Perceived stress and depression among Chinese nurses: a cross-sectional mediation analysis of psychological flexibility and its components

BackgroundPerceived stress is a significant risk factor for depression among healthcare professionals. While this fundamental relationship is well-documented, the potential mediating mechanisms—specifically the role of psychological flexibility and its distinct components—in buffering the impact of perceived stress on depression within the nursing community remain poorly understood.MethodsThis cross-sectional study recruited 3,920 nurses from three tertiary Grade A public hospitals in Xi’an, China, using convenience sampling, of whom 3,611 were included in the final analysis. Data were collected online using the Chinese versions of Cohen’s Perceived Stress Scale and the Comprehensive Assessment of Acceptance and Commitment Therapy Processes, as well as the Patient Health Questionnaire-9. Pearson correlation analyzes and mediation analysis were conducted to examine the associations among perceived stress, psychological flexibility, and depression.ResultsDepression was positively correlated with perceived stress (r = 0.63, p < 0.01). Mediation analysis indicated that perceived stress was significantly associated with depression both directly (b = 0.47, 95% CI: 0.45 to 0.49) and indirectly via psychological flexibility (b = 0.12, 95% CI: 0.11 to 0.13) and its components, including acceptance and cognitive defusion (b = 0.14, 95% CI: 0.13 to 0.15), and values and committed action (b = 0.06, 95% CI: 0.04 to 0.08). The indirect association through mindfulness and self-as-context was not significant (b = 0.01, 95% CI: 0.00 to 0.02).ConclusionsPsychological flexibility and some of its components were involved in partial indirect associations between perceived stress and depression among Chinese nurses. These findings suggest that psychological flexibility may help understand how perceived stress is statistically associated with depression in this population. Given the cross-sectional design, however, the results should be interpreted as statistical associations rather than evidence of causal relationships.

Beyond empirically supported treatments: a new contextualized evidence framework for evidence based psychology

Over the past three decades, criteria for Empirically Supported Treatments (ESTs) have strengthened methodological rigor in psychotherapy research by prioritizing randomized controlled trials and systematic evidence synthesis. However, prevailing frameworks remain largely centered on efficacy under controlled conditions, offering limited operational guidance for integrating contextual factors that critically shape real-world effectiveness. We propose the Contextualized Empirically Supported Treatment Framework (C-EST), a normative and operational model that integrates certainty of evidence with structured appraisal of contextual domains essential for clinical decision-making, guideline development, and policy. Building on the Tolin criteria, GRADE, GRADE-CERQual, and the GRADE Evidence-to-Decision approach, C-EST embeds assessment of empirical certainty within five interconnected domains (1): empirical evidence (2), critical appraisal of the body of evidence, (3) functional and cultural impact, (4) contextual factors, including values, acceptability, feasibility, and equity, and (5) transparency and living evidence. Rather than relying on binary classifications (“supported” vs. “unsupported”), the framework enables nuanced judgments such as “supported with contextual concerns,” explicitly documenting boundaries of applicability. Using Cognitive Behavioral Therapy for depression and psychological interventions for postpartum depression as illustrative cases, we demonstrate how contextual appraisal refines, rather than weakens, established evidence classifications. By aligning internal validity with external, cultural, and equity relevance, C-EST transforms evidence evaluation from a static designation into a dynamic decision-support tool. Integrating contextual evidence is not an ethical add-on but a methodological imperative to ensure that psychological treatments are not only efficacious, but applicable, equitable, and responsive to diverse real-world mental health needs.

Non-invasive electrical stimulation for sleep disturbances in adults: protocol for an evidence−mapping umbrella review of systematic reviews and meta−analyses with subgroup analysis by intervention type and population

BackgroundSleep disturbances affect 10%–30% of adults worldwide. Non−invasive electrical stimulation (e.g., transcranial electrical stimulation) has emerged as a promising non−pharmacological intervention. Although numerous systematic reviews and meta−analyses have been published, they vary considerably in methodological quality, populations, intervention types, and conclusions. No umbrella review has yet synthesised the evidence across different modalities and populations. This evidence mapping umbrella review aims to systematically chart the existing systematic reviews, assess methodological quality, quantify overlap, and describe evidence patterns across diverse modalities and populations.MethodsFollowing JBI guidelines, we will search PubMed, Embase, Cochrane Database of Systematic Reviews, Web of Science, PsycINFO, and Scopus (inception to April 2026), restricted to English. Grey literature will be searched via PROSPERO, ClinicalTrials.gov, Google Scholar (first 200 records), and reference list screening (snowballing). We will include systematic reviews and meta−analyses of randomised controlled trials evaluating any non−invasive electrical stimulation for sleep outcomes. Two reviewers will independently screen, extract data, and assess methodological quality using AMSTAR 2. Primary study overlap will be quantified by the Corrected Covered Area. Where feasible, we will calculate 95% prediction intervals, perform Egger’s regression tests, and conduct excess significance tests using review-level summary estimates. Subgroup analyses will be stratified by intervention and population type. Sensitivity analyses will exclude: (1) reviews with critically low AMSTAR 2 ratings, (2) preprints, (3) reviews at high risk of reporting bias, and (4) studies where sleep is not the primary outcome. The primary outcome is subjective sleep quality; total sleep time is a key secondary outcome. Evidence will be graded using the Fusar−Poli classification, with GRADE for key outcomes.DiscussionThis umbrella review will provide the highest level of evidence synthesis, identifying modalities with more consistent or higher certainty evidence and highlighting areas where evidence remains uncertain. Limitations include restriction to English (which may disproportionately impact modalities such as TEAS), expected heterogeneity, and possible insufficient data for some subgroup analyses. All amendments have been documented in PROSPERO (CRD420261357590).Clinical Trial Registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD420261357590.

A bidirectional relationship between atrial fibrillation and depression: epidemiology, mechanisms, and clinical implications

Atrial fibrillation (AF) represents a common cardiac arrhythmia that carries substantial morbidity and mortality risks, whereas depression serves as a significant psychological factor affecting cardiovascular health. Recent findings underscore a reciprocal relationship between AF and depression, suggesting that depression may heighten the likelihood of developing AF, while AF may, in turn, worsen depressive symptoms. This review aims to provide a thorough examination of the epidemiological features that underpin this relationship, focusing on population-based research that clarifies prevalence rates and associated risk factors. Furthermore, it delves into the intricate biological and psychosocial mechanisms that connect these two conditions, which include dysregulation of the autonomic nervous system, inflammation, neurohormonal pathways, and behavioral influences. The clinical ramifications of this reciprocal association are also addressed, highlighting the necessity for integrated screening and management approaches to enhance patient outcomes. By consolidating existing research, this article seeks to enrich the understanding of the relationship between AF and depression, as well as to assist clinicians in optimizing therapeutic strategies tailored to address this dual burden.

Plasma microRNA signatures in drug-naïve Romanian adolescents with first-episode psychosis

Psychotic disorders are a group of severe psychiatric conditions with onset typically occurring in adolescence or early adulthood. Despite significant efforts to identify clinically useful candidates, no validated biomarkers for psychiatric disorders currently exist. The diagnosis of psychotic disorders is exclusively based on clinical assessment, significantly affected by individual differences and symptom overlap. Although circulating microRNAs (miRNAs) have emerged as potential peripheral biomarkers for early diagnosis and disease evolution, most studies concentrate on adult, medicated cohorts. Studies on miRNA profiles in drug-naïve adolescents with first-episode psychosis (FEP) are scarce. This study aims to identify the plasma miRNA profile in treatment-naïve Romanian adolescents with first-episode psychosis and to compare it with that of age- and sex-matched healthy controls. The plasma from 14 adolescents, seven drug-naïve FEP and seven and age-matched controls (CTRL) aged 15–18 years was collected. Psychiatric symptoms were assessed using PANSS, HAM-D, and YMRS scales. The levels of 179 miRNAs were assessed using qRT-PCR. A case-control analysis on miRNAs levels between FEP and CTRL was performed, as well as correlations with clinical measures. Twenty-one miRNAs showed significantly lower levels and two higher levels in FEP patients compared to controls. After adjustment for multiple comparisons, miR-125a-5p, miR-205-5p, miR-145-5p, miR-363-3p, and miR-23b-3p remained statistically significant (FDR<0.05). Notably, miR-125a-5p, miR-23b-3p, and miR-146a-5p levels negatively correlated with psychotic, depressive, and manic symptom severity, while miR-16-5p and miR-363-3p positively correlated with symptom scores. Comparison with previous studies indicated limited overlap, reflecting potential influences of age, treatment status, and genetic or environmental factors. This work demonstrates that Romanian treatment-naïve adolescents with first-episode psychosis had a unique circulating miRNA profile correlated with symptom severity, indicating their potential as early-stage biomarkers. The results underscore the necessity of accounting for age, treatment status, and environmental variables in the interpretation of miRNA modifications in psychotic illnesses.

Centering People, Centering Stories: Folklore as an Unlikely Ally in the OCD Misdiagnosis Crisis

By: Rebecca Bernstein, MA Folklore

The International OCD Foundation’s (IOCDF) recent landmark white paper reveals more than 80% of OCD cases in America remain undiagnosed (International OCD Foundation, 2025). Considering the size of this clinical challenge, it might seem odd to suggest that a small, humanities-based field like folklore— yes, folklore — has any role to play in the solution. As someone who studies OCD personal narratives (stories people tell about their lived experiences), my research suggests otherwise. In a situation that invokes the feeling of all-hands-on-deck, the tools and perspectives of this field may offer more benefit than we might initially give it credit for.

Folklore is the study of informal, creative communication. Dr. Lynn McNeill describes it as anything people “say, do, make, or believe” (McNeill, 2013). Folklore includes everything you’d think of (quilts, traditional music, fairy tales) and a lot of things you wouldn’t (occupational culture, gossip, internet memes.) We find examples of folklore everywhere. It’s in our holidays and our hobbies, our food and our fads, our jokes and our grieving. Folklorists study the infinite ways people express themselves in daily life. This, in turn, helps us better understand the cultural realities in which they live. And because what we “say, do, make, or believe” describes most of human behavior, the folkloric lens can be an indispensable one with which to investigate the world.

The benefit of studying how people express themselves is obvious when we recognize that in mental health, conversation and narrative are the primary tools we use to give and receive care. OCD isn’t just a diagnosis. It’s also a fundamentally creative experience. (Creative things don’t necessarily have to be beautiful, pleasing, or even wanted. They just have to be new and meaningful.) (Dictionary.com, 2023). Although ego-dystonic, extraordinary beliefs and elaborate rituals are hallmark features of OCD. When sufferers discuss their experiences, they are naturally inclined to do so through their own personal and cultural lenses. Therefore, descriptions of OCD vary infinitely. If the issue is our failure to recognize OCD when it presents itself, an approach designed to make sense of something as messy as human expression may offer insights that quantitative research methods still struggle to obtain.

How Folklorists Research

Just like in biomedical research, the research methods folklorists use matter. Our goal is to better understand people and their communities. That means we strategically build relationships, listen deeply, and intentionally embrace the complexity of those we talk to.

When I started researching OCD narratives, I wanted to know: What were the internal realities like for people who lived with this illness? What made their stories distinct? And how might those stories be connected? One of the biggest challenges I faced in my fieldwork was the potential for my participants to self-censor. As someone who also lives with OCD, I knew all too well the role shame and fear could play in the choice to fully share one’s reality with others. Using both field-tested approaches and my own lived knowledge, I conducted interviews with people with OCD, approaching them in a way I hoped would ease interviewees into difficult conversations:

  • I provided anonymity. I held all interviews on Zoom, where participants were free to keep their cameras off. I also assigned each one an alphanumeric signifier (A1, B2, etc.) in my writing.
  • I emphasized the importance of story. Although I asked specific questions, I also allowed participants to go off topic and engage in two-way conversation. The story was the point.
  • I used the “kitchen table” interview method. Based on the work of Carl Lindahl, this method tries to recreate the intimacy of two individuals talking around a kitchen table. It discourages framing the interviewer as an objective party, recognizes storytellers as experts in their own experiences, and suggests that interviewers only ask questions they themselves would be willing to answer (Lindahl, 2012).
  • I disclosed. My choice to openly discuss my own OCD diagnosis with interviewees allowed conversations to proceed with a certain warmth and vulnerability.
  • I emphasized participants’ humanity. I treated each participant as a full individual rather than just a source of information. This meant I worked on a model of enthusiastic consent. It also meant I asked them for feedback on my writing to ensure I portrayed their experiences accurately.
  • I compensated participants well. Each received a $100 gift card.

The Results

The universal theme I discovered during these interviews was a profound concern with social isolation. Every single participant mentioned this issue. Interviewees shared how OCD made it difficult for them to maintain relationships and how challenging it was to hide their illness from others. They also recalled their joy and gratitude when discussing moments in which they felt understood.

Their narratives also contained four other common themes:

1.) Logic and patterns of personal concern. Participants often discussed their particular obsessions and compulsions, and the influence those specific thoughts and behaviors had on their daily lives.

2.) Issues of negotiation. People talked about navigating certain types of conflicts as a result of their illness. These conflicts generally fell into two categories: self-negotiation and existential negotiation. In the first, people struggled with the desire to take their thoughts and urges seriously despite knowing they didn’t make sense. In the second, they wrestled with their relationships to the divine.

3.) Positive approaches to the illness. Many interviewees made a point to mention the silver linings they saw in being sick. They noted how OCD made them safer, more empathetic, or provided them with particular skills. Others discussed productive choices they’d made despite living with such a debilitating condition.

4.) Interactions with medical systems. Participants talked about their experiences as patients. For some, dealing with doctors, therapists, and other health professionals helped them understand their experience or relieved their suffering. For others, these encounters were confusing, unhelpful, or even traumatizing.

It’s important to note these themes represent a truly broad range of content. Not every story included every theme, and within those themes, the specific details I heard varied as much as the individuals themselves.

Implications

Say you were to hear four stories: one about someone’s preferred cleaning routine, one about someone’s waning belief in God, one about a good decision made in a difficult circumstance, and one about a doctor’s visit. It’s unlikely you’d consider these stories connected. And yet the data shows they are. The fact that stories with dramatically different content can reflect the same illness highlights the way OCD can remain elusive and camouflaged.

The problem with recognizing these stories as OCD stories isn’t just the variation in content. It’s also in how others hear them. In folklore, we don’t just study cultural expressions. We also study how they move from person to person. “Tellable narratives” travel easily. Both speakers and listeners understand what a certain type of story should sound like and the meaning it’s supposed to convey. If I tell you a tale about a persecuted young woman who escapes a bad home life and marries a prince, you can probably guess you’ve heard Cinderella. If we’re both excited that she went from rags to riches, we share an understanding that her journey is a positive one. In contrast, an “untellable narrative” hits some kind of barrier. If you’ve never heard Cinderella before or think the stepmother is actually the hero, my meaning in telling you the story gets lost. Untellable narratives can be misinterpreted.

This misalignment between the stories people tell and the ones listeners expect to hear happens all the time. We’ve all said things misunderstood by others. Sometimes this process is harmless; other times it results in difficult consequences. Dr. Kristiana Willsey writes about veterans who censor themselves in front of civilian audiences. Because civilians usually only expect to hear tales of “war heroes” or “PTSD survivors,” veterans often choose not to tell the full and complicated stories of their service experiences (Willsey, 2015). Dr. Amy Shuman and Carol Bohmer discuss the case of rejected asylum seekers. If asylum applicants don’t tell their stories of oppression and escape in a way that fits immigration officials’ expectations of what a traumatic asylum story should look like, their applications get denied (Shuman & Bohmer, 2016). If we consider just how different any two OCD stories can be and add the public assumption that OCD is an illness of specific doings (hand washing, checking locks) rather than tellings, it highlights just how difficult it is for most of these narratives to get heard, and heard correctly.

Patient/practitioner interactions can be particularly vulnerable to this type of miscommunication. The problem with considering OCD as just a medical issue is that most people don’t think of their lives as medical events. Practitioners enter the room ready to make sense of problems in clinical terms. Patients enter with stories. They share their concerns in a way that cannot be easily separated from their personal frames of reference or cultural understandings of life. Practitioners are often taught to mistrust the details that emerge from these narratives, to kindly but efficiently work around them in order to do their jobs. But for patients, these details are how they make meaning. If misdiagnoses also occur during these interactions, it’s worth taking a closer look at what’s being lost in translation.

Folklore ultimately offers the promise of new solutions to old problems. It allows us to reconsider how we listen to patients, collect data, and address communication issues— all clear benefits in the fight for better diagnostic care. It is also equipped to help us make sense out of the lived reality of OCD— perhaps uniquely so. I see folklore as an exciting potential ally to traditional research and clinical spaces. My hope is that this partnership can help us work more effectively toward our common goals: a better understanding of OCD, and quicker ease for its sufferers.

[Comment] The changing context of intergenerational health inequalities

Social inequalities in mortality and health have been recognised as serious public health issues since the 1980s, yet researchers continue to find social gradients in health nearly everywhere they look.1,2 Despite decades of research, our understanding of how and when socioeconomic factors and health interact to produce health inequalities remains work in progress. Some research on health inequalities has extended focus from adulthood social position to parental social background and early life conditions, and the accumulation of advantage and disadvantage across the life course.
