COVID-19 and mental health in Australia - a scoping review.

BACKGROUND: The COVID-19 outbreak has spread to almost every country around the world and caused more than 3 million deaths. The pandemic has triggered enormous disruption in people's daily lives with profound impacts globally. This has also been the case in Australia, despite the country's comparative low mortality and physical morbidity due to the virus. This scoping review aims to provide a broad summary of the research activity focused on mental health during the first 10 months of the pandemic in Australia. RESULTS: A search of the Australian literature was conducted between August-November 2020 to capture published scientific papers, online reports and pre-prints, as well as gaps in research activities. The search identified 228 unique records in total. Twelve general population and 30 subpopulation group studies were included in the review. CONCLUSIONS: Few studies were able to confidently report changes in mental health driven by the COVID-19 context (at the population or sub-group level) due to a lack of pre-COVID comparative data and non-representative sampling. Never-the-less, in aggregate, the findings show an increase in poor mental health over the early period of 2020. Results suggest that young people, those with pre-existing mental health conditions, and the financially disadvantaged, experienced greater declines in mental health. The need for rapid research appears to have left some groups under-researched (e.g. Culturally and Linguistically Diverse populations and Indigenous peoples were not studied), and some research methods under-employed (e.g. there was a lack of qualitative and mixed-methods studies). There is a need for further reviews as the follow-up results of longitudinal studies emerge and understandings of the impact of the pandemic are refined.

Australian parents' work-family conflict: accumulated effects on children's family environment and mental health.

PURPOSE: Many parents struggle to balance their work and family responsibilities. Yet, little research in the field of social psychiatry has explored the emergence of work-family conflict (WFC) as an important social determinant of mental health, particularly for children. The current study used longitudinal Australian population-based data to investigate the impact of parents' accumulated experiences of work-family conflict on children's mental health. Levels of parent psychological distress, marital satisfaction and parenting irritability were examined as potential explanatory factors within the family environment. METHODS: The study used five waves of data from the Australian Longitudinal Study of Australian Children (LSAC), a representative community sample of Australian children and their parents. Analyses were restricted to coupled, employed mothers (1903) and fathers (1584) who reported their WFC levels in all five waves. Structural Equation Modelling (SEM) was used to examine the association between accumulated experiences of work-family conflict across all time-points (AWFC) and children's mental health at wave 5. Family environment factors were assessed as possible explanatory mediators. RESULTS: There was a significant association between AWFC and children's mental health at wave 5. Parent psychological distress, marital satisfaction and parenting irritability were all found to significantly explain this association (accounting for 66% of the total effect). CONCLUSIONS: Children whose parents have ongoing or accumulated difficulties managing their work and family responsibilities are more likely to have poorer mental health. This has important implications for family-friendly work arrangements and demonstrates the need to further understand the intergenerational impacts of parents' jobs on their children's psychological wellbeing.

Shift work and mental health: a systematic review and meta-analysis.

BACKGROUND: Shift work is common. However, research findings are mixed regarding the impact of shift work on mental health. This systematic review sought to provide a comprehensive summary of existing research examining the association between different types of shift work and mental health. The review included large-scale, non-occupation-specific research. METHODS: Four electronic databases PubMed, PsycINFO, Web of Science and SCOPUS were searched to identify studies that reported on the statistical association between shift work and mental health and that used population-based samples. Two reviewers extracted information about study characteristics and data on the association between shift work and mental health. A meta-analysis was performed for longitudinal studies adopting a 'broad binary' measure of shift work. RESULTS: Thirty-three studies were included in the final review-10 cross-sectional studies, 22 longitudinal studies, and 1 study that included both. Findings were grouped based on whether the measure of shift work focussed on: (1) night/evening work, (2) weekend work, (3) irregular/unpredictable work schedule, or (4) a broad binary measure. There was a reasonable level of evidence that overall, when a broad binary measure was adopted, shift work was associated with poorer mental health-this finding was supported by the meta-analysis results. There was also some evidence that irregular/unpredictable work was associated with poorer mental health. There was less evidence for night/evening and minimal evidence for weekend work. Inconsistencies in study methodology, limited contrasting and combining the results. CONCLUSIONS: The association between shift work and mental health is different across types of shift work. The evidence is strongest for a broad binary, general measure of shift work and for irregular or unpredictable shift work. There is a need for continued research that adopts consistent and clear measures of shift work.

Using Paid and Free Facebook Methods to Recruit Australian Parents to an Online Survey: An Evaluation.

BACKGROUND: The prevalence of social media makes it a potential alternative to traditional offline methods of recruiting and engaging participants in health research. Despite burgeoning use and interest, few studies have rigorously evaluated its effectiveness and feasibility in terms of recruitment rates and costs, sample representativeness, and retention. OBJECTIVE: This study aimed to determine the feasibility of using Facebook to recruit employed Australian parents to an online survey about managing work and family demands, specifically to examine (1) recruitment rates and costs; (2) sample representativeness, compared with a population-based cohort of parents; and (3) retention, including demographic and health characteristics of parents who returned to complete a follow-up survey 6 weeks later. METHODS: Recruitment was conducted using 20 paid Facebook advertising campaigns, supplemented with free advertising approaches such as posts on relevant Facebook pages and requests for professional networks to circulate the survey link via Facebook. Recruitment rates and costs were evaluated using the Checklist for Reporting Results of Internet E-Surveys, including view rate, participation rate, completion rate, cost per consent, and cost per completer. Sample representativeness was evaluated by comparing demographic and outcome variables with a comparable sample from the Longitudinal Study of Australian Children including educational attainment, marital status, country of birth, neighborhood disadvantage, work-family conflict, and psychological distress. Retention was evaluated by comparing the number and demographic characteristics of participants at recruitment and at 6-week follow-up. RESULTS: Recruitment strategies together resulted in 6653 clicks on the survey link, from which 5378 parents consented to participate and 4665 (86.74%) completed the survey. Of those who completed the survey, 85.94% (4009/4665) agreed to be recontacted, with 57.79% (2317/4009) completing the follow-up survey (ie, 43.08% [2317/5378] of parents who consented to the initial survey). Paid Facebook advertising recruited nearly 75% of the sample at Aus $2.32 per completed survey (Aus $7969 spent, 3440 surveys completed). Compared with a population-based sample, participants at baseline were more likely to be university educated (P<.001), experience greater work-family conflict (P<.001) and psychological distress (P<.001), and were less likely to be born outside Australia (P<.001) or live in a disadvantaged neighborhood (P<.001). CONCLUSIONS: Facebook provided a feasible, rapid method to recruit a large national sample of parents for health research. However, some sample biases were observed and should be considered when recruiting participants via Facebook. Retention of participants at 6- to 8-week follow-up was less than half the initial sample; this may reflect limited ongoing participant engagement for those recruited through social media, compared with face-to-face.

Recruiting fathers for parenting research using online advertising campaigns: Evidence from an Australian study.

BACKGROUND: Fathers are underrepresented in parenting and child health research. Given there is a strong link between fathers' parenting behaviour and children's well-being, there is a need to find ways to engage fathers more consistently. The current short report provides information and learnings about recruiting fathers online using social media. Results are drawn from an Australian study that aimed to recruit roughly equal numbers of mothers and fathers to participate in a survey about employment, parenting, and health, using online advertising. METHODS: First, a series of five Facebook advertising campaigns were run, aimed at "parents" generally (i.e., gender-neutral). A lack of recruited fathers prompted a second series of six Facebook campaigns aimed solely at fathers. All campaigns targeted employed adult parents of children (≤18 years) in Australia using Facebook's "Adverts Manager." RESULTS: The 11 campaigns recruited a total of 1,468 fathers. The vast majority of these fathers were recruited using the advertisements specifically aimed at fathers (n = 1,441). Gender-neutral campaigns inviting and selecting "parents" to participate in the study overwhelmingly yielded samples of mothers. Similarly, advertisements inviting both "mums and dads" resulted in very low recruitment of fathers. CONCLUSIONS: The extremely low numbers of fathers recruited using the gender-neutral "parent-focused" campaigns was unexpected. Potential reasons for this include low engagement with gender-neutral parenting terms, and/or that mothers were disproportionally exposed to the Facebook advertisements. These learnings suggest that father-focused recruitment is required to target and engage fathers in parenting research and services.

Comorbid anxiety and depression: a community-based study examining symptomology and correlates during the postpartum period.

Background: Despite indications that anxiety and depression co-occur frequently within the postpartum period, studies identifying the correlates associated with this comorbidity are rare. Objective: This study assessed variation in social and maternal circumstances, based on comorbid anxiety and depression symptomology. Methods: A large community-based sample of 1070 Australian postpartum women completed the Living with a Young Baby online survey. Mothers were categorised into groups: (a) comorbid anxiety and depression symptomology, (b) anxiety only, (c) depression only, or (d) neither depression nor anxiety. Multinomial Logistic Regression (MLR) investigated variation in correlates between the groups. Results: Comorbid anxiety and depression symptomology was common (13.4%), and was associated with greater symptom severity. Women in the 'comorbid' group more often experienced financial hardship, cessation of breastfeeding, infants with difficult temperaments, inadequate social support or help, and stressful adverse life events in comparison to mothers in the 'neither symptomology' group. They were also more likely to have infants with difficult temperaments compared to the depression only group, and to receive inadequate help and support compared to the anxiety only group. Conclusions: Comorbid anxiety and depression symptomology is common postpartum and is associated with considerable adversity across a wide range of demographic, economic and social correlates.

Early Onset of Distress Disorders and High-School Dropout: Prospective Evidence From a National Cohort of Australian Adolescents.

Prior research examining whether depression and anxiety lead to high-school dropout has been limited by a reliance on retrospective reports, the assessment of mental health at a single point in time (often remote from the time of high-school exit), and the omission of important measures of the social and familial environment. The present study addressed these limitations by analyzing 8 waves of longitudinal data from a cohort of Australian adolescents (n = 1,057) in the Household, Income and Labor Dynamics in Australia (HILDA) Survey (2001-2008). Respondents were followed from the age of 15 years through completion of or exit from high school. Discrete-time survival analysis was used to assess whether the early experience of a distress disorder (indicated by scores <50 on the 5-item Mental Health Inventory from the Short Form Health Survey) predicted subsequent high-school dropout, after controlling for household and parental socioeconomic characteristics and for tobacco smoking and alcohol consumption. Adolescents with a prior distress disorder had twice the odds of high-school dropout compared with those without (odds ratio = 1.99, 95% confidence interval: 1.24, 3.17). This association was somewhat attenuated but remained significant in models including tobacco and alcohol consumption (odds ratio = 1.74, 95% confidence interval: 1.74; 1.09, 2.78). These results suggest that improving the mental health of high-school students may promote better educational outcomes.

Workplace bullying and the association with suicidal ideation/thoughts and behaviour: a systematic review.

The established links between workplace bullying and poor mental health provide a prima facie reason to expect that workplace bullying increases the risk of suicidal ideation (thoughts) and behaviours. Until now, there has been no systematic summary of the available evidence. This systematic review summarises published studies reporting data on workplace bullying and suicidal ideation, or behaviour. The review sought to ascertain the nature of this association and highlight future research directions. 5 electronic databases were searched. 2 reviewers independently selected the articles for inclusion, and extracted information about study characteristics (sample, recruitment method, assessment and measures) and data reporting the association of workplace bullying with suicidal ideation and behaviour. 12 studies were included in the final review-8 reported estimates of a positive association between workplace bullying and suicidal ideation, and a further 4 provided descriptive information about the prevalence of suicidal ideation in targets of bullying. Only 1 non-representative cross-sectional study examined the association between workplace bullying and suicidal behaviour. The results show an absence of high-quality epidemiological studies (eg, prospective cohort studies, which controlled for workplace characteristics and baseline psychiatric morbidity). While the available literature (predominantly cross-sectional) suggests that there is a positive association between workplace bullying and suicidal ideation, the low quality of studies prevents ruling out alternative explanations. Further longitudinal, population-based research, adjusting for potential covariates (within and outside the workplace), is needed to determine the level of risk that workplace bullying independently contributes to suicidal ideation and behaviour.

Online Recruitment: Feasibility, Cost, and Representativeness in a Study of Postpartum Women.

BACKGROUND: Online recruitment is feasible, low-cost, and can provide high-quality epidemiological data. However, little is known about the feasibility of recruiting postpartum women online, or sample representativeness. OBJECTIVE: The current study investigates the feasibility of recruiting a population of postpartum women online for health research and examines sample representativeness. METHODS: Two samples of postpartum women were compared: those recruited online as participants in a brief survey of new mothers (n=1083) and those recruited face-to-face as part of a nationally representative study (n=579). Sociodemographic, general health, and mental health characteristics were compared between the two samples. RESULTS: Obtaining a sample of postpartum women online for health research was highly efficient and low-cost. The online sample over-represented those who were younger (aged 25-29 years), were in a de facto relationship, had higher levels of education, spoke only English at home, and were first-time mothers. Members of the online sample were significantly more likely to have poor self-rated health and poor mental health than the nationally representative sample. Health differences remained after adjusting for sociodemographic differences. CONCLUSIONS: Potential exists for feasible and low-cost e-epidemiological research with postpartum populations; however, researchers should consider the potential influence of sample nonrepresentativeness.

Why it's important for it to stop: Examining the mental health correlates of bullying and ill-treatment at work in a cohort study.

OBJECTIVE: There is limited Australian information on the prevalence and mental health consequences of bullying and ill-treatment at work. The aims of this study were to use data from an ongoing Australian longitudinal cohort study to (1) compare different measures of workplace bullying, (2) estimate the prevalence of bullying and ill-treatment at work, (3) evaluate whether workplace bullying is distinct from other adverse work characteristics and (4) examine the unique contribution of workplace bullying to common mental disorders in mid-life. METHOD: The sample comprised 1466 participants (52% women) aged 52-58 from wave four of the Personality and Total Health (PATH) through Life study. Workplace bullying was assessed by a single item of self-labelling measure of bullying and a 15-item scale of bullying-related behaviours experienced in the past 6 months. Factor analysis the identified underlying factor structure of the behavioural bullying scale. RESULTS: Current bullying was reported by 7.0% of respondents, while 46.4% of respondents reported that they had been bullied at some point in their working life. Person-related and work-related bullying behaviours were more common than violence and intimidation. The multi-dimensional scale of bullying behaviours had greater concordance with a single item of self-labelled bullying (Area Under the Curve = 0.88) than other adverse work characteristics (all Area Under the Curves < 0.67). Self-labelled bullying and scales reflecting person-related and work-related bullying were independent predictors of depression and/or anxiety. CONCLUSION: This study provides unique information on the prevalence and mental health impacts of workplace bullying and ill-treatment in Australia. Workplace bullying is a relatively common experience, and is associated with increased risk of depression and anxiety. Greater attention to identifying and preventing bullying and ill-treatment in the workplace is warranted.

Depression and anxiety in expectant and new fathers: longitudinal findings in Australian men.

BACKGROUND: Despite growing interest in men's perinatal mental health, we still know little about whether becoming a new father is associated with increases in psychological distress. AIMS: To use prospective longitudinal data to investigate whether becoming a first-time expectant (partner pregnant) and/or new father (child <1 year) is associated with increases in depression and anxiety. METHOD: Men were aged 20-24 years at baseline (n = 1162). Levels of depression and anxiety were measured at four time points over 12 years. Over this time, 88 men were expectant fathers, 108 men were new fathers and 626 men remained non-fathers. RESULTS: Longitudinal mixed models showed no significant increase in depression or anxiety as a function of expectant or new fatherhood, as compared with pre-fatherhood levels. CONCLUSIONS: Our findings suggest that, generally, expectant and new fathers are not at greater risk of depression or anxiety. Future epidemiological research should continue to identify men who are most (and least) at risk to focus resources and assistance most effectively.

How financial hardship is associated with the onset of mental health problems over time.

PURPOSE: Poor mental health has been consistently linked with the experience of financial hardship and poverty. However, the temporal association between these factors must be clarified before hardship alleviation can be considered as an effective mental health promotion and prevention strategy. We examined whether the longitudinal associations between financial hardship and mental health problems are best explained by an individual's current or prior experience of hardship, or their underlying vulnerability. METHODS: We analysed nine waves (years: 2001-2010) of nationally representative panel data from the Household, Income, and Labour Dynamics in Australia survey (n = 11,134). Two components of financial hardship (deprivation and cash-flow problems) and income poverty were coded into time-varying and time-invariant variables reflecting the contemporaneous experience of hardship (i.e., current), the prior experience of hardship (lagged/12 months), and any experience of hardship during the study period (vulnerability). Multilevel, mixed-effect logistic regression models tested the associations between these measures and mental health. RESULTS: Respondents who reported deprivation and cash-flow problems had greater risk of mental health problems than those who did not. Individuals vulnerable to hardship had greater risk of mental health problems, even at the times they did not report hardship. However, their risk of mental health problems was greater on occasions when they did experience hardship. CONCLUSIONS: The results are consistent with the argument that economic and social programmes that address and prevent hardship may promote community mental health.

New fatherhood and psychological distress: a longitudinal study of Australian men.

Despite growing interest and concern about men's mental health during the perinatal period, we still do not know whether men are more vulnerable to mental health problems during this time. The current study is one of the first to use longitudinal, population-based data to investigate whether becoming an expectant and/or new father is associated with increases in psychological distress. We analyzed 10 waves of data collected annually (from 2001 to 2010) from the nationally representative Household, Income, and Labour Dynamics in Australia (HILDA) Survey. Over this time, 349 men were identified as new fathers (first child aged <1 year), and 224 of these men had been identified as "expectant fathers" during the previous wave. A total of 1,658 men remained "never fathers." Psychological distress was measured using the 5-item Mental Health Inventory before the partner's pregnancy, during the partner's pregnancy, and during the first year of fatherhood. Longitudinal mixed models showed no significant increase in psychological distress as a function of expectant or new fatherhood; instead, some improvement in mental health was observed. The finding suggests that expectant and new fathers are not at greater risk of poor mental health. Future epidemiologic research should continue to identify those men who are most (and least) at risk during the perinatal period in order to target resources and assistance most effectively.

Pregnancy and levels of depression and anxiety: a prospective cohort study of Australian women.

OBJECTIVE: The effects of pregnancy on depression and anxiety remain unclear. Previous research is predominantly cross-sectional, not representative of the general community, and does not include data on mental health prior to pregnancy. This study used longitudinal Australian population-based data to examine whether pregnancy is associated with increases in women's anxiety and depression levels (from pre-pregnancy). METHOD: A community sample of Australian women aged 20-24 years were recruited prospectively and assessed in 1999, 2003 and 2007. At the follow-up assessments 76 women were pregnant (with no prior children) and 542 remained nulliparous. Mixed models repeated measures analyses of variance were undertaken to compare change in levels of anxiety and depression (Goldberg Anxiety and Depression scales) between those who became pregnant and those who remained non-pregnant. RESULTS: Pregnancy was not associated with increased symptoms of depression or anxiety. No association was found with depression, while pregnancy was associated with a decrease in anxiety. Including somatic items in the measures of depression and anxiety resulted in higher symptom levels in pregnancy, suggesting possible item bias. CONCLUSIONS: This study is one of the first to follow a community sample of women from pre-pregnancy to pregnancy. The findings suggest that pregnancy is not typically detrimental to women's mental health. The current study offers a starting point for future prospective studies to follow women from pre-pregnancy to postpartum. Study limitations to be improved upon in follow-up research include expanding the sample size, and including both pregnancy-specific measures and trimester-specific data. Future research should continue to identify those women who are most (and least) at risk during pregnancy in order to target resources and assistance most effectively.

Mental health affects future employment as job loss affects mental health: findings from a longitudinal population study.

BACKGROUND: Workforce participation is a key feature of public mental health and social inclusion policies across the globe, and often a therapeutic goal in treatment settings. Understanding the reciprocal relationship between participation and mental health has been limited by inadequate research methods. This is the first study to simultaneously examine and contrast the relative effects of unemployment on mental health and mental health on employment status in a single general population sample. METHOD: Data were from working-age respondents (20 to 55 years at baseline) who completed nine waves of the Household, Income and Labour Dynamics in Australia (HILDA) Survey (N=7176). Cross-lagged path analyses were used to test the lagged and concurrent associations between unemployment and mental health over time, adjusting for sociodemographic characteristics. RESULTS: Mental health was shown to be both a consequence of and risk factor for unemployment. Thus, the poorer mental health observed amongst people who are not working is attributable to both the impact of unemployment and existing mental health problems. While the strength of these two effects was similar for women, the results for men suggested that the effect of unemployment on subsequent mental health was weaker than the effect of mental health on subsequent risk of unemployment. CONCLUSION: Disentangling the reciprocal links between mental health and workforce participation is central to the development and success of clinical goals and health and social policies that aim to promote either aspect. This study demonstrates that both effects are important and supports concurrent responses to prevent a cycle of disadvantage and entrenched social exclusion.

Relationship quality and levels of depression and anxiety in a large population-based survey.

PURPOSE: There is substantial literature suggesting that the mental health benefits of marriage (compared to being single) are greater for those in 'good-quality' relationships in comparison to those in 'poor-quality' relationships. However, little of this research utilises large population-based surveys. Large surveys in psychiatric epidemiology have focused almost exclusively on the association between marital status and mental health. The current study explores some of the reasons for this gap in the literature, and adopts a large, representative community-based sample to investigate whether associations between relationship status and levels of depression and anxiety are moderated by relationship quality. METHODS: Participants were from Wave 3 of the PATH Survey, a longitudinal community survey assessing the health and well-being of residents of the Canberra region, Australia (n = 3,820). Relationship quality was measured using the 7 item dyadic adjustment scale (DAS-7), and levels of depression and anxiety were measured using the Goldberg scales. RESULTS: Both cross-sectional and prospective analyses showed that associations between relationship status and mental health were moderated by relationship quality for both men and women, such that only good-quality relationships bestowed mental health benefits over remaining single. For women, being in a poor-quality relationship was associated with greater levels of anxiety than being single. CONCLUSIONS: Epidemiological studies need to measure relationship quality to qualify the effect of relationship status on mental health.

Private health insurance, mental health and service use in Australia.

OBJECTIVE: To report on the private health insurance (PHI) status of individuals with and without a mental health problem, and examine whether PHI status is associated with access to psychological services. METHODS: This is a descriptive study of nationally representative population-based data collected in 2009 (HILDA) with participants aged 15-93 (n = 13,301). Key measures included: PHI status (categorised as 'hospital cover only', 'extras cover only', or 'both hospital and extras cover'); mental health status (categorised as 'have a mental health problem' or 'do not have a mental health problem' using the mental health index (MHI) of the medical outcomes study short form); mental health service use (access to a mental health professional (psychologist/psychiatrist) in the past 12 months categorised as 'yes' or 'no'). RESULTS: Individuals with a mental health problem were less likely to have PHI than those without a mental health problem. However, PHI was not associated with access to a mental health professional in the past 12 months. CONCLUSIONS: The findings suggest that while the discrepancy in PHI status is a marker of inequity between those with and without a mental health problem, it is not a key factor in facilitating access to mental health services.

The role of hardship in the association between socio-economic position and depression.

OBJECTIVE: It is well established that socio-economic position is associated with depression. The experience of financial hardship, having to go without the essentials of daily living due to limited financial resources, may explain the effect. However, there are few studies examining the link between financial hardship and diagnosable depression at a population level. The current paper addresses this gap and also evaluates the moderating effect of age. METHOD: Data were from 8841 participants aged 16-85 years in Australia's 2007 National Survey of Mental Health and Wellbeing. The 12-month prevalence of depressive episode was assessed using the Composite International Diagnostic Interview. Measures of socio-economic position included: financial hardship, education, labour-force status, occupational skill, household income, main source of income, and area-level disadvantage. RESULTS: Financial hardship was more strongly associated with depression than other socio-economic variables. Hardship was more strongly associated with current depression than with prior history of depression. The relative effect of hardship was strongest in late adulthood but the absolute effect of hardship was greatest in middle age. CONCLUSIONS: The results demonstrate the critical role of financial hardship in the association between socio-economic disadvantage and 12-month depressive episode, and suggest that social and economic policies that address inequalities in living standards may be an appropriate way to reduce the burden attributable to depression.

Poor mental health influences risk and duration of unemployment: a prospective study.

PURPOSE: The current paper aims to investigate the role of mental health in determining future employment status. Much of the previous longitudinal and prospective research has focused on how unemployment adversely influences mental health, while the reverse causal direction has received much less attention. METHODS: This study uses five waves of data from 5,846 respondents in the HILDA survey, a nationally representative household panel survey conducted annually since 2001. Prospective analyses followed a group of respondents who were not unemployed at baseline across four subsequent years and investigated whether baseline mental health was associated with subsequent unemployment. RESULTS: Baseline mental health status was a significant predictor of overall time spent unemployed for both men and women. Decomposing this overall effect identified sex differences. For women but not men, baseline mental health was associated with risk of experiencing any subsequent unemployment whereas for men but not women mental health was associated with the duration of unemployment amongst those who experienced unemployment. CONCLUSIONS: By following a group of respondents who were not unemployed over time, we showed that poor mental health predicted subsequent unemployment. On average, men and women who experienced symptoms of common mental disorders spent greater time over the next 4 years unemployed than those with better mental health but there were sex differences in the nature of this effect. These findings highlight the importance of mental health in the design and delivery of employment and welfare policy.
