Can the onset of type 2 diabetes be delayed by a group-based lifestyle intervention? A randomised control trial

This study was a randomised control trial with a waiting control group. It was designed to evaluate the effectiveness of a 6-month, group-based diabetes prevention programme, The Healthy Living Course and assess whether participation in the programme led to changes in modifiable risk factors for type 2 diabetes among an already at-risk pre-diabetic population. Individuals designated at risk for diabetes by their general practitioners (GPs) were screened using an Oral Glucose Tolerance Test. Volunteers (N?=?307) with pre-diabetes were assigned to an intervention or wait-control group in the ratio of approximately 2?:?1. The sample was pre-tested on biochemical, anthropometric and self-report behavioural, cognitive and mood variables and post-tested either at the end of the educational/support-based lifestyle programme or the end of the wait period. The intervention group significantly improved their diabetes knowledge, motivation to change, positive affect, healthy eating and activity levels and showed significantly greater reductions in weight, body mass index, waist circumference, diastolic blood pressure and fasting plasma glucose in comparison with controls. The intervention group also changed their diagnostic status from pre-diabetes to non-diabetes at a greater rate than the wait group (43% vs. 26%) who received standard care from their GPs.     

Thou shalt not discriminate: How emphasizing moral ideals rather than obligations increases Whites' support for social equality

An important step toward reducing group-based disparities in society is creating support for equality among advantaged group members (e.g., Whites and men). The current research examined how presenting social equality between ethnic groups in terms of moral ideals (i.e., equal treatment) vs. moral obligations (i.e., non-discrimination) affected the attitudes of Whites (students in Study 1, N = 45 and 2, N = 44 and employees in Study 3a, N = 67 and Study 3b, N = 62) toward various social equality issues. It was found that participants in the moral ideals condition reported more activation rather than inhibition tendencies regarding equality (Study 1), were more supportive of affirmative action (Study 2), indicated lower levels of social identity threat, and were more favorable toward cultural diversity which resulted in greater prioritization of equality (Study 3a) than those in the moral obligation condition. These effects did not arise when the ideals/obligations distinction was applied to a nonmoral domain (i.e., competence, Study 3b), underlining the central argument that these processes are specific to morality. The broader theoretical implications for morality and intergroup research are discussed.     

Individual differences at high perceptual load: the relation between trait anxiety and selective attention

Attentional control theory (Eysenck et al., 2007) posits that taxing attentional resources impairs performance efficiency in anxious individuals. This theory, however, does not explicitly address if or how the relation between anxiety and attentional control depends upon the perceptual demands of the task at hand. Consequently, the present study examined the relation between trait anxiety and task performance using a perceptual load task (Maylor & Lavie, 1998). Sixty-eight male college students completed a visual search task that indexed processing of irrelevant distractors systematically across four levels of perceptual load. Results indicated that anxiety was related to difficulty suppressing the behavioural effects of irrelevant distractors (i.e., decreased reaction time efficiency) under high, but not low, perceptual loads. In contrast, anxiety was not associated with error rates on the task. These findings are consistent with the prediction that anxiety is associated with impairments in performance efficiency under conditions that tax attentional resources.     

Is the world a just place? Countering the negative consequences of pervasive discrimination by affirming the world as just

Two studies (a) explored the role of pervasiveness of discrimination (pervasive vs. rare) in determining targets' responses to discrimination, and (b) examined the extent to which threats to participants' worldview can account, in part, for detrimental effects of pervasive discrimination. As predicted, across both studies, pervasiveness of discrimination moderated the relationship between attributions to prejudice for failure to obtain a job and psychological well-being (depressed affect and state self-esteem). When discrimination was presented as pervasive, attributions to prejudice related to lower state self-esteem and greater depressed affect. When discrimination was portrayed as rare, attributions to prejudice were related to higher state self-esteem and unrelated to depressed affect. Study 2 further showed that being able to affirm the world as just countered the negative consequences of pervasive discrimination, whereas it did not influence responses to discrimination that was perceived as rare.     

Sharing moral values: anticipated ingroup respect as a determinant of adherence to morality-based (but not competence-based) group norms

This research examines how moral values regulate the behavior of individual group members. It argues that group members behave in line with moral group norms because they anticipate receiving ingroup respect when enacting moral values that are shared by ingroup members. Data from two experimental studies offer evidence in support. In Study 1 (N = 82), morality-based (but not competence-based) ingroup norms determined whether members of a low-status group opted for individual versus collective strategies for status improvement. This effect was mediated by anticipated ingroup respect and emerged regardless of whether group norms prescribed collectivistic or individualistic behavior. These effects were replicated in Study 2 (N = 69), where no comparable effect was found as a result of moral norms communicated by a higher status outgroup. This indicates that social identity implications rather than interdependence or more generic concerns about social approval or importance of cooperation drive these effects.     

Developmental trajectories in toddlers' self-restraint predict individual differences in executive functions 14 years later: a behavioral genetic analysis

We examined whether self-restraint in early childhood predicted individual differences in 3 executive functions (EFs; inhibiting prepotent responses, updating working memory, and shifting task sets) in late adolescence in a sample of approximately 950 twins. At ages 14, 20, 24, and 36 months, the children were shown an attractive toy and told not to touch it for 30 s. Latency to touch the toy increased with age, and latent class growth modeling distinguished 2 groups of children that differed in their latencies to touch the toy at all 4 time points. Using confirmatory factor analysis, we decomposed the 3 EFs (measured with latent variables at age 17 years) into a Common EF factor (isomorphic to response inhibition ability) and 2 factors specific to updating and shifting. Less-restrained children had significantly lower scores on the Common EF factor, equivalent scores on the Updating-Specific factor, and higher scores on the Shifting-Specific factor than did the more-restrained children. The less-restrained group also had lower IQ scores, but this effect was entirely mediated by the EF components. Twin models indicated that the associations were primarily genetic in origin for the Common EF variable but split between genetics and nonshared environment for the Shifting-Specific variable. These results suggest a biological relation between individual differences in self-restraint and EFs, one that begins early in life and persists into late adolescence.     

Development of neural systems for processing social exclusion from childhood to adolescence

Adolescence is a period of development in which peer relationships become especially important. A computer-based game (Cyberball) has been used to explore the effects of social exclusion in adolescents and adults. The current functional magnetic resonance imaging (fMRI) study used Cyberball to extend prior work to the cross-sectional study of younger children and adolescents (7 to 17 years), identifying age-related changes in the neural correlates of social exclusion across the important transition from middle childhood into adolescence. Additionally, a control task illustrated the specificity of these age-related changes for social exclusion as distinct from expectancy violation more generally. During exclusion, activation in and functional connectivity between ventrolateral prefrontal cortex and ventral anterior cingulate cortex increased with age. These effects were specific to social exclusion and did not exist for expectancy violation. Our results illustrate developmental changes from middle childhood through adolescence in both affective and regulatory brain regions during social exclusion.     

Incorporating Religion/Spirituality Into Treatment for Serious Mental Illness

This paper examines whether religion and spirituality (R/S) should be incorporated into treatment for patients with serious mental illness. This question merits attention, especially in light of the strong presence of R/S in the United States and, in particular, among members of ethnic minorities. While the literature is somewhat mixed, prior research supports the view that incorporating adaptive R/S elements into treatment for patients with serious mental illness is beneficial, particularly for patients who do not exhibit severe psychotic symptoms. Drawing from our experiences in developing a family-focused Culturally-Informed Therapy for Schizophrenia (CIT-S), we will also highlight the importance of addressing spiritual issues within minority populations. In the second half of this paper, we will present several case illustrations of how R/S issues were used in CIT-S to help patients make sense of adverse situations and obtain much-needed support and coping resources outside the treatment room. Findings from this study indicate that religion and spirituality can often be incorporated into treatment in a way that coalesces with patients’ values and enhances treatment gains. Future research should investigate how therapists’ own R/S values interact with those of their clients, and whether congruency in R/S values has any impact on treatment efficacy.     

Anxiety as a Predictor of Age at First Use of Substances and Progression to Substance Use Problems Among Boys

This study examined associations of generalized and social anxiety with (1) age at first use of tobacco, alcohol, and marijuana and (2) interval from first use to first problem use of each substance. Participants were 503 males who comprised the youngest cohort (first assessed in the first grade) of the Pittsburgh Youth Study, a longitudinal community-based study of boys. Annual assessments of generalized and social anxiety, delinquency, and substance use from first grade through high school were included. Both types of anxiety predicted earlier first use of alcohol and tobacco, and generalized anxiety predicted earlier first use of marijuana. Both types of anxiety predicted the progression from first use to problems related to marijuana. The effect of generalized anxiety tended to be significant above and beyond the effect of delinquency, while the effect of social anxiety on risk for first use of substances was not. Overall, the associations between anxiety and substance use and related problems depend on the class of substance and the type of anxiety.
