Examination of the validity and usefulness of the video suggestibility scale for children

The Video Suggestibility Scale for Children (VSSC) was developed by Scullin and colleagues (Scullin & Ceci, 2000; Scullin & Hembrooke, 1998) as a tool for discriminating between children who have different levels of suggestibility. The scale requires children to view a 5-minute video about a birthday party, and to subsequently participate in an interview consisting of 18 yes/no questions. The VSSC consists of two main subscales; Yield (a measure of children's willingness to respond affirmatively to misleading questions about the video) and Shift (a measure of the children's tendency to change their responses after negative feedback from the interviewer). Preliminary research by Scullin and colleagues suggested that the scale possesses satisfactory internal consistency and that children's scores on the VSSC can predict their performance in another suggestibility paradigm. This thesis presents two studies, which further examine the validity and usefulness of the VSSC in an Australian sample of 3- to-5-year-old children. In Study One, children's performance on the VSSC (N = 77) was compared to their performance using other measures of suggestibility. These measures included children's willingness to assent to a false event as well as the number of false interviewer suggestions and new false details that the children provided in their accounts about an independent true-biased and an independent false (non-experienced) event. An independent samples t-test revealed that those children who assented to the false activity generated higher scores on the Yield measure. This pattern was also observed for the Shift subscale although it was not significant. Hierarchical regression analyses revealed that Yield was a significant predictor of the number of false details reported about the false activity, but not the true-biased activity. There was no significant relationship between the Shift Vlll subscale and any of the dependent variables. Overall this study provided partial support for the construct validity of the VSSC. However, it indicated that children's performance on this scale may not be generalisable across different contexts and interview paradigms, and that the Yield subscale is more generalisable than the Shift subscale. Study Two examined whether various group and individual factors that have previously been shown to relate suggestibility (i.e., age, IQ, memory, socio-economic status, gender, temperament) could predict suggestibility as measured by the VSSC. Two hundred and twenty children were recruited from kindergartens, and were divided into two broad socio-economic categories (based predominantly on income). Hierarchical regression analyses revealed that age, intelligence and memory inversely predicted children's Yield suggestibility. Further, children of low socio-economic backgrounds were more suggestible than children of high socio-economic background, and boys were more suggestible than girls on the Yield measure. Although shyness and other internalised and externalised characteristics were explored, no reliable significant relationships were found with Yield. With regard to the Shift subscale, no reliable relationships were found for any of the independent variables except for SES. Overall, results of Study 2 indicated that the VSSC is a potentially useful measure for discriminating between children's suggestibility on the basis on their individual characteristics, although benefits were observed mainly in relation to the Yield subscale. With reference to the findings of these two studies, the potential contribution of the VSSC for research and applied forensic contexts was discussed.

A cross-cultural examination of social and sexual behaviour in High Functioning Autism and Down Syndrome

The focus of this research was to obtain an understanding of the social and sexual behaviour of adolescents with High Functioning Autism (HFA) or Down Syndrome (DS) in comparison to Typically Developing (TD) adolescents across cultures. The findings highlight the importance of cross-cultural research and indicate the need for sex education. The portfolio presents four case studies which support the proposition that insecure attachment is only likely to lead to depression in the presence of socially-related and other psychological difficulties, since not all insecurely attached children develop depressive symptoms.

An examination of Australia's insider trading laws

Considers that the effective regulation of insider trading is desirable in order to maintain investor confidence in Australia's share markets. Although the current laws and the use of continuous disclosure provide a workable foundation, the thesis further considers the ways in which insider trading may be more effectively regulated and prosecuted in Australia.

Critical examination of clinical teaching in undergraduate nurse education

Reports on the complex work of Australian clinical nurse teachers, identifying the influence of a range of socio-political factors. Teachers worked from personal curricula and often developed maternal relationships with students. They used time to descipline student learning whilst simultaneously being desciplined in their teaching practices by time.

An examination of financial counselling discourses in Victoria

This thesis investigates the model of practice invoked by the Victorian financial counselling sector. It analyses why community development is inconsistent with the sector's casework approaches to practice, identifies the emergence of a different model of practice and explains financial counselling within the current theoretical context of risk society.

An examination of the consistency of investigative interviewers' performance

Three original studies were conducted to examine the consistency of investigative-interviewer performance across similar and distinct interview tasks. Overall, the degree of consistency depended on numerous factors, including the nature of the event and interview paradigm, the precision of the assessment measure and whether group versus individual stability was measured. The portfolio highlights and discusses some of the complexities that can arise when conducting a parenting capacity assessment with a patient who has, or is suspected of having, an intellectual disability. Four case studies are presented.

Human factors in cargo X-ray examination systems

The project investigated factors which may determine operator performance in X-ray screening of cargo, which is of similar importance to aviation security screening. A target detection paradigm showed significant difference in several measures of performance between baggage and postal contexts which provides evidence that these may constitute separate expertise domains.

An examination of adolescents' help seeking processes

This thesis examined factors that predict adolescents' professional help seeking when experiencing mental health problems over six months. Factors that strongly predicted help seeking included adolescents' ability to recognise that they were experiencing a problem; the type and severity of the problem experienced; and the preceived support from their family. The portfolio examined the potential benefits of using manualised CBT programs in a more flexible and individualised manner when treating children and adolescents.

Internet child pornography : an examination of attachment and intimacy deficits

This study found that Internet child pornographers (ICP) reported significantly less optimal attachment than non-offenders, matched child and matched adult sexual offenders. ICP also reported a more negative view of self than non-offenders and the matched sexual offender groups. Finally, the ICP group reported more social avoidance and distress than non-offenders. The portfolio explores the influence of treatment readiness on the best practice principles when working with violent offenders in relation to their assessment, and subsequent treatment recommendations. The importance of treatment readiness and its utility in relation to these principles is highlighted in four case studies.

Wool industry : a decade of turbulence : an examination of some of the factors contributing to the crisis within Australia's wool industry, and the resulting economic, social and demographic effects on a small isolated rural community

A central issue of this thesis has been an examination of the effects that the current wool crisis has had on the Balmoral district, an area almost solely devoted to the production of wool and wool sheep. Examines the methods being utilised to try to alleviate some of these effects.

An examination of the range of self-funding options available to regional galleries and an assessment of their suitability for use in those institutions

Researches the suitability of a variety of self-funding options available to regional galleries in Australia. An overview of the range of current self-funding practices is given. Each option is mapped according to its impact on core/value added services and its effect on primary/secondary users and assessed for suitability using these criteria.
