Tracking Effects of Problematic Social Networking on Adolescent Psychopathology: The Mediating Role of Sleep Disruptions.

Concerns are growing about adolescents' problematic social networking and possible links to depressed mood and externalizing behavior. Yet there remains little understanding of underlying processes that may account for these associations, including the mediating role of sleep disruption. This study tests this putative mediating process and examines change in problematic social networking investment and disrupted sleep, in relation to change in depressed mood and externalizing behavior.

The essence of crime: Contagious transmission from those who have committed moral transgressions.

Across four studies, we investigated the relationship between moral contagion and disgust. Study 1 established that the contamination effect is unique to transgressions that fall within the moral domain. Study 2 replicated this effect and further showed that the underlying mechanism is intimately related to disgust, as disgust was found to uniquely mediate the relationship between moral transgressions and contamination responses.

A brief intervention to increase physical activity behavior among adolescents using mental simulations and action planning.

This study evaluated the effectiveness of a brief integrated theory-based intervention to increase physical activity (PA) among adolescents over a three-month follow-up period. A 2 (mental simulation: present vs. absent) × 2 (action planning: present vs.

The etiology of social anxiety disorder: An evidence-based model.

The current paper presents an update to the model of social anxiety disorder (social phobia) published by Rapee and Spence (2004). It evaluates the research over the intervening 11 years and advances the original model in response to the empirical evidence. We review the recent literature regarding the impact of genetic and biological influences, temperament, cognitive factors, peer relationships, parenting, adverse life events and cultural variables upon the development of SAD.

Brief intensive CBT for pediatric OCD with E-therapy maintenance.

Cognitive behaviour therapy (CBT), incorporating exposure and response prevention (ERP), has received strong empirical support for the treatment of paediatric OCD, and moreover, is considered the first line treatment of choice (Geller & March, 2012). However, despite the availability of effective treatments for this chronic and debilitating disorder, only a small proportion of youth receive these evidence-based approaches. The present study aimed to examine the effectiveness of an intensive ERP-based treatment for youth OCD, using a multiple baseline controlled design.

Using meta-analytic path analysis to test theoretical predictions in health behavior: An illustration based on meta-analyses of the theory of planned behavior.

Objective: Synthesizing research on social cognitive theories applied to health behavior is an important step in the development of an evidence base of psychological factors as targets for effective behavioral interventions. However, few meta-analyses of research on social cognitive theories in health contexts have conducted simultaneous tests of theoretically-stipulated pattern effects using path analysis. We argue that conducting path analyses of meta-analytic effects among constructs from social cognitive theories is important to test nomological validity, account for mediation effects, and evaluate unique effects of theory constructs independent of past behavior.

Stress exposure and generation: A conjoint longitudinal model of body dysmorphic symptoms, peer acceptance, popularity, and victimization.

This study examined the bidirectional (conjoint) longitudinal pathways linking adolescents' body dysmorphic disorder (BDD) symptoms with self- and peer-reported social functioning. Participants were 367 Australian students (45.5% boys, mean age=12.

ADHD subtypes and neuropsychological performance in an adult sample.

The study investigated, with an adult sample, the hypothesis that differences between subtypes of ADHD on neuropsychological tests contribute to the poor separation of ADHD and healthy groups on tests of this kind. Groups of ADHD inattentive (n=16) and combined (n=16) subtypes were carefully identified using DSM-IV criteria, and their performance on 14 measures of attention, memory, and executive function (EF) was compared between subtypes and between the two subtypes combined and a group of healthy controls (n=30). Multivariate analyses showed statistically significant differences between the two subtypes, and between the two subtypes combined and the healthy controls.

Simulation based virtual learning environment in medical genetics counseling: an example of bridging the gap between theory and practice in medical education.

Background: Simulation based learning environments are designed to improve the quality of medical education by allowing students to interact with patients, diagnostic laboratory procedures, and patient data in a virtual environment. However, few studies have evaluated whether simulation based learning environments increase students' knowledge, intrinsic motivation, and self-efficacy, and help them generalize from laboratory analyses to clinical practice and health decision-making.

Methods: An entire class of 300 University of Copenhagen first-year undergraduate students, most with a major in medicine, received a 2-h training session in a simulation based learning environment.

A randomized controlled trial of an audio-based treatment program for child anxiety disorders.

The aim of this study was to investigate the efficacy of an audio-based cognitive-behavioural therapy (CBT) program for child anxiety disorders. Twenty-four children aged 5-11 years were randomly allocated into either the audio-based CBT program condition (Audio, n = 12) or a waitlist control (WL; n = 12) group. Outcome measures included a clinical diagnostic interview, clinician-rated global assessment of functioning, and parent and child self-report ratings of anxiety and internalisation.

A qualitative study exploring health perceptions and factors influencing participation in health behaviors in colorectal cancer survivors.

Purpose: The purpose of the study was to explore colorectal cancer survivors' health perceptions following cessation of active treatment for cancer and to explore the factors influencing participation in health-promoting behaviors that may help reduce cardiovascular disease risk.

Methods: Face-to-face interviews were conducted with participants that had completed active treatment for cancer within the previous 2 years. Participants were colorectal cancer survivors (N = 24, men = 11, women = 13, M age = 69.

Independence of Hot and Cold Executive Function Deficits in High-Functioning Adults with Autism Spectrum Disorder.

Individuals with autistic spectrum disorder (ASD) display diverse deficits in social, cognitive and behavioral functioning. To date, there has been mixed findings on the profile of executive function deficits for high-functioning adults (IQ > 70) with ASD. A conceptual distinction is commonly made between "cold" and "hot" executive functions.

Implementation intention and planning interventions in Health Psychology: Recommendations from the Synergy Expert Group for research and practice.

The current article details a position statement and recommendations for future research and practice on planning and implementation intentions in health contexts endorsed by the Synergy Expert Group. The group comprised world-leading researchers in health and social psychology and behavioural medicine who convened to discuss priority issues in planning interventions in health contexts and develop a set of recommendations for future research and practice. The expert group adopted a nominal groups approach and voting system to elicit and structure priority issues in planning interventions and implementation intentions research.

The profile of psychiatric symptoms exacerbated by methamphetamine use.

Background: Methamphetamine use can produce symptoms almost indistinguishable from schizophrenia. Distinguishing between the two conditions has been hampered by the lack of a validated symptom profile for methamphetamine-induced psychiatric symptoms. We use data from a longitudinal cohort study to examine the profile of psychiatric symptoms that are acutely exacerbated by methamphetamine use.

A Longitudinal Rejection Sensitivity Model of Depression and Aggression: Unique Roles of Anxiety, Anger, Blame, Withdrawal and Retribution.

In this longitudinal study, attributional and social processes involved in symptoms of mental health problems (depressive symptoms and aggressive behavior) were identified by investigating anxious and angry rejection sensitivity (RS), causal attributions of self-blame and peer-blame, and responses to rejection threat of withdrawal and retribution. Young adolescents (N = 713, grades 5-7) completed questionnaires three times in their regular classrooms over 14 months. Participants who reported more self-blame for rejection were more likely to withdraw in response to rejection threat, and withdrawal and anxious RS were associated with increased depressive symptoms at T3 relative to T1.

Cluster randomised-control trial for an Australian child protection education program: Study protocol for the Learn to be safe with Emmy and friends™.

Background: Child maltreatment has severe short-and long-term consequences for children's health, development, and wellbeing. Despite the provision of child protection education programs in many countries, few have been rigorously evaluated to determine their effectiveness. We describe the design of a multi-site gold standard evaluation of an Australian school-based child protection education program.

A Longitudinal Study of Sexual Entitlement and Self-Efficacy among Young Women and Men: Gender Differences and Associations with Age and Sexual Experience.

Many scholars have called for an increased focus on positive aspects of sexual health and sexuality. Using a longitudinal design with two assessments, we investigated patterns of entitlement to sexual partner pleasure and self-efficacy to achieve sexual pleasure among 295 young men and women aged 17-25 years attending one Australian university. We also tested whether entitlement and efficacy differed by gender, and hypothesized that entitlement and efficacy would be higher in older participants and those with more sexual experience.

A preprocessing tool for removing artifact from cardiac RR interval recordings using three-dimensional spatial distribution mapping.

Artifact is common in cardiac RR interval data that is recorded for heart rate variability (HRV) analysis. A novel algorithm for artifact detection and interpolation in RR interval data is described. It is based on spatial distribution mapping of RR interval magnitude and relationships to adjacent values in three dimensions.

Predicting Self-Management Behaviors in Familial Hypercholesterolemia Using an Integrated Theoretical Model: the Impact of Beliefs About Illnesses and Beliefs About Behaviors.

Purpose: Patients with familial hypercholesterolemia (FH) are at markedly increased risk of coronary artery disease. Regular participation in three self-management behaviors, physical activity, healthy eating, and adherence to medication, can significantly reduce this risk in FH patients. We aimed to predict intentions to engage in these self-management behaviors in FH patients using a multi-theory, integrated model that makes the distinction between beliefs about illness and beliefs about self-management behaviors.

Is athletic really ideal? An examination of the mediating role of body dissatisfaction in predicting disordered eating and compulsive exercise.

Background: Investigations into female body image have suggested that rather than thinness, preference is now being given to a female "athletic ideal" characterised by a toned abdomen, firmer lower body and muscular upper body. This study sought to investigate a) whether greater internalization of the athletic-ideal is associated with higher body dissatisfaction, dieting, bulimic symptoms and compulsive exercise, and b) whether body dissatisfaction mediates the relationship between athletic-ideal internalization and the disordered eating and exercise behaviours of dieting, bulimic symptoms and compulsive exercise.

Methods: Participants were 388 females aged between 17 and 35years.

Investigation of the cognitive variables associated with worry in children with Generalised Anxiety Disorder and their parents.

Background: Intolerance of uncertainty (IU), negative beliefs about worry (NBW), positive beliefs about worry (PBW), negative problem orientation (NPO) and cognitive avoidance (CA) have been found to be integral in the conceptualisation of Generalised Anxiety Disorder (GAD) in adults, yet they have rarely been investigated in children with GAD. This study sought to determine (a) whether IU, NBW, PBW, NPO and CA differ between children diagnosed with GAD and non-anxious children and (b) to examine whether IU, NBW, PBW, NPO and CA differ between parents of children diagnosed with GAD and parents of children without an anxiety disorder.

Methods: Participants were 50 children (aged 7-12 years), plus one of their parents.

Measuring situational avoidance in older drivers: An application of Rasch analysis.

Situational avoidance is a form of driving self-regulation at the strategic level of driving behaviour. It has typically been defined as the purposeful avoidance of driving situations perceived as challenging or potentially hazardous. To date, assessment of the psychometric properties of existing scales that measure situational avoidance has been sparse.

A biopsychosocial investigation of changes in self-concept on the Head Injury Semantic Differential Scale.

This study aimed to investigate the influence of the "good-old-days" bias, neuropsychological functioning and cued recall of life events on self-concept change. Forty seven adults with TBI (70% male, 1-5 years post-injury) and 47 matched controls rated their past and present self-concept on the Head Injury Semantic Differential Scale (HISD) III. TBI participants also completed a battery of neuropsychological tests.
