The Efficacy of Head-Mounted-Display Virtual Reality Intervention to Improve Life Skills of Individuals with Autism Spectrum Disorders: A Systematic Review.

Challenges in life skills in individuals with autism spectrum disorders (ASD) are associated with dependency on others and increased isolation from peers. In recent years, interventions using virtual reality (VR) technology have been proposed to improve life skills in ASD populations. This systematic review seeks to evaluate the efficacy of employing VR interventions mediated via head-mounted displays (HMD) for the improvement of life skills in individuals with ASD. Several databases were searched and a narrative synthesis was conducted to examine the findings of the included studies. Eight studies including a total of 58 participants were deemed relevant for this systematic review. The methodological quality of the included studies was assessed via the use of critical appraisal tools. Results were generally positive, with one study reporting statistically significant results, and one study not reporting any change in abilities. The remaining six studies reported varying degrees of life skill improvement. The studies were characterized by methodological issues, such as very low sample sizes. The findings of this systematic review indicate some potential for HMD VR interventions in the improvement of life skills in individuals with ASD. However, this review also highlights the current lack of methodologically strong study designs, which prohibits any firm conclusions. Findings are discussed regarding methodological recommendations for further research as well as practical implications for life skills interventions for individuals with ASD.

Beer advertisements and adolescent drinking knowledge, expectancies, and behavior.

OBJECTIVE: (1) To examine the degree to which overall beer advertising expenditure is related to youth brand awareness, preferences, and drinking behavior, and (2) to use multiple methods, including individual brand awareness and expectancies, to gain a broader understanding of the effects of alcohol advertising on youth alcohol-related expectancies and behavior. METHOD: Mixed psychological and advertising methods were used to examine how beer advertising is related to adolescents' beer brand awareness, expectancies, and behavior. 1588 7-12th graders were surveyed in two U.S. states. RESULTS: The amount of money spent advertising beer brands was positively correlated with adolescents' brand awareness, preference, use, and loyalty behavior (all correlations above 0.65). Moreover, beer advertising-related variables predicted adolescents' intention to drink and actual alcohol consumption, independent of peer and parent alcohol-related behavior and attitudes. CONCLUSIONS: The results show that overall levels of advertising expenditures were strong predictors of adolescents' beer brand awareness, preferences, use, and brand loyalty. Moreover, advertising-related variables were substantial predictors of adolescents' intention to drink as an adult and current underage drinking behavior. Together, the present findings suggest that previous work may have underestimated the relationship between alcohol advertising and adolescents' drinking behavior.

The effects of violent media content on aggression.

Decades of research have shown that violent media exposure is one risk factor for aggression. This review presents findings from recent cross-sectional, experimental, and longitudinal studies, demonstrating the triangulation of evidence within the field. Importantly, this review also illustrates how media violence research has started to move away from merely establishing the existence of media effects and instead has begun to investigate the mechanisms underlying these effects and their limitations. Such studies range from investigations into cross-cultural differences to neurophysiological effects, and the interplay between media, individual, and contextual factors. Although violent media effects have been well-established for some time, they are not monolithic, and recent findings continue to shed light on the nuances and complexities of such effects.

Emotion Understanding in Clinically Anxious Children: A Preliminary Investigation.

Children's understanding of the nature, origins and consequences of emotions has been intensively investigated over the last 30-40 years. However, few empirical studies have looked at the relation between emotion understanding and anxiety in children and their results are mixed. The aim of the present study was to perform a preliminary investigation of the relationships between emotion understanding, anxiety, emotion dysregulation, and attachment security in clinically anxious children. A sample of 16 clinically anxious children (age 8-12, eight girls/boys) was assessed for emotion understanding (Test of Emotion Comprehension), anxiety (Screening for Child Anxiety Related Emotional Disorders-Revised and Anxiety Disorder Interview Schedule), emotion dysregulation (Difficulties in Emotion Regulation Scale) and attachment security (Security Scale). Children who reported more overall anxiety also reported greater difficulties in regulating their emotions, and were less securely attached to their parents. The results also showed that more specific symptoms of anxiety (i.e., OCD and PTSD) correlated not only with emotion dysregulation and attachment insecurity but also with emotion understanding. Finally, there were interrelations among emotion understanding, attachment security, and emotion dysregulation. The present results provide the first comprehensive evidence for a socio-emotional framework and its relevance to childhood anxiety.

The impact of abuse and learning difficulties on emotion understanding in late childhood and early adolescence.

Children's affective experiences and cognitive abilities have an impact on emotion understanding. However, their relative contribution, as well as the possibility of an interaction between them, has rarely been examined. The aim of the present study was to evaluate the influence of severe abuse and learning difficulties on simple and complex components of emotion understanding in late childhood and early adolescence. A total of 28 older children and young adolescents were selected for the study. Half of the participants had suffered from severe abuse, and half of these abused children additionally had learning disabilities. The remaining half of the sample had no history of abuse but were matched with the abused children on learning difficulties, age and gender. The participants' emotion understanding was assessed with the Test of Emotion Comprehension (TEC). Results showed that (a) learning difficulties but not abuse had an impact on emotion understanding, (b) there was no interaction effect of abuse and learning difficulties on emotion understanding, and (b) the observed effects of learning difficulties were most apparent for the understanding of relatively complex components of emotion and not for simple components. The results are discussed in terms of their theoretical and practical implications.

A structural assessment of the 30-item Metacognitions Questionnaire for Children and its relations to anxiety symptoms.

Theoretical models of anxiety have been developed in adult populations. The applicability of these models in child samples has been assessed using downward extensions of the questionnaires developed to assess the proposed theoretical mechanisms. This poses a challenge, as children are still in the process of developing the skills that are being assessed. Psychometrically sound assessment tools are therefore needed for this developing population, in order to ensure the early detection of mechanisms leading to anxiety disorders in children. This study examined if metacognitions, which play a key role in generalized anxiety disorder (GAD) in adults, can also be reliably assessed in childhood. The study investigated the psychometric properties of the 30-item Metacognitions Questionnaire for Children (MCQ-C30; Gerlach, Adam, Marschke, & Melfsen, 2008) in a national sample of 974 children and adolescents (538 girls) ages 9-17 years. Confirmatory factor analysis supported the 5-factor subscale structure and a 2nd-order total scale factor, which corresponds with previous versions of the scale. MCQ-C30 expectedly correlated significantly with anxiety symptoms and worry. Structural equation modeling revealed that both obsessive-compulsive disorder and generalized anxiety disorder symptoms regressed significantly onto the MCQ-C30. We fitted separate models for children and adolescents, and no noticeable differences are suggested between the models. Female gender was, expectedly, associated with increased levels of general metacognitions. This gender effect was mediated by level of anxiety. Overall, the MCQ-C30 exhibited acceptable psychometric properties in our community sample of children ages 9-17 years. Future studies should investigate the psychometric properties of the instrument in clinical samples and samples of younger children.

TaqMan genotyping of insertion/deletion polymorphisms.

The 5' fluorogenic (TaqMan) assay has been successfully used in screening for single-nucleotide polymorphisms; the very few steps required and the ability to automate each step allow for high-throughput screening. Insertion/deletion polymorphisms are an important class of markers that can be studied for different applications, such as diagnostics, genome variation, and species identification. Polymerase chain reaction (PCR) and post-PCR analysis are required to score the insertion or the deletion allele. In this chapter, we describe an expansion of the TaqMan technology for a rapid, high-throughput, screening for insertion/deletion polymorphisms in which the exact endpoints are known. The method requires minimal post-PCR analysis and can be applied to polymorphisms of any size.
