The development of the nutrition and activity knowledge scale for use with people with an intellectual disability

Background Obesity is an increasing health problem for many Australians, no less so among people with an intellectual disability. Behaviour change aimed at improving nutritional intake and increasing levels of physical activity is a requirement for the reduction of obesity. An essential part of this process is to first ascertain the level of knowledge and beliefs people with an intellectual disability have about these behaviours.

Methods The aim of this study was to develop and psychometrically evaluate a scale to assess levels of nutritional and physical activity knowledge among people with an intellectual disability.

Results Seventy-three people with an intellectual disability completed the interview-rated scale at time 1 and 66 of them completed it again at a 3-week re-test.

Conclusions The scale demonstrated strong factorial construct validity, high internal consistency and good temporal stability. The applications of this scale in future research and in intervention programmes are discussed.

Pharmacological management of challenging behavior of individuals with intellectual disability

In many Westernized countries, including Australia, concerns about the use of psychotropic drugs to manage the challenging behavior of individuals with intellectual disability have resulted in the development of legislative and procedural controls. Although these constraints may limit indiscriminate use, employing medication remains a common practice. This study examined information about 873 individuals (566 males, 307 females) who were the subjects of reports to the Intellectual Disability Review Panel in March 2000 concerning the use of chemical restraint. A high proportion of people with intellectual disability were reported to have received drugs for purposes of behavioral restraint. The range of drugs was extensive, although those from the antipsychotic class were the most frequently reported. Many individuals concurrently received more than one type of drug or more than one drug from the same drug class. More males than females and more older than younger individuals were administered medication. A relationship between gender and age was apparent, with younger males but older females dominating. The use of drugs to mange the behavior of people with intellectual disability may at times be warranted. However, it is important that the extent and type of drug use, as well as the characteristics of those who are medicated, be subject to ongoing scrutiny.

An investigation into the incidence of obesity and underweight among adults with an intellectual disability in an Australian sample

Reports suggest that 7% to 18% of Australian adults are obese and a further 16% to 55% are overweight. Studies from other countries have indicated that obesity among people with an intellectual disability may be at least, or even more, prevalent. Prevalence rates range from 28% to 59%. The aim of the current study was to investigate the weight distribution of an Australian sample of people with an intellectual disability using Body Mass Index (BMI) to classify males and females, and Kelly and Rimmer's (1987) Percentage of Body Fat (PBF) formula to also classify males. Forty-one females and 52 males with a mild to severe intellectual disability were assessed. The correlation between BMI and PBF for males was r=.89. BMI classifications revealed a higher percentage of females as overweight (41.4%) and obese (36.6%) compared to overweight males (30.8%) and obese males (30.8%). There were more underweight males (7.6%) than females (4.9%). There was no relationship between living environment and weight classifications on the BMI. The PBF formula indicated that 73% of the males were classified as obese. The possibility of misclassification using the BMI and the need for weight interventions are discussed.

The effect of intellectual disability on children's recall of an event across different question types

This research examined the performance of 80 children aged 9–12 years with either a mild and moderate intellectual disability when recalling an innocuous event that was staged in their school. The children actively participated in a 30-min magic show, which included 21 specific target items. The first interview (held 3 days after the magic show) provided false and true biasing information about these 21 items. The second interview (held the following day) was designed to elicit the children's recall of the target details using the least number of specific prompts possible. The children's performance was compared with that of 2 control groups; a group of mainstream children matched for mental age and a group of mainstream children matched for chronological age. Overall, this study showed that children with either a mild or moderate intellectual disability can provide accurate and highly specific event-related information. However, their recall is less complete and less clear in response to free-narrative prompts and less accurate in response to specific questions when compared to both the mainstream age-matched groups. The implications of the findings for legal professionals and researchers are discussed.

Police perceptions of interviews involving children with intellectual disabilities: a qualitative inquiry

This study employed a qualitative method to explore the experiences of 20 police officers when interviewing children with intellectual disabilities. Three main themes were interpreted as representing challenges to the officers when interviewing special-needs children: police organizational culture, participants' perceptions of these children as interviewees, and prior information. Participants in this inquiry mentioned poor organizational priority within the police force for child abuse cases and children with intellectual disabilities, as well as inadequate support for interviewing skills development and maintenance. Participants also attempted to equalize these children by interviewing them in the same way as their mainstream peers. Finally, participants viewed interview preparation as influential in determining an interview's successful outcome, but recognized that preparedness could bias their interviewing techniques. Increased attention towards these issues will provide a basis for developing strategies to minimize such challenges and thus improve the quality of interviews with children with intellectual disabilities.

What is 'political communication'? The rationale and scope of the implied freedom of political communication

The aim of this article is to identify what counts as ‘political communication’ for the purposes of the implied constitutional freedom of political communication. This is done for two reasons. The first is to delimit the scope of the implied freedom. The second is to clarify whether racial vilification is ‘political communication’, which is the initial step that must be taken in order to assess the constitutionality or otherwise of current Australian racial vilification laws. It is, however, necessary and desirable to establish a sound theoretical basis for the implied freedom before these questions can be properly considered. To this end, it is argued that a minimalist model of judicially-protected popular sovereignty underpins the implied freedom and is the rationale that must guide its interpretation and application. The analysis undertaken demonstrates that a generous zone of ‘political communication’ must attract constitutional protection and that racial vilification will in certain circumstances amount to ‘political communication’.

Publication bias in the economic freedom and economic growth literature

The impact of institutions on economic performance has attracted significant attention from researchers, as well as from policy reformers. A rapidly growing area in this literature is the impact of economic freedom on economic growth. The aim of this paper was to explore publication bias in this literature by means of traditional funnel plots, meta‐significance testing, as well as by bootstrapping these meta‐significance tests. When all the available estimates are combined and averaged, there seems to be evidence of a genuine and positive economic freedom – economic growth effect. However, it is also shown that the economic freedom – economic growth literature is tainted strongly with publication bias. The existence of publication bias makes it difficult to identify the magnitude of the genuine effect of economic freedom on economic growth. The paper explores the differences between aggregate and disaggregate measures of economic freedom and shows that selection effects are stronger when aggregate measures are used.

Bad, mad and sad : developing a methodology of inclusion and a pedagogy for researching students with intellectual disabilities

A critical question for me as a teacher/researcher in the field of inclusive education is how to reposition children with moderate and severe intellectual disabilities as participants rather than subjects in the debate. In this paper, I develop a methodology of inclusion that comprises an ethics of consent and a pedagogy for research participation that is an opportunity not only to teach, but also to create a new discursive space for six children to speak. The discussion explores a range of methodological and interpretive strategies for including children with significant intellectual disabilities in research: issues of informed consent, the negotiation of power relations and the ways in which this innovative pedagogy can be empowering beyond the research situation. The use of this methodology has provocative implications concerning what might be learned about forging a link between the struggle for change and educational policy/practice if other researchers worked towards creating spaces for these most marginalized children to speak.

The relationship between residence and the pharmacological management of challenging behavior in individuals with intellectual disability

Many individuals with intellectual disability are administered psychotropic drugs to manage their challenging behavior. The increased relocation of individuals from institutions into community-based accommodation during the past decade provides an opportunity to examine the relationship between setting and drug administration. This study provides acomparison of drug use according to the type of residential facility of 873 individuals reported to have been administered drugs for behavioral restraint in March 2000, with 762 individuals reported in March 1993. In 2000, individuals in institutions were reported toreceive a moderately greater number of drugs concurrently than those in the community. However, there were no differences in the proportion of individuals prescribed drugs relative to the total population living in the respective settings. This is in contrast to the findings from 1993, where drug use was greater in individuals who were living in institutions. It was also more common for individuals who continued to be medicated across time to have previously lived in an institution. Although relocation into the community may be associated with improved living conditions, it is important to recognize that this change in living conditions is not necessarily associated with less use of drugs to manage behavior.

Economic freedom and economic growth: Does specification make a difference?

In this paper we apply meta-analytic techniques to the literature on the impact of economic freedom on economic growth and find an overall positive direct association between economic freedom and economic growth. A positive indirect effect of economic freedom on economic growth through the stimulation of physical capital is also identified. However, the literature is affected by specification bias with respect to controls for physical capital. The omission of physical capital results in larger estimates of the economic freedom–economic growth association. Further, the use of panel data leads to smaller estimates of the impact of economic freedom on economic growth. The meta-analysis is confirmed by primary cross-sectional and panel data analysis of 82 countries for the period 1970–1999.

Emerging trends in the use of drugs to manage the challenging behaviour of people with intellectual disability

Background Concerns about the pharmacological management of the behaviour of individuals with intellectual disability have resulted in the development of legislative and procedural controls.
Method This Australian study provided a comparison of 873 reported cases where drugs were administered to manage behaviour in March 2000, with 762 cases reported in March 1993. Drug use in individuals who remained medicated across time (n = 316: recurrent sample) was also compared with those who were reported only in 1993 (n = 329: limited sample).
Results A small decrease in the proportion of individuals who were reported to have received medication was evident over time (from 5% to 4.5% of total population). However, this was accompanied by an increase in drug diversity and interclass polypharmacy. An increase in antidepressant use was evident (from 7.4% to 13.8% of reported drugs), and there was a trend towards greater reporting of medication for acute behavioural problems and medication use with children. Greater use of antipsychotic drugs was evident in individuals who remained medicated across time compared with those who did not.
Conclusions The findings suggest the need for continuous research into practice. The fact that many individuals receive medication over long periods makes it incumbent on service providers to engage in regular, comprehensive and individualized review and evaluation of medication regimes.

Effectiveness of treatment programmes for depression among adults with mild/moderate intellectual disability

Background The current study describes the development and evaluation of group treatment programme for people with mild/moderate intellectual disability (ID).
Methods A total of 34 participants (16 males, 18 females) completed the treatment programme and 15 participants (six males, nine females) comprised a control group.
Results Compared to the control group, the intervention group showed an improvement in levels of depression, positive feelings about the self, and lower levels of automatic negative thoughts after the intervention. These changes were maintained at 3-month follow-up.
Conclusions These results demonstrate that intervention programmes are effective for the treatment of depression among people with ID.

Sex offenders in a risk society : setting limits on freedom

The commendable intention to protect children from risk must be weighed against loss of personal freedom when imposing extended supervision orders under the Serious Sex Offenders Monitoring Act.
