Association of Antenatal COVID-19-Related Stress with Postpartum Maternal Mental Health and Negative Affectivity in Infants

IMPORTANCE Antenatal stress is a significant risk factor for poor postpartum mental health. The association of pandemic-related stress with postpartum outcomes among mothers and infants is, however, less well understood. OBJECTIVE To examine the association of antenatal COVID-19-related stress with postpartum maternal mental health and infant outcomes. DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted among 318 participants in the COVID-19 Risks Across the Lifespan study, which took place in Australia, the UK, and the US. Eligible participants reported being pregnant at the first assessment wave between May 5 and September 30, 2020, and completed a follow-up assessment between October 28, 2021, and April 24, 2022. MAIN OUTCOMES AND MEASURES COVID-19-related stress was assessed with the Pandemic Anxiety Scale (score range, 0-4, with higher scores indicating greater COVID-19-related stress). The 8-item Patient Health Questionnaire (score range, 0-3, with higher scores indicating more frequent symptoms of depression) was used to measure maternal depression at each time point, and the 7-item General Anxiety Disorder scale (score range, 0-3, with higher scores indicating more frequent symptoms of anxiety) was used to measure generalized anxiety at each time point. At follow-up, postpartum distress was assessed with the 10-item Postpartum Distress Measure (score range, 0-3, with higher scores indicating greater postpartum distress), and infant outcomes (negative and positive affectivity and orienting behavior) were captured with the Infant Behavior Questionnaire (score range, 1-7, with higher scores indicating that the infant exhibited that affect/behavior more frequently). RESULTS The study included 318 women (mean [SD] age, 32.0 [4.6] years) from Australia (88 [28%]), the US (94 [30%]), and the UK (136 [43%]). Antenatal COVID-19-related stress was significantly associated with maternal postpartum distress (β = 0.40 [95%CI, 0.28-0.53]), depression (β = 0.32 [95%CI, 0.23-0.41]), and generalized anxiety (β = 0.35 [95%CI, 0.26-0.44]), as well as infant negative affectivity (β = 0.45 [95%CI, 0.14-0.76]). The findings remained consistent across a range of sensitivity analyses. CONCLUSIONS AND RELEVANCE The findings of this cohort study suggest that targeting pandemic-related stressors in the antenatal period may improve maternal and infant outcomes. Pregnant individuals should be classified as a vulnerable group during pandemics and should be considered a public health priority, not only in terms of physical health but also mental health

A detailed hierarchical model of psychopathology: From individual symptoms up to the general factor of psychopathology

Much of the knowledge about the relationships among domains of psychopathology is built on the diagnostic categories described in the Diagnostic and Statistical Manual of Mental Disorders (DSM), and relatively little research has examined the symptom-level structure of psychopathology. The aim of this study was to delineate a detailed hierarchical model of psychopathology—from individual symptoms up to a general factor of psychopathology—allowing both higher- and lower-order dimensions to depart from the structure of the DSM. We explored the hierarchical structure of hundreds of symptoms spanning 18 DSM disorders in two large samples—one from the general population in Australia (n = 3,175) and the other a treatment-seeking clinical sample from the United States (n = 1,775). There was marked convergence between the two samples, offering new perspectives on higher-order dimensions of psychopathology. We also found several noteworthy departures from the structure of the DSM in the symptom-level data.R. F.

The CLIMATE schools combined study: a cluster randomised controlled trial of a universal Internet-based prevention program for youth substance misuse, depression and anxiety

Background: Anxiety, depressive and substance use disorders account for three quarters of the disability attributed to mental disorders and frequently co-occur. While programs for the prevention and reduction of symptoms associated with (i) substance use and (ii) mental health disorders exist, research is yet to determine if a combined approach is more effective. This paper describes the study protocol of a cluster randomised controlled trial to evaluate the effectiveness of the CLIMATE Schools Combined intervention, a universal approach to preventing substance use and mental health problems among adolescents. Methods/design: Participants will consist of approximately 8400 students aged 13 to 14-years-old from 84 secondary schools in New South Wales, Western Australia and Queensland, Australia. The schools will be cluster randomised to one of four groups; (i) CLIMATE Schools Combined intervention; (ii) CLIMATE Schools - Substance Use; (iii) CLIMATE Schools - Mental Health, or (iv) Control (Health and Physical Education as usual). The primary outcomes of the trial will be the uptake and harmful use of alcohol and other drugs, mental health symptomatology and anxiety, depression and substance use knowledge. Secondary outcomes include substance use related harms, self-efficacy to resist peer pressure, general disability, and truancy. The link between personality and substance use will also be examined.Discussion: Compared to students who receive the universal CLIMATE Schools - Substance Use, or CLIMATE Schools - Mental Health or the Control condition (who received usual Health and Physical Education), we expect students who receive the CLIMATE Schools Combined intervention to show greater delays to the initiation of substance use, reductions in substance use and mental health symptoms, and increased substance use and mental health knowledge

Changes over time in young adults' harmful alcohol consumption: A cross-temporal meta-analysis using the AUDIT

Background: Recent studies suggest that young adult participation in, and volume of, alcohol consumption has decreased. However, the evidence on trends in harmful alcohol consumption in this age group is limited. The current paper aims to examine changes over time in harmful alcohol consumption using a robust, widely employed measure. Methods: The literature was systematically searched for articles reporting on Alcohol Use Disorders Identification Test (AUDIT) scores in young adults aged 18-24 years. The key data extracted were year of measurement and mean AUDIT score (proportion above clinical cut-off was not relevant for these analyses). Cross-temporal meta-analysis was applied to the extracted data. Results: A decrease was found in young adults’ AUDIT scores measured between 1989 and 2015 (b=-0.13, β=-0.38, p=0.015, 95% CI=-0.24, -0.03), representing a 0.63 standard deviation change over this period. Variance did not change over this time, suggesting scores decreased equally over the distribution. Conclusions: Results indicate that harmful alcohol consumption in young adults may have declined between 1989 and 2015. Despite the continued problems posed by dependence and short and long-term harms, these promising findings offer hope that the considerable alcohol-related disease burden in this age group may be reduced.Ongoing data collection is required to evaluate whether these declines in young adulthood persist into later life, and future research should explore the reasons for declining harmful alcohol consumption in young adults

Effectiveness of transdiagnostic Internet cognitive behavioural treatment for mixed anxiety and depression in primary care

BACKGROUND: Internet-delivered cognitive behavioural treatment (iCBT) has been shown to be effective for the combined treatment of depression and anxiety in randomised controlled trials. The degree to which these findings generalise to patients in primary care awaits further investigation. METHODS: Using an open-trial design, we investigated adherence to, and effectiveness of a 6-lesson therapist-assisted iCBT program for mixed anxiety and depression for patients (n = 707) who completed the program under the supervision of primary care clinicians (general practitioners, psychologists and other allied health professionals). Primary outcome measures were the PHQ-9 (depression), GAD-7 (generalised anxiety), K-10 (distress), WHODAS-II (disability), mini-SPIN (social anxiety) and panic disorder severity scale self-report version (PDSS). RESULTS: Adherence to the iCBT program was modest (47.3%), but within-subjects effect sizes ranged from medium (0.51 for PDSS) to large (1.20 for PHQ-9). LIMITATIONS: The lack of control group, limited post-treatment data due to drop-out, and short follow-up period. CONCLUSIONS: iCBT is an effective treatment for mixed depression and anxiety when delivered in primary care settings. Methods to increase adherence are needed to optimise the benefits to patients
