Posttraumatic Stress Disorder and Handgrip Strength Among World Trade Center Firefighters and Emergency Medical Responders
Posttraumatic stress disorder (PTSD) has been linked to impaired physical function, which in turn predicts falls, morbidity, and mortality. However, few studies have used objective measures such as handgrip strength to assess physical function. In this cross-sectional study, we investigated associations of average PTSD symptom severity and symptom domain severity with measures of maximum handgrip strength and handgrip asymmetry from 11/2021–12/20…
Cumulative social advantage across the lifespan
This study introduces the concept of cumulative social advantage as a hierarchical construct encompassing multiple aspects of social connection, including religious, psychosocial, familial, and emotional dimensions. Using data from the Midlife Development in the United States-II ( n = 4,028) and Refresher ( n = 2,586) cohorts, we assessed the dimensionality, replicability, measurement invariance, and validity of a hierarchical model. Results supp…
Associations Between Loneliness, Epigenetic Aging, and Multimorbidity Through Older Adulthood
These results suggest that the impact of loneliness on multimorbidity may, in part, operate through DNA methylation. The specific intermediary, physiological mechanisms that are involved will require further research, but EAA measures like GrimAge are promising in helping to understand the health impacts of loneliness
Inter-cohort shifts in chronic disease, dementia, and mortality
18,528). In addition to exploring shifts in disease incidence we also examine shifts in disease mortality. Both general and sex-related differences are examined. Disease incidence has increased for later-born cohorts in England, replicating similar trends in the U.S. Not all diseases showed differences between men and women, but when differences were identified, women had lower risks for disease. In comparison to the U.S. sample, disease trends i…
Associations between epigenetic age acceleration and longitudinal measures of psychosocioeconomic stress and status
A novel approach to model cumulative stress
Comparing associations between personality and loneliness at midlife across three cultural groups
OBJECTIVE: Loneliness represents a public health threat given its central role in predicting adverse mental and physical health outcomes. Prior research has established four of the Big Five personality traits as consistent cross-sectional predictors of loneliness in largely western, White samples. However, it is not clear if the personality predictors of loneliness vary across cultures. METHOD: The present study estimates associations between the…
Cohort Changes and Sex Differences After Age 50 in Cognitive Variables in the English Longitudinal Study of Ageing
These cohort effects generally favored later-born cohorts. Implications and future directions are discussed
A Mixed‐Methods Approach to Refining and Measuring the Construct of Positive Risk‐Taking in Adolescence
Adolescence is a peak period for risk-taking, but research has largely overlooked positive manifestations of adolescent risk-taking due to ambiguity regarding operationalization and measurement of positive risk-taking. We address this limitation using a mixed-methods approach. We elicited free responses from contemporary college students (N = 74, M age = 20.1 years) describing a time they took a risk. Qualitative analysis informed the constructio…

The Association of Posttraumatic Stress Disorder With Longitudinal Change in Glomerular Filtration Rate in World Trade Center Responders
OBJECTIVE: High levels of psychological distress increase the risk of a wide range of medical diseases. In this study, we investigated the association between posttraumatic stress disorder (PTSD) and kidney disease. METHODS: World Trade Center (WTC) responders were included if they had two or more measures of estimated glomerular filtration rate (eGFR). The PTSD Checklist (PCL) was used to define no PTSD (PCL < 40), "mild" PTSD (40 ≤ PCL <50), an…
Stability and well‐being
OBJECTIVE: The present study estimates associations of the Big Five domains and their metatraits with individual indicators of eudaimonic, hedonic, and social well-being, as well as broader factors that capture the tendency for these individual indicators to correlate. METHOD: Using data from a large sample of adults from the United States, confirmatory factor analysis and exploratory structural equation modeling was used to verify the factor str…
Cohort and Period Effects as Explanations for Declining Dementia Trends and Cognitive Aging
Studies have reported that the age-adjusted incidence of cognitive impairment and dementia have decreased over the past two decades. Aging is the predominant risk factor for Alzheimer's disease and related dementias and for neurocognitive decline. However, aging alone cannot explain changes in the overall age-adjusted incidence of dementia. The objective of this position paper was to describe the potential for cohort and period effects in cogniti…

Demographic correlates of inflammatory and antiviral gene expression in the study of Midlife in the United States (Midus)
composite scores and empirically derived co-regulatory gene sets. For both composite scores and co-regulatory gene sets, White/European Americans showed lower while Black/African Americans showed higher expression of genes involved in interferon responses and antibody synthesis. The effects of chronological age on gene expression varied by sex, such that pro-inflammatory gene expression increased with age more rapidly for females than males. The …
Social-relational exposures and well-being
Kids becoming less alike
Recent work in personality development has indicated that the magnitude of individual differences in personality increases over child development. Do such patterns reflect the differentiation of individuals by genotype, an increasing influence of environmental factors, or some (interactive) combination of the two? Using a population-based sample of over 2,500 twins and multiples from the Texas Twin Project, we estimated age trends in the variance…
Genetic and environmental influences on internalizing psychopathology across age and pubertal development
Symptoms of anxiety and depression are commonly comorbid and partially share a genetic etiology. Mean levels of anxiety and depression increase over the transition to adolescence, particularly in girls, suggesting a possible role of pubertal development in the activation of underlying genetic risks. The current study examined how genetic and environmental influences on anxiety and depression differed by chronological age and pubertal status. We a…
Developmental differences in reward sensitivity and sensation seeking in adolescence
Sensation seeking has been found to increase, on average, from childhood to adolescence. Developmental scientists have hypothesized that this change could be driven by the rise of gonadal hormones at puberty, which affect reward-related processing in the brain. In a large, age-heterogeneous, population-based sample of adolescents and young adults (N = 810; ages 13-20 years), we tested for sex-specific associations between age, self-reported puber…
Genetically-mediated associations between measures of childhood character and academic achievement
Researchers and the general public have become increasingly intrigued by the roles that systematic tendencies toward thinking, feeling, and behaving might play in academic achievement. Some measures of constructs belonging to this group have been well studied in genetics and psychometrics, while much less is known about measures of other such constructs. The current study focuses on 7 character traits prominently featured in influential intervent…

The Need for Research on the Communication of Research Results
Research on problems of human relations differs from research in most other fields of science in a very important respect. In most fields of science it is not necessary for administrators or executives to have a comprehensive understanding of the research in order to utilize the results. All that has to be known is that the research has yielded a better method or a better product. Approval to substitute the new for the old can then be given. But …
