Social Support and the Association of Type 2 Diabetes and Depressive and Anxiety Disorders Among Low-income Adults Seen in Primary Care Clinics

This study examined the association of social support (SS) and affective disturbance among low-income primary care patients with no chronic illnesses vs. those with type 2 diabetes vs. those with other chronic illnesses. The sample was predominantly middle aged (47.2 years old), African American (74%) and female (80%), with an average individual monthly income of approximately $500. Participants (N = 326) were administered the Diagnostic Interview Schedule, IV and the Interpersonal Support Evaluation List. Logistic regression results indicated that each standard deviation decrease in SS, increased the odds of having a depressive or anxiety disorder diagnosis by .618 OR (CI .472, .808, p < .000) for all study participants; .438 OR (95% CI .195, .987, p = .046) for those with hypertension, asthma and/or arthritis; and .326 OR (95% CI .141, .755, p = .009) for those with type 2 diabetes. Results suggest that SS may serve an important role in the association between stress and depression/anxiety diagnoses among low-income, primary care patients. This paper was awarded the Lifescan Diabetes Research Award at the 23rd Annual Meeting of the Society of Behavioral Medicine.     

Relations and effects of transformational leadership: a comparative analysis with traditional leadership styles

This study has two main goals: (a) to compare the relationship between transformational leadership and other important leadership styles (i.e., democratic versus autocratic or relations- and task-oriented leadership) and (b) to compare the effects of transformational leadership and the other styles on some important organizational outcomes such as employees' satisfaction and performance. For this purpose, a sample of 147 participants, working in 35 various work-teams, was used. Results show high correlations between transformational leadership, relations-oriented, democratic, and task-oriented leadership. On the other hand, according to the literature, transformational leadership, especially high levels, significantly increases the percentage of variance accounted for by other leadership styles in relevant organizational outcome variables (subordinates' performance, satisfaction and extra effort).     

A loss of status and a sense of defeat: an evolutionary perspective on professional burnout

This longitudinal study among Spanish teachers (N = 558) examined burnout from an evolutionary social rank perspective. The types of stress differed among various school levels, and a sense of defeat was highest among teachers in primary schools. A low status, a loss of status and a sense of defeat were independent cross‐sectional predictors of burnout. Longitudinally a sense of defeat predicted an increase in burnout over time, especially among males and teachers in high schools. The status related variables were in general more important predictors of burnout than stressors that are usually associated with burnout. Copyright © 2007 John Wiley & Sons, Ltd.     

Teachers’ implicit view of intelligence predict pupils’ self-perception as learners

Teachers regularly make judgements about their pupils’ intelligence while interacting with them in the classroom. The main aims of this paper are to analyse the structure of teachers’ judgements of their pupils’ intelligence, and to evaluate the influence that teachers have on pupils’ judgements of their own and their peers’ intelligence. Cross-cultural comparisons between English and Portuguese pupils are considered. In total 58 children 10- to 11-year-old and two teachers from London, UK and 47 children 5- to 6-year-old and two teachers from Lisbon, Portugal participated. The children completed aptitude tests and self-perception measures for general ability, reading and mathematical ability. The teachers ranked their pupils’ academic abilities from ‘best in the class’ to ‘weakest in the class’. Results show that teachers’ implicit conceptions of intelligence reflect a view of intelligence that is similar to what IQ tests measure. In addition the results support the notion that children’s verbal ability is more highly valued than mathematical ability. Moreover, the results also suggest that teachers have a considerable impact on their pupils’ self-perception as learners. Cultural differences are also discussed.     

Associative independence revisited: competition between conflicting associations can be resolved or even reversed in one trial

In one type of association-memory paradigm, after studying pairs of the form AB, AC, participants must recall both B and C in response to A. Counterintuitively, yet often replicated, recall probabilities of B and C are typically uncorrelated (“associative independence”). This face-value independence is now understood to reflect a negative correlation due to AB and AC competing, approximately offset by a positive correlation produced by subject- and item-variability. The outcome might vary with stimulus material; for noun-pairs, and with a single study trial per pair, AB and AC have been found to be positively correlated. We replicated the positive correlation between AB and AC for noun-pairs, but this did not differ from the correlation expected for independent memory tests, suggesting that for noun pairs, AB and AC are independent on average. In Experiment 2, participants instructed to form separate images for AB and AC again produced an independence pattern, but participants instructed to combine AB and AC into an integrative image produced a facilitation pattern. Thus, the relationship between AB and AC varies, and can be influenced by study strategy. Association-memory models may need to accommodate a diverse range of AB–AC relationships, and studies that build on AB/AC learning may need to consider whether AB/AC start out with a competitive, facilitatory or independent relationship.     

The free and cued selective reminding test for predicting progression to Alzheimer's disease in patients with mild cognitive impairment: A prospective longitudinal study

Amnestic mild cognitive impairment (aMCI) patients carry a greater risk of conversion to Alzheimer's disease (AD). Therefore, the International Working Group (IWG) on AD aims to consider some cases of aMCI as symptomatic prodromal AD. The core diagnostic marker of AD is a significant and progressive memory deficit, and the Free and Cued Selective Reminding Test (FCSRT) was recommended by the IWG to test memory in cases of possible prodromal AD. This study aims to investigate whether the performance on the FCSRT would enhance the ability to predict conversion to AD in an aMCI group. A longitudinal study was conducted on 88 aMCI patients, and neuropsychological tests were analysed on the relative risk of conversion to AD. During follow‐up (23.82 months), 33% of the aMCI population converted to AD. An impaired FCSRT TR was significantly associated with the risk of conversion to dementia, with a mean time to conversion of 25 months. The FCSRT demonstrates utility for detecting AD at its prodromal stage, thus supporting its use as a valid clinical marker.     

Self-Criticism Impacts Emotional Responses to Pain

Nonsuicidal self-injury (NSSI) is associated with numerous negative outcomes (e.g., suicide attempts), making it a focus of great clinical concern. Yet, mechanisms reinforcing NSSI remain unclear. The benefits and barriers model proposes that NSSI engagement is determined by both benefits of and barriers to NSSI. Benefits include mood improvement, a function reported by most who engage in NSSI; barriers include a desire to avoid pain and bodily harm. Self-criticism is generally understood as a trait lowering desire to avoid pain and bodily harm, thus decreasing that specific barrier. However, recent research demonstrated that self-criticism may also increase NSSI benefits. Highly self-critical people may view NSSI and pain in the context of feeling deserving of pain and punishment—thus, pain may improve mood for self-critical individuals. We tested whether self-criticism impacted emotional responding to pain among adult females with (n = 44) and without (n = 65) NSSI histories. After a negative mood induction, participants rated their moods before, during, and after self-administered pain. In participants with and without NSSI histories, self-criticism was positively correlated with mood improvements during pain. Thus, regardless of NSSI history, self-criticism impacted emotional responses to pain. Together, results suggest that self-criticism may not only decrease an important NSSI barrier but also enhance NSSI benefits, specifically leading to more mood improvement during pain.     

The world may not be just for you but you'd better not say it: On the social value of expressing personal belief in a just world

The expression of personal belief in a just world (PBJW) has been discussed as a criterion of excellence in social judgments. In four experimental studies we hypothesized and found that targets who express high versus low PBJW are judged as more: (i) deserving of success and (ii) suited to socio-organizational expectations. The four studies show that suitability to socio-organizational expectations mediates the relation between PBJW expressed and success deservingness, even after controlling for judgments of likability, status, rationality, optimism, and targets as victims. Studies 2 and 3 show this pattern occurs regardless of target performance appraisal. Study 4 indicates that expressing low PBJW decreases the social value of individuals, but expressing high PBJW does not increase it. We discuss the impact of PBJW expression on people's lives, namely on upward social mobility of members of low-status groups, and the influence of the negativity bias on judgments caused by PBJW expression.     

Speech rhythm alterations in Spanish-speaking individuals with Alzheimer’s disease

Rhythm is the speech property related to the temporal organization of sounds. Considerable evidence is now available for suggesting that dementia of Alzheimer’s type is associated with impairments in speech rhythm. The aim of this study is to assess the use of an automatic computerized system for measuring speech rhythm characteristics in an oral reading task performed by 45 patients with Alzheimer’s disease (AD) compared with those same characteristics among 82 healthy older adults without a diagnosis of dementia, and matched by age, sex and cultural background. Ranges of rhythmic-metric and clinical measurements were applied. The results show rhythmic differences between the groups, with higher variability of syllabic intervals in AD patients. Signal processing algorithms applied to oral reading recordings prove to be capable of differentiating between AD patients and older adults without dementia with an accuracy of 87% (specificity 81.7%, sensitivity 82.2%), based on the standard deviation of the duration of syllabic intervals. Experimental results show that the syllabic variability measurements extracted from the speech signal can be used to distinguish between older adults without a diagnosis of dementia and those with AD, and may be useful as a tool for the objective study and quantification of speech deficits in AD.
