Expanding the concept of parental control : a role for overt and covert control in children’s snacking behaviour?

The existing literature on parental control and children’s diets is confusing. The present paper reports two studies to explore an expanded conceptualisation of parental control with a focus on overt control which ‘can be detected by the child’ and covert control which ‘cannot be detected by the child’. In study 1, 297 parents of children aged between 4 and 11 completed a measure of overt control and covert control alongside ratings of their child’s snacking behaviour as a means to assess who uses either overt or covert control and how these aspects of parental control relate to a child’s snacking behaviour. The results showed that lighter parents and those with children perceived as heavier were more likely to use covert control and those from a higher social class were more likely to use overt control. Further, whilst greater covert control predicted a decreased intake of unhealthy snacks, greater overt control predicted an increased intake of healthy snacks. In study 2, 61 parents completed the same measure of overt and covert control alongside the three control subscales of the Child Feeding Questionnaire [Birch, L.L., Fisher, J.O., Grimm-Thomas, Markey, C.N., Sawyer, R. (2001). Confirmatory factor analysis of the Child Feeding Questionnaire: A measure of parental attitudes, beliefs and practices about child feeding and obesity proneness. Appetite, 36, 201–210] to assess degrees of overlap between these measures. The results showed that although these five measures of control were all positively correlated, the correlations between the new and existing measures indicated a maximum of 21% shared variance suggesting that covert and overt control are conceptually and statistically separate from existing measures of control. To conclude, overt and covert control may be a useful expansion of existing ways to measure and conceptualise parental control. Further, these constructs may differentially relate to snacking behaviour which may help to explain some of the confusion in the literature.

Parental exercise is associated with Australian children's extracurricular sports participation and cardiorespiratory fitness : a cross-sectional study

Background: The relationship between parental physical activity and children's physical activity and cardiorespiratory fitness has not been well studied in the Australian context. Given the increasing focus on physical activity and childhood obesity, it is important to understand correlates of children's physical activity. This study aimed to investigate whether parental exercise was associated with children's extracurricular sports participation and cardiorespiratory fitness.

Methods: The data were drawn from a nationally representative sample (n = 8,484) of 7–15 year old Australian schoolchildren, surveyed as part of the Australian Schools Health and Fitness Survey in 1985. A subset of 5,929 children aged 9–15 years reported their participation in extracurricular
sports and their parents' exercise. Cardiorespiratory fitness was measured using the 1.6 km (1- mile) run/walk and inaddition for children aged 9, 12 or 15 years, using a physical work capacity test (PWC170).

Results: While the magnitude of the differences were small, parental exercise was positively associated with children's extracurricular sports participation (p < 0.001), 1.6 km run/walk time (p < 0.001) and, in girls only, PWC170 (p = 0.013). In most instances, when only one parent was active, the sex of that parent was not an independent predictor of the child's extracurricular sports participation and cardiorespiratory fitness.

Conclusion: Parental exercise may influence their children's participation in extracurricular sports and their cardiorespiratory fitness levels. Understanding the correlates of children's extracurricular sport participation is important for the targeting of health promotion and public health interventions, and may influence children's future health status.

Getting the complete picture : combining parental and child data to identify the barriers to social inclusion for children living in low socio-economic areas

Background: Childhood mental health problems are prevalent in Australian children (14–20%). Social exclusion is a risk factor for mental health problems, whereas being socially included can have protective effects. This study aims to identify the barriers to social inclusion for children aged 9–12 years living in low socio-economic status (SES) areas, using both child-report and parent-report interviews.

Methods: Australian-born English-speaking parents and children aged 9–12 years were sampled from a low SES area to participate in semi-structured interviews. Parents and children were asked questions around three prominent themes of social exclusion; exclusion from school, social activities and social networks.

Results: Many children experienced social exclusion at school, from social activities or within social networks. Overall, nine key barriers to social inclusion were identified through parent and child interviews, such as inability to attend school camps and participate in school activities, bullying and being left out, time and transport constraints, financial constraints and safety and traffic concerns. Parents and children often identified different barriers.

Discussion: There are several barriers to social inclusion for children living in low SES communities, many of which can be used to facilitate mental health promotion programmes. Given that parents and children may report different barriers, it is important to seek both perspectives.

Conclusion: This study strengthens the evidence base for the investments and action required to bring about the conditions for social inclusion for children living in low SES communities.

Adventures of punctuated equilibria : a struggle for authority in the evolutionary sciences

The theory of ‘punctuated equilibria’ was formulated by two paleontologists, Niles Eldredge and Stephen Gould, in 1972 and has been the focus of considerable controversy within the evolutionary sciences ever since. The primary intentions of this thesis are to relate the history of punctuated equilibria and to examine how it has affected evolutionary science. Several modes of analysis have been used to illuminate the history: The sociological perspectives of Pierre Bourdieu and Bruno Latour (who see scientific debate as a ‘struggle for authority’); Rhetorical analysis of some of the key documents; Communication with practising scientists via questionnaires and correspondence; Citation Analysis. Chapter 1 gives a short summary of the history and introduces the methods and socio-philosophical perspectives used to illuminate the history. Chapters 3 and 4 examine the rhetorical process by which Eldredge and Gould constructed the ‘punctuationist revolution’. Chapters 2, 3, 5 and 6 relate the history of punctuated equilibria.

Parental socialisation of preschool children's food preferences

The research examined parental socialisation of preschool children's food preferences. The findings indicated that parents' beliefs, child characteristics and parents' feeding behaviours contribute to children's food preferences. In particular, parents' self-efficacy beliefs and beliefs about why children reject foods on the one hand, and children's food neophobia on the other hand appear to influence children's everyday food preferences.

Assessing the legitimacy of humanitarian intervention : purpose, authority and means

This study looked at military deployments that seek to promote human rights, including operations in Somalia, Rwanda and Kosovo. While a legitimate humanitarian purpose and international authority for these missions can be demonstrated, finding the appropriate means of action - or how to best conduct the operation - remains very difficult, ensuring similar future missions will remain controversial.

Parental influences upon their children's body image concerns and behaviours

An examination of the influence of parents revealed that sons' and daughters' perceptions of the direct and indirect pressures exerted by both mothers and fathers were more predictive of their body image concerns and body change strategies than the messages reported by parents. The professional portfolio presents four case studies of children referred to a Child and Adolescent Mental Health Service with depressive symptomatology in relation to attachment theory.

The impact of parental multiple sclerosis on the adjustment of children and adolescents.

Thirty-one parents with multiple sclerosis (MS) participated in a study to investigate the adjustment of their children, 24 boys and 24 girls aged 4 to 16 years. The majority of parents believed that their illness had an effect on their children. The perception of parents regarding their children's problems in the areas of emotions, concentration, behavior, or social interactions indicated that the children were at three times greater risk than the general community of developing psychological problems. In contrast, actual symptom scores reported by parents revealed that, although these children were at greater risk than the general community of developing peer problems, little difference was found on hyperactivity, emotional symptoms, conduct problems, or total difficulties. Parental negative affect predicted both parental reports of peer problems and perceptions that the parents' illness had an effect on their children. Parental relationship satisfaction and family income did not predict parental reports of children's level of adjustment. These results indicate that children of parents with MS demonstrate more difficulties in how they relate to others, the distress they experience, and how they manage their lives, rather than revealing higher levels of symptoms. Since the data were based on parental reports of their children's problems, the results may also be due to negative affect among the parents.

Prenatal environmental effects match offspring begging to parental provisioning

The solicitation behaviours performed by dependent young are under selection from the environment created by their parents, as well as wider ecological conditions. Here we show how mechanisms acting before hatching enable canary offspring to adapt their begging behaviour to a variable post-hatching world. Cross-fostering experiments revealed that canary nestling begging intensity is positively correlated with the provisioning level of their own parents (to foster chicks). When we experimentally increased food quality before and during egg laying, mothers showed higher faecal androgen levels and so did their nestlings, even when they were cross-fostered before hatching to be reared by foster mothers that had been exposed to a standard regime of food quality. Higher parental androgen levels were correlated with greater levels of post-hatching parental provisioning and (we have previously shown) increased faecal androgens in chicks were associated with greater begging intensity. We conclude that androgens mediate environmentally induced plasticity in the expression of both parental and offspring traits, which remain correlated as a result of prenatal effects, probably acting within the egg. Offspring can thus adapt their begging intensity to variable family and ecological environments.

Parental perceptions of residential location : impacts on children's health

This study explored families’ views and experiences of their residential location in relation to their children's health. Thematic analysis of interviews with mothers revealed that decisions to live in an outer Melbourne municipality were strongly influenced by ideals around children however; all spoke of experiencing difficulties in raising children in terms of accessing services, recreation facilities, transport and work. Analysis of these findings using Bronfenbrenner's Social Ecology Model revealed how factors could interact to affect children's health and wellbeing. The study findings highlight the importance of parental perceptions of residential location in understanding the relationship between children's health and place.

Effects of parental perception of neighbourhood deprivation and family environment characteristics on pro-social behaviours among 4-12 year old children

Objective : To assess the effect family environment stressors (e.g. poor family functioning and parental psychological distress) and neighbourhood environment on child prosocial behaviour (CPB) and child difficulty behaviour (CDB) among 4-to-12 year old children.

Methods : Analysis of the 2006 Victorian Child Health and Wellbeing Survey (VCHWS) dataset derived from a statewide cross-sectional telephone survey, with a final total sample of 3,370 children.

Results : Only family functioning, parental psychological distress, child gender, and age were associated with CPB, explaining a total of 8% of the variance. Children from healthily functioning families and of parents without any psychological distress exhibited greater prosocial behaviours than those from poorly functioning families and of parents with mental health problems. Neighbourhood environment was not found to contribute to CPB. A total of eight variables were found to predict CDB, explaining a total of 16% of the variance. Poor family and parental psychological functioning as well as poor access to public facilities in the neighbourhood were associated with conduct problems in children.

Conclusion : Our results point to the importance of the family environment in providing a context that fosters the development of empathic, caring and responsible children; and in buffering children in exhibiting behaviour difficulties during the formative years of life. Programs aimed at promoting prosocial behaviours in children need to target stressors on the family environment.

Does family intervention for adolescent substance use impact parental wellbeing?

Adolescent substance abuse is a prevalent problem and family interventions are increasingly used to prevent this problem and to assist family coping. The effectiveness of a prevention-focussed family intervention was evaluated within a randomised school trial for its secondary impacts on improving parental mental health and family functioning.
