Investigative interviewers' perceptions of the value of different training Tasks on their adherence to open-ended questions with children

Prior research has highlighted the considerable difficulties investigative interviewers have in adhering to open-ended questions in child abuse interviews. Although improvements in interviewing can be achieved by providing training that incorporates multiple practice opportunities and feedback, currently little is known about the way in which these elements are best administered. The current study extends debate and research on this issue by examining the perceptions of 15 trainee interviewers (police as well as social workers) regarding the relative value of various practical training exercises experienced in a recent training program. The findings indicated that although practice in interviewing was deemed essential, not all tasks were perceived to be equally beneficial. The two most favoured exercises were (a) simulated interviews involving trained actors playing the role of the child, and (b) self-evaluation of a transcribed interview using an objective coding protocol. A summary of the participants' perceptions is provided along with a discussion of the implications for trainers and researchers.

Improving the competency of police officers in conducting investigative interviews with children

Despite the provision of 'best-practice' guidelines regarding conducting interviews with children, research indicates that most investigative interviews do not adhere to these guidelines. To date, there has been little discussion in the literature of the conditions that are needed to promote and sustain expertise in forensic interviewing. The current paper addresses this limitation by describing the main factors preventing the adoption of 'best-practice' interview guidelines. A description of these barriers (and the literature that supports them) forms the basis for the review component of this paper as well as the subsequent recommendations for change.

Sociodemographic and behavioural correlates of weight status among women with children living in socioeconomically disadvantaged neighbourhoods

Objective: To investigate sociodemographic and behavioural characteristics associated with weight status among women with children living in socioeconomically disadvantaged neighbourhoods.
Methods and procedures: A total of 1680 women aged 18–46 years, living in socioeconomically disadvantaged neighbourhoods with dependent children (aged 0–18 years), provided self-report data on height and weight and a range of sociodemographic and behavioural (for example, dietary intake, physical activity and time spent sitting) characteristics.
Results: Half of the women were classified as having a healthy weight (body mass index=18.5–25). Bivariable ordinal logistic regression analyses indicated that a healthy weight status was associated with a range of sociodemographic and behavioural characteristics. In a multivariable model, a healthy weight status among women was associated with being younger and unmarried, speaking a language other than English at home, having a medium or high level of education, and a partner with a high level of education, having a high household income, spending more time engaged in leisure-time physical activity and less time spent sitting, and having a lower consumption of soft drink.
Discussion: The present findings highlight that a considerable proportion of women with children living in disadvantaged neighbourhoods manage to maintain a healthy weight. Acknowledging the cross-sectional nature of this study, strategies aimed at helping women with children in socioeconomically disadvantaged areas to maintain their weight should focus on increasing physical activity, and reducing sitting time and soft drink consumption.

Variables associated with children's physical activity levels during recess : the A-CLASS project

Background
School recess provides a daily opportunity for children to engage in physically active behaviours. However, few studies have investigated what factors may influence children's physical activity levels in this context. Such information may be important in the development and implementation of recess interventions. The aim of this study was to investigate the association between a range of recess variables and children's sedentary, moderate and vigorous physical activity in this context.

Methods
One hundred and twenty-eight children (39% boys) aged 9-10 years old from 8 elementary schools had their physical activity levels observed during school recess using the System for Observing Children's Activity and Relationships during Play (SOCARP). Playground variables data were also collected at this time. Multilevel prediction models identified variables that were significantly associated with children's sedentary, moderate and vigorous physical activity during recess.

Results
Girls engaged in 13.8% more sedentary activity and 8.2% less vigorous activity than boys during recess. Children with no equipment provision during recess engaged in more sedentary activity and less moderate activity than children provided with equipment. In addition, as play space per child increased, sedentary activity decreased and vigorous activity increased. Temperature was a significant negatively associated with vigorous activity.

Conclusions
Modifiable and unmodifiable factors were associated with children's sedentary, moderate and vigorous physical activity during recess. Providing portable equipment and specifying areas for activities that dominate the elementary school playground during recess may be two approaches to increase recess physical activity levels, though further research is needed to evaluate the short and long-term impact of such strategies.

Maternal self-efficacy regarding children's eating and sedentary behaviours in the early years : Associations with children's food intake and sedentary behaviours

Introduction. This cross-sectional study aimed to describe parents' views regarding self-efficacy to influence children's eating and sedentary behaviours at two time points in early childhood, and to examine associations between these views and children's eating and sedentary behaviours.

Methods. Mothers of 1-year (n=60) and 5-year-old children (n=80) were recruited through Maternal and Child Health Centres and kindergartens in Victoria, Australia. Mothers reported children's dietary intake, television viewing and perceptions of their self-efficacy regarding children's eating and sedentary behaviours.

Results. Overall, 5-year-old children consumed significantly more energy-dense food and drink and spent significantly more time viewing TV/DVD and video. Mothers of 1-year-olds were significantly more likely to report they felt confident to limit child's consumption of non-core foods/drinks, and to limit screen access (p<0.001). Measures of maternal self-efficacy were directly associated with 5-year-old children's water (p<0.05), and fruit and vegetable consumption (p<0.005), and with 1-year-old children's vegetable consumption (p<0.05), and were inversely associated with cordial and cake consumption (p<0.05). Maternal self-efficacy to limit viewing time was inversely associated with screen-time exposure in both age groups (p<0.01).

Conclusion. This study suggests that mother's self-efficacy regarding limiting non-core foods/drinks and limiting screen-time exposures may decline during the first few years of a child's life. Higher maternal self-efficacy was associated with children having more obesity protective eating and sedentary behaviours at both ages. Interventions to support the development of healthy lifestyle behaviours may be most effective if they target mothers' self-efficacy in these domains early in their child's life.

A systematic review of the validity and reliability of sedentary behaviour measures used with children and adolescents

The aim of this review was to evaluate the reliability and validity of methods used to assess the multiple components of sedentary behaviour (i.e. screen time, sitting, not moving and existing at low energy expenditure) in children and adolescents. Twenty-six studies met our inclusion criteria and were reviewed. Thirteen studies reported the reliability of self- and proxy-report measures of sedentary behaviour and seven of these were found to have acceptable test–retest reliability. Evidence for the criterion validity of self- and proxy-report measures was examined in three studies with mixed results. Seven studies examined the reliability and/or validity of direct observation and the findings were generally positive. Five studies demonstrated the utility of accelerometers to accurately classify sedentary behaviour. Self-report measures provide reliable estimates of screen time, yet their validity remains largely untested. While accelerometers can accurately classify participants’ behaviour as sedentary, they do not provide information about type of sedentary behaviour or context. Studies utilizing measures of sedentary behaviour need to more adequately report on the validity and reliability of the measures used.We recommend the use of objective measures of sedentary behaviour such as accelerometers, in conjunction with subjective measures (e.g. self-report), to assess type and context of behaviour.

Two novel missense mutations in hairy-and-enhancer-of-split-7 in a family with spondylocostal dysostosis

Spondylocostal dysostosis (SCD) is an inherited disorder with abnormal vertebral segmentation that results in extensive hemivertebrae, truncal shortening and abnormally aligned ribs. It arises during embryonic development by a disruption of formation of somites (the precursor tissue of the vertebrae, ribs and associated tendons and muscles). Four genes causing a subset of autosomal recessive forms of this disease have been identified: DLL3 (SCDO1: MIM 277300), MESP2 (SCDO2: MIM 608681), LFNG (SCDO3: MIM609813) and HES7 (SCDO4). These genes are all essential components of the Notch signalling pathway, which has multiple roles in development and disease. Previously, only a single SCD-causative missense mutation was described in HES7. In this study, we have identified two new missense mutations in the HES7 gene in a single family, with only individuals carrying both mutant alleles being affected by SCD. In vitro functional analysis revealed that one of the mutant HES7 proteins was unable to repress gene expression by DNA binding or protein heterodimerization.

The reliability of two visual motor integration tests used with children

Occupational therapists often assess the visual motor integration (VMI) skills of children and young people. It is important that therapists use tools with strong psychometric properties. This study aims to examine the reliability of 2 VMI tests. Ninety-two children between the ages of 5 and 17 years (response rate of 31%) completed 2 VMI tests: the Developmental Test of Visual Motor Integration (DTVMI) and the Full Range Test of Visual Motor Integration (FRTVMI). Cronbach's alpha coefficient was used to examine the internal consistency of the 2 VMI tests whereas Spearman's rho correlation was used to evaluate the test–retest reliability, intrarater reliability, and interrater reliability of the 2 VMI tests. The Cronbach's alpha coefficient for the DTVMI was .82 and .72 for the FRTVMI. The test–retest reliability coefficient was .73 (p = .000) for the DTVMI and .49 (p = .05) for the FRTVMI. The interrater correlation was significant for both the DTVMI at .94 (p = .000) and FRTVMI at .68 (p = .001). The DTVMI intrarater reliability correlation result was .90 (p = .000) and the FRTVMI at .85 (p = .000). Overall, the DTVMI exhibited a higher level of reliability than the FRTVMI. Both VMI tests appear to exhibit reasonable levels of reliability and are recommended for use with children and young people.
