Objective:Although disasters are a major cause of mental health problems and typically affect large numbers of people and communities, little is known about how social structures affect mental health ...after a disaster. The authors assessed the extent to which mental health outcomes after disaster are associated with social network structures.Method:In a community-based cohort study of survivors of a major bushfire disaster, participants (N=558) were assessed for probable posttraumatic stress disorder (PTSD) and probable depression. Social networks were assessed by asking participants to nominate people with whom they felt personally close. These nominations were used to construct a social network map that showed each participant’s ties to other participants they nominated and also to other participants who nominated them. This map was then analyzed for prevailing patterns of mental health outcomes.Results:Depression risk was higher for participants who reported fewer social connections, were connected to other depressed people, or were connected to people who had left their community. PTSD risk was higher if fewer people reported being connected with the participant, if those who felt close to the participant had higher levels of property loss, or if the participant was linked to others who were themselves not interconnected. Interestingly, being connected to other people who in turn were reciprocally close to each other was associated with a lower risk of PTSD.Conclusions:These findings provide the first evidence of disorder-specific patterns in relation to one’s social connections after disaster. Depression appears to co-occur in linked individuals, whereas PTSD risk is increased with social fragmentation. These patterns underscore the need to adopt a sociocentric perspective of postdisaster mental health in order to better understand the potential for societal interventions in the wake of disaster.
Objective:
We aimed to map the prevalence and predictors of psychological outcomes in affected communities 3–4 years after the Black Saturday bushfires in the state of Victoria, Australia.
Methods:
...Baseline assessment of a longitudinal cohort study in high-, medium-, and low-affected communities in Victoria. Participants included 1017 residents of high-, medium-, and low-affected fire communities. Participants were surveyed by means of a telephone and web-based interview between December 2011 and January 2013. The survey included measures of fire-related post-traumatic stress disorder (PTSD) and general PTSD from other traumatic events, major depressive episode, alcohol use, and general psychological distress.
Results:
The majority of respondents in the high- (77.3%), medium- (81.3%), and low-affected (84.9%) communities reported no psychological distress on the K6 screening scale. More participants in the high-affected communities (15.6%) reported probable PTSD linked to the bushfires than medium- (7.2%) and low-affected (1.0%) communities (odds ratio (OR): 4.57, 95% confidence interval (CI): 2.61–8.00, p = 0.000). Similar patterns were observed for depression (12.9%, 8.8%, 6.3%, respectively) (OR: 1.83, 95% CI: 1.17–2.85, p = 0.008) and severe psychological distress (9.8%, 5.0%, 4.9%, respectively) (OR: 2.08, 95% CI: 1.23–3.55, p = 0.007). All communities reported elevated rates of heavy drinking (24.7%, 18.7%, 19.6%, respectively); however, these were higher in the high-affected communities (OR: 1.39, 95% CI: 1.01–1.89, p = 0.04). Severe psychological distress was predicted by fear for one’s life in the bushfires, death of someone close to them in the bushfires, and subsequent stressors. One-third of those with severe psychological distress did not receive mental health assistance in the previous month.
Conclusions:
Several years following the Black Saturday bushfires the majority of affected people demonstrated resilience without indications of psychological distress. A significant minority of people in the high-affected communities reported persistent PTSD, depression, and psychological distress, indicating the need for promotion of the use of health and complementary services, community-based initiatives, and family and other informal supports, to target these persistent problems.
Social disruption caused by natural disasters often interrupts educational opportunities for children. However, little is known about children's learning in the following years. This study examined ...change in academic scores for children variably exposed to a major bushfire in Australia. Comparisons were made between children attending high, medium, and low disaster-affected primary schools 2-4 years after the disaster (n = 24,642; 9-12 years). The results showed that in reading and numeracy expected gains from Year 3 to Year 5 scores were reduced in schools with higher levels of bushfire impact. The findings highlight the extended period of academic impact and identify important opportunities for intervention in the education system to enable children to achieve their academic potential.

Although much research has focused on the influence of second language (L2) proficiency on L2 use and on outcomes of intercultural adaptation, these two strands have remained largely separate. This ...study examines the impact of willingness to communicate in the L2 (L2 WTC) on the daily hassles and stress of international students, with the aim of demonstrating a conceptual overlap of the L2 WTC model with theories of stress and cross-cultural adaptation that focus on a transactional person-environment fit. Participants included 104 Chinese-speaking students attending a British university. Structural equation modeling supported a model in which L2 WTC played a significant role in the experience of daily hassles related to communication difficulties, social isolation, and time and financial constraints. A second, similar model is also advanced in which communication difficulties, in particular, are afforded a unique role. Results support the appropriateness of locating L2 WTC within a general transactional framework of cross-cultural adaptation.
Anger is an important dimension of affect and a prominent feature of posttraumatic mental health, but it is commonly overlooked in postdisaster settings. We aimed to examine the distribution and ...implications of significant anger problems in the aftermath of a natural disaster, via analyses of Beyond Bushfires survey data from 736 residents of rural communities 5 years after the 2009 Black Saturday bushfires in Victoria, Australia. Assessments included the five‐item Dimensions of Anger Reaction (DAR‐5) scale along with measures of PTSD, depression, and significant mental illness, and indicators of life satisfaction, suicidality, hostile aggressive behavior, and violence exposure. The results indicated that approximately 10% of respondents from areas highly affected by the bushfires scored above the provisional cutoff criteria for significant anger problems on the DAR‐5, which was a more than 3‐fold increase, OR = 3.26, relative to respondents from areas of low‐to‐moderate bushfire impact. The rates were higher among women, younger participants, and those who were unemployed, and co‐occurred commonly, although not exclusively, with other postdisaster mental health problems. Anger problems were also associated with lower life satisfaction, β = −.31, an 8‐fold increase in suicidal ideation, OR = 8.68, and a nearly 13‐fold increase in hostile aggressive behavior, OR = 12.98. There were associations with anger problems and violence exposure, which were reduced when controlling for covariates, including probable PTSD. The findings provide evidence indicating that anger is a significant issue for postdisaster mental health and should be considered routinely alongside other posttraumatic mental health issues.
Many studies show that long-term poor mental health outcomes for disaster-affected people are predicted by postdisaster stressors. Despite this finding, existing recovery frameworks vary in how these ...stressors are conceptualised. This paper examines community members' subjective perceptions of what they found problematic and useful in their recoveries after the Australian 2009 Black Saturday bushfires, and considers them in the light of these frameworks. We report the findings from responses to semi-structured survey questions as part of the Beyond Bushfires study, 3-4 years after these bushfires (n = 811). Participants identified the biggest problems as managing rebuilding processes and managing their own mental health, memories of the Black Saturday fires, and their concerns for family members. The four most useful supports were family, friends, rebuilding resources, and their community. We found a complex interplay of the same factors operating as both stressors and supports, particularly in relation to family levels of coping.
IMPLICATIONS
Disaster recovery efforts require the simultaneous management of physical rebuilding and human processes.
Families, friends, and neighbours are underestimated resources in postdisaster recovery.
Given the complex interplay of the same factors operating as both stressors and supports, interventions are needed that maximise the positive dimensions of these factors. To manage this complexity, multiple frameworks are needed to guide disaster recovery.

Involvement in voluntary associations is a key form of social capital and plays an especially important role following disaster as a venue for coordination and decision-making for the wider ...community. Yet, relatively little attention has been paid to how group involvement affects mental health, at either the individual or community level. The aim of this study was to assess the impact of involvement in voluntary associations on mental health among residents of bushfire-affected communities. A longitudinal sample of 642 individuals affected by the 2009 Victorian bushfires in south-eastern Australia were surveyed in 2012 and 2014 (3- and 5-years post-disaster). A further subsample (n = 552) of residents residing continuously within 22 bushfire-affected communities were examined for community-level effects using multilevel regression methods. After adjusting for demographics, disaster exposure, and network variables, group involvement at time 1 bore a curvilinear relationship with PTSD at both time points: moderate involvement was most beneficial, with no participation, or high amounts, yielding poorer outcomes. High amounts of group involvement was likewise linked to a greater risk of major depression. Furthermore, communities with higher median levels of group involvement reported lower levels of PTSD symptoms and major depression two years later. With respect to group involvement, more is not always better. For individuals, moderation – if possible – is key. Meanwhile, community-level health benefits come when most people participate to some extent, suggesting that the distribution of involvement across the community is important.
•Moderate levels of group involvement led to decreased PTSD among bushfire-affected residents.•Over involvement in groups and a lack of close interpersonal ties led to greater depression.•Residing in a community in which most people are involved in groups provides an additional benefit.
As part of the shift within second language acquisition (SLA) research toward complex systems thinking, researchers have called for investigations of social network structure. One strand of social ...network analysis yet to receive attention in SLA is network statistical models, whereby networks are explained in terms of smaller substructures of social ties. This article offers an overview and instructive demonstration of exponential random graph models as applied to a cohort of English for Academic Purposes students (N = 75) and their willingness to communicate in the second language (L2 WTC). Results indicate that cross‐cultural ties build off of intracultural ties through triadic closure (meeting through a mutual contact). Furthermore, situational subtypes of L2 WTC are associated with various network tie patterns.
In deterministic models of epidemics, there is a host abundance threshold above which the introduction of a few infected individuals leads to a severe epidemic. Studies of weather-driven animal ...pathogens often assume that abundance thresholds will be overwhelmed by weather-driven stochasticity, but tests of this assumption are lacking. We collected observational and experimental data for a fungal pathogen, Entomophaga maimaiga, that infects the gypsy moth, Lymantria dispar. We used an advanced statistical-computing algorithm to fit mechanistic models to our data, such that different models made different assumptions about the effects of host density and weather on E. maimaiga epizootics (epidemics in animals). We then used Akaike information criterion analysis to choose the best model. In the best model, epizootics are driven by a combination of weather and host density, and the model does an excellent job of explaining the data, whereas models that allow only for weather effects or only for density-dependent effects do a poor job of explaining the data. Density-dependent transmission in our best model produces a host density threshold, but this threshold is strongly blurred by the stochastic effects of weather. Our work shows that host-abundance thresholds may be important even if weather strongly affects transmission, suggesting that epidemiological models that allow for weather have an important role to play in understanding animal pathogens. The success of our model means that it could be useful for managing the gypsy moth, an important pest of hardwood forests in North America.
Burnout is commonly associated with professions that entail a high rate of close relationships with other individuals or groups. This paper explores the association between burnout and interpersonal ...relationships using a relational, social network framework. We collected data on advice-seeking relationships among 102 teachers and administrative staff from a secondary school in Melbourne, Australia. Burnout was measured using the Burnout Assessment Tool and we focused on four core subscales: (1) exhaustion; (2) mental distance; (3) emotional impairment; and (4) cognitive impairment. We applied a particular class of statistical model for social networks called Exponential Random Graph Models (ERGMs) to shed new light on how level of burnout relates to formation of advice relations among school staff. Results indicated that high levels of overall burnout were linked to a higher number of advice-seeking ties among school staff. Additionally, teachers who scored high in cognitive impairment (i.e., difficulties in thinking clearly and learn new things at work) tended to seek and to provide advice to a greater number of others. Finally, school staff who scored high in exhaustion (i.e., a severe loss of energy that results in feelings of both physical and mental exhaustion) tended to be sought out less as advisors to others, while those high in mental distance (i.e., psychologically distancing oneself from others) were generally less likely to seek advice from other school staff. We discuss these findings drawing on Conservation of Resource theory. Notably, our results show that burnout is not only an individual-level problem, but that burnout is associated with reduced social connectivity in specific ways that may impact on how other school staff collaborate, culminating in a staff-wide overall impact that affects how schools function.
