Cross-cultural equivalence of the Kessler Psychological Distress Scale (K10) across four African countries in a multi-national study of adults.

The Kessler Psychological Distress Scale (K10) has been widely used to screen psychological distress across many countries. However, its performance has not been extensively studied in Africa. The present study sought to evaluate and compare measurement properties of the K10 across four African countries: Ethiopia, Kenya, Uganda, and South Africa. Our hypothesis is that the measure will show equivalence across all. Data are drawn from a neuropsychiatric genetic study among adult participants (N = 9179) from general medical settings in Ethiopia (n = 1928), Kenya (n = 2556), Uganda (n = 2104), and South Africa (n = 2591). A unidimensional model with correlated errors was tested for equivalence across study countries using confirmatory factor analyses and the alignment optimization method. Results displayed 30 % noninvariance (i.e., variation) for both intercepts and factor loadings across all countries. Monte Carlo simulations showed a correlation of 0.998, a good replication of population values, indicating minimal noninvariance, or variation. Items "so nervous," "lack of energy/effortful tasks," and "tired" were consistently equivalent for intercepts and factor loadings, respectively. However, items "depressed" and "so depressed" consistently differed across study countries (R2 = 0) for intercepts and factor loadings for both items. The K10 scale likely functions equivalently across the four countries for most items, except "depressed" and "so depressed." Differences in K10 items were more common in Kenya and Ethiopia, suggesting cultural context may influence the interpretation of some items and the potential need for cultural adaptations in these countries.

Childhood maltreatment and health in the UK Biobank: triangulation of outcome-wide and polygenic risk score analyses.

BACKGROUND: Childhood maltreatment is common globally and impacts morbidity, mortality, and well-being. Our understanding of its impact is constrained by key substantive and methodological limitations of extant research, including understudied physical health outcomes and bias due to unmeasured confounding. We address these limitations through a large-scale outcome-wide triangulation study. METHODS: We performed two outcome-wide analyses (OWAs) in the UK Biobank. First, we examined the relationship between self-reported maltreatment exposure (number of maltreatment types, via Childhood Trauma Screener) and 414 outcomes in a sub-sample of 157,316 individuals using generalized linear models ("observational OWA"). Outcomes covered a broad range of health themes including health behaviors, cardiovascular disease, digestive health, socioeconomic status, and pain. Second, we examined the relationship between a polygenic risk score for maltreatment and 298 outcomes in a non-overlapping sample of 243,006 individuals ("genetic OWA"). We triangulated results across OWAs based on differing sources of bias. RESULTS: Overall, 23.8% of the analytic sample for the observational OWA reported at least one maltreatment type. Of 298 outcomes examined in both OWAs, 25% were significant in both OWAs and concordant in the direction of association. Most of these were considered robust in the observational OWA according to sensitivity analyses and included outcomes such as marital separation (OR from observational OWA, ORo = 1.25 (95% CI: 1.21, 1.29); OR from genetic OWA, ORg = 1.06 (1.03, 1.08)), major diet changes due to illness (ORo = 1.27 (1.24, 1.29); ORg = 1.01 (1.00, 1.03)), certain intestinal diseases (ORo = 1.14 (1.10, 1.18); ORg = 1.03 (1.01, 1.06)), hearing difficulty with background noise (ORo = 1.11 (1.11, 1.12); ORg = 1.01 (1.00, 1.01)), knee arthrosis (ORo = 1.13 (1.09, 1.18); ORg = 1.03 (1.01, 1.05)), frequent sleeplessness (ORo = 1.21 (1.20, 1.23); ORg = 1.02 (1.01, 1.03)), and low household income (ORo = 1.28 (1.26, 1.31); ORg = 1.02 (1.01, 1.03)). Approximately 62% of results were significant in the observational OWA but not the genetic OWA, including numerous cardiovascular outcomes. Only 6 outcomes were significant in the genetic OWA and null in the observational OWA; these included diastolic blood pressure and glaucoma. No outcomes were statistically significant in opposite directions in the two analyses, and 11% were not significant in either OWA. CONCLUSIONS: Our findings underscore the far-reaching negative effects of childhood maltreatment in later life and the utility of an outcome-wide triangulation design with sensitivity analyses for improving causal inference.

Post-traumatic stress and future substance use outcomes: leveraging antecedent factors to stratify risk.

Background: Post-traumatic stress disorder (PTSD) and substance use (tobacco, alcohol, and cannabis) are highly comorbid. Many factors affect this relationship, including sociodemographic and psychosocial characteristics, other prior traumas, and physical health. However, few prior studies have investigated this prospectively, examining new substance use and the extent to which a wide range of factors may modify the relationship to PTSD. Methods: The Advancing Understanding of RecOvery afteR traumA (AURORA) study is a prospective cohort of adults presenting at emergency departments (N = 2,943). Participants self-reported PTSD symptoms and the frequency and quantity of tobacco, alcohol, and cannabis use at six total timepoints. We assessed the associations of PTSD and future substance use, lagged by one timepoint, using the Poisson generalized estimating equations. We also stratified by incident and prevalent substance use and generated causal forests to identify the most important effect modifiers of this relationship out of 128 potential variables. Results: At baseline, 37.3% (N = 1,099) of participants reported likely PTSD. PTSD was associated with tobacco frequency (incidence rate ratio (IRR): 1.003, 95% CI: 1.00, 1.01, p = 0.02) and quantity (IRR: 1.01, 95% CI: 1.001, 1.01, p = 0.01), and alcohol frequency (IRR: 1.002, 95% CI: 1.00, 1.004, p = 0.03) and quantity (IRR: 1.003, 95% CI: 1.001, 1.01, p = 0.001), but not with cannabis use. There were slight differences in incident compared to prevalent tobacco frequency and quantity of use; prevalent tobacco frequency and quantity were associated with PTSD symptoms, while incident tobacco frequency and quantity were not. Using causal forests, lifetime worst use of cigarettes, overall self-rated physical health, and prior childhood trauma were major moderators of the relationship between PTSD symptoms and the three substances investigated. Conclusion: PTSD symptoms were highly associated with tobacco and alcohol use, while the association with prospective cannabis use is not clear. Findings suggest that understanding the different risk stratification that occurs can aid in tailoring interventions to populations at greatest risk to best mitigate the comorbidity between PTSD symptoms and future substance use outcomes. We demonstrate that this is particularly salient for tobacco use and, to some extent, alcohol use, while cannabis is less likely to be impacted by PTSD symptoms across the strata.

Bereavement, Memorial Attendance, and Mental Health During the COVID-19 Pandemic: Longitudinal Results from the Nurses' Health Study.

BACKGROUND: Mortality increased during the COVID-19 pandemic. Many bereaved individuals were not able to gather to memorialize their loved ones, yet it is unknown if this contributed to worsening mental health. OBJECTIVE: Examine the association of bereavement in the early part of the COVID-19 pandemic with subsequent psychological distress and the role of memorial attendance in reducing psychological distress among the bereaved. DESIGN, SETTINGS, SUBJECTS: In May 2020, 39,564 older females from the Nurses' Health Study II enrolled in a longitudinal COVID-19 substudy (meanage = 65.2 years, SD = 4.5). METHODS: Linear regression analyses estimated associations of bereavement reported between March and October, 2020 with subsequent psychological distress between January and October 2021, adjusting for sociodemographic and prepandemic depression symptoms. Secondary models examined associations between memorial attendance and psychological distress. RESULTS: Bereavement during the early part of the COVID-19 pandemic was associated with higher psychological distress (adjusted ß = 0.21, 95% CI: 0.15, 0.26) assessed over the next year. Among the bereaved, memorial attendance was associated with lower psychological distress (in-person: adjusted ß = -0.41, 95% CI: -0.53, -0.29; online: adjusted ß = -0.24, 95% CI: -0.46, --0.02). CONCLUSION: Attending memorials was associated with lower subsequent psychological distress among bereaved older females.

Mental health among bereaved youth in the ALSPAC birth cohort: Consideration of early sociodemographic precursors, cognitive ability, and type of loss.

BACKGROUND: Bereaved youth are at greater risk for adverse mental health outcomes, yet less is known about how social context shapes health for bereaved children. Ecosocial theory is employed to conceptualize bereavement in the context of sociodemographic factors. METHOD: This longitudinal study used data from the Avon Longitudinal Study of Parents and Children. Of the 15,454 pregnancies enrolled, 5050 youth were still enrolled at age 16.5 and completed self-report questionnaires on life events and emotional/behavioral symptoms. RESULTS: Sociodemographic precursors associated with parent, sibling, or close friend bereavement included maternal smoking, parental education levels, and financial difficulties. The significant yet small main effect of higher cognitive ability, assessed at age 8, on reduced emotional/behavioral symptoms at age 16.5 (ß = -0.01, SE = 0.00, p < 0.001) did not interact with bereavement. Bereavement of a parent, sibling, or close friend was associated with a 0.19 point higher emotional/behavioral symptom log score compared to non-bereaved youth (95% CI: 0.10-0.28), across emotional, conduct, and hyperactivity subscales. CONCLUSIONS: Descriptive findings suggest sociodemographic precursors are associated with bereavement. While there was an association between the bereavement of a parent, sibling, or close friend and elevated emotional/behavioral symptoms, cognitive ability did not moderate that effect.

Resilient phenotypes among bereaved youth: a comparison of trajectory, relative, and cross-domain approaches.

BACKGROUND: Bereavement is a common traumatic event associated with adverse health outcomes across the life course. Despite these risks, not all bereaved individuals experience these negative effects. Limited scientific consensus exists on how to define resilience in individuals who have experienced the death of a loved one. METHODS: Using a sample of N = 3766 youth from the Avon Longitudinal Study of Parents and Children birth cohort, we identified bereavement of a family member between ages 7 and 8.5. We derived and compared three different approaches to assess resilience among bereaved youth. Trajectory-based psychological resilience identified sub-groups with similar psychological symptom profiles between ages 6 and 16 using latent growth mixture models. Relative psychological resilience at age 16 leveraged standardized residuals from a model regressing psychological symptoms on bereavement to determine better-than-expected psychological functioning relative to bereavement status. Relative cross-domain resilience around age 16 was a sum score of the residuals approach applied to eight unique domains of health. Predictive validity of each approach was assessed using depressive symptoms at age 17.5 RESULTS: Overall, N = 877 (23%) youth were bereaved of a family member between ages 7 and 8.5. Using latent growth mixture models, a three-class solution described 84% of bereaved youth with low and stable psychological symptoms over time, 8% with worsening symptoms, and 8% with improving yet elevated symptoms. Each relative resilience score was largely concordant with the trajectory-based approach in identifying individuals as resilient or not, though relative psychological resilience demonstrated a stronger degree of concordance than the cross-domain score. Relative psychological and cross-domain resilience exhibited moderate to low correlation, depending on the domains included (r = 0.14-0.43). For each approach, resilience significantly predicted lower depressive symptoms at age 17.5, highlighting predictive validity of these measures. CONCLUSIONS: Psychological symptom trajectories among bereaved youth aligned with those previously identified among bereaved adults. The residual-based approach to defining resilience exhibited limited utility in the context of bereavement. When identifying risk and resilience after bereavement, researchers and clinicians must address the interplay across psychosocial and physical health domains, as bereaved youth considered resilient from a mental health perspective may benefit from intervention in other domains.

Prevalence of Substance Use and Its Association with Sociodemographic and Behavioral Factors among Women Who Conduct Sex Work in Kenya.

Female sex workers (FSWs) in sub-Saharan Africa are a marginalized group with an increased morbidity risk. Psychoactive substance use among this group is common and increases the risk of adverse health consequences. The type of substance used, extent, and nature of use varies with different settings and regions. We examine the use of specific psychoactive substances among FSWs residing in an urban informal settlement in Nairobi. This cross-sectional study was conducted between April and August 2017. Structured questionnaires were administered in face-to-face interviews. Descriptive statistics and logistic regression were undertaken to examine prevalence, patterns, and factors associated with use of specific substances. Out of 301 FSWs, 98% reported current psychoactive substance use. The most used substance was alcohol with 95.6% of the study population reporting use in the past year. Of these, 151 (50.2%) met criteria for very high-risk drinkers. Reported current use was 61.5% for cannabis, 47.2% for khat, and 30.9% for tobacco. Factors independently associated with hazardous and harmful alcohol use included earning a higher monthly income (>USD50) and disclosure of sex work to close family and friends. There is an urgent need for preventive and curative interventions to address the high prevalence of substance use among FSW residing in high-risk urban informal settlements in Kenya.

A Longitudinal Investigation of Resilience as a Protective Factor During the COVID-19 Pandemic.

COVID-19 is a global stressor that has been shown to impact mental health outcomes. Given that COVID-19 is a unique stressor that has been shown to have mental health consequences, identifying protective factors is imperative. The protective influences of resilience are demonstrated through the extant literature, though less is known about resilience and COVID-19 impact. The current study seeks to expand the existing literature on resilience, and on mental health outcomes influenced by COVID-19, by longitudinally investigating relative resilience as a buffer against posttraumatic stress disorder (PTSD) symptoms and alcohol consumption, in the wake of a global pandemic. Participants included 549 undergraduates with a history of lifetime trauma exposure. Using a longitudinal path model, we tested the interaction between relative resilience (i.e., an individual's deviation from distress levels predicted by prior trauma exposure relative to other individuals in the same cohort) and COVID-19 impact domains (i.e., social media use, worry, exposure, change in substance use, and housing/food insecurity) on PTSD symptoms and alcohol consumption. Findings demonstrate a significant interaction between the COVID-19 worry impact domain and baseline resilience on later PTSD symptoms, whereby COVID-19 worry impacts PTSD symptoms at low levels of resilience (ß = .26, p < .001), marginally impacts PTSD symptoms at mean levels of resilience (ß = .09, p = .05), and does not impact PTSD symptoms at high levels of resilience (ß = -.08, p = .16). There were no significant main effects nor interaction effects of resilience on alcohol consumption. This article adds to the literature on resilience and COVID-19 through examining both internalizing (i.e., PTSD) and substance use outcomes, using longitudinal data, and using a quantitative measure of resilience.

Social Determinants Associated With Exposure to Childhood Parental Bereavement and Subsequent Risk for Psychiatric Disorders.

Importance: Prevalence of childhood parental death varies by race and ethnicity and socioeconomic status, yet whether similar variation persists in the association with lifetime psychiatric disorder is unknown. Objective: To assess whether race and ethnicity and parental educational attainment are associated with the risk of death of a parent; to determine whether the risk for lifetime psychiatric disorder associated with death of a parent was moderated by race and ethnicity and highest parental educational attainment; and to examine a potential intersection of race and ethnicity with parental educational attainment in the risk of lifetime psychiatric disorder associated with death of a parent. Design, Setting, and Participants: This retrospective cohort study used data from the National Comorbidity Study: Adolescent Supplement (NCS-A), 2001 to 2004. Participants included youth aged 13 to 18 years, restricted to Black, Hispanic, and White youth due to power limitations. Data were analyzed from February 26, 2021, to April 21, 2022. Exposure: Death of a parent during childhood. Main Outcomes and Measures: The primary study outcome was any lifetime Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) psychiatric disorder, assess via assessed via structured clinical interviews. Results: Among 9501 youth (mean [SD] age, 15.2 [1.5] years; 50.9% female), including 511 youth who had experienced parental death and 8990 youth who had not, the cumulative hazard of parental death by age 18 years was approximately doubled for Hispanic (10.1%; 95% CI, 6.9%-14.7%) and Black (14.0%; 95% CI, 10.6%-18.4%) youth compared with White youth (6.0%; 95% CI, 4.7%-7.8%). Similar patterns were noted by parental educational attainment: the cumulative hazard of parental death for youth of parents with less educational attainment was nearly double (10.1%; 95% CI, 8.1%-12.6%) compared with youth of parents with more education (6.6%; 95% CI, 5.2%-8.4%). Death of a parent was positively and significantly associated with risk of any lifetime psychiatric disorder (aOR, 1.34; 95% CI, 1.03-1.75) compared with youth who had not experienced death of a parent. However, this association was not moderated by race and ethnicity (aOR, 1.05; 95% CI, 0.58-1.92) or parental educational attainment (aOR, 1.19; 95%, 0.70-2.04), although power analyses suggest that larger sample sizes are needed. Conclusions and Relevance: In this cross-sectional study, Black and Hispanic youth experienced elevated parental death compared with White youth, yet the risk for any lifetime psychiatric disorder after parental death was not significantly moderated by race and ethnicity or parental education. Both individual- and population-level interventions may be needed to address the increased risk of psychiatric disorders, although additional studies with larger sample sizes are needed.

Influence of Maternal Childhood Trauma on Perinatal Depression, Observed Mother-Infant Interactions, and Child Growth.

INTRODUCTION: Mothers who have experienced childhood trauma may be at increased risk for disruptions in caregiving behavior, with potential consequences for early child development. However, assessments of caregiving behavior tend to be self-reported, which may bias results, and have been limited in lower-resource settings. METHODS: In an overall sample of 256 South African mothers followed across the perinatal period, this longitudinal study used structural equation modeling to test pathways of association between maternal childhood trauma and depressive symptoms on observed mother-infant interactions at 3.5 months and subsequent child growth outcomes at 1 year. RESULTS: On average, mothers with childhood trauma histories tended to show lower rated overall interactions with their infants (B = - 0.16, p = .013), which in turn was associated with reduced child growth at 1 year (B = 0.17, p = .046). When this model was adjusted for maternal age and relative socioeconomic status (SES), maternal SES strongly explained child growth (B = 0.31, p < .001) such that the direct effect of mother-infant interactions was no longer significant. DISCUSSION: For child growth in a lower-resource setting, quality of mother-infant interactions could be a relevant predictor but more strongly explained by maternal SES factors, suggesting a need for broader approaches that not only improve dyadic relationships but also address maternal ecological resources.

Cross-country variations in the reporting of psychotic symptoms among sub-Saharan African adults: A psychometric evaluation of the Psychosis Screening Questionnaire.

BACKGROUND: Self-reporting of psychotic symptoms varies significantly between cultures and ethnic groups. Yet, limited validated screening instruments are available to capture such differences in the African continent. METHODOLOGY: Among 9,059 individuals participating as controls in a multi-country case-control study of the genetic causes of psychosis, we evaluated the psychometric properties of the Psychosis Screening Questionnaire (PSQ). We applied multi-group confirmatory factor analysis and item response theory to assess item parameters. RESULTS: The overall positive endorsement of at least one item assessing psychotic symptoms on the PSQ was 9.7%, with variability among countries (Uganda 13.7%, South Africa 11%, Kenya 10.2%, and Ethiopia 2.8%). A unidimensional model demonstrated good fit for the PSQ (root mean square error of approximation = 0.009; comparative fit index = 0.997; and Tucker-Lewis Index = 0.995). Hypomania had the weakest association with single latent factor (standardized factor loading 0.62). Sequential multi-group confirmatory factor analysis demonstrated that PSQ items were measured in equivalent ways across the four countries. PSQ items gave more information at higher levels of psychosis, with hypomania giving the least discriminating information. LIMITATIONS: Participants were recruited from general medical facilities, so findings may not be generalizable to the general population. CONCLUSION: The PSQ demonstrated a unidimensional factor structure in these samples. Items were measured equivalently across all study settings, suggesting that differences in prevalence of psychotic symptoms between countries were less likely to represent measurement artifact. The PSQ is more reliable in screening for psychosis in individuals with higher degrees of psychotic experiences-hypomania excluded-and might decrease the false-positive rate from mild nonspecific psychotic experiences.

Enhancing Discovery of Genetic Variants for Posttraumatic Stress Disorder Through Integration of Quantitative Phenotypes and Trauma Exposure Information.

BACKGROUND: Posttraumatic stress disorder (PTSD) is heritable and a potential consequence of exposure to traumatic stress. Evidence suggests that a quantitative approach to PTSD phenotype measurement and incorporation of lifetime trauma exposure (LTE) information could enhance the discovery power of PTSD genome-wide association studies (GWASs). METHODS: A GWAS on PTSD symptoms was performed in 51 cohorts followed by a fixed-effects meta-analysis (N = 182,199 European ancestry participants). A GWAS of LTE burden was performed in the UK Biobank cohort (N = 132,988). Genetic correlations were evaluated with linkage disequilibrium score regression. Multivariate analysis was performed using Multi-Trait Analysis of GWAS. Functional mapping and annotation of leading loci was performed with FUMA. Replication was evaluated using the Million Veteran Program GWAS of PTSD total symptoms. RESULTS: GWASs of PTSD symptoms and LTE burden identified 5 and 6 independent genome-wide significant loci, respectively. There was a 72% genetic correlation between PTSD and LTE. PTSD and LTE showed largely similar patterns of genetic correlation with other traits, albeit with some distinctions. Adjusting PTSD for LTE reduced PTSD heritability by 31%. Multivariate analysis of PTSD and LTE increased the effective sample size of the PTSD GWAS by 20% and identified 4 additional loci. Four of these 9 PTSD loci were independently replicated in the Million Veteran Program. CONCLUSIONS: Through using a quantitative trait measure of PTSD, we identified novel risk loci not previously identified using prior case-control analyses. PTSD and LTE have a high genetic overlap that can be leveraged to increase discovery power through multivariate methods.

Patterning of individual variability in neurocognitive health among South African women exposed to childhood maltreatment.

There are individual differences in health outcomes following exposure to childhood maltreatment, yet constant individual variance is often assumed in analyses. Among 286 Black, South African women, the association between childhood maltreatment and neurocognitive health, defined here as neurocognitive performance (NP), was first estimated assuming constant variance. Then, without assuming constant variance, we applied Goldstein's method (Encyclopedia of statistics in behavioral science, Wiley, 2005) to model "complex level-1 variation" in NP as a function of childhood maltreatment. Mean performance in some tests of information processing speed (Digit-symbol, Stroop Word, and Stroop Color) lowered with increasing severity of childhood maltreatment, without evidence of significant individual variation. Conversely, we found significant individual variation by severity of childhood maltreatment in tests of information processing speed (Trail Making Test) and executive function (Color Trails 2 and Stroop Color-Word), in the absence of mean differences. Exploratory results suggest that the presence of individual-level heterogeneity in neurocognitive performance among women exposed to childhood maltreatment warrants further exploration. The methods presented here may be used in a person-centered framework to better understand vulnerability to the toxic neurocognitive effects of childhood maltreatment at the individual level, ultimately informing personalized prevention and treatment.

Psychological resilience: an update on definitions, a critical appraisal, and research recommendations.

Background: The ability to resist adverse outcomes, or demonstrate resilience after exposure to trauma is a thriving field of study. Yet ongoing debate persists regarding definitions of resilience, generalizability of the extant literature, neurobiological correlates, and a consensus research agenda. Objectives: To address these pressing questions, Drs. Christy Denckla and Karestan Koenen (co-chairs) convened a multidisciplinary panel including Drs. Dante Cicchetti, Laura Kubzansky, Soraya Seedat, Martin Teicher, and David Williams at the 2019 annual meeting of the International Society for Traumatic Stress Studies (ISTSS). Questions included (1) how have definitions of resilience evolved, (2) what are the best approaches to capture the complexity of resilience processes, and (3) what are the most important areas for future research? Methods: The proceedings of this panel are summarized in this report, and prominent themes are synthesized and integrated. Results: While different definitions emerged, all shared a focus on conceptualizing resilience at multiple levels, from the biological to the social structural level, a focus on the dynamic nature of resilience, and a move away from conceptualizing resilience as only an individual trait. Critical areas for future research included 1) focused efforts to improve assessment that has international and cross-cultural validity, 2) developing within-study designs that employ more intensive phenotyping strategies, 3) examining outcomes across multiple levels and domains, and 4) integrating conceptualizations of resilience from the individual-level to the larger social context at the population health level. Conclusion: Increasingly sophisticated and nuanced conceptual frameworks, coupled with research leveraging advances in genetics, molecular biology, increased computational capacity, and larger, more diverse datasets suggest that the next decade of research could bring significant breakthroughs.

Antecedentes: La capacidad de los sujetos para resistirse a resultados adversos ­ o demostrar resiliencia ­ luego de la exposición al trauma es un campo de estudios creciente. Sin embargo, persiste el debate en las definiciones de resiliencia, en cuáles son sus sustratos neurobiológicos, en qué medida los hallazgos de la literatura existente pueden ser generalizados, y en la dirección que debe tomar la investigación futura.Objetivos: Para abordar estas preguntas urgentes los doctores Christy Denckla y Karestan Koen (copresidentes) convocaron un panel multidisciplinario que incluyó a los doctores Dante Cicchetti, Laura Kubzansky, Soraya Seedat, Martin Teicher y David Williams, en el encuentro anual de la Sociedad Internacional para los Estudios del Estrés Traumático (ISTSS por sus siglas en inglés) del 2019. Las preguntas incluyeron (1) cómo han evolucionado las definiciones de resiliencia, (2) cuáles son los mejores enfoques para capturar la complejidad de los procesos de resiliencia, y (3) ¿cuáles son las áreas más importantes para la investigación futura?Métodos: Las actas de este panel se resumen en este informe, y los temas destacados se sintetizan e integran.Resultados: Si bien surgieron diferentes definiciones, todas compartían el enfoque de conceptualizar la resiliencia en múltiples niveles, desde el nivel biológico hasta el nivel social estructural, el enfoque de la naturaleza dinámica de la resiliencia, y el dejar de conceptualizar la resiliencia como un rasgo individual. Las áreas álgidas de investigación a futuro incluyen 1) esfuerzos enfocados en mejorar la evaluación de la resiliencia con validación internacional e intercultural, 2) desarrollar diseños de estudio que utilicen estrategias de fenotipificación más intensivas, 3) evaluar los resultados a lo largo de múltiples niveles y dominios, y 4) integrar conceptualizaciones de la resiliencia desde el nivel individual hacia el contexto social en niveles de salud poblacionales.Conclusión: Los marcos conceptuales cada vez más sofisticados y matizados, junto con la investigación que aprovecha los avances en genética, biología molecular, mayor capacidad computacional y conjuntos de datos más grandes y diversos, sugieren que la próxima década de investigación podría traer importantes avances.

REACH for mental health in the COVID19 pandemic: an urgent call for public health action.

Chan de Salud Pública de Harvard.

Prevalence of parental bereavement among female sex workers (FSW) in Kibra, Kenya.

Female sex workers (FSW) residing in Kibra, Kenya experience elevated exposure to adverse events, yet the prevalence of parental bereavement is not well characterized. This cross-sectional pilot study on 301 FSWs residing in Kibra, Kenya found that 67.7% of these women were parentally bereaved. Significantly fewer parentally bereaved women reported historical use of condoms and emergency contraception compared to non-bereaved women, and older age of paternal bereavement was significantly associated with current contraceptive use. Prevalence rates of bereavement among this cohort are well over the national Kenyan average, and further research on the specific impact of bereavement is warranted.

Generalizability of demographically corrected Zambian neuropsychological norms to South African women.

Objective: Demographically corrected norms typically account for the effects of age, education, and in some cases, sex and other factors (e.g. race/ethnicity). However, generalizability of normative standards to different countries and ethnic groups is not universal. This study sought to determine whether demographically specific Zambian neuropsychological norms would generalize to a group of South African women.Method: 212 English-Xhosa bilingual, South African (SA) women were administered a comprehensive neuropsychological (NP) test battery in either English or Xhosa. We examined rates of "impairment" using Global Deficit Scores (GDS) based upon published, demographically corrected norms from a nearby African country (Zambia). Using multiple regression, we examined the extent to which Zambian norms "corrected" for the effects of age and education in this SA sample.Results: Compared to the normative standards from Zambia, the South African women performed somewhat worse than expected on a few test measures and better than expected on others, but their GDS and associated "impairment" rates were close to what was seen in Zambia. Demographically corrected Zambian norms adequately adjusted for the effects of age and years of education in this sample of SA women, with the exception that Zambian norms appeared to "under correct" for the positive effects of years of education on tests of information processing speed.Conclusions: Demographically corrected norms developed for Zambia may adequately adjust for the effects of age in SA women. Further research is needed to determine whether additional corrections for education are needed in SA, especially for tests of information processing speed.
