Attention-Deficit/Hyperactivity Disorder (ADHD) is comorbid with a range of other disorders in clinical and community samples, including anxiety disorders. The outcomes of the Multimodal Treatment Studies of ADHD (MTA Cooperative Group, 1999) highlight the importance of this comorbidity, as children with anxiety responded differently to treatments than did children with ADHD only. At present there are few tested theoretical explanations of the etiological processes and developmental trajectories associated with their co-occurrence. The aim of this research was to put forward and examine different explanations for the comorbidity of these two disorders in children according to the framework provided by Lilienfeld (2003). This was achieved by examining the covariation of ADHD symptoms and anxiety symptoms in a community sample of 499 children aged 8-13. Dimensional assessments of psychopathology were conducted via self-report questionnaires given to children, parents and teachers. The results were analysed via structural equation modelling approaches using AMOS (Arbuckle, 2003). Consistent with the hypotheses, positive associations at Time 1 between ADHD and anxiety symptoms were linked with inattention symptoms and were particularly pronounced for girls. The concurrent positive associations observed at each time period could not be completely accounted for by overlapping symptoms across measures or by method covariance explanations. The link between ADHD and anxiety symptoms could be explained by a common factor in reporting whereby ADHD and anxiety symptoms were both associated with noncompliance and negative affect for parents' reports, and negative affect for children???s' reports. Despite the concurrent associations, there was no support for the hypothesis that ADHD symptoms predicted the development of anxiety symptoms over time, nor the alternative hypothesis that anxiety symptoms predicted the development of ADHD symptoms over time, when the stability of symptoms across time was taken into account. It was concluded that ADHD symptoms (particularly inattention) and anxiety symptoms are covarying phenomena that are linked with common features of an irritable temperament and disruptive behaviour. Future research should investigate the role of these common factors in treatment outcome and cognitive research, which has previously found differences between ADHD children with and without anxiety.

Peer victimization is a serious national concern affecting as many as 54% of typically developing children and adolescents. Although an extensive body of literature on peer victimization in typically developing youth exists, few studies have focused on how this problem affects youth with autism spectrum disorders (ASD) who may be at a higher risk to experience peer victimization due to ASD symptomology and other common comorbid characteristics (e.g., anxiety and depressive symptoms) that may invite peer aggression. In this study, 81 school-aged youth between the ages of 9 and 17 years (M= 11.91, SD= 2.32) who were diagnosed with ASD and had a full scale intelligence quotient (IQ) equal to or greater than 70 (M= 104.10, SD= 14.24) and their parents completed questionnaires examining the frequency of peer victimization and clinical characteristics of the youth. Parents (n= 81) and their children (n= 78) reported that peer victimization occurred on average a few times in the past year, and frequency did not significantly differ across gender. Parent and child reports of victimization had a significant positive relationship with child’s report of loneliness (r(78)= .46, p< .001; r(78)= .61, p< .001, respectively), anxiety and depressive symptoms (r(78)= .22, p< 0.05; r(78)= .61, p< .001, respectively), and a significant negative relationship with social skills (r(78)= -.38, p= .001; r(78)= -.30, p< .01, respectively). The relationship between child’s and parent’s report of peer victimization and child’s anxiety/depressive symptoms (b= -.01, SE= .01, p= .55; b= .01, SE= .01, p= .34, respectively) and loneliness (b= .001, SE= .01, p= .88; b= .01, SE= .01, p= .48, respectively) did not significantly vary as a function of the overall amount of social support received. Parent and child report of peer victimization did not significantly predict parent reported parental stress above and beyond ASD symptom severity (p= .37, R2 change= .01 and p= .09, R2 change= .03, respectively). Lastly, the relationship between the child’s and parent’s report of peer victimization and parent reported social avoidance was not mediated by a fear of negative evaluation. The results indicate significant predictors of peer victimizations that may assist school staff, parents and healthcare providers identify youth with ASD who may be at risk for peer victimization and may help to shape treatment protocols by targeting the associated factors of peer victimization (e.g., anxiety and depressive symptoms, social skill deficits).

Thesis (M.A.(Clinical Psychology)) -- University of Limpopo, 2012 / The aim of the study was to explore the notions of childhood mental illness by Sepedi-speaking elderly people in the Mankweng community of Limpopo Province (South Africa). Using the phenomenological method, the researcher sought to understand these elderly people’s notions with a view to: i) describing their conceptualizations of childhood mental illness; ii) determining their notions of the types and causes of mental illness; and iii) describing their views regarding the management of childhood mental illnesses. A total of 8 participants who were selected through snowball sampling were interviewed using unstructured interviews. The results of this study suggest that; i) childhood mental illness is better understood if described than defined, ii) childhood mental illness is manifested through behavioural and physical features, iii) there are many causal factors attributed to childhood mental illness, and iv) both Western and African traditional methods are recognized in the treatment of childhood mental illness in this rural community. The results are discussed in the context of the psychological literature on multicultural counseling and psychotherapy. / Department of Health and Social Development
