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).
RESULTS: 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: 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.

OBJECTIVE: The Dynamics of Family Conflict (FamC) prospective cohort study was set up to investigate how and why interparental conflicts and family relations develop over time, and in which contexts which types of conflicts and relations are most negative for which children. FamC focuses on the family within a scope spanning macrolevel as well as microlevel processes.
METHODS: Families were recruited from MoBa (pilot project) and family counselling offices across Norway when parents attended parental counselling, therapy or mandatory mediation in relation to parental relationship dissolution. All families were thus experiencing challenges and/or going through a family transition. Families were eligible for the study if parents had at least one joint child between 0 and 16 years. Both parents and up to five children from the same family could participate. A total of 2871 families were recruited (participation rate wave 1: 78%) and an estimated 55% of parents (based on wave 1 data) were divorced/separated. Additional data were obtained from therapists/mediators at the family counselling offices about the family, and childcare or schoolteachers provided data on the youngest (0-6 years) children.
RESULTS: Results show that interparental conflict patterns vary with family constellation. Interparental conflict severity is inversely related to the discrepancy between child-reported and parent-reported child reactions to interparental conflicts, and child-self-reported reactions are higher relative to parent-reported child reactions. Other findings show that family characteristics (eg, the number and age of children in the family and financial difficulties) are predictive of the type of residence arrangement that parents practice.
UNASSIGNED: The cohort is ideally suited for cross-cultural comparisons and further examination of family processes and dynamics including parent repartnering, step-parents and new family members, associations between different family constellations and child adjustment, and fathering, father-child relationship and child adjustment. There are plans for further follow-up data collection.

BACKGROUND: The association between paediatric traumatic brain injury (pTBI) and post-traumatic attention-deficit/hyperactivity disorder (ADHD) medication usage remains understudied subject.
OBJECTIVE: We aimed to evaluate the association between pTBI and subsequent ADHD medication.
METHODS: A nationwide retrospective cohort study in Finland from 1998 to 2018 included 66 594 patients with pTBI and 61 412 references with distal extremity fractures. ADHD medication data were obtained from the Finnish Social Insurance Institution. The primary outcome was post-traumatic pediatric ADHD medication. A 1-year washout period was applied, and follow-up started 1 year post-pTBI.
RESULTS: Kaplan-Meier analyses showed higher ADHD medication usage in patients with pTBI, especially post-operatively. Both sex groups exhibited elevated rates compared with the reference group. Over 10 years, cumulative incidence rates were 3.89% (pTBI) vs 1.90% (reference). HR for pTBI was 1.89 (95% CI 1.70 to 2.10) after 4 years and 6.31 (95% CI 2.80 to 14.20) for the operative group after the initial follow-up year. After 10 years, cumulative incidence in females increased to 2.14% (pTBI) vs 1.07% (reference), and in males, to 5.02% (pTBI) vs 2.35% (reference). HR for pTBI was 2.01 (95% CI 1.72 to 2.35) in females and 2.23 (95% CI 2.04 to 2.45) in males over 1-20 years.
CONCLUSIONS: A substantial association between pTBI and post-traumatic ADHD medication was evidenced over a 20-year follow-up period.
CONCLUSIONS: These results stress the need for preventive measures for pTBI and highlight the potential impact of long-term post-traumatic monitoring and psychoeducation.

BACKGROUND: Depression and anxiety are common in adolescents and have increased over the last decade. During that period, smartphone usage has become ubiquitous.
OBJECTIVE: The study aim was to assess the association between problematic smartphone usage (PSU) and anxiety.
METHODS: Using a prospective mixed methods cohort study design, students aged 13-16 year old from two schools were enrolled regarding their smartphone use, mood and sleep via a semistructured questionnaire at baseline and week 4. The primary outcome was symptoms of anxiety (Generalised Anxiety Disorder Questionnaire, GAD-7) and exposure was PSU (Smartphone Addiction Scale Short Version). A linear regression was fitted to assess the change in anxiety. Thematic analysis of free-text responses was conducted.
RESULTS: The sample included 69 participants that were enrolled and followed up between 28 March and 3 June 2022. Of those with PSU, 44.4% exhibited symptoms of moderate to severe anxiety compared with 26.4% of those without PSU. There was a linear association between change in symptoms of anxiety and PSU β=0.18 (95% CI 0.04 to 0.32, p=0.013). Several themes were found: both positive and negative effects of smartphones on relationships; negative effects on school performance and productivity; mixed effects on mood; a desire to reduce the amount of time spent on smartphones.
CONCLUSIONS: Increased anxiety, depression and inability to sleep were seen in participants as their PSU score increased over time. Participants reported both positive and negative effects of smartphones and almost all used strategies to reduce use.
CONCLUSIONS: Interventions need to be developed and evaluated for those seeking support.

BACKGROUND: Children exposed to trauma are vulnerable to developing post-traumatic stress disorder (PTSD) and other adverse mental health outcomes. In low-and middle-income countries (LMICs), children are at increased risk of exposure to severe trauma and co-occurring adversities. However, relative to high-income countries, there is limited evidence of the factors that predict good versus poor psychological recovery following trauma exposure in LMIC children, and the role of caregiver support in these high-adversity communities.
METHODS: We will conduct a longitudinal, observational study of 250 children aged 8-16 years and their caregivers in South Africa, following child exposure to acute trauma. Dyads will be recruited from community hospitals following a potentially traumatic event, such as a motor vehicle accident or assault. Potential participants will be identified during their hospital visit, and if they agree, will subsequently be contacted by study researchers. Assessments will take place within 4 weeks of the traumatic event, with 3-month and 6-month follow-up assessments. Participants will provide a narrative description of the traumatic event and complete questionnaires designed to give information about social and psychological risk factors. Child PTSD symptoms will be the primary outcome, and wider trauma-related mental health (depression, anxiety, behavioural problems) will be secondary outcomes. Regression-based methods will be used to examine the association of psychosocial factors in the acute phase following trauma, including caregiver support and responding, with child PTSD and wider mental health outcomes.
BACKGROUND: Ethical approvals have been granted by Stellenbosch University and the University of Bath, with additional approvals to recruit via hospitals and healthcare clinics being granted by the University of Cape Town, the Department of Health and the City of Cape Town. Study findings will be disseminated via publication in journals, workshops for practitioners and policy-makers, and public engagement events.

BACKGROUND: Online-based interventions provide a low-threshold way to reach and support families. The mentalisation-based Lighthouse Parenting Programme is an established intervention aimed at preventing psychopathological development in children. The objective of this study is to examine the feasibility of an online adaptation of the Lighthouse Parenting Programme (LPP-Online), evaluating (a) recruitment capability, compliance, acceptability and satisfaction with the intervention; (b) the psychometric properties of and the acceptability regarding the adjunct psychological evaluation; and (c) the employed materials and resources. The study will also obtain a preliminary evaluation of participants\' responses to the intervention.
METHODS: In this monocentric, one-arm, non-randomised feasibility trial, n=30 psychologically distressed parents with children aged 0 to 14 years will participate in the LPP-Online for a duration of 8 weeks. The intervention consists of online group sessions and individual sessions, 38 smartphone-based ecological momentary interventions (EMI), and psychoeducational materials (website, booklet). At baseline (T0) and the end of the intervention (T1), parents complete self-report questionnaires as well as 7-day ecological momentary assessments (EMA) via smartphone. During the intervention, additional EMA are completed before and after the daily EMI. An interview regarding parents\' subjective experience with the intervention will be conducted at T1. The feasibility of the intervention, the psychological evaluation and the resources will be examined using descriptive and qualitative analyses. The preliminary evaluation of the parents\' response to the intervention will be conducted by analysing pre-post changes in questionnaire measures and the 7-day EMA as well as data of additional EMA completed before and after the daily EMI.
BACKGROUND: Ethical approval of the study has been obtained from the local ethics board (Faculty of Behavioural and Cultural Studies, University of Heidelberg). Consent to participate will be obtained before starting the assessments. Results will be disseminated as publications in peer-reviewed scientific journals and at international conferences.

BACKGROUND: Little is known about the social validity of self-harm prevention apps for young adolescents with severe mental health problems who repeatedly self-harm.
OBJECTIVE: We assessed the acceptability, use and safety of BlueIce, a self-harm prevention app for young adolescents who self-harm.
METHODS: Mixed methods study involving a content analysis of postuse interviews. Participants were a clinical group of 60 UK adolescents aged 12-17 with repeated self-harm, randomised to receive BlueIce.
RESULTS: BlueIce was used by 57/60 (95%) respondents with 47/57 (82%) using BlueIce when thinking about self-harm. 17/47 (36%) who were thinking about self-harm used it on more than six occasions with 36/47 (77%) reporting that BlueIce prevented at least one episode of self-harm. 33/47 (70%) reported occasions when they used the app but still went on to self-harm. Reasons why the app was not used or not helpful included feeling too distressed, a negative mindset, prior decision to self-harm or forgetting. BlueIce was rated 4.09 (SD=0.75) out of 5 stars, with high mean ratings out of 10 for ease of use (8.70, SD=1.37) and good for acceptability (7.68, SD=2.05) and helpfulness (6.77, SD=1.72). No respondent identified BlueIce as triggering any episode of self-harm.
CONCLUSIONS: These findings are consistent with previous evaluations and highlight the acceptability, use and safety of BlueIce. Self-reports indicate that BlueIce prevented some episodes of self-harm.
CONCLUSIONS: Our results highlight the acceptability of the BlueIce self-harm app for young adolescents who repeatedly self-harm.

BACKGROUND: Early childhood development forms the foundations for functioning later in life. Thus, accurate monitoring of developmental trajectories is critical. However, such monitoring often relies on time-intensive assessments which necessitate administration by skilled professionals. This difficulty is exacerbated in low-resource settings where such professionals are predominantly concentrated in urban and often private clinics, making them inaccessible to many. This geographic and economic inaccessibility contributes to a significant \'detection gap\' where many children who might benefit from support remain undetected. The Scalable Transdiagnostic Early Assessment of Mental Health (STREAM) project aims to bridge this gap by developing an open-source, scalable, tablet-based platform administered by non-specialist workers to assess motor, social and cognitive developmental status. The goal is to deploy STREAM through public health initiatives, maximising opportunities for effective early interventions.
METHODS: The STREAM project will enrol and assess 4000 children aged 0-6 years from Malawi (n=2000) and India (n=2000). It integrates three established developmental assessment tools measuring motor, social and cognitive functioning using gamified tasks, observation checklists, parent-report and audio-video recordings. Domain scores for motor, social and cognitive functioning will be developed and assessed for their validity and reliability. These domain scores will then be used to construct age-adjusted developmental reference curves.
BACKGROUND: Ethical approval has been obtained from local review boards at each site (India: Sangath Institutional Review Board; All India Institute of Medical Science (AIIMS) Ethics Committee; Indian Council of Medical Research-Health Ministry Screening Committee; Malawi: College of Medicine Research and Ethics Committee; Malawi Ministry of Health-Blantyre District Health Office). The study adheres to Good Clinical Practice standards and the ethical guidelines of the 6th (2008) Declaration of Helsinki. Findings from STREAM will be disseminated to participating families, healthcare professionals, policymakers, educators and researchers, at local, national and international levels through meetings, academic journals and conferences.

BACKGROUND: Loneliness has been identified as an important public health issue, peaking during adolescence. Previous research has suggested that social interaction is a key factor in loneliness, and positive social interaction can act as a protective factor against loneliness. However, it is unclear whether there are differing impacts of in-person and online social interaction on adolescents\' loneliness and mental health. Ecological Momentary Assessment (EMA) designs are ideally suited for better understanding these associations.
METHODS: In the \'Loneliness in the Digital World\' study, we will use a co-developed EMA design to capture daily social interactions, loneliness and mental health such as positive and negative emotions, depression and anxiety in approximately 200 adolescents aged 12-15 years. We will combine this with comprehensive information gathered from online surveys. Analysing the data using techniques such as dynamic structural equation modelling, we will examine, among other research questions, the associations between online and in-person social interaction and feelings of loneliness. The results can help inform interventions to support adolescents with high levels of loneliness and poor mental health.
BACKGROUND: We received the ethics approval for the data collection from The Academic and Clinical Central Office for Research and Development, followed by the College of Medicine and Veterinary Medicine Ethics panel at University of Edinburgh, and finally reviewed by East of Scotland Research Ethics Service. The results will be disseminated through journal publications, conferences and seminar presentations and to relevant stakeholders such as teachers.

BACKGROUND: Although adolescents make treatment gains in psychiatric residential treatment (RT), they experience significant difficulty adapting to the community and often do not sustain treatment gains long term. Their parents are often not provided with the necessary support or behaviour management skillset to bridge the gap between RT and home. Parent training, a gold standard behaviour management strategy, may be beneficial for parents of these youth and web-based parent training programmes may engage this difficult-to-reach population. This study focuses on a hybrid parent training programme that combines Parenting Wisely (PW), a web-based parent training with facilitated discussion groups (Parenting Wisely for Residential Treatment (PWRT)). This study aims to: (1) establish the feasibility and acceptability of PWRT, (2) evaluate whether PWRT engages target mechanisms (parental self-efficacy, parenting behaviours, social support, family function) and (3) determine the effects of PWRT on adolescent outcomes (internalising and externalising behaviours, placement restrictiveness).
METHODS: In this randomised control trial, parents (n=60) will be randomly assigned to PWRT or treatment as usual. Each week for 6 weeks, parents in the PWRT condition will complete two PW modules (20 min each) and attend one discussion group via Zoom (90 min). Adolescents (n=60) will not receive intervention; however, we will evaluate the feasibility of adolescent data collection for future studies. Data from parents and adolescents will be collected at baseline, post intervention (6 weeks post baseline) and 6 months post baseline to allow for a robust understanding of the longer-term effects of PWRT on treatment gain maintenance.
BACKGROUND: The study has been approved by The Ohio State University Institutional Review Board (protocol number 2022B0315). The outcomes of the study will be shared through presentations at both local and national conferences, publications in peer-reviewed journals and disseminated to the families and organisations that helped to facilitate the project.
