The Shifting Subtypes of ADHD: Classification Depends on How Symptom Reports are Combined

Research on the correlates of ADHD subtypes has yielded inconsistent findings, perhaps because the procedures used to define subtypes vary across studies. We examined this possibility by investigating whether the ADHD subtype distribution in a community sample was sensitive to different methods for combining informant data. We conducted a study to screen all children in grades 1-5 (N = 7847) in a North Carolina County for ADHD. Teachers completed a DSM-IV behavior rating scale and parents completed a structured telephone interview. We found substantial differences in the distribution of ADHD subtypes depending on whether one or both sources were used to define the subtypes. When parent and teacher data were combined, the procedures used substantially influenced subtype distribution. We conclude the ADHD subtype distribution is sensitive to how symptom information is combined and that standardization of the subtyping process is required to advance our understanding of the correlates of different ADHD subtypes.     

Consultation with the Z Family's Technology Business: A Weekend Retreat

Family business consultation is an expanding enterprise and constitutes an interesting area of practice for psychologists drawn from industrial/organizational psychology, clinical psychology, and family psychology. This paper provides a clinical case example of a weekend retreat established as the forum for consultation to a family owned business that was experiencing a good deal of dissension between family and non-family management team members.     

Opportunities in public policy to support infant and early childhood mental health: the role of psychologists and policymakers

Infant and early childhood mental health practices can be supported by policies and professional standards of care that foster the healthy development of young children. Policies that support infants and toddlers include those that strengthen their families to provide a family environment that promotes mental wellness. Policy issues for infants, toddlers, and young children have come to the forefront of thinking as children need a "voice" to advocate for their support and care. This article (a) highlights several important policy areas that support the social-emotional development of very young children and (b) gives examples of current policy accomplishments and challenges. The article offers a policy agenda to promote the mental health of infants and young children and suggests ways that psychologists can engage with policymakers to promote policies that foster infant mental health, including contributing to the knowledge base that informs policy decisions, educating the public and policymakers about early childhood development and mental wellness, forming community partnerships to identify and address infant mental health risks, and participating in the development of policy recommendations that improve access to evidence-based practices in infant mental health.     

Perceived organizational support and employees’ well-being: the mediating role of organizational dehumanization

Perceived organizational support (POS) has been found to predict important organizational outcomes such as increasing employees’ well-being. In this research, we examine a new underlying mechanism of the relationship between POS and employees’ well-being, that is, employees’ perceptions that their organization dehumanizes them. This proposition was tested across two studies. Using an experimental design manipulating POS in a laboratory setting, Study 1 indicated that in the high POS condition, the subsequent feelings of being dehumanized by the organization were lower than in the low POS condition. More importantly, organizational dehumanization perceptions were found to mediate the POS condition and satisfaction link. Furthermore, using a sample of 1209 employees, results of Study 2 indicated that organizational dehumanization mediates the relationship between POS and three indicators of employees’ well-being (i.e., job satisfaction, emotional exhaustion, and psychosomatic strains). Implications for research on both organizational support theory and dehumanization theory are discussed.     

Natural,Artifactual, and Moral Goodness

In Natural Goodness, Philippa Foot (2001) aims to provide an account of moral evaluation that is both naturalistic and cognitivist. She argues that moral evaluation is a variety of natural evaluation in the sense that moral judgments of human action and character have the same “grammar” or “conceptual structure” as natural judgments of the goodness (e.g., health) of plants and animals. We argue that Foot’s naturalist project can succeed, but not in the way she envisions, because her central thesis that moral evaluation is a variety of natural evaluation is not entirely correct. We show that both moral and natural evaluation are species of kind evaluation, which encompasses moral, natural, and artifact evaluation. Kind evaluation is a form of evaluation, according to which things are evaluated qua members of a kind, in such a way that the kind into which something is classified informs the standards of evaluation (or norms) for things of that kind. Because the source of the normative standards for moral evaluation is different from the source of the normative standards for natural evaluation, moral evaluation is not a species of natural evaluation. However, both are varieties of kind evaluation. This account of moral evaluation as a variety of kind evaluation is still an effective response to non-naturalism and to non-cognitivism.     

Pre‐frontal‐insular‐cerebellar modifications correlate with disgust feeling blunting after subthalamic stimulation: A positron emission tomography study in Parkinson's disease

Subthalamic nucleus (STN) deep brain stimulation (DBS) has recently advanced our understanding of the major role played by this basal ganglion in human emotion. Research indicates that STN DBS can induce modifications in all components of emotion, and neuroimaging studies have shown that the metabolic modifications correlated with these emotional disturbances following surgery are both task‐ and sensory input‐dependent. Nevertheless, to date, these modifications have not been confirmed for all emotional components, notably subjective emotional experience, or feelings. To identify the neural network underlying the modification of feelings following STN DBS, we assessed 16 patients with Parkinson's disease before and after surgery, using both subjective assessments of emotional experience and ¹⁸[F]fluorodeoxyglucose positron emission tomography (¹⁸FDG‐PET). The patients viewed six film excerpts intended to elicit happy, angry, fearful, sad, disgusted, and neutral feelings, and they self‐rated the intensity of these feelings. After DBS, there was a significant reduction in the intensity of the disgust feeling. Correlations were observed between decreased disgust experience and cerebral glucose metabolism (FDG uptake) in the bilateral pre‐frontal cortices (orbitofrontal, dorsolateral, and inferior frontal gyri), bilateral insula, and right cerebellum. We suggest that the STN contributes to the synchronization process underlying the emergence of feelings.     

Imaging the Impact of Prenatal Alcohol Exposure on the Structure of the Developing Human Brain

Prenatal alcohol exposure has numerous effects on the developing brain, including damage to selective brain structure. We review structural magnetic resonance imaging (MRI) studies of brain abnormalities in subjects prenatally exposed to alcohol. The most common findings include reduced brain volume and malformations of the corpus callosum. Advanced methods have been able to detect shape, thickness and displacement changes throughout multiple brain regions. The teratogenic effects of alcohol appear to be widespread, affecting almost the entire brain. The only region that appears to be relatively spared is the occipital lobe. More recent studies have linked cognition to the underlying brain structure in alcohol-exposed subjects, and several report patterns in the severity of brain damage as it relates to facial dysmorphology or to extent of alcohol exposure. Future studies exploring relationships between brain structure, cognitive measures, dysmorphology, age, and other variables will be valuable for further comprehending the vast effects of prenatal alcohol exposure and for evaluating possible interventions.
