline trial is to evaluate the efficacy of a school-based counselling intervention called Knowledge Insight Tools (KIT) for reducing anxiety and low mood in UK secondary school students. KIT is a flexible intervention delivered individually and informed by cognitive behavioural therapy (CBT).

METHODS

We will use a randomised multiple baseline design whereby young people will be randomly allocated to a baseline wait period of 3, 4, 5, 6, 7, or 8 weekly measurements, followed by receiving up to 10 weekly sessions of KIT delivered by trained, school-based practitioners. We aim to recruit 60 young people aged 11-18 who are primarily experiencing problems with low mood and/or anxiety from secondary schools across England and Scotland. We will assess child-reported anxiety, mood, and general psychological distress/coping with the Young Person's Clinical Outcomes in Routine Evaluation (YP-CORE), recorded at each session during the baseline and intervention phases. We will also assess child-reported anxiety and low mood with the Revised Children's Anxiety and Depression Scale (RCADS) at the beginning and end of treatment; practitioner-reported treatment fidelity with the KIT Fidelity Checklist; and practitioner-reported feasibility with an end-of-treatment Implementation Survey. We will analyse within-person and between-person change in YP-CORE scores across the baseline and intervention phases using visual analysis and piecewise multilevel growth curve models. We will also analyse pre-post changes in YP-CORE scores using randomisation tests, and reliable and clinically significant change using the RCADS scores.

DISCUSSION

The KIT trial is a pragmatic, randomised multiple baseline trial aimed at evaluating a school-based, individual CBT counselling intervention for reducing anxiety and low mood in UK secondary school students. Results will directly inform the provision of KIT in school-based counselling services, as well as the growing evidence-base for school-based CBT interventions.

Expanding Access to Mental Health: Evaluating the Potential of a Serious Mental Health Game for Adolescents

Digital technologies are important for expanding access to mental health support in low-resource settings. The current study tests the feasibility of a blended learning mental health intervention that was implemented for adolescents in Lebanon (N = 1,234), most of whom were Syrian refugees. The intervention features a digital game called The Helping Hand, which teaches adolescents how to respond to psychosocial challenges healthily and develop effective coping strategies. The blended learning intervention was tested using a single-arm, non-blinded, mixed-methods approach, through the analysis of pre-post questionnaires and key informant interviews. Results showed that the intervention was well accepted and popular among participating adolescents and the team that implemented it. After completing the intervention, adolescents showed a significant decrease in anxiety and depression symptoms and a significant increase in overall well-being. The feasibility and potential impact observed in this study demonstrate the benefits of continuing to refine and expand digital interventions that improve access to mental health support for vulnerable populations.

Long-Term Effects of Internet-Based Cognitive Behavioral Therapy on Depression Prevention Among University Students: Randomized Controlled Factorial Trial

Background

Internet-based cognitive behavioral therapy (iCBT) shows promise in the prevention of depression. However, the specific iCBT components that contribute to its effectiveness remain unclear.

Objective

We aim to evaluate the effects of iCBT components in preventing depression among university students.

Methods

Using a smartphone cognitive behavioral therapy (CBT) app, we randomly allocated university students to the presence or absence of 5 different iCBT components: self-monitoring, behavioral activation, cognitive restructuring, assertiveness training, and problem-solving. The active intervention lasted 8 weeks but the app remained accessible through the follow-up. The primary outcome was the onset of a major depressive episode (MDE) between baseline and the follow-up after 52 weeks, as assessed with the computerized World Health Organization Composite International Diagnostic Interview. Secondary outcomes included changes in the 9-item Patient Health Questionnaire, 7-item General Anxiety Disorder, and CBT Skills Scale.

Results

During the 12-month follow-up, 133 of 1301 (10.22%) participants reported the onset of an MDE. There were no significant differences in the incidence of MDEs between the groups with or without each component (hazard ratios ranged from 0.85, 95% CI 0.60-1.20, for assertiveness training to 1.26, 95% CI 0.88-1.79, for self-monitoring). Furthermore, there were no significant differences in the changes on the 9-item Patient Health Questionnaire, 7-item General Anxiety Disorder, or for CBT Skills Scale between component allocation groups. However, significant reductions in depression and anxiety symptoms were observed among all participants at the 52-week follow-up.

Conclusions

In this study, we could not identify any specific iCBT components that were effective in preventing depression or the acquisition of CBT skills over the 12-month follow-up period, but all participants with and without intervention of each iCBT component demonstrated significant improvements in depressive and anxiety symptoms. Further research is needed to explore the potential impact of frequency of psychological assessments, nonspecific intervention effects, natural change in the mental state, and the baseline depression level.

Brief Educational Workshops in Secondary Schools Trial (BESST): a cluster randomised controlled trial. Secondary analysis in those with elevated symptoms of depression

BACKGROUND

Depression and anxiety are increasingly prevalent in adolescents. The Brief Educational Workshops in Secondary Schools Trial investigated the effectiveness of a brief self-referral stress workshop programme for sixth-form students aged 16-18 years old.

OBJECTIVE

This study conducted a secondary analysis on the outcomes of participants with elevated depressive symptoms at baseline.

METHODS

This is an England-wide, multicentre, cluster randomised controlled trial to evaluate the clinical effectiveness and cost-effectiveness of a brief cognitive-behavioural therapy workshop (DISCOVER) compared with treatment-as-usual (TAU) (1:1). The primary outcome was depression symptoms (Mood and Feelings Questionnaire (MFQ)) at 6-month follow-up, using the intention-to-treat (ITT) population and analysed with a multilevel linear regression estimating a between-group adjusted mean difference (aMD). Cost-effectiveness, taking a National Health Service (NHS) and personal social services perspective, was explored using quality-adjusted life years (QALYs).

FINDINGS

Between 4 October 2021 and 10 November 2022, 900 adolescents at 57 schools were enrolled. 314 students were identified as having elevated symptoms of depression at baseline (>27 on MFQ). In this prespecified subgroup, the DISCOVER arm included 142 participants and TAU included 172. ITT analysis included 298 participants. Primary analysis at 6 months found aMD to be -3.88 (95% CI -6.48, -1.29; Cohen's d=-0.52; p=0.003), with a similar reduction at 3 months (aMD=-4.00; 95% CI -6.58, -1.42; Cohen's d=0.53; p=0.002), indicating a moderate, clinically meaningful effect in the DISCOVER arm. We found an incremental cost-effectiveness ratio of £5255 per QALY, with a probability of DISCOVER being cost-effective at between 89% and 95% compared with TAU.

CONCLUSIONS AND CLINICAL IMPLICATIONS

DISCOVER is clinically effective and cost-effective in those with elevated depressive symptoms. This intervention could be used as an early school-based intervention by the NHS.

The Impact of COVID on Adolescent Anxiety: Trends, Clinical Considerations, and Treatment Recommendations

Rates of clinical anxiety have increased during COVID and post-quarantine in youth, with older adolescent girls and youth with minorized racial, gender, and sexuality identities most vulnerable. Given that increased anxiety to a threatening/uncertain environment is adaptive, it is important to conceptualize anxiety from a balanced perspective, evaluating its functionality. For adolescents continuing to struggle with re-integration into their social environments and school avoidance, an exposure framework is necessary to encourage approach behaviors to recalibrate the social environment as safe. Disproportion between demand for services and available providers increased greatly due to the pandemic. Evidence-based treatments for anxiety can be delivered via telehealth, in school, or in primary care settings.

The Provision of Psychosocial Support to Students in Jordan: Teachers' Knowledge, Attitudes, Skills, Practices, and Perceived Barriers

BACKGROUND

Psychosocial support provision in schools is a promising strategy for overcoming barriers to accessing mental health care. This study aimed to assess teachers' knowledge, attitudes, practices, skills, and perceived barriers in providing psychosocial support to students in Jordan.

METHODS

The sample included teachers working in public schools, private schools, the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) schools, and Zaatari camp schools, as well as non-formal education centers. The study utilized a multi-stage stratified cluster sampling technique to select a nationally representative sample.

RESULTS

A total of 549 teachers were included, and only 25.2% have ever received mental health training. Most teachers reported a high level of good and acceptable knowledge of psychosocial support and had a positive attitude toward the provision of psychosocial support, however, about a quarter (25.5%) agreed on feeling nervous in discussing students' psychosocial problems with their parents or school administrators. The least enacted practice was the systematic engagement with parents, school administration, and other community resources in students' well-being (sometimes, 31.6%; rarely, 20.4%). Gaps in skills were mainly in communicating with external resources and parents. The main barriers included parents' misunderstanding of teachers' role in providing psychosocial support to students (56.8%), lack of integration of psychosocial support in the curriculum (55.6%), and challenges in identifying students with psychosocial problems due to large class sizes (54.3%).

CONCLUSION

The results show that gaps extend beyond the individual level of teachers to the community level. School-based psychosocial support interventions must consider the multiple factors that influence their implementation at multiple levels, including the individual, relational, community, and societal levels.

Effectiveness of a group psychological intervention to reduce psychosocial distress in adolescents in Pakistan: a single-blind, cluster randomised controlled trial

BACKGROUND

Emotional problems in adolescents living in low-income and middle-income countries (LMICs) remain largely unaddressed; key reasons include a scarcity of trained mental health professionals and unavailability of evidence-based, scalable psychological interventions. We aimed to evaluate the effectiveness of a non-specialist-delivered, group psychological intervention to reduce psychosocial distress in school-going adolescents in Pakistan.

METHODS

In a two-arm, single-blind, cluster randomised controlled trial, eligible public school clusters from a rural subdistrict of Gujar Khan, Rawalpindi, Pakistan, were randomised (1:1, stratified by sex) using permuted block randomisation into intervention (n=20) and wait-list control (n=20) groups. Adolescents aged 13-15 years who provided informed assent and caregivers' consent were screened for psychosocial distress using the youth-reported Pediatric Symptoms Checklist (PSC; total psychosocial distress scores from 0 to 70), and those scoring 28 or more and their caregivers were enrolled into the trial. Adolescents in the intervention group received seven weekly group sessions and their caregivers received three biweekly group sessions in school settings from trained non-specialists. The primary outcome was change from baseline in the total PSC scores at 3 months post-intervention. The trial was registered prospectively with the International Standard Randomised Controlled Trial Number registry, ISRCTN17755448.

FINDINGS

From the 40 school clusters that were included, 282 adolescents in the intervention group and 284 adolescents in the wait-list control group were enrolled between Nov 2 and Nov 30, 2021. At 3 months, adolescents in the intervention group had significantly lower mean total score on the PSC compared with adolescents in the control group (mean difference in change from baseline 3·48 [95% CI 1·66-5·29], p=0·0002, effect size 0·38 [95% CI 0·18-0·57]; adjusted mean difference 3·26 (95% CI 1·46-5·06], p=0·0004, effect size 0·35 (0·16-0·55). No adverse events were reported in either group.

INTERPRETATION

The group psychological intervention most likely represents a feasible and effective option for adolescents with psychosocial distress in school settings.

Clinical effectiveness and cost-effectiveness of a brief accessible cognitive behavioural therapy programme for stress in school-aged adolescents (BESST): a cluster randomised controlled trial in the UK

BACKGROUND

Depression and anxiety are increasingly prevalent in adolescents. The Brief Educational Workshops in Secondary Schools Trial investigated the effectiveness of a brief accessible stress workshop programme for 16-18-year-olds. We aimed to investigate the clinical effectiveness and cost-effectiveness of the DISCOVER cognitive behavioural therapy (CBT) workshop on symptoms of depression in 16-18-year-olds at 6 months compared with treatment-as-usual.

METHODS

We conducted a multicentre, cluster randomised controlled trial in UK schools or colleges with sixth forms to evaluate clinical effectiveness and cost-effectiveness of a brief CBT workshop (DISCOVER) compared with treatment-as-usual. We planned to enrol 60 schools and 900 adolescents, using a self-referral system to recruit participants. Schools were randomised in a 1:1 ratio for participants to receive either the DISCOVER workshop or treatment-as-usual, stratified by site and balanced on school size and index of multiple deprivation. Participants were included if they were 16-18 years old, attending for the full school year, seeking help for stress, and fluent in English and able to provide written informed consent. The outcome assessors, senior health economist, senior statistician, and chief investigator were masked. People with lived experience were involved in the study. The primary outcome was depression symptoms measured with the Mood and Feelings Questionnaire (MFQ) at 6-month follow-up, in the intention-to-treat population of all participants with full covariate data. The trial was registered with the ISRCTN registry (ISRCTN90912799).

FINDINGS

111 schools were invited to participate in the study, seven were deemed ineligible, and 47 did not provide consent. Between Oct 4, 2021, and Nov 10, 2022, 933 students at 57 schools were screened for eligibility, seven were not eligible for inclusion, and 26 did not attend the baseline meeting and assessment, resulting in 900 adolescents participating in the study. The DISCOVER group included 443 participants (295 [67%] female and 136 [31%] male) and the treatment-as-usual group included 457 participants (346 [76%] female and 92 [20%] male). 468 (52%) of the 900 participants were White, and the overall age of the participants was 17·2 years (SD 0·6). 873 (97%) adolescents were followed up in the intention-to-treat population. The primary intention-to-treat analysis (n=854) found an adjusted mean difference in MFQ of -2·06 (95% CI -3·35 to -0·76; Cohen's d=-0·17; p=0·0019) at the 6-month follow-up, indicating a clinical improvement in the DISCOVER group. The probability that DISCOVER is cost- effective compared with treatment-as-usual ranged from 61% to 78% at a £20 000 to £30 000 per quality-adjusted life-year threshold. Nine adverse events (two of which were classified as serious) were reported in the DISCOVER group and 14 (two of which were classified as serious) were reported in the treatment-as-usual group.

INTERPRETATION

Our findings indicate that the DISCOVER intervention is modestly clinically effective and economically viable and could be a promising early intervention in schools. Given the importance of addressing mental health needs early in this adolescent population, additional research is warranted to explore this intervention.

Effects of three prophylactic interventions on French middle-schoolers' mental health: protocol for a randomized controlled trial

Adolescence is a strategic developmental stage in terms of preventing later difficulties and ensuring good mental health. Prophylactic interventions, which are conducted before the onset, prolongation, or worsening of difficulties, and aim to prevent or reduce symptoms or to promote wellbeing, therefore appear particularly appropriate for adolescents. However, existing prophylactic interventions conducted with adolescents have several weaknesses, including sparse theoretical frameworks, ambivalent evidence of their efficacy, and implementation and dissemination difficulties. In addition, no data are currently available on the effectiveness of such interventions in France. To fill this gap, a four-arm randomized controlled trial will be performed to assess the effectiveness of three prophylactic interventions targeting reactive, proactive and interpersonal adaptation in fourth-grade middle-school students, together with participants' experience and perception of the interventions. Based on existing knowledge about adolescents, their learning mechanisms, and field constraints, these three interventions have been designed to promote their learning and receptiveness to interventions. Compared with baseline (i.e., before the intervention), we expect to observe a significant decrease in the level of distress (anxiety and depressive symptoms, functional impairment, and psychosocial difficulties) and a significant increase in the level of wellbeing after the intervention, across the three intervention groups, but not in the control group. In addition, we expect to observe post-intervention improvements in the processes targeted by the reactive adaptation intervention (operationalized as coping strategy use and flexibility), those targeted by the proactive adaptation intervention (operationalized as the tendency to engage in committed actions and general self-efficacy), and those targeted by the interpersonal adaptation intervention (operationalized as assertiveness in interactions), but only in the corresponding groups, with no change in any of these processes in the control group. The results of this research will not only enrich our knowledge of the processes involved in adolescents' distress and wellbeing, but also provide clues as to the best targets for intervention. Moreover, the material for these interventions will be freely available in French on request to the corresponding author, providing access to innovative and fully assessed interventions aimed at promoting adolescents' mental health in France.This clinical trial is currently being registered under no. 2023-A01973-42 on https://ansm.sante.fr/ . This is the first version of the protocol.

Academic Stress Interventions in High Schools: A Systematic Literature Review

The experience of academic stress is common during high school and can have significant negative consequences for students' educational achievement and wellbeing. High school students frequently report heightened levels of school-related distress, particularly as they approach high-stakes assessments. Programs designed to reduce or prevent academic stress are needed, and their delivery in school settings is ideal to improve treatment access. The current review aimed to examine the effectiveness of high school-based programs in reducing or preventing academic stress. A systematic search returned 31 eligible studies across 13 countries. Programs were categorised according to intervention type, format, and facilitator. Results showed that the methodological quality of most studies was poor, and many used an inactive control group. As predicted by theories of academic stress, the strongest evidence was for programs grounded in cognitive-behavioural therapy (CBT). There was evidence that both universal and targeted approaches can be beneficial. The unique implementation issues for these two formats are discussed. Most programs were delivered by psychologists and were generally effective, but almost all of these were CBT programs. A smaller proportion of programs delivered by teachers were effective. Therefore, future studies should evaluate the implementation success of programs to improve the rate of effective delivery by school staff. Overall, the field will benefit from more randomised controlled trials with comparisons to active control groups, larger sample sizes and longer-term follow-ups.

Editorial: The need for more effective school-based youth mental health interventions

An important setting to detect youth mental health problems and provide interventions is the school context, but effective and affordable school-based interventions are scarce and implementation of the available evidence-based interventions is limited. In this editorial, we highlight three issues and propose a research agenda. First, we emphasize that many of the mental health interventions currently used in school settings lack a solid evidence base. Second, we outline that high-quality studies are needed to determine what works, for whom it works and under which circumstances. This includes insight into the most effective intervention elements, subgroups of students who profit more or less from these interventions, and the most effective modes of delivery. These questions should drive our research agenda on school-based mental health interventions. Finally, while answering these pivotal questions, a collaborative multidisciplinary effort should be made to implement school-based interventions with a solid evidence base, which involves, among others, studying how this can be done most effectively.

Piloting an Alternative Implementation Modality for a School-Based Child Sexual Abuse Prevention Curriculum

BACKGROUND

In the U.S., the most pervasive child sexual abuse (CSA) prevention strategy involves school-based prevention programs; however, the reach of these programs is limited due to implementation constraints, such as budgets or turnover. This is notable as standard delivery of often requires two facilitators in the classroom. Leveraging a natural experiment in the implementation of Safe Touches, the current study sought to explore the feasibility of implementation with a single facilitator using pre-recorded videos compared to the standard in-person delivery.

METHODS

A six-item CSA-related knowledge questionnaire was delivered to (N = 1480) second-graders post-workshop. An independent-samples t-test was used to compare the mean of CSA-related knowledge item responses for each delivery modality. Student-level data were paired with teacher evaluations and an interview with the facilitator.

RESULTS

Across workshops delivered in 25 schools, there was no significant difference in knowledge based on CSA-related questions by workshop modality. Teachers indicated the facilitators responded effectively to the children's questions and comments in both delivery modalities. Input from the facilitator was positive.

CONCLUSIONS

Triangulation of student knowledge, teacher input, and facilitator experience indicates the viability and feasibility of this implementation strategy for Safe Touches, and potentially other school-based CSA prevention programs. To ensure equitable access to the CSA prevention program, the empirical examination of, and investment in, alternative implementation options for school-based CSA preventive programs is encouraged.

Supporting Quality Integrated Care for Adolescent Depression in Primary Care: A Learning System Approach

Background

Quality integrated care, which involves primary care and mental health clinicians working together, can help identify and treat adolescent depression early. We explored systemic barriers to quality integrated care at the provincial level in Ontario, Canada using a learning system approach.

Methods

Two Ontario Health Teams (OHTs), regional networks designed to support integrated care, completed the Practice Integration Profile (PIP) and participated in focus groups.

Results

The OHTs had a median PIP score of 69 out of 100. Among the PIP domains, the lowest median score was case identification (50), and the highest one was workspace (100). The focus groups generated 180 statements mapped to the PIP domains. Workflow had the highest number of coded statements (59, 32.8%).

Discussion

While the primary care practices included mental health clinicians on-site, the findings highlighted systemic barriers with adhering to the integrated care pathway for adolescent depression. These include limited access to mental health expertise for assessment and diagnosis, long wait times for treatment, and shortages of clinicians trained in evidence-based behavioral therapies. These challenges contributed to the reliance on antidepressants as the first line of treatment due to their accessibility rather than evidence-based guidelines.

Conclusion

Primary care practices, within regional networks such as OHTs, can form learning systems to continuously identify the strategies needed to support quality integrated care for adolescent depression based on real-world data.

Can an Universal School-Based Social Emotional Learning Program Reduce Adolescents' Social Withdrawal and Social Anxiety?

There is a lack of studies analyzing if universal school-based Social and Emotional Learning programs can reduce social withdrawal and social anxiety. This study analyzed the effectiveness of one such program on those variables, and the role of individual school climate perceptions. In this nationwide study, 704 seventh to eighth-grade Portuguese students (Mage = 12.96, SD = 1.09, 48% girls), of which 215 (30.6%) in the comparison group, were assessed at pretest, post-test, and follow-up seven months later. Analyses showed positive intervention results in self- and teacher-reported social withdrawal and social anxiety. Regarding school climate, intervention group students with more positive teacher-student relationships benefitted more from program participation in social anxiety. These results support the program's effectiveness for addressing social withdrawal and social anxiety.

Efficacy and Effectiveness of Universal School-Based Wellbeing Interventions in Australia: A Systematic Review

The World Health Organisation defines health in terms of wellbeing, and wellbeing has become both a construct and a measure of impact in early intervention and prevention programs in schools. In Australia, schools report on their wellbeing initiatives and there is a plethora of government-funded wellbeing programs already in place in schools. However, education systems and stakeholders worldwide are facing significant challenges with mixed evaluation results of program impact and intervention effect. To better support students, schools, school-based healthcare workers, and community, it is important to know about the effectiveness of school-based programs; yet in the last decade, there has been no national appraisal of these programs in Australia. This systematic review aims to report on the effectiveness of Australian school-based wellbeing programs through a search of 13 databases. Out of 2888 articles, 29 met inclusion criteria. The results found that seventeen interventions comprising 80% of the total number of participants reported no statistically significant intervention effect on wellbeing outcomes. We argue that supporting wellbeing through robust program intervention is important as wellbeing presents both an indication of later onset of more serious mental health issues, and an opportunity for early intervention to break the trajectory leading to full disorder.

Visits to Alberta Emergency Departments for Child Mental Health Concerns During the COVID-19 Pandemic: An Examination of Visit Trends in Relation to School Closures and Reopenings

OBJECTIVE

We examined emergency department (ED) mental health visit trends by children in relation to periods of school closure and reopening during the COVID-19 pandemic in Alberta, Canada.

METHODS

Mental health visits by school-aged children (5 to <18 years) were extracted from the Emergency Department Information System, a province-wide database, from March 11, 2020, to November 30, 2021 (pandemic period; n = 18,997) and March 1, 2019, to March 10, 2020 (1-year, prepandemic comparator period; n = 11,540). We calculated age-specific visit rates and compared rate differences between periods of school closure (March 15-June 30, 2020; November 30, 2020-January 10, 2021; April 22-June 30, 2021) and reopening (September 4-November 29, 2020; January 11-April 21, 2021; September 3-November 30, 2021) to matched prepandemic periods. We used a ratio of relative risk to examine the risk of a visit during closures versus reopenings.

RESULTS

The cohort included 11,540 prepandemic visits and 18,997 pandemic visits. Compared with prepandemic periods, ED visit rates increased across all ages during the first (+85.53%; 95% confidence interval [CI], 73.68% to 100.41%) and third (+19.92%; 95% CI, 13.28% to 26.95%) school closures, and decreased during the second closure (-15.37%; 95% CI, -22.22% to -7.92%). During school reopenings, visit rates decreased across all ages during the first reopening (-9.30%; 95% CI, -13.94% to -4.41%) and increased during the third reopening (+13.59%; 95% CI, 8.13% to 19.34%); rates did not change significantly during the second reopening (2.54%; 95% CI, -3.45% to 8.90%). The risk of a visit during school closure versus reopening was only higher for the first closure with 2.06 times the risk (95% CI, 1.88 to 2.25).

CONCLUSIONS

Emergency department mental health visit rates were highest during the first school closure of the COVID-19 pandemic, and the risk of a visit during this closure period was twice compared with when schools first reopened.
