ItemTrajectories of psychological distress over multiple COVID-19 lockdowns in AustraliaBotha, F ; Morris, RW ; Butterworth, P ; Glozier, N (Elsevier, 2023-03-01)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.

ItemMotivation and competition in health careScott, A ; Sivey, P (WILEY, 2022-05-28)Non-pecuniary sources of motivation are a strong feature of the health care sector and the impact of competitive incentives on behavior may be lower where pecuniary motivation is low. This paper measures the marginal utility of income (MUY) of physicians from a stated-choice experiment, and examines whether this measure influences the association between competition faced by physicians and the prices they charge. We find that physicians are more likely to exploit a lack of competition with higher prices if they have a high MUY.

ItemScaling up sanitation: Evidence from an RCT in IndonesiaCameron, L ; Olivia, S ; Shah, M (Elsevier, 2019-05)We investigate the impacts of a widely used sanitation intervention, Community-Led Total Sanitation, which was implemented at scale across rural areas of Indonesia with a randomized controlled trial to evaluate its effectiveness. The program resulted in modest increases in toilet construction, decreased community tolerance of open defecation and reduced roundworm infestations in children. However, there was no impact on anemia, height or weight. We find important heterogeneity along three dimensions: (1) poverty—poorer households are limited in their ability to improve sanitation; (2) implementer identity—scale up involves local governments taking over implementation from World Bank contractors yet no sanitation and health benefits accrue in villages with local government implementation; and (3) initial levels of social capital—villages with high initial social capital built toilets whereas the community-led approach was counterproductive in low social capital villages with fewer toilets being built.

ItemPsychometric Properties of a Risk Tool Across Indigenous Maori and European Samples in Aotearoa New Zealand: Measurement Invariance, Discrimination, and Calibration for Predicting Criminal RecidivismCoulter, DJ ; Lloyd, CD ; Serin, RC (SAGE PUBLICATIONS INC, 2023-02-22)Due to recent legal cases highlighting a lack of cross-ethnicity validity research using correctional risk assessment tools, we evaluated psychometric properties of Dynamic Risk Assessment for Offender Re-entry (DRAOR) scores across Māori (n = 1,812) and New Zealand (NZ) European samples (n = 1,211) in Aotearoa NZ. Using routine administrative data, our analyses suggested scoring properties were invariant across ethnicity for 15 of 19 items. Discrimination properties were also equivalent, but we observed a higher recidivism base rate among Māori participants, consistent with official statistics. Consequently, calibration analyses using a fixed follow-up (N = 372) demonstrated higher predicted recidivism rates for Māori participants at each DRAOR score. This suggests that Māori participants with similar levels of DRAOR-assessed need factors as NZ European participants experienced relatively greater continued justice contact. DRAOR users should prioritize delivering quality case management to clients, recognizing that both case-specific and systemic factors may underlie differential base rates.

ItemUsing a reassessment framework to determine critical case management needs: DRAOR improves on LS/RNR’s predictive discrimination of short-term recidivismCoulter, DJ ; Lloyd, CD (Taylor and Francis Group, 2023)Two core tasks within community corrections are estimating recidivism risk and providing supportive case management to supervised clients. Recent studies demonstrated that regularly reassessing dynamic risk factors enhances the predictive accuracy of case management tools that identify immediate client needs. Using a large sample (N = 2076) of adults on parole in an Australian jurisdiction, we evaluated whether reassessed versus initial scores from Level of Service/Risk, Need, Responsivity (LS/ RNR) and Dynamic Risk Assessment for Offender Re-entry (DRAOR) better discriminated recidivists from non-recidivists. Using Cox regression survival analyses, we modelled risk for general and violent recidivism. Updated DRAOR scores incrementally predicted recidivism beyond initial scores, particularly showing that DRAOR Acute scores can identify needs related to immediate recidivism risk. Models combining LS/RNR criminal history scores with updated DRAOR Acute scores demonstrated the greatest predictive validity, suggesting case managers must consider acute dynamic risk factors within the context of long-term risk. We suggest that attending to criminal history, criminogenic needs and acute dynamic risk factors are each necessary for effective case management, with specific attention toward regularly reassessed acute dynamic risk factors among people identified with higher long-term risk and needs.

ItemUnderstanding the Rising Trend in Female Labour Force ParticipationHerault, N ; Kalb, G (Wiley, 2022-12-28)Female labour force participation has increased tremendously since World War II in developed countries. Prior research provides piecemeal evidence identifying some drivers of change but largely fails to present a consistent story. Using a rare combination of data and modelling capacity available in Australia, we develop a new decomposition approach to explain rising female labour force participation since the mid-1990s. The approach allows us to identify the role of tax and transfer policy reforms as well as three other factors that have been shown to matter by earlier studies: (i) changes in real wages; (ii) population composition changes; and (iii) changes in labour supply preference parameters. For the first time, all these factors are identified through a single consistent decomposition framework. A key result is that – despite the ongoing emphasis of public policy on improved work incentives for women in Australia and elsewhere – changes in financial incentives due to tax and transfer policy reforms have contributed relatively little to achieve these large increases in participation. Instead, the other three factors drive the increased female labour force participation.

ItemMeasuring, Modeling, and Forecasting the Mental Wealth of NationsOcchipinti, J-A ; Buchanan, J ; Skinner, A ; Song, YJC ; Tran, K ; Rosenberg, S ; Fels, A ; Doraiswamy, PM ; Meier, P ; Prodan, A ; Hickie, IB (FRONTIERS MEDIA SA, 2022-07-28)The COVID-19 pandemic has exposed the deep links and fragility of economic, health and social systems. Discussions of reconstruction include renewed interest in moving beyond GDP and recognizing "human capital", "brain capital", "mental capital", and "wellbeing" as assets fundamental to economic reimagining, productivity, and prosperity. This paper describes how the conceptualization of Mental Wealth provides an important framing for measuring and shaping social and economic renewal to underpin healthy, productive, resilient, and thriving communities. We propose a transdisciplinary application of systems modeling to forecast a nation's Mental Wealth and understand the extent to which policy-mediated changes in economic, social, and health sectors could enhance collective mental health and wellbeing, social cohesion, and national prosperity. Specifically, simulation will allow comparison of the projected impacts of a range of cross-sector strategies (education sector, mental health system, labor market, and macroeconomic reforms) on GDP and national Mental Wealth, and provide decision support capability for future investments and actions to foster Mental Wealth. Finally, this paper introduces the Mental Wealth Initiative that is harnessing complex systems science to examine the interrelationships between social, commercial, and structural determinants of mental health and wellbeing, and working to empirically challenge the notion that fostering universal social prosperity is at odds with economic and commercial interests.

ItemThe Impact of the Pandemic on Gender Inequality in the Australian Labor MarketMooi-Reci, I ; Trinh, T-A ; Wooden, M (SAGE PUBLICATIONS INC, 2022-04-01)We examine whether the coronavirus disease 2019 (COVID-19) and the associated policy responses have aggravated gender inequality in the Australian labor market. Using quarterly data from the Australian Labour Force Survey between November 2019 and November 2021, we compare labor force outcomes before and during the outbreak. Our findings indicate that while women fared worse than men in the first few months of the pandemic, labor market recovery was much more rapid for women. By the end of the period, on most indicators, women’s position in the labor market had improved relative to that of men.
