Tracking perceived stress, anxiety, and depression in daily life: a double-downward spiral process

IntroductionPrevious studies using retrospective questionnaires have suggested a complex relationship between perceived stress and related negative emotions and emphasized their importance in mental health. However, how daily perceived stress, anxiety, and depression interact dynamically in a natural context remains largely unexplored.MethodsThis study conducted a longitudinal survey that applied experience sampling methodology to data from 141 Chinese college students (58% women, mean age = 20.1 ± 1.63 years).ResultsThe hierarchical linear models confirmed that daily perceived stress and negative emotions (i.e., perceived depression and anxiety) could reciprocally reinforce one another with the characteristic dynamics of a cognitive–emotional downward spiral. Additionally, anxiety and depression could further circularly aggravate each other imminently. These two intertwined downward-spiral processes constitute a double-downward-spiral model.DiscussionThe findings contribute to a better understanding of the interactive mechanisms underlying perceived stress and its related negative emotions in everyday life and highlight the significance of early emotion regulation and stress relief in healthy people.

Postpartum people’s experiences of and responses to the COVID-19 pandemic during the first year of the pandemic: A descriptive qualitative study

Women’s Health, Volume 19, Issue , January-December 2023. Background:Most evidence on the impact of pandemic on perinatal population’s experiences has reported such effects in a portion of the pandemic.Objectives:The aim of this study was to understand the postpartum people’s experiences of and responses to the coronavirus disease 2019 pandemic during the first year and to identify their health care needs.Design:This is a descriptive qualitative study.Methods:This study was conducted in British Columbia, Canada, between March 2020 and April 2021. Participants (N = 268) were at 4 months postpartum and were recruited as part of the Pregnancy Specific Anxiety Tool study through prenatal care clinics and classes, community laboratory services and social media. Qualitative data were obtained using six online open-ended questions and were analysed using thematic analysis.Results:Findings were grouped under five central themes: protecting baby (with three categories including hypervigilance, constant decision-making to find balance and developmental issues); psychological adjustments (with three categories including coping, anxiety and grief); experience of isolation and lack/loss of support (with two categories including isolation and loss of expected support); unexpected interruptions and life events (with four categories including interrupted maternity leave, unexpected changes/life events, positive impacts and interruption in health care services); and perceived postpartum care needs (with five categories including in-person visits, allowing support persons, providing information/education/support groups, mental health and social support and pro-active check-ins).Conclusion:Several impacts of the pandemic persisted throughout the first year, particularly isolation and lack of support. These findings can inform responsive health care services to address the emerging needs of postpartum people throughout the pandemic.

[Correspondence] A fundamental change is needed for appraising placebo responses in psychiatry

In the Alpha-Stim Anxiety Insomnia and Depression cranial electrotherapy stimulation trial, Richard Morriss and colleagues reported no significant difference in their primary depression outcome between active and sham groups.1 Although not the headline of the article, 41% of recruited patients who received sham stimulation had remission of their depression. This remarkable result adds to the growing list of neurotechnology trials in psychiatry demonstrating very large responses in their placebo arms.

The fNIRS evaluation of frontal and temporal lobe cortical activation in Chinese first-episode medication-naïve and recurrent depression during a verbal fluency task

… Functional near-infrared spectroscopy (fNIRS) identifies neurophysiological differences between psychiatric disorders by assessing cortical hemodynamic function. Few trials have studied differences in brain functional activity between first-episode medication-naïve depression patients (FMD) and recurrent major depression (RMD). We aimed to determine the differences between FMD and RMD in oxygenated hemoglobin concentration ([oxy-Hb]), and to investigate the
