ABSTRACT

AIMS: Mental disorders cause high burden in adolescents, but adolescents often underutilise potentially beneficial treatments. Perceived need for and barriers to care may influence whether adolescents utilise services and which treatments they receive. Adolescents and parents are stakeholders in adolescent mental health care, but their perceptions regarding need for and barriers to care might differ. Understanding patterns of adolescent-parent agreement might help identify gaps in adolescent mental health care. METHODS: A nationally representative sample of Australian adolescents aged 13-17 and their parents (N = 2310), recruited between 2013-2014, were asked about perceived need for four types of adolescent mental health care (counselling, medication, information and skill training) and barriers to care. Perceived need was categorised as fully met, partially met, unmet, or no need. Cohen's kappa was used to assess adolescent-parent agreement. Multinomial logistic regressions were used to model variables associated with patterns of agreement. RESULTS: Almost half (46.5% (s.e. = 1.21)) of either adolescents or parents reported a perceived need for any type of care. For both groups, perceived need was greatest for counselling and lowest for medication. Identified needs were fully met for a third of adolescents. Adolescent-parent agreement on perceived need was fair (kappa = 0.25 (s.e. = 0.01)), but poor regarding the extent to which needs were met (kappa = -0.10 (s.e. = 0.02)). The lack of parental knowledge about adolescents' feelings was positively associated with adolescent-parent agreement that needs were partially met or unmet and disagreement about perceived need, compared to agreement that needs were fully met (relative risk ratio (RRR) = 1.91 (95% CI = 1.19-3.04) to RRR = 4.69 (95% CI = 2.38-9.28)). Having a probable disorder was positively associated with adolescent-parent agreement that needs were partially met or unmet (RRR = 2.86 (95% CI = 1.46-5.61)), and negatively with adolescent-parent disagreement on perceived need (RRR = 0.50 (95% CI = 0.30-0.82)). Adolescents reported most frequently attitudinal barriers to care (e.g. self-reliance: 55.1% (s.e. = 2.39)); parents most frequently reported that their child refused help (38.7% (s.e. = 2.69)). Adolescent-parent agreement was poor for attitudinal (kappa = -0.03 (s.e. = 0.06)) and slight for structural barriers (kappa = 0.02 (s.e. = 0.09)). CONCLUSIONS: There are gaps in the extent to which adolescent mental health care is meeting the needs of adolescents and their parents. It seems important to align adolescents' and parents' needs at the beginning and throughout treatment and to improve communication between adolescents and their parents. Both might provide opportunities to increase the likelihood that needs will be fully met. Campaigns directed towards adolescents and parents need to address different barriers to care. For adolescents, attitudinal barriers such as stigma and mental health literacy require attention.

ABSTRACT

BACKGROUND: The aim of this study was to estimate the association between two key aspects of self-regulation, 'task attentiveness' and 'emotional regulation' assessed from ages 2-3 to 6-7 years, and academic achievement when children were aged 6-7 years. METHODS: Participants (n = 3410) were children in the Longitudinal Study of Australian Children. Parents rated children's task attentiveness and emotional regulation abilities when children were aged 2-3, 4-5 and 6-7. Academic achievement was assessed using the Academic Rating Scale completed by teachers. Linear regression models were used to estimate the association between developmental trajectories (i.e. rate of change per year) of task attentiveness and emotional regulation, and academic achievement at 6-7 years. RESULTS: Improvements in task attentiveness between 2-3 and 6-7 years, adjusted for baseline levels of task attentiveness, child and family confounders, and children's receptive vocabulary and non-verbal reasoning skills at age 6-7 were associated with greater teacher-rated literacy [B = 0.05, 95% confidence interval (CI) = 0.04-0.06] and maths achievement (B = 0.04, 95% CI = 0.03-0.06) at 6-7 years. Improvements in emotional regulation, adjusting for baseline levels and covariates, were also associated with better teacher-rated literacy (B = 0.02, 95% CI = 0.01-0.04) but not with maths achievement (B = 0.01, 95% CI = -0.01-0.02) at 6-7 years. For literacy, improvements in task attentiveness had a stronger association with achievement at 6-7 years than improvements in emotional regulation. CONCLUSIONS: Our study shows that improved trajectories of task attentiveness from ages 2-3 to 6-7 years are associated with improved literacy and maths achievement during the early school years. Trajectories of improving emotional regulation showed smaller effects on academic outcomes. Results suggest that interventions that improve task attentiveness when children are aged 2-3 to 6-7 years have the potential to improve literacy and maths achievement during the early school years.

ABSTRACT

OBJECTIVE: To determine relationships between body mass index (BMI) status and indicators of health and morbidity in a nationally-representative population sample of preschool children. METHODS: Data from the 4-5-year-old cohort in the first wave (2004) of the Longitudinal Study of Australian Children were studied. Main outcome measures were: measured child BMI, categorised as non-overweight, overweight and obese using International Obesity TaskForce cutpoints; parent-reported child global health, health-related quality of life, mental health problems, asthma, sleep problems, injuries, special health care needs, and level of parental concern about the child's weight. Regression methods were used to assess associations with child's BMI status, adjusted for sociodemographic factors. RESULTS: BMI was available for 4934 (99%) children; 756 (15.3%) were overweight and 258 (5.2%) obese. Compared to non-overweight children, parents of overweight and obese children reported a higher prevalence of special health care needs (adj OR 1.72, 95% CI 1.20 to 2.46), but other health outcomes were similar. Parental concern about the child's weight was low among the overweight (14.4%) and non-overweight (17.8%) children, but rose to 52.7% in the obese. However, parental concern was unrelated to any of the specific health problems studied. CONCLUSIONS: Despite a high prevalence of overweight/obesity, parents of overweight and obese children reported relatively few additional health burdens over and above those of the non-overweight preschoolers. These findings may shed light on the disparity between strong public concern and parents' expressed lack of concern about overweight/obesity in their own children around the time of school entry.

ABSTRACT

The aim of this study was to assess prospectively changes in the health-related quality of life (HRQL) of children and adolescents with diabetes, asthma or cystic fibrosis (CF). One hundred and twenty-two parents of children aged 10-16 years with asthma, diabetes, or CF were recruited from specialist paediatric clinics. Parents described their children's HRQL using the Child Health Questionnaire (PF98) at baseline, 6, 12, 18 and 24 months post-baseline. They reported that the general health of children with CF was significantly worse than that of children with asthma and diabetes at baseline. In other domains there were few differences between the HRQL of children in the three groups. In several domains, the HRQL of children with asthma or diabetes improved over the 2 years of the study. This improvement was less evident for children with CF.

ABSTRACT

OBJECTIVES: To investigate the relationship between health-related quality of life (HRQL), experience of pain and pain coping strategies in children with juvenile idiopathic arthritis (JIA). To compare reports describing these variables obtained from children and their parents. METHODS: Participants were 59 children aged 8 to 18 yr with JIA and their parents. Parents and children completed the PedsQL generic core scales and arthritis module, the visual analogue scale of the Varni-Thompson Pediatric Pain Questionnaire, and the Waldron/Varni Pediatric Pain Coping Inventory. Parents rated children's functional disability using the Childhood Health Assessment Questionnaire. RESULTS: Parents reported significantly lower scores (indicating worse HRQL) than children on five of the eight PedsQL scales rating children's HRQL. Parents and children reported a significant negative relationship between pain levels and the PedsQL scores assessing children's physical, emotional and social functioning. They also reported a significant negative relationship between scores on several pain coping scales and scores on the PedsQL scales. However, the pattern of these relationships varied for reports from parents and children. CONCLUSIONS: Pain intensity and pain coping strategies have a significant and independent relationship with several domains that comprise the HRQL of children with JIA. However, parents and children have differing perceptions of the nature of these relationships. The differences emphasize the importance of clinicians obtaining information about children's HRQL, pain levels and pain coping strategies from both parents and children.

ABSTRACT

OBJECTIVES: The present study aims to describe the use of health services by children with asthma, and examine disease-specific, parental and sociodemographic variables associated with different levels of health-service utilization. METHODS: Parents of 135 children attending an emergency room (ER) completed questionnaires measuring the children's asthma symptoms, and sociodemographic and psychological variables. Parents were contacted monthly for 6 months to document the number of planned and unplanned visits to hospital and community health-care services for asthma. RESULTS: At least one further unplanned visit to the ER was made by 37% of children, while 62% made at least one unplanned visit to a general practitioner (GP). Fifty-five per cent made planned review visits to a GP, 30% to paediatricians and 5% to hospital clinics. After controlling for the level of asthma symptoms, parental anxiety and parental perceptions of children's vulnerability were associated with unplanned GP visits (P = 0.05 and P = 0.01, respectively); a planned review visit and the child being admitted to hospital for the index attack were associated with unplanned ER visits (P = 0.05 and P = 0.004, respectively). CONCLUSIONS: Children with asthma more frequently attend GP services than hospital services for both planned and unplanned asthma management. Different variables predict the unplanned use of GP and ER services. Understanding these differences is imperative if children and families are to make the most effective use of health services.

ABSTRACT

OBJECTIVES: To examine the prevalence and factors associated with depression in Australian adolescents. DESIGN: A representative, multistage probability sample of Australian households conducted in 1998 (part of the National Survey of Mental Health and Well-being). Adolescents completed self-report questionnaires and parents were interviewed using a lay-administered, structured psychiatric interview and several questionnaires. PARTICIPANTS: 1,490 adolescents aged 13-17 years and their parent or main caregiver. MAIN OUTCOME MEASURES: Prevalence of depression in adolescents, as reported by parents and by adolescents themselves; demographic factors; health-risk behaviours; and rate of use of support services. RESULTS: Of the 1,490 adolescents originally sampled, 150 (10%) did not complete responses to questions on depression and were excluded from the analysis. Seventy of the remaining 1340 adolescents (5.2%; 95% CI, 4.0%-6.4%) met criteria for self-reported depression. Agreement between parent- and adolescent-reported depression was poor (kappa=0.27). Adolescent-reported depression was associated with increased suicide plans (odds ratio [OR], 2.83; 95% CI, 1.19-6.70) and attempts (OR, 9.05; 95% CI, 3.49-23.50) in the previous year, use of marijuana 10 or more times in the previous month (OR, 2.88; 95% CI, 1.25-6.64), having conduct disorder (OR, 4.09; 95% CI, 1.23-13.63) and use of school support services (OR, 4.71; 95% CI, 1.82-12.22). Those who used any kind of support service (24/70; 34%) used a mean of 2.9 services (mode, 2; range, 1-5). Three per cent (2/70) of depressed adolescents had been treated with antidepressants. CONCLUSIONS: Depressed adolescents exhibit higher rates of health-risk behaviours and psychosocial impairment than non-depressed adolescents, but only a small number receive appropriate treatment. Staff working in school-based services should be trained to identify adolescents with depression and facilitate referral for treatment.

ABSTRACT

The quality of life of 84 children with asthma, aged 7-12 years, and their family functioning was assessed using standard questionnaires. A significant relationship was found between children's reports of their quality of life and several key dimensions of family functioning. The results suggest that independent of their frequency, the extent to which asthma symptoms upset and bother children varies depending on the level of the functioning of the children's families. Treatment approaches designed to improve family functioning may reduce the extent to which children are bothered by their asthma symptoms and thus improve their quality of life.

ABSTRACT

OBJECTIVE: To identify the prevalence of three mental disorders (Depressive Disorder, Conduct Disorder and Attention-Deficit/Hyperactivity Disorder), the prevalence of mental health problems, the health-related quality of life of those with problems, and patterns of service utilisation of those with and without mental health problems, among 4-17-year-olds in Australia. To identify rates of health-risk behaviours among adolescents with mental health problems. METHOD: The mental disorders were assessed using the parent-version of the Diagnostic Interview Schedule for Children Version IV. Parents completed the Child Behaviour Checklist to identify mental health problems and standard questionnaires to assess health-related quality of life and service use. The Youth Risk Behaviour Questionnaire completed by adolescents was employed to identify health-risk behaviours. RESULTS: Fourteen percent of children and adolescents were identified as having mental health problems. Many of those with mental health problems had problems in other areas of their lives and were at increased risk for suicidal behaviour. Only 25% of those with mental health problems had attended a professional service during the six months prior to the survey. CONCLUSION: Child and adolescent mental health problems are an important public health problem in Australia. The appropriate balance between funding provided for clinical interventions focusing on individual children and families and funding for interventions that focus on populations, requires careful study. The latter are an essential component of any strategy to reduce mental health problems as the high prevalence of problems makes it unlikely that individual care will ever be available for all those needing help. Clinical and population health interventions must take into account the comorbid problems experienced by children with mental disorders.

ABSTRACT

OBJECTIVE: To examine the discriminant validity of DSM-IV attention-deficit/hyperactivity disorder (ADHD) subtypes in a nationally representative sample of Australian youths. METHOD: The Diagnostic Interview Schedule for Children, including the symptom-specific impairment questions, was administered to 3,597 parents of children aged 6 to 17 years (response rate = 70%). Parents also completed questionnaires assessing children's emotional and behavioral problems and quality of life. RESULTS: Current DSM-IVADHD prevalence was 7.5% (6.8% with impairment) with inattentive types being more common than hyperactive-impulsive and combined types. ADHD was more prevalent among young males and was linked to social adversity, particularly for combined types. Compared with non-ADHD controls, all three ADHD subtypes were rated as having more emotional and behavioral problems and lower psychosocial quality of life, with combined types consistently rated the most impaired. Combined types received higher ratings than hyperactive-impulsive and inattentive types on externalizing behavior problems, disruption to family activities, and symptom-specific impairments with schoolwork and peer-related activities. Inattentive types were rated as having lower self-esteem, more social and school-related problems, but fewer externalizing problems than hyperactive-impulsive types. CONCLUSION: These findings support the view of DSM-IVADHD subtypes as distinct clinical entities with impairments in multiple domains.

ABSTRACT

OBJECTIVE: To investigate the impact on mothers and families of caring for a premature infant receiving home oxygen therapy (HOT). METHODS: Standard questionnaires were used to compare the functioning of mothers and families of 10 premature infants receiving HOT, 10 premature infants who were discharged from hospital on HOT but who no longer required it and 20 premature infants who had never required treatment with HOT. RESULTS: After adjustment for gestational age, chronological age, birthweight and place of residence (urban/rural), the care required by premature infants receiving HOT had a significantly greater impact on their families than the care of infants not receiving HOT. Mothers of premature infants receiving HOT reported significantly less vitality and more mental health problems than mothers of infants not receiving HOT. CONCLUSIONS: The use of HOT for premature infants may have a significant adverse impact on their mothers and families.

ABSTRACT

OBJECTIVE: This paper describes the Child and Adolescent Component of the National Survey of Mental Health and Wellbeing. METHOD: The aims of the study, critical decisions in planning for the study, progress to date and key issues which influenced the course of the study are described. RESULTS: The Child and Adolescent Component of the National Survey of Mental Health and Wellbeing is the largest study of child and adolescent mental health conducted in Australia and one of the few national studies to be conducted in the world. Results from the study will provide the first national picture of child and adolescent mental health in Australia. CONCLUSIONS: Large-scale epidemiological studies have the potential to provide considerable information about the mental health of children and adolescents. However, having a clear set of aims, ensuring that the scope of the study remains within manageable proportions and paying careful attention to the details of fieldwork are essential to ensure that high-quality data is obtained in such studies.

ABSTRACT

PURPOSE: To identify and compare perceived supportive and nonsupportive behaviors exhibited by family members and friends toward adolescents with cystic fibrosis (CF), and to examine the relationships between supportive and nonsupportive behaviors and adolescents' psychological adjustment. METHOD: Participants were 35 adolescents with CF attending the Women's and Children's Hospital in South Australia. Perceived supportive and nonsupportive behaviors were assessed using an adapted version of the Chronic Disease Support Interview. The psychological adjustment of the adolescents was assessed using the Youth Self Report Form. Repeated-measures analyses of variance were performed to compare the support provided by family members and friends. Multiple regression analyses assessed the contribution of supportive and nonsupportive behaviors for the prediction of psychological adjustment. RESULTS: Family members provided more tangible support than friends who, conversely, provided more companionship support. Overall, family members scored higher than friends on ratings for supportive behaviors. No differences were observed between family members and friends on ratings for nonsupportive behaviors. Rating of nonsupportive behaviors for family members was found to be the strongest predictor of psychological adjustment. CONCLUSIONS: Family members and friends provide different types of support. Family members provide more tangible help with treatment tasks and adolescents provide more companionship. Overall, this study demonstrated the importance of addressing nonsupportive as well as supportive behaviors when investigating the impact of support on the psychological adjustment of adolescents with a chronic illness.

ABSTRACT

This study examined the relationship between asthma management strategies used by parents and parental perception of children's vulnerability to illness. Home interviews were conducted with 101 parents of children previously hospitalized with asthma. The child vulnerability scale (CVS) was employed to assess parents' perception of their children's vulnerability to illness. The asthma severity index (ASI) was used to measure the frequency and intensity of asthma symptoms experienced by children in the preceding 12 months. Five markers of parental asthma management were assessed: (i) school absences; (ii) visits to the general practitioner (GP); (iii) visits to the emergency room (ER); (iv) hospitalizations; and (v) whether children are using a regular preventer. After controlling for the frequency and intensity of children's asthma symptoms, parents who perceived that their children were more vulnerable to medical illness were significantly more likely to keep their children home from school (P = 0.01), were more likely to take their children to the GP for acute asthma care (P = 0.02), and were more likely to be giving their children regular preventer medication (P = 0.02). In contrast, the use of tertiary pediatric care services was not significantly associated with parental perceptions of their children's vulnerability. The results suggest that parental attitudes and beliefs about the vulnerability of their children to illness were associated with greater use of GP services by parents and more frequent school absences for children. The use of hospital services by parents appeared to be more strongly associated with the actual level of children's asthma symptoms than their vulnerability to illness.

ABSTRACT

This study compared the health-related quality of life (HRQL) of 236 children with mild or moderate/severe asthma with that of a large representative sample of children in the general community. The study also examined the relationship between the HRQL of children with asthma and their demographic characteristics, asthma severity and family functioning. Children with asthma had a significantly poorer HRQL than other children in the community. Amongst the children with asthma, parents reported that children living in single-parent families had poorer physical health, mental health and social functioning than children in two-parent families. There was a significant relationship between the mental health of children with asthma and family functioning but no significant relationship between their physical health and family functioning. These findings suggest that the domains comprising the HRQL of children with asthma are related to both disease and non-disease factors. A better understanding of these relationships will facilitate the development of new interventions to help children with asthma.

ABSTRACT

This longitudinal investigation extends our prospective study of the intellectual and academic functioning of children treated for cancer to 4 years after diagnosis. In the longer term, the children who received central nervous system (CNS) chemotherapy experienced greater neurocognitive deficits, particularly in the area of academic achievement, than did the children who did not receive CNS chemotherapy. Specifically, the CNS chemotherapy-treated children scored lower on academic tests of reading at 3 and 4 years after diagnosis. The results suggest that CNS chemotherapy prophylaxis may adversely effect the development of higher-order mental abilities and cognitive skills during the late-effects period and may also impair academic achievement.

ABSTRACT

The Port Pirie Cohort Study is the first study to monitor prospectively the association between lifetime blood lead exposure and the prevalence of emotional and behavioral problems experienced by children. Lead exposure data along with ratings on the Child Behavior Checklist were obtained for 322 11-13-year-old children from the lead smelting community of Port Pirie, Australia. Mean total behavior problem score (95% confidence interval (CI)) for boys whose lifetime average blood lead concentration was above 15 microg/dl was 28.7 (24.6-32.8) compared with 21.1 (17.5-24.8) in boys with lower exposure levels. The corresponding mean scores (95% CI) for girls were 29.7 (25.3-34.2) and 18.0 (14.7-21.3). After controlling for a number of confounding variables, including the quality of the child's HOME environment (assessed by Home Observation for Measurement of the Environment), maternal psychopathology, and the child's IQ, regression modeling predicted that for a hypothetical increase in lifetime blood lead exposure from 10 to 30 microg/dl, the externalizing behavior problem score would increase by 3.5 in boys (95% CI 1.6-5.4), and by 1.8 (95% CI -0.1 to 11.1) in girls. Internalizing behavior problem scores were predicted to rise by 2.1 (95% CI 0.0-4.2) in girls but by only 0.8 (95% CI -0.9 to 2.4) in boys.

ABSTRACT

OBJECTIVE: To describe the determinants of blood lead concentration in children with long term environmental exposure to lead. DESIGN: Prospective cohort study. SETTING: The lead smelting town of Port Pirie, South Australia, and surrounding townships. PARTICIPANTS: 326 children born in and around Port Pirie, 1979-1982, followed up until age 11-13 years in 1993-1994. MAIN OUTCOME MEASURES: Blood lead concentrations assessed at birth and at multiple ages up to 11-13 years; average lifetime blood lead concentration. RESULTS: Mean blood lead concentration rose sharply over the ages 6 to 15 months, reached a maximum around 2 years of age, and declined steadily as the children grew older. There was no difference in blood lead concentration between boys and girls until they reached the age of 11-13 years, when mean blood lead concentration in boys (8.4 micrograms/dL [0.41 mumol/L]) was slightly higher than in girls (7.5 micrograms/dL [0.36 mumol/L]). Residential area and father's employment site were the two variables most strongly predictive of a child's blood lead concentration at the end of primary school. Poorer-quality home environment was also found to be an independent contributor to blood lead concentrations. CONCLUSIONS: Age-related factors, and possibly recent concerted efforts to decrease entry or re-entrainment of lead into the environment at Port Pirie, have resulted in most children in our study having blood lead concentrations below 10 micrograms/dL (0.48 mumol/L) at the end of their primary school years.

ABSTRACT

CONTEXT: Many studies have found a significant inverse association between early exposure to environmental lead and cognitive function in childhood. Whether these effects are reversible when exposure is reduced is not clear. OBJECTIVE: To assess the reversibility of the apparent effects of lead on cognitive abilities in early childhood by testing whether declines in blood lead concentrations beyond the age of 2 years are associated with improvements in cognition. SETTING: Urban and rural communities surrounding a large lead smelter in Port Pirie, South Australia. PARTICIPANTS: A total of 375 children followed up from birth to the age of 11 to 13 years. DESIGN: Long-term prospective cohort study. MAIN OUTCOME MEASURES: The Bayley Mental Development Index at age 2 years, the McCarthy General Cognitive Index at age 4 years, and IQs from the Wechsler Intelligence Scale (revised version) at ages 7 and 11 to 13 years. RESULTS: Mean blood lead concentrations in the children decreased from 1.02 pmol/L (21 .2 microg/dL) at age 2 years to 0.38 micromol/L (7.9 microg/dL) at age 1 1 to 13 years, but cognitive scores in children whose blood lead concentration declined most were generally not improved relative to the scores of children whose blood lead levels declined least. Changes in IQ and declines in blood lead levels that occurred between the ages of 7 and 11 to 13 years (r= 0.12, P= .09) suggested slightly better cognition among children whose blood lead levels declined most. CONCLUSION: The cognitive deficits associated with exposure to environmental lead in early childhood appear to be only partially reversed by a subsequent decline in blood lead level.

ABSTRACT

OBJECTIVE: To examine the relationship between parental adjustment and family adjustment during the period after the children's diagnosis of cancer and the psychological adjustment of children 2 years after their diagnosis. METHOD: The study used a prospective design. Children aged 2 to 5 years with cancer and their parents and families (n = 38) were assessed immediately after the children's diagnosis and again 2 years after the diagnosis. Path analysis was used to investigate the relationship between parental and family adjustment during the period after diagnosis and the psychological adjustment of the children 2 years after their diagnosis. RESULTS: Maternal adjustment during the period after the children's cancer was diagnosed had a significant relationship with the children's psychological adjustment 2 years after diagnosis. In contrast, the adjustment of fathers and family adjustment appeared to have a more limited impact on the later psychological adjustment of the children. CONCLUSION: The level of distress experienced by mothers after the children's diagnosis may have an important influence on the later psychological adjustment of the children. It is possible that this is due to the impact of maternal distress on the capacity of mothers to care for their children during the children's treatment for cancer.
