Background: In Cambodia, malaria persists with changing epidemiology and resistance to antimalarials. This study aimed to describe how malaria has evolved spatially from 2006 to 2019 in Cambodia. Methods: We undertook a secondary analysis of existing malaria data from all government healthcare facilities in Cambodia. The epidemiology of malaria was described by sex, age, seasonality, and species. Spatial clusters at the district level were identified with a Poisson model. Results: Overall, incidence decreased from 7.4 cases/1000 population in 2006 to 1.9 in 2019. The decrease has been drastic for females, from 6.7 to 0.6/1000. Adults aged 15–49 years had the highest malaria incidence among all age groups. The proportion of Plasmodium (P.) falciparum + Mixed among confirmed cases declined from 87.9% (n = 67,489) in 2006 to 16.6% (n = 5290) in 2019. Clusters of P. falciparum + Mixed and P. vivax + Mixed were detected in forested provinces along all national borders. Conclusions: There has been a noted decrease in P. falciparum cases in 2019, suggesting that an intensification plan should be maintained. A decline in P. vivax cases was also noted, although less pronounced. Interventions aimed at preventing new infections of P. vivax and relapses should be prioritized. All detected malaria cases should be captured by the national surveillance system to avoid misleading trends.

Introduction: Determinants and drivers for emergencies, such as political instability, weak health systems, climate change and forcibly displaced populations, are increasing the severity, complexity and frequency of public health emergencies. As emergencies become more complex, it is increasingly important that the required skillset of the emergency response workforce is clearly defined. To enable essential epidemiological activities to be implemented and managed during an emergency, a workforce is required with the right mix of skills, knowledge, experience and local context awareness. This study aims to provide local and international responders with an opportunity to actively contribute to the development of new thinking around emergency response roles and required competencies. In this study, we will develop recommendations using a broad range of evidence to address identified lessons and challenges so that future major emergency responses are culturally and contextually appropriate, and less reliant on long-term international deployments. Method and analysis: We will conduct a mixed-methods study using an exploratory sequential study design. The integration of four data sources, including key informant interviews, a scoping literature review, survey and semistructured interviews will allow the research questions to be examined in a flexible, semistructured way, from a range of perspectives. The study is unequally weighted, with a qualitative emphasis. We will analyse all activities as individual components, and then together in an integrated analysis. Thematic analysis will be conducted in NVivo V.11 and quantitative analysis will be conducted in Stata V.15. Ethics and dissemination: All activities have been approved by the Science and Medical Delegated Ethics Review Committee at the Australian National University (protocol numbers 2018-521, 2018-641, 2019-068). Findings will be disseminated through international and local deployment partners, peer-reviewed publication, presentation at international conferences and through social media such as Twitter and Facebook. ; AEP receives Commonwealth and ANU science merit scholarships, along with funding from the Australian National Health and Medical Research Council (NHMRC) Integrated Systems for Epidemic Response (APP1107393).

Abstract
Background
An extensive body of research exists looking at the level of psychological distress in populations affected by political conflict. Recommended response to psychological distress in humanitarian crises is still based on frameworks for interventions developed in western/European contexts including psychological first aid, counselling and group therapy. While there is growing, but limited, evidence that culturally modified interventions can lead to reduction in symptoms of psychological distress in conflict affected populations, there is a need to understand mental health help-seeking behaviour and mental health service needs from the perspective of affected communities.

Methods
This study employed a qualitative exploratory research design based on principles of grounded theory. A combination of convenience and snowball sampling was used to recruit 186 adults from the general population to 20 focus group discussions; 95 men, median age 40 years, interquartile range (IQR): 27–48 years and 91 women, median age 40 years IQR: 32–50 years. Trained Kashmiri facilitators used a semi-structured interview guide to ascertain community perceptions on mental illness, help-seeking and service needs from the perspective of communities in the Kashmir Valley. Content analysis of transcripts resulted in the identification of seven overarching themes.

Results
Common locally recognized symptoms of psychological distress were synonymous with symptoms listed in the Hopkins Symptoms Checklist (HSCL-25) and the Harvard Trauma Questionnaire (HTQ). Protracted political insecurity was highlighted as a major perceived cause of psychological distress in communities. Mental health help-seeking included traditional/spiritual healers in combination with practitioners of western medicine, with access highlighted as the main barrier. Divergent views were expressed on the effectiveness of treatment received. Participants' expressed the need for investment in mental health literacy to improve the community's capacity to recognize and support those suffering from psychological distress.

Conclusions
Our findings demonstrate the universality of symptoms of psychological distress whilst simultaneously highlighting the importance of recognizing the cultural, spiritual and contextual framework within which psychological distress is understood and manifest. Co-constructed models of community based mental health services are needed.

BACKGROUND: Improving the epidemiological response to emergencies requires an understanding of who the responders are, their role and skills, and the challenges they face during responses. In this paper, we explore the role of the epidemiologist and identify challenges they face during emergency response. METHODS: We conducted a cross-sectional survey to learn more about epidemiologists who respond to public health emergencies. The online survey included open and closed-ended questions on challenges faced while responding, the roles of epidemiology responders, self-rating of skills, and support needed and received. We used purposive sampling to identify participants and a snowballing approach thereafter. We compared data by a number of characteristics, including national or international responder on their last response prior to the survey. We analysed the data using descriptive, content, and exploratory factor analysis. RESULTS: We received 166 responses from individuals with experience in emergency response. The most frequently reported challenge was navigating the political dynamics of a response, which was more common for international responders than national. National responders experienced fewer challenges related to culture, language, and communication. Epidemiology responders reported a lack of response role clarity, limited knowledge sharing, and communication issues during emergency response. Sixty-seven percent of participants reported they needed support to do their job well; males who requested support were statistically more likely to receive it than females who asked. CONCLUSIONS: Our study identified that national responders have additional strengths, such as better understanding of the local political environment, language, and culture, which may in turn support identification of local needs and priorities. Although this research was conducted prior to the COVID-19 pandemic, the results are even more relevant now. This research builds on emerging evidence on how to strengthen public health ...

Abstract
Background
The negative psychological impact of living in a setting of protracted conflict has been well studied, however there is a recognized need to understand the role that non-conflict related factors have on mediating exposure to trauma and signs of psychological distress.

Methods
We used data from the 2015 Kashmir Mental Health Survey and conducted mediation analysis to assess the extent to which daily stressors mediated the effect of traumatic experiences on poor mental health outcomes. Outcomes of interest were probable diagnosis of anxiety, depression, or PTSD; measured using the pre-validated Hopkins Symptoms Checklist (HSCL-25) and the Harvard Trauma Questionnaire (HTQ).

Results
Total effect mediated were statistically significant but the proportions of effect mediated were found to be small in practical terms. Financial stress mediated 6.8% [95% Confidence Interval (CI) 6∙0–8∙4], 6.7% [CI 6.2–7∙7] and 3.6% [CI 3∙4–4∙0] of the effect of experiencing multiple traumaticogenic events on symptoms of anxiety, depression and PTSD, respectively. Family stress mediated 11.3% [CI 10.3–13.8], 10.3% [CI 9.5–11.9] and 6.1% [CI 5.7–6.7] of the effect of experiencing multiple traumatogenic events on symptoms of anxiety, depression and PTSD, respectively. Poor physical health mediated 10.0% [CI 9.1–12∙0], 7.2% [CI 6.6–8.2] and 4.0% [CI 3.8,4.4] of the effect of experiencing more than seven traumatic events on symptoms of anxiety, depression and PTSD, respectively.

Conclusion
Our findings highlight that not only do we need to move beyond a trauma-focussed approach to addressing psychological distress in populations affected by protracted conflict but we must also move beyond focussing on daily stressors as explanatory mediators.

BACKGROUND: Following the partition of India in 1947, the Kashmir Valley has been subject to continual political insecurity and ongoing conflict, the region remains highly militarised. We conducted a representative cross-sectional population-based survey of adults to estimate the prevalence and predictors of anxiety, depression and post-traumatic stress disorder (PTSD) in the 10 districts of the Kashmir Valley. METHODS: Between October and December 2015, we interviewed 5519 out of 5600 invited participants, ≥18 years of age, randomly sampled using a probability proportional to size cluster sampling design. We estimated the prevalence of a probable psychological disorder using the Hopkins Symptom Checklist (HSCL-25) and the Harvard Trauma Questionnaire (HTQ-16). Both screening instruments had been culturally adapted and translated. Data were weighted to account for the sampling design and multivariate logistic regression analysis was conducted to identify risk factors for developing symptoms of psychological distress. FINDINGS: The estimated prevalence of mental distress in adults in the Kashmir Valley was 45% (95% CI 42.6 to 47.0). We identified 41% (95% CI 39.2 to 43.4) of adults with probable depression, 26% (95% CI 23.8 to 27.5) with probable anxiety and 19% (95% CI 17.5 to 21.2) with probable PTSD. The three disorders were associated with the following characteristics: being female, over 55 years of age, having had no formal education, living in a rural area and being widowed/divorced or separated. A dose-response association was found between the number of traumatic events experienced or witnessed and all three mental disorders. INTERPRETATION: The implementation of mental health awareness programmes, interventions aimed at high risk groups and addressing trauma-related symptoms from all causes are needed in the Kashmir Valley.

The present study aimed to culturally adapt, translate, and validate the Hopkins Symptom Checklist-25 (HSCL-25) and the Harvard Trauma Questionnaire-Posttraumatic Stress Symptoms Checklist (HTQ-16) prior to use in a cross-sectional mental health population survey in the Kashmir Valley. Cultural adaptation and translation of the HSCL-25 and the HTQ-16 employed multiple forms of transcultural validity check. The HSCL-25 and HTQ-16 were compared against a "gold standard" structured psychiatric interview, the Mini International Neuropsychiatric Interview (MINI). Interviews were conducted with 290 respondents recruited using consecutive sampling from general medical outpatient departments in five districts of the Kashmir Valley. Receiver operating characteristics (ROC) analysis was used to estimate the cut point with optimal discriminatory power based on sensitivity and specificity. Internal reliability of the HSCL-25 was high, Cronbach's alpha (α) = .92, intraclass correlation coefficient (ICC) = 0.75, with an estimated optimal cut point of 1.50, lower than the conventional cut point of 1.75. Separation of the instruments into subscales demonstrated a difference in the estimated cut point for the anxiety subscale and the depression subscale, 1.75 and 1.57, respectively. Too few respondents were diagnosed with posttraumatic stress disorder (PTSD) during structured psychiatric interview, and therefore the HTQ-16 could not be validated despite the fact that high internal reliability was demonstrated (α = .90). This study verified the importance of culturally adapting and validating screening instruments in particular contexts. The use of the conventional cut point of 1.75 would likely have misclassified depression in our survey, leading to an underestimate of this condition.
