Validity of the 12-item version of the General Health Questionnaire in detecting depression in the general population

Longitudinal trajectories and associated risk factors of paternal mental illness in the nine years surrounding the transition to fatherhood

BACKGROUND

The arrival of one's first child is a known risk factor for mental illness, yet investigations on fathers' mental health are limited. We conducted a longitudinal investigation on paternal depression and anxiety in the nine years surrounding the transition to fatherhood.

METHODS

Using a national cohort of French men (CONSTANCES, n = 6299), we investigated the prevalence and associated risk factors of mental illness amongst first-time fathers. Responses to the Center for Epidemiological Studies Depression (CES-D) and 12-item General Health Questionnaire (GHQ-12) scales were used to identify clinically significant symptom scores. Self-declared mental illness was also reported by participants. Group-based modelling was used to identify latent trajectory groups for both measures.

RESULTS

Levels of self-declared anxiety (averaging 4.9 % pre-fatherhood, 7.8 % post) exceeded that of depression (1.9 % pre- fatherhood, 3.3 % post) or other disorders. However, rates of clinically significant symptom scores (17-27 %) were consistently higher. Participants' mental health appeared to worsen from two-years prior to their child's arrival and improve from two-years after. We identified three trajectory groups for fathers' self-declared mental illness: Low stable (90.3 %); Low risk with high temporary increase (5.6 %); and Consistent high risk (4.1 %). Risk factors associated with worsening mental health trajectories were unemployment, not living with one's partner, having had adverse childhood experiences and foregoing healthcare due to financial reasons.

LIMITATIONS

All measures of mental illness relied on participant self-reports and are thus subject to bias.

CONCLUSIONS

This study reveals an important period of heightened psychological vulnerability amongst first-time fathers, emphasising the need for increased and better adapted paternal mental health screening.

Screening depression among university students utilizing GHQ-12 and machine learning

The escalating incidence of depression has brought attention to the increasing concern regarding the mental well-being of university students in the current academic environment. Given the increasing mental health challenges faced by students, there is a critical need for efficient, scalable, and accurate screening methods. This study aims to address the issue by using the General Health Questionnaire-12 (GHQ-12), a well recognized tool for evaluating psychological discomfort, in combination with machine learning (ML) techniques. Firstly, for effective screening of depression, a comprehensive questionnaire has been created with the help of an expert psychiatrist. The questionnaire includes the GHQ-12, socio-demographic, and job and career-related inquiries. A total of 804 responses has been collected from various public and private universities across Bangladesh. The data has been then analyzed and preprocessed. It has been found that around 60% of the study population are suffering from depression. Lastly, 16 different ML models, including both traditional algorithms and ensemble methods has been applied to examine the data to identify trends and predictors of depression in this demographic. The models' performance has been rigorously evaluated in order to ascertain their effectiveness in precisely identifying individuals who are at risk. Among the ML models, Extremely Randomized Tree (ET) has achieved the highest accuracy of 90.26%, showcasing its classification effectiveness. A thorough investigation of the performance of the models compared, therefore clarifying their possible relevance in the early detection of depression among university students, has been presented in this paper. The findings shed light on the complex interplay among socio-demographic variables, stressors associated with one's profession, and mental well-being, which offer an original viewpoint on utilizing ML in psychological research.

Measuring psychological distress using the 12-item general health questionnaire and the six-item Kessler psychological distress scale. Psychometric comparison and equipercentile equating of the two scales

OBJECTIVES

This study aimed to examine if the General Health Questionnaire (GHQ)-12 and Kessler 6 (K6) assess the same underlying construct and to develop a score conversion table for the two scales.

METHODS

A random sample of 4303 people who completed both the GHQ-12 and K6 in 2021 were analyzed. Exploratory bifactor analysis evaluated if both scales measured the same construct, and Rasch analysis assessed item severities. The scales were transformed using Equipercentile equivalence for comparability and score conversion. Agreement was estimated with Cohen's Kappa coefficient, along with raw positive and negative agreement.

RESULTS

We found that the two scales measure the same phenomenon to the extent that they can be made equivalent. Conversion tables between GHQ-12 and K6 are presented. Applying the commonly used cut-off of ≥3 on the GHQ-12 bi-modal scoring, we found that the best corresponding cut-off on the K6 would be ≥8. The prevalence of psychological distress was then 22% with GHQ-12% and 21% with K6.

CONCLUSIONS

The GHQ-12 and K6 measure the same construct and corresponding cut-off scores on one scale were found for the other scale. This is valuable for longitudinal studies or time series where one scale has replaced the other scale.

Long-term trends in mental health disparities across sexual orientations in the UK: a longitudinal analysis (2010-2021)

BACKGROUNDS

In the context of increasing hate crimes, legislative challenges, and anti-LGBTQ + sentiment, we conducted the first study that comprehensively examined long-term mental health disparities across sexual orientations in the UK from 2010 to 2021. Prior studies predominantly relied on cross-sectional or limited longitudinal designs, thus failing to capture evolving trends over a decade and providing crucial insights into the dynamics of mental health challenges faced by sexual minorities, essential for devising targeted public health interventions and policies.

METHODS

Waves 2-12 of the UK Longitudinal Household Survey for adults (n = 52,591) were used. MCS-12 (Mental Health Component Scale of the Short-Form Health Survey) for mental functioning and GHQ (General Health Questionnaire) for psychological distress were included as the main outcomes, along with other measures of well-being. Mixed-effect longitudinal models were used to examine the trends of mental health disparities across sexual orientations.

RESULTS

Relative to their heterosexual counterparts, psychological distress (GHQ) increased for gay men, lesbians, and women with "other" orientations. Bisexual women saw the steepest increase from 1.69 higher GHQ vs. their heterosexual counterparts in 2010 (95%CI: 0.81 to 2.57), up to 3.37 in 2021 (95%CI: 2.28 to 4.45). Similar trends were also shown in the other measures.

CONCLUSIONS

The study highlights increases in mental health disparities between sexual minorities and heterosexuals. The escalating psychological distress among sexual minorities, particularly bisexual women, calls for an urgent, multi-faceted, and intersectoral response. This approach must address both symptoms and the social structures perpetuating these disparities across sexual orientations.

Ethnic Density and Mental Health: Does it Matter Whether the Ethnic Density is Co-ethnic or Multi-ethnic and How Important is Change in Ethnic Density?

The ethnic density thesis suggests a protective health benefit for ethnic minorities living in places with higher concentration of co-ethnic residents. This paper aims to make a step change in the examination of this thesis by proposing ethnic diversity rather than co-ethnic density will be more protective for mental health. The paper proposes ethnic diversity could be a community asset that benefits the health of all people in a neighbourhood regardless of their own ethnic group. Individual data is taken from the UK Household Longitudinal Study, 2009-2019 linked to aggregate data from the 2001 and 2011 Censuses to test the association between co-ethnic density, ethnic diversity and mental health using the General Health Questionnaire 12-item scale. The paper takes a novel approach by measuring pre-existing (in 2001) and change in (2001-2011) co-ethnic density and ethnic diversity. Moderating effects of individual ethnic group, neighbourhood deprivation and perceived social cohesion are tested. Results show lower pre-existing co-ethnic density is related to lower mental health amongst the White British ethnic group but not in most ethnic minority groups. Greater pre-existing ethnic diversity in more deprived neighbourhoods is associated with better mental health regardless of individual ethnic group. A point of contention in the findings is no association between change in ethnic diversity and mental health.

Factors associated with substance use among preclinical medical students in Turkey: a cross-sectional study

Introduction

Medical students experience high levels of stress due to their rigorous training, which can negatively affect their mental health. This study aimed to investigate substance use habits of medical students at Istanbul University-Cerrahpaşa and the association on their mental health and demographic factors.

Methods

This cross-sectional survey study was conducted in March-April 2022 among preclinical medical students (years 1-3 of a 6-year program). A confidential, anonymous online survey consisting of four sections on sociodemographic and educational characteristics, nicotine use and dependence [Fagerström Test for Nicotine Dependence (FTND)], alcohol use [Alcohol Use Disorders Identification Test (AUDIT)], mental health status [12-item General Health Questionnaire (GHQ-12)], was distributed to 1131 students via WhatsApp and Telegram text messages. Mann-Whitney U and Kruskal Wallis tests compared variables' distribution in the questionnaire categories. Spearman's correlation assessed associations between scales. Significance was p < 0.05.

Results

The study included 190 medical students. A total of 26.3% of the participants were smokers, with 8.4% showing moderate to high levels of nicotine dependence. An estimated 45.8% and 8.4%reported low-risk consumption and risky usage of alcohol, respectively. There were statistically significant associations between substance use and demographic factors such as sex, GPA, and religious belief. The study found a statistically significant correlation between FTND scores and GHQ-12 scores, and, between FTND scores and AUDIT scores.

Conclusion

The findings of this study will inform the development of interventions to improve the mental health and academic performance of medical students at Istanbul University-Cerrahpaşa. Furthermore, it will raise awareness about the importance of addressing substance use among medical students in Turkey.

Comparative Effectiveness of Supine Avoidance versus Continuous Positive Airway Pressure for Treating Supine-isolated Sleep Apnea: A Clinical Trial

Rationale: About 20-35% of patients with obstructive sleep apnea (OSA) have supine-isolated OSA, for which supine sleep avoidance could be an effective therapy. However, traditional supine discomfort-based methods show poor tolerance and compliance to treatment and so cannot be recommended. Supine alarm devices show promise, but evidence to support favorable adherence to treatment and effectiveness at reducing excessive daytime sleepiness compared with continuous positive airway pressure (CPAP) remains limited. Objectives: To establish if alarm-based supine-avoidance treatment in patients with supine-isolated OSA is noninferior to CPAP in reducing daytime sleepiness. Methods: After baseline questionnaire administration and in-home supine-time and polysomnography assessments, patients with supine-isolated OSA and Epworth Sleepiness Scale scores ⩾8 were randomized to ⩾6 weeks of supine-avoidance or CPAP treatment, followed by crossover to the remaining treatment with repeat assessments. Noninferiority was assessed from change in Epworth Sleepiness Scale with supine avoidance compared with CPAP using a prespecified noninferiority margin of 1.5. Average nightly treatment use over all nights and treatment efficacy and effectiveness at reducing respiratory disturbances were also compared between treatments. Results: The reduction in sleepiness score with supine avoidance (mean [95% confidence interval], -1.9 [-2.8 to -1.0]) was noninferior to that with CPAP (-2.4 [-3.3 to -1.4]) (supine avoidance-CPAP difference, -0.4 [-1.3 to 0.6]), and the lower confidence limit did not cross the noninferiority margin of 1.5 (P = 0.021). Average treatment use was higher with supine avoidance compared with CPAP (mean ± standard deviation, 5.7 ± 2.4 vs. 3.9 ± 2.7 h/night; P < 0.001). Conclusions: In patients with supine-isolated OSA, vibrotactile supine alarm device therapy is noninferior to CPAP for reducing sleepiness and shows superior treatment adherence.

The association between higher education attendance and common mental health problems among young people in England: evidence from two population-based cohorts

BACKGROUND

It is unclear whether young people who attend higher education are at increased risk of common mental disorders, compared with those who do not attend. We aimed to investigate whether higher education attendance was associated with increased symptoms of common mental disorders (depression and anxiety) in young people before, during and after attendance.

METHODS

For this cohort study, we used two cohorts-the Longitudinal Studies of Young People in England (LSYPE1: N=4832, 55·8% [2696 of 4832] students; LSYPE2: n=6128, 50·7% [3104 of 6128] students), beginning in 2004 for LSYPE1 and 2013 for LSYPE2. Both cohorts were designed to be nationally representative, with schools in England as the primary sampling unit. Symptoms of common mental disorders were assessed with the General Health Questionnaire (GHQ-12) before (age 14-17 years for both cohorts), during (age 18-19 years for LSYPE2), and after (age 25 years for LSYPE1) higher education. We assessed differences in GHQ scores using unadjusted and confounder adjusted linear regression.

FINDINGS

At ages 18-19 years (LSYPE2), mean GHQ-12 scores were 12·0 (SD 6·4) among students and 11·6 (SD 6·8) among non-students (adjusted mean difference 0·36, 95% CI 0·05 to 0·68; p=0·024). In LSYPE1, young people who attended higher education at ages 18-20 years had higher symptoms of common mental disorders at ages 16-17 years than those who did not (0·60, 0·30 to 0·90). However, after higher education (age 25 years for LSYPE1), there was no evidence of a difference-mean GHQ-12 scores were 11·4 (SD 5·5) among those who had attended and 11·7 (SD 6·4) among those who had not attended (-0·25, -0·66 to 0·16; p=0·23).

INTERPRETATION

We found evidence that students had more symptoms of common mental disorders than non-students at ages 18-19 years, albeit the effect size was small and there was no evidence of a longer-term difference at the age of 25 years.

A Mental Health Pandemic? Assessing the Impact of COVID-19 on Young People's Mental Health

BACKGROUND

Research indicates that young people have been a particularly vulnerable group when it comes to negative mental health outcomes following COVID-19, with some authors warning of a 'mental health pandemic'.

MATERIALS AND METHOD

Using a survey approach, this study explored the effects of lockdowns on the mental health of 1995 16-year-olds in Northern Ireland. Respondents completed the 12-item version of the General Health Questionnaire (GHQ-12) along with closed- and open-ended questions about COVID-19.

RESULTS

Results from regression analysis showed that being female, identifying as non-heterosexual and perceiving that mental health had worsened during lockdown were the best predictors of poor mental health. In the open responses, young people reported significant concerns about their mental health and their educational outcomes. They also felt that their needs were not given the same priority as those of adults during lockdown.

CONCLUSIONS

The results suggest that the COVID-19 lockdowns adversely affected the mental health of many young people in Northern Ireland with the effects most acute for females and those identifying as non-heterosexual. Future research should explore the longer-term impact of the pandemic on the mental health of these vulnerable young people and identify what support mechanisms need to be put in place to mitigate the negative effects of any future crises.

Defining the Characteristics of an e-Health Tool for Suicide Primary Prevention in the General Population: The StopBlues Case in France

With over one million deaths per year in the world, suicide is a major public health problem that could be significantly reduced by effective prevention programs. E-health tools are of particular interest for primary prevention as they can address a broad population including people unaware of their own risk and provide information and help without the fear of stigma. Our main objective was to define the overall characteristics of an e-health tool for suicide primary prevention in the French general population by defining the characteristics of the IT features; the content of the information delivered; the best way to structure it; and how it should be relayed and by whom. The research was carried out through a literature review and a co-construction phase with stakeholders. Four types of strategies may guide the construction of e-health tools for suicide primary prevention: education and awareness, (self-)screening, accessing support, and mental health coping. They should be accessible on different devices to reach the most users, and language and content should be adapted to the target population and to the issue being addressed. Finally, the tool should be consistent with ethical and quality best practices. The e-health tool StopBlues was developed following those recommendations.

The influence of perceived stress and income on mental health in China and Germany

Background

Mental health issues affect rich and poor, young and old, and are widespread in Asia as well as in Europe. However, few studies have investigated the influence of perceived stress and income on mental health among general population in China and in Germany.

Methods

We conducted an online survey from December 2021 to February 2022 to investigate how perceived stress and income affect mental health among the general population in China (N = 1123) and in Germany (N = 1018). Accordingly, we used the 10-item Perceived Stress Scale (PSS-10) and the 12-item General Health Questionnaire (GHQ-12). We ran a multiple linear regression model to investigate the relationship between perceived stress, income, and mental health.

Results

Overall, we found that 53.4% participants reported mental health issues (GHQ-12 score ≥12). The proportion of our sample who reported mental health issues was higher in Germany (60.3%) than in China (44.8%). The regression model revealed that a higher perceived stress score was associated with more mental health issues in both countries (b = 0.60, p < 0.01). Individuals with a low income reported poorer mental health in Germany than those in China. Interestingly, the situation was reversed when incomes were high: individuals with a high income reported worse mental health in China than in Germany (b = -0.40, p < 0.01).

Conclusion

Perceived stress has a negative impact on mental health, while income has differential effects. Mental health promotion programmes may involve teaching stress management, while considering differences in mental health outcomes in developed and developing countries.

Association between low internal health locus of control, psychological distress and insulin resistance. An exploratory study

AIM

To assess the hypothesis that low internal health locus of control (IHLC) and psychological distress (PD) are associated with insulin resistance.

MATERIALS AND METHODS

In 2002-2005, a random population sample of 2,816 men and women aged 30-74 years participated (76%) in two municipalities in southwestern Sweden. This study included 2,439 participants without previously known diabetes or cardiovascular disease. IHLC was measured by a global scale and PD was measured by the 12-item General Health Questionnaire. Insulin resistance was estimated using HOMA-ir. General linear models were used to estimate differences in HOMA-ir between groups with low IHLC, PD, and both low IHLC and PD, respectively.

RESULTS

Five per cent (n = 138) had both PD and low IHLC, 62 per cent of participants (n = 1509) had neither low IHLC nor PD, 18 per cent (n = 432) had PD, and 15 per cent (n = 360) low IHLC. Participants with both low IHLC and PD had significantly higher HOMA-ir than participants with neither low IHLC nor PD (Δ = 24.8%, 95%CI: 12.0-38.9), also in the fully adjusted model (Δ = 11.8%, 95%CI: 1.5-23.0). Participants with PD had significantly higher HOMA-ir (Δ = 12%, 95%CI: 5.7-18.7), but the significance was lost when BMI was included in the model (Δ = 5.3%, 95%CI:0.0-10.8). Similarly, participants with low IHLC had significantly higher HOMA-ir (Δ = 10.1%, 95%CI: 3.5-17.0) but the significance was lost in the fully adjusted model (Δ = 3.5%, 95%CI: -1.9-9.3).

CONCLUSIONS

Internal health locus of control (IHLC) and psychological distress (PD) were associated with insulin resistance. Especially individuals with both PD and low IHLC may need special attention.

The negative impact of loneliness and perceived stress on mental health during two-month lockdown in Shanghai

BACKGROUND

Shanghai undergone COVID-19 lockdown for 2 months in 2022, affecting >25 million population. We aim to find changes in mental health during Shanghai lockdown and if mental health was associated with Shanghai lockdown, loneliness, and perceived stress.

METHODS

We conducted two cross-sectional online surveys in China, which were before and at the end of Shanghai lockdown (survey 1 in January 2022, N = 1123; survey 2 in June 2022, N = 2139). Participants reported mental health, loneliness, and perceived stress through the 12-item General Health Questionnaire (GHQ-12), the short-form UCLA Loneliness Scale (ULS-8), and the 10-item Perceived Stress Scale (PSS-10). We compared data between survey 1 and 2. We ran a multiple linear regression model to investigate the impact of Shanghai lockdown, loneliness and perceived stress on mental health.

RESULTS

There's an increase in the proportion of lonely people during Shanghai lockdown (49.77 % to 65.26 %). During Shanghai lockdown, the proportion of lonely people (68.97 % VS. 61.35 %, p < 0.001) and risk for mental health conditions (50.50 % VS. 43.27 %, p < 0.001) were higher among residents in Shanghai than outside Shanghai. Shanghai lockdown (b = 0.556, p = 0.02), higher ULS-8 (b = 0.284, p < 0.001) and higher PSS-10 (b = 0.365, p < 0.001) were associated with higher GHQ-12.

LIMITATIONS

Participants reported their mental health status during Shanghai lockdown retrospectively.

CONCLUSION

Shanghai lockdown had psychological impacts not only on residents in Shanghai but also outside Shanghai. Addressing loneliness and perceived stress accommodated to the lockdown situation should be considered.

On cloud nine? Maternal emotional wellbeing six weeks up to one year postpartum - A cross-sectional study

BACKGROUND

Little is known about the full scope of emotional wellbeing of mothers up to one year postpartum, to adequately support women during transition to motherhood. Reduced emotional wellbeing (REW) affects women's adaption to the changes and challenges in becoming a mother. We aimed to increase the knowledge and understanding of mothers' emotional wellbeing and the influencing factors.

METHODS

This cross-sectional study includes 385 Flemish mothers up to one year postpartum. Online data were collected with the General Health Questionnaire-12, Postpartum Bonding Questionnaire, Personal Well-Being Index-Adult, The Basic Psychological Needs Scale, Sense of Coherence-13 and Coping Operations Preference Enquiry.

RESULTS

A total of 63.9% of the participants reported REW. Mothers with REW more often had (a history of) psychological problems compared to mothers with healthy emotional wellbeing (p = 0.007). Multiple linear regression analysis showed negative associations between emotional wellbeing and satisfaction (p = 0.002; p < 0.001), comprehensibility (p = 0.013) and positive associations between emotional wellbeing and bonding (p < 0.001), manageability (p = 0.033), problem solving (p = 0.030) and avoidance (p = 0,011) - with an explained variance of 55.5%.

LIMITATIONS

Some limitations of our study are the GHQ-12 cut-off value, the nature and implication of (a history of) psychological problems and the self-selected population.

CONCLUSION

It would be of worth for midwives to discuss with mothers (to be) what to expect. This - to support mothers in making sense of their life as a mother and how various factors might influence their emotional wellbeing. The high prevalence of REW is worrying, but needs to be interpreted with caution.

Are actual and perceived environmental conditions associated with variation in mental health?

OBJECTIVE

Empirical evidence on the relationship between environmental factors and mental health remains inconclusive. One reason is that there is only scant evidence on the association between mental health and subjective exposure to environmental stressors, relative to objective pollution. We thus focus on how the perceived and actual presence of noise, air pollution, and green spaces relates to mental health.

METHODS AND RESULTS

Our cross-sectional study is based on a large representative sample of the adult population in Switzerland (n = 5729). Using individual-level geocodes of subjects' residence, we combined data from a survey of these individuals with data on objectively measured longer-term environmental conditions (noise, air pollution, green spaces). Subclinical mental health was assessed with the 12-item General Health Questionnaire (GHQ-12). When fitting multiple regressions and mediation models, we find that perceptions of environmental stressors are a better predictor of mental distress than objectively measured stressors. In addition, the predictive power of actual nature visits is stronger than the predictive power of mere proximity to green spaces at the place of residence. We found no direct link between actual environmental stressors and mental health, but mediation via perceived environmental stressors. Further, the association between the frequency of nature visits and mental health is mediated by perceived, but not actual pollution.

CONCLUSION

Since actual environmental stressors are not perceived as equally burdensome by all people, their subjective perception is crucial when evaluating policy interventions aimed at improving mental health. Even a relatively low level of environmental stressors, classified as non-harmful to human health in a physical or biological sense, may thus contribute to negative mental health outcomes. The main policy implication is that attractive and accessible green spaces may provide individuals with an enhanced sense of control over their exposure to environmental stressors and thereby reduce negative impacts.

Associations between transient and chronic loneliness, and depression, in the understanding society study

OBJECTIVES

Loneliness has a long-established link with depression; however, patterns of loneliness, specifically transient (short-term) and chronic loneliness (longer-term), have seldom been researched in terms of their associations with depression and psychiatric distress. We investigated whether chronic loneliness could predict higher levels of psychiatric distress and higher chance of depression diagnosis (via self-report) than transient and no loneliness.

METHODS

We used data from 18,999 participants in Waves 9 and 10 of the Understanding Society survey: a nationally representative study of adults in the United Kingdom. The study used a between-subjects, cross-sectional, design, where participants' scores on loneliness measures across two time points were combined to form patterns of loneliness, and participants were compared on their levels of psychiatric distress and depression diagnoses across the three loneliness groups: chronic loneliness (lonely at both time points), transient loneliness (lonely at one time point) and no loneliness.

RESULTS

Regression analyses revealed that patterns of loneliness predicted both the likelihood of participants reporting a history of depression diagnosis and participants' levels of psychiatric distress. The chronic loneliness group had the highest likelihood of self-reported depression diagnosis and had the highest levels of psychiatric distress, compared to both the transient and no loneliness groups. Transient loneliness, in turn, predicted higher likelihood of reporting a history of depression diagnosis and higher levels of psychiatric distress than the no loneliness group.

CONCLUSIONS

The study replicates and extends prior findings, suggesting that prolonged loneliness even over the course of one year is a risk factor for poorer mental health.

An Item-Response Mapping from General Health Questionnaire Responses to EQ-5D-3L Using a General Population Sample from England

BACKGROUND

The 12-item General Health Questionnaire (GHQ-12) is widely used to measure mental health and well-being; however, it is not possible to estimate values on the full health = 1, dead = 0 scale used to construct quality-adjusted life-years (QALYs) from GHQ-12 responses as it is not preference-based.

OBJECTIVE

The aim of this study was to create an item-response mapping between GHQ-12 and EQ-5D-3L health states, for which several value sets exist.

METHODS

Data from the 2012 Health Survey for England with complete GHQ-12 and EQ-5D-3L descriptive system responses were used for analysis. Data were split 70/30 into estimation/test samples. Four modelling approaches, with EQ-5D-3L levels on each dimension as dependent variables and GHQ-12 responses as independent variables were assessed: non-parametric, simple ordered logit (OL), extended OL, and least absolute shrinkage and selection operator (LASSO). Approaches were assessed using Akaike and Bayesian information criteria, predictive accuracy measured using root mean squared error (RMSE), and simplicity.

RESULTS

A total of 8114 responses became 6924 after discarding missing values, with 4847 used in estimation and 2077 used for testing. LASSO had a better model fit on the pain/discomfort dimension, but no model had markedly superior predictive accuracy. The non-parametric approach was chosen for the mapping algorithm based on simplicity. Predicted and observed EQ-5D-3L values for the test sample had a correlation of 0.488. Prediction accuracy was better for GHQ-12 scores below 20 than scores above 20.

CONCLUSION

The mapping allows EQ-5D-3L responses to be predicted using GHQ-12 responses, which may be useful in estimating utility values and QALYs. An R script and Microsoft Excel spreadsheet are provided to facilitate calculations.

Prevalence of probable eating disorders and associated risk factors: An analysis of the Northern Ireland Youth Wellbeing Survey using the SCOFF

OBJECTIVES

Eating disorders (ED) are associated with significant morbidity and mortality rates and are most common in young people aged between 15 and 19 years. Large representative surveys on disordered eating in youth are lacking. The main aims were to estimate the prevalence of disordered eating in a representative sample of 11-19 year olds in Northern Ireland and investigate the associations between probable eating disorder and a range of risk factors.

DESIGNS AND METHODS

A large nationally representative household survey was conducted, and the bivariate and multivariate associations between demographic, familial, economic and psychological risk factors and probable eating disorder were assessed.

RESULTS

A total of 16.2% (n = 211) of the sample met the SCOFF screening criteria for disordered eating. Probable eating disorder was associated with being female (OR = 2.44), having a parent with mental health problems (OR = 1.68), suffering from certain psychological problems, such as mood or anxiety disorder (OR = 2.55), social media disorder (OR = 2.95), being the victim of physical bullying (OR = 1.71) and having smoked (OR = 2.46).

CONCLUSIONS

This study provides the first prevalence estimates of probable eating disorder among youth in Northern Ireland. Furthermore, the study identifies unique risk factors for probable eating disorder among this representative sample.

Prevalence and predictors of psychological distress before, during, and after a COVID-19 pandemic wave in Switzerland, 2021

There are concerns about acute and long-term mental health effects of the COVID-19 pandemic. This study examined the prevalence and predictors of psychological distress before, during, and after a pandemic wave in Switzerland, 2021. Prevalence of psychological distress was estimated in adults aged 35-96 years using the General Health Questionnaire-12 administered in June 2021 (Specchio-COVID19 cohort, N = 3965), and compared to values from 2003 to 2006 (CoLaus|PsyCoLaus cohort, N = 5667). Anxiety and depression were assessed from February to June 2021 using the Generalised Anxiety Disorder scale-2 and the Patient Health Questionnaire-2, respectively. Prevalence of psychological distress in June 2021, after the pandemic wave (16.0% [95% CI, 14.6%-17.4%]) was comparable to pre-pandemic levels (15.1% [14.0%-16.2%]). Anxiety and depression were highest at the start of the pandemic wave in February 2021, and declined from February to June with the relaxation of measures. Predictors of psychological distress included being younger, female, a single parent, unemployed, a change in working hours or job loss in the past 6 months, greater perceived severity and contagiousness of COVID-19, and self-reported post COVID-19. By June 2021, following a pandemic wave, prevalence of psychological distress in Switzerland was closer to pre-pandemic levels. These findings highlight the need for additional mental health support during times of stricter government policies relating to COVID-19; yet they also suggest that individuals can adapt relatively quickly to the changing context.

Psychometric evaluation of the Swedish Multidimensional Psychological Flexibility Inventory (MPFI)

Psychiatric disorders are common, and reliable measures are crucial for research and clinical practice. A cross-diagnostic construct that can be used to index treatment outcomes as well as prevalence of psychological ill health is psychological flexibility. The aim of this study was to validate a Swedish version of the Multidimensional Psychological Flexibility Inventory (MPFI). The MPFI has 12 subscales, six of which measure flexibility, and six that measure inflexibility. Using confirmatory factor analysis in a community sample of 670 participants, we found that a model with two higher order factors had satisfactory fit (CFI = .933) and a 12-factor model had the best fit to the data (CFI = .955). All 12 subscales showed adequate reliability (CRs = .803-.933) and the factor structure was similar across age groups and gender. Findings suggest that the Swedish version of the MPFI is a reliable instrument that can be used to index psychological flexibility. Potential areas for improvement of the instrument are discussed.

Selling one's future: over-indebtedness and the risk of poor mental health and the role of precarious employment - results from the Scania Public Health Cohort, Sweden

OBJECTIVES

The credit market has expanded rapidly, increasing the risk of over-indebtedness among those who lack secure employment or adequate income, an issue of concern in the COVID-19 aftermath. We investigated the role of over-indebtedness for developing poor mental health, and whether this impact is modified by age, gender, educational level or being in precarious employment.

METHODS

This is a cohort study using data from the Swedish Scania Public Health Cohort, based on individuals randomly selected from the general adult population in Scania, southern Sweden, initiated in 1999/2000 (response rate 58%) with follow-ups in 2005 and 2010. Over-indebtedness was assessed by combining information on cash margin and difficulty in paying household bills. Mental health was assessed by General Health Questionnaire-12. Those with poor mental health at baseline were excluded, and the analyses were further restricted to vocationally active individuals with complete data on main variables, resulting in 1256 men and 1539 women.

RESULTS

Over-indebtedness was more common among women, among persons with a low educational level, born abroad and with a precarious employment at baseline. The age-adjusted incidence rate ratio (IRR) for poor mental health in 2010 among individuals exposed to over-indebtedness in 1999/2000 or 2005 was 2.2 (95% CI 1.7 to 2.8). Adjusting for educational level, country of origin and precarious employment in 1999/2000 or 2005, yielded an IRR of 2.0 (95% CI 1.6 to 2.6). An interaction analysis indicated that a high level of education may act synergistically with over-indebtedness, regarding poor mental health among men.

CONCLUSIONS

Over-indebtedness was related to unfavourable societal power relations, regarding social class, gender and foreign birth. Precarious employment was independently linked to poor mental health and may also mediate the effect by over-indebtedness. The COVID-19 pandemic might entail increased over-indebtedness, which should be acknowledged in policies aiming at buffering social effects of the pandemic.

Are We All the Same When Faced with an Ill Relative? A Person-Oriented Approach to Caring Activities and Mental Health in Emerging Adult Students

Dealing with the illness/disability of a relative is part of everyday life for many students, who may have to take on caring responsibilities. Fulfilling a caring role during emerging adulthood has been associated with poorer mental health. This study adopts a person-oriented approach in exploring the caring experience in relation to mental health. The sample comprised 3273 students (Mage = 20.19 years, SDage = 1.89; 80.35% female) who answered a series of questionnaires. A cluster analysis identified six patterns of caregiving activities in terms of their nature and extent: few caring activities; household chores; household and financial/practical help; emotional care; sibling care; and many caring activities with emotional and personal care. A series of analyses showed that caring activities differed according to age, gender, living arrangements, financial status, the ill/disabled relative being supported, and the relative's type of illness/disability. A multivariate analysis of covariance showed that emerging adult students with patterns featuring household chores had better mental health than those with few caring activities. Overall, our findings indicate that having an ill/disabled relative can lead an individual to take on a wide range of caring responsibilities that may have varying consequences for emerging adult students' mental health.

Trajectories of housing affordability and mental health problems: a population-based cohort study

PURPOSE

With housing costs increasing faster than incomes and a limited supply of social housing options, many households face unaffordable housing. Housing affordability problems may negatively impact mental health; however, longitudinal evidence is limited. This study investigates the association between trajectories of housing affordability problems and mental health.

METHODS

We used data from 30,025 households from Understanding Society, a longitudinal household survey from the UK. Participants spending 30% or more of household income on housing were categorised as facing housing affordability problems. We estimated group-based trajectories of housing affordability problems from 9 waves of data (2009-2019). We used linear regression to calculate the association between the trajectories and mental health problems, as measured by General Health Questionnaire (GHQ) score in Wave 10 (2018-2020).

RESULTS

We found six distinct trajectories of housing affordability problems. Those in the 'stable low' group had a consistently low probability of affordability problems, whilst those in 'high falling' group had a sustained high probability in the earlier waves of the study, subsequently decreasing over time. The adjusted analysis showed that trajectory group membership over the first nine waves of data predicted GHQ score in 2018-2020 (Wave 10). Compared to the 'stable low' group, those in the 'high falling' group had a GHQ score that was 1.06 (95% CI 0.53-1.58) points higher.

CONCLUSION

This study provides evidence that sustained exposure to housing affordability problems is associated with long-term worse mental health, even in the absence of more recent problems.

What are the mental health consequences of austerity measures in public housing? A quasi-experimental study

BACKGROUND

As governments around the world implement austerity measures to reduce national deficits, there is an urgent need to investigate potential health impacts of specific measures to avoid unintended consequences. In 2013, the UK government implemented the underoccupancy penalty (ie, the bedroom tax) to reduce the national housing benefits bill, by cutting social housing subsidies for households deemed to have excess rooms. We investigated the impact of the bedroom tax on self-reported psychological distress.

METHODS

Using data from the UK Household Longitudinal Study (2010-2014), the sample included those who received housing subsidies, aged 16-60, living in England. Control and treatment groupings were identified on their household composition and housing situation. We used matching methods to create an exchangeable set of observations. Difference-in-differences analysis was performed to examine changes across the prereform and postreform psychological distress of the treatment and control groups, using the 12-item General Health Questionnaire.

RESULTS

The implementation of the reform was associated with a moderate increase in psychological distress (0.88, 95% CI 0.06 to 1.71) among the treatment group, relative to the control group. However, the announcement was not associated with change in psychological distress (0.53, 95% CI 0.21 to 1.27).

CONCLUSION

Our study provides evidence that the implementation of housing austerity measures can increase psychological distress among social housing tenants. As the use of austerity measures become more widespread, policy-makers should consider supplementary interventions to ameliorate potential negative health consequences.

Joint association of socioeconomic circumstances and minor mental health problems with antidepressant medication

Background

Disadvantageous socioeconomic circumstances and minor mental health problems have both been associated with mental disorders, such as depression, but their joint contribution remains unknown.

Methods

The Helsinki Health Study baseline survey (2000–02) of 40- to 60-year-old employees was linked with antidepressant medication data from registers of the Social Insurance Institution of Finland. The analyses were made using logistic regression with first prescribed antidepressant medication purchase during a 10-year follow-up as the outcome. Minor mental health problems were measured by the emotional well-being scale of the RAND-36. Odds ratios were calculated for joint association of the lowest quartile of the emotional well-being scale of the RAND-36 and socioeconomic circumstances. Childhood (parental education and childhood economic difficulties), conventional (education, occupational class and income) and material (housing tenure and current economic difficulties) socioeconomic circumstances were examined. This study included 5450 participants.

Results

Minor mental health problems dominated the joint associations. Minor mental health problems were associated with antidepressant medication irrespective of socioeconomic circumstances whereas only low income, current economic difficulties and living in rented housing showed an association without minor mental health problems at baseline. Marital status, working conditions and BMI and health behaviours had only minimal contributions to the associations.

Conclusions

Minor mental health problems were consistently and strongly associated with antidepressant medication and dominated the joint associations with socioeconomic circumstances. Paying attention to minor mental health problems might help prevent mental disorders such as depression.

Social integration of people with non-psychotic mental illness over the last 2 decades: the widening gap in the adult population in Belgium

PURPOSE

Social integration is poor among people with mental illness (MI). In recent decades, many countries have developed policies to address this issue. It remains unclear, however, whether their social integration has improved over time. This study aimed to assess the evolution of the social integration of adults with moderate and severe non-psychotic MI compared to the general population without MI between 1997 and 2018 in Belgium.

METHODS

Data on the general adult population were retrieved from the Belgian Health Interview Survey in six cross-sectional waves from 1997 to 2018. Three degrees of non-psychotic MI severity were compared using the 12-items General Health Questionnaire: no MI, moderate MI, and severe MI (score < 4, 4-7, and > 7). Social integration was measured using indicators relating to employment, income, social contacts, and partnership.

RESULTS

Since 1997, the probability of being unemployed, having limited social contacts, and living on less than 60% of the median national income has been increasing among people with severe non-psychotic MI. Between 1997 and 2018, social integration increased among the general population without MI and among people with moderate non-psychotic MI, but decreased among people with severe non-psychotic MI.

CONCLUSION

The gap between the social integration of people with severe non-psychotic MI and people with moderate or no MI has widened over time, despite major reforms of mental health care and policies. Policymakers and clinical practitioners should pay more attention to supporting the social integration of people with more severe MI, particularly in relation to employability and social support.

Psychological distress in Spanish airline pilots during the aviation crisis caused by the COVID-19 pandemic and psychometric analysis of the 12-item general health questionnaire

The aim of this study was to evaluate the psychological distress of Spanish airline pilots, a group of professionals undergoing an unprecedented work situation as a result of the Covid-19 pandemic. To do so, we administered the General Health Questionnaire-12 (GHQ-12). A total of 342 questionnaires were obtained, with the largest respondent age group being 41-50 years. The psychometric properties of the instrument were also evaluated, with an exploratory factor analysis revealing a unidimensional structure that explained 59.23% of the variance. The total score on the standard GHQ-12 was 4.54 ± 3.31 very close to the cut-off point established to determine psychological distress. The score increased among those unemployed and was also higher among pilots on furlough compared to those whose work situation was relatively normal. Furthermore, the reliability measured by the total Cronbach's alpha was above 0.8 of each across all employment status considered. These results show the desirability of conducting periodic psychological distress assessments of pilots so that effective measures can be implemented to ensure their psychological and socio-emotional well-being. Practitioner summary: This article evaluates psychological distress in a group of professionals that has received scant attention in the field. Moreover, it does so against the background of an atypical situation, evaluating the psychological distress suffered by pilots in different employment categories during the current severe crisis in the aviation sector.Abbreviations: CFI: comparative fit index; COPAC: Official College of Commercial Aviation Pilots; ECA: European Cockpit Association; EFA: exploratory factor analysis; GHQ-12: general health questionnaire-12; IATA: International Air Transport Association; KMO: Kaiser-Meyer-Olkin test; PA: optimal implementation of parallel analysis; ULS: unweighted least squares.

A workplace Acceptance and Commitment Therapy (ACT) intervention for improving healthcare staff psychological distress: A randomised controlled trial

The levels of psychological distress and burnout among healthcare staff are high, with negative implications for patient care. A growing body of evidence indicates that workplace programmes based on Acceptance and Commitment Therapy (ACT) are effective for improving employees' general psychological health. However, there is a paucity of research examining the specific psychological and/or behavioural processes through which workplace ACT programmes transmit their beneficial effects. The aim of this randomised controlled trial was to investigate the outcomes and putative processes of change in a 4-session ACT training programme designed to reduce psychological distress among healthcare staff (n = 98). Ninety-eight employees of a healthcare organisation were randomly allocated to the ACT intervention or to a waiting list control group. Study measures were administered on four occasions (baseline, mid-intervention, post-intervention, and follow-up) over a three-month evaluation period. Results showed that the ACT intervention led to a significant decrease in symptoms of psychological distress and a less pronounced reduction in burnout. These effects were mediated primarily via an improvement in mindfulness skills and values-based behaviour and moderated by participants' initial levels of distress. At four-week post-intervention, 48% of participants who received the ACT intervention showed reliable improvements in psychological distress, with just under half of the aforementioned improvements (46.15%) meeting criteria for clinically significant change. The results advance ACT as an effective stress management intervention for healthcare staff. The findings should be confirmed in a large scale randomised controlled trial with longer follow-up and cost-effectiveness analyses.

Successful implementation of parenting support at preschool: An evaluation of Triple P in Sweden

Although emotional and behavioural problems among young children are common and, if unaddressed, can lead to multi-facetted problems later in life, there is little research investigating the implementation of parenting programs that target these problems. In this study, the RE-AIM framework was used to evaluate the implementation of the Triple P parenting program in a preschool setting at a medium-sized municipality in Sweden. Reach increased over time, showing an overall increase in participating fathers and parents with lower education. Effectiveness outcomes showed an improvement in emotional and behavioural problems in children and less mental health-related symptoms and higher self-efficacy in parents. Adoption rate was 93.3%. To ensure staff “buy-in”, designated coordinators made changes in recruitment procedures, and provided supervision and training to all Triple P practitioners. Implementation adaptations were made, such as minor revisions of parenting strategies and other program content, as well as providing child care during seminars and groups, and setting up weekend-groups. Maintenance assessed through 12 month follow-up data suggested that several child and parent outcomes were maintained over time. Uppsala municipality continues to offer Triple P to parents. The reach, effectiveness, adoption, implementation and maintenance of the program were all satisfactory and demonstrated the suitability of delivering evidence-based parenting support using preschools as an arena.

Cost-Effectiveness of an Online Intervention for Caregivers of People Living With Dementia

OBJECTIVES

Little evidence exists on costs or cost-effectiveness of online interventions for caregivers of people living with dementia. We aimed to assess cost-effectiveness of online cognitive behavioral therapy (CBT) for dementia caregivers with mild-to-moderate depression/anxiety, with or without telephone support, relative to a psychoeducational control treatment.

DESIGN

Cost-effectiveness study of data from 3-armed randomized controlled trial comparing computerized CBT (cCBT) or telephone-supported cCBT (cCBT+Telephone) to modular online educational program on dementia (Psychoeducation).

SETTING AND PARTICIPANTS

UK-resident adult dementia caregivers with mild-to-moderate anxiety/depression.

COST-EFFECTIVENESS ANALYSIS

We calculated health and social care costs, from participant-reported data collected at baseline, 12, 26 weeks, costs of intervention delivery. We examined 3 outcomes: cost of one-point reduction in General Health Questionnaire-12 (GHQ-12) rating at 26-weeks, cost of prevented "caseness" on GHQ-12 at 26 weeks, and cost per quality-adjusted life year (QALY) based on Short Form-6 Dimensions (SF-6D) over 26 weeks.

RESULTS

Data from 176 participants (44 cCBT, 91 cCBT+Telephone, 41 Psychoeducation) were analyzed. Costs did not differ between cCBT and Psychoeducation; costs were £125 higher in cCBT+Telephone. Control and intervention groups did not differ on GHQ-12. Caseness was lower in cCBT+Telephone than Psychoeducation; cost of preventing a case was £610, and probability of cost-effectiveness on this outcome reached 98.5% at willingness to pay (WTP) of £12,900. Mean QALY did not differ between cCBT+Telephone and Psychoeducation. QALY gain in cCBT was 0.01 (95% CI 0.001, 0.021). Cost per QALY was £8130. Although base case probability of cost-effectiveness of cCBT was 93% at WTP-per-QALY of £27,600, sensitivity analyses suggested cCBT+Telephone was the more cost-effective.

CONCLUSIONS AND IMPLICATIONS

We report preliminary evidence for adopting telephone-supported online CBT. This may be cost-effective in preventing a case of mental health disorder if, absent a societally accepted WTP threshold for this outcome, payers are willing to pay £12,900. Future research should investigate whether supported/unsupported online CBT improves health-related quality of life.

Does the longitudinal association between neighbourhood cohesion and mental health differ by ethnicity? Results from the UK Household Longitudinal Survey

PURPOSE

While the association between neighbourhood cohesion and mental health has been widely studied in the general population, the effects of neighbourhood cohesion across ethnic groups are not well understood. Ethnicity is often left out of study design, many studies do not consider effect modification by ethnicity, or they rely on overly simplistic ethnic categories.

METHODS

Data from the UK household longitudinal study were used to investigate whether changes in neighbourhood cohesion are independently associated with changes in mental health (measured using the GHQ) over 9 years (2009-2018), and whether the association differed across 17 ethnic groups. The study used a fixed-effect modeling approach that includes within-person estimators that allow each participant to act as their own control.

RESULTS

Compared to British White, the following ethnic groups all saw a similar improvement in GHQ (- 0.76, 95% CI - 0.83 to - 0.70) for each point increase in neighbourhood cohesion: Irish, any other White, White and Asian mixed, Chinese, Caribbean, African, any other Black, Arab, and others. Some ethnic groups saw stronger improvements in mental for each point increase in neighbourhood cohesion, including White and Black Caribbean mixed, any other mixed, Indian, Pakistani, any other Asian, with the strongest effect seen in Bangladeshi participants (- 2.52. 95% CI - 3.48 to - 1.56).

CONCLUSION

Our study highlights the importance of ethnocultural data in research examining neighbourhood effects on mental health. Future research should evaluate policies to improve neighbourhood cohesion for ethnic minorities to address ethnic mental health disparities.

Associations between Adolescent Psychosocial Factors and Disengagement from Education and Employment in Young Adulthood among Individuals with Common Mental Health Problems

Transition to adulthood can be a challenging developmental task for adolescents with common mental health problems and is linked to adverse outcomes such as ‘not in education, employment or training’ (NEET). This study investigated longitudinal associations between adolescent psychosocial factors (e.g., self-esteem, aspirations, bullying, physical activity) and later NEET status among individuals with common mental health problems (i.e., depression and anxiety). A secondary data analysis of the Next Steps cohort study was completed using waves 2 and 8. Psychosocial factors, mental health, and background characteristics were captured when participants were aged 15–16 years (wave 2) while still in compulsory education. The 12-item General Health Questionnaire was used to identify adolescents with common mental health problems. The study population consisted of 2224 participants (females 66.8%) of which 1473 (66.2%) were aged 15 years and 751 (33.8%) were aged 16 years in wave 2. The outcome was NEET status at ages 25–26 years (wave 8). The results showed that after adjusting for background characteristics, adolescent self-esteem, locus of control, bullying, physical activity, job aspirations, and attitudes to school predicted NEET status. Educational aspirations, substance use, and behavioural problems were not significantly associated with NEET status. These findings provide new insights into the role of adolescent psychosocial factors in the context of education and employment outcomes for youth at risk and highlight the necessity of targeted mental health support to improve life chances.

The mental health impact of multiple deprivations under protracted conflict: A multi-level study in the occupied Palestinian territory

Building on the literatures examining the impacts of deprivation and war and conflict on mental health, in this study, we investigate the impact of different forms of deprivation on mental health within a context of prolonged conflict in the occupied Palestinian territory(oPt). We expand the operationalization go deprivation while accounting for more acute exposures to conflict and political violence and spatial variations. We use multilevel modelling of data from the Socio-Economic & Food Security Survey 2014 conducted by the Palestinian Central Bureau of Statistics, which included a sample size of 7827 households in the West Bank(WB) and Gaza Strip(GS). We conduct the analysis for the combined sample, as for the WB and GS separately. We use a General Health Questionnaire-12 (GHQ12) score as our main outcome measure of poor health. We used various measures of deprivation including subjective deprivation, material deprivation, food deprivation, and political deprivation. In addition to the different measures of deprivation, we included acute political, health, and economic shocks in our analysis along with background socio-demographic characteristics. The results indicate significant variance at the locality level. We find a significant association between poor mental health and subjective, economic, political, and food deprivation; health, economic, and political stressors; age, and being a woman. Post-secondary education and wealth have a significant inverse association with poor mental health. Subjective deprivation is the strongest predictor of GHQ12 score in the models whereby people who feel very deprived have GHQ12 scores that are almost 4-points higher than people who do not feel deprived. Economic conditions, particularly subjective measures, are significant predictors of mental health status. Our findings confirm that political and social factors are determinants of health. Feeling deprived is an important determinant of mental health. The community effect suggests that spatial characteristics are influencing mental health, and warrant further investigation.

The association between effort-reward imbalance, work-life balance and depressive mood in Korean wage workers: The 4th Korean Working Conditions Survey

Background

This study was conducted to determine the association between work-life (WL) balance, effort-reward (ER) imbalance, and depressive mood in Korean wage workers when 2 models were considered simultaneously.

Methods

We analyzed 26,014 Korean workers including 13,471 men and 12,543 women from the 4th Korean Working Conditions Survey data. Multiple logistic regression was used to analyze the association between WL, ER status, and the depressive mood of Korean workers. We classified the subjects into a total of 4 groups as follows. Group 1: WL and ER status are both “balanced”, group 2: WL status is “imbalanced” and ER status is “balanced”, group 3: WL status is “balanced” and the ER status is “imbalanced”, group 4: WL and ER status are both “imbalanced.”

Results

We found significantly increased odds ratios (ORs) for depressive mood in groups 2, 3, and 4 compared with group 1 after adjusting for the general and occupational characteristics of the subjects in both men and women. We also found that the trend of ORs increased gradually from groups 2 to 4 compared with group 1 in both men and women; group 2: OR: 1.23 (95% confidence interval [CI]: 1.12–1.35), group 3: OR: 1.40 (95% CI: 1.27–1.55), group 4: OR: 1.99 (95% CI: 1.74–2.28) compared with group 1 in men; group 2: OR: 1.28 (95% CI: 1.15–1.42), group 3: OR: 1.45 (95% CI: 1.31–1.59), group 4: OR: 2.04 (95% CI: 1.76–2.36) compared with group 1 in women.

Conclusions

As a result, we found the association between imbalanced WL, ER status, and depressive mood in Korean workers using 2 models simultaneously. It is important to provide a balanced WL and ER condition to improve the mental health of workers.

Impaired Quality of Life in Patients with Autoimmune Atrophic Gastritis

BACKGROUND

Autoimmune atrophic gastritis (AAG) leads to vitamin B12 deficiency that may manifest with neuropsychiatric disorders, such as emotional instability, cognitive deficits, depression, and personality changes.

AIMS

To evaluate the quality of life (QoL) in patients with AAG and the interplay between QoL, psychopathological symptoms, and demographic factors.

METHODS

This is an observational, cross-sectional study including 102 patients with AAG (mean age 62 ± 13 years), 100 with functional gastrointestinal disorders (mean age 38.3 ± 17 years), 100 with other chronic organic gastrointestinal diseases (mean age 50.9 ± 21.4 years), and 100 healthy controls (mean age 37.5 ± 18.9 years). The 36-Item Short Form Health Survey questionnaire (SF-36) and the General Health Questionnaire-12 were administered. The results of the scales were compared among the study groups. Linear regression analyses were fitted to identify independent predictors of QoL in AAG patients.

RESULTS

QoL was significantly different among the four groups in all subdomains. In particular, the AAG group was significantly (P < 0.01) more impaired than the functional gastrointestinal disorder group in the physical functioning and it was significantly more impaired than the control group in all the quality of life subdomains with exception of vitality. Vitamin B12 serum level was a significant (P < 0.04) independent predictor of physical functioning.

CONCLUSIONS

Patients with AAG have a decreased QoL compared to healthy controls, but in line with that of patients with organic gastrointestinal disorders. Physical component is responsible for worsening QoL. Vitamin B12 supplementation may positively affect patient's perception of body functioning.

Prevention of sick leave at the workplace: design of a cluster-randomized controlled trial of a problem-solving intervention among employees with common mental disorders

Background

Common mental disorders are highly prevalent in the working population, affecting about 1 in 5 persons in the Organisation for Economic Co-operation and Development countries. About 30% of those affected have a first period of sick leave. Despite several attempts to reduce the risk of sick leave among employees with common mental disorders, there is a lack of knowledge about effective, preventive interventions which aim to reduce such risks. This protocol describes the design of a study to evaluate the effectiveness of a problem-solving intervention delivered by first-line managers to employees with common mental disorders on the prevention of sick leave during the 12-month follow-up.

Methods/design

The study applies a two-armed cluster-randomized trial design of a problem-solving intervention conducted in private-sector companies. First-line managers are randomized into intervention- or control groups by computer-generated random numbers, allocation ratio 1:1. Employees are eligible if at risk for future sick leave due to common mental disorders. These are identified by self-reported psychological health measured by the General Health Questionnaire 12-item, cut-off ≥3, or a positive answer to risk of sick leave.

The intervention is based on problem-solving principles. It involves the training of the first-line managers who then deliver the intervention to employees identified at risk of sick leave. First-line managers in the control group receives a lecture. Primary outcome is number of registered days of sick leave due to common mental disorders during the 12-month follow-up. Secondary outcomes are general health, psychological symptoms, work performance, work ability and psychosocial work environment. A process evaluation will examine the intervention’s reach, fidelity, dose delivered, dose received, satisfaction and context. Research assistants managing the screening procedure, outcome assessors and employees are blinded to randomization and allocation.

Discussion

The study includes analyses of the intervention’s effectiveness and an alongside process evaluation. Methodological strengths and limitations, for example the risk of selection bias, attrition and risk of contamination are discussed.

Allostatic load and mental health during COVID-19: The moderating role of neuroticism

Background

During the COVID-19 pandemic increased risk of poor mental health has been evident across different cultures and contexts. This study aims to examine whether allostatic load (AL) prior to the pandemic was predictive of poor mental health during the pandemic, and if any associations were moderated by neuroticism.

Methods

Data were extracted from Waves 2 (2011, allostatic load), 3 (2012, neuroticism), and the COVID-19 study (April 2020) of the Understanding Society database in the UK; data were available for 956 participants.

Results

Mental health increased from 2012- to during the pandemic. Neuroticism and AL were positively associated with poorer mental health during COVID-19, such that those who had scored higher on neuroticism and had higher AL prior to the pandemic reported poorer mental health during the pandemic. Neuroticism was also a significant moderator; the effect of AL on mental health during the pandemic was exacerbated in those with high and moderate levels of neuroticism but not lower. Moreover, this was driven by the immune-related indices of AL. This withstood adjustment for age, gender, employment status and prior mental health. These findings are discussed in relation to the pathophysiological mechanisms of mental health.

Urban Nature and Public Health: How Nature Exposure and Sociocultural Background Relate to Depression Risk

As the world’s population becomes more urbanized, there is an associated decrease in nature exposure and a rise in noncommunicable diseases, including depression. Previous cross-sectional studies examining urban nature exposure and depression have reported favorable associations. However, many of these studies rely primarily on nature exposure metrics that measure the intensity of nature exposure, while other dimensions of urban nature exposure remain understudied. Therefore, in a cross-sectional, questionnaire-based case study targeting a general urban population (n = 282), we examined the relationship between two less commonly studied urban nature exposure variables (i.e., gardening behavior and greenspace visit frequency) and depression risk while also considering sociocultural background (multivariate logistic regression model). Results indicated that being a gardener was significantly associated with a reduced odds of being at risk of depression and that having a family migration history, but not a self-migration history, was associated with increased odds of being at risk of depression. In the examination of neighborhood socialization frequency and depression risk, we did not determine any significant association. The results of this study, therefore, highlight the importance of considering both people’s sociocultural backgrounds and urban nature exposure in more detail to help plan for and support healthier cities in the future.

Coffee consumption and psychological wellbeing among Japanese auto factory workers

BACKGROUND:

Health habits are sometimes closely related to physical and mental health status.

OBJECTIVE:

The relationship between coffee consumption and psychological wellbeing was evaluated by considering confounding factors.

METHODS:

A total of 5,256 men, aged 35 to 60 years, from a workplace in Japan participated in this study conducted in 2018. Psychological wellbeing was evaluated using the General Health Questionnaire (GHQ) 12-item version and multivariate logistic regression analysis was used for the analysis.

RESULTS:

Positive GHQ12 score was significantly associated with average daily sleeping time < 4 h, lack of regular exercise and younger age. In contrast, there was no significant association between positive GHQ12 score and coffee consumption. Coffee consumption and smoking status was not significantly related to psychological wellbeing as measured using the GHQ questionnaire. In contrast, aging, regular exercise and sleeping time were related to psychological wellbeing.

CONCLUSION:

Coffee consumption was not significantly related to psychological wellbeing, and casual association might be confirmed by a prospective study.

Comorbid mental health issues in patients with pemphigus vulgaris and pemphigus foliaceus

The term 'pemphigus' refers to chronic autoimmune skin disorders that cause blistering erosions on the skin and oral mucosa. The two major clinical forms are pemphigus vulgaris and pemphigus foliaceus. Although rare, they confer a stark symptomatic burden upon patients that significantly impacts daily life. Comorbid mental health issues are not routinely screened for in patients with pemphigus, and current UK guidance provides no formal provision for the identification and treatment of psychological issues. This review is the first of its kind, to our knowledge, to systematically examine the available evidence on mental health issues in pemphigus. Published work suggests that the incidence of anxiety and depression is much higher in patients with pemphigus compared with both the general population and with patients having other chronic skin disorders. Disease severity appears to be closely linked to mental health, with worsening of pemphigus associated with deteriorations in psychological wellbeing. Corticosteroids, which are associated with depression in chronic use, are the current first-line therapy for pemphigus and have been identified as a potential confounder and independent risk factor for mental health comorbidity in pemphigus. Current evidence is unclear whether a bidirectional relationship exists between mental health and pemphigus severity, and more thorough research is required to develop understanding of this issue. In conclusion, we have identified a high incidence of mental health comorbidity in pemphigus, and recommend routine screening of patients with pemphigus for mental health issues and signposting toward mental health services as an initial measure to address this.

Work ability and psychological distress in a working population: results from the Stockholm Public Health Cohort

AIMS

Psychological distress is a global public health concern with individual and societal implications causing work-related disability and loss of productivity. It is less known how much work ability contributes to the development of psychological distress. This study aimed to assess the association between self-perceived physical and mental work ability in relation to job demands, and the incidence of psychological distress in a Swedish working population.

METHODS

Data were obtained from three subsamples of the Stockholm Public Health Cohort with baseline in 2010 and follow-up in 2014, based on a working population in Stockholm County aged 18-60 years, with no or mild psychological distress at baseline (n=29,882). Self-perceived physical and mental work ability in relation to job demands were assessed at baseline with a subscale from the Work Ability Index. Study participants scoring 4 or more on the General Health Questionnaire 12 at follow-up were classified as having developed psychological distress during the study period. Poisson log linear regression was used to calculate crude and adjusted rate ratios with 95% confidence intervals.

RESULTS

At follow-up, 2543 participants (12%) had developed psychological distress. Reporting poor physical and/or poor mental work ability in relation to job demands at baseline was associated with an almost doubled rate ratio of psychological distress at follow-up, compared to reporting good work ability (rate ratio 1.8; 95% confidence interval 1.6-2.0).

CONCLUSIONS

Poor work ability is associated with a higher incidence of future psychological distress compared to good work ability.

Heterogeneity in the association between youth unemployment and mental health later in life: a quantile regression analysis of longitudinal data from English schoolchildren

OBJECTIVES

An association between youth unemployment and poorer mental health later in life has been found in several countries. Little is known about whether this association is consistent across individuals or differs in strength. We adopt a quantile regression approach to explore heterogeneity in the association between youth unemployment and later mental health along the mental health distribution.

DESIGN

Prospective longitudinal cohort of secondary schoolchildren in England followed from age 13/14 in 2004 to age 25 in 2015.

SETTING

England, UK.

PARTICIPANTS

7707 participants interviewed at age 25.Primary and secondary outcome measures12-Item General Health Questionnaire (GHQ) Likert score, a measure of minor psychiatric morbidity.

RESULTS

Youth unemployment was related to worse mental health at age 25. The association was several times stronger at deciles of GHQ representing the poorest levels of mental health. This association was only partly attenuated when adjusting for confounding variables and for current employment status. In fully adjusted models not including current employment status, marginal effects at the 50th percentile were 0.73 (95% CI -0.05 to 1.54, b=0.11) points, while marginal effects at the 90th percentile were 3.76 (95% CI 1.82 to 5.83; b=0.58) points. The results were robust to different combinations of control variables.

CONCLUSIONS

There is heterogeneity in the longitudinal association between youth unemployment and mental health, with associations more pronounced at higher levels of psychological ill health. Youth unemployment may signal clinically relevant future psychological problems among some individuals.

Intersectional inequalities in mental health across multiple dimensions of inequality in the Swedish adult population

Intersectionality has recently gained traction in health inequality research emphasizing multiple intersecting dimensions of inequality as opposed to the traditional unidimensional approaches. In this study inequalities in mental health were estimated across intersections of gender, income, education, occupation, country of birth, and sexual orientation. The outcomes and inequalities of intersectional strata were disentangled analogously to the possibilities described by intersectionality theory; as a result of either of the two inequality dimensions, as a result of the sum the dimensions, or as a unique outcome not equaling the sum. Furthermore the study examined the discriminatory accuracy of the six inequality dimensions as well as the intersectional space comprising 64 strata. The study population (N = 52,743) consists of a yearly random sample of the Swedish population 26-84 years between 2010 and 2015, from The Health on Equal Terms survey. Mental health was measured through a self-administered General Health Questionnaire (GHQ)-12, and sociodemographics through survey and linked register data. Intersectional inequalities in mental health were estimated for all pairwise combinations of inequality dimensions by joint inequalities, excess intersectional inequalities and referent inequalities. The findings of the study found that the sum of dimensions contributed to the overall (joint) inequality in mental health rather than a reinforced adverse effect of multiple disadvantages or the contribution by a single dimension. Nevertheless, the dimension of income was found to be the most important in terms of relative contribution. The discriminatory accuracy was low indicating that policy action targeting mental health should be universal rather than focusing on particular groups. The results highlight the unpredictable inequality patterns revealed by an intersectional approach, even for a single health outcome and within one country, and illustrate the need for empirical investigations into the actual population patterns in health that appear in the intersections of multiple disadvantages.

A distress-continuum, disorder-threshold model of depression: a mixed-methods, latent class analysis study of slum-dwelling young men in Bangladesh

BACKGROUND

Binary categorical approaches to diagnosing depression have been widely criticized due to clinical limitations and potential negative consequences. In place of such categorical models of depression, a 'staged model' has recently been proposed to classify populations into four tiers according to severity of symptoms: 'Wellness;' 'Distress;' 'Disorder;' and 'Refractory.' However, empirical approaches to deriving this model are limited, especially with populations in low- and middle-income countries.

METHODS

A mixed-methods study using latent class analysis (LCA) was conducted to empirically test non-binary models to determine the application of LCA to derive the 'staged model' of depression. The study population was 18 to 29-year-old men (n = 824) from an urban slum of Bangladesh, a low resource country in South Asia. Subsequently, qualitative interviews (n = 60) were conducted with members of each latent class to understand experiential differences among class members.

RESULTS

The LCA derived 3 latent classes: (1) Severely distressed (n = 211), (2) Distressed (n = 329), and (3) Wellness (n = 284). Across the classes, some symptoms followed a continuum of severity: 'levels of strain', 'difficulty making decisions', and 'inability to overcome difficulties.' However, more severe symptoms such as 'anhedonia', 'concentration issues', and 'inability to face problems' only emerged in the severely distressed class. Qualitatively, groups were distinguished by severity of tension, a local idiom of distress.

CONCLUSIONS

The results indicate that LCA can be a useful empirical tool to inform the 'staged model' of depression. In the findings, a subset of distress symptoms was continuously distributed, but other acute symptoms were only present in the class with the highest distress severity. This suggests a distress-continuum, disorder-threshold model of depression, wherein a constellation of impairing symptoms emerge together after exceeding a high level of distress, i.e., a tipping point of tension heralds a host of depression symptoms.

Effectiveness of parenting education for expectant primiparous women in Asia: a systematic review

OBJECTIVE

This review evaluated the effectiveness of antenatal parenting education versus usual care for maternal confidence, maternal depressive symptoms, and parenting stress among expectant primiparous women in Asia.

INTRODUCTION

Previous reviews on parenting education have mostly examined practices in non-Asian countries and found that no single parenting education program met the needs of all parents. Given that there may be some common characteristics in Asian cultures, such as grandparents' involvement with child care, this review focused on specific interventions in determining the effects of practices on particular outcomes in these populations, so that providers of antenatal education can tailor interventions that are more culturally appropriate for Asian women.

INCLUSION CRITERIA

Studies published in English or Japanese that included expectant primiparous women and couples in Asia who received antenatal parenting education were considered. The outcomes were maternal confidence, maternal depressive symptoms, and parenting stress.

METHODS

The authors searched for English-language articles up to February 2019 using MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, and PsycINFO. They also searched Ichushi-Web for Japanese articles. A gray literature search was conducted using Google Scholar and ProQuest Health and Medical Collection. Two independent reviewers selected studies, and a critical appraisal was undertaken using appropriate JBI tools. Data were presented in narrative form owing to the heterogeneity of the included studies.

RESULTS

Four studies involving 652 pregnant women were included: three were randomized controlled trials, and one was a quasi-experimental study. The studies were conducted in China, Hong Kong, and Taiwan, and included the following antenatal parenting education interventions: interpersonal, psychotherapy-oriented childbirth education; childbirth psychoeducation based on the concept of learned resourcefulness; and Internet newborn-care education based on self-efficacy theory. Overall, the methodological quality of the included studies was moderate. Meta-analysis was not possible owing to the heterogeneity, including small sample sizes and differences in intervention content, populations, and follow-up times. A subsequent narrative synthesis was undertaken for each outcome. Of three studies with maternal confidence as an outcome (n = 496), two showed significantly higher maternal confidence at six weeks' (P = 0.000, Cohen's d = 1.41) and three months' postpartum (P = 0.016, Cohen's d = 0.35) in the intervention groups; however, one study showed no significant group differences. Of three studies with maternal depressive symptoms as an outcome (n = 534), two found significantly fewer depressive symptoms at three months' (P = 0.018, Cohen's d = -0.34) and six months' postpartum (P = 0.005, Cohen's d = -0.42) in the intervention groups; however, one study revealed no significant group differences. Parenting stress was examined in one study (n = 156); it showed significantly lower parenting stress (P = 0.017, Cohen's d = 0.38) immediately after the intervention.

CONCLUSIONS

There is insufficient evidence to support the effectiveness of a specific type of antenatal parenting education for maternal confidence, maternal depressive symptoms, and parenting stress for expectant primiparous women in Asia. However, the findings suggest that specific theory-oriented antenatal parenting education is potentially effective for those women. Further high-quality studies are needed for antenatal parenting education among expectant primiparous women, especially in Asia.

An Assessment of the Psychometric Properties of the GHQ-12 in an English Population of Autistic Adults Without Learning Difficulties

Valid and reliable tools to measure mental health are a key requirement to developing a robust evidence base on mental health difficulties and autism. There are several reasons why mental health measures developed for the neurotypical population may not be valid and reliable when used with autistic adults. Using data collected from a national evaluation of community-based, specialist autism provision in England, this study assessed the psychometric properties of the General Health Questionnaire (GHQ-12) in a population of autistic adults without learning difficulties. We examined the measure’s acceptability, reliability and internal construct validity. The GHQ-12 was found to have good psychometric properties in this population. This provides first evidence that this measure can be used with autistic adults without LD.
