Obsessive-Compulsive Disorder in Late Life

Although obsessive-compulsive disorder (OCD) has received increasing attention, the study and treatment of OCD in late life has been neglected. The obsessions and compulsions seen with older adults do not appear to differ from the symptoms experienced by other age groups, although developmental issues might influence symptom focus (e.g., memory functioning-related obsessions). Hoarding difficulties might be prevalent in late life, although additional studies are needed. Seniors with OCD can present with comorbid psychiatric disorders, multiple general medical problems, and impaired cognitive functioning, complicating evaluation. There have not been controlled clinical trials of cognitive-behavioral therapy (CBT) for late-life OCD, although initial reports suggest older adults respond to CBT that includes age-related treatment modifications. We illustrate the challenges to assessing and treating older adults with OCD with case examples involving memory-related obsessions and clinical hoarding. The successful strategies used for adapting CBT for the treatment of late-life generalized anxiety disorder might serve as a model for advancing the study and treatment of late-life OCD.     

Subliminal understanding of negation: Unconscious control by subliminal processing of word pairs

A series of five experiments investigated the extent of subliminal processing of negation. Participants were presented with a subliminal instruction to either pick or not pick an accompanying noun, followed by a choice of two nouns. By employing subjective measures to determine individual thresholds of subliminal priming, the results of these studies indicated that participants were able to identify the correct noun of the pair – even when the correct noun was specified by negation. Furthermore, using a grey-scale contrast method of masking, Experiment 5 confirmed that these priming effects were evidenced in the absence of partial awareness, and without the effect being attributed to the retrieval of stimulus–response links established during conscious rehearsal.     

The Draw-A-Person Test and Process-Reactive Schizophrenia

The Draw-A-Pcrson test was administered to three matched groups of 32 male Ss each: reactive schizophrenics, process schizophrenics, and normal control subjects. Patients were rated for prognosis using the Premorbid Subscale of the Phillips Scale. Drawings were rated by two judges on 80 diagnostic signs culled from the literature. No signs were found to significantly differentiate reactive and process schizophrenics, and only three signs significantly differentiated normals from schizophrenics. It was concluded that a sign approach to the DAP is insensitive to the reaction-process dimension of schizophrenia, and of only limited value in differentiating between normals and schizophrenics in general.     

The black community's reactions to the 1992 los angeles riot

This article is based on field (street) interviews with a sample of 227 black community members living and/or working in South Central Los Angeles at the time of the 1992 riot. The interview instrument comprises 20 questions designed to (1) ascertain the reactions and feelings of black community members to the riot; and (2) compare a sample of black participants in the riot with nonparticipants. The participant group was found to be more frequently younger males with less education and lower income, and they were more likely to have arrest records prior to the riot than nonparticipants. Though reactions and feelings were mixed and contradictory, both groups reported an overall acceptance of the disorders. Differentials in reactions were in degree rather than in kind. Most objected to the riot in principle but concluded that collective violence “pays off.” The preriot structural facilitators (poverty, relative deprivation, unemployment, police brutality, racial discrimination, and negative police‐community relations) were similar to those found in the riot literature. Whatever the participants’ reasons and justifications for rioting might be, they present themselves as worthy protesters and freedom fighters. Unless their message is heeded and acted upon by ameliorating their adverse social, economic, and political conditions, similar riots are likely to occur.     

Individual strategies and release site features determine the extent of deviation in clock-shifted pigeons at familiar sites

When homing from familiar areas, homing pigeons are able to exploit previously acquired topographical information, but the mechanisms behind this ability are still poorly understood. One possibility is that they recall the familiar release site topographical features in association with the home direction (site-specific compass orientation strategy), another that the spatial relationships among landmarks guide their route home (piloting strategy), without relying on the compass mechanism. The two strategies can be put in conflict by releasing clock-shifted birds at familiar locations, in order to highlight which is preferred. We analysed GPS tracks of clock-shifted pigeons, with familiarity controlled at each of three different release sites, and we observed that pigeons can display individual preferences for one of the two orientation strategies and that some characteristic features of the release site have an important role in determining the level of landmark-based homeward orientation.     

Carrying the Burden: Perspectives of African American Pastors on Peer Support for People with Cancer

For African Americans facing advanced cancer, churches are trusted sources of support and ideal settings to improve access to supportive care. The Support Team model enhances community support for practical, emotional, and spiritual caregiving. We report on focus groups with pastors of 23 Black Churches and explore their perspective on the Support Team model for church members with cancer. Pastors describe the needs of church members facing cancer from a holistic perspective and recognize opportunities for synergistic faith–health collaboration. The results of this study indicate potential benefits of the Support Team model in Black Churches to reduce silent suffering among individuals facing cancer.     

Peer support critical elements and experiences in supporting the homeless: A qualitative study

Peer supporters are individuals with lived experience and are an integral part of health care systems, providing support to those affected by various phenomena such as homelessness and addictions. However, little is known about the critical elements that underpin peer support interventions. This qualitative study sought to understand the critical elements of intentional peer support with a homeless population, voiced by those who provide and/or receive this support. Twenty‐nine participants from 4 different homeless charities in England were interviewed about their experiences of providing/receiving peer support and what they felt were critical factors to its success. Participants defined peer support as an experience‐based relationship, built upon mutual understanding, empathy, and support. Thematic analysis was utilised to in developing 6 themes. Results identified peers' persistence in developing unique experience‐based relationships, providing social support, role modelling recovery, and peers' motivations were perceived as important factors involved in peer support. It was also found that peers described benefitting from helping, such as, undergoing transformative identity developments that helped them to escape homelessness. Through the retelling of their stories, they create meaning and restructure their autobiography, attributing experiences of homelessness as a catalyst for positive changes in their lives. Limitations and future research are discussed.     

Micro-mechanical measurements of fracture toughness of bismuth embrittled copper grain boundaries

Measuring the fracture properties of single grain boundaries has until now required macroscopic bi-crystals which are expensive and not always available. We describe a method for fracture testing using micro-cantilevers, manufactured using focussed ion beam machining and tested using a nanoindenter. We have used the method to measure the fracture toughness of selected grain boundaries in bismuth-embrittled copper. This technique is applicable to grain boundaries in other brittle polycrystalline samples for which large bi-crystals cannot be produced for conventional testing.
