Assessing the Role of Spirituality in Coping Among African Americans Diagnosed with Cancer

Spirituality plays an important role in cancer coping among African Americans. The purpose of this study was to report on the initial psychometric properties of instruments specific to the cancer context, assessing the role of spirituality in coping. Items were developed based on a theoretical model of spirituality and qualitative patient interviews. The instruments reflected connections to self, others, God, and the world. One hundred African American cancer survivors completed the instruments by telephone. The instruments showed adequate internal reliability, mixed convergent validity, discriminant validity, and interpretable factor structures.     

A modified counterconditioning procedure prevents the renewal of conditioned fear in rats

Two studies using an ABA design examined the Extinction and renewal of conditioned barpress suppression. Following lights-off and foot shock pairings in Context A, rats were placed in Context B and were given either a standard counterconditioning procedure where the lights-off CS was paired with a novel food US delivered freely or a modified counterconditioning procedure where CS-US pairings only occurred if the rat earned the US by performing a required behavior during the CS. Results indicated that the modified counterconditioning procedure thwarted ABA renewal but the conventional counterconditioning procedure did not reduce ABA renewal any more than nonreinforced exposure to the CS alone. Furthermore, the response required during the modified counterconditioning procedure could be one used as a baseline response during Acquisition of fear or it could be a novel response. Implications of the results for theories of Extinction and renewal of fear are discussed.     

Assessing the Reliability of Situational Judgment Tests Used in High‐Stakes Situations

Assessing reliability of situational judgment tests (SJTs) in high‐stakes situations is problematic with reliability inappropriately measured by Cronbach's alpha when test items are heterogeneous. We computed the corrected, weighted mean alpha from 56 alpha coefficients, which produced a value of α = .46 and reviewed appropriate types of reliability to use with SJTs. In the current longitudinal study, SJT test–retest reliability was r = .82, compared with internal consistency, α = .46, and stratified alpha, α = .45 at Time 1 and α = .52 and stratified α = .51 at Time 2. We used a student sample (Time 1: n = 185; Time 2: n = 132) with items from a credentialing exam with ‘should do’ instructions. The SJT correlated significantly with cognitive ability, r = .30, and agreeableness, r = .24. In Study 2, we assessed test–retest reliability with Human Resource professionals (Time 1: n = 94; Time 2: n = 32) who had been recently credentialed and who participated in a pilot test of new SJT items with ‘most likely/least likely do’ response options. The SJT test–retest reliability was r = .66 compared with internal consistency, α = .43 and stratified α = .47 at Time 1 and α = .61 and stratified α = .67 at Time 2. We discuss the theoretical implications of the Study 1 results as well as the practical implications for use of SJTs in credentialing examinations.     

Social,Religious and Spiritual Capital and Physical/Emotional Functioning in a National Sample of African Americans

Spiritual and religious capital are forms of the broader construct of social capital. The present study, using probability‐based sampling methods, surveyed a national sample of African American adults to examine the relative contributions of spiritual and religious capital to their physical and emotional functioning. Analyses were conducted to determine if these constructs made a unique contribution above and beyond general social capital. African American men and women (N = 803) were interviewed by telephone. Hierarchical linear regressions revealed that, across the full sample, although social capital was a positive predictor of physical and emotional functioning (p < .05 and p < .001), neither religious nor spiritual capital made an additional contribution to these outcomes. However, the relationships among these variables differed for men and women. Among men, social capital predicted positive emotional functioning (p < .001) but not physical functioning; spiritual and religious capital made no additional contribution to either outcome variable. Among women, social capital predicted positive emotional functioning (p < .01) but not physical functioning. However, religious capital did make a significant additional contribution to the prediction of emotional functioning (ΔR², p < .01). Dividing the sample into different age groups did not produce any different findings from those found with the sample as a whole. Findings are discussed in terms of implications for church‐ and faith‐based health promotion interventions aimed at health disparities reduction. Copyright © 2011 John Wiley & Sons, Ltd.     

Environmental enrichment protects against the effects of chronic stress on cognitive and morphological measures of hippocampal integrity

Chronic stress has detrimental effects on hippocampal integrity, while environmental enrichment (EE) has beneficial effects when initiated early in development. In this study, we investigated whether EE initiated in adulthood would mitigate chronic stress effects on cognitive function and hippocampal neuronal architecture, when EE started one week before chronic stress began, or two weeks after chronic stress onset. Adult male Sprague Dawley rats were chronically restrained (6h/d) or assigned as non-stressed controls and subdivided into EE or non-EE housing. After restraint ended, rats were tested on a radial arm water maze (RAWM) for 2-d to assess spatial learning and memory. The first study showed that when EE began prior to 3-weeks of chronic stress, EE attenuated chronic stress-induced impairments in acquisition, which corresponded with the prevention of chronic stress-induced reductions in CA3 apical dendritic length. A second study showed that when EE began 2-weeks after the onset of a 5-week stress regimen, EE blocked chronic stress-induced impairments in acquisition and retention at 1-h and 24-h delays. RAWM performance corresponded with CA3 apical dendritic complexity. Moreover, rats in EE housing (control or stress) exhibited similar corticosterone profiles across weeks, which differed from the muted corticosterone response to restraint by the chronically stressed pair-housed rats. These data support the interpretation that chronic stress and EE may act on similar mechanisms within the hippocampus, and that manipulation of these factors may yield new directions for optimizing brain integrity and resilience under chronic stress or stress related neuropsychological disorders in the adult.     

Agonistic rank,aggression, social context,and testosterone in male pigtail monkeys

Two groups of pigtail monkeys were merged, a third was formed, and individual males were introduced into a group in a series of experiments examining the effects of social context upon agonistic rank, aggressive expression, and testosterone levels. In the first experiment, two heterosexual groups, containing adult males unfamiliar to the other group, were merged. The two groups fought, and the smaller group was defeated. The alpha and beta males of the defeated group were singled out for repeated attack and both showed significant drops in circulating levels of testosterone. Both males were removed from the group during the first day, but testosterone levels did not recover to baseline levels for several days. The alpha male of the victorious group, on the other hand, showed a significant rise in testosterone, which was apparent only on the day following the merger. In order to study the influence of previous social familiarity on male reception into a group, another group was formed by removing males from the victorious group and placing them in a separate enclosure. The males in the new group established a dominance hierarchy unrelated to their previous social ranks with one another. Three months later, each of the six adult males remaining in the parent group was individually introduced into the new group for one day or less. Each of the males introduced into the new group accepted a social position at the lower end of the dominance hierarchy without regard to his previous rank relationships with the host males when they were all in the parent group. Even the alpha and beta males of the parent group were relegated to low rank positions in the new group, despite having ranked over each of the host males since birth. In contrast to the aggression directed at the unfamiliar males in the first experiment, a minimum of aggression was directed to the familiar males introduced into the new group in the second experiment. Although the males introduced accepted low social ranks, it appeared that each was readily integrated into the group with a minimum of aggressive interaction during the time he was scheduled to remain in the group. There were no significant changes in circulating levels of testosterone in any of the males during the introductions of familiar males to one another.

Classification objects, ideal observers & generative models

A successful vision system must solve the problem of deriving geometrical information about three-dimensional objects from two-dimensional photometric input. The human visual system solves this problem with remarkable efficiency, and one challenge in vision research is to understand how neural representations of objects are formed and what visual information is used to form these representations. Ideal observer analysis has demonstrated the advantages of studying vision from the perspective of explicit generative models and a specified visual task, which divides the causes of image variations into the separate categories of signal and noise. Classification image techniques estimate the visual information used in a task from the properties of “noise” images that interact most strongly with the task. Both ideal observer analysis and classification image techniques rely on the assumption of a generative model. We show here how the ability of the classification image approach to understand how an observer uses visual information can be improved by matching the type and dimensionality of the model to that of the neural representation or internal template being studied. Because image variation in real world object tasks can arise from both geometrical shape and photometric (illumination or material) changes, a realistic image generation process should model geometry as well as intensity. A simple example is used to demonstrate what we refer to as a “classification object” approach to studying three-dimensional object representations.     

Teaching Mindfulness for the Self-Care and Well-Being of Counselors-in-Training

ABSTRACT

The demands and expectations placed on counselors-in-training can make them susceptible to stress, burnout, and poor school-life balance. Therefore, counseling students could benefit from learning mindfulness techniques as self-care strategies that promote increased relaxation, coping, and stress prevention. This mixed-methods study examined graduate counseling students’ perceptions of mindfulness training to determine its impact on self-efficacy, mood, stress, and other areas of wellness. Participants reported enhanced relaxation, increased awareness of the need for self-care, better understanding of the connection between mindfulness and overall well-being, and an impact of mindfulness on other areas of their lives.
