Optimism, Health Locus of Control, and Quality of Life  of Women with Initial versus Recurrent Breast Cancer (open access)

Optimism, Health Locus of Control, and Quality of Life of Women with Initial versus Recurrent Breast Cancer

Health Locus of Control (HLOC) and other predictors of Quality of Life (QL) were examined for women with an initial versus recurrent breast cancer diagnosis. Twenty-eight women with an initial breast cancer (IBC) diagnoses and twenty-eight women with recurrent breast cancer (RBC) diagnoses were recruited from doctors' offices and cancer support groups. Correlational analyses were used to assess the relationships between variables. No significant differences were found between women with IBC and RBC on Psychological QL. Doctor HLOC and Psychological QL were related for women with RBC (r = .481, p = .01) and marginally so for women with IBC (r = .329, p = .09). A positive correlation was also found between Doctor HLOC and Functional QL for both women with IBC (r = .464, p = .01) and women with RBC (r = .390, p = .04). After controlling for stage of cancer, women with RBC reported higher Functional QL than did women with IBC. Advanced (stages III or IV) versus early (stages I or II) cancer stage related to lower Functional QL, controlling for initial versus recurrent diagnosis (r = -.283, p = .01). A marginally significant relationship was also found for cancer stage, regardless of initial …

The Relationship Between Neuropsychological Performance and Daily Functioning in Individuals with Alzheimer's Disease (open access)

The Relationship Between Neuropsychological Performance and Daily Functioning in Individuals with Alzheimer's Disease

The results of neuropsychological tests are often used by clinicians to make important decisions regarding a demented patient's ability to competently and/or independently perform activities of daily living. However, the ecological validity of most neuropsychological instruments has yet to be adequately established. The current study examined the relationship between neuropsychological test performance and functional status in 42 individuals diagnosed with Alzheimer's Disease. A comprehensive battery of cognitive tests was employed in order to assess a wide range of neuropsychological abilities. Functional status was measured through the use of both a performance-based scale of activities of daily living (The Direct Assessment of Functional Status; Loewenstein et al., 1989) as well as by a caregiver/informant-based rating scale (Instrumental Activities of Daily Living; Lawton & Brody, 1969). Findings suggest that neuropsychological functioning is moderately predictive of functional status. Memory performance was the best predictor of functional status in most ADL domains, followed by executive functioning and visuospatial abilities.

Comparative Models of the Impact of Social Support on Psychological Distress in Cancer Patients (open access)

Comparative Models of the Impact of Social Support on Psychological Distress in Cancer Patients

This study tested the relationship between Social Support, Psychological Distress, and Illness Stress in individuals who report cancer as a health condition. This study was based on archival data obtained from the Wave 1 of the Health and Retirement Study (HRS). The HRS provides a nationally representative sample of individuals aged 51 to 61 in 1992 and their spouses. The study sample was limited to cancer patients with a spouse or partner (n = 503). A structural equation modeling analysis procedure was used to test the theoretical models. Measures of social support were limited to variables assessing the participant's satisfaction with social support. Evidence was found for the Stress Prevention and the Support Deterioration models. This is congruent with previous research using measures of social support perception. Both the Stress Prevention and the Support Deterioration models predict a negative relationship between Illness Stress and Social Support. In addition, a univariate analysis of variance was used to test the stress buffering model. Similarly to other studies measuring the individual's degree of integration, or its perception, in the social network, the present research supported the only the Main Effect model and not the Stress Buffering model.

Effects of Cautioning and Education in the Detection of Malingered Mild Traumatic Brain Injury (open access)

Effects of Cautioning and Education in the Detection of Malingered Mild Traumatic Brain Injury

This study examined the effectiveness of cautioning and education on simulating a mild traumatic brain injury on several neuropsychological measures. The measures used included the Word Memory Test (WMT), Wechsler Adult Intelligence Scales® - Third Edition (WAIS®-III), Wechsler Memory Scales®-3rd Edition instrument (WMS®-III), 16-item version of the Rey Memory Test, and a self-report symptom checklist. Five experimental groups were used including clinical and non-clinical controls, as well as three simulation groups. The design and implementation of this study also attempted to correct several methodological short comings of prior research by increasing the incentives for participants, expanding the generalizability of findings and examining research compliance and participant self-perception through debriefing. Discriminant analysis was utilized to determine if specific functions existed that would correctly classify and distinguish each experimental group. Several discriminant functions had at least moderate canonical correlations and good classification accuracy. Results also include utility estimates given projected varying base rates of malingering.

An exercise in story repair: A guided written disclosure protocol for fostering narrative completeness of traumatic memories. (open access)

An exercise in story repair: A guided written disclosure protocol for fostering narrative completeness of traumatic memories.

The present study sought to build on the large body of past research into written disclosure of traumatic memories. This research has consistently found that participants who write about their traumatic experiences realize long-term physiological and psychological health benefits. More recently, it has been found that those participants who realize the most benefits are those who progressively include more elements of a good narrative, or story, in their writing about a traumatic experience over several sessions. Therefore, research has begun to examine the role of language and the structure of language in the health benefits gained from written disclosure of traumatic memories. A guided written disclosure protocol was designed for the present study, which sought to aid participants in supplying an increasing amount of narrative structure to their written disclosures of a single traumatic experience. Participants (N = 30) completed several measures of psychological and physiological health prior to and one month after completing the guided written disclosure protocol. Analyses revealed that participants who completed all four writing sessions showed statistically significant reductions in symptoms of general psychological distress, obsessive-compulsive symptoms, and intrusive and avoidant symptoms related to the traumatic experience. No significant self-reported physiological health benefits were found. The …
