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..
We tested the efficacy of a brief, skills-based psychosocial programme under randomised controlled conditions following compound disasters.The SOLAR programme was associated with improvements in anxiety, depression and posttraumatic stress symptoms across time.The SOLAR programme may benefit from booster sessions especially where there are ongoing impacts of disaster.

Exposure to trauma is pervasive in societies worldwide and is associated with substantial costs to the individual and society, making it a significant global public health concern. We present evidence for trauma as a public health issue by highlighting the role of characteristics operating at multiple levels of influence - individual, relationship, community, and society - as explanatory factors in both the occurrence of trauma and its sequelae. Within the context of this multi-level framework, we highlight targets for prevention of trauma and its downstream consequences and provide examples of where public health approaches to prevention have met with success. Finally, we describe the essential role of public health policies in addressing trauma as a global public health issue, including key challenges for global mental health and next steps for developing and implementing a trauma-informed public health policy agenda. A public health framework is critical for understanding risk and protective factors for trauma and its aftermath operating at multiple levels of influence and generating opportunities for prevention.
La exposición al trauma es general en las sociedades de todo el mundo y está asociada con costos sustanciales para el individuo y la sociedad, lo que la convierte en un importante problema mundial de salud pública. Presentamos evidencia del trauma como problema de salud pública al destacar el papel de las características que operan en múltiples niveles de influencia -individuo, relación, comunidad y sociedad- como factores que explican tanto la ocurrencia del trauma como sus secuelas. En el contexto de este marco multi-nivel, destacamos objetivos para la prevención del trauma y sus consecuencias posteriores, y ofrecemos ejemplos de los casos en que los abordajes preventivos de salud pública han tenido éxito. Por último, describimos el papel esencial de las políticas de salud pública a la hora de abordar el trauma como problema de salud pública mundial, incluyendo los retos clave para la salud mental global y los próximos pasos para desarrollar e implementar una agenda de políticas de salud pública. Un marco de salud pública es fundamental para comprender los factores de riesgo y de protección para el trauma y sus secuelas, que operan en múltiples niveles de influencia y generan oportunidades de prevención.
摘要：创伤暴露在世界范围的社会中都普遍存在，且对个人和社会造成了重大的损失。这使得创伤暴露成为了一个显著的世界公共健康问题。我们强调有特色的应对（characteristics operating）在多重水平上（个人、关系、社区和社会）的影响是创伤的发生及其后果的解释因素，从而提出创伤是公共健康问题的证据。在这一多水平框架的背景下，我们强调了预防创伤的目标和随之带来的后果，并举出利用公共健康方法成功预防创伤的例子。最终，我们描述了公共卫生政策在解决作为全球公共健康问题的创伤时扮演的重要角色，全球精神健康面临的关键挑战，以及发展和实施针对创伤的公共健康政策日程的未来步骤。不论是理解创伤的危险和保护因素以及创伤后应对方式在多重水平上的影响，还是促发预防机会，公共健康框架都至关重要。.

OBJECTIVE: There is little information about continued use of point-of-use technologies after disaster relief efforts. After the 2004 tsunami, the Red Cross distributed ceramic water filters in Sri Lanka. This study determined factors associated with filter disuse and evaluate the quality of household drinking water.
METHODS: A cross-sectional survey of water sources and treatment, filter use and household characteristics was administered by in-person oral interview, and household water quality was tested. Multivariable logistic regression was used to model probability of filter non-use.
RESULTS: At the time of survey, 24% of households (107/452) did not use filters; the most common reason given was breakage (42%). The most common household water sources were taps and wells. Wells were used by 45% of filter users and 28% of non-users. Of households with taps, 75% had source water Escherichia coli in the lowest World Health Organisation risk category (<1/100 ml), vs. only 30% of households reporting wells did. Tap households were approximately four times more likely to discontinue filter use than well households.
CONCLUSIONS: After 2 years, 24% of households were non-users. The main factors were breakage and household water source; households with taps were more likely to stop use than households with wells. Tap water users also had higher-quality source water, suggesting that disuse is not necessarily negative and monitoring of water quality can aid decision-making about continued use. To promote continued use, disaster recovery filter distribution efforts must be joined with capacity building for long-term water monitoring, supply chains and local production.
