Working memory functioning in children with predominantly Inattentive Attention Deficit/Hyperactivity Disorder (ADHD) versus children with predominantly hyperactive ADHD

Allsopp, Karen Margaret 27 January 2009 (has links)
Abstract Working memory has been identified as an area in which children diagnosed with ADHD experience difficulty (Carnoldi, Marzocchi, Belotti, Caroli, De Meo & Braga, 2001). However, there are conflicting findings regarding the nature of working memory deficits in children diagnosed with ADHD and some researchers believe that working memory deficits may differ between the two ADHD subtypes (Diamond, 2005; Douglas, 2005; Knouse 2007; Milich , Balentine & Lynam, 2001). In addition, it is also thought that working memory may be one of the main contributing factors of this disorder (Rapport, Chung, Shore & Isaacs, 2001). Thus, there is clearly a need for additional and more detailed investigation into the way individuals with ADHD test with regard to their working memory functioning. This study attempted to examine the working memory functioning in children diagnosed with ADHD, in particular, the Predominantly Inattentive subtype and Predominantly Hyperactive/impulsive subtype in comparison to a control group. A sample of seventy-two participants was tested using the Ravens Progressive Coloured Matrices (RPCM) and the Automated Working Memory Assessment (AMWA) to assess their nonverbal intelligence and working memory. The primary motivating factor for the choice of participants was that they had to have been diagnosed by a professional as having ADHD (either subtype) and they had to be in Grades one or two. None of the children in the control group met the DSM-IV-TR (APA, 2000) criteria for ADHD.

None of the children in the control group met the DSM-IV-TR (APA, 2000) criteria for ADHD. Repeated measures of Mann-Whitney and post-hoc analysis revealed that there were significant differences in the verbal short term memory, verbal working memory and visuospatial working memory between the three groups. Test results revealed no significant differences between the test scores of the Inattentive group and the control group in these areas. However, scores obtained by the Hyperactive/impulsive group differed significantly from those of the control and Inattentive groups. Score differences related specifically to verbal short term memory, verbal working memory and visuospatial working memory. This implies that children diagnosed with ADHD, (the Hyperactive/impulsive subtype) may need specific strategies in the classroom to enable them to encode, access and retrieve information to ensure optimal performance. The implications of these findings are discussed further in the thesis.

Peer Victimization in Adolescents with Attention-deficit/Hyperactivity Disorder: Frequency and Risk Factors

Timmermanis, Victoria 01 January 2011 (has links)
The present study examined the frequency and risk factors associated with experiencing victimization by peers and bullying others in adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). Sixty-four males and females (ages 13-18) and their parents and teachers completed standardized questionnaires. Adolescents with ADHD were more likely to report increased levels having experienced victimization by peers and participation in bullying others. Parent reports of victimization by peers and bullying others did not differ between adolescents with and without ADHD. Among adolescents with ADHD, those who had experienced victimization by peers perceived lower levels of social support and had increased levels of parent-reported peer relation difficulties. Bullying others was not associated with perceptions of social support or parent-reported peer relation problems. Individual factors such as internalizing problems and oppositionality were not significantly associated with experiencing victimization by peers or bullying others. Implications for future research and clinical assessment are discussed.

The Impact of Mindfulness Training on Hyperactive Behaviors Demonstrated by Elementary Age Children with a Diagnosis of Attention Deficit Hyperactivity Disorder

Carboni, Jessica A 11 May 2012 (has links)
Attention Deficit / Hyperactivity Disorder (ADHD) is one of the most prevalent childhood disorders in the United States. Although many children with an ADHD diagnosis are prescribed medication to control symptoms, behavioral concerns are still regularly noted in the classroom, home, and other settings. Therefore, school psychologists are often called upon to assist teachers and families with developing intervention procedures. The purpose of this research was to investigate the relationship between mindfulness training, the cognitive processes of attention regulation, and behavior of children who have been diagnosed with ADHD. This study utilized a multiple baseline across participant’s design where each student was tracked over time following a baseline (pre-intervention) condition. Four 8-year-old male participants with a primary diagnosis of ADHD and a significant number of off-task classroom behaviors were included in this study. Teacher and parent ratings of the Behavior Assessment System for Children, Second Edition (BASC-2) and Behavior Rating Inventory of Executive Function (BRIEF) were completed pre- and posttest for each participant. The Reliable Change Index (RCI) was calculated to determine if the pre- to posttest change scores on the BASC-2 and BRIEF exceeded what could be accounted for by measurement error alone. Results of the analyses revealed that mindfulness training was effective in increasing the number of on-task behaviors for participants. Parent and teacher ratings on the BRIEF suggest that mindfulness training impacted ratings on the Inhibit, Initiate, and Monitor scales. Parent and teacher ratings on the BASC-2 were analyzed and scores from the Attention Problems scale did not demonstrate significant change across raters and across participants. Significant change occurred on the Hyperactivity scale. Findings are discussed in relationship to the literature on mindfulness training for students with a diagnosis of ADHD. Implications for future research and practice are also suggested.
