Piloting a scalable, post-trauma psychosocial intervention in Tuvalu: the Skills for Life Adjustment and Resilience (SOLAR) program

The mental health impact of climate change on Pacific Islanders: A systematic review focused on sea level rise and extreme weather events

ObjectiveThis systematic review investigates the impact of climate change on the mental health of Pacific Island Nations (PINs), with a focus on identifying culturally tailored interventions and appropriate research methodologies to address these impacts.MethodA systematic review of peer-reviewed literature up to May 18, 2024, was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol and the Population, Interest Area, and Context (PICo) framework. Empirical studies on the impact of climate change on mental health in PINs were evaluated by using the Quality Assessment Tool for Studies with Diverse Designs (QATSDD).ResultsSix studies from the Solomon Islands, Cook Islands, and Tuvalu were identified, indicating significant mental health impacts from sea level rise (SLR) and extreme weather events with compounding and mitigating effects across diverse groups. The Skills for Life Adjustment and Resilience (SOLAR) program was highlighted as a promising culturally adapted intervention.ConclusionClimate change significantly impacts mental health, particularly in PIN communities facing SLR and Extreme Weather Events (EWE). Culturally sensitive interventions, local knowledge, and further research are vital to mitigate these effects and support well-being.

A scoping review of psychosocial interventions delivered by non-mental health workers following disaster events

Individuals exposed to disasters are at high risk of developing mental health conditions, yet the availability of mental health practitioners is often limited. The aim of this scoping review was to examine the quality of the evidence for psychosocial interventions that can be delivered by non-mental health workers in the context of disasters. Searches were performed in PsycInfo, EMBASE, Family & Society Studies Worldwide, CINAHL, Global Health, PubMed, and SCOPUS, from inception through to November 2024, to identify studies of relevance. Only studies investigating psychosocial interventions that could be delivered by non-mental health clinicians in a non-hospital or clinic setting were included. In total, 69 primary intervention studies examining 27 universal interventions and 10 indicated interventions were identified. Studies were rated on quality and risk of bias, and GRADE was used to rank the evidence for each intervention. For universal interventions, no study had an evidence rating above "very low" to support confidence in a significant impact on clinical outcomes. For indicated interventions, Problem Management Plus (PM+) and Self-Help Plus (SH+) had an evidence rating of "high" in the postdisaster context, and Skills for Life Adjustment and Resilience (SOLAR) had a "low" evidence rating; the remaining interventions were given "very low" ratings. Despite the high number of psychosocial interventions that target postdisaster distress, very few have been tested using rigorous methodologies with large samples. Future research should include methodologies that test interventions at scale and recognize the impacts of compounding disasters.

Cultural Adaptations to the Assessment and Treatment of Trauma Experiences Among Racial and Ethnic Minority Groups: A Mixed-Methods Systematic Review and Meta-Analysis

A higher prevalence of post-traumatic stress disorder (PTSD) exists among racial and ethnic minority groups who experience trauma; however, little is known about cultural adaptations of trauma assessments and interventions, or whether those adaptations meet cultural needs. This systematic review examined the effectiveness and experiences of culturally adapted trauma assessments and interventions for adults from racial and ethnic minority groups. Empirical studies investigating culturally adapted trauma assessment and/or interventions targeting adults from racial and ethnic minority groups were searched for in MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, Web of Science, from inception to May 2022. A total of 21 articles were included, and 8 common themes of adaptations were identified: socio-cultural integrations, collaboration, psychoeducation, language, cultural matching, addressing stigma, training for providers, and practical considerations. Random effects meta-analyses on intervention effects showed that culturally adapted interventions were more effective in reducing PTSD symptoms (7 randomized controlled trials [RCTs], n = 213, Standardized Mean Difference -0.67, 95% CI [-1.06, -0.25], I2 = 39%) and in ameliorating anxiety symptoms (5 RCTs, n = 168, SMD -1.92, 95% CI [-3.18, -0.67], I2 = 89%) when compared with non-adapted interventions at immediate post-intervention. No statistical difference in effects was found on depression, nor on PTSD or anxiety sustained beyond the post-intervention time-point. Thematic synthesis on participants' experiences showed that adapted interventions had positive influences on attitudes toward mental health and engagement with services. Future research should employ large-scale trial methods to test adapted trauma interventions over longer follow-up periods as well as to explore the subjective experiences of users of adapted interventions.

Digital Mental Health Innovations in the Face of Climate Change: Navigating a Sustainable Future

Climate change poses substantial challenges to mental health, with increased frequency of extreme weather events and environmental degradation exacerbating stress, anxiety, trauma, and existential concerns. Digital innovations, particularly artificial intelligence and digital phenotyping, offer promising avenues to mitigate climate-related mental health burdens. The integration of digital tools into climate-related mental health care necessitates careful consideration of issues of access to and adoption of solutions. Future research should evaluate the effectiveness and scalability of digital interventions to address the mental health impacts of climate change through collaborative efforts involving clinicians, environmental health specialists, bioethicists, policy makers, and technology developers.

Taking a trauma and adversity perspective to climate change mental health

The European Journal of Psychotraumatology has had a long interest in advancing the science around climate change and traumatic stress. In this special issue, we include papers that responded to a special call in this area. Six major themes emerge from these papers and together they contribute to trauma and adversity model of the mental health impacts of climate change. We argue that, in addition to individual vulnerability factors, we must consider the (i) cumulative trauma burden that is associated with exposure to ongoing climate change-related impacts; (ii) impact of both direct and indirect stressors; (iii) individual and community protective factors. These factors can then guide intervention models of recovery and ongoing resilience.

Mental health and psychosocial interventions in the context of climate change: a scoping review

The evidence on the impacts of climate change on mental health and wellbeing is growing rapidly. The objective of this scoping review is to understand the extent and type of existing mental health and psychosocial interventions aimed at addressing the mental health and psychosocial impacts of climate change. A scoping review methodology was followed. MEDLINE, PsycINFO, and Web of Science databases were searched from inception to May 2022. Comprehensive gray literature search, including expert consultation, was conducted to identify interventions for which peer-reviewed academic literature may not yet be available. Data on intervention type, setting, climate stressor, mental health outcome, evaluation, and any other available details were extracted, and results were summarized narratively. Academic literature search identified 16 records and gray literature search identified a further 24 records. Altogether, 37 unique interventions or packages of interventions were identified. The interventions act at the levels of microsystem, mesosystem, exosystem, and macrosystem through diverse mechanisms. While most interventions have not been formally evaluated, promising preliminary results support interventions in low- and middle-income-country settings disproportionately affected by climate disasters. Interventions from multidisciplinary fields are emerging to reduce psychological distress and enhance mental health and wellbeing in the context of climate change. This scoping review details existing evidence on the interventions and summarizes intervention gaps and lessons learned to inform continued intervention development and scale-up interventions.

Trajectory of adjustment difficulties following disaster: 10-year longitudinal cohort study

BACKGROUND

Although much is known about psychopathology such as post-traumatic stress disorder (PTSD) and depression following bushfire (also known as wildfire), little is known about prevalence, trajectory and impacts for those experiencing general adjustment difficulties following exposure to these now-common events.

AIMS

This was an exploratory analysis of a large cohort study that examined the prevalence, trajectory and risk factors of probable adjustment disorder over a 10-year period following bushfire exposure.

METHOD

The Beyond Bushfires study assessed individuals exposed to a large and deadly bushfire across three time points spanning 10 years. Self-report survey data from participants from areas with moderate and high levels of fire-affectedness were analysed: n = 802 participants at Wave 1 (3-4 years post-fires), n = 596 at Wave 2 (5 years post-fires) and n = 436 at Wave 3 (10 years post-fires). Surveys indexed fire-related experiences and post-fire stressors, and comprised the six-item Kessler Psychological Distress Scale (probable adjustment disorder index), four-item Posttraumatic Stress Disorder Checklist (probable fire-related PTSD) and nine-item Patient Health Questionnaire (probable major depressive episode).

RESULTS

Prevalence of probable adjustment disorder was 16% (Wave 1), 15% (Wave 2) and 19% (Wave 3). Probable adjustment disorder at 3-4 years post-fires predicted a five-fold increase in risk for escalating to severe psychiatric disorder (i.e. probable fire-related PTSD/major depressive episode) at 10 years post-fires, and was associated with post-fire income and relationship stressors.

CONCLUSIONS

Adjustment difficulties are prevalent post-disaster, many of which are maintained and exacerbated over time, resulting in increased risk for later disorder and adaptation difficulties. Psychosocial interventions supporting survivors with adjustment difficulties may prevent progression to more severe disorder.

Improving mental health following multiple disasters in Australia: a randomized controlled trial of the Skills for Life Adjustment and Resilience (SOLAR) programme

Background: The mental health impacts of climate change-related disasters are significant. However, access to mental health services is often limited by the availability of trained clinicians. Although building local community capability for the mental health response is often prioritised in policy settings, the lack of evidence-based programs is problematic. The aim of this study was to test the efficacy of the Skills for Life Adjustment and Resilience programme (SOLAR) delivered by trained local community members following compound disasters (drought, wildfires, pandemic-related lockdowns) in Australia.Method: Thirty-six community members were trained to deliver the SOLAR programme, a skills-based, trauma informed, psychosocial programme. Sixty-six people with anxiety, depression and/or posttraumatic stress symptoms, and impairment were randomised into the SOLAR programme or a Self-Help condition. They were assessed pre, post and two months following the interventions. The SOLAR programme was delivered across five 1-hourly sessions (either face to face or virtually). Those in the Self-Help condition received weekly emails with self-help information including links to online educational videos.Results: Multigroup analyses indicated that participants in the SOLAR condition experienced significantly lower levels of anxiety and depression, and PTSD symptom severity between pre - and post-intervention (T1 to T2), relative to the Self-Help condition, while controlling for scores at intake. These differences were not statistically different at follow-up. The SOLAR programme was associated with large effect size improvements in posttraumatic stress symptoms over time.Conclusion: The SOLAR programme was effective in improving anxiety, depression and posttraumatic stress symptoms over time. However, by follow-up the size of the effect was similar to an active self-help condition. Given the ongoing stressors in the community associated with compounding disasters it may be that booster sessions would have been useful to sustain programme impact.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12621000283875..

Promoting Recovery from Disasters, Pandemics, and Trauma: A Systematic Review of Brief Psychological Interventions to Reduce Distress in Adults, Children, and Adolescents

A substantial number of survivors of disasters, pandemics, and other severe stressors develop persistent distress that impairs mental health and well-being. However, only a few brief psychological interventions target distress or subclinical symptoms. This systematic review aimed to identify and describe brief psychological interventions to reduce distress or subclinical symptoms in survivors of disasters, pandemics, and other severe stressors. Based on a systematic literature search (MEDLINE, PsycINFO, PSYNDEX, PTSDpubs, and Web of Science), we reviewed published studies and study protocols on self-help, psychosocial support, or brief psychotherapeutic interventions to reduce distress and/or subclinical symptoms following natural hazards and man-made disasters, pandemics, or other traumatic events. We included 27 published studies or study protocols (n = 15 RCTs, n = 3 controlled pre-post studies, and n = 9 uncontrolled pre-post studies) describing 22 interventions. We found evidence for reducing psychological distress and/or subclinical symptoms in 9 out of 15 RCTs, 2 out of 3 controlled pre-post studies, and 9 out of 9 uncontrolled pre-post studies. One RCT provided evidence of increasing well-being. Innovative brief interventions have been developed to reduce distress and/or subclinical symptoms that have an emerging evidence base.

Design, development and randomised controlled trial protocol of a smartphone-delivered version of 'SOLAR' for emergency service workers to manage stress and trauma

IntroductionEmergency service workers are routinely exposed to stress and trauma, and there is a need to address mental health symptoms early to prevent chronic impairment and/or psychiatric disorder. Digital health innovations mean that face-to-face psychosocial interventions can now be delivered remotely, which is particularly appealing to populations who have strong preferences for digital delivery, such as emergency service workers. This two phase study aims to first adapt the Skills fOr Life Adjustment and Resilience (SOLAR) programme into a smartphone application ('app'), and then evaluate the effectiveness of this new app.

METHODS AND ANALYSES

First, focus groups and codesign activities with mental health professionals and emergency service workers will be conducted to develop and test the prototype smartphone version of SOLAR (ie, SOLAR-m). Second, a multicentre randomised controlled trial will investigate the effectiveness of the new app, compared with an active control app, in reducing symptoms of anxiety and depression (primary outcome), as well as other indicators of mental health and work performance. Firefighters from one of the largest urban fire and rescue services in Australia who are currently experiencing distress will be invited to participate. After screening and baseline assessment, 240 will be randomised to receive either SOLAR-m or the control app for 5 weeks, with measurements pre, post and 3-month follow-up. Analyses will be conducted within an intention-to-treat framework using mixed modelling.

ETHICS AND DISSEMINATION

The current trial has received ethics approval from the University of Melbourne Human Research Ethics Committee (2021-20632-18826-5). Study results will be disseminated through peer-reviewed journals and conferences, with a focus on how to expand the new app to other trauma-affected populations if proven effective.

Regional Research-Practice-Policy Partnerships in Response to Climate-Related Disparities: Promoting Health Equity in the Pacific

Although climate change poses a threat to health and well-being globally, a regional approach to addressing climate-related health equity may be more suitable, appropriate, and appealing to under-resourced communities and countries. In support of this argument, this commentary describes an approach by a network of researchers, practitioners, and policymakers dedicated to promoting climate-related health equity in Small Island Developing States and low- and middle-income countries in the Pacific. We identify three primary sets of needs related to developing a regional capacity to address physical and mental health disparities through research, training, and assistance in policy and practice implementation: (1) limited healthcare facilities and qualified medical and mental health providers; (2) addressing the social impacts related to the cooccurrence of natural hazards, disease outbreaks, and complex emergencies; and (3) building the response capacity and resilience to climate-related extreme weather events and natural hazards.
