Generational differences in mental health trends in the twenty-first century.

Given the observed deterioration in mental health among Australians over the past decade, this study investigates to what extent this differs in people born in different decades-i.e., possible birth cohort differences in the mental health of Australians. Using 20 y of data from a large, nationally representative panel survey (N = 27,572), we find strong evidence that cohort effects are driving the increase in population-level mental ill-health. Deteriorating mental health is particularly pronounced among people born in the 1990s and seen to a lesser extent among the 1980s cohort. There is little evidence that mental health is worsening with age for people born prior to the 1980s. The findings from this study highlight that it is the poorer mental health of Millennials that is driving the apparent deterioration in population-level mental health. Understanding the context and changes in society that have differentially affected younger people may inform efforts to ameliorate this trend and prevent it continuing for emerging cohorts.

Predictors of male loneliness across life stages: an Australian study of longitudinal data.

BACKGROUND: Despite growing recognition of loneliness as a global public health concern, research on its occurrence and precipitants among men across different life stages remains limited and inconclusive. This study aims to address this gap by investigating the prevalence and predictors of loneliness among a large, representative data set of Australian adult men. METHODS: The study used longitudinal data from waves 2-21 of the Household, Income and Labour Dynamics in Australia (HILDA) Survey, including men aged 15-98. Estimating linear fixed effects regressions that account for unobserved time-invariant individual heterogeneity, a single-item measure of loneliness was regressed on a set of selected explanatory variables over different parts of the life course. RESULTS: Increased social isolation, romantic partnership dissolution, having a long-term disability, and stronger beliefs that the man, rather than the woman, should be the breadwinner of the household, are associated with greater loneliness. Frequent social connection, having a romantic partner, and high neighbourhood satisfaction are protective against loneliness. The findings also reveal several differences in the predictors of loneliness over the life course. Job security is especially important for younger men, whereas for older men volunteering and less conservative gender role attitudes are important factors that can decrease loneliness. CONCLUSIONS: The results emphasise the need to consider age-specific factors and societal expectations in understanding and addressing loneliness amongst men. Additionally, the findings underscore the importance of raising awareness about the impact of societal norms and expectations on men's mental health. The results offer valuable insights for policymakers, healthcare providers, and researchers to develop effective strategies and support systems to combat loneliness and promote well-being among men.

Conceptual causal models of socioeconomic status, family structure, family functioning and their role in public health.

Social determinants of health frameworks are standard tools in public health. These frameworks for the most part omit a crucial factor: the family. Socioeconomic status moreover is a prominent social determinant of health. Insofar as family functioning is poorer in poor families and family structure and functioning are linked to health, it is critical to consider the pathways between these four constructs. In this correspondence, we reflect on how empirical studies of this conceptual nexus mirror two causal models. We conclude by reflecting on future directions for research in this field.

Locus of control, self-control, and health outcomes.

We provide the first empirical evidence on the direct link between locus of control and self-control, and how they interact in explaining a range of health outcomes. Using rich Australian survey data, we find that, while the two traits are distinct constructs, a greater internal locus of control is associated with higher self-control. The association between locus of control and health is reduced once we control for self-control, suggesting that self-control mediates at least part of this relationship. Finally, an internal locus of control amplifies the beneficial effects of self-control particularly for physical health.

Testing the Impact of Variations in Administration on the Kessler Psychological Distress Scale (K10).

Self-report measures are useful in psychological research and practice, but scores may be impacted by administration methods. This study investigated whether changing the recall period (from 30 to 7 days) and response option order (from ascending to descending) alters the score distribution of the Kessler Psychological Distress Scale (K10). Participants were presented with the K10 with either different recall periods or different response option orders. There was weak evidence of lower mean K10 scores when using a 7-day recall period than when using the 30-day recall period (B = 1.96, 95% CI [0.04-3.90]) but no evidence of a change in the estimated prevalence of very high psychological distress. Presenting the response options in ascending order did not affect mean scores, but there was weak evidence of reduced prevalence of very high distress relative to the descending order (incidence rate ratio [IRR] = 0.60, 95% CI [0.36-0.98]). These findings suggest that varying the administration method may result in minor differences in population estimates of very high psychological distress when using the K10.

Trajectories of psychological distress over multiple COVID-19 lockdowns in Australia.

The impact of the global COVID-19 pandemic, including the indirect effect of policy responses, on psychological distress has been the subject of much research. However, there has been little consideration of how the prevalence of psychological distress changed with the duration and repetition of lockdowns, or the rate of resolution of psychological distress once lockdowns ended. This study describes the trajectories of psychological distress over multiple lockdowns during the first two years of the pandemic across five Australian states for the period May 2020 to December 2021 and examines whether psychological distress trajectories varied as a function of time spent in lockdown, or time since lockdown ended. A total of N = 574,306 Australian adults completed Facebook surveys over 611 days (on average 940 participants per day). Trajectories of psychological distress (depression and anxiety) were regressed on lockdown duration and time since lockdown ended. Random effects reflecting the duration of each lockdown were included to account for varying effects on psychological distress associated with lockdown length. The prevalence of psychological distress was higher during periods of lockdown, more so for longer lockdowns relative to shorter lockdowns. Psychological distress increased rapidly over the first ten weeks of lockdowns spanning at least twelve weeks, though less rapidly for short lockdowns of three weeks or less. Psychological distress levels tended to stabilise, or even decrease, after ten consecutive weeks of lockdown. After lockdown restrictions were lifted, psychological distress rapidly subsided but did not return to pre-lockdown levels within four weeks, although continued to decline afterwards. In Australia short lockdowns of pre-announced durations were associated with slower rises in psychological distress. Lockdowns may have left some temporary residual population effect, but we cannot discern whether this reflects longer term trends in increasing psychological distress. However, the findings do re-emphasise the resilience of individuals to major life stressors.

Vulnerability and recovery: Long-term mental and physical health trajectories following climate-related disasters.

Extreme weather and climate-related disaster events are associated with a range of adverse health outcomes. People are not equally vulnerable to the adversity, experiencing varied patterns of long-term health trajectories in recovery depending on their vulnerabilities, capacities, and resiliencies. This study aims to identify latent mental and physical health trajectories and their associations with person- and place-based pre-disaster predictors. Using an Australian, population-based, longitudinal dataset spanning 2009-19, group-based multi-trajectory modelling was applied to identify the distinct mental, social, emotional, and physical health trajectories of people who had experienced damage to their home following a climate-related disaster event. Multinomial logistic regression was used to assess a series of social vulnerability predictors (demographic, socioeconomic, housing, health, neighbourhood, and geographical) of health patterns. We identified three distinct health trajectories. Most individuals experienced small or minimal health impacts at the time of the disaster year followed by a fast recovery. However, one-fifth of the exposed population were severely affected during and post disaster. This cohort had the worst mental and physical health prior to the disaster and experienced the largest decreases in mental and physical health and the lowest recoveries. Pre-existing mental and physical conditions were the most substantial risk factors, increasing the probability of experiencing high impact and slow recovery by 61% for mental health and 51% for physical health. In addition, vulnerability in the form of housing affordability stress, lower household income, and lack of community attachment, participation and safety were also significant independent risk factors for ongoing post-disaster health problems. Critically, people's mental and physical health recovery is dependent on pre-disaster vulnerabilities in health, resource access, and capacities. These findings could assist policymakers and health practitioners to more effectively target people most at risk and design prevention and response strategies to prevent the exacerbation of poor health and wellbeing.

Comparing estimates of psychological distress using 7-day and 30-day recall periods: Does it make a difference?

Self-report measures are widely used in mental health research and may use different recall periods depending on the purpose of the assessment. A range of studies aiming to monitor changes in mental health over the course of the COVID-19 pandemic opted to shorten recall periods to increase sensitivity to change over time compared to standard, longer recall periods. However, many of these studies lack pre-pandemic data using the same recall period and may rely on pre-existing data using standard recall periods as a reference point for assessing the impact of the pandemic on mental health. The aim of this study was to assess whether comparing scores on the same questionnaire with a different recall period is valid. A nationally representative sample of 327 participants in Australia completed a 7-day and 30-day version of the six-item Kessler Psychological Distress Scale (K6) and a single-item measure of psychological distress (TTPN item) developed for the Taking the Pulse of the Nation survey. Linear mixed models and mixed logistic regression models were used to assess whether altering the recall period systematically changed response patterns within subjects. No substantive recall period effects were found for the K6 or the TTPN, although there was a trend towards higher K6 scores when asked about the past 30 days compared to the past 7 days (b = 1.00, 95% CI: -0.18, 2.17). This may have been driven by the "feeling nervous" item which was rated higher using the 30-day compared to the 7-day recall period. Neither the K6 nor the TTPN item were significantly affected by the recall period when reduced to a binary variable of likely severe mental illness. The results indicate that altering the recall period of psychological distress measures does not substantively alter the score distribution in the general population of Australian adults.

Opposite nonlinear effects of unemployment and sentiment on male and female suicide rates: Evidence from Australia.

We investigate gender differences in the effects of unemployment and sentiment on suicide rates. Using monthly Australian data, we find a positive relationship between the unemployment rate and the suicide rate, and a negative relationship between consumer sentiment and the suicide rate. However, there is strong evidence of nonlinearity in the effects of both unemployment and sentiment on suicide rates, with substantial gender differences. For men, an increase in the unemployment rate increases the suicide rate, but an unemployment decrease has no effect; we find the opposite for women. For men, an increase in sentiment has stronger effects on the suicide rate than a decrease in sentiment. Again, we observe the opposite effect for women. Among sentiment components, forward-looking expectations are stronger predictors of suicide rates than present conditions. Sentiment has a much stronger effect on male suicide rates than on female suicide rates.

Evaluating How Mental Health Changed in Australia through the COVID-19 Pandemic: Findings from the 'Taking the Pulse of the Nation' (TTPN) Survey.

The COVID-19 pandemic has had a significant impact on mental health at the level of the population. The current study adds to the evidence base by examining how the prevalence of psychological distress changed in Australia during the pandemic. The study also assesses the psychometric properties of a new single-item measure of mental distress included in a survey program conducted regularly throughout the pandemic. Data are from 1158 respondents in wave 13 (early July 2020) of the nationally representative Taking the Pulse of the Nation (TTPN) Survey. The questionnaire included the six-item Kessler Psychological Distress Scale (K6) and a new single-item measure of distress. Results show a significant increase in the prevalence of psychological distress in Australia, from 6.3% pre-pandemic to 17.7% in early July 2020 (unadjusted odds ratio = 3.19; 95% CI (confidence interval) = 2.51 to 4.05). The new single-item measure of distress is highly correlated with the K6. This study provides a snapshot at one point in time about how mental health worsened in Australia during the COVID-19 pandemic. However, by demonstrating the accuracy of the new single-item measure of distress, this analysis also provides a basis for further research examining the trajectories and correlates of distress in Australia across the pandemic.

Protecting mental health during periods of financial stress: Evidence from the Australian Coronavirus Supplement income support payment.

This paper investigates whether the Australian government's Coronavirus Supplement, a temporary income support payment for unemployed jobseekers during the height of the COVID-19 pandemic, protected mental health (frequency of feeling anxious or depressed during the past week) by lowering financial stress (how comfortable people are in paying for essential services). We use unique nationally representative repeated cross-sectional data on 3843 unemployed Australian adults over the period April 6, 2020 to May 10, 2021. We find that the Coronavirus Supplement payment significantly reduced reported financial stress, and lower financial stress was associated with lower mental distress. Though the Coronavirus Supplement was designed to reduce financial stress, we find the Supplement was also successful in protecting community mental health indirectly via its ability to reduce financial stress. The findings provide support for income support packages to protect mental health during economic shocks. However, transitory support measures also tend have short-lived positive effects on mental health, suggesting that more permanent income support reform may have longer-term mental health benefits.

Implications of COVID-19 labour market shocks for inequality in financial wellbeing.

Australia's economy abruptly entered into a recession due to the COVID-19 pandemic of 2020. Related labour market shocks on Australian residents have been substantial due to business closures and social distancing restrictions. Government measures are in place to reduce flow-on effects to people's financial situations, but the extent to which Australian residents suffering these shocks experience lower levels of financial wellbeing, including associated implications for inequality, is unknown. Using novel data we collected from 2078 Australian residents during April to July 2020, we show that experiencing a labour market shock during the pandemic is associated with a 29% lower level of perceived financial wellbeing, on average. Unconditional quantile regressions indicate that lower levels of financial wellbeing are present across the entire distribution, except at the very top. Distribution analyses indicate that the labour market shocks are also associated with higher levels of inequality in financial wellbeing. Financial counselling and support targeted at people who experience labour market shocks could help them to manage financial commitments and regain financial control during periods of economic uncertainty.
