The Positive Illusory Bias: Do ADHD Symptoms Differ Among Young Adolescents with Accurate Versus Discrepant Self-Perceptions?Fefer, Sarah A. 01 January 2011 (has links)
The purpose of this study was to gain insight into whether inattentive, hyperactive/ impulsive, and depressive symptoms differ among young adolescents with negative, accurate, or positive self-perceptions of their academic and social competence. Current literature suggests that elementary-age children with ADHD display overly positive self-perceptions, often referred to as the positive illusory bias (PIB; Owens, Goldfine, Evangelista, Hoza, & Kaiser, 2007). Self-reports of academic and social self-concept were compared to teacher ratings and test scores for 164 middle school students in an effort to determine if the PIB was present within this sample. Inattentive and hyperactive/impulsive symptoms were found to be significantly higher among the positive self-perception group in the academic domain with teacher ratings as the indicator of competence, while depressive symptoms were found to be significantly higher among the negative self-perception group. In the social domain, only inattentive symptoms were shown to be significantly higher in the positive self-perception group compared to the negative and accurate groups. Interestingly, there were no significant differences between groups with achievement test scores as the indicator of academic competence. These findings provide information about the PIB in young adolescents, an understudied group. Implications related to research and practice are also presented.

The Positive Illusory Bias and ADHD Symptoms: A New Measurement ApproachFefer, Sarah A. 01 January 2013 (has links)
The purpose of this study was to investigate perceptions of academic and social competence among adolescents with a continuum of inattentive and hyperactive/impulsive symptoms. Past literature suggests that children with Attention-Deficit/Hyperactivity Disorder (ADHD) display self-perceptions that are overly positive compared to external indicators of competence, a phenomenon that is referred to as the positive illusory bias (PIB; Owens, Goldfine, Evangelista, Hoza, & Kaiser, 2007). The PIB is well supported among children with ADHD, and recent research suggests that the PIB persists into adolescence. To date, research on the PIB has relied on difference scores (i.e., an indicator of competence is subtracted from student self-ratings); however, difference scores suffer from numerous methodological limitations (Edwards, 2002). The current study investigated the relationship between self and teacher ratings of academic and social competence and inattentive, hyperactive/impulsive, and overall ADHD symptoms among a diverse sample of 395 students and their teachers. Polynomial regression and response surface methods were used to account for self and teacher ratings separately and decrease reliance on differences scores. These methods have been recommended to answer complex questions related to agreement and disagreement between ratings. The results of this study suggest that some adolescents with ADHD symptoms demonstrate the PIB, while others perceive their impairments and rate themselves as having low competence aligned with teacher ratings. Accurate ratings of low competence were more common within the academic domain than the social domain for students with overall ADHD symptoms as well as specific inattentive and hyperactive/impulsive symptoms. Results within the social domain indicate that all ADHD symptoms increased more sharply as the discrepancy between self and teacher ratings increased. Student overestimation of competence in both the academic and social domains was shown to be more predictive of high inattentive symptoms compared to hyperactive/impulsive symptoms. These findings suggest this new analysis approach allowed for a more nuanced understanding of the complex relationship between student and teacher competence ratings and ADHD symptoms. Gaining a better understanding of the PIB through this improved methodology has the potential to influence assessment and intervention practices among school psychologists, and to contribute to future research in this area. This study contributes to the literature by being the first to (1) examine the PIB in relation to a range of general and specific ADHD symptoms, (2) use polynomial regression/response surface methods to address limitations of difference scores, and (3) explore the PIB among a school-based sample of adolescents.

Fluid reasoning, working memory and written expression of 9 to 14 year old children with attention deficit/hyperactivity disorderNaidoo, Reshma Babra 28 August 2008 (has links)
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalent conditions among school children. Executive function deficits representing difficulties in maintaining an appropriate problem set for the attainment of future goals are reported to be the major deficit in ADHD populations. There is a high rate of co-morbidity of learning disabilities and ADHD, with empirical evidence indicating an association with math and reading difficulties, but there is little research on the written expression of this population. There is a body of emergent research indicating that written expression is mediated by executive function. Written expression is a complex task that is affected by motivation, working memory, cognitive processes and long term memory, factors which are reported to be compromised in ADHD populations. This study evaluated the working memory and fluid reasoning in children with (combined and predominantly inattentive types) and without ADHD. Second, it explored the relationship between working memory and fluid reasoning on written expression in children with and without ADHD. Finally, the possible link between the executive functions of working memory and fluid reasoning, with written expression of children with and without ADHD was examined. The findings of this study indicate that children with the combined type of ADHD had lower written expression and working memory scores compared to children with the inattentive type of ADHD. The results of this study also indicated an association between disinhibition and working memory deficits on written expression performance. This research will serve to contribute to an understanding of the functional impact of ADHD on academic performance. Findings from this study could potentially help with interventions for deficits in written expression among school children.

The mediating effects of rapid automatized naming on children's inattention symptoms and word-reading abilitySmith, Stephen William, 1981- 22 June 2011 (has links)
Attention Deficit/Hyperactivity Disorder (ADHD) and Reading Disability (RD) are among the most common childhood disorders (American Psychiatric Association, 2000) and co-occur significantly more frequently than expected by chance (Dykman & Ackerman, 1991; Semrud-Clikeman et al., 1992). Similar processing deficits are seen in children with ADHD and children with RD, one of which is rapid automatized naming (RAN) (Denckla & Cutting, 1999). These continuous performance tasks require quick naming of visually represented stimuli. Uncertainty about what RAN actually measures, however, makes drawing conclusions about relations to ADHD and RD difficult (Tannock, 1998). By better understanding the cognitive processes involved in RAN, and how those processes relate to ADHD and RD symptoms, the relations among RAN, ADHD, and RD might be better understood.
The current study sought to identify variables that would help explain ADHD and RD children’s difficulty with RAN. Five fundamental, neurocognitive skills were hypothesized to be related to RAN performance, ADHD, and reading disability. The effect of children’s phonological awareness, processing speed, working memory, fine-motor speed, and reaction time on their RAN performances was measured. The extent to which these same variables were related to inattention symptoms severity and word-reading ability was also assessed. Finally, the extent to which RAN mediated the effects of neurocognitive skills on inattention symptoms and word-reading ability was measured. By simultaneously measuring the hypothesized relations among variables, the processing deficits responsible for ADHD and RD children’s problems on RAN may be revealed.
Structural equation modeling was used to analyze assessment data (i.e., neurocognitive, RAN, and word-reading performance scores; parent-report of inattention symptoms) of 183 children who received neuropsychological evaluations. Results indicated the following significant direct effects: phonological awareness and working memory on word-reading ability, processing speed and working memory on RAN, and RAN on word-reading ability. A possible significant mediation effect of processing speed on word-reading ability through RAN was also shown. Significant effects of study variables on inattention symptoms were not shown, which limited conclusions about RAN’s relation to ADHD. Results are of practical importance in RD assessment because the relation between RAN and word-reading ability was shown to involve processes beyond phonology. / text

Occupation-based and occupation-focused evaluation and intervention with children : a validation study of the assessment of motor and process skills (AMPS)Gantschnig, Brigitte Elisabeth January 2014 (has links)
Introduction Occupational therapists are concerned with enabling people to perform the daily life tasks they need, want, or are expected to perform for fullest possible integration into community living and participation in society. Children with mild disabilities have problems performing personal and instrumental activities of daily living (ADL) tasks at home or school, and that can limit their full integration and participation in their homes and school lives. There is a need, therefore, to identify their specific problems with ADL task performance so as to be able to develop effective interventions. Not only, there is a need for evidence related to effectiveness of occupational therapy interventions for children with mild disabilities, but also a need for valid occupational-therapy-specific evaluation tools for use with children. Purpose The purpose of this thesis was to contribute evidence to support the valid use of the Assessment of Motor and Process Skills (AMPS) with children, including children living in Middle Europe. More specifically, I aimed to evaluate validity evidence from different sources related to the use of the AMPS in occupation-based and occupation-focused evaluation and intervention. Method This thesis consisted of four studies, implemented in two phases. Phase one focused on evaluation of a) validity evidence of the AMPS scales in relation to internal structure and stability of item difficulty calibration values for a Middle European sample compared to samples from other world regions (Study I); b) the stability of the mean AMPS measures between typically-developing children from Middle Europe and from other world regions (Study II); and c) the sensitivity of the AMPS measures to discriminate between typically-developing children and children with and at risk for mild disabilities (Study III). Participants for phase one were from both Middle Europe and from other world regions and they were selected from the AMPS database, Ft. Collins, Colorado, USA. Data were analyzed using many-facet Rasch analyses, ANOVAs, regression analyses, related post-hoc tests, and effect size calculations. Phase two of the research project focused on evaluating validity evidence for the use of the AMPS as a standardized, occupation-based, and occupation-focused evaluation tool in the context of a feasibility study with children with mild disabilities implemented in a Swiss setting (Study IV). Data were analyzed based on feasibility objectives and the principles of deductive content analysis. The evaluation of validity evidence of the AMPS in relation to consequences of testing and test fairness was a focus of all studies (Studies I to IV). Results In Study I, data for 1346 participants from Middle Europe and 144,143 participants from other world regions were analyzed. The participants were between the ages of 3 and 103 years, and they were well or had a variety of diagnoses. The results revealed that overall the item difficulty calibration values of the AMPS remained stable and that only one out of 36 ADL items of the AMPS demonstrated DIF, but this DIF did not lead to DTF (i.e., all measures fell within 95% confidence bands). In Study II, data for 11,189 typically-developing children from Middle Europe and other world regions who were between the ages of 2 and 15 were analyzed. The results of ANOVAs revealed significant effects for mean ADL motor and for ADL process ability measures by region and a significant age by region interaction effect for mean ADL process ability. Out of 168 estimated contrasts between Middle Europe and the other world regions for mean ADL motor and ADL process ability, only seven were statistically significant (4.17%), and only two were more than ±1 SE from the international means. In Study III, regression analyses of data for 10,998 children, 4 to 15 years, who were typically-developing or with mild disabilities, revealed significant age by group interaction effects. Post hoc t tests revealed significant group differences in ADL ability at all ages beyond the age of 4. ADL process ability effect sizes were moderate to large at all ages and ADL motor ability effect sizes were mostly moderate to large age 6 and above. In Study IV, the use of the AMPS within the context of a feasibility study based on data of 17 Swiss children with mild disabilities was evaluated. The analyses revealed several strengths and problems that were related to the time, equipment, and materials for administering the AMPS, the adherence to standardized administration procedures, the scope of the AMPS as a test of ADL performance, and the reliable rating by the blinded rater. Conclusion This thesis provided evidence to support the validity of the AMPS measures and scales when used to evaluate quality of ADL task performance of persons from Middle Europe. Additionally, this thesis provided evidence that the international age-normative means of the AMPS are likely applicable to children from Middle Europe. Moreover, the findings supported the sensitivity of the AMPS measures to discriminate between typically-developing children and children with and at risk for mild disabilities. When it comes to implementation of the AMPS in the context of a feasibility study, the findings indicated both strengths and problems in using the AMPS as an outcome measure that need to be considered when planning further studies.
