Clustering of Behavioral Data for Identification of Presumptive Subtypes of Attention Deficit/Hyperactivity Disorder in Children

Taylor, Shannon E. 08 1900 (has links)
The objective of the present study was to investigate Amen's formulations of subtypes of AD/HD initially identified by brain imaging techniques, through the use of behavioral checklist data. And in testing Amen's theory of six separate subtypes of AD/HD, to identify and differentiate the subtypes based on symptom presentation. Data was obtained through retrospective chart reviews (N=161) of children between the ages of 5 and 12 who met the criteria for the major symptoms observed in AD/HD and were referred for a previous comprehensive AD/HD evaluation. Data from behavioral checklist (CBCL and DBRS-IV) were matched to Amen's Subtype Symptom Checklist and each subject was given a percentage score for six subtype symptoms. Cluster analysis reliably found six clusters and each subject was labeled according to their symptom presentation. The clusters found were labeled as AD/HD - Combined Type, AD/HD - Predominately Inattentive Type, AD/HD - Predominately Hyperactive-Impulsive Type, Ad/HD - Combined Type with Obsessive-Compulsive features, AD/HD - Combined Type with Obsessive/Compulsive and Conduct Disorder features and Undifferentiated AD/HD. However, the present study did not find evidence of subtypes that corresponded to Amen's Temporal Lobe ADD or Limbic ADD. Discriminant function analysis of the six clusters found that the variables in the model (symptom percentage scores) significantly discriminated the subtype classification. Also, 76% of all cases were correctly classified according to their symptom presentation. Potential limitations of the sample and the data used for interpretation were discussed. Limitations of the study warrant further investigation making use of multi-modal assessment tools which relate well with brain imaging techniques, such as neuropsychological measures of attention and concentration, laboratory based measures of activity, continuous performance tests measuring inattention and impulsivity, and QEEG data measuring brain wave information. A multi-modal approach to investigating symptom subtypes of AD/HD would likely provide increased reliability and validity of differential diagnosis, and therefore, more effective treatment of children with the presenting symptomology of AD/HD. The diagnostic and clinical implications' of each cluster subtype symptomology found in the present study was discussed as well.

Demographic Variables and Their Relation to Self-Concept in Children with and Without Attention-Deficit/Hyperactivity Disorder

Barton, Kimberly A. 08 1900 (has links)
The proposed study examined differences in self-concept between ADHD (n = 61) and non-ADHD boys and girls. Participants included 108 children between 6 and 11 years old. Children completed the Self Description Questionnaire-I, and teacher reports of child competence were obtained. Girls reported lower physical ability and mathematics self-concept than boys. The results also indicated that ADHD girls may be more susceptible to low physical ability and mathematics self-concept than control children or ADHD boys. Teachers also rated ADHD girls as having lower scholastic competence than the other three groups. Teachers reported significant differences in level of competence based on ADHD status. The implications of the current study and directions for future research will be presented.

Arbetsterapeuters erfarenheter av förskrivning av kognitiva hjälpmedel för vuxna med ADHD / Occupational therapists experience of prescribing cognitive assistive technology for adults with ADHD

Haslum, Charlotte, Wadin, Marika January 2017 (has links)
The aim of this study was to describe occupational therapists’ experience of prescribing cognitive assistive technology for adults with ADHD. Semi-structured interviews were conducted with eight occupational therapists who worked in a region in central Sweden. A qualitative content analysis was used to analyze the data and resulted in four categories; Interview the client regarding their daily activities to assess their needs of cognitive assistive technology, the importance of adapting strategies based on the client’s abilities, the importance of client participation and individualized routines to follow-up cognitive assistive technology. The results showed that occupational therapists used different approaches to assess the client's daily activities prior to prescribing cognitive assistive technology. An important approach was to customize strategies based on the client's prerequisites and to promote its motivation and participation. Furthermore, the result showed that prescribing cognitive assistive technology is a time-consuming process.

Predictors of Barriers to Psychosocial Treatment for African American Families of Children with ADHD

Wilson, Stephanie A 01 January 2017 (has links)
African American families of youth with Attention-deficit/hyperactivity disorder (ADHD) traditionally have lower rates of ADHD treatment compared to nonminority groups. These treatment disparities underscore the importance of better understanding the barriers to treatment for these families. Therefore, in a sample of 67 African American caregivers of children with ADHD, the current study examined (1) factors that predict barriers to treatment for African American families of children with ADHD and (2) whether caregiver impairment mediates comorbid behavior problems and barriers to treatment for African American youth with ADHD. Analyses revealed that caregiver impairment predicted barriers to treatment and mediated the relationship between comorbid behavior problems and barriers to treatment. These findings highlight how caregiver impairment may play a significant role in preventing African American families from engaging in ADHD treatment for their child. Furthermore, targeting caregiver impairment in treatment may be particularly beneficial for African American families of youth with ADHD.

Adult Attention Deficit Hyperactivity Disorder Personality Characteristics and Comorbidity

Austin, Karla Michele 08 1900 (has links)
Attention-deficit/hyperactivity disorder (ADHD) is surrounded by confusion and controversy regarding its definition, course, etiology and treatment. Among adults, ADHD is rarely considered a diagnostic reality of primary importance and is often overlooked. This study provides descriptive validity for adult ADHD in distinguishing it from controls, and identifying both a pure condition and one wrought with comorbidity.

Positive Illusory Bias in Adolescents with ADHD: Prevalence, Stability, and Accuracy of Reporters

Bourchtein, Elizaveta 01 January 2016 (has links)
The positive illusory bias (PIB) – over-reporting levels of self-competence compared to other raters – has been demonstrated in youth with attention-deficit/hyperactivity disorder (ADHD), despite increased impairment rates. However, due to inconsistent definitions of the PIB, conflicting findings have emerged regarding prevalence of the PIB in youth with ADHD and whether parent or child report is actually “biased” and driving the PIB. Additionally, stability of the PIB across time is unknown. The present study used person-centered methodology cross-sectionally and longitudinally to evaluate the prevalence of the PIB in adolescents with ADHD. Results revealed a cross-domain global PIB group at baseline (18.4% of sample) but only a small social PIB group was present and stable across time. Parents in the PIB group were better reporters of scholastic competence relative to an objective measure than were youth. These findings suggest that the PIB may be significantly less prevalent in this population than previously thought.

THE CONSEQUENCES OF ALCOHOL MIXED WITH ENERGY DRINK (AMED) USE IN COLLEGE STUDENTS WITH ATTENTION-DEFICIT/HYPERACTIVITY DISORDER (ADHD)

GREEN, BROOKE A 01 January 2016 (has links)
College students with ADHD, but especially those who consume alcohol, may be at jeopardy for experiencing negative educational and occupational outcomes, problematic substance use, criminal offending, and sexual victimization. Alcohol mixed with energy drink (AmED) use is widespread across college campuses and associated with many of these same problematic outcomes. The risk of experiencing these consequences for college students with ADHD may be exacerbated by AmED use given its unique relationship, above and beyond alcohol use, with these variables. This study sought to examine relationships among GPA, lost work performance, hazardous alcohol use, illicit substance use, criminal offending, and sexual victimization in college students with ADHD who use AmED. The sample comprised students (N = 248; 36.3% male, 63.7% female) from the University of Albany’s (UAlbany) and Virginia Commonwealth University’s (VCU) disability support centers, as well as VCU’s SONA psychology subject pool. Hierarchical linear regression analysis and logistic regression analysis were used to test six hypotheses. Results showed that AmED use did not predict GPA, lost work performance, or criminal offending. However, AmED use did predict hazardous alcohol use (p < .001), illicit substance use (p < .05), and sexual victimization (p < .05). These findings provide a baseline rate of AmED use in college students with ADHD, and highlight the importance of further research regarding the potential consequences of AmED use in this population.

Merely Misunderstood: Expressive, Receptive, and Pragmatic Language in Children with Disruptive Behavior Disorders

Gremillion, Monica L 17 December 2011 (has links)
Children with Disruptive Behavior Disorders (DBD), including Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) have poorer language skills compared to typically developing children; however, language as a potential risk factor for DBD has received little empirical attention or evaluation. Receptive, expressive, and pragmatic language skills in preschoolers with DBD were examined. Participants were 82 preschool-age children and their primary caregivers. Primary caregivers completed a semi-structured interview and symptom and language questionnaires. Preschoolers completed measures of receptive and expressive language. Results indicated that preschoolers with DBD were more impaired on receptive, expressive, and pragmatic language compared to non-DBD children. Pragmatic language appears particularly impaired in children with DBD, and language problems appear most linked with increased hyperactivity-impulsivity (vs. inattention or oppositional-defiance). This work suggests the need for early assessment of language in preschoolers with DBD, as well as the possibly utility of tailored interventions focusing on improving pragmatic language.

ADHD Symptomology and Overweight Among College Men

Johnson, Leslee M. 12 1900 (has links)
Attention deficit/hyperactivity disorder (ADHD) is a childhood disorder that often persists into adulthood. Among adults, ADHD is highly comorbid with addictive behaviors (e.g., substance abuse and dependence), and depressive disorders. Recently, an association between ADHD and obesity has been reported in the literature; emotional and binge eating may be “addictive behaviors” that contribute to weight gain in this population. The purpose of this study was to test competing models of the hypothesized link between ADHD symptomology and overweight. Specifically, in Model 1, symptoms of depression are expected to mediate the relationship between symptoms of impulsivity and inattention and emotional and binge eating which, in turn, leads to weight gain (i.e., increased BMI). In Model 2, however, the impulsive symptoms have direct relationships with emotional and binge eating in addition to being mediated by depressive symptoms. Structural equation modeling (SEM) was employed to test how the models fit the data of 790 college men. Both models fit the data well, with Model 2 being preferred because of its greater connection to theory. All paths were significant indicating that increased impulsive and inattentive symptoms predicted increased symptoms of depression that, in turn, predicted increased emotional/binge eating, which has a direct and positive relationship with increased BMI. Moreover, impulsive symptoms were also directly related to emotional/binge eating, suggesting different paths to overweight across ADHD subtypes. The findings of the current study elucidate the links between ADHD symptoms and overweight (i.e., increased BMI).
