Ad libitum dehydration is associated with poorer performance on a sustained attention task but not other measures of cognitive performance among middle‐to‐older aged community‐dwelling adults
OBJECTIVE: Hydration status and water intake are critical to physiological health. Despite a popular narrative that dehydration impairs cognitive performance, results are mixed in the literature. Therefore, we tested how hydration status was associated with cognitive performance in an ad libitum state over the course of 3 months. METHODS: Data come from a short-term longitudinal study among middle-to-older aged US adults (n = 78) measured three t…
High Heart Rate Variability Buffers the Effect of Attachment Insecurity on Sleep Quality
OBJECTIVE: Sleep quality is an important health-protective factor. Psychosocial factors, including attachment orientation, may be valuable for understanding who is at risk of poor sleep quality and associated adverse health outcomes. High attachment anxiety is reliably associated with adverse health outcomes, whereas high attachment avoidance is associated with adverse health outcomes when co-occurring with poor self-regulatory capacity, indexed …
Diminished Cellular Immunity and Executive Cognitive Functioning Among Middle-Aged and Elderly Adults
OBJECTIVE: Within the field of psychoneuroimmunology, much attention has been given to immune dysregulation and its impact on cognitive functioning. Some of this work has focused on the association between high levels of basal proinflammatory cytokines and poorer performance on measures of executive functioning; however, effect sizes have been quite small in human studies. METHODS: We investigated whether Epstein-Barr virus (EBV) antibody titers,…
Links Between Socioeconomic Status, Daily Depressive Affect, Diurnal Cortisol Patterns, and All-Cause Mortality
OBJECTIVE: Socioeconomic status (SES) remains a robust risk factor for mortality. Various theoretical models postulate that lower SES is associated with higher negative affect, which then initiates a cascade of physiological disturbances that contribute to illness and early mortality. However, few studies have explicitly investigated the interplay between psychological and biological factors in determining SES disparities in mortality. This study…
Emotion Regulation and Immune Functioning During Grief
OBJECTIVE: Losing a spouse is a distressing life event that can negatively affect both mental and physical health. Stress-induced health consequences often include increased risk of cardiovascular disease and altered immune system functioning marked by increased inflammation. Here, we sought to identify individual difference factors that covary with problematic inflammatory outcomes. METHOD: We measured recently bereaved spouses' (n = 99) propens…
Relationship satisfaction determines the association between Epstein–Barr virus latency and somatic symptoms after the loss of a spouse
The loss of a spouse is associated with a host of negative health outcomes. While bereaved individuals commonly report somatic symptoms, no investigations exist of the association between reactivation of latent Epstein–Barr virus (EBV) and somatic symptoms among this population. Further, how an individual perceives the quality of their lost relationship in retrospect may impact loss outcomes. Among 99 bereaved spouses, elevated EBV antibody titer…
Church attendance and CMV herpes virus latency among bereaved and non-bereaved adults
OBJECTIVE: There is widespread literature linking church attendance to physical health. However, little is known about the association of church attendance and the immune system, particularly during difficult life transitions. This study investigated the association between church attendance and CMV herpes-virus latency by assessing Cytomegalovirus (CMV) IgG antibody titers among bereaved and non-bereaved individuals. METHODS: Participants includ…
Differential psychological reactions to grief
Childhood maltreatment dysregulates an individual's physiological response to stress, increasing reactivity to stressors across the lifespan. Given the prevalence and impact of bereavement, we examined whether the association between childhood maltreatment and depression was exacerbated by spousal bereavement. We identified an interaction between childhood maltreatment and bereavement using linear regression analysis ( B = 0.79, p B = 0.86, p B =…
An Evaluation of Perceived Health Risk and Depressive Symptoms Before a Disaster in Predicting Postdisaster Inflammation
OBJECTIVE: Exposure to major life stressors is associated with subsequent enhanced inflammation-related disease processes. Depressive symptoms exacerbate stress-induced inflammatory responses. Moreover, those who report a high degree of perceived health risk before being exposed to a major life stressor such as a disaster are at risk for poor health outcomes. The present study examined whether perceived health risk and depressive symptoms before …
The utility of patient-reported outcome measures among patients with myalgic encephalomyelitis/chronic fatigue syndrome
Integrating and differentiating aspects of self-regulation
Subdisciplines within psychology frequently examine self-regulation from different frameworks despite conceptually similar definitions of constructs. In the current study, similarities and differences between effortful control, based on the psychobiological model of temperament (Rothbart, Derryberry, & Posner, 1994), and executive functioning are examined and empirically tested in three studies (n = 509). Structural equation modeling indicated th…
An examination of parental self-efficacy among mothers and fathers
Sevigny and Loutzenhiser, in their 2010 examination of parental self-efficacy (PSE) in fathers, did not identify data supporting the importance of self-efficacy beliefs in the paternal parenting role. However, a task-specific measure of PSE was used, and because the tasks mothers and fathers typically perform differ, task-specific measures may not be applicable to both mothers and fathers. The present study addressed this limitation by using a do…
Predictors of romantic relationship formation
This prospective study (N = 90) investigated the early formation of romantic relationships within an attachment-theoretical framework. Specifically, it tested whether general attachment to romantic partners was predictive of single individuals' progressing from not dating to dating and from not dating or casual dating to a committed and exclusive relationship when simultaneously considering desire for starting a committed relationship, prior dati…
