Readmission following hospital admission for community-acquired pneumonia in England.

INTRODUCTION: Readmission rates following hospital admission with community-acquired pneumonia (CAP) have increased in the UK over the past decade. The aim of this work was to describe the cohort of patients with emergency 30-day readmission following hospitalisation for CAP in England and explore the reasons for this. METHODS: A retrospective analysis of cases from the British Thoracic Society national adult CAP audit admitted to hospitals in England with CAP between 1 December 2018 and 31 January 2019 was performed. Cases were linked with corresponding patient level data from Hospital Episode statistics, providing data on the primary diagnosis treated during readmission and mortality. Analyses were performed describing the cohort of patients readmitted within 30 days, reasons for readmission and comparing those readmitted and primarily treated for pneumonia with other diagnoses. RESULTS: Of 8136 cases who survived an index admission with CAP, 1304 (15.7%) were readmitted as an emergency within 30 days of discharge. The main problems treated on readmission were pneumonia in 516 (39.6%) patients and other respiratory disorders in 284 (21.8%). Readmission with pneumonia compared with all other diagnoses was associated with significant inpatient mortality (15.9% vs 6.5%; aOR 2.76, 95% CI 1.86 to 4.09, p<0.001). A diagnosis of hospital-acquired infection was more frequent in readmissions treated for pneumonia than other diagnoses (22.1% vs 3.9%, p<0.001). CONCLUSION: Pneumonia is the most common condition treated on readmission following hospitalisation with CAP and carries a higher mortality than both the index admission or readmission due to other diagnoses. Strategies to reduce readmissions due to pneumonia are required.

COVID-19 Distress Impacts Adolescents' Depressive Symptoms, NSSI, and Suicide Risk in the Rural, Northeast US.

OBJECTIVE: Widespread concern exists about the impacts of COVID-19 and related public health safety measures (e.g., school closures) on adolescent mental health. Emerging research documents correlates and trajectories of adolescent distress, but further work is needed to identify additional vulnerability factors that explain increased psychopathology during the pandemic. The current study examined whether COVID-19-related loneliness and health anxiety (assessed in March 2020) predicted increased depressive symptoms, frequency of non-suicidal self-injury (NSSI), and suicide risk from pre-pandemic (late January/early February 2020) to June 2020. METHOD: Participants were 362 middle and high school adolescents in rural Maine (M age = 15.01 years; 63.4% female; 76.4% White). Data were collected during a time in which state-level COVID-19 restrictions were high and case counts were relatively low. Self-reports assessed psychopathology symptoms, and ecological momentary assessment (EMA) was used to capture COVID-19-related distress during the initial days of school closures. RESULTS: Loneliness predicted higher depressive symptoms for all adolescents, higher NSSI frequency for adolescents with low pre-pandemic frequency (but less frequent NSSI for adolescents with high pre-pandemic frequency), and higher suicide risk for adolescents with higher pre-pandemic risk. Health anxiety predicted higher NSSI frequency for adolescents with high pre-pandemic frequency, and secondary analyses suggested that this pattern may depend on adolescents' gender identity. CONCLUSIONS: Results underscore the impact of COVID-19 on adolescent mental health, with benefits for some but largely negative impacts for most. Implications for caretakers, educators, and clinicians invested in adolescent mental health are discussed.

Key Challenges and Potential Strategies for Engaging Youth with Lived Experience in Clinical Science.

Centering the perspectives of youth with lived experience (YWLE) in psychopathology is critical to engaging in impactful clinical research to improve youth mental health outcomes. Over the past decade there has been a greater push in clinical science to include community members, and especially community members with lived experience, in all aspects of the research process. The goal of this editorial is to highlight the need for and importance of integrating YWLE into every stage of clinical science research, from idea generation to interpretation and dissemination of research findings. We identify five key problems associated with pursuing research on adolescent mental health without involvement of YWLE and propose strategies to overcome barriers to youth engagement in clinical science research. We conclude with a call to action, providing guidance to clinical scientists, institutions, and funding agencies in conducting research on youth psychopathology with YWLE.

Pneumomediastinum in COVID-19: a phenotype of severe COVID-19 pneumonitis? The results of the United Kingdom (POETIC) survey.

BACKGROUND: There is an emerging understanding that coronavirus disease 2019 (COVID-19) is associated with increased incidence of pneumomediastinum. We aimed to determine its incidence among patients hospitalised with COVID-19 in the United Kingdom and describe factors associated with outcome. METHODS: A structured survey of pneumomediastinum and its incidence was conducted from September 2020 to February 2021. United Kingdom-wide participation was solicited via respiratory research networks. Identified patients had SARS-CoV-2 infection and radiologically proven pneumomediastinum. The primary outcomes were to determine incidence of pneumomediastinum in COVID-19 and to investigate risk factors associated with patient mortality. RESULTS: 377 cases of pneumomediastinum in COVID-19 were identified from 58 484 inpatients with COVID-19 at 53 hospitals during the study period, giving an incidence of 0.64%. Overall 120-day mortality in COVID-19 pneumomediastinum was 195/377 (51.7%). Pneumomediastinum in COVID-19 was associated with high rates of mechanical ventilation. 172/377 patients (45.6%) were mechanically ventilated at the point of diagnosis. Mechanical ventilation was the most important predictor of mortality in COVID-19 pneumomediastinum at the time of diagnosis and thereafter (p<0.001) along with increasing age (p<0.01) and diabetes mellitus (p=0.08). Switching patients from continuous positive airways pressure support to oxygen or high flow nasal oxygen after the diagnosis of pneumomediastinum was not associated with difference in mortality. CONCLUSIONS: Pneumomediastinum appears to be a marker of severe COVID-19 pneumonitis. The majority of patients in whom pneumomediastinum was identified had not been mechanically ventilated at the point of diagnosis.

"There is no joy in the family anymore": a mixed-methods study on the experience and impact of maternal mortality on families in Ghana.

BACKGROUND: Maternal mortality has a multifaceted impact on families, especially in low- and middle-income countries, where rates of maternal mortality are high and resources can be lacking. The objective of this study was to explore the ways that maternal mortality influences the physical and emotional wellbeing, financial stability, and caregiving structure of families, and identifies sources of and gaps in support. METHODS: Our study used a mixed-methods design. All maternal mortalities in an 18-month period at a tertiary hospital in Ghana were identified using death certificates. Participants were 51 family members (either husbands or other heads of households) in families affected by maternal mortality. A questionnaire assessed demographic characteristics and changes in family health, income, and family structure. Two validated scales assessing psychological wellbeing were administered: the Patient Health Questionnaire-9 and the Inventory of Complicated Grief. Semi-structured interviews were conducted to assess impact on family wellbeing. RESULTS: Quantitative and qualitative results converged to highlight large, negative impacts of maternal mortality on four areas of family wellbeing: 1) mental health and emotional wellbeing; 2) physical health; 3) family structure; 4) financial stability and security. On the Patient Health Questionnaire-9, 54% (27/50) of participants reported elevated depressive symptoms, with 14% (7/50) of scores falling in the moderately severe or severe ranges. On the Inventory of Complicated Grief, 38% (19/50) exceeded the cutoff for significant impairment in functioning. Worsened family health was associated with greater complicated grief (b = 21.41, p = .004); there were no other significant predictors of depressive symptom severity or complicated grief. Effects on family health centered on concerns about the nutritional status and health of the surviving infant. Family structure was primarily affected by fracturing of the central family unit by sending children to live with relatives. Immense economic strain resulted from hospital bills, funeral expenses, and loss of income. The majority of participants received helpful support from their family (41/51, 80.4%), the community (32/51, 62.7%), and their religious institution (43/51, 84.3%); however, support often stopped soon after the death. CONCLUSIONS: Maternal mortality has profound negative impacts on families in Ghana. Impacts are experienced by husbands and heads of households, as well as surviving children. Both immediate and sustained support is needed for families following a maternal death, especially mental health and financial support.

Effectiveness of the 23-valent pneumococcal polysaccharide vaccine against vaccine serotype pneumococcal pneumonia in adults: A case-control test-negative design study.

BACKGROUND: Vaccination with the 23-valent pneumococcal polysaccharide vaccine (PPV23) is available in the United Kingdom to adults aged 65 years or older and those in defined clinical risk groups. We evaluated the vaccine effectiveness (VE) of PPV23 against vaccine-type pneumococcal pneumonia in a cohort of adults hospitalised with community-acquired pneumonia (CAP). METHODS AND FINDINGS: Using a case-control test-negative design, a secondary analysis of data was conducted from a prospective cohort study of adults (aged ≥16 years) with CAP hospitalised at 2 university teaching hospitals in Nottingham, England, from September 2013 to August 2018. The exposure of interest was PPV23 vaccination at any time point prior to the index admission. A case was defined as PPV23 serotype-specific pneumococcal pneumonia and a control as non-PPV23 serotype pneumococcal pneumonia or nonpneumococcal pneumonia. Pneumococcal serotypes were identified from urine samples using a multiplex immunoassay or from positive blood cultures. Multivariable logistic regression was used to derive adjusted odds of case status between vaccinated and unvaccinated individuals; VE estimates were calculated as (1 - odds ratio) × 100%. Of 2,357 patients, there were 717 PPV23 cases (48% vaccinated) and 1,640 controls (54.5% vaccinated). The adjusted VE (aVE) estimate against PPV23 serotype disease was 24% (95% CI 5%-40%, p = 0.02). Estimates were similar in analyses restricted to vaccine-eligible patients (n = 1,768, aVE 23%, 95% CI 1%-40%) and patients aged ≥65 years (n = 1,407, aVE 20%, 95% CI -5% to 40%), but not in patients aged ≥75 years (n = 905, aVE 5%, 95% CI -37% to 35%). The aVE estimate in relation to PPV23/non-13-valent pneumococcal conjugate vaccine (PCV13) serotype pneumonia (n = 417 cases, 43.7% vaccinated) was 29% (95% CI 6%-46%). Key limitations of this study are that, due to high vaccination rates, there was a lack of power to reject the null hypothesis of no vaccine effect, and that the study was not large enough to allow robust subgroup analysis in the older age groups. CONCLUSIONS: In the setting of an established national childhood PCV13 vaccination programme, PPV23 vaccination of clinical at-risk patient groups and adults aged ≥65 years provided moderate long-term protection against hospitalisation with PPV23 serotype pneumonia. These findings suggest that PPV23 vaccination may continue to have an important role in adult pneumococcal vaccine policy, including the possibility of revaccination of older adults.

Admission to hospital in the UK at a weekend does not influence the prognosis of adults with community-acquired pneumonia.

Outcomes for adults with community-acquired pneumonia (CAP) admitted to hospital at the weekend were compared with those admitted during weekdays using data from the British Thoracic Society national CAP audits. Of 31 400 cases, 40.7% were weekend admissions; these patients were older (mean age 72 vs 71.3 years, p=0.001) and more likely to have high severity CAP (28.9% vs 27.1%, p trend 0.003) but had slightly lower adjusted 30-day inpatient mortality (aOR 0.94 95% CI 0.88 to 1.01) compared with those admitted during weekdays. More patients in the weekend group received antibiotics within 4 hours of admission (70.3% vs 68.7%, aOR 1.07 95% CI 1.01 to 1.12). We did not observe increased mortality for adults admitted at the weekend with CAP.

Pneumococcal serotype trends, surveillance and risk factors in UK adult pneumonia, 2013-18.

BACKGROUND: Changes over the last 5 years (2013-18) in the serotypes implicated in adult pneumococcal pneumonia and the patient groups associated with vaccine-type disease are largely unknown. METHODS: We conducted a population-based prospective cohort study of adults admitted to two large university hospitals with community-acquired pneumonia (CAP) between September 2013 and August 2018. Pneumococcal serotypes were identified using a novel 24-valent urinary monoclonal antibody assay and from blood cultures. Trends in incidence rates were compared against national invasive pneumococcal disease (IPD) data. Persons at risk of vaccine-type pneumonia (pneumococcal conjugate vaccine (PCV)13 and pneumococcal polysaccharide vaccine (PPV)23) were determined from multivariate analyses. FINDINGS: Of 2934 adults hospitalised with CAP, 1075 (36.6%) had pneumococcal pneumonia. The annual incidence of pneumococcal pneumonia increased from 32.2 to 48.2 per 100 000 population (2013-18), predominantly due to increases in PCV13non7-serotype and non-vaccine type (NVT)-serotype pneumonia (annual incidence rate ratio 1.12, 95% CI 1.04 to 1.21 and 1.19, 95% CI 1.10 to 1.28, respectively). Incidence trends were broadly similar to IPD data. PCV13non7 (56.9% serotype 3) and PPV23non13 (44.1% serotype 8) serotypes were identified in 349 (32.5%) and 431 (40.1%) patients with pneumococcal pneumonia, respectively. PCV13-serotype pneumonia (dominated by serotype 3) was more likely in patients in the UK pneumococcal vaccination clinical risk group (adjusted OR (aOR) 1.73, 95% CI 1.31 to 2.28) while PPV23-serotype pneumonia was more likely in patients outside the clinical risk group (aOR 1.54, 95% CI 1.13 to 2.10). INTERPRETATION: The incidence of pneumococcal CAP is increasing, predominantly due to NVT serotypes and serotype 3. PPV23-serotype pneumonia is more likely in adults outside currently identified clinical risk groups.

Imagery and verbal thought during rumination and distraction: Does imagery amplify affective response?

Rumination has long been considered a verbal thought process, though emerging evidence suggests that some individuals dwell on maladaptive imagery. This series of studies evaluated imagery and verbal thought during experimentally induced rumination and distraction. In Study 1, imagery and verbal thought during rumination resulted in similar increases in negative affect. Greater imagery during distraction, on the other hand, was associated with greater decreases in negative affect while verbal thought was not related to affect change. Given that greater verbal thought was reported in the rumination condition and greater imagery was reported in the distraction condition, Study 2 evaluated whether the rumination/distraction induction was confounded by concurrent induction of imagery or verbal thought. The rumination prompts induced both rumination and verbal thought and the distraction prompts induced both distraction and imagery. Using a revised induction, Study 3 tested whether imagery and verbal thought during rumination and distraction impacted affective response. Rumination maintained negative affect and distraction relieved negative affect, regardless of the degree to which imagery or verbal thought was experienced. This paper provides evidence that imagery-based rumination is just as impairing as verbally-based rumination and highlights imagery-based distraction as a potentially effective alternative to rumination.

The Opportunities and Risks of Large Language Models in Mental Health.

Unlabelled: Global rates of mental health concerns are rising, and there is increasing realization that existing models of mental health care will not adequately expand to meet the demand. With the emergence of large language models (LLMs) has come great optimism regarding their promise to create novel, large-scale solutions to support mental health. Despite their nascence, LLMs have already been applied to mental health-related tasks. In this paper, we summarize the extant literature on efforts to use LLMs to provide mental health education, assessment, and intervention and highlight key opportunities for positive impact in each area. We then highlight risks associated with LLMs' application to mental health and encourage the adoption of strategies to mitigate these risks. The urgent need for mental health support must be balanced with responsible development, testing, and deployment of mental health LLMs. It is especially critical to ensure that mental health LLMs are fine-tuned for mental health, enhance mental health equity, and adhere to ethical standards and that people, including those with lived experience with mental health concerns, are involved in all stages from development through deployment. Prioritizing these efforts will minimize potential harms to mental health and maximize the likelihood that LLMs will positively impact mental health globally.

Measures of Suicidal Thoughts and Behaviors in Children and Adolescents: A Systematic Review and Recommendations for Use in Clinical and Research Settings.

Empirically supported measures of suicidal thoughts and behaviors (STBs) are needed to serve as reference outcomes for suicide risk screening tools and to monitor severity and treatment progress in children and adolescents with STBs. The present paper systematically reviewed existing measures of STBs in youth and studies evaluating their psychometric properties and clinical utility. Measures were then evaluated on reliability, validity, and clinical utility. Sixteen articles (20 independent samples) were found with psychometric data with youth samples for eight measures. Interview-based measures were found to have the strongest psychometric support and clinical utility. Significant limitations exist for all self-report measures due to inherent characteristics of these measures that cannot be remedied through additional psychometric study. There is an urgent need for the development and validation of new self-report measures of STBs, particularly for preadolescent children, sexual and gender minority youth, and racial/ethnic minority youth.

A Suicide Prevention Digital Technology for Individuals Experiencing an Acute Suicide Crisis in Emergency Departments: Naturalistic Observational Study of Real-World Acceptability, Feasibility, and Safety.

BACKGROUND: Emergency departments (EDs) are the front line in providing suicide care. Expert consensus recommends the delivery of several suicide prevention evidence-based interventions for individuals with acute suicidal ideation in the ED. ED personnel demands and staff shortages compromise delivery and contribute to long wait times and unnecessary hospitalization. Digital technologies can play an important role in helping EDs deliver suicide care without placing further demands on the care team if their use is safe to patients in a routine care context. OBJECTIVE: This study evaluates the safety and effectiveness of an evidence-based digital technology (Jaspr Health) designed for persons with acute suicidal ideation seeking psychiatric crisis ED services when used as part of routine ED-based suicide care. This study deployed Jaspr Health for real-world use in 2 large health care systems in the United States and aimed to evaluate (1) how and whether Jaspr Health could be safely and effectively used outside the context of a researcher-facilitated clinical trial, and (2) that Jaspr's use would be associated with improved patient agitation and distress. METHODS: Under the auspices of a nonsignificant risk device study, ED patients with acute suicidal ideation (N=962) from 2 health care systems representing 10 EDs received access to Jaspr Health as part of their routine suicide care. Primary outcome measures included how many eligible patients were assigned Jaspr Health, which modules were assigned and completed, and finally, the number of adverse events reported by patients or by medical staff. Secondary outcome measures were patient agitation, distress, and satisfaction. RESULTS: The most frequent modules assigned were Comfort and Skills (98% of users; n=942) and lethal means assessment (90% of patient users; n=870). Patient task completion rates for all modules ranged from 51% to 79%. No adverse events were reported, suggesting that digital technologies can be safely used for people seeking ED-based psychiatric services. Statistically significant (P<.001) reductions in agitation and distress were reported after using the app. Average patient satisfaction ratings by site were 7.81 (SD 2.22) and 7.10 (SD 2.65), with 88.8% (n=325) and 84% (n=90) of patients recommending the app to others. CONCLUSIONS: Digital technologies such as Jaspr Health may be safely and effectively integrated into existing workflows to help deliver evidence-based suicide care in EDs. These findings hold promise for the use of digital technologies in delivering evidence-based care to other vulnerable populations in complex environments.

Carriage of Streptococcus pneumoniae in adults hospitalised with community-acquired pneumonia.

OBJECTIVES: We aimed to determine the prevalence of and risk factors for nasopharyngeal and oral pneumococcal carriage in adults with community-acquired pneumonia (CAP), and the relationship between carried and disease-causing serotypes. METHODS: Between 2016 and 2018, nasopharyngeal swabs, oral-fluid, and urine were collected from hospitalised adults recruited into a prospective cohort study of CAP. Pneumococcal carriage was detected by semi-quantitative real-time PCR of direct and culture-enriched nasopharyngeal swabs and culture-enriched oral-fluid. LytA and piaB positive/indeterminate samples underwent semi-quantitative serotype/serogroup-specific real-time-PCR. Serotypes in urine were identified using a 24-valent serotype-specific urinary-antigen assay. RESULTS: We included 465 CAP patients. Nasopharyngeal carriage was detected in 34/103 (33.0%) swabbed pneumococcal pneumonia patients and oral carriage in 18/155 (12%) of sampled pneumococcal pneumonia patients. Concordance between nasopharyngeal/urine serotypes and oral/urine serotypes was 70.6% and 50% respectively. Serotypes 3 (26%, 22.2%), 8 (19.7%, 19.4%), non-typeable (11.6%, 13.9%) and 19A/F (7.5%, 8.3%) were most prevalent in urine and nasopharyngeal swabs respectively, with non-typeable (35%) and 15A/F (17%) most prevalent in oral-fluid. Pneumococcal carriage was significantly associated with pneumococcal pneumonia (nasopharyngeal adjusted odds ratio [aOR] 8.1, 95% confidence interval [CI] 3.8-17.2; oral aOR 5.5, 95% CI 2.1-13.3). All-cause CAP patients ≥65 years had lower odds of nasopharyngeal carriage (aOR 0.47, 95% CI 0.24-0.91) and current smokers had higher odds of oral carriage (aOR 2.69, 95% CI 1.10-6.60). CONCLUSIONS: The association between nasopharyngeal carriage and pneumococcal CAP was strong. Adult carriage and disease from serotypes 8 and 19A may support direct protection of adults with PCV vaccines.

Assessment of suicidal thoughts and behaviors in adults: A systematic review of measure psychometric properties and implications for clinical and research utility.

High-quality clinical care and research on suicidal thoughts and behaviors (STBs) depends on availability and implementation of reliable and valid measures of STBs. In contrast to studies examining STB risk factors, screening instruments, or treatment, little research has rigorously examined the content, characteristics, and psychometric properties of STB measures themselves. This systematic review (1) identified STB measures that conform to empirically supported definitions of STBs, and (2) identified peer-reviewed papers reporting on the psychometric properties of these measures in adults. Data on psychometric properties and other measure characteristics were extracted. A total of 21 eligible measures were identified in the first stage. In the second stage, 70 articles (with 79 independent samples) were included with psychometric data in adult samples for 19 measures. Although there was support for strong internal consistency and content validity across many measures, face validity and clinical utility concerns were prevalent. Few measures comprehensively assessed suicidal behaviors, and interview-based assessments tended to show the strongest psychometric properties and clinical utility. Findings are discussed in the context of recommendations for improving existing measures, including future research to increase utility and translatability across clinical settings, delivery methods, and diverse populations.

Pneumococcal serotypes and risk factors in adult community-acquired pneumonia 2018-20; a multicentre UK cohort study.

Background: Higher-valency pneumococcal vaccines are anticipated. We aimed to describe serotype distribution and risk factors for vaccine-serotype community-acquired pneumonia (CAP) in the two years pre-SARS-CoV-2 pandemic. Methods: We conducted a prospective cohort study of adults hospitalised with CAP at three UK sites between 2018 and 2020. Pneumococcal serotypes were identified using a 24-valent urinary-antigen assay and blood cultures. Risk factors associated with vaccine-type pneumonia caused by serotypes in the 13-, 15- and 20-valent pneumococcal conjugate vaccines (PCV13, PCV15, PCV20) and 23-valent pneumococcal polysaccharide vaccine (PPV23) were determined from multivariable analysis. Findings: Of 1921 adults hospitalised with CAP, 781 (40.7%, 95% confidence intervals (CI) 38.5-42.9%) had pneumococcal pneumonia. A single PCV13-serotype was detected in 242 (31.0%, 95% CI 27.8-34.3%) pneumococcal CAP patients, mostly serotype 3 (171/242, 70.7%, 95% CI 64.5-76.0%). The additional two PCV15-serotypes were detected in 31 patients (4%, 95% CI 2.8-5.6%), and PCV20-non13-serotypes in 192 (24.6%), with serotype 8 most prevalent (123/192, 64.1%, 95% CI 57.1-70.5%). Compared to PCV13-serotype CAP, people with PCV20-non13 CAP were younger (median age 62 versus 72 years, p < 0.001) and less likely to be male (44% versus 61%, p = 0.01). PPV23-non13-serotypes were found in 252 (32.3%, 95% CI 29.1-35.6%) pneumococcal CAP patients. Interpretation: Despite mature infant pneumococcal programmes, the burden of PCV13-serotype pneumonia remains high in older adults, mainly due to serotype 3. PCV20-non13-serotype pneumonia is more likely in younger people with fewer pneumococcal risk factors.

The Relationship of the PROMIS® Pediatric Physical Activity Measure with Cardiorespiratory Fitness.

A The PROMIS® Pediatric Physical Activity (PA) measure is a new instrument with established validity that measures a child self-report on short bouts of moderate to rigorous physical activity. The purpose of this study was to explore the relationship of the PROMIS® Pediatric PA item bank with cardiorespiratory fitness and self-efficacy. The study was conducted at the Minnesota State Fair. Youth ages 8 to 18 years completed the PROMIS® Pediatric PA and the Self-Efficacy for PA measures on an iPad. Participants performed 3-min step test with heart rates measured 1 min posttest. Participants (N = 182) were 53% female. The PROMIS® Pediatric PA had a weak, significant negative correlation with the step test measurement (r = -0.23, p = 0.001) and a weak, significant positive correlation with self-efficacy (r = 0.27, p < 0.001). Measurements did not differ between groups by sex or age group (school-age and adolescent). Youth who were obese had significantly higher heart rates post step test (p = 0.004); BMI percentile groups did not differ in other measures. Self-report of PA and the physiologic measure of heart rate are from two related but different physical fitness domains which supports their significant but weak relationship.

Reimagining rumination? The unique role of mental imagery in adolescents' affective and physiological response to rumination and distraction.

Rumination is associated with increased risk for depression whereas distraction helps draw attention away from negative experiences, lowering risk. Many individuals who ruminate do so in the form of mental imagery and imagery-based rumination is more highly associated with depressive symptom severity than ruminating in the form of verbal thoughts. We do not yet understand why imagery-based rumination may be especially problematic nor how to intervene to reduce imagery-based rumination, however. Adolescents (N = 145) underwent a negative mood induction followed by experimental induction of rumination or distraction in the form of mental imagery or verbal thought while affective, high-frequency heart rate variability, and skin conductance response data were collected. Rumination was associated with similar affective, high-frequency heart rate variability, and skin conductance response regardless of whether adolescents were induced to ruminate in the form of mental imagery or verbal thought. Distraction led to greater affective improvement and greater increases in high-frequency heart rate variability, but similar skin conductance responses when adolescents were inducted to distract themselves in the form of mental imagery compared with verbal thought. Findings emphasize the importance of considering mental imagery in clinical contexts when assessing rumination and when intervening using distraction.

Mental imagery of suicide and non-suicidal self-injury: A meta-analysis and systematic review.

BACKGROUND: The vast majority of research on, and clinical assessment of, cognitions related to suicide and non-suicidal self-injury (NSSI) has focused on verbal thoughts. And yet, mental imagery is more realistic and emotionally arousing than verbal thoughts. METHODS: We conducted a systematic review and meta-analysis documenting the prevalence of suicidal and NSSI mental imagery and describing the content and characteristics of suicidal and NSSI mental imagery, links between suicidal and NSSI mental imagery and suicidal and NSSI behavior, and how to intervene on suicidal and NSSI mental imagery. Studies published through December 17, 2022 were identified through a systematic search of MEDLINE and PsycINFO. RESULTS: Twenty-three articles were included. Prevalence rates of suicidal (73.56%) and NSSI (84.33%) mental imagery were high among clinical samples. Self-harm mental imagery commonly depicts engagement in self-harm behavior and is experienced as vivid, realistic, and preoccupying. When experimentally induced, self-harm mental imagery reduces physiological and affective arousal. Preliminary evidence suggests that suicidal mental imagery is associated with suicidal behavior. CONCLUSIONS: Suicidal and NSSI mental imagery are highly prevalent and may be associated with heightened risk for self-harm behavior. Assessments and interventions for self-harm should consider incorporating and addressing suicidal and NSSI mental imagery to mitigate risk.

Using the Delphi Method for Determining Key Performance Elements for Delivery of Optimal Suicide-Specific Interventions in Emergency Departments.

OBJECTIVE: Evidence-based suicide prevention interventions directed to those seeking psychiatric crisis services for suicidality in the emergency department (ED) can reduce death by suicide and related suffering. Best practice guidelines for the care of suicidal patients in the ED exist but are not accompanied by fidelity tools for use in determining whether the interventions were applied, particularly when more than one intervention is delivered concurrently. We sought to develop a universal, treatment-agnostic Suicide Care Fidelity Checklist comprised of Key Performance Elements (KPE) across the recommended suicide-specific ED interventions. METHOD: A comprehensive review of published care standards was first conducted to determine suicide-specific ED best practice treatment domains and KPEs. Subject matter experts (SMEs) were identified for each domain. Using the Delphi Consensus method, SMEs iteratively revised and refined the KPEs within their domain until achieving KPE item consensus. RESULTS: A total of three iterations was required to obtain consensus in five of six domains: comprehensive suicide assessment, lethal means counseling, suicide crisis planning, behavioral skills training, and psychoeducation about suicidality. Consensus was not fully attained for the domain involving engagement with people with lived experience. CONCLUSIONS: We successfully identified six intervention domains and 74 KPEs across domains (60 deemed essential, and 14 deemed optional), with full consensus reached for 70 KPEs. While replication of the initial findings is required, the Suicide Care Fidelity Checklist can be used as a fidelity checklist to verify delivery of suicide-specific ED interventions.HIGHLIGHTSApplied Delphi Consensus method with suicide-specific subject matter experts.Generated a treatment-agnostic, universal set of suicide prevention KPEs for EDs.Expert-derived KPEs help real-world settings to assess suicide care fidelity.

Nonsuicidal Self-Injury in Preadolescents.

OBJECTIVES: There is a dearth of literature on the prevalence and predictors of nonsuicidal self-injury (NSSI) history and onset among preadolescent youth. This gap in the literature is significant given evidence suggesting that NSSI is a robust predictor of negative mental health outcomes, and that early onset NSSI may be associated with a more severe course of self-injurious thoughts and behaviors. This study aimed to evaluate sociodemographic characteristics, psychiatric disorders, and suicidal ideation (SI) in relation to NSSI onset and history in preadolescents. METHODS: Data were drawn from the Adolescent Brain and Cognitive Development (ABCD) study, which recruited a diverse sample of 11 875 youth aged 9 to 10 years. The primary outcome measures were lifetime history and recent onset of NSSI. Measures included sociodemographics and the K-SADS diagnostic interview assessing psychopathology and SI. RESULTS: Female sex and identifying as Black were associated with lower odds of lifetime NSSI. Identifying as a sexual minority, having unmarried parents, and a low family income were associated with higher odds of lifetime NSSI. Although depression was most predictive of NSSI history and onset, a range of internalizing and externalizing disorders, greater comorbidity, and SI also were predictive. CONCLUSIONS: Given that NSSI was associated with a range of mental health disorders and comorbidity, it may be best conceptualized as a transdiagnostic phenomenon. Findings highlight key sociodemographic and diagnostic factors that may help to direct screening efforts in preadolescents, particularly sexual minority status and depression.
