How much do adverse childhood experiences contribute to adolescent anxiety and depression symptoms? Evidence from the longitudinal study of Australian children.

This study aims to: (i) examine the association between adverse childhood experiences (ACEs) and elevated anxiety and depressive symptoms in adolescents; and (ii) estimate the burden of anxiety and depressive symptoms attributable to ACEs.Data were analyzed from 3089 children followed between Waves 1 (age 4-5 years) and 7 (16-17 years) of the Longitudinal Study of Australian Children. Logistic regression was used to estimate the associations between ACEs and child-reported elevated anxiety and depressive symptoms at age 16-17. Anxiety and depressive symptoms were measured using the Children's Anxiety Scale and Short Mood and Feelings Questionnaire, respectively. The punaf command available in STATA 14 was used to calculate the population attributable fraction (PAF).Before the age of 18 years, 68.8% of the children had experienced two or more ACEs. In the analysis adjusted for confounding factors, including co-occurring ACEs, both history and current exposure to bullying victimisation and parental psychological distress were associated with a statistically significant increased likelihood of elevated anxiety and depressive symptoms at age 16-17. Overall, 47% of anxiety symptoms (95% CI for PAF: 35-56) and 21% of depressive symptoms (95% CI: 12-29) were attributable to a history of bullying victimisation. Similarly, 17% (95% CI: 11-25%) of anxiety and 15% (95% CI: 4-25%) of depressive symptoms at age 16-17 years were attributable to parental psychological distress experienced between the ages of 4-15 years.The findings demonstrate that intervention to reduce ACEs, especially parental psychological distress and bullying victimisation, may reduce the substantial burden of mental disorders in the population.

Redevelopment of mental health first aid guidelines for substance use problems: a Delphi study.

BACKGROUND: Substance use problems have a major impact on the physical and mental health of individuals, families and communities. Early intervention may have a positive effect on recovery and treatment outcomes for those with substance use problems, reducing related risk and harm. Separate mental health first aid guidelines on how a member of the public could assist someone experiencing or developing alcohol use and drug use problems in high income Western countries were developed using Delphi expert consensus in 2009 and 2011, respectively. This study aimed to synthesise and update these two original guidelines to reflect current evidence and best practice. METHODS: The Delphi expert consensus method was used to determine the inclusion of statements in the redeveloped guidelines. A questionnaire was developed using previously endorsed helping statements from the original guidelines on alcohol and drug use problems, as well as relevant content identified in systematic searches of academic and grey literature. Three panels of experts (people with lived experience, support people and professionals) rated statements over three consecutive online survey rounds to determine the importance of their inclusion in the guidelines. Statements endorsed by at least 80% of each panel were included. RESULTS: 103 panellists completed all three survey rounds. They rated 469 statements and endorsed 300 of these for inclusion in the redeveloped guidelines. CONCLUSIONS: This study has developed a broader and more comprehensive set of guidelines for how to support a person experiencing or developing a substance use problem. The redeveloped guidelines provide more detail on knowledge about and recognition of substance use problems, approaching and assisting people who want to change or are not ready to change, harm reduction, community-based supports and professional help, but have less on physical first aid actions. Mental Health First Aid International will use these guidelines in future updates of their training courses.

The impact of antidepressants and human development measures on the prevalence of sadness, worry and unhappiness: cross-national comparison.

Depression is a major public health concern. Depressed individuals have received increasing treatment with antidepressants in Western countries. In this study, we examine the relationship among individual symptoms (sadness, worry and unhappiness), human development factors and antidepressant use in 29 OECD countries. We report that increased antidepressant prescribing is not associated with decreased prevalence of sadness, worry or unhappiness. However, income, education and life expectancy (measured using the Human Development Index) are associated with lower prevalence of all these symptoms. This suggests that increasing spending on depression treatment may not be as effective as general public health interventions at reducing depression in communities.

Adolescent peer support for mental health problems: evaluation of the validity and reliability of the Mental Health Support Scale for Adolescents.

BACKGROUND: The Mental Health Support Scale for Adolescents (MHSSA) is a criterion-referenced measure of adolescents' supportive intentions towards peers with mental health problems, which was developed for use in evaluations of adolescent mental health interventions, such as the teen Mental Health First Aid (tMHFA) program. The present study aimed to examine the validity and reliability of the MHSSA. METHODS: A sample of 3092 school students (Mean ± SD: 15.9 ± 0.4 years old) and 65 tMHFA Instructors (the adult group with known expertise in tMHFA) completed the 12 items of the MHSSA. A sub-sample of 1201 students repeated the scale after a 3-4-week interval. Item concordance rates with the tMHFA Action Plan across helpful and harmful intentions scales were calculated. Scale reliabilities were assessed using agreement coefficients from a single test administration and test-retest reliability measured by intraclass correlation coefficients. The mean differences of MHSSA scores of students and Instructors were compared using independent samples t-tests, while convergent validity was tested via correlations of the scale with validated measures of confidence in providing help, social distance and personal stigma. RESULTS: The average score of Instructors was significantly higher than that of students. The scale was positively associated with confidence in providing help, whilst negatively associated with social distance and dimensions of personal stigma. All scales of MHSSA had high agreement coefficients (all > 0.80) and fair to good test-retest reliability over 3-4 weeks. CONCLUSIONS: The MHSSA shows evidence of validity and reliability for use among adolescents for evaluating the quality of intentions to help peers with mental health problems.

Evaluation of the Conversations about Non-Suicidal Self-Injury Mental Health First Aid Course: Effects on Knowledge, Stigmatising Attitudes, Confidence and Helping Behaviour.

BACKGROUND: Non-suicidal self-injury (NSSI) is a common mental health problem, with a 19% lifetime prevalence in Australian adolescents and 12% in adults. Though rates of professional help-seeking for NSSI are low, disclosure to family and friends is more common, providing opportunities for them to encourage professional support. Mental Health First Aid® Australia's Conversations about Non-Suicidal Self-Injury course provides evidence-based training for the general public to support a person engaging in NSSI. METHODS: This uncontrolled trial evaluated the effects of the Conversations about Non-Suicidal Self-Injury course on participants' knowledge, confidence, stigmatising attitudes, and intended and actual helping behaviours. Surveys were administered pre- and post-course, and at a six-month follow-up. A linear mixed-model analysis determined mean change over time, and effect sizes were estimated using Cohen's d. Course satisfaction was assessed using descriptive statistics and summative content analysis of qualitative data. RESULTS: The pre-course survey was completed by 147 Australian participants (77.5% female, mean age 45.8 years), 137 (93.2%) at post-course and 72 (49%) at follow-up. Knowledge, confidence, quality of intended helping behaviours, and quality of actual helping behaviours increased significantly at both time points. Social distance decreased significantly at all time points and stigma decreased significantly at post-course. The course was perceived to be highly acceptable by participants. CONCLUSIONS: There is initial evidence that the Conversations about Non-Suicidal Self-Injury course is effective and acceptable for members of the public who may support a person engaging in NSSI.

Establishing conversion of the 16-item Informant Questionnaire on Cognitive Decline in the Elderly scores into interval-level data across multiple samples using Rasch methodology.

BACKGROUND: The 16-item Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-16) is a well-validated and widely-used measure of cognitive changes (CCs) among older adults. This study aimed to use Rasch methodology to establish psychometric properties of the IQCODE-16 and validate the existing ordinal-to-interval transformation algorithms across multiple large samples. METHODS: A Partial Credit Rasch model was employed to examine psychometric properties of the IQCODE-16 using data (n = 918) from two longitudinal studies of participants aged 57-99 years: the Older Australian Twins Study (n = 450) and the Canberra Longitudinal Study (n = 468), and reusing the Sydney Memory and Ageing Study (MAS) sample (n = 400). RESULTS: Initial analyses indicated good reliability for the IQCODE-16 (Person Separation Index range: 0.82-0.90). However, local dependency was identified between items, with several items showing misfit to the model. Replicating the existing Rasch solution could not reproduce the best Rasch model fit for all samples. Combining locally dependent items into three testlets resolved all misfit and local dependency issues and resulted in the best Rasch model fit for all samples with evidence of unidimensionality, strong reliability, and invariance across person factors. Accordingly, new ordinal-to-interval transformation algorithms were produced to convert the IQCODE-16 ordinal scores into interval data to improve the accuracy of its scores. CONCLUSIONS: The findings of this study support the reliability and validity of the IQCODE-16 in measuring CCs among older adults. New ordinal-to-interval conversion tables generated using samples from multiple independent datasets are more generalizable and can be used to enhance the precision of the IQCODE-16 without changing its original format. An easy-to-use converter has been made available for clinical and research use.

Mental Health Literacy for Supporting Children: A Systematic Review of Teacher and Parent/Carer Knowledge and Recognition of Mental Health Problems in Childhood.

The level of mental health literacy (MHL) in adults who work with or care for children is likely to influence the timeliness and adequacy of support that children receive for mental health problems. The aim of this study was to systematically review the literature on mental health literacy for supporting children (MHLSC, recognition/knowledge) among parents and teachers of school aged children (5 to 12 years old). A systematic search was conducted for quantitative studies published between 2000 and June 2021 using three databases (MEDLINE, PsycINFO and ERIC) and relevant citations reviewed in Scopus. To be included, studies needed to measure at least either 'mental health knowledge' or 'recognition'. Synthesis proceeded according to study design, adult population, child MHP, then MHL outcome. Study quality was assessed using AXIS. 3322 documents were screened, 39 studies met inclusion criteria. 49% of studies examined teachers' knowledge or recognition of ADHD; only five studies reported on parent samples. Synthesis found a nascent field that was disparate in definitions, methods and measures. Little research focussed on knowledge and recognition for internalizing problems, or on parents. Methods used for measuring knowledge/recognition (vignette vs screening) were associated with different outcomes and the quality of studies was most often low to moderate. Adults appear to have good recognition of childhood ADHD but their knowledge of internalizing disorders is less clear. Further research is required to develop standard definitions and validated measures so gaps in MHLSC can be better identified across populations who have a role in supporting children with their mental health.

Development of the Mental Health Support Scale: A New Measure of Mental Health First Aid Behaviors.

Mental health first aid (MHFA) courses teach community members the knowledge and skills needed to recognize and respond to mental health problems until professional help is received or the crisis resolves. This study aimed to develop a reliable and valid measure of MHFA behaviors. A pool of actions that were recommended and not recommended were selected from MHFA guidelines and developed into two scales measuring either intended or provided support. Items were tested with a sample of 697 adults. Item response theory guided the selection of final items. The Mental Health Support Scale (MHSS) Intended version has 23 items across two subscales and the MHSS-Provided has 12 items across two subscales. These scales demonstrated convergent validity, discrimination between respondents with and without MHFA expertise, and acceptable measurement precision across a range of skill levels. Overall, findings suggest that the MHSS is a valid and useful measure of MHFA behaviors.

Mental Health First Aid Training with the Nepalese Community in Australia: An Evaluation of Effects on Knowledge, Confidence, Intentions, Willingness to have Contact and Stigmatizing Attitudes.

The aim of this study was to evaluate the effectiveness of Mental Health First Aid (MHFA) training amongst the Nepalese community in Australia by exploring the impact on knowledge about mental health first aid, confidence and intentions to help, willingness to have contact and stigmatizing attitudes towards people with mental illness. We hypothesized that since MHFA has been extensively evaluated with other communities and has been found to be effective, it would therefore be effective with this community as well. MHFA training was conducted by an accredited Nepalese-Australian MHFA Instructor with 162 participants from the Nepalese community in four states of Australia. Participants completed an evaluation questionnaire prior to the training (pre-test) and at the end of the training (post-test). The evaluation questionnaire assessed participants? knowledge about what was taught in the course, ability to recognize depression as described in a vignette, confidence in providing help, intentions to provide help, and willingness to have contact and stigmatizing attitudes towards people with mental illness. There were large improvements from pre-test to post-test in knowledge, confidence and intentions to help, medium improvements in willingness to have contact, small-to-medium improvements in stigmatizing attitudes and small improvements in recognition of depression. Participants gave high ratings of the course and the instructor. MHFA training produced improvements in knowledge, confidence, intentions, willingness to have contact and stigmatizing attitudes. The training was also well received. Further research is needed to assess persistence of these effects following the course and any changes in mental health first aid provided to the community.

teen Mental Health First Aid: 12-month outcomes from a cluster crossover randomized controlled trial evaluation of a universal program to help adolescents better support peers with a mental health problem.

BACKGROUND: teen Mental Health First Aid (tMHFA) is a universal mental health literacy, stigma reduction, help-seeking, and suicide prevention program designed for adolescents in Years 10-12 of secondary school (16-18 years). tMHFA is delivered by trained instructors, in a regular classroom setting, to increase the knowledge, attitudes and behaviours that adolescents' require to better support peers with mental health problems or mental health crises. METHODS: To explore the efficacy of tMHFA, a cluster crossover randomised controlled trial was conducted with Year 10 students in four schools in Victoria, Australia, using physical first aid training as the control intervention. Of the 1942 eligible students, 1,624 completed baseline and 894 completed follow-up surveys. Online surveys, administered one week before training and again 12-months later, included vignettes depicting peers John (depression and suicide risk) and Jeanie (social anxiety/phobia), measures of mental health first aid (quality of first aid intentions, confidence, first aid behaviours provided, and first aid behaviours received), mental health literacy (beliefs about adult help, help-seeking intentions), and stigma (social distance, weak-not-sick, dangerous/unpredictable, and would not tell anyone). RESULTS: The primary outcome-quality of first aid intentions towards the John vignette-showed statistically significant group x time interactions, with tMHFA students reporting more helpful and less unhelpful first aid intentions, than PFA students did over time. Confidence in providing first aid also showed significant interactions. First aid behaviours-both those provided to a peer with a mental health problem and those received from a peer-showed null results. Ratings of both beliefs about adult help and help-seeking intentions were found to be significantly improved among tMHFA students at follow-up. A group x time interaction was found on one stigma scale (would not tell anyone). CONCLUSIONS: This trial showed that, one year after training, tMHFA improves first aid intentions towards peers with depression and suicide risk, confidence in helping peers with mental health problems, willingness to tell someone and seek help from an adult or health professional if experiencing a mental health problem. TRIAL REGISTRATION: This research was registered with Australia New Zealand Clinical Trials Registry: ACTRN12614000061639 .

Redevelopment of mental health first aid guidelines for supporting someone experiencing a panic attack: a Delphi study.

BACKGROUND: Panic attacks and panic disorder can have a major impact on the mental health and wellbeing of those who experience them. People with recurrent panic attacks have increased odds of developing a mental disorder and of worsening the course of existing mental disorders. Early intervention efforts at the time that a panic attack occurs might reduce or prevent some of these associated negative outcomes. Expert consensus guidelines for high income Western countries on how to provide mental health first aid for panic attacks were published in 2009. The present study aims to redevelop these guidelines to ensure content reflects current evidence and best practice. METHODS: The Delphi consensus method was used to determine which helping strategies should be included in the redeveloped guidelines. A survey with items on how to assist someone who is having a panic attack was developed using the 2009 guidelines and a systematic search of grey and academic literature. Panellists with lived experience and professional experience rated these items to determine which helping statements should be included in the guidelines. RESULTS: Thirty panellists completed all three surveys. Panellists rated 158 statements, with 83 statements meeting the criteria for inclusion in the redeveloped guidelines. The endorsed statements covered: what the first aider should know about panic attacks, what they should do if they think someone is having a panic attack, what they should do if they are uncertain whether the person is having a panic attack, what they should say and do if they know the person is having a panic attack and what they should do when the panic attack has ended. CONCLUSION: This study has resulted in a more comprehensive set of guidelines than the original version, with the endorsement of 83 helping actions, compared to 27 previously. The redeveloped guidelines provide greater detail on recognising the signs of a panic attack, providing initial assistance, communicating with someone experiencing a panic attack and supporting them to seek appropriate professional help if it is needed. The guidelines will be used in future updates of Mental Health First Aid training courses.

Evaluation of the Conversations About Gambling Mental Health First Aid course: effects on knowledge, stigmatising attitudes, confidence and helping behaviour.

BACKGROUND: The effects of problem gambling are wide-ranging, affecting many aspects of health and negatively impacting the person who gambles, their family and friends, and their community. People experiencing problem gambling have low rates of help-seeking and perceive many barriers to treatment, although evidence suggests that encouragement and support from friends and family can increase rates of help-seeking. Mental Health First Aid Australia's Conversations About Gambling course aims to teach members of the public evidence-based strategies for recognising and responding to signs of problem gambling in a person they know. METHODS: This research evaluated the effects of the Conversations About Gambling course on participants' knowledge, confidence, stigmatising attitudes, intended helping behaviour and actual helping behaviour towards a person experiencing problem gambling. Participants from Australia completed surveys before the course, immediately after the course and six months later. Changes over time (pre-course to post-course, and pre-course to 6-month follow-up) were assessed with linear mixed models. Descriptive statistics and content analyses of open-ended questions pertaining to participants' satisfaction with the course were also produced. RESULTS: Between 2018 and 2020, 166 participants were recruited into this study. At 6-month follow-up 87 participants (52.4%) provided data. Participants' knowledge about gambling and gambling problems, confidence, desire for social distance and intentions to help a person experiencing problem gambling significantly improved from pre-course to post-course, and from pre-course to 6-month follow-up. The quality of some actions taken to support a person they knew who was experiencing problem gambling also improved from pre-course to 6-month follow-up, in line with the teachings of the course. Participants perceived the course to be highly acceptable. CONCLUSIONS: The results of this initial evaluation of Mental Health First Aid Australia's Conversations About Gambling course suggest that it is an effective and acceptable educational intervention for those who wish to support a person experiencing problem gambling.

The Role of Parent Engagement in a Web-Based Preventive Parenting Intervention for Child Mental Health in Predicting Parenting, Parent and Child Outcomes.

Although parents' engagement in parenting programmes has frequently been posited to influence the efficacy and dissemination of these programmes, its relationship with intervention outcomes in parenting programmes is understudied. This study examined the predictive value of parental engagement on preventive parenting outcomes in a tailored online parenting programme aimed at enhancing parental protective factors and reducing risk factors for child depression and anxiety disorders. The present study also explored the associations between parental engagement and other parent, child and family outcomes. Data were collected from a community sample of 177 parents who received a tailored online parenting programme ('Parenting Resilient Kids'; PaRK) and their children as part of a randomised controlled trial. Participants completed measures on parenting, child anxiety and depressive symptoms, health-related quality of life and family functioning on three occasions. Multiple regressions showed that parental engagement explained additional variance in preventive parenting (most proximal outcomes) at post-intervention and 12-month follow-up. Indicators of higher levels of parental engagement, operationalised by greater proportions of recommended programme modules and intended goals completed, uniquely predicted higher levels of preventing parenting. Higher levels of parental engagement also predicted higher levels of parental acceptance and parental psychosocial health-related quality of life, lower levels of parental psychological control and lower levels of impairments in child health-related quality of life. However, parental engagement did not explain additional variance in parent or child reported anxiety or depressive symptoms. This study provides support for the role of parental engagement in facilitating parenting changes in parenting-focused interventions.

Pilot trial of a media intervention with journalism students on news reporting of mental illness in the context of violence and crime.

ISSUE ADDRESSED: News reports linking mental illness to violent crime are among the most stigmatising portrayals. These portrayals can perpetuate stereotypes of dangerousness, negatively influencing public attitudes and having a harmful impact on people with lived experience of mental illness. With the aim of improving the quality of news portrayals and mitigating harm, best-practice guidelines for media reporting on mental illness, violence and crime have been developed. To increase understanding of the guidelines' content, a 1-hour workshop based on the main principles was developed for journalism students. METHODS: In this study, the workshop was piloted with a pre and 3-week follow-up evaluation with a cohort of journalism students (n = 29). RESULTS: Three weeks after the workshop, there were significant improvements in attitudes towards severe mental illness, knowledge of best-practice reporting, intentions and confidence to report consistently with the best-practice guidelines and performance on an editing task designed to assess adherence to the guidelines. Belief in dangerousness/unpredictability reduced markedly, demonstrating that the workshop effectively addressed misinformation about people with severe mental illness being a risk to the public. CONCLUSIONS: This pilot trial provides promising initial results and provides a basis for wider implementation and evaluation of media training on this topic. SO WHAT: Improved understanding of best-practice media guidelines, as generated through this workshop, has potential to reduce stigmatising news reporting on people with mental illness, and consequently reduce public stigma.

Discrimination experienced by Aboriginal and Torres Strait Islander males in Australia: Associations with suicidal thoughts and depressive symptoms.

INTRODUCTION: Globally, Indigenous populations have higher rates of suicidal behavior and psychological distress compared to non-Indigenous populations. Indigenous populations also report high rates of exposure to discrimination, which could potentially contribute to poor mental health outcomes. The objectives of this paper were to estimate the prevalence of discrimination among Aboriginal and Torres Strait Islander males in Australia and to examine the role of discrimination in the association between Aboriginal and Torres Strait Islander status and suicidal thoughts and depressive symptoms. METHODS: We used cross-sectional data on 13,697 males aged 18-55 years from the Australian Longitudinal Study on Male Health. We undertook a Poisson regression with robust standard error analyses to examine Aboriginal and Torres Strait Islander status and self-perceived exposure to discrimination in the past 2 years as correlates of recent suicidal ideation. We used zero-inflated negative binomial regression to assess Aboriginal and Torres Strait Islander status and self-perceived exposure to discrimination as correlates of recent depressive symptoms. RESULTS: Aboriginal and Torres Strait Islander males have a twofold higher prevalence of self-perceived discrimination (39.2% vs 19.3%, p < 0.001), suicidal ideation (21.8% vs 9.4%, p < 0.001) and moderate or worse depressive symptoms (24.0% vs 12.2%, p < 0.001) as compared to their non-Indigenous counterparts. After adjusting for sociodemographics and substance use, Aboriginal and Torres Strait Islander status was significantly associated with suicidal thoughts (odds ratio = 1.49, p = 0.019) and depressive symptoms (prevalence rate ratio = 1.19, p = 0.018). About 15.3% and 28.7% of the association between Aboriginal and Torres Strait Islander status and suicidal thoughts and depressive symptoms, respectively, was explained by discrimination. CONCLUSION: Our analyses add to evidence that discrimination is a contributor to mental health disparities between Aboriginal and Torres Strait Islander and non-Indigenous populations in Australia. Reducing discrimination ought to be considered as part of strategies to improve the social and emotional well-being of Aboriginal and Torres Strait Islander people.

The association between adverse childhood experiences and common mental disorders and suicidality: an umbrella review of systematic reviews and meta-analyses.

Adverse childhood experiences (ACEs) are related to increased risk of common mental disorders. This umbrella review of systematic reviews and meta-analyses aimed to identify the key ACEs that are consistently associated with increased risk of mental disorders and suicidality. We searched PsycINFO, PubMed, and Google Scholar for systematic reviews and meta-analyses on the association between ACEs and common mental disorders or suicidality published from January 1, 2009 until July 11, 2019. The methodological quality of included reviews was evaluated using the AMSTAR2 checklist. The effect sizes reported in each meta-analysis were combined using a random-effects model. Meta-regressions were conducted to investigate whether associations vary by gender or age of exposure to ACEs. This review is registered with PROSPERO (CRD42019146431). We included 68 reviews with moderate (55%), low (28%) or critically low (17%) methodological quality. The median number of included studies in these reviews was 14 (2-277). Across identified reviews, 24 ACEs were associated with increased risk of common mental disorders or suicidality. ACEs were associated with a two-fold higher odds of anxiety disorders (pooled odds ratios (ORs): 1.94; 95% CI 1.82, 2.22), internalizing disorders (OR 1.76; 1.59, 1.87), depression (OR 2.01; 1.86, 2.32) and suicidality (OR 2.33; 2.11, 2.56). These associations did not significantly (P > 0.05) vary by gender or the age of exposure. ACEs are consistently associated with increased risk of common mental disorders and suicidality. Well-designed cohort studies to track the impact of ACEs, and trials of interventions to prevent them or reduce their impact should be global research priorities.

A Delphi study to identify intervention priorities to prevent the occurrence and reduce the impact of adverse childhood experiences.

OBJECTIVE: There is a lack of a systematic, coordinated approach to reducing the occurrence and impact of adverse childhood experiences. Hence, identifying feasible intervention priorities in this field will help inform policy and reformation of ongoing service delivery. The objective of this study was to identify expert consensus-driven priority interventions for reducing the occurrence and impact of adverse childhood experiences in children under 8 years of age in the Australian context. METHODS: A three-round online Delphi survey was conducted to establish consensus on 34 interventions for adverse childhood experiences identified through a literature search. Six were general categories of interventions, 6 were broad intervention programmes and 22 were specific interventions. Participants were 17 health practitioners, 15 researchers, 9 policy experts, 7 educators and 3 consumer advocates with expertise in adverse childhood experiences or child mental health. Consensus was defined as an intervention being rated as 'very high priority' or 'high priority' according to its importance and feasibility by ⩾75% of all experts. RESULTS: Seven of the 34 interventions were endorsed as priority interventions for adverse childhood experiences. These included four general categories of intervention: community-wide interventions, parenting programmes, home-visiting programmes and psychological interventions. Two broad intervention programmes were also endorsed: school-based anti-bullying interventions and psychological therapies for children exposed to trauma. Positive Parenting Program was the only specific intervention that achieved consensus. CONCLUSION: This is the first study to identify stakeholder perspectives on intervention priorities to prevent the occurrence and impact of adverse childhood experiences. Prioritisation of effective, feasible and implementable intervention programmes is an important step towards better integration and coordination of ongoing service delivery to effectively prevent and respond to adverse childhood experiences.
