1126 to 1150 of 1,483The formation of abnormal associations in schizophrenia: neural and behavioral evidence.
It is hypothesized that due to an abnormal functioning of the reward system patients with schizophrenia form context-inappropriate associations. It has been shown that the dopamine target regions, especially the ventral striatum, are critical in the formation of reward associations. We wanted to examine how the ventral striatum responds as patients learn reward-related associations and how this neural response is linked to objective and subjective behavioral measures. Functional magnetic resonance imaging (fMRI) Blood oxygen level dependent (BOLD) responses were examined using aversive Pavlovian learning in 13 medicated patients with schizophrenia and 13 matched healthy controls. Colored circles served as conditioned stimulus (CS+) while a loud, individually adjusted, noise served as the unconditioned stimulus. Circles of another color served as neutral comparators (CS-). Subjective indi…

Predicting the completion of an integrative and intensive outpatient chronic pain treatment with the personality assessment inventory.
The effects of intensive, integrative treatments for chronic pain are affected by patient compliance, and in many cases, selecting noncompliant individuals adversely impacts the cost-effectiveness of such programs. The pretreatment identification of individuals who are at risk for dropout could assist clinicians in augmenting treatments with motivational enhancement strategies for high-risk patients or using such information to select individuals who are most likely to complete a given intervention program. In this study, we tested the ability of indicators from the Personality Assessment Inventory (PAI; Morey, 1991), administered prior to treatment, to identify individuals who dropped out of a 20-day chronic pain program. Results replicate findings from outpatient psychotherapy research in finding that PAI Mean Clinical Elevation and Treatment Process Index significantly differentiated …

A preliminary look at loneliness as a moderator of the link between perfectionism and depressive and anxious symptoms in college students: does being lonely make perfectionistic strivings more distressing?
An integrative model involving perfectionism [Hewitt, P. L., & Flett, G. L. (1991). Perfectionism in the self and social contexts: Conceptualization, assessment, and association with psychopathology. Journal of Personality and Social Psychology, 60, 456-470] and loneliness as predictors of depressive and anxious symptoms was proposed and tested in 383 college students. Beyond the expected additive influences of the two predictors in the prediction of symptoms, loneliness was also hypothesized to moderate the link between perfectionism and symptoms. Results indicated that other-oriented perfectionism predicted anxious symptoms, whereas socially prescribed perfectionism predicted both depressive and anxious symptoms. Loneliness was found to add incremental validity to these predictions. Moreover, the Perfectionism x Loneliness interaction was found to further augment the prediction of depr…

The roles of perceived teacher support, motivational climate, and psychological need satisfaction in students' physical education motivation.
Research illustrates the positive roles of perceived competence, autonomy, and mastery climate and the negative role of performance climate in student motivation in physical education. Less research has examined perceptions of relationships within this setting (i.e., perceived teacher support and relatedness) and their role in student motivation. The purpose of this study was to test the mediating roles of perceived competence, autonomy, and relatedness in the relationship between social contextual factors and motivation in physical education students (N = 508). Results from structural equation modeling showed that perceived competence, autonomy, and relatedness partially mediated the relationship between perceived teacher support and self-determined motivation and that mastery climate related directly to self-determined motivation. The results highlight the importance of perceived teach…

Origin myths in Bioethics: constructing sources, motives and reason in Bioethic(s).
Bioethics, the term now usually standing in for Biomedical Ethics, is a field of medical anthropological engagement. While many anthropologists and other social scientists work with bioethicists and physicians, this paper instead takes Bioethics as a topic of cultural research from the perspective of Cultural Bioethics and Interpretive Medical Anthropology. Application of useful findings of vintage anthropological research in cultural anthropology and the anthropology of religion and an interpretive lens reveal a field without a single origin or unified methodology. The paper suggests the appropriateness of a literal meaning of current conceptual commonality of the term Bioethics: that the term does in fact refer to a plurality of distinct enterprises with distinct origins and, hence, justifications.

Desire for motherhood: exploring HIV-positive women's desires, intentions and decision-making in attaining motherhood.
With access to prevention of parent-to-child transmission (PPTCT) and antiretroviral therapy (ARV), people living with HIV/AIDS are better able to consider childbearing and parenthood. However, there is limited understanding of the reproductive healthcare needs and the impact of infection on the fertility desires of women living with HIV/AIDS. Research on the relationship between fertility and HIV/AIDS has been largely clinical, focusing on the ability of women living with HIV/AIDS (WLHA) to conceive or their pregnancy outcomes. This paper describes the findings of a qualitative study undertaken in Namakkal district, Tamil Nadu, India that aimed to explore fertility desires, intentions and fertility decision-making in WLHA and the barriers they face in fulfilling these desires. In-depth interviews were held with selected 43 currently married WLHA aged 18-35 years and 10 key informants. T…

Ferguson E, Farrell K, Lawrence C (2008)MEDLINE-indexed journal, not yet read by usHealth psychology : official journal of the Division of Health Psychology, American Psychological Association102 citations Blood donation is an act of benevolence rather than altruism.
Objectives: Blood donation is described as an archetypal altruistic behavior, and recruitment/retention campaigns emphasize altruism. Here, a benevolence hypothesis for blood donation (both the donor and recipient benefit) rather than the altruism hypothesis (only the recipient gains) is proposed.
Design: Three United Kingdom-based studies contrasted benevolence and altruism: (a) a 6-month prospective study of blood donor behavior (Study 1: N = 957), (b) a cross-sectional study of blood donors' intentions (Study 2: N = 333), and (c) an experimental study examining the effect of benevolent and altruistic messages on willingness to help across high- and low-cost helping behaviors for committed and noncommitted blood donors (Study 3: N = 200).
Main outcome: Donor behavior and intentions-willingness.
Measures: Beliefs in personal and societal benefit (Time 1) and actual donations (Time 2) we…

Maximizing clinical research participation in vulnerable older persons: identification of barriers and motivators.
Objectives: To identify barriers and motivators to participation in long-term clinical research by high-risk elderly people and to develop procedures to maximize recruitment and retention.
Design: Quantitative and qualitative survey.
Setting: Academic primary care medicine and pre-anesthesia testing clinics.
Participants: Fifty patients aged 70 and older, including 25 medical patients at high risk of hospitalization and 25 patients with planned major surgery.
Measurements: Fifteen- to 20-minute interviews involved open- and closed-ended questions guided by an in-depth script. Two planned study protocols were presented to each participant. Both involved serial neuropsychological assessments, blood testing, and magnetic resonance brain imaging (MRI); one added lumbar puncture (LP). Participants were asked whether they would be willing to participate in these protocols, rated barriers and i…

Egalitarianism in young children.
Human social interaction is strongly shaped by other-regarding preferences, that is, a concern for the welfare of others. These preferences are important for a unique aspect of human sociality-large scale cooperation with genetic strangers-but little is known about their developmental roots. Here we show that young children's other-regarding preferences assume a particular form, inequality aversion that develops strongly between the ages of 3 and 8. At age 3-4, the overwhelming majority of children behave selfishly, whereas most children at age 7-8 prefer resource allocations that remove advantageous or disadvantageous inequality. Moreover, inequality aversion is strongly shaped by parochialism, a preference for favouring the members of one's own social group. These results indicate that human egalitarianism and parochialism have deep developmental roots, and the simultaneous emergence o…

Influence of chronic mild stress on the behavioural effects of acute tryptophan depletion induced by a gelatin-based mixture.
Several types of stress can increase vulnerability to developing depression. This depression may be caused by the effects of stress on the serotonergic system, which may make the system more vulnerable. The aim of this experiment was to evaluate whether chronic mild stress (CMS) resulted in long-lasting vulnerability of the serotonergic system, reflected by stronger behavioural responses to a serotonergic challenge with acute tryptophan depletion (ATD) several weeks after the CMS had ended. Male Wistar rats were exposed to 3 weeks of CMS followed by a 2-week resting period. CMS resulted in blunted weight gain and lower sucrose consumption. After the resting period, rats were repeatedly treated with a gelatin-based protein-carbohydrate mixture, either with or without L-tryptophan, to acutely challenge the serotonergic system and the rats were tested in several tests of anxiety-related and…

Delay of gratification and executive performance in individuals with schizophrenia: putative role for eating behavior and body weight regulation.
Objective: Impairment in executive functions and disturbed weight regulation are common features in individuals with schizophrenia on antipsychotics. Still, the clinical management of weight gain, including educational programs, is insufficient. Therefore, we hypothesized that distinct executive impairment is associated with the inability to self-control food intake.
Method: In the present study we investigated the performance in a paradigm analyzing the executive subfunction "delay of gratification" in individuals with schizophrenia (n=29) compared with controls (n=23) and the interrelationship between delay of gratification, overall executive functioning, reported eating behavior and the BMI. We applied a board-game paradigm to operationalize delay of gratification: on designated fields individuals need to decide about a small amount of immediate reinforcement versus double the amount …

Individual differences in delay discounting: relation to intelligence, working memory, and anterior prefrontal cortex.
Lower delay discounting (better self-control) is linked to higher intelligence, but the basis of this relation is uncertain. To investigate the potential role of working memory (WM) processes, we assessed delay discounting, intelligence (g), WM (span tasks, 3-back task), and WM-related neural activity (using functional magnetic resonance imaging) in 103 healthy adults. Delay discounting was negatively correlated with g and WM. WM explained no variance in delay discounting beyond that explained by g, which suggests that processes through which WM relates to delay discounting are shared by g. WM-related neural activity in left anterior prefrontal cortex (Brodmann's area 10) covaried with g, r= .26, and delay discounting, r=-.40, and partially mediated the relation between g and delay discounting. Overall, the results suggest that delay discounting is associated with intelligence in part be…

Motivational interviewing as a pregroup intervention for partner-violent men.
This study investigated the effects of a pregroup motivational intervention for domestic abuse perpetrators. Men presenting for treatment at a community domestic violence agency (N = 108) were assigned to receive either a two-session intake using the techniques of motivational interviewing (MI) or a structured intake (SI) control. All participants were then referred to a cognitive behavioral treatment (CBT) program in groups homogeneous with respect to intake condition. The motivational intake led to more constructive in-session behavior during the early phase of group CBT, greater compliance with group CBT homework assignments, higher late session therapist ratings of the working alliance, and more help seeking outside of the domestic violence program. No significant effects of intake condition were found on session attendance, self-reports of readiness to change abusive behavior, or cl…

College students who have an eveningness preference report lower self-control and greater procrastination.
Previous research suggests a possible link between eveningness and general difficulties with self-regulation (e.g., evening types are more likely than other chronotypes to have irregular sleep schedules and social rhythms and use substances). Our study investigated the relationship between eveningness and self-regulation by using two standardized measures of self-regulation: the Self-Control Scale and the Procrastination Scale. We predicted that an eveningness preference would be associated with poorer self-control and greater procrastination than would an intermediate or morningness preference. Participants were 308 psychology students (mean age=19.92 yrs) at a small Canadian college. Students completed the self-regulation questionnaires and Morningness/Eveningness Questionnaire (MEQ) online. The mean MEQ score was 46.69 (SD=8.20), which is intermediate between morningness and eveningne…

Academic buoyancy: Towards an understanding of students' everyday academic resilience.
Academic buoyancy is developed as a construct reflecting everyday academic resilience within a positive psychology context and is defined as students' ability to successfully deal with academic setbacks and challenges that are typical of the ordinary course of school life (e.g., poor grades, competing deadlines, exam pressure, difficult schoolwork). Data were collected from 598 students in Years 8 and 10 at five Australian high schools. Half-way through the school year and then again at the end of the year, students were asked to rate their academic buoyancy as well as a set of hypothesized predictors (self-efficacy, control, academic engagement, anxiety, teacher-student relationship) in the area of mathematics. Multilevel modeling found that the bulk of variance in academic buoyancy was explained at the student level. Confirmatory factor analysis and structural equation modeling showed …

Stoeber J, Becker C (2008)MEDLINE-indexed journal, not yet read by usInternational journal of psychology : Journal international de psychologie19 citations Perfectionism, achievement motives, and attribution of success and failure in female soccer players.
While some researchers have identified adaptive perfectionism as a key characteristic to achieving elite performance in sport, others see perfectionism as a maladaptive characteristic that undermines, rather than helps, athletic performance. Arguing that perfectionism in sport contains both adaptive and maladaptive facets, the present article presents a study of N = 74 female soccer players investigating how two facets of perfectionism-perfectionistic strivings and negative reactions to imperfection (Stoeber, Otto, Pescheck, Becker, & Stoll, 2007 )-are related to achievement motives and attributions of success and failure. Results show that striving for perfection was related to hope of success and self-serving attributions (internal attribution of success). Moreover, once overlap between the two facets of perfectionism was controlled for, striving for perfection was inversely related to…

A functional magnetic resonance imaging investigation of uncertainty in adolescents with anxiety disorders.
Background: Pediatric anxiety disorders, although highly prevalent, are understudied with little known about their pathophysiology. Intolerance of uncertainty (IU) is a trait associated with worry, a key characteristic of these disorders. Neural responses to uncertainty in healthy subjects involve the same frontal-limbic circuits that are hyper-responsive in pediatric anxiety. As such, the present study examines the relationship between IU and neural responses to uncertainty in anxious adolescents.
Methods: Sixteen adolescents (ages 13-17) diagnosed with generalized anxiety disorder and/or social phobia (ANX) and 13 non-anxious control subjects completed a decision-making task while functional magnetic resonance imaging scans were acquired.
Results: The ANX group endorsed greater task-related anxiety and less certainty than control subjects on a post-task questionnaire. Compared with con…

Background: Blood donation can be described as a prosocial behavior, and donors often cite prosocial reasons such as altruism, empathy, or social responsibility for their willingness to donate. Previous studies have not quantitatively evaluated these characteristics in donors or examined how they relate to donation frequency.
Study design and methods: As part of a donor motivation study, 12,064 current and lapsed donors answered questions used to create an altruistic behavior, empathetic concern, and social responsibility motivation score for each donor. Analysis of variance was used to compare mean scores by demographics and donor status and to determine the influence of each variable on the mean number of donations in the past 5 years.
Results: The mean score for each prosocial characteristic appeared high, with lower scores in male and younger donors. Higher altruistic behavior and so…

Depression and school performance in middle adolescent boys and girls.
The study aimed to investigate the associations between different levels of depression with different aspects of school performance. The target population included 2516 7th-9th grade pupils (13-17 years) of whom 90% completed the questionnaire anonymously in the classroom. Of the girls 18.4% and of the boys 11.1% were classified as being depressed (R-Beck Depression Inventory (BDI), the Finnish version of the 13-item BDI). The lower the self-reported grade point average (GPA) or the more the GPA had declined from the previous term, the more commonly the adolescents were depressed. Depression was associated with difficulties in concentration, social relationships, self-reliant school performance and reading and writing as well as perceiving schoolwork as highly loading. The school performance variables had similar associations with depression among both sexes when a wide range of depressi…

Motivational interviewing and cognitive behaviour therapy in the treatment of adolescent overweight and obesity: study design and methodology.
Background: Despite the high prevalence and negative physical and psychosocial consequences of overweight and obesity in adolescents, very little research has evaluated treatment in this population. Consequently, clinicians working with overweight and obese adolescents have little empirical research on which to base their practise. Cognitive behavioural therapy has demonstrated efficacy in promoting behaviour change in many treatment resistant disorders. Motivational interviewing has been used to increase motivation for change and improve treatment outcomes. In this paper we describe the rationale and design of a randomised controlled trial testing the efficacy of motivational interviewing and cognitive behaviour therapy in the treatment of overweight and obese adolescents.
Methods: Participants took part in a motivational interview or a standard semi-structured assessment interview and …

Multiple aspects of the stress response under social evaluative threat: an electrophysiological investigation.
Affective traits and states may be important moderators of stress reactivity, providing insight into stress-related consequences on cognitive functioning. This study assessed cognitive control processes using response-related brain electrical activities-the error-related negativity (ERN) and error positivity (Pe)-that are sensitive to trait and state affect. To assess the role of cognitive control in affective and cortisol reactivity to social evaluative threat, 55 undergraduates first completed a standard task designed to elicit the ERN in order to index 'baseline' error monitoring. Participants then performed a difficult mathematical task designed to elicit the ERN under conditions of exposed failure and social evaluation. Baseline ERN amplitude predicted future cortisol reactivity to social evaluative threat in highly punishment-sensitive individuals (high self-reported Behavioral Inh…

A 3-factor model for the FACIT-Sp.
Objective: The 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp) is a popular measure of the religious/spiritual (R/S) components of quality of life (QoL) in patients with cancer. The original factor analyses of the FACIT-Sp supported two factors: Meaning/Peace and Faith. Because Meaning suggests a cognitive aspect of R/S and Peace an affective component, we hypothesized a 3-factor solution: Meaning, Peace, and Faith.
Methods: Participants were 240 long-term female survivors of cancer who completed the FACIT-Sp, the SF-12, and the BSI 18. We used confirmatory factor analysis to compare the 2- and 3-factor models of the FACIT-Sp and subsequently assessed associations between the resulting solutions and QoL domains.
Results: Survivors averaged 44 years of age and 10 years post-diagnosis. A 3-factor solution of the FACIT-Sp significantly improved…

Promoting research participation: why not advertise altruism?
Participation rates have a major impact on the quality, cost and timeliness of health research. There is growing evidence that participation rates may be falling and that new research governance structures and procedures may be increasing the likelihood of recruitment bias. It may be possible to encourage public reflection about research participation and enhance recruitment by providing information about the potential benefits of research to others as well as to research participants and by stimulating debate and influencing social expectations about involvement. Publicly funded and charitable bodies use various forms of advertising to encourage altruistic behaviour and generate social expectations about donating money, blood and organs for the benefit of others. Consideration should be given to the use of similar persuasive communications to promote wider participation in health resear…
