The Utility of the Spatial Span from the Wechsler Memory Scales in a Geriatric Population with Cognitive Impairments (open access)

The Utility of the Spatial Span from the Wechsler Memory Scales in a Geriatric Population with Cognitive Impairments

Performance on the Spatial Span subtest of the Wechsler Memory Scale has been viewed as an indicator of working memory and visuospatial processing. A number of factors including age and gender have been posited to effect performance on Spatial Span by older adults. The current study examined the impact of various forms of cognitive impairment and severity of impairment on Spatial Span performance. Five hundred thirty-eight individuals between the ages of 65 and 89 were evaluated in a university memory disorders clinic using a battery of neuropsychological tests that included Spatial Span. Participants were grouped by consensus diagnosis into type of cognitive impairment (Alzheimer's disease, vascular disease, amnestic mild cognitive impairment or non-amnestic mild cognitive impairment) or cognitively normal. As expected, an increase in severity of impairment results in a decrease in Spatial Span Total Score. Other findings included a weak relationship between age and Spatial Span Total Score. Gender, as well as age, did not fully account for the decline in Spatial Span Total Score. Spatial Span Forward score was not as good a predictor of severity in that reduction in score for Spatial Span Forward remains relatively stable regardless of level of impairment. Spatial Span Backward performance was …

Identifying the Level of Prognostic Information Desired by People with Cancer (open access)

Identifying the Level of Prognostic Information Desired by People with Cancer

The study explored whether certain factors might be used to distinguish between people with cancer who do or do not want detailed information about their disease progress, do or do not want to be informed if their disease is no longer considered curable, and who do or do not want an estimation of life expectancy if their disease is no longer considered curable. The factors included whether an individual has an internal versus external locus of control, uses an active coping strategy or a planning coping strategy, the level of spirituality, and age. Participants consisted of 51 people with cancer from a cancer center in the state of Washington. Results indicated that 98% wanted detailed information about their disease progress, 94% wanted to be informed if their disease was no longer considered curable, and 78% wanted an estimation of life expectancy if their disease was no longer considered curable. Due to the majority of the participants endorsing the need for prognostic information none of the factors (e.g. coping strategies, locus of control, spirituality) were able to predict the information needs of the patients with cancer. Clinical implications of this study suggest that physicians have an ongoing, open dialogue with their …

Cross-cultural Differences in the Presentation of Depressive Symptoms (open access)

Cross-cultural Differences in the Presentation of Depressive Symptoms

Epidemiological studies show that China has a lower prevalence rate of major depression than that of Western countries. The disparity in prevalence is commonly attributed to the tendency of Chinese to somatize depression. Empirical evidence of Chinese somatization has yielded mixed results. The present study thus aimed to 1) examine differences in somatic and psychological symptom reporting between Chinese from Macau and Americans in America and 2) identify cultural and psychological variables that would predict somatization. Independent and interdependent self-construals, sociotropy, and emotional approach coping were hypothesized to predict somatization of depression. Participants included 353 Chinese and 491 American college students who completed self-report measures online. Contrary to prediction, results indicated that Americans endorsed a higher proportion of somatic symptoms than Chinese did. Sociotropy predicted both relative endorsement and severity of somatic symptoms for the American sample, whereas emotional expression coping was related to somatization in the Chinese sample. The findings challenge the common assumption of greater Chinese somatization and highlight the importance of context in understanding the relationships between somatization and cultural and psychological variables. Implications of the present study and future directions are discussed.

Does Prostate Cancer Begin in the Prostate? Key Predictors of Diagnosis (open access)

Does Prostate Cancer Begin in the Prostate? Key Predictors of Diagnosis

The purpose of this exploratory study was to identify the key predictors of prostate cancer; such study may lead to the development of appropriate interventions and prevention. Previous epidemiological studies have found these following factors to be key predictors for being diagnosed with hormone-associated carcinoma such as prostate cancer: age, ethnicity, physical activity, family history, diet, sleep amount, marital status, and having another form of carcinoma. Many studies have included results only for men over the age of 65, however, prostate cancer is claiming the lives of many African American, Hispanic and White American men over the age of 35, and younger men are more likely to battle it if they are genetically predisposed. The sample population (N =21,646) was selected because men aged 35 or over have the highest prevalence of prostate cancer. Of this sample, 619 reported having prostate cancer, and 1,401 reported having some other type of cancer. This study employs a logistic regression model using SAS® and utilizes the National Health Interview Survey data set and a multivariate analysis of the years 2006, 2007, and 2008. To improve the quality of future research the methods need modification, the subpopulation being studied should be larger, and the …

The Effects of Priming, Culture, and Context on Perception of Facial Emotion, Self-representation and Thought: Brazil and the United States (open access)

The Effects of Priming, Culture, and Context on Perception of Facial Emotion, Self-representation and Thought: Brazil and the United States

Individualist and collectivist cultural approaches describe the relationship between an individual and his or her social surroundings. the current study had a two-fold purpose. the first was to investigate whether Brazilians, like other collective peoples, displayed more group self-representations, categorized items more relationally and paid more attention to context than Americans. the second purpose of this study was to investigate if counter-cultural primes played a role in activating either collective or individual selves. Both American (n = 100) and Brazilian (n = 101) participants were assigned either to a no-prime condition or a counter-cultural prime condition and then were asked to rate emotion cartoons, categorize items, complete the Twenty Statement Test (TST), and choose a representative object. As expected, unprimed Brazilian participants displayed more collectivist patterns on emotional (F[1,196] = 10.1, p = .001, ?²= .049; F[1,196] = 7.9, p = .006, ?²= .038; F[1,196] = 9.0, p = .005, ?²= .044) and cognitive (F[1, 196] = 6.0, p < .01, ?² = .03) tasks than Americans. However, Brazilians offered more individualist self-representations (F[1, 195] = 24.0, p < .001, ?² = .11) than American participants. Priming only had a marginal effect on item categorization (F[1,194] = 3.9, p = …

Back in My Hands: The Role of Self-Forgiveness and Stigma in HIV-Positive Adults (open access)

Back in My Hands: The Role of Self-Forgiveness and Stigma in HIV-Positive Adults

While advancements in treatment have made HIV a more manageable disease, only recently have psychosocial variables associated with the health of persons living with HIV (PLH) began to receive increased scrutiny. HIV-related stigma, considered by some researchers to be a “second epidemic,” is one such psychosocial variable and is associated with negative physiological and psychological health outcomes. In an effort to alleviate the effects of stress, increased research attention has focused on forgiveness as a teachable coping strategy. Current forgiveness interventions demonstrate encouraging results in decreasing anger and neutralizing stress but have not been applied to HIV-positive populations. In this study, Lazarus and Folkman’s transactional model of stress and coping (1984) and Prochaska and Velicer’s transtheoretical model of health behavior (1997) were utilized as theoretical frameworks to inform a randomized clinical trial that examines coping skills, particularly forgiveness, in PLH and perceived HIV-related stigma. An ethnically diverse sample of HIV-positive adults (n = 57) was randomized into a treatment or control group. The treatment group participated in six weeks of cognitive-behavioral group therapy that focused on the teaching of forgiveness as an effective coping tool while the control group was psychoeducational in nature and did not involve mention of forgiveness. …

An Exploration of the Criterion and Construct Validity of the Self-Compassion Scale (open access)

An Exploration of the Criterion and Construct Validity of the Self-Compassion Scale

Past research indicates that self-compassion has positive implications for psychological health and functioning. However, as a newly specified construct, the literature regarding self-compassion could benefit from a more thorough validation of the primary scale used in this area of research, the Self-Compassion Scale. In the present study, structural path analysis (using Amos) was used to explore the criterion validity of the SCS with four variables which have been theorized to be relevant to self-compassion (caregiver emotional responsiveness, fear of emotion, internalized spirituality, and achievement goal orientation). Initial hypothesis testing indicated support for the path model, with the exception of achievement goals which were not significantly associated with self-compassion. Trimming these paths in a subsequent analysis improved model fit. Interestingly, further analyses of the model indicated that the pairing of participant and parent gender produced substantial differences in path coefficients. Next, correlational and factor analytic methods were used to test the construct validity of the SCS. Correlational analyses found adequate convergent construct validity but some lack of divergent validity between SCS dimensions and conceptually similar constructs (i.e., fear of emotion, social connectedness and self-criticism). Confirmatory factor analysis indicated that a two-factor model fit the data better than the one-factor model proposed …
