Efficacy of a Continuous Performance Test Based on Virtual Reality in the Diagnosis of ADHD and Its Clinical Presentations.

Objective: To analyze the diagnostic effectiveness of the AULA Nesplora test to discriminate the different ADHD presentations: impulsive/hyperactive (I/H), inattentive, and combined.Method: A total of 117 students (76.9% male and 23.1% female) between 5 and 16 years of age (M = 11.18 years, SD = 3.10 years) participated, and were divided into three groups with ADHD according to their presentation, and a control group. Results: Each of the test conditions allowed the discrimination between the I/H and combined presentations with respect to the control group, and between the I/H and inattentive presentations. However, differences among ADHD presentations were only evident when the results were separately analyzed for the visual and auditory modalities. Conclusion: This study showed that the indicators offered by the AULA Nesplora test (omissions, commissions, response times, and motor activity) make it possible to establish a differential diagnosis of ADHD presentations when analyzed under different contextual conditions.

State, Trait Anxiety and Selective Attention Differences in Attention Deficit Hyperactivity Disorder (ADHD) Subtypes

One of the disorders that most affects school performance is Attention Deficit Hyperactivity Disorder (ADHD). The criteria established by DSM distinguish three subtypes: inattentive, hyperactive-impulsive and combined. However, the expression of this disorder can be altered by its association with other disorders such as anxiety. The main goals of this study were to determine whether different patterns of attention (selective and concentration) and anxiety (state and trait anxiety) emerge from ADHD subtypes, and analyze how anxiety predicts the performance of students with ADHD in a selective attention task. The sample was made up of 220 children (6-12 years) divided into four groups: control group (n = 56), inattentive subtype (n = 54), hyperactive-impulsive subtype (n = 53), and combined subtype (n = 57). The results indicated that the groups differed significantly in the attention variables, and in state and trait anxiety. Multiple group comparisons revealed that the combined subtype exhibited higher trait anxiety, whereas the inattentive subtype showed more state anxiety. Additionally, trait anxiety predicted the students’ performance in the concentration variable of the attention task. These results suggest a novel path of significant interest concerning objective and reliable diagnostic assessment of ADHD.

New and Future Challenges Concerning the Use of Virtual Reality Tools for Assessing ADHD

IntroductionIn this short commentary, we highlight the changes in the conceptualization of ADHD from the perspective of the current main diagnostic systems (the DSM-5 and the imminent IDC-11) and their implications for the assessment/diagnosis of the disorder.ResultsWe provide a short review on the most widely known assessment methods available today, such as virtual reality tools, while also paying special attention to the ecological validity of these measures. Specifically, we describe new tools based on virtual reality, which has the potential to become a reliable, widely spread, and ecologically valid measure of ADHD.ConclusionsWhile measures using virtual reality tools have shown effectiveness in some previous studies, their characteristics, applicability, and future challenges concerning their use are presented here.

Parenting Style Dimensions As Predictors of Adolescent Antisocial Behavior

Antisocial behavior is strongly associated with academic failure in adolescence. There is a solid body of evidence that points to parenting style as one of its main predictors. The objective of this work is to elaborate a reduced, valid, and reliable version of the questionnaire by Oliva et al. (2007) to evaluate the dimensions of parenting style and to analyze its psychometric properties in a sample of Spanish adolescents. To that end, the designed questionnaire was applied to 1974 adolescents 12–18 years of age from Asturias (Spain). Regarding construct validity, the results show that the model that best represents the data is composed of six dimensions of parenting style, just as in the original scale, namely affection and communication; promotion of autonomy; behavioral control; psychological control; self-disclosure; and humor. The psychological control factor negatively correlates with the other factors, with the exception of behavioral control, with which it positively correlates. The remaining correlations among the factors in the parenting style questionnaire are positive. Regarding internal consistency, the reliability analysis for each factor supports the suitability of this six-factor model. With regard to criterion validity, as expected based on the evidence available, the six dimensions of parenting style correlate in a statistically significant manner with the three antisocial behavior measures used as criteria (off-line school aggression, antisocial behavior, and antisocial friendships). Specifically, all dimensions negatively correlate with the three variables, except for psychological control. In the latter case, the correlation is positive. The theoretical and practical implications of these results are discussed.

Naming speed as a predictive diagnostic measure in reading and attentional problems

ABSTRACT This study aimed to describe and compare naming speed abilities in children diagnosed with either Reading Learning Difficulties (RLD) or Attention Deficit/Hyperactivity Disorder (ADHD), or comorbidity for both (ADHD+RLD). To examine the explanatory power of naming speed and ADHD symptomatology in predicting group associations (while controlling for gender and age), the “Rapid Automatized Naming and Rapid Alternating Stimulus Tests” (RAN/RAS) were utilized. A sample of 101 children (age range = 5–16 years) was divided into four groups: RLD (n = 14), ADHD (n = 28), comorbid (n = 19), and control (n = 40). There were statistically significant differences in RAN/RAS results among the diagnostic groups. Moreover, discriminant analysis revealed that naming speed tasks significantly predicted reading and attentional problems, especially at earlier ages. These results demonstrate the potential usefulness of RAN/RAS in the diagnosis of reading and attentional problems, particularly if the children are aged from 5 to 9.

Effects of ADHD on writing composition product and process in school-age students

Objective: This study examined the relationship between ADHD and writing performance. Method: Students in Grades 3 to 7, 84 with ADHD and 135 age- and gender-matched controls completed a writing task (including process logs), and measures of working memory and attention. Results: Students with ADHD wrote texts of similar length but with poorer structure, coherence, and ideation. In all, 6.7% of the variance in writing quality was explained by whether or not the student had an ADHD diagnosis, after control for IQ and age-within-year, with ADHD students producing text that was less coherent, well structured, and ideationally rich, and spending less time thinking about and reviewing their text. Half of the effect on text quality could be attributed to working memory and sustained attention effects. Conclusion: ADHD has some effect on writing performance, which can, in part, be explained by working memory and attentional deficits.

Naming Speed and its effect on attentional variables and reading errors depending on the diagnosis

While naming speed, which is usually assessed with tests like RAN / RAS, has proven to be useful in predicting certain reading errors and attentional difficulties, the variables that predict performance in the test have not been examined yet. The objective of the present study is to test the explanatory power of certain reading and attentional variables on naming speed performance depending on the diagnosis. A sample of 132 students, divided into four groups (Control, n=34; Reading difficulties, n= 22; ADHD, n=41; and ADHD+Reading Difficulties, n=35) was used. The results show: 1) without any difficulties, naming speed is explained by IQ, age and gender; 2) in presence of reading difficulties, the variables with more explanatory power are the reading errors; 3) in presence of attentional difficulties, there are certain attentional variables like those provided by TOVA, which have shown to be more significant.

Analysis of cognitive and attentional profiles in children with and without ADHD using an innovative virtual reality tool

In previous studies, children with Attention-Deficit Hyperactivity Disorder (ADHD) have been found to have more difficulties with processing speed, working memory, and attentional tasks. The present study aimed to compare the cognitive variables (working memory and processing speed) and the attentional profiles of a sample of students with and without ADHD, using scales from the WISC-IV, and the virtual reality-based attentional test known as ‘Aula Nesplora’; and determine the extent to which the aforementioned variables may predict student group membership. A total of 88 students took part in this study (66 males and 22 females), aged from 6 to 16 years (M = 10.20; SD = 2.79). The sample was divided into two groups: an ADHD group (n = 50) and a Control group (n = 38). Students in the ADHD group obtained lower scores in working memory and in processing speed, as well as demonstrating poorer performance in Aula Nesplora than did their peers. Working memory, and the number of omissions, were both shown to be reliable predictors of group membership. This study revealed the importance of obtaining data from attentional variables differentiated by modality when considering cognitive variables, in order to better characterize the difficulties experienced by individuals diagnosed with ADHD.

Using Brain Activation (nir-HEG/Q-EEG) and Execution Measures (CPTs) in a ADHD Assessment Protocol

Attention Deficit Hyperactivity Disorder (ADHD) is a problem that impacts academic performance and has serious consequences that result in difficulties in scholastic, social and familial contexts. One of the most common problems in the identification of this disorder relates to the apparent over diagnosis of the disorder due to the absence of global protocols for assessment. The research group of School Learning, Difficulties and Academic Performance (ADIR) from the University of Oviedo, has developed a complete protocol that suggests the existence of certain patterns of cortical activation and executive control for identifying ADHD more objectively. This protocol takes into consideration some of the hypothetical determinants of ADHD, including the relationship between activation of selected areas of the brain, and differences in performance on various aspects of executive functioning such as omissions, commissions or response times, using innovative tools of Continuous Performance Testing (based on Virtual Reality CPT and Traditional CPT) and brain activation measures (two different tools, based on Hemoencephalography- nirHEG; and Quantified Electroencephalography --Q-EEG, respectively). This model of assessment aims to provide an effective assessment of ADHD symptomatology in order to design an accurate intervention and make appropriate recommendations for parents and teachers.

Teacher knowledge and attitudes towards inclusion: a cross-cultural study in Ghana, Germany and Spain

ABSTRACT Mainstream-school teachers are the most important assets for students with special educational needs (or diverse conditions) who hope to achieve real inclusion. However, teaching experience, attitudes, and knowledge can either promote or hinder efforts towards inclusion. A cross-cultural study was conducted to examine perceptions, knowledge, and attitudes towards inclusion in teachers from Ghana, Germany, and Spain, about intervention with special-education students enrolled in their classrooms. The participants comprised 363 teachers – 156 men (43%) and 207 women (57%) – from three countries (Ghana, Germany, and Spain). Of the teachers, 150 (41.3%) were from Ghana, 62 (17.1%) were from Germany, and 151 (41.6%) were from Spain. The results showed that there were significant differences in teachers’ self-confidence and in the amount of personal and material resources they received from administrators and schools. In general, the Spanish teachers reported lower levels for these variables. All the teachers showed adequate levels of knowledge about instructional strategies and students’ characteristics, although those from Ghana demonstrated significantly more knowledge than the others about students’ characteristics. Finally, the teachers differed by country in terms of their attitudes towards inclusion, with the teachers from Spain and Germany demonstrating slightly better attitudes. They all agreed on the need for additional training as a key aspect in this regard.
