Clinical and functional correlates of processing speed in pediatric Attention-Deficit/Hyperactivity Disorder: a systematic review and meta-analysis

It is well established that processing speed is negatively impacted in children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). Unfortunately, exactly how processing speed vulnerabilities manifest in daily functioning has not been well established. To support clinical care of youth with ADHD, it is important to better understand the functional consequences and relevant outcomes associated with processing speed deficits. This systematic review and meta-analysis sought to identify the association between processing speed and clinical or functional correlates among children or adolescents diagnosed with ADHD. A total of 409 abstracts were screened, of which, 60 full-text articles were identified as potentially relevant, and 8 of these studies met inclusion criteria. Domains evaluated across these studies included reading skills, mathematics skills, written expression, anxiety, self-appraisals of competence, and adaptive functioning. Six studies reported an association between processing speed and reading skills, allowing for meta-analysis. Processing speed difficulties among youth with ADHD appear strongly associated with several clinical and functional correlates including weaker academic skills, poorer adaptive skills, increased self-reported anxiety, and overestimates of social competence. Meta-analytic results for studies reporting the association between processing speed and reading skills indicate a medium overall weighted mean effect size (r = 0.33, 95% CI = 0.28 –0.39) with minimal heterogeneity (I² = 0.17). Clinical implications of these findings, limitations in the current knowledge base, and suggestions for future research are discussed.     

Aggression is associated with greater subsequent alcohol consumption: A shared neural basis in the ventral striatum

Alcohol use and abuse (e.g., binge drinking) are among the most reliable causes of aggressive behavior. Conversely, people with aggressive dispositions (e.g., intermittent explosive disorder) are at greater risk for subsequent substance abuse. Yet it remains unknown why aggression might promote subsequent alcohol use. Both aggressive acts and alcohol use are rewarding and linked to greater activity in neural reward circuitry. Through this shared instantiation of reward, aggression may then increase subsequent alcohol consumption. Supporting this mechanistic hypothesis, participants’ aggressive behavior directed at someone who had recently rejected them, was associated with more subsequent beer consumption on an ad‐lib drinking task. Using functional MRI, both aggressive behavior and beer consumption were associated with greater activity in the bilateral ventral striatum during acts of retaliatory aggression. These results imply that aggression is linked to subsequent alcohol abuse, and that a mechanism underlying this effect is likely to be the activation of the brain's reward circuitry during aggressive acts.

     

Human Chances for Happiness: A Review of Freud’s Civilization and Its Discontents

Sigmund Freud referred to his Civilization and Its Discontents (Freud 1930/1961) as an “inquiry concerning happiness.” In this article we discuss what he has to say about happiness. We focus on the reasons he gives for why lasting happiness is impossible to realize; his view that human beings tend to give precedence to the reduction of suffering over the desire for happiness; his suggestion that the best path to follow for what degrees of happiness are realizable depends on the individual; his view that pleasurable experiences are the basis for happiness and that no pleasures are comparable to that which occurs when one’s love is reciprocated by the other; the importance he places on the conflict between genital love and aim-inhibited forms of libidinal connection; his view that civilization plays a doubtful role as far as the realization of personal happiness is concerned; and his view of the role that human aggression and the sense of guilt play in promoting the unhappiness of civilized people. We conclude by offering seven comments on Freud’s views on the chance for human happiness.     

Bioethics and Pastoral Concern: Some Possible New Directions in Pastoral Theology

This special issue of the journal is comprised of papers given at a conference in May 2011 at the University of Texas Health Science Center at Houston on the theme of “Social Justice and the Health Professions.” This article offers the following rationale for this special issue in particular and for pastoral theologians to contribute to bioethics in general: (1) two contemporary theological thinkers in bioethics, Karen Lebacqz and Lisa Cahill, argue that theological discussions of justice broaden and deepen discussions of justice in mainstream bioethics—thus the focus on social justice provides an area for interdisciplinary and intersectional work; (2) pastoral theologians have not, to a great extent, contributed to discussions of religion and bioethics—this has been the territory of theological ethicists, especially during the 1970s; (3) one influential pastoral theologian, Bonnie Miller-McLemore, has called for (a) a broader concern for health in pastoral theology beyond psychological health and (b) more disciplinary approaches within pastoral theology beyond psychology so as to attend to “the living human web”; and (4) one way to advance the theological contributions in bioethics is by inviting pastoral theologians to focus on matters of social justice (an established area of intersection) as identified by health professionals, thus providing (a) new areas for inquiry and (b) new theological perspectives in bioethics. This article also suggests that pastoral theologians can contribute to bioethics by focusing on both “macro” issues (issues relating to structures and groups) and “micro” issues (issues relating to persons and experiences) as a way of pursuing the topic of justice in bioethics. The bulk of this article focuses on “macro” issues, but, in closing, the author articulates how he has been addressing “micro” issues in his own work. The author argues that both of these approaches—“macro” and “micro”—are legitimate ways for pastoral theologians to express pastoral concerns in bioethics.     

Later life health optimism,pessimism and realism: Psychosocial contributors and health correlates

Prior research has established positive outcomes of health optimism (appraising one's health as good despite poor objective health (OH)) and negative outcomes of health pessimism (appraising health as poor despite good OH), yet little is known about their contributors. We examined the role of psychosocial factors (life event stress, depression, dispositional optimism, perceived social support) in health realism (appraising health in accordance with OH), optimism and pessimism among 489 older men and women. We then accounted for the psychosocial factors when examining multiple health correlates of health realism, optimism and pessimism. Controlling for age, gender and income, regression results indicate that depression and social support were associated with less health optimism, while dispositional optimism was associated with greater health optimism among those in poor OH. Dispositional optimism was associated with less health pessimism and life event stress was associated with greater pessimism among those in good OH. Beyond the effects of the psychosocial factors, structural equation model results indicate that health optimism was positively associated with healthy behaviours and perceived control over one's health; health pessimism was associated with poorer perceived health care management. Health optimism and pessimism have different psychosocial contributors and health correlates, validating the health congruence approach to later life well-being, health and survival.     

Path analysis of exercise treatment-induced changes in psychological factors leading to weight loss

Physical activity may affect weight loss largely through psychological pathways associated with eating changes, especially in obese individuals whose caloric expenditure through exercise is typically small. Direct testing of this is, however, lacking. Previously sedentary adults (N?=?114; 77% female; M _age?=?43.3 years), with a minimum body mass index (BMI) of 35?kg/m² (M _BMI?=?42.0?kg/m²), participated in a 24-week treatment of cognitive-behavioural exercise support and nutrition information. A path model based on tenets of social cognitive and self-efficacy theory was constructed. It was expected that improvements in self-efficacy, physical self-concept, body satisfaction and mood associated with the exercise treatment would predict changes in self-regulation and increased physical activity. It was also hypothesised that improvements in self-efficacy and self-regulation for appropriate eating would transfer from these relationships and predict weight loss. After three theoretically viable paths were added based on modification indices, structural equation modelling indicated a good fit with the data, χ ²(16)?=?20.53, p?=?0.20; RMSEA?=?0.05; SRMR?=?0.06; CFI?=?0.97; TLI?=?0.95. Associations of psychological effects linked to exercise programme participation with predictors of appropriate eating and weight loss were found, and may inform theory, research and treatments.     

Recommendations for Increasing Replicability in Psychology

Replicability of findings is at the heart of any empirical science. The aim of this article is to move the current replicability debate in psychology towards concrete recommendations for improvement. We focus on research practices but also offer guidelines for reviewers, editors, journal management, teachers, granting institutions, and university promotion committees, highlighting some of the emerging and existing practical solutions that can facilitate implementation of these recommendations. The challenges for improving replicability in psychological science are systemic. Improvement can occur only if changes are made at many levels of practice, evaluation, and reward.

Does Dispositional Aggression Feed the Narcissistic Response? The Role of Narcissism and Aggression in the Prediction of Job Attitudes and Counterproductive Work Behaviors

Purpose

The purpose of this study was to extend the personality and work-related outcomes literature by examining: (1) the effects of narcissism on job satisfaction, organizational commitment, and counterproductive work behaviors and (2) the moderating effects of dispositional aggression on the narcissism–counterproductive work behaviors relationship.

Design/Methodology/Approach

Multi-wave data were collected from 381 workers employed in a variety of work settings within the United States.

Findings

Narcissism had consistent main effects on job satisfaction, organizational commitment, and counterproductive work behaviors after controlling for the personality characteristics agreeableness, conscientiousness, neuroticism, and aggression. Aggression moderated the relationship between narcissism and counterproductive work behaviors, such that the positive relationship between narcissism and counterproductive work behaviors was stronger when dispositional aggression was high.

Implications

This study provides greater clarity regarding the role of narcissism within job attitudes and behaviors, shows that dispositional aggression strengthens or amplifies the narcissistic response for counterproductive work behaviors, and provides a platform to further explore narcissism and aggression within the workplace.

Originality/Value

This study found that narcissism consistently predicted unique variance in work-related criteria after the effects of agreeableness, conscientiousness, neuroticism, and aggression were controlled. It also found evidence that aggression moderates the effects of narcissism on counterproductive work behaviors. This study is the first to directly examine these effects.
