A group comparison of those with hypertension and other chronic illness: A factor and item level analysis of anger and hostility

Abstract

A considerable body of research has suggested that essential hypertension is related to both expressed anger and suppressed hostility. This study suggests and provides some evidence that these reported results may simply have arisen as the result of a lack of proper statistical control and differential item functioning across the items on which the measures were based. Three groups of respondents were selected (a) those diagnosed as having hypertension (b) a group who admitted to having a chronic medical condition unrelated to hypertension and (c) individuals who did not have a chronic medical condition. A confirmatory factor model was used to test the structure of a measure of expressed anger and suppressed hostility. Differences were then examined across the three conditions at both the factor and item levels within a MIMIC structure and controlling for age and gender. Differential effects were found between females and males on two observed measures of expressed anger. Age had a direct effect on both the measure of expressed anger and suppressed hostility. After the effects of age and gender were controlled, no statistically significant group differences were found. Previous results indicating a difference on expressed anger and suppressed hostility may, as in the present analysis, be put down to a combination of lack of appropriate statistical control, and to ignoring the differential pattern of responding across the observed measures.     

Clamped Corticosterone (B) Reveals the Effect of Endogenous B on Both Facilitated Responsivity to Acute Restraint and Metabolic Responses to Chronic Stress

To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.     

Prevalence and predictors of benevolent childhood experiences among a representative sample of young people

Emerging research evidence suggests that benevolent childhood experiences (BCEs) may partly explain more favourable mental health outcomes among individuals affected by adverse childhood experiences (ACEs). However, much of this research has focused on adult populations. Consequently, this study sought to provide the first rigorous assessment of the prevalence and predictors of BCEs using a nationally representative sample of young people from Northern Ireland (NI). Participants were 11–19-years-olds (N = 1293) who participated in the NI Youth Wellbeing Prevalence Survey (NI-YWS, 2020). Prevalence rates, gender differences and predictors of BCEs were investigated. Results revealed how most of the sample experienced multiple BCEs (95%, n = 1084), with females reporting higher levels of BCEs. Significant positive predictors of BCEs were female gender, parental education, living with both biological parents, and living in areas with lower deprivation, while significant negative predictors of BCEs included family being in receipt of social welfare and older age. Overall, this study highlights how BCEs are common, while the identification of factors associated with likelihood of having positive experiences during early development provides novel insights into those young people who may be at greater risk for maladaptive psychological outcomes.     

New approaches to the ‘crucial’ test of the causation and selection hypotheses in a Northern Irish sample

This paper examines the relationship between minority/majority status and psychological adjustment, as measured by the GHQ‐12. Rather than using religious labels in Northern Ireland to define minority/majority status, the authors hypothesized that such status is more contingent upon the local area context. Using a purer operationalization of minority/majority status, the authors found no evidence of an ‘ethnic density effect’. Implications for the questionable validity of the ‘crucial test’ of the selection and causation hypotheses are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

The cocktail party phenomenon revisited: the importance of working memory capacity

Wood and Cowan (1995) replicated and extended Moray’s (1959) investigation of thecocktail party phenomenon, which refers to a situation in which one can attend to only part of a noisy environment, yet highly pertinent stimuli such as one’s own name can suddenly capture attention. Both of these previous investigations have shown that approximately 33% of subjects report hearing their own name in an unattended, irrelevant message. Here we show that subjects who detect their name in the irrelevant message have relatively low working-memory capacities, suggesting that they have difficulty blocking out, or inhibiting, distracting information.     

Alternatives to switch-cost scoring in the task-switching paradigm: Their reliability and increased validity

In the task-switching paradigm, the latency switch-cost score—the difference in mean reaction time between switch and nonswitch trials—is the traditional measure of task-switching ability. However, this score does not reflect accuracy, where switch costs may also emerge. In two experiments that varied in response deadlines (unlimited vs. limited time), we evaluated the measurement properties of two traditional switch-cost scoring methods (the latency switch-cost score and the accuracy switch-cost score) and three alternatives (a rate residual score, a bin score, and an inverse efficiency score). Scores from the rate residual, bin score, and inverse efficiency methods had comparable reliability for latency switch-cost scores without response deadlines but were more reliable than latency switch-cost scores when higher error rates were induced with a response deadline. All three alternative scoring methods appropriately accounted for differences in accuracy switch costs when higher error rates were induced, whereas pure latency switch-cost scores did not. Critically, only the rate residual and bin score methods were more valid indicators of task-switching ability; they demonstrated stronger relationships with performance on an independent measure of executive functioning (the antisaccade analogue task), and they allowed the detection of larger effect sizes when examining within-task congruency effects. All of the three alternative scoring methods provide researchers with a better measure of task-switching ability than do traditional scoring methods, because they each simultaneously account for latency and accuracy costs. Overall, the three alternative scoring methods were all superior to the traditional latency switch-cost scoring method, but the strongest methods were the rate residual and bin score methods.     

Working memory and second language comprehension and production: A meta-analysis

Although working memory (WM) figures centrally in many theories of second language (L2) proficiency development and processing, some have argued that the importance of WM is overstated (e.g., Juffs, Transactions of the Philological Society, 102, 199–225, 2004). Despite many studies over the past two decades, the literature lacks a quantitative synthesis of the extant results. In this article, we report a meta-analysis of data from 79 samples involving 3,707 participants providing 748 effect sizes. The results indicate that WM is positively associated with both L2 processing and proficiency outcomes, with an estimated population effect size (ρ) of .255. In additional analyses, we assessed whether the WM–criterion relationship was modulated by potential covariates identified in the literature search (i.e., participant characteristics, WM measure features, criterion measure factors, and publication status). The results of the covariate analyses indicated larger effect sizes for the executive control (vs. storage) component of WM, and for verbal (vs. nonverbal) measures of WM. Minimal publication bias was detected, suggesting that WM has a robust, positive relationship with L2 outcomes. We discuss the implications of these results for models of WM and theories of L2 processing and L2 proficiency development.     

Death Anxiety Among University Students in Northern Ireland and Canada

Male and female university students in Northern Ireland (n = 315) and Canada (n = 255) completed Templer's Death Anxiety Scale (DAS) and the Taylor Manifest Anxiety Scale (MAS). Results of a discriminant function analysis indicated that Canadian students showed more concern about being afraid to die and thoughts of death, while students from the North of Ireland were more concerned about getting cancer, the shortness of life, and the viewing of a corpse. However, total DAS scores failed to show significance between group differences (p >.10). Correlations between DAS and MAS total scores were r =.34 for Northern Ireland and r =.31 for Canadian students.     

The deployment of attention in short-term memory tasks: Trade-offs between immediate and delayed deployment

Memory at times depends on attention, as when attention is used to encode incoming, serial verbal information. When encoding and rehearsal are difficult or when attention is divided during list presentation, more attention is needed in the time following the presentation and just preceding the response. Across 12 experimental conditions observed in several experiments, we demonstrated this by introducing a nonverbal task with three levels of effort (no task, a natural nonverbal task, or an unnatural version of the task) during a brief retention interval in a short-term digit recall task. Interference from the task during the retention interval was greater when resources were drawn away from the encoding of the stimuli by other factors, including unpredictability of the end point of the list, rapid presentation, and a secondary task during list presentation. When those conditions complicate encoding of the list, we argue, attention is needed after the list so that the contents of passive memory (i.e., postcategorical phonological storage and/or precategorical sensory memory) may be retrieved and become the focus of attention for recall.
