Objectives
To systematically assess whether economic, social and community resources can protect against the impact of the Australian “ Black Summer” bushfires on adolescent psychological distress. Using 16 years of longitudinal data, we also test whether history of mental health problems, history of economic hardship puts youth at risk and whether a history of high parental warmth and low harsh parenting protects young people.
Study design
Prospective, population-based cohort study; analysis of Longitudinal Study of Australian Children (LSAC) survey data
Setting, participants
Adolescents in the nationally representative cross-sequential sample of Australian children recruited in 2004 for the Birth and Kindergarten cohort (aged 0-1 and 4-5 years at enrolment). Survey data from waves 9 (16-17 and 18-19 years for B and K Cohort) and waves 1 to 8
Main outcome measures
Psychological distress measured by the Kessler 10-item questionnaire, K10.
Results
There were 2,726 respondents from the B and K Cohorts who had psychological distress information and demographic characteristics in Wave 9. We did not find that a history of financial hardship, unemployment, being partnered, high social support, household harmony and additional stressful life events moderated the association between fires and psychological distress. Family financial hardship or capacity to raise $2000 in an emergency in the previous wave, or over the prior 16 years did not increase or reduce the risk. Community collective efficacy, and history of positive parenting (high warmth, low harshness) was also not significant. History of high anxiety but not depressed mood was the only significant risk or protective factor. Those with a significant history of high anxiety had elevated distress levels when exposed to fire in the last 12 months compared to those with none or some history of high anxiety.
Conclusions
Additional targeted support for youth for those with prior history of anxiety through the Better Access initiative may be particularly important. However, our findings do underscore that leaving prior mental health history aside, how robust the impacts of bushfires were on youth mental health and that being exposed to the Black Summer bushfires affected all youth irrespective of privilege or social address.
