Changes in quality of life among Norwegian school children: a six-month follow-up study

Thomas Jozefiak; Bo Larsson; Lars Wichstrøm

BackgroundA considerable gap exists in regard to longitudinal research on quality of life (QoL) in community populations of children and adolescents. Changes and stability of QoL have been poorly examined, despite the fact that children and adolescents undergo profound developmental changes. The aims of the study were to investigate short-term changes in student QoL with regard to sex and age in a school-based sample.MethodsA representative Norwegian sample of 1,821 school children, aged 8–16 years and their parents were tested at baseline and 6 months later, using the Inventory of Life Quality for Children and Adolescents (ILC) and the Kinder Lebensqualität Fragebogen (KINDL). Student response rate at baseline was 71.2% and attrition over the follow-up period was 4.6%, and 1,336 parents (70%) completed the follow-up. Change scores between baseline and follow-up evaluations were analysed by means of ANCOVA in regard to sex and age effects.ResultsStudents in the 8th grade reported a decrease in QoL over the six-month follow-up period as compared to those in the 6th grade with regard to Family and School domains and total QoL on the KINDL. For emotional well-being a significant linear decrease in QoL across grades 6th to 10th was observed. However, student ratings on the Friends and Self-esteem domains did not change significantly by age. Girls reported a higher decrease in their QoL across all grades over the follow-up period than did boys in respect of Self-esteem on the KINDL, and an age-related decrease in total QoL between 6th and 8th grade on the ILC. Parent reports of changes in child QoL were nonsignificant on most of the domains.ConclusionThe observed age and sex-related changes in school childrens QoL across the six-month follow-up period should be considered in epidemiological as well as clinical research.

Childhood maltreatment is known to increase the risk of future psychiatric disorders. In the present study, we explored the impact of experienced maltreatment on the prevalence and comorbidity of psychiatric disorders in a high-risk population of adolescents in residential care units. We also studied the impact of poly-victimization. The participants of the study were adolescents in residential care units in Norway (n=335, mean age 16.8 years, girls 58.5%). A diagnostic interview (Child and Adolescent Psychiatric Assessment Interview) was used, yielding information about previous maltreatment (witnessing violence, victim of family violence, community violence, sexual abuse) and DSM-IV diagnoses present in the last three months. Exposure to maltreatment was reported by 71%, and in this group, we found significantly more Aspergers syndrome (AS) (p=.041), conduct disorder (CD) (p=.049), major depressive disorder (MDD) (p=.001), dysthymia (p=.030), general anxiety disorder (GAD) (p<.001), and having attempted suicide (p=.006). We found significantly more comorbid disorders in the maltreated group. Poly-victimization was studied by constructing a scale comprised of witnessing violence, victim of family violence, victim of sexual abuse and household dysfunction. We found that poly-victimization was associated with significantly increased risk of MDD, GAD, AS, CD, and having attempted suicide (p<.01). The complexity of the clinical outcomes revealed in this study suggest that longer-term treatment plans and follow-up by psychiatric services might be needed to a greater extend than for the rest of the child and adolescent population, and that trauma informed care is essential for adolescents in residential youth care.

BackgroundDuring the recent decade, a number of studies have begun to address Quality of Life (QoL) in children and adolescents with mental health problems in general population and clinical samples. Only about half of the studies utilized both self and parent proxy report of child QoL. Generally children with mental health problems have reported lower QoL compared to healthy children. The question whether QoL assessment by both self and parent proxy report can identify psychiatric health services needs not detected by an established instrument for assessing mental health problems, i.e. the Child Behavior Checklist (CBCL), has never been examined and was the purpose of the present study.MethodsNo study exists that compares child QoL as rated by both child and parent, in a sample of referred child psychiatric outpatients with a representative sample of students attending public school in the same catchment area while controlling for mental health problems in the child. In the current study patients and students, aged 8-15.5 years, were matched with respect to age, gender and levels of the CBCL Total Problems scores. QoL was assessed by the self- and parent proxy-reports on the Inventory of Life Quality in Children and Adolescents (ILC). QoL scores were analyzed by non-parametric tests, using Wilcoxon paired rank comparisons.ResultsBoth outpatients and their parents reported significantly lower child QoL on the ILC than did students and their parents, when children were matched on sex and age. Given equal levels of emotional and behavioural problems, as reported by the parents on the CBCL, in the two contrasting samples, the outpatients and their parents still reported lower QoL levels than did the students and their parents.ConclusionsChild QoL reported both by child and parent was reduced in outpatients compared to students with equal levels of mental health problems as reported by their parents on the CBCL. This suggests that it should be helpful to add assessment of QoL to achieve a fuller picture of children presenting to mental health services.

Background: Previous studies from Nordic countries suggest that parent ratings of childrens emotional and behavioural problems using the Child Behavior Checklist (CBCL) are among the lowest in the world. However, there has been no Norwegian population study with acceptable response rates to provide valid Norwegian reference data. Aims: Firstly, to compare CBCL Internalizing, Externalizing, Total Problems and Competence scores of Norwegian children and adolescents with those from 1) previous Norwegian studies, 2) other Nordic countries, and 3) international data. Secondly, to present Norwegian reference data in order to perform these comparisons. Thirdly, to investigate the effects of age, gender, socio-economic and urban/rural status on the CBCL. Methods: A stratified cluster sample of 2582 school children (1302 girls and 1280 boys) was identified from the general Norwegian population and their parents were asked to complete the CBCL. Results: The response rate was 65.5%. The mean Total Problems score for the whole sample was 14.2 (standard deviation, s = 14.1). Girls were rated as having greater Competence and fewer Total Problems than boys. Younger children had more Total Problems than adolescents. Parents with low education reported more child Total Problems and lower Competence than those with high education. All effect sizes were small, except for the effect of parental education on child Competence, which was moderate. Conclusions: Total Problems scores were lower than in other societies. The data from this study obtained from one county in central Norway provide an important reference for clinical practice and treatment outcome research.

PURPOSE To explore subjective and proxy reported QoL (Quality of Life) in children and adolescents surviving cancer three years after diagnosis compared with healthy controls. METHOD Case-control study including 50 children and adolescents diagnosed with cancer between January 1, 1993 and January 1, 2003 and treated at the Paediatric Department of St. Olavs University Hospital in Trondheim, Norway. Data were collected using The Inventory of Life Quality in Children and Adolescents (ILC) and the KINDL QoL questionnaires (parent and self-reports), as well as by collecting data for any somatic late effects and psychological problems from the medical records of children surviving cancer. RESULTS Adolescents surviving cancer as a group assessed their QoL as similar to that of their peers. However, adolescents surviving brain tumours or those with late effects reported lower QoL and an increased number of QoL domains perceived as problematic, even many years after diagnosis and treatment. Parents generally report a poorer QoL for their children surviving cancer and a greater number of QoL domains experienced as problematic compared with parent controls. CONCLUSION To improve the childs total functioning and well-being we conclude that when planning long-term follow-up care, rehabilitation of children and adolescents with cancer, especially for survivors with brain tumours, and with late effects should particularly take into account their subjectively perceived and proxy reported QoL, in addition to their psychological problems and psychosocial functioning.

OBJECTIVE: To identify sociodemographic, child, parent, and day care provider factors at age 4 that predict Norwegian children’s service use for mental health problems at age 7. METHOD: Two birth cohorts of 4-year-old children and their parents living in the city of Trondheim, Norway, were invited (82% consented). We successfully interviewed 995 parents among 1250 drawn to participate using the Preschool Age Psychiatric Assessment to set diagnoses and record parental burden and service use. Information concerning sociodemographics, child impairment, parental social support, and child need for mental health services according to parents, day care teacher, and health nurse were obtained. RESULTS: Rate of service use among those with a behavioral or emotional disorder was 10.7% at age 4 and 25.2% at age 7. Behavioral disorders (odds ratio [OR] 2.6, confidence interval [CI] 1.3–5.3), but not emotional disorders, predicted service use. When adjusted for incapacity (OR 1.3, CI 1.2–1.6), disorders were no longer predictive. Incapacity, in turn, was not predictive once parental burden (OR 1.1, CI 1.0–1.1) and parents’ (OR 2.7, CI 1.0–7.9) and day care teachers’ (OR 2.1, CI 1.4–3.2) judgment of child need of help were included. Lower socioeconomic status predicted more service use over and beyond these factors (OR 3.0, CI 1.5–6.1). CONCLUSIONS: Behavioral disorders may instigate service use if they result in impairment, and such impairment may operate via increased parental burden and parent and caregiver problem recognition. Service use may be increased through effective screening programs and efforts to increase day care teachers’ recognition of emotional problems.

Objective: The aim of this study was to assess the impact of self-reported emotional and conduct problems on family functioning and quality of life (QoL) among adolescents with ADHD. Method: The ADHD group (N = 194) was divided into the following groups: without additional emotional or conduct problems, with emotional problems, with conduct problems, and with both problem types. The cross-sectional study included parent and adolescent reports. Results: Adolescents with ADHD and both problem types reported significantly lower QoL and family functioning than all other ADHD groups. Parents reported better QoL for the ADHD group without additional problems, but similar family functioning for all groups. Conclusion: A higher level of coexisting psychiatric problems had a significant impact on adolescents’ reports of family functioning and QoL. However, coexisting problems showed no association with parent reports of family functioning. Adolescents with ADHD might add important information in clinical assessment.

BackgroundSymptoms of anxiety and depression are significantly associated in parents and children, but few studies have examined associations between recurrent parental problems and offspring symptoms, and fathers have rarely been included in these studies. Additionally, few have investigated factors that may protect against familial aggregation of anxiety and depression. The aims of the present study are to examine the associations between recurrent parental anxiety/depression over a ten-year time span and offspring anxiety/depression in adolescence and to test whether two factors proposed to be inversely related to anxiety and depression, namely, adolescent self-esteem and physical activity, may moderate and mediate the transmission of anxiety/depression.MethodsThis study used data from two waves of a Norwegian community study (the HUNT study) consisting of 5,732 adolescents, ages 13–18, (mean age = 15.8, 50.3% girls) who had one (N = 1,761 mothers; N = 742 fathers) or both parents (N = 3,229) participating in the second wave. In the first wave, 78% of the parents also participated. The adolescents completed self-reported questionnaires on self-esteem, physical activity, and symptoms of anxiety/depression, whereas parents reported on their own anxiety/depressive symptoms. The data were analysed with structural equation modeling.ResultsThe presence of parental anxiety/depression when offspring were of a preschool age predicted offspring anxiety/depression when they reached adolescence, but these associations were entirely mediated by current parental symptoms. Self-esteem partly mediated the associations between anxiety/depression in parents and offspring. No sex differences were found. Physical activity moderated the direct associations between anxiety/depression in mothers and offspring, whereas no moderating effect was evident with regard to paternal anxiety/depression.ConclusionsThese findings suggest that children of parents with anxiety/depression problems are at a sustained risk for mental health problems due to the apparent 10-year stability of both maternal and paternal anxiety/depression. Thus, preventing familial aggregation of these problems as early as possible seems vital. The associations between parental and offspring anxiety/depression were partially mediated by offspring self-esteem and were moderated by physical activity. Hence, prevention and treatment efforts could be aimed at increasing self-esteem and encouraging physical activity in vulnerable children of parents with anxiety/depression.

Improved quality of life among adolescents with attention-deficit/hyperactivity disorder is mediated by protective factors: a cross sectional survey

Jorun Schei; Torunn Stene Nøvik; Per Hove Thomsen; Marit S. Indredavik; Thomas Jozefiak

BackgroundThe aim of this study was to assess the role of protective factors as mediators and/or moderators of the relationship between coexisting emotional and conduct problems and quality of life (QoL) among adolescents with attention-deficit/hyperactivity disorder (ADHD).MethodsThe sample consisted of 194 adolescents with ADHD. Participants completed measures of individual competencies, family cohesion and social support, and QoL. Coexisting emotional and conduct problems were assessed using the Strength and Difficulties Questionnaire.ResultsIndividual competencies and social support mediated the association between emotional and conduct problems and QoL. Family cohesion was associated with both emotional and conduct problems. No moderating effects of protective factors and coexisting problems were found.ConclusionsThe assessment of individual competencies, social resources, and family cohesion may identify potential treatment goals for adolescents with ADHD and coexisting problems, and may contribute to improvements in QoL.

A comparison between child psychiatric outpatients with AD/HD and anxiety/depression

Christian Thaulow; Thomas Jozefiak

Background: Studies have shown that children with attention-deficit/hyperactivity disorder (AD/HD) have a lower quality of life (QoL), and lower school and psychosocial functioning than healthy children. Aims: This is the first study to compare these domains and child competence between children with AD/HD- and anxiety/depression-related problems and healthy children using data from multiple informants. Method: Children were matched by age and sex, resulting in two clinical groups consisting of 62 children with AD/HD-related problems, 49 children with anxiety/depression-related problems and a reference group of 65 healthy schoolchildren. The Inventory of Life Quality for Children and Adolescents (parent and child report), the Child Behaviour Checklist (parent report), the Teachers Report Form and the Childrens Global Assessment Scale (therapist evaluation) were used. Differences between group means were analysed by t-tests and analysis of variance. Results: The AD/HD group reported a significantly higher QoL than did the Anxiety/Depression group. However, no significant differences in QoL were found between the two clinical groups by parent proxy report. The AD/HD group reported a significantly higher QoL than shown by parent proxy evaluation. According to parent and teacher reports, both clinical groups showed significantly lower school functioning than the group of healthy children. Further, the AD/HD group showed significantly lower school functioning and total competence than the Anxiety/Depression group. Conclusion: To obtain a full clinical picture of subgroups of patients with AD/HD- and anxiety/depression-related problems referred to child mental health outpatient treatment, clinicians should always use multiple informants to evaluate symptoms/problems, functioning and QoL.
