The Effects of Weight Loss Attempts, Exercise Initiation, and Dietary Practices on Health Related Quality of Life

This study (N = 98) randomly placed participants in either a higher protein or American Heart Association diet group with each group initiating an aerobic exercise program. Body composition (BC) was measured using four different methodologies (DEXA, BIA, skinfold, BMI) along with height and weight, while Health-Related Quality of Life (HRQOL) changes were measured using the Medical Outcomes Short Form 36 (SF-36). There were no significant time/diet interactions in HRQOL scores, body fat measures, and weight with the exception of Role-Physical scores (p = .006) with posttest scores higher in participants in Diet 1. Role-Physical scores changed significantly in participants in Diet 1 (p = .0001) and Diet 2 (p = .026) with higher posttest scores in each group. Social functioning had a significant main effect for time in both groups with pretest scores in both diet groups lower than their respective posttest scores (p = .015). HRQOL pretest scores were not significantly different between groups at baseline (p = .56). ANOVA revealed no significant differences in average calories between groups (p = .88). Analysis revealed no differences in exercise in minutes (p = .66) nor statistically significant changes in BC or weight (p = .65). Conclusions: Improvements in HRQOL were demonstrated in two subscales related to physiological and psychological functioning. These novel findings add to literature suggesting that HRQOL, at least concerning social functioning, work and other daily activities (Role-Physical) may improve by initiating an exercise and dietary program even when weight loss or BC improvements have been unsuccessful.     

Affect, Social Behavior, and the Brain in Williams Syndrome

ABSTRACT— Williams syndrome (WS) is a rare genetic disorder characterized by intellectual impairment and a distinctive physical and neuropsychological profile. Relative to their level of intellectual functioning, individuals with WS exhibit strengths in language and face recognition, with deficits in visual-spatial cognition. A heightened appetitive drive toward social interaction is a strong behavioral feature. Relative to other neurodevelopmental disorders, WS has a clearly defined genetic basis, together with a consistent neurocognitive profile of strengths and deficits. Thus, this disorder offers unique opportunities for elucidating gene–brain–behavior relationships. We focus on manifestations of the unusual social profile in WS, by examining data within and across levels of cognition, brain, and molecular genetics.     

Using information theory to assess the diversity,complexity, and development of communicative repertoires

The application of quantitative and comparative measures from information theory on animal communication can provide novel insights into the ecological, environmental, social, and contextual properties that shape the structure, organization, and function of signal repertoires. Using 2 phylogenetically different mammalian species that share similar ecological and social constraints as examples, the authors quantitatively examined the internal structure and development of a subsystem of these species' vocal repertoires in comparison with that of human language and illustrated that these species exhibit convergent developmental processes. The authors also discussed how predictions on the structure and organization of animal communication systems can be made from this new application of information theoretic measures with respect to behavioral ecology.     

Developmental profiles of peer social preference over the course of elementary school: associations with trajectories of externalizing and internalizing behavior

Using a new longitudinal clustering technique, this study aimed to (a) empirically identify groups of children with distinct longitudinal profiles of peer social preference during elementary school; (b) compare these groups regarding their longitudinal pattern of classification into J. D. Coie, K. A. Dodge, and H. Coppotelli's (CDC; 1982) sociometric categories; and (c) compare these groups regarding their longitudinal trajectories of antisocial, hyperactive, and anxious behavior. Based on 299 children, 3 groups were identified: a stable popular group, a stable average group, and an unpopular group whose social preference decreased over time. Each of the groups showed considerable overlap over time with their closest corresponding CDC category (popular, average, rejected). Growth curve analyses showed that externalizing and internalizing behavior generally decreased over time, but overall means and the rates of decrease differed in the 3 groups.     

Direct and interactive effects of parent,friend and schoolmate drinking on alcohol use trajectories

Objective: This study considered the unique and interactive roles of social norms from parents, friends and schools in predicting developmental trajectories of adolescent drinking and intoxication.

Design and outcome measures: Using data from the National Longitudinal Study of Adolescent Health, which followed adolescents (N = 18,921) for 13 years, we used discrete mixture modelling to identify unique developmental trajectories of drinking and of intoxication. Next, multilevel multinomial regression models examined the role of alcohol-related social norms from parents, friends and schoolmates in the prediction of youths’ trajectory group membership.

Results: Results demonstrated that social norms from parents, friends and schoolmates that were favourable towards alcohol use uniquely predicted drinking and intoxication trajectory group membership. Interactions between social norms revealed that schoolmate drinking played an important moderating role, frequently augmenting social norms from parents and friends. The current findings suggest that social norms from multiple sources (parents, friends and schools) work both independently and interactively to predict longitudinal trajectories of adolescent alcohol use.

Conclusions: Results highlight the need to identify and understand social messages from multiple developmental contexts in efforts to reduce adolescent alcohol consumption and alcohol-related risk-taking.

Can the home environment promote resilience for children born very preterm in the context of social and medical risk?

Relationships between the home environment and early developmental outcomes were examined in 166 children born very preterm in one tertiary maternity hospital to explore whether a more optimal home environment could promote resilience. In particular, we explored whether this effect was apparent over and above social risk and children's biological risk, as measured by cerebral white matter abnormality (WMA) evaluated using magnetic resonance imaging (MRI) at term-corrected age and length of hospital stay (LOS), and whether the effect of the home environment differed according to WMA. The home environment and social-emotional outcomes were assessed at 2years' corrected age using the Home Screening Questionnaire (HSQ) and the Infant-Toddler Social and Emotional Assessment (ITSEA). Children's cognitive and motor development was assessed using the Bayley Scales of Infant Development II. A more optimal home environment was associated with better cognitive and social-emotional development after adjusting for social risk, WMA, and LOS. Neonatal cerebral WMA moderated the relationship between the home environment and dysregulation problems only, such that the home environment had less effect on dysregulation for children with mild or moderate to severe WMA. The need to support parents to create an optimal home environment is discussed.     

Operationalizing the Assessment and Management of Violence Risk in the Short-term

Assessing risk of violence in the short term is crucial for managing and preventing violence, especially in institutions such as psychiatric units and prisons. Despite a lack of consensus on the definition of "short term", a number of recent tools and guidelines have been developed to aid short-term clinical decision-making. Whereas the supporting evidence for the new tools is impressive, limitations remain in terms of the focus on prediction, limited consideration of strengths, and poor integration with formulation and risk management. The Short-Term Assessment of Risk and Treatability (START) is a brief clinical guide for the dynamic assessment of risks, strengths and treatability. It focuses on short-term risks and the characteristics of the individual that, if changed, might lead to an increase or decrease in risk. The START has the potential to operationalize the structured professional judgment (SPJ) approach in order to inform the evaluation of multiple risk domains relevant to everyday psychiatric clinical practice. However, explicit guidance on integrating risk assessment, formulation and management is limited in the START and this paper describes the SPJ approach, reviews recent developments in approaches to risk, and considers how the START can be used to inform SPJ approaches and link risk assessment, formulation, and management.
