Autistic symptoms appear to change during adolescence. This study replicates an earlier one (McCallon, 1985) which attempted to validate the use of the Childhood Autism Rating Scale (CARS) with adolescents. The standard observation method of administration was used. Additionally, information obtained in structured parent interviews was used to score a CARS. Subjects were nine autistic and nine nonautistic retarded adolescents from 13 to 21 years of age. Results suggested that the CARS, administered either way, validity discriminates between retarded adolescents who are diagnosed as autistic and those with other handicaps. Methodological limitations of the present study are discussed.

Autism or autism spectrum disorder (ASD) is a multifaceted neurological condition that impairs social interaction, communication and behaviour. The current increase in the prevalence of ASD is alarming. A large population of parents is left searching for answers regarding their child’s developmental delays. Once their child has been diagnosed, they have to deal with the challenge of raising such a child. Parenting a child with ASD is particularly challenging for mothers as it has been reported that they struggle with poor health and wellbeing as well as high stress levels. Literature has also shown that the maternal interaction style impacts the prognosis for the child’s development, again highlighting the importance of the mother’s wellbeing. Several studies refer to the severe impact of ASD on the family as a unit, yet the unique challenges that mothers face are often overlooked. To address the wellbeing of these mothers, it is necessary to understand their experiences of their child’s diagnosis with ASD. This qualitative phenomenological study explored and described mothers’ experiences of their child’s diagnosis with ASD by using the Process-Person-Context-Time model from Bronfenbrenner’s bioecological theory as a framework. Unstructured interviews with seven mothers were conducted, voice recorded and transcribed. Data was analysed using thematic content analysis. Findings revealed four interrelated themes: 1) the mother’s experience of the interactions and relationships within her immediate family (Proximal Process), 2) the mother’s experience of her internal and external characteristics and resources (Person), 3) the mother’s experience of her environment (Context), and 4) the mother’s experience of the journey through time (Time). Bronfenbrenner’s theory in its matured form also proved to be of value in understanding these mothers’ daily lives and challenges. The key findings provide valuable insight that may inform professionals who develop support programmes aimed at mothers with ASD children or that may guide such professionals’ therapeutic interventions with mothers with ASD children. / MSW, North-West University, Potchefstroom Campus, 2015

It is now known that autism is a lifelong handicapping condition. While some of the characteristic behaviors of autistic children remain unchanged in adolescence and adulthood, there is evidence that other behaviors change as a function of development. Assessment instruments for identifying autism are generally intended for use with. young children and may not accurately assess autism in adolescents. Two studies compared autistic adolescents with matched autistic children and nonautistic adolescents on two autism rating scales. The validity of the Childhood Autism Rating Scale for use with adolescents was supported while the validity of the Prescreening Checklist was questioned. The findings were discussed in relation to the age-related changes which occur in autistic adolescents.

The diagnosis of autism is a comprehensive process that requires trained professionals and is often a time consuming process. Behavior rating scales are common components used by practitioners in evaluations to assess various social, emotional, or behavioral problems. With the rise of awareness, the steady increase of autism diagnoses, and the importance of early identification to increase the effectiveness of intervention, there is a need for screeners to identify the characteristics of Autism Spectrum Disorders. The purpose of the present study was to determine if there was a group of items on the Child Behavior Checklist/1.5-5 that reliably distinguished between children with autism and referred, but non-spectrum children. A behavior rating scale was completed by parents and/or guardians of 156 preschool children with autism and without autism. Analyses of the data revealed a grouping of items that were significantly correlated with the diagnosis of autism. Based on predetermined cutoff scores, sensitivity, and specificity; the group of items may be useful in the recommendation of further assessment of autism.

Parent-child social games, such as peek-a-boo and patty-cake, are a key element of an infant's earliest social interactions. The analysis of children's behaviors in social games based on video recordings provides a means for psychologists to study their social and cognitive development. However, the current practice in the use of video for behavioral research is extremely labor-intensive, involving many hours spent extracting and coding relevant video clips from a large corpus. From the standpoint of computer vision, such real-world video collections pose significant challenges in the automatic analysis of behavior, such as cluttered backgrounds, the effect of varying camera angles, clothing, subject appearance and lighting. These observations motivate my thesis work - automatic retrieval of social games from unstructured videos. The goal of this work is both to help accelerate the research progress in behavioral science and to take the initial steps towards the analysis of natural human interactions in natural settings. Social games are characterized by repetitions of turn-taking interactions between the parent and the child, with variations that are recognizable by both of them. I developed a computational model for social games that exploits the temporal structure over a long time-scale window as quasi-periodic patterns in a time series. I presented an unsupervised algorithm that mines the quasi-periodic patterns from videos. The algorithm consists of two functional modules: converting image sequences into discrete symbolic sequences and mining quasi-periodic patterns from the symbolic sequences. When this technique is applied to video of social games, the extracted quasi-periodic patterns often correspond to meaningful stages of the games. The retrieval performance on unstructured, lab-recorded videos and real-world family movies is promising. Building on this work, I developed a new feature extraction algorithm for social game categorization. Given a quasi-periodic pattern representation, my method automatically selects the most relevant space-time interest points to construct the feature representation. Our experiments demonstrate very promising classification performance on social games collected from YouTube. In addition, the method can also be used to categorize TV videos of sports rallies, demonstrating the generality of this approach. In order to support and encourage more research on human behavior analysis in realistic contexts, a video database of realistic child play in natural settings has been collected and is published on our project website (http://www.cc.gatech.edu/cpl/projects/socialgames), along with annotations. The unsupervised quasi-periodic pattern mining method represents a substantial generalization of conventional periodic motion analysis. Its generality is evaluated by retrieving motions of a range of quasi-periodicity from unstructured videos. The performance was compared with that of a periodic motion detection method based on motion self-similarity. Our method demonstrates superior retrieval performance with a 100% precision when the recall is up to 92.04%, with much fewer parameters than that of the other method.

M.A. (Counselling Psychology) / Mothers’ experiences of raising a child who has been diagnosed with autistic disorder or autism spectrum disorder are multifaceted and multidimensional. These experiences include both negative and positive aspects which at times occur simultaneously. The aim of this research was to explore three mothers’ lived experiences of raising a child who has been diagnosed with autistic disorder. This entailed their experiences prior to receiving a diagnosis of autistic disorder for their child to their present circumstances. A hermeneutic epistemological framework, which falls in the qualitative research approach, was used. Data were collected in the form of three written narratives and three interviews which were analysed using a hermeneutic epistemological framework and thematic analysis. The analysis of the data resulted in the identification of five metathemes: the journey towards a label, challenges, attempting to be a good enough mother, coping, and personal growth. The most prominent metatheme is the three mothers’ attempts to be a good enough mother to their child with autistic disorder. Furthermore, the metathemes seem to confirm that mothers’ experiences are multidimensional and multifaceted.

MPH / Department of Public Health / Autism spectrum disorder (ASD) is a life-long neurodevelopmental disorder, which does not affect the child only but the caregiver more. ASD characterized by impairments in social interactions, communication and repetitive behaviour. Therefore, caring for a child diagnosed with ASD can be a very challenging experience for caregiver especially when knowledge about the condition is limited. The aim of the study was to explore experiences of caregivers for children diagnosed with ASD in the Ehlanzeni District, Mpumalanga Province. The study adopted a qualitative approach, wherein data was collected using face-to-face semi-structured interviews, in which an interview guide was used. Participants were selected purposively from the three different schools and data was analysed using thematic content analysis. Twelve (12) participants were interviewed for the study. The caregivers’ children were aged 5-12 years. Ethical considerations and measures to ensure trustworthiness were adhered to throughout the study. The study findings indicated that caregivers for children diagnosed with ASD experienced psychological stress, social isolation and stigma, financial burden, lack of family support, services for children with ASD were perceived not to be accessible and available. The findings also indicated that there is limited knowledge of ASD amongst caregivers, health professionals and the community at large. Therefore, more awareness campaigns need to be done on ASD to increase knowledge on the condition. Furthermore, the study recommends that support groups for caregivers of children diagnosed with ASD should be formed and that information regarding a range of inexpensive interventions and educational programs should be made available for caregivers and their children, as well as continuous dissemination of information amongst caregivers. However, limited statistical information on ASD is available on the South African context. / NRF
