Investigating the neurodevelopmental mediators of aggression in children with a history of child maltreatment:An exploratory field study.

Maltreatment of children is a chronic community problem that increases the risk of future aggression. Despite several decades of research highlighting this relationship, few studies have explored the potential neuropsychological deficits that are likely to mediate it. This exploratory study aimed to examine how child maltreatment may be associated with aggression via impairment in the developing prefrontal-limbic-autonomic pathways that are implicated in neuropsychological models of aggression. Furthermore, it aimed to investigate the relationship between child maltreatment and both reactive and proactive aggression subtypes. To investigate this non-invasively in an at-risk population, children with a documented protective care history (n = 20) and a community control group (n = 30), aged between 6 and 12 years, were compared on measures of cardiovascular functioning, affect regulation and cognitive functioning aligned with this neuropsychological model. Whilst no group differences were found on cardiovascular functioning (i.e., resting heart rate, heart rate reactivity, heart rate variability), the protective care group performed significantly worse on measures of affect regulation and cognitive functioning (i.e., global intelligence, executive functioning, smell identification and social cognition). The relationship between child maltreatment and aggression was mediated by executive dysfunction and affect dysregulation but not global IQ, social cognition or olfactory identification. The results suggest that interventions targeting aggression in maltreated children will benefit from clinical assessment and psychological strategies that address the executive dysfunction and affect dysregulation that has been associated with this clinical outcome.

Parental experiences of their infant's hospitalization for cardiac surgery.

BACKGROUND: Parents are increasingly recognized as important partners in children's health care. Despite their involvement in care, parental experiences of their child's hospitalization have received little research attention. In this study we explored parents' perceptions of what they found difficult, what they would like to be different and what they found to be helpful during their infant's hospitalization and surgery for the treatment of congenital heart disease. METHODS: Structured interviews were conducted with 154 parents (91 mothers, 63 fathers) whose infant underwent cardiac surgery (at <3 months of age) 1 month post discharge from hospital. Thematic and frequency analyses were performed. RESULTS: Parents reported a range of difficulties from dealing with their baby's unfolding illness, surgery and recovery to the structural and systemic issues associated with the broader context of their experiences. In an effort to be near their baby, parents struggled to obtain the necessities for daily living at the hospital and negotiate transitions between their hospital and home lives throughout the admission. Domains parents identified for change included the availability of facilities and resources and the quantity and quality of information and emotional support. Parents reported relationships with hospital staff as the most common source of support during this challenging time. CONCLUSIONS: Opportunities to improve parents' experiences when their infant is in hospital exist at an organizational level as well as at the clinical level. The significance of parents' relationship with hospital staff indicates the potential for each professional to impact on families' experiences on a daily basis. The range of challenges indicates the scope and need for allied health services.

Reducing and preventing internalizing and externalizing behavior problems in children with type 1 diabetes: a randomized controlled trial of the Triple P-Positive Parenting Program.

BACKGROUND: Children with type 1 diabetes are at increased risk of mental health problems, which in turn are associated with poor glycemic control, diabetes-related complications, and long-term psychiatric morbidity. We tested the efficacy of the Triple P-Positive Parenting Program in reducing or preventing mental health problems and improving glycemic control in children with type 1 diabetes in a randomized controlled trial. METHODS: Participants were recruited from the Diabetes Clinic, Royal Children's Hospital, Melbourne, Australia, and randomized to Triple P or standard diabetes care. The primary outcome was child internalizing and externalizing behavior problems 3 and 12 months postrandomization. Secondary outcomes were glycemic control, parent mental health, parenting skills, and family functioning at 3 and 12 months, and glycemic control at 24 months. RESULTS: A total of 76 participants were randomized (38 to intervention and 38 to control), 60 completed 3-month, and 57 completed 12-month assessments. Benefits of Triple P were evident at 3 months for parent mental health, parenting skills, and family functioning (p < 0.05), but not for child mental health or glycemic control, with little effect at 12 months. Prespecified subgroup analyses for children with pre-existing internalizing or externalizing behavior problems indicated greater improvements in child mental health, parent mental health, parenting skills, and diabetes family conflict (p < 0.05), but lower parenting self-efficacy at 3 months. Improvements in parent mental health and parenting competency associated with Triple P were sustained to 12 months for children with pre-existing mental health problems. CONCLUSIONS: This study provides some support for the efficacy of Triple P in improving parent and family outcomes, and reducing child internalizing and externalizing behavior problems primarily in children who have pre-existing mental health problems.

Adapting a generic coping skills programme for adolescents with type 1 diabetes: a qualitative study.

Few qualitative studies have examined the views of adolescents with type 1 diabetes mellitus (T1DM) regarding psychosocial programme development and content. We conducted focus groups with 13 adolescents with T1DM to explore stressors and gain feedback on adapting a generic coping skills programme. The following prevalent stressors were identified: parental/adolescent conflict, balancing self-management and daily life, and health concerns. Prevalent views on programme adaptation included enhancing social support and adding diabetes-specific information and skills. Based on these data, the programme was adapted to address stressors and support self-management, thus better meeting the needs of, and appeal to, adolescents with T1DM.

Longitudinal predictors of psychiatric disorders in very low birth weight adults.

The purpose of this study was to determine risk and protective factors for adult psychiatric disorders in very low birth weight (VLBW, birth weight <1,501 g) survivors. 79 of 154 (51%) VLBW subjects recruited at birth were assessed in early adulthood (24-27 years). Participants were screened for a psychiatric disorder; those elevated were invited to attend a structured clinical interview to determine a clinical diagnosis. Longitudinal variables measured from birth and at ages 2, 5, 14 and 18 years were included in analyses. Perinatal, developmental and social environmental risk factors failed to predict psychiatric disorder in adulthood in this cohort of VLBW survivors. Instead, low self-esteem at age 18 (odds ratio [OR] = 1.05, 95% confidence interval [CI] = 1, 1.11, p = 0.05) and the adult social environment (high rates of negative life event stress at the time of assessment: OR = 1.39, CI = 1.10, 1.76, p = 0.02), contributed significantly to adult psychiatric outcomes.

Behaviour and metabolic control in children with Type 1 diabetes mellitus on insulin pump therapy: 2-year follow-up.

AIMS: This study investigated whether continuous subcutaneous insulin infusion is associated with sustained improvement in behaviour and metabolic control. METHODS: Children with Type 1 diabetes mellitus (n = 27, 8-18 years old) who had been assessed previously prior to commencing continuous subcutaneous insulin infusion, and 6-8 weeks later, were re-evaluated 2 years after commencing insulin pump therapy. Behaviour was reassessed using the Behavioral Assessment System for Children-2nd edition (BASC-2) and current HbA(1c) levels were recorded. RESULTS: Two years after commencing continuous subcutaneous insulin infusion, parent-reported internalizing and externalizing symptoms were significantly lower than pre-insulin pump therapy commencement levels. Self reports of internalizing and externalizing problems did not differ significantly across the three assessment points. There was no significant difference between pre-insulin pump therapy HbA(1c) and HbA(1c) after 2 years on continuous subcutaneous insulin infusion, despite an initial improvement 6-8 weeks after commencing the therapy. CONCLUSIONS: Children with Type 1 diabetes mellitus showed sustained improvements in parent-reported behaviour, but not in self reports of behaviour or in metabolic control 2 years after commencement of continuous subcutaneous insulin infusion.

Psychological adjustment of well siblings of children with Type 1 diabetes.

AIMS: Studies of siblings of children with Type 1 diabetes (Type 1 DM) have shown either increased levels of maladjustment or, alternatively, increased levels of pro-social behaviour according to whether the sibling or parent was interviewed. The purpose of this study was to examine the psychological adjustment of Type 1 DM siblings using both parent and sibling report and to assess the concordance between child and parent reports. METHODS: Ninety-nine siblings aged 11-17 years and parents of children with Type 1 DM treated at the Royal Children's Hospital, Melbourne were recruited sequentially. The Strengths and Difficulties Questionnaire (SDQ) was used to assess well siblings' emotional and behavioural functioning using data collected within a semi-structured interview. SDQ data between the sibling cohort and normative data sample were compared using independent-samples t-tests. Sibling reports and parent reports were compared using a series of paired-sample t-tests and correlation analyses. RESULTS: Type 1 DM siblings did not report greater emotional or behavioural maladjustment or more pro-social behaviour than norms. Parents rated siblings' pro-social behaviour as being comparable with that of youth from the general community; however, parents rated healthy siblings as having lower levels of maladjustment; specifically, significantly fewer conduct problems, hyperactive behaviour and peer-related problems (all P < 0.01). There were no significant differences between parent ratings and sibling ratings on peer-related problems or pro-social behaviour. CONCLUSIONS: Type 1 DM siblings did not report increased behavioural or emotional dysfunction relative to children in the general population and, according to their parents, were even better adjusted than their peers.

Improvements in cognition, mood and behaviour following commencement of continuous subcutaneous insulin infusion therapy in children with type 1 diabetes mellitus: a pilot study.

AIMS/HYPOTHESIS: Anecdotally, parents and teachers of children with type 1 diabetes mellitus report improvements in behaviour and learning following the commencement of continuous subcutaneous insulin infusion (CSII). This study aimed to investigate changes in cognition, mood and behaviour following commencement of CSII in children with type 1 diabetes. METHODS: Children (n = 32) with type 1 diabetes aged 6-16 years and starting CSII at two Australian centres underwent behavioural, cognitive and glycaemic assessments prior to the commencement of CSII and 6-8 weeks after its start. A comprehensive cognitive test battery was administered, comprising measures of intelligence, attention, processing speed and executive skills. Behaviour and mood were assessed using the Behaviour Assessment System for Children--Second Edition. Continuous glucose monitoring was performed over a 72 h period and HbA(1c) was measured at both time-points. RESULTS: After commencement of CSII, there were significant improvements in HbA(1c), a reduction in hyperglycaemia and blood glucose variation and an increase in normoglycaemia. Significant improvements were observed in perceptual reasoning, selective attention, divided attention, cognitive flexibility and working memory. Fewer mood-related symptoms were reported (parent, teacher and self-report) and fewer behavioural problems (parent reports) CONCLUSIONS/INTERPRETATION: In this uncontrolled pilot study, children with type 1 diabetes demonstrated significant improvements in measures of metabolic control, mood and behaviour and in some complex cognitive skills after commencing CSII therapy.

Quality of life and gender role behavior in disorders of sexual differentiation in India.

OBJECTIVE: Culture-specific tools to assess longterm psychosocial outcomes for patients with disorders of sexual differentiation are scant. We conducted a study to develop tools for evaluating gender role behavior and health related quality of life for Indian adolescent patients with intersex disorders. We also studied factors important to parents while deciding sex of rearing for their baby. METHODS: A 29-item gender role behavior questionnaire and an 18-item health related quality-of-life questionnaire were administered to 82 healthy controls, 13 patients with intersex disorders and 18 patients with type 1 diabetes mellitus. Internal consistency was checked by Cronbach's alpha and test-retest reliability using intra-class correlation coefficient. Responses of 28 parents to a questionnaire on factors affecting the decision of sex of rearing were recorded on a 5-point Likert scale in order of importance. RESULTS: Cronbach's alpha was 0.92 and 0.75, and intra-class correlation coefficient 0.76 and 0.75, for the gender role behavior and quality-of-life questionnaires respectively, indicating a high degree of internal consistency and stability. The mean composite scores for healthy girls on the gender role behavior questionnaire (82.5 +/- 8.7) differed significantly from that for healthy boys (53.2 +/- 7.1, p <0.001). Factors important to parents while making decisions for sex of rearing were appearance of the genitalia, medical advice, ability to bear children and economic independence. CONCLUSIONS: We have created valid tools to study gender role behavior and quality of life in adolescent patients with intersex disorders in India. We have also identified in a quantitative way the factors of greatest importance to parents while deciding sex of rearing. These results have direct utility in the management of patients with intersex disorders in India and other similar cultures.

Interventions to promote optimal health outcomes in children with Type 1 diabetes--are they effective?

The incidence of Type 1 diabetes is increasing worldwide, imposing enormous public health costs, as well as profoundly affecting individual quality of life. There is evidence that psychological problems are increased in children with diabetes and this morbidity is often associated with poor metabolic control. Specific risk factors for this dual morbidity are emerging from empirical studies. The next challenge is to identify effective interventions for use with children at risk for adverse mental and physical health outcomes. The intervention literature is reviewed. It is noted that most studies have used diabetes-specific, unstandardized interventions in groups of adolescents, with few interventions trialled with younger children. No study has targeted a specific psychological disorder such as behaviour problems or depression, both of which are known to be increased in children with diabetes and for which effective standardized interventions are available. Attention is drawn to methodological limitations in many of the studies conducted to date and suggestions made to reduce these in future interventions attempting to reduce the burden of illness in children with diabetes.

Childhood precursors of adolescent outcomes in type 1 diabetes mellitus.

Contemporary outcome measures of chronic illnesses such as type 1 diabetes mellitus are broader than those clinical outcomes traditionally assessed in therapeutic encounters. A holistic approach emphasises quality of life and emotional well-being as well as the achievement of optimal disease management. This paper reviews current knowledge about growth, metabolic control, diabetes complications, neurocognitive and psychological outcomes as well as health-related quality of life in childhood diabetes mellitus. It is suggested that the antecedents of adverse diabetes and psychological outcomes in adolescence lie in the years prior to adolescence. The model of care in childhood diabetes mellitus must be focussed on earlier screening and intervention if adverse outcomes are to be reduced.

Psychiatric morbidity and health outcome in Type 1 diabetes--perspectives from a prospective longitudinal study.

AIMS: To describe psychiatric status and relationship to metabolic control in adolescents with Type 1 diabetes studied prospectively from diagnosis. METHODS: Adolescents (n = 41) completed a self-report measure of psychiatric status 10 years after disease onset. Metabolic control information was recorded prospectively from diagnosis. The rate and type of psychiatric disorder were determined and the relationship between mental health status and metabolic control history examined. RESULTS: Thirty-seven per cent of the adolescents met criteria for a DSM-IV psychiatric disorder, two to three times higher than community levels of psychiatric morbidity. Females were significantly more likely to receive a diagnoses (chi2 = 4.98, P < 0.05). Two thirds of participants had experienced at least one serious hypoglycaemic episode and one third had a history of chronic poor metabolic control. DSM-IV diagnoses were present in half of those with a history of chronic poor control, one third of the hypoglycaemia group and one quarter of well controlled participants. Adolescents with a current Mood (t = -2.83, P < 0. 01), Anxiety (t = -3.77, P = 0.001) or Behaviour (t = 2.56, P < 0.05) disorder and those with a history of poorly controlled diabetes (F (2,29) = 5.4, P = 0.01) had higher externalizing behaviour problem scores at diagnosis than those without current disorder. CONCLUSIONS: Adolescents with Type 1 diabetes are at high risk for psychiatric disorder. Poorly controlled diabetes over the first 10 years of illness was associated with pre-existing behaviour problems at diagnosis and there was a trend for an association with current psychiatric status.

Early detection of emotional and behavioural problems in children with diabetes: the validity of the Child Health Questionnaire as a screening instrument.

AIMS: To assess the validity of the Child Health Questionnaire (CHQ) as a screening tool for detecting 'at risk' emotional and behavioural maladjustment in children with diabetes, using the Behaviour Assessment System for Children (BASC) as a gold standard measure. METHODS: CHQ and BASC were administered to 103 parents of children with Type 1 diabetes, aged 7-12 years. Sub-scales of the two measures were compared using Pearson's bivariate correlations. CHQ sensitivity and specificity cut-points were optimized against the BASC borderline category using receiver operating characteristic curves. RESULTS: The BASC Externalizing Problems scale correlated strongly with CHQ Behaviour, Global Behaviour, Mental Health, Family Activities and Family Cohesion scales (r-values -0.68, -0.54, -0.51, -0.59, and -0.42, respectively). BASC Internalizing Problems scale correlated strongly with CHQ Behaviour, Mental Health and Family Cohesion scales (r-values -0.40, -0.43 and -0.45, respectively). Using receiver operating characteristic curve analysis, the CHQ Mental Health scale most effectively identified children classified as borderline on the BASC Internalizing Problems scale (sensitivity 87%, specificity 78%), while the CHQ Global Behaviour scale most effectively identified children classified as borderline on the BASC Externalizing Problems scale (sensitivity 73%, specificity 82%). CONCLUSIONS: Significant correlations were seen between the CHQ Global Behaviour and Mental Health scales and the BASC Externalizing and Internalizing scales, respectively. Sequential use of the CHQ, as a screening tool, followed by an established mental health measure such as the BASC, may help identify children with diabetes 'at risk' for chronic maladjustment and poor health outcomes.

Neuropsychological profiles of children with type 1 diabetes 6 years after disease onset.

OBJECTIVE: To describe neuropsychological profiles and their relationship to metabolic control in children with type 1 diabetes 6 years after the onset of disease. RESEARCH DESIGN AND METHODS: Children with type 1 diabetes (n = 90), aged 6-17 years, who had previously been assessed soon after diagnosis and 2 years later, were reevaluated 6 years after the onset of disease. Their neuropsychological profiles were compared with those of individuals in a community control group (n = 84), who had been assessed at similar intervals. Relationships between illness variables, such as age at the onset of disease and metabolic control history, and neuropsychological status were also examined. RESULTS: Six years after onset of disease, children with type 1 diabetes performed more poorly than control subjects on measures of intelligence, attention, processing speed, long-term memory, and executive skills. Attention, processing speed, and executive skills were particularly affected in children with onset of disease before 4 years of age, whereas severe hypoglycemia was associated with lower verbal and full-scale intelligence quotient scores. CONCLUSIONS: Neuropsychological profiles of children with type 1 diabetes 6 years after the onset of disease are consistent with subtle compromise of anterior and medial temporal brain regions. Severe hypoglycemia, particularly in very young children, is the most plausible explanation for neuropsychological deficits, but the contributory role of chronic hyperglycemia warrants further exploration.

Development of executive functions through late childhood and adolescence in an Australian sample.

Although there have been significant theoretical advances in the field of child neuropsychology, developmental features of adolescence have received less attention. Progress in clinical practice is restricted due to a lack of well-standardized, developmentally appropriate assessment techniques. This article addresses these issues in relation to executive skills. These abilities are targeted for 2 reasons: first, because they are often considered to be mature during late childhood and adolescence, despite limited investigation in this age range; and second, because of their central importance to efficient day-to-day functioning. Using a normative sample of 138 children, aged 11.0 to 17.11 years, this article plots the development of executive skills through late childhood and early adolescence and interprets progress in these skills with reference to current neurological and cognitive theory.

Predictors of change in the neuropsychological profiles of children with type 1 diabetes 2 years after disease onset.

OBJECTIVE: To identify type 1 diabetes-related predictors of change in the neuropsychological profiles of children over the first 2 years of the illness. RESEARCH DESIGN AND METHODS: Children (n = 116) aged 3-14 years were assessed soon after diagnosis and re-evaluated 2 years later to examine relationships between illness variables, such as age of onset and metabolic control history, and changes in neuropsychological status over the first 2 years of type 1 diabetes. RESULTS: Illness variables were significant predictors of change in neuropsychological test scores within 2 years of onset of type 1 diabetes. Age of onset of type 1 diabetes predicted negative change on Performance Intelligence Quotient, whereas both recurrent severe hypoglycemia and chronic hyperglycemia were associated with reduced memory and learning capacity. CONCLUSIONS: These results suggest that the relationship between metabolic control and neuropsychological risk is nonlinear in that children with either recurrent severe hypoglycemia or chronically elevated blood sugars exhibit negative changes in their neuropsychological profiles. Onset of type 1 diabetes very early in life adds another dimension of risk, particularly affecting the acquisition of visuospatial skills.

Neuropsychological complications of IDDM in children 2 years after disease onset.

OBJECTIVE: To compare the neuropsychological profiles of children with IDDM with a community control group at two time points: 3 months after disease onset and 2 years after the baseline assessment. RESEARCH DESIGN AND METHODS: A total of 123 children (age 3-14 years) with recent IDDM onset were compared with 129 community control subjects, stratified for age and sex, on standardized measures of general intelligence, attention, speed of processing, memory, learning, executive skills, and behavioral adjustment soon after diagnosis and 2 years later. Exclusion criteria were premorbid evidence of central nervous system disease or trauma, or English not spoken in the home. RESULTS: There were no differences between children with IDDM and control subjects on any measure at the initial assessment 3 months after disease onset. Two years later, children with IDDM tended to show a less positive change, relative to control subjects, in their standardized scores on measures of general intelligence, and significantly so on the vocabulary (P < 0.01) and block design (P < 0.05) subtests. Multivariate group differences were also apparent on speed of processing (P < 0.05) and learning (P < 0.01) subtests, reflecting smaller developmental gains in the children with IDDM when compared with control subjects. CONCLUSIONS: The findings are consistent with previous reports, suggesting that IDDM is associated with an increased risk of mild neuropsychological dysfunction. The skills most affected in this cohort were information processing speed, acquisition of new knowledge, and conceptual reasoning abilities. Clinicians and educators should be made aware of the risk of specific neuropsychological deficits in children with IDDM.

Psychosocial impact of chronic illness in children.

Chronic illness is common in childhood and is associated with an increased risk of psychological difficulties in the child. Current research is focused on the identification of specific risk and protective factors that may predict psychological and health outcomes. The challenges faced by physicians caring for a child with chronic illness are described and contrasted with the medical role in treating acute illness. The child's adaptation to illness is discussed in a developmental framework and positive and maladaptive family responses are identified. It is suggested that chronic illness and/or its treatment may compromise intellectual development and academic progress.

Psychosocial and family functioning in children with insulin-dependent diabetes at diagnosis and one year later.

Examined the initial impact and subsequent adjustment to the diagnosis of insulin-dependent diabetes mellitus (IDDM). Children between 1 and 14 years of age and their families were assessed several weeks after diagnosis and again a year later using standardized measures of child behavior, parental mental health, and family functioning. Immediately after diagnosis, the children and both parents exhibited mild symptoms of psychological distress but these had largely resolved at 12-month follow-up. The impact of IDDM diagnosis on family functioning varied with informant, SES, and the age of the child, with an overall tendency for families to become less flexible over the year. Findings suggest that most children and their parents exhibit satisfactory individual adjustment after a period of initial stress but family functioning is affected in complex ways. Serial follow-up of the cohort is planned to establish whether the current findings are predictive of longer term outcome.

Secondary prevention of childhood firesetting.

OBJECTIVE: The Juvenile Fire Awareness and Intervention Program was established to develop and evaluate an intervention to be offered by fire fighters for children who set fires. METHOD: One hundred thirty-eight children, aged 5 to 16 years, with a history of firesetting participated in a randomized, controlled trial. The intervention involved education about fire safety and a behavior modification program designed to extinguish the desire to set fires through satiation. The frequency and severity of firesetting were recorded for 12 months after the intervention to measure outcome. RESULTS: There was a significant decrease in the frequency and severity of firesetting across all groups, with no additional improvement resulting from participation in the fire fighters' intervention. CONCLUSIONS: There is no evidence to suggest that the multicomponent program offered by trained fire fighters is effective in reducing firesetting. The marked reduction in firesetting across all groups suggests that fire safety education by the fire fighters is the most appropriate approach to this serious community problem.
