Mediation and Moderation: Testing Relationships Between Symptom Status,Functional Health,and Quality of Life in HIV Patients

Three demographic dimensions previously isolated by cluster analysis procedures (using BC TRY System computer analyses) were compared in different metropolitan areas for their stability over time and place. Also, the social areas discovered within the communities were studied for their stability over time and place. The three demographic dimensions (socio-economic independence, family life, and assimilation) accounted for the generality of 33 census tract (1940) characteristics in two communities. It was also shown that the three basic dimensions were essentially unchanged during the decade which included World War 11. The stability of these dimensions was retained even though there was considerable change in residents in each metropolitan area during the decade. The validity of cluster-search procedures is demonstrated by the stability of the three demographic dimensions.     

Development of the Significant Other Survey: An Interview for Family Members of Substance Users

The Significant Other Survey (SOS) is a semi-structured interview designed to measure the multidimensional problems experienced by family members with a substance abusing loved one. This article describes the development of the SOS and its psychometric properties based on data obtained from significant others of 110 substance abusing adults. Interrater and test-retest reliability estimates were within acceptable ranges, adequate internal consistency was demonstrated for six of seven problem domains, and the problem domains were low to moderately correlated with each other. Issues related to future instrument development and the utility of the SOS for both family practitioners and researchers are described.     

Differential brain shrinkage over 6 months shows limited association with cognitive practice

The brain shrinks with age, but the timing of this process and the extent of its malleability are unclear. We measured changes in regional brain volumes in younger (age 20–31) and older (age 65–80) adults twice over a 6 months period, and examined the association between changes in volume, history of hypertension, and cognitive training. Between two MRI scans, 49 participants underwent intensive practice in three cognitive domains for 100 consecutive days, whereas 23 control group members performed no laboratory cognitive tasks. Regional volumes of seven brain structures were measured manually and adjusted for intracranial volume. We observed significant mean shrinkage in the lateral prefrontal cortex, the hippocampus, the caudate nucleus, and the cerebellum, but no reliable mean change of the prefrontal white matter, orbital-frontal cortex, and the primary visual cortex. Individual differences in change were reliable in all regions. History of hypertension was associated with greater cerebellar shrinkage. The cerebellum was the only region in which significantly reduced shrinkage was apparent in the experimental group after completion of cognitive training. Thus, in healthy adults, differential brain shrinkage can be observed in a narrow time window, vascular risk may aggravate it, and intensive cognitive activity may have a limited effect on it.     

Religious Discrimination in the Workplace: A Review and Examination of Current and Future Trends

Purpose

Over the last decade, religious discrimination claims have risen more rapidly compared to most other protected categories under the Civil Rights Act (CRA). The goal of this review paper is to summarize the psychological and HR practitioner-focused research on religious discrimination as it relates to the CRA to understand these religious discrimination claims. In doing so, this review also highlights what future research is needed, and what the challenges and practical implications of religious discrimination are for managers.

Design/methodology/approach

We conduct a systematic literature review of the psychology and business research on religious discrimination.

Findings

Building from the literature review and case law, we highlight four trends that contribute to religious discrimination in the workplace: (1) legal ambiguities, (2) increased religious diversity in the American workforce, (3) increasing expression of religious beliefs, and (4) the unique nature of religion.

Implications

The trends identified in our review paper highlight the need for employers to understand and address religious discrimination issues in the workplace and the lack of empirical research in this area points to a critical gap in our understanding of workplace religious discrimination that warrants future research.

Originality/value

In addition to highlighting trends that contribute to religious discrimination in the workplace, this literature review addresses where there are gaps in the existing research that call for further research and offers practical implications for employers and organizations.     

SHS-Related Pediatric Sick Visits are Linked to Maternal Depressive Symptoms Among Low-Income African American Smokers: Opportunity for Intervention in Pediatrics

Maternal smoking and depressive symptoms are independently linked to poor child health outcomes. However, little is known about factors that may predict maternal depressive symptoms among low-income, African American maternal smokers—an understudied population with children known to have increased morbidity and mortality risks. The objective of this study was to test the hypothesis that secondhand smoke exposure (SHSe)-related pediatric sick visits are associated with significant maternal depressive symptoms among low-income, African American maternal smokers in the context of other depression-related factors. Prior to randomization in a behavioral counseling trial to reduce child SHSe, 307 maternal smokers in Philadelphia completed the Center for Epidemiologic Studies Depression (CES-D) and questionnaires measuring stressful events, nicotine dependence, social support, child health and demographics. CES-D was dichotomized at the clinical cutoff to differentiate mothers with significant versus low depressive symptoms. Results from direct entry logistic regression demonstrated that maternal smokers reporting more than one SHSe-related sick visit (OR 1.38, p < .001), greater perceived life stress (OR 1.05, p < .001) and less social support (OR 0.82, p < .001) within the last 3 months were more likely to report significant depressive symptoms than mothers with fewer clinic visits, less stress, and greater social support. These results suggest opportunities for future hypothesis-driven evaluation, and exploration of intervention strategies in pediatric primary care. Maternal depression, smoking and child illness may present as a reciprocally-determined phenomenon that points to the potential utility of treating one chronic maternal condition to facilitate change in the other chronic condition, regardless of which primary presenting problem is addressed. Future longitudinal research could attempt to confirm this hypothesis.     

Race differences in psychopathology and disparities in treatment seeking: Community and jail-based treatment seeking patterns

Whites in community samples utilize mental health services at a much higher rate than African Americans (Kessler, et al., 2005). Is this also the case among those in jails? In this study of jail inmates (229 African American, 185 White) there were no race difference in the overall need for mental health treatment (63% of participants had significant symptoms on the Personality Assessment Inventory) but race differences in the level and types of symptoms were evident. Additionally, while Whites were more likely to report pre-incarceration treatment there were no differences in treatment seeking or access to mental health programs while in jail, implying that if barriers to treatment in the community were removed (cost/insurance, location/transportation, time) racial disparities in treatment utilization may be reduced.     

Drawing the Eczema Aesthetic: The Psychological Effects of Chronic Skin Disease as Depicted in the Works of John Updike, Elizabeth Bishop, and Zelda Fitzgerald

How might the psycho-social effects of chronic skin disease, its treatments (and discontents) be figuratively expressed in writing and painting? Does the art reveal common denominators in experience and representation? If so, how do we understand the cryptic language of these expressions? By examining the works of artists with chronic skin diseases—John Updike, Elizabeth Bishop, and Zelda Fitzgerald—some common features can be noted. Chronically broken skin can fracture the ego or self-perception, resulting in a disturbed body image, which leads to personality disorders and co-morbid affective disorders such as anxiety and depression. The vertiginous feeling that results can be noted in the paradoxical characters, figures, and psyches portrayed in the works of these artists. This essay will examine the more specific ways in which artists disclose and/or conceal their experiences and the particular ways in which these manifest in their works. While certain nuances exist, the common denominators give us a starting point for developing an eczema aesthetic, a code for interpreting the ways in which artists’ experiences with skin disease manifest in their works.     

Virtual-reality distraction and cold-pressor pain tolerance: does avatar point of view matter?

This study tested the effects of distraction using virtual-reality (VR) technology on acute pain tolerance in young adults. Forty-one undergraduate students, aged 18-23 years, used a VR head-mounted display helmet, steering wheel, and foot pedal to play an auto racing video game while undergoing exposure to very cold water (cold pressor set at 1 °C). Two different game views were tested that were hypothesized to affect the degree to which participants felt "present" in the virtual environment: a first-person view, in which the participant saw the virtual environment through the eyes of the game character being manipulated; and a third-person view, in which the participant viewed the game character from a distance. The length of time participants tolerated the cold-water exposure (pain tolerance) under each distraction condition was compared to a baseline (no distraction) trial. Subjects also rated the degree to which they felt "present" in the virtual environment after each distraction trial. Results demonstrated that participants had significantly higher pain tolerance during both VR-distraction conditions relative to baseline (no distraction) trials. Although participants reported a greater sense of presence during the first-person condition than the third-person condition, pain-tolerance scores associated with the two distraction conditions did not differ. The types of VR applications in which presence may be more or less important are discussed.     

EFFECTS OF RESPONSE SPACING ON ACQUISITION AND RETENTION OF CONDITIONAL DISCRIMINATIONS

Pigeons were exposed to a repeated acquisition procedure in which no delays were imposed and rate of responding was relatively high. They also were exposed to conditions in which delays were arranged between trials within chains or between completed chains, and rates of responding were lower. Number of trials, rate of reinforcement, difficulty of the discrimination, and motivating operations were held constant. Terminal accuracy was highest under the no‐delay condition, in which rate of responding was highest. Effects of trial spacing on retention were mixed and depended on whether delays were imposed between trials within chains or between completed chains. These findings provide basic‐research support for the rapid presentation of trials in direct instruction and for rate building in precision teaching.
