Reliability and validity of the adolescent health profile-types

Pilot evaluation of a school-based health education intervention in the UK: Facts4Life

Background

This study assessed short-term changes in children's health and illness attitudes and health status following Facts4Life, a school-based health education intervention.

Methods

Children aged 7-11 years (School Years 3-6) recruited from 10 schools in the UK participated in this study. A quasi-experimental design was utilized with 187 children participating in the intervention, and 108 forming a control condition. Children in both conditions completed measures of health and illness attitudes and health status at baseline and at immediate follow-up. Intervention effects were examined using mixed between-within subjects analysis of variance.

Results

Analysis revealed significant baseline to follow-up improvements in intervention group responses to 'When I feel unwell I need to take medicine to feel better' (Years 3 and 4: P = 0.05, η2p = 0.02; Years 5 and 6: P = 0.004, η2p = 0.07). For intervention group children in Years 5 and 6 there was an improvement in response to 'When I am ill, I always need to see a doctor' (P = 0.01, η2p = 0.07). There was no evidence that Facts4Life had an impact upon health status.

Conclusions

This study identified some positive intervention effects and results suggest that Facts4Life has potential as a school-based health education intervention.

Factors associated with physical activity among adolescent and young adult survivors of early childhood cancer: A report from the childhood cancer survivor study (CCSS)

OBJECTIVE

To evaluate concurrent and longitudinal associations between psychosocial functioning and physical activity in adolescent and young adult survivors of early childhood cancer.

METHODS

Adolescent survivors of early childhood cancer (diagnosed before age four) participating in the Childhood Cancer Survivor Study completed the Coping Health and Illness Profile-Adolescent Edition (CHIP-AE; n = 303; mean age at survey: 17.6 years). A subset of these survivors (n = 248) completed a follow-up survey an average of 6.0 years later (range: 4-10). Logistic regression identified associations between psychosocial functioning in adolescence and physical activity levels in adolescence and young adulthood.

RESULTS

Survivors reported low physical activity as adolescents (46.1% scored below CHIP-AE cut-point) and young adults (40.8% below Centers for Disease Control guidelines). Poor physical activity during adolescence was associated with female sex (OR = 2.06, 95% CI, 1.18-3.68), parents with less than a college education (OR = 1.91, 95% CI, 1.11-3.32), previous treatment with cranial radiation (OR = 3.35, 95% CI, 1.69-6.88), TV time (OR = 1.77, 95% CI, 1.00-3.14), and limitations of activity due to health or mobility restrictions (OR = 8.28, 95% CI, 2.87-30.34). Poor diet (OR = 1.84, 95% CI, 1.05-3.26) and low self-esteem (OR = 1.80, 95% CI, 0.99-3.31) during adolescence were associated with lower odds of meeting Centers for Disease Control physical activity guidelines in young adulthood.

CONCLUSION

These findings provide targets for future interventional studies to improve physical activity in this high-risk population.

The Relationship Between the Use of Health Clinics in Rural Mississippi Schools and the CHIP-AE Adolescent Health Profile

School health clinics are one way to meet the objectives in Healthy People 2010 for adolescent health. To determine the relationship between adolescent health status and use of the school health clinics in four Mississippi high schools, the Child Health and Illness Profile–Adolescent Edition (CHIP-AE) was used. The CHIP-AE identifies health status, giving scores on resilience, comfort, risks, and satisfaction, resulting in health profiles. One hundred seventy-one 9th-graders participated in this descriptive study. Students with the highest discomfort and risk scores had no use of the school health clinic. Students with fair health profiles were the highest users of the school health clinic when compared to all other profiles. Of those students with very poor health status, 60% reported the school health clinic was their only source of health care. In this study, the term school health clinic refers to the health office staffed by a nurse without an advanced degree.

How to assess quality of life in child and adolescent psychiatry

This article provides an overview of the conceptual foundations of measuring health-related quality of life (HRQoL) in children and adolescents in child and adolescent psychiatry, and of the current state of research in this field. The available procedures for determining quality of life are presented according to their areas of use and their psychometric characteristics. The internationally available generic instruments for measuring HRQoL in children are identified and assessed in terms of their strengths and weaknesses with regard to selected criteria. As a result, seven generic HRQoL instruments and two utility procedures have been identified which satísfy the following criteria: (i) psychometric qualíty; (ii) age-appropriate measurement; (iii) versions for self-reporting and external rating; and (iv) cross-cultural measurement. The identified instruments satisfy the individual criteria to different degrees. They are increasingly being used in health services research, treatment studies, and epidemiological research; however, they are not yet widely used as part of the clinical routine in child and adolescent psychiatrics.

A systematic review of generic multidimensional patient-reported outcome measures for children, part II: evaluation of psychometric performance of English-language versions in a general population

OBJECTIVES

The objectives of this systematic review were 1) to identify studies that assess the psychometric performance of the English-language version of 35 generic multidimensional patient-reported outcome measures (PROMs) for children and young people in general populations and evaluate their quality and 2) to summarize the psychometric properties of each PROM.

METHODS

MEDLINE, EMBASE, and PsycINFO were searched. The methodological quality of the articles was assessed using the COnsensus-based Standards for selection of health Measurement INstruments checklist. For each PROM, extracted evidence of content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision was judged against standardized reference criteria.

RESULTS

We found no evidence for 14 PROMs. For the remaining 21 PROMs, 90 studies were identified. The methodological quality of most studies was fair. Quality was generally rated higher in more recent studies. Not reporting how missing data were handled was the most common reason for downgrading the quality. None of the 21 PROMs has had all psychometric properties evaluated; data on construct validity and internal consistency were most frequently reported.

CONCLUSIONS

Overall, consistent positive findings for at least five psychometric properties were found for Child Health and Illness Profile, Healthy Pathways, KIDSCREEN, and Multi-dimensional Student Life Satisfaction Scale. None of the PROMs had been evaluated for responsiveness to detect change in general populations. Further well-designed studies with transparent reporting of methods and results are required.

A systematic review of generic multidimensional patient-reported outcome measures for children, part I: descriptive characteristics

OBJECTIVES

To identify generic, multidimensional patient-reported outcome measures (PROMs) for children up to 18 years old and describe their characteristics and content assessed using the International Classification of Functioning, Disability and Health Children and Youth version (ICF-CY).

METHODS

The search strategy, developed by an information specialist, included four groups of terms related to "measure," "health," "children and young people," and "psychometric performance." The search was limited to publications from 1992. Five electronic databases and two online-specific PROM databases were searched. Two groups of reviewers independently screened all abstracts for eligible PROMs. Descriptive characteristics of the eligible PROMs were collected, and items and domains of each questionnaire were mapped onto the ICF-CY chapters.

RESULTS

We identified 35 PROMs, of which 29 were generic PROMs and 6 were preference-based measures. Many PROMs cover a range of aspects of health; however, social functioning is represented most often. Content covered differs both in which aspects of health are assessed and whether individual questions focus on functioning (what the subject can or does do) and/or well-being (how the subject feels about a certain aspect of his or her health).

CONCLUSIONS

A broad variety of PROMs is available to assess children's health. Nevertheless, only a few PROMs can be used across all age ranges to 18 years. When mapping their content on the ICF-CY, it seems that most PROMs exclude at least one major domain, and all conflate aspects of functioning and well-being in the scales.

Informing the NHS Outcomes Framework: evaluating meaningful health outcomes for children with neurodisability using multiple methods including systematic review, qualitative research, Delphi survey and consensus meeting

Background

The identification of suitable outcome measures will improve the evaluation of integrated NHS care for the large number of children affected by neurodisability, and has the potential to encourage the provision of more appropriate and effective health care. This research sought to appraise the potential of patient-reported outcome measures (PROMs) for children and young people with neurodisability.

Aim

This research aimed (i) to identify key outcomes of health care for children with neurodisability, beyond morbidity and mortality, from the perspectives of children, parents and professionals; (ii) to critically appraise existing generic multidimensional PROMs; and (iii) to examine whether or not the key outcomes might be measured by existing PROMs. We also sought agreement on a definition of neurodisability.

Methods

Data were gathered in three main ways, (i) a systematic review identified eligible generic multidimensional PROMs and peer-reviewed studies evaluating psychometric performance using English-language questionnaires. Studies were appraised for methodological quality and psychometric performance was appraised using standard criteria. (ii) Focus groups and interviews with children and young people with neurodisability, and separately with parents, sought to identify important outcomes of NHS care, and their feedback on example PROM questionnaires. (iii) An online Delphi survey was conducted with a multidisciplinary sample of health professionals to seek agreement on appropriate NHS outcomes. In addition, we convened a consensus meeting with a small nominal group of young people, parents and professionals; the group sought agreement on a core set of important health outcomes.

Results

From the systematic review, we identified 126 papers that reported eligible evidence regarding the psychometric performance of 25 PROMs. Evidence of psychometric robustness was more favourable for a small number of PROMs: KIDSCREEN (generic), DISABKIDS (chronic-generic) and Child Health Utility 9D (preference-based measure). The Pediatric Quality of Life Inventory and KINDL offer both self-report and a proxy report version for a range of age bands, but evidence of their psychometric performance was weaker. Evidence was lacking in one or more respects for all candidate PROMs, in both general populations and those with neurodisability. Proxy reporting was found generally to be poorly correlated with self-report. Focus groups and interviews included 54 children and young people, and 53 parents. The more important health outcomes were felt to be communication, emotional well-being, pain, mobility, independence/self-care, worry/mental health, social activities and sleep. In addition, parents of children with intellectual impairment identified behaviour, toileting and safety as important outcomes. Participants suggested problems with the face validity of example PROM questionnaires for measuring NHS care. In the Delphi survey, 276 clinicians from a wide range of professions contributed to at least one of four rounds. Professionals rated pain, hearing, seeing, sleep, toileting, mobility and communication as key goals for the NHS but also identified treating neurological symptoms as important. Professionals in the Delphi survey and parents working with the research team agreed a proposed definition for neurodisability. The consensus meeting confirmed overlap between the outcomes identified as important by young people, parents and professionals, but not complete agreement.

Conclusions

There was agreement between young people, parents and professionals regarding a core suite of more important health outcomes: communication, emotional well-being, pain, mobility, independence/self-care, worry/mental health, social activities and sleep. In addition, behaviour, toileting and safety were identified as important by parents. This research suggests that it would be appropriate to measure these constructs using PROMs to assess health care. None of the candidate PROMs in the review adequately captures all of the identified constructs, and there is inadequate evidence that candidate PROMs are psychometrically robust for use across children with neurodisability. Further consultation with young people, families and professionals is warranted to support the use of PROMs to measure NHS outcomes. Research to test potential PROMs with different age groups and conditions would be valuable.

Long-term quality-of-life and functioning comparison of atomoxetine versus other standard treatment in pediatric attention-deficit/hyperactivity disorder

Psychopharmacological agents were shown to be important for improving the quality of life (QoL) of patients with attention-deficit/hyperactivity disorder (ADHD). A short-term, 10-week study found atomoxetine (ATX) to be effective in improving QoL of ADHD patients. We compared, for the first time, long-term treatment outcomes of ATX and other early standard therapy (OEST, any pharmacological ADHD treatment except ATX) in QoL and functional impairment in pharmacologically naive children/ adolescents in a randomized, controlled, open-label study at 6 and 12 months. Patients received ATX (0.5-1.8 mg/kg per day) or OEST (mainly methylphenidate). Quality of life and functioning were assessed by the Child Health and Illness Profile-Child Edition, Parent Rating Form and the Weiss Functional Impairment Rating Scale-Parent Report. Three hundred ninety-eight patients (79.4% male; mean age, 9.3 years) received study treatment. The Child Health and Illness Profile-Child Edition, Parent Rating Form achievement domain t scores significantly improved from baseline to 6 months from means of 28.0 to 37.1 for ATX and from 28.3 to 40.7 for OEST. Mean t scores at 12 months were 40.0 for ATX and 41.0 for OEST. The Weiss Functional Impairment Rating Scale-Parent Report total score improved from baseline to 6 months in both groups (ATX: mean 1.02 to 0.63; OEST: 0.96 to 0.59). Both treatments were safe with no statistically significant difference in the overall rate of adverse events. Overall, the improvements in QoL and functional impairment observed over time for ATX and OEST were meaningful and stable over the study period of 12 months. Between-group differences were small but sometimes statistically significant, providing the first-time long-term comparative symptomatic and QoL analysis between ATX and OEST.

Symptoms and quality of life indicators among children with chronic medical conditions

BACKGROUND

Children with chronic conditions often experience numerous symptoms, but few research studies examine patterns of symptoms and quality of life (QoL) indicators.

OBJECTIVE

To examine if reliable latent classes of children with chronic medical conditions can be identified based on the clustering of symptoms and QoL indicators.

METHODS

Structured interviews were conducted with children ages 9-21 living with chronic medical conditions (N = 90). Multiple symptoms (e.g., pain, sleep, fatigue, and depression) and QoL indicators (e.g., life satisfaction and social support) were measured. Physical health and emotional, social, and school functioning were measured using the Pediatric Quality of Life Inventory (PedsQL). Latent class analysis was used to classify each child into a latent class whose members report similar patterns of responses.

RESULTS

A three-class solution had the best model fit. Class 1 (high-symptom group; n = 15, 16.7%) reported the most problems with symptoms and the lowest scores on the QoL indicators. Class 2 (moderate-symptom group; n = 39, 43.3%) reported moderate levels of both symptoms and QoL indicators. Class 3 (low-symptom group; n = 36, 40.0%) reported the lowest levels of symptoms and the highest scores on the QoL indicators.

CONCLUSIONS

The three latent classes identified in this study were distributed along the severity continuum. All symptoms and QoL indicators appeared to move in the same direction (e.g., worse symptoms with lower QoL). The PedsQL psychosocial health summary score (combining emotional, social, and school functioning scores) discriminated well between children with different levels of disease burden.

Health and well-being in adolescent survivors of early childhood cancer: a report from the Childhood Cancer Survivor Study

OBJECTIVE

With the growing number of childhood cancer survivors in the US, it is important to assess the well-being of these individuals, particularly during the transitional phase of adolescence. Data about adolescent survivors' overall health and quality of life will help identify survivor subgroups most in need of targeted attention to successfully transition to adulthood.

PARTICIPANTS AND METHODS

This ancillary study to the Childhood Cancer Survivor Study focused on children 15-19 years of age who had been diagnosed with cancer before the age of 4 years. A cohort of siblings of pediatric cancer survivors of the same ages served as a comparison sample. Adolescent health was assessed using the Child Health and Illness Profile-Adolescent Edition (CHIP-AE) survey.

RESULTS

The teen survey was sent to 444 survivor teens and 189 siblings. Of these, 307(69%) survivors and 97 (51%) siblings completed and returned the survey. The overall health profiles of siblings and survivors were similar. Among survivors, females scored significantly below males on satisfaction, discomfort, and disorders domains. Survivors diagnosed with central nervous system tumors scored less favorably than leukemia survivors in the global domains of satisfaction and disorders.

CONCLUSION

In general, adolescent survivors fare favorably compared to healthy siblings. However, identification of the subset of pediatric cancer survivors who are more vulnerable to medical and psychosocial disorders in adolescence provides the opportunity for design and implementation of intervention strategies that may improve quality of life.

Gender Differences in Predictors of Self-Reported Physical Aggression: Exploring Theoretically Relevant Dimensions among Adolescents from Santiago, Chile

Research findings remain unclear on whether different factors predict aggression for adolescent men and women. Given that aggression research is rarely conducted with Latin American populations, the current study used multiple imputation and linear regression to assess gender differences in levels and predictors of self-reported physical aggression among a community sample of young (ages 11 through 17) men (n=504) and women (n = 471) from Santiago, Chile. Results revealed that adolescent women reported engaging in higher levels of physical aggression than men. The variables found to be significantly associated with higher levels of reported aggression-younger age, less family involvement, less parental control, less positive relationships with caregivers, having more friends who act out and use substances, having fewer friends committed to learning, presence of dating violence, and more exposure to neighborhood crime-were not moderated by gender, implying that similar factors are related to aggression in adolescent men and women from Chile. Implications for prevention and intervention efforts to address high-risk adolescents and reduce aggression among Chilean youth are discussed.

Examining the Quality of Adolescent-Parent Relationships Among Chilean Families

The purpose of this study was to examine if adolescents reports of warm and harsh parenting practices by their mothers and fathers varied as a function of demographic, youth and their mothers or mother figures' individual and family characteristics. Data are from 707 community-dwelling adolescents (mean age=14, SD=1.4) and their mothers or mother figures in Santiago, Chile. Having a warmer relationship with both parents was inversely associated with the adolescents' age and positively associated with adolescents' family involvement and parental monitoring. Both mothers' and fathers' harsh parenting were positively associated with adolescent externalizing behaviors and being male and inversely associated with youth autonomy and family involvement. These findings suggest that net of adolescent developmental emancipation and adolescent behavioral problems, positive relationships with parents, especially fathers, may be nurtured through parental monitoring and creation of an interactive family environment, and can help to foster positive developmental outcomes.

Health profiles of adolescents in foster care

The purpose of this paper is to describe health profiles of adolescents in foster care. The Child Health and Illness Profile-Adolescent Edition clustered adolescents in foster care into 13 mutually exclusive health profiles using dimensions of satisfaction with health, risks, resilience, and discomfort. Health profiles were further characterized into four health status rankings from best to worst health status. Many reported best health status (39%); nearly equal numbers (30.6%) had profiles indicating poor or worst health status, particularly girls and those with high risk behaviors, aggression, sexual abuse, or suicidality. It is valuable to identify health characteristics of the most vulnerable subgroups of foster youth to tailor specific interventions.

ACHESS--The Australian study of child health in same-sex families: background research, design and methodology

Background

There are an increasing number of children in Australia growing up with same-sex attracted parents. Although children from same-sex parent families do in general perform well on many psychosocial measures recent research is beginning to consider some small but significant differences when these children are compared with children from other family backgrounds. In particular studies suggest that there is an association between the stigma that same-sex parent families experience and child wellbeing. Research to date lacks a holistic view with the complete physical, mental and social wellbeing of children not yet addressed. In addition, most studies have focused only on families with lesbian parents and have studied only small numbers of children.

Methods/design

The Australian Study of Child Health in Same-Sex Families (ACHESS) is a national study that aims to determine the complete physical, mental and social wellbeing of Australian children under the age 18 years with at least one parent who self identifies as being same-sex attracted. There will be a particular focus on the impact that stigma and discrimination has on these families. Parent and child surveys will be used to collect data and will be available both online and in paper form. Measures have been chosen whenever possible that have sound conceptual underpinnings, robust psychometric properties and Australian normative data, and include the Child Health Questionnaire (CHQ), the Strengths and Difficulties Questionnaire (SDQ) and the Kessler Psychological Distress Scale (K10).

Discussion

ACHESS aims to be the largest study of its kind and will for the first time produce a detailed quantitative analysis of Australian children with same-sex attracted parents. By inviting participants to take part in further research it will also establish a valuable cohort of children, and their families, to launch future waves of research that will help us better understand the health and wellbeing of children with same-sex attracted parents.

Autism spectrum disorders: a review of measures for clinical, health services and cost-effectiveness applications

Autism spectrum disorders (ASDs) are characterized by impairments in social interaction, communication and behavioral functioning that can affect the health-related quality-of-life outcomes of the affected child and the family. ASDs have increased in prevalence, leading to a demand for improved understanding of the comparative effectiveness of different pharmacologic, behavioral, medical and alternative treatments for children as well as systems for providing services. This review describes outcome instruments that can be used for clinical, health services and cost-effectiveness applications. There is a pressing need to identify the most appropriate instruments for measuring health-related quality-of-life outcomes in this population. Studies evaluating the cost-effectiveness of interventions or treatments for children with ASDs using the cost per quality-adjusted life year metric are lacking. Researchers have the potential to contribute greatly to the field of autism by quantifying outcomes that can inform optimal treatment strategies.

Corporal punishment and youth externalizing behavior in Santiago, Chile

OBJECTIVES

Corporal punishment is still widely practiced around the globe, despite the large body of child development research that substantiates its short- and long-term consequences. Within this context, this paper examined the relationship between parental use of corporal punishment and youth externalizing behavior with a Chilean sample to add to the growing empirical evidence concerning the potential relationship between increased corporal punishment and undesirable youth outcomes across cultures.

METHODS

Analysis was based on 919 adolescents in Santiago, Chile. Descriptive and multivariate analyses were conducted to examine the extent to which parents' use of corporal punishment and positive family measures were associated with youth externalizing behavior. Furthermore, the associations between self-reported externalizing behavior and infrequent, as well as frequent, use of corporal punishment were investigated to understand how varying levels of parental use of corporal punishment were differently related to youth outcomes.

RESULTS

Both mothers' and fathers' use of corporal punishment were associated with greater youth externalizing behavior. Additionally, increases in positive parenting practices, such as parental warmth and family involvement, were met with decreases in youth externalizing behavior when controlling for youth demographics, family socioeconomic status, and parents' use of corporal punishment. Finally, both infrequent and frequent use of corporal punishment were positively associated with higher youth problem behaviors, though frequent corporal punishment had a stronger relationship with externalizing behavior than did infrequent corporal punishment.

CONCLUSIONS

Parental use of corporal punishment, even on an occasional basis, is associated with greater externalizing behavior for youth while a warm and involving family environment may protect youth from serious problem behaviors. Therefore, findings of this study add to the growing evidence concerning the negative consequences of corporal punishment for youth outcomes.

The Association of Family and Peer Factors with Tobacco, Alcohol, and Marijuana Use Among Chilean adolescents in Neighborhood Context

Research on adolescent use of substances has long sought to understand the family factors that may be associated with use of different substances such as alcohol, tobacco, and marijuana. However, scant attention has been focused on these questions in Latin American contexts, despite growing concerns about substance use among Latin American youth. Using data from a sample of 866 Chilean youth, we examined the relationship of family and neighborhood factors with youth substance abuse. We found that in a Latin American context, access to substances is an important predictor of use, but that neighborhood effects differ for marijuana use as opposed to cigarettes or alcohol. Age of youth, family and peer relationships, and gender all play significant roles in substance use. The study findings provide additional evidence that the use of substances is complex, whereby individual, family, and community influences must be considered jointly to prevent or reduce substance use among adolescents.

Family and parenting characteristics associated with marijuana use by Chilean adolescents

OBJECTIVE: Family involvement and several characteristics of parenting have been suggested to be protective factors for adolescent substance use. Some parenting behaviors may have stronger relationships with adolescent behavior while others may have associations with undesirable behavior among youth. Although it is generally acknowledged that families play an important role in the lives of Chilean adolescents, scant research exists on how different family and parenting factors may be associated with marijuana use and related problems in this population which has one of the highest rates of drug use in Latin America. METHODS: Using logistic regression and negative binomial regression, we examined whether a large number of family and parenting variables were associated with the possibility of Chilean adolescents ever using marijuana, and with marijuana-related problems. Analyses controlled for a number of demographic and peer-related variables. RESULTS: Controlling for other parenting and family variables, adolescent reports of parental marijuana use showed a significant and positive association with adolescent marijuana use. The multivariate models also revealed that harsh parenting by fathers was the only family variable associated with the number of marijuana-related problems youth experienced. CONCLUSION: Of all the family and parenting variables studied, perceptions of parental use of marijuana and harsh parenting by fathers were predictors for marijuana use, and the experience of marijuana-related problems. Prevention interventions need to continue emphasizing the critical socializing role that parental behavior plays in their children's development and potential use of marijuana.

Sexual intercourse among adolescents in Santiago, Chile: a study of individual and parenting factors

OBJECTIVE

to examine a range of individual, parenting, and family factors associated with sexual intercourse among a community sample of youth and their families in Santiago, Chile.

METHODS

Data were taken from the Santiago Longitudinal Study conducted in January 2008-November 2009. Participants were 766 youth (mean age = 14.03 years, 51% male) from municipalities of low- to mid-socioeconomic status. Variables included emotional and behavioral subscales from the Child Behavior Checklist's Youth Self Report, parental monitoring, family involvement, parental control and autonomy, relationship with each parent, and sexual activity. Bivariate and multivariate logistic regression models were used to examine the odds of sexual intercourse initiation.

RESULTS

seventy (9.14%) youth reported having had sex in their lifetime; the average age of first sexual intercourse among this group was 13.5 years (Standard Deviation [SD] = 1.74) for males and 14.08 (SD = 1.40) for females. Having sex was inversely associated with withdrawn-depressed symptoms (Odds Ratio [OR] = 0.84, Confidence Interval [CI] = 0.72-0.97), but positively associated with somatic complaints (OR = 1.20, CI = 1.04-1.38) and rule breaking behavior (OR = 1.21, CI = 1.08-1.36), after adjusting for demographic and other individual and parenting variables. The majority (80%) of the youth who had had sex reported using protection at the time of last intercourse.

CONCLUSIONS

findings highlight the role that mental health problems-some of them not commonly associated with onset of sexual activity-may play in a youth's decision to have sex. The potential protective effects of several parenting and family characteristics disappeared with youth age and youth behavioral problems.

Reliability and validity of the Spanish version of the Child Health and Illness Profile (CHIP) Child-Edition, Parent Report Form (CHIP-CE/PRF)

BACKGROUND

The objectives of the study were to assess the reliability, and the content, construct, and convergent validity of the Spanish version of the CHIP-CE/PRF, to analyze parent-child agreement, and compare the results with those of the original U.S. version.

METHODS

Parents from a representative sample of children aged 6-12 years were selected from 9 primary schools in Barcelona. Test-retest reliability was assessed in a convenience subsample of parents from 2 schools. Parents completed the Spanish version of the CHIP-CE/PRF. The Achenbach Child Behavioural Checklist (CBCL) was administered to a convenience subsample.

RESULTS

The overall response rate was 67% (n = 871). There was no floor effect. A ceiling effect was found in 4 subdomains. Reliability was acceptable at the domain level (internal consistency = 0.68-0.86; test-retest intraclass correlation coefficients = 0.69-0.85). Younger girls had better scores on Satisfaction and Achievement than older girls. Comfort domain score was lower (worse) in children with a probable mental health problem, with high effect size (ES = 1.45). The level of parent-child agreement was low (0.22-0.37).

CONCLUSIONS

The results of this study suggest that the parent version of the Spanish CHIP-CE has acceptable psychometric properties although further research is needed to check reliability at sub-domain level. The CHIP-CE parent report form provides a comprehensive, psychometrically sound measure of health for Spanish children 6 to 12 years old. It can be a complementary perspective to the self-reported measure or an alternative when the child is unable to complete the questionnaire. In general, the results are similar to the original U.S. version.

Atomoxetine hydrochloride in the treatment of children and adolescents with attention-deficit/hyperactivity disorder and comorbid oppositional defiant disorder: A placebo-controlled Italian study

OBJECTIVE

The primary aim of this study was to assess the efficacy of atomoxetine in improving ADHD and ODD symptoms in paediatric patients with ADHD and comorbid oppositional defiant disorder (ODD), non-responders to previous psychological intervention with parent support.

METHODS

This was a multicentre, randomised, placebo-controlled trial conducted in patients aged 6-15 years, with ADHD and ODD diagnosed according to the DSM-IV criteria by a structured clinical interview (K-SADS-PL). Only subjects who are non-responders to a 6-week standardized parent training were randomised to atomoxetine (up to 1.2 mg/kg/day) or placebo (in a 3:1 ratio) for the following 8-week double blind phase.

RESULTS

Only 2 of the 156 patients enrolled for the parent support phase (92.9% of males; mean age: 9.9 years), improved after the parent training program; 139 patients were randomised for entering in the study and 137 were eligible for efficacy analysis. At the end of the randomised double blind phase, the mean changes in the Swanson, Nolan and Pelham Rating Scale-Revised (SNAP-IV) ADHD subscale were -8.1+/-9.2 and -2.0+/-4.7, respectively in the atomoxetine and in the placebo group (p<0.001 between groups); changes in the ODD subscale were -2.7+/-4.1 and -0.3+/-2.6, respectively in the two groups (p=0.001 between groups). The CGI-ADHD-S score decreased in the atomoxetine group (median change at endpoint: -1.0) compared to no changes in the placebo group (p<0.001 between groups). Statistically significant differences between groups, in favour of atomoxetine, were found in the CHIP-CE scores for risk avoidance domain, emotional comfort and individual risk avoidance subdomains. An improvement in all the subscales of Conners Parents (CPRS-R:S) and Teacher (CTRS-R:S) subscales was observed with atomoxetine, except in the cognitive problems subscale in the CTRS-R:S. Only 3 patients treated with atomoxetine discontinued the study due to adverse events. No clinically significant changes of body weight, height and vital signs were observed in both groups.

CONCLUSIONS

Treatment with atomoxetine of children and adolescents with ADHD and ODD, who did not initially respond to parental support, was associated with improvements in symptoms of ADHD and ODD, and general health status. Atomoxetine was well tolerated.

Quality of life of adolescents with end-stage renal disease and kidney transplant

The health-related quality of life (HRQOL) of adolescents with end-stage renal disease (ESRD) is an important marker of disease burden. Our aims were to investigate HRQOL in a group of children and adolescents with ESRD and to compare them with the reference population norms. Ours was a cross-sectional study of 81 patients aged 10 years to 21 years with ESRD (68 with kidney transplants and 13 on dialysis) at five Spanish paediatric nephrology centres. HRQOL was investigated with the Spanish version of the child health and illness profile, adolescent edition (CHIP-AE). Clinical variables such as underlying diagnosis, number of rejection episodes, pre-emptive transplantation, anaemia and height were also analysed. No differences were found between patients with kidney transplants and their healthy peers in any domain or sub-domain of CHIP-AE. The group on dialysis scored lower than healthy controls and patients with transplants for satisfaction with health. Discomfort was higher in patients with transplants who had suffered one rejection episode. Physical discomfort was increased in anaemic patients with transplants. Short patients scored less in the satisfaction domain, with lower self-esteem and lower satisfaction with health. Adolescents with kidney transplants had better satisfaction with health than the group on dialysis, which matched the level of a healthy population. Further long-term prospective research is warranted.

Health risk behavior of youth in foster care

PROBLEM

Many adolescent health problems are predominantly caused by risk behavior. Foster adolescents have disproportionately poor health; therefore, identification of risk behavior is critical.

METHOD

Data from a larger study were analyzed to investigate the health risk behavior of 56 youth in foster care using the Child Health and Illness Profile-Adolescent Edition.

FINDINGS

Data indicated that youth in foster care had some increased risk behavior when compared with a normative adolescent population. Younger adolescents and those in relative placement had less risky behavior. Risk behavior was increased for youth in foster care when they were in group homes, had experienced a parental death, or had a history of physical or emotional abuse or attempted suicide.

CONCLUSIONS

These results point to areas of strength and vulnerability for youth in foster care and suggest areas for clinicians and caregivers of these adolescents to focus interventions towards harm reduction and enhancement of resiliency.

Population norms and cut-off-points for suboptimal health related quality of life in two generic measures for adolescents: the Spanish VSP-A and KINDL-R

Background

Health-related quality of life (HRQL) outcome measures are complex and for further application in clinical practice and health service research the meaning of their scorings should be studied in depth. The aim of this study was to increase the interpretability of the Spanish VSP-A and KINDL-R scores.

Methods

A representative sample of adolescents aged 12 to 18 years old was selected in Spain. The Spanish VSP-A and KINDL-R, two generic HRQL measures (range: 0–100), were self-administered along with other external anchor measures (Strengths and Difficulties Questionnaire, Oslo Social Support Scale and self-declaration of chronic conditions) and sent by post. Percentiles of both HRQL questionnaires were obtained by gender, and age group and effect sizes (ES) were calculated. Receiver Operating Characteristic curves and related sensitivity (SE) and specificity (SP) values were also computed.

Results

The Spanish VSP-A and KINDL-R were completed by 555 adolescents. A moderate ES was shown in Psychological well-being between younger and older girls (ES: 0.77) in the VSP-A and small ES in the KINDL (ES: 0.41) between these groups. A SE and SP value close to 0.70 was associated to a global HRQL score of 65 in the VSP-A and 70 in the KINDL-R, when compared to anchors measuring mental and psychosocial health. Adolescents with scores bellow these cut-off points showed a moderate probability of presenting more impairment in their HRQL.

Conclusion

The results of this study will be of help to interpret the VSP-A AND KINDL-R questionnaires by comparing with the general population and also provide cut-off points to define adolescents with health problems.

Dimensions of health in young people in foster care

To describe the dimensions of health and illness from the perspective of adolescents in foster care.

METHODS

Descriptive analyses of dimensions of health were conducted on N = 105 adolescents in foster care. Differences among demographic (age, gender, race/ethnicity) and foster care placement (age at first placement, reason(s) for foster care placement, length of time in care, number, and types of placement) variables and the dimensions and subdimensions of health (Child Health and Illness Profile- Adolescent Edition) were determined using T-tests and ANOVA.

RESULTS

Most were placed in long-term foster care (x = 6.46 years; SD = 4.86) during adolescence (38%), with multiple placements (x = 3.99; SD = 3.8). All domains of health were self-reported to be average to low average, with poorer findings in specific risk and resilience subdomains. There were no significant differences by age or race/ethnicity. Girls had lower satisfaction with health and self esteem and more physical and emotional discomfort. Pre-placement adverse experiences were associated with increased risks.

CONCLUSIONS

Adolescent self-report of the domains of health for those in foster care was better than expected, based on literature review and qualitative data for the larger study. Potential explanations for this inflation of status and functioning include the need for self-protection in foster care, the familiarity of testing regimes by children in foster care with some social desirability effect, and their paradoxical responses to pre-placement problems. Data including qualitative and significant other-reported data may be necessary to gain an accurate portrayal of the health status of adolescents in foster care.

Social competence and social support as mediators between comorbid depressive and conduct problems and functional outcomes in middle school children

This study examined the roles of social competence and social support as potential mediators of the association between psychopathology and functional outcomes in a middle school sample (n=521). Participants were stratified into four psychopathology risk groups (depression only, conduct problems only, comorbid depression and conduct problems, low symptoms) based on screening during early 6th grade. Functional outcomes were 6th grade point average (GPA) and parent rating of global adaptive functioning in their 7th grade student. Low levels of social competence were found to mediate the association between symptoms and both lower grades and global functioning for adolescents with depressive symptoms alone and with comorbid symptoms, but not for those with conduct problems alone. Lack of social support mediated the association between psychiatric symptoms and lower grades for adolescents with depression alone and comorbid symptoms, but not for those with conduct problems alone. These findings suggest that intervention to improve social competence and social support may enhance functional outcomes, especially for youth with depressive symptoms or comorbid depressive and conduct symptoms.

Validity of the health profile-types of the Spanish Child Health and Illness Profile-Adolescent Edition (CHIP-AE)

OBJECTIVE

To develop and validate a simplified, easy to interpret scoring system based on the health profile-types taxonomy for the Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE).

METHODS

The CHIP-AE was administered to a 1453 Spanish adolescents. Hierarchic and nonhierarchical cluster analyses, as well as conceptual considerations, were used to identify exhaustive, mutually exclusive health profile-types based in four CHIP-AE domain scores: Satisfaction, Discomfort, Resilience, and Risks. Validity of the health profile-types was assessed by testing expected differences among adolescents according to sex, age, socioeconomic status, and self-reported conditions. Logistic models were built.

RESULTS

A total of 13 health profile-types (10 that best fitted the data and three additional considered conceptually necessary) were identified. The largest group of adolescents was in the "Excellent health" or "Good health" types (43.4%), although 11.2% were in the "Worst health" profile. According to a priori hypotheses, being a girl (OR = 1.81; 95% CI = 1.26-2.60), older age (OR = 1.80; 1.26-2.57), and self-reported recurrent (OR = 2.49; 1.72-3.60) and psychosocial disorders (OR = 4.38; 2.92-6.56) were associated to the likelihood of a "Worst health" profile-type.

CONCLUSIONS

The Spanish CHIP-AE health profile-types offer a simplified method to describe adolescents' patterns of health, which is valid and similar to the original US taxonomy. This can facilitate interpreting the instrument scores and using it for needs assessment, although additional research is required.

Measuring children's health-related quality of life after trauma

Consideration of children's health-related quality of life (HRQOL) after injury is a critical aspect of outcome in assessing the effectiveness of trauma care. Numerous instruments are available today for measuring the HRQOL of injured children. HRQOL instruments reflect the subjective perspective of the impact an injury or disease has on a child's physical, emotional, and social well being. Most studies to date have examined children's HRQOL during the first year postinjury, relatively little is known about children's long-term HRQOL after trauma. Most trauma outcome studies have included children with heterogeneous injuries so the impact of specific injuries on HRQOL outcomes has not been well established. The majority of outcome studies have focused on injured children who have been hospitalized, however the research should be extended to the emergency department because a large proportion of injured children are treated and released from there. In addition to documenting recovery, investigators should use HRQOL instruments to evaluate the quality of care we offer injured children and their families. Rigorously conducted HRQOL assessment will provide valuable information that we can use to successfully optimize children's recovery after trauma.

Assessment of children's health-related quality of life in the United States with a multidimensional index

OBJECTIVE

Using nationally representative data, we examined biological, medical system, and sociodemographic factors that are associated with health-related quality of life as measured by a multidimensional index that accounts for a wide range of child health domains.

METHODS

Children aged > or = 6 years (N = 69,031) were drawn from the 2003/2004 National Survey of Children's Health. A random 25% sample was used to create a 12-item index of health-related quality of life with a range of 0 to 100, based on the conceptual framework of the Child Health and Illness Profile. Bivariate and multivariable regression analyses were conducted to identify the unadjusted and independent associations of key biological, medical system, and sociodemographic variables with health-related quality of life.

RESULTS

The index mean was 72.3 (SD: 14.5), median value was 73.7, and range was 11.1 to 99.9. Only 0.2% of children had a score at the ceiling. In multivariable regression analysis, the following variables were independently associated with lower health-related quality of life: biological factors (greater disease burden, severe asthma, and overweight status); medical system factors (unmet medical needs, lack of a regular health care provider, Medicaid insurance, or being uninsured previously during the year); and sociodemographic factors (older age groups, lower family education, single-mother family, having a smoker in the household, black race, and poverty).

CONCLUSIONS

Health-related quality of life in the United States is poorest for children and youth in lower socioeconomic status groups, those with access barriers, adolescents compared with children, and individuals with medical conditions. A multidimensional health-related quality-of-life index is an alternative to conventional measures (eg, mortality) for national monitoring of child health.

Self-perceived health, functioning and well-being of very low birth weight infants at age 20 years

OBJECTIVE

To examine the self-perceived health of very low birth weight (VLBW; <1.5 kg) infants during young adulthood.

STUDY DESIGN

The population included 241 VLBW and 232 normal birth weight (NBW) controls who completed the Child Health and Illness Profile: Adolescent Edition (CHIP-AE) at 20 years of age. The CHIP-AE includes six domains: Satisfaction, Comfort, Resilience, Achievement, Risk Avoidance, and Disorders, and 13 profiles that characterize patterns of health. Results were compared between VLBW and NBW subjects adjusting for sex and sociodemographic status.

RESULTS

VLBW subjects did not differ from NBW controls in the domains of Satisfaction or Comfort but reported less Resilience (effect size [ES] -0.19, P < .05), specifically in physical activity and family involvement. They reported better Achievement, specifically in work performance (ES 0.28, P < .05), more Risk Avoidance (ES 0.43, P < .001), and significantly more long-term medical, surgical, and psychosocial disorders. Similar proportions of VLBW and NBW subjects reported Excellent (15% vs 11%), Average (27% vs 34%), and Poor (12% vs 13%) profiles of health.

CONCLUSIONS

VLBW subjects report similar health, well-being, and functioning compared with NBW controls and greater risk avoidance. However, we are concerned that their lesser resilience may prove detrimental to their future adult health.

Reliability and convergent and discriminant validity of the Child Oral Health Impact Profile (COHIP Child's version)

OBJECTIVES

The purpose of the current study was to assess the reliability as well as the convergent and discriminant validity of the Child Oral Health Impact Profile (COHIP). The questionnaire consisted of five domains that assessed oral health, functional well-being, social-emotional well-being, school environment, and self-image. COHIP was designed to measure self-reported oral health-related quality of life (OHRQoL) of children between ages 8 and 15 years old, using both positively and negatively worded items.

METHODS

Children were recruited from pediatric, orthodontic, and craniofacial clinical settings in the USA and Canada. A comparison group of children not seeking dental treatment was recruited from two US elementary schools. Participants included 157 pediatric, 152 orthodontic and 110 patients with craniofacial anomalies, and 104 community-based participants. Scale reliability was assessed with Cronbach's alpha coefficient. Retest reliability was examined by intraclass correlation and paired t-test for a subset of participants who did not report a health change. Discriminant validity was assessed in two ways: (i) the COHIP scores of the four groups of children (three clinical and one community-dwelling) were compared by anova and (ii) for two of the clinical groups, the association between COHIP scores and clinical indices was calculated. Convergent validity was examined using partial Spearman correlations between COHIP scores and Global Health Ratings controlling for demographic variables.

RESULTS

The children (n = 523) averaged 11.6 years (SD = 1.60); 51.6 % were female; and represented diverse ethnicities (black = 22.4%, Latino = 32.1%, white = 35.1%, other 10.4%). Overall COHIP scores ranged from 28 to 135 (mean +/- SD, 99.0 +/- 19.2) for the children. Scale reliability for the overall COHIP was excellent: Cronbach's alpha coefficient = 0.91 for the overall score. The test-retest reliability of the overall COHIP was also excellent (ICC = 0.84) and there was no statistically significant shift in scores over time. Discriminant validity was supported by significant differences (P = 0.003 overall COHIP) among the three clinical groups: the craniofacial group reported the lowest overall COHIP quality of life scores of the clinical groups. Within the pediatric dental group, children with greater dental decay reported lower COHIP scores suggesting a lower OHRQoL (r = -0.26, P = 0.02) and within the orthodontic group, children with larger overjet reported lower COHIP scores (r = -0.25, P = 0.005). Controlling for the effect of the participants' age, gender, and ethnicity, the association between the overall COHIP score and Global Health rating was statistically significant (P < 0.05) and similar in strength for the three clinical groups (pediatric dental = 0.29, orthodontic = 0.23, and craniofacial = 0.24) and highest for the community group (0.36).

CONCLUSION

The overall COHIP showed excellent scale reliability overall and test-retest reliability. Both discriminant and convergent validity of the COHIP were supported by the comparisons among and within the four groups of children. Further testing will examine the utility of the instrument in both clinical and epidemiological samples.

A Primer on Health-Related Quality of Life in Chronic Pain Medicine

BACKGROUND

Pain is a complex and individual experience that is often difficult for patients to fully describe using a conventional pain intensity scale. Health-related quality of life is an additional metric by which to assess patients' subjective perspective on their chronic pain experience and its adverse effect on their lives. Health-related quality of life encompasses those aspects of health and well-being valued by patients, specifically, their physical, emotional, and cognitive function, and their ability to participate in meaningful activities within their family, workplace, and community.

METHODS

A methodical search of the medical literature was undertaken to identify the most commonly applied health-related quality of life measurement instruments. These measurement instruments were then assessed within the context of chronic pain medicine clinical practice and research.

RESULTS

This primer provides an overview of the concept of health-related quality of life as a clinical measurement and the specific means by which to measure health-related quality of life across various cultures in adults, as well as in children and adolescents, suffering from chronic pain conditions.

CONCLUSIONS

We have the ability and impetus to routinely assess adult and pediatric health-related quality of life in chronic pain medicine. However, further attention needs to be focused on overcoming barriers to the more widespread measurement of health-related quality of life. A valid preference-based, utility measure of health-related quality of life is a requirement for performing a cost-utility (cost-effectiveness) analysis and undertaking formal decision analysis modeling.

A multi-centre, randomised, open-label study of atomoxetine compared with standard current therapy in UK children and adolescents with attention-deficit/hyperactivity disorder (ADHD)

OBJECTIVE

To assess the broader efficacy (i.e., improvements in quality of life/functional outcomes) of atomoxetine compared with standard current therapy (SCT) in UK paediatric patients with ADHD and to explore clinician/parent/child perceptions of ADHD.

RESEARCH DESIGN AND METHODS

A total of 201 patients with ADHD were randomised into this multi-centre, open-label study to receive atomoxetine (n = 104) or SCT (n = 97) for 10 weeks. Broader efficacy was assessed using the parent-rated Child Health and Illness Profile-Child Edition (CHIP-CE) total (global) t-score. Secondary outcome measures included the five CHIP-CE domains; parent-rated Family Burden of Illness Module (FBIM); investigator-rated ADHD-Rating Scale; investigator-rated Clinical Global Impression (CGI)-Severity/Improvement scales; and child-rated Harter Self-Perception Profile (HSPP).

RESULTS

Quality of life of children/adolescents with ADHD was extremely compromised at baseline (CHIP-CE total t-scores: atomoxetine, 23.2 +/- 12.2; SCT, 23.9 +/- 11.0), and improved during the 10-week study for both groups; the CHIP-CE score was statistically significantly higher for patients treated with atomoxetine (38.4 +/- 1.3) compared with SCT (30.8 +/- 1.3) at week 10 (p < 0.001). ADHD-RS, CGI-Severity, and CGI-Improvement scores were significantly different between the groups in favour of atomoxetine (p < 0.001). There was a statistically significant difference between the groups in the HSPP Social Acceptance domain in favour of atomoxetine, but not in the five other HSPP domains or FBIM total score. Atomoxetine was well-tolerated.

CONCLUSIONS

Results from this open-label trial show that atomoxetine is superior to SCT in addressing broader efficacy and functional outcomes in UK children/adolescents with ADHD. This study contributes to the understanding of broader efficacy in children with ADHD, and is timely in light of recent NICE guidance.

Cost-utility analysis of cochlear implants in Korea using different measures of utility

CONCLUSIONS

All cost-utility ratios obtained using the various measures of utility except quality well-being (QWB) were below 25,000 dollars per quality-adjusted life year (QALY). Therefore, treatment of post-lingual deaf adults with cochlear implants improves the quality of life at a reasonable direct cost and appears to produce net savings for Korean society.

OBJECTIVES

To determine the quality of life and the cost consequences of cochlear implants for deaf adults.

PATIENTS AND METHODS

We performed a cost-utility analysis using data from 11 post-lingual deaf adults who had received cochlear implants between 1990 and 2002 in Seoul, Korea. The average age of the participants was 49.6 years. The main outcome was the direct cost per QALY calculated using the visual analog scale (VAS), health utility index (HUI), EuroQol (EQ-5D) measure and QWB measure. Costs and utility were discounted 3% annually.

RESULTS

Recipients used implants for an average of 5.6 years. The mean VAS, HUI, EQ-5D, and QWB score increased by 0.33 (from 0.27 before implantation to 0.60 at survey), 0.36 (0.29 to 0.65), 0.26 (0.52 to 0.78), and 0.16 (0.45 to 0.61), respectively. The discounted direct cost was 22,320 dollars, which yielded a cost-utility ratio of 19,223 dollars per QALY using VAS, 17,387 dollars per QALY using HUI, 24,604 dollars per QALY using EQ-5D, and 40,474 dollars per QALY using QWB.

Assessing Health Status and Health Care Utilization in Adolescents with Chronic Kidney Disease

Few validated health status measures have been assessed in children with chronic kidney disease (CKD). The objective was to assess the validity of a generic health status measure, the Child Health and Illness Profile-Adolescent Edition (CHIP-AE), in adolescents with CKD. A case-control study was performed (1) to assess scores on the CHIP-AE in adolescents with CKD compared with two control groups of age-, socioeconomic-, and gender-matched peers and (2) to compare health of patients who had chronic renal insufficiency (CRI), were on dialysis, and were posttransplantation. Seven pediatric nephrology centers recruited 113 patients (mean age, 14 yr; 39 CRI, 21 dialysis, 53 posttransplantation). Compared with 226 control subjects, patients with CKD had lower overall satisfaction with health and more restriction in activity. Positively, patients with CKD had more family involvement, better home safety and health practices, and better social problem-solving skills and were less likely to participate in risky social behaviors or socialize with peers who engaged in risky behavior. Patients who received dialysis were less physically active and experienced more physical discomfort and limitations in activities than did transplant or CRI patients. It is concluded that patients with CKD have poorer functional health status than age-matched peers. Among CKD patients, dialysis patients have the poorest functional health status. These results suggest that the CHIP-AE can be used to measure functional health status in adolescent patients with CKD.

Health-related quality of life assessment in hematologic disease

Evaluating health-related quality of life (HRQL) for children who have benign hematologic disorders can: (1) aid in the evaluation of different therapies and emerging new technologies; (2) serve as an invaluable source of anticipatory guidance, for current and future patients; and (3) serve an important evaluative function of clinical services or programs to identify potential areas in which additional services, supports, or interventions are needed. The past 20 years have been marked by the dramatic growth in the field of HRQL research, although much of the progress in conceptualization, instrument development, and refinement has occurred in adults. Pediatric health services researchers and their clinical colleagues have had to grapple with the methodologic challenges in evaluating HRQL in children. This article includes a discussion of instrumentation, respondent selection, and study design consideration in the evaluation of HRQL in children who have benign hematologic disorders.

Measuring health status and quality of life for US children: relationship to race, ethnicity, and income status

OBJECTIVE

Accurately measuring the health of the increasingly diverse population of US children requires instruments that are comparable and valid across cultures, economic background, and language. This paper asks: Has the field of pediatric health status measures reached this level of comprehensiveness?

METHODS

Children's health status and quality of life measures commonly used in the United States were reviewed to assess how they have included racial/ethnic minority and low-income groups. Four generic and 2 condition-specific instruments (asthma) were examined for total sample size, percent of sample from racial/ethnic and low-income groups, language availability, translation methods for US-Spanish, reading level, and separately reported psychometric findings and outcomes/scores.

RESULTS

Most measures have included minority groups, usually African American or Hispanic children, although with little information by Hispanic subgroup. Children's measures have generally been tested on relatively small samples, without separate analyses by subgroups. When done, tests of reliability and validity find few differences from the general population. Some studies report information on health by racial or ethnic group, but the findings are inconclusive. Economic status is usually measured in some way, but rarely are psychometric findings examined separately by income. When differences in health outcome are reported by income, lower income children usually have poorer health.

CONCLUSIONS

Much has been accomplished in advancing health status measures for children. Next-generation issues include the influence of race, ethnicity, and income on health and health reports.

Validity of the Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE)

OBJECTIVES

To assess the structural, convergent, discriminant, and criterion validity of the Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE) and to compare results with the U.S. version.

SUBJECTS

A sample of adolescents aged 12 to 19 attending schools and representative of the school-aged population in Barcelona, Spain (n = 902).

MEASURES

Exploratory factor analyses were performed, and results compared with the U.S. version. The Child Depression Inventory (CDI) and the State-Trait Anxiety Inventory (STAIC) were administered to a subgroup of adolescents to assess convergent and discriminant validity. Criterion validity was assessed by using receiver operating characteristic (ROC) curves to examine the ability of the CHIP-AE academic performance subdomain to predict school grades.

RESULTS

The Spanish version has 6 defined domains with a factor structure showing minor differences from the U.S. version. Higher correlations were found between the CDI and STAIC and CHIP-AE subdomains of emotional discomfort and self-esteem (range. 0.48-0.80, P<0.01) than with scales measuring dissimilar concepts. The area under the ROC curve was 0.83 (95% confidence interval, 0.75-0.92) for the number of failed subjects (none/one or more) related to academic performance.

CONCLUSIONS

The underlying theoretical model of the Spanish version of the CHIP-AE functions well in Spain, and the Spanish version has acceptable levels of convergent, discriminant, and criterion validity. Sensitivity to change and the use of the health profiles need to be assessed.

The Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE)

The aim of the study was to obtain a conceptually equivalent Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE), and to test its feasibility, reliability and preliminary construct validity. The methodology used for adaptation was forward-back translation, including two focus groups with adolescents and a panel of experts. Reliability and validity were assessed in healthy convenience samples from school settings (n = 417). Three different illness groups (n = 67) were used to examine differences in health status between healthy, acutely ill, chronically ill and mentally ill adolescents. Preliminary construct validity was examined by comparing mean scores for each of the subdomains to determine if they differed in predicted ways according to age, gender and illness group. The majority of items (154 out of 203) were conceptually equivalent to the original version. Some items (46) had to be modified to increase clarity and/or to adapt them for use in Spain and 3 items were considered not applicable. Single construct subdomains achieved alpha coefficients between 0.65 and 0.92, and intraclass correlation coefficients (ICC) between 0.57 and 0.93. The mentally ill group presented the worst scores in most domains. The Spanish CHIP-AE is acceptable for Spanish adolescents and shows adequate metric characteristics, which are similar to those reported in the US version.

[Reference population values for the Spanish Child Health and Illness Profile-Adolescent Edition (CHIP-AE) using a representative school-based sample]

AIM

The Child Health and Illness Profile (CHIP-AE) is a generic health status instrument for adolescents aged 12-19 years adapted for use in Spain. The aim of this study was to obtain reference population values of the Spanish version of the CHIP-AE.

METHODS

The CHIP-AE was administered to a representative sample of adolescents from schools in Barcelona. The sample was selected by using cluster-sampling, stratified by type of school (public or private) and an ecological socioeconomic index (Indice de Capacidad Familiar: low, middle, and high). The CHIP-AE scores were standardized to a mean of 20 and a standard deviation (SD) of 5. Means and percentiles were computed. Means were compared by age, gender, and socioeconomic status using analysis of variance.

RESULTS

The response rate was 81% (n = 902). The distribution of the CHIP-AE scores presented a wide range with scores generally skewed toward positive health status. Nevertheless, the results suggest that the sample selected from a general population was not free of health problems. Twenty-five percent of adolescents presented scores below 17.2 in the domain of discomfort, indicating an effect size of 0.56 standardized SD units. The distribution of scores in the reference samples from Barcelona was similar to the original results in Baltimore (USA), with some marginal differences in individual risks.

CONCLUSIONS

The CHIP-AE systematically gathers information on health domains in adolescents. The results from this reference sample will allow comparisons with adolescents from other regions, and/or with different health problems, as well as description of inequalities in health during adolescence.

Outcomes research in pediatric settings: recent trends and future directions

OBJECTIVE

Pediatric outcomes research examines the effects of health care delivered in everyday medical settings on the health of children and adolescents. It is an area of inquiry in its nascent stages of development.

METHODS

We conducted a systematic literature review that covered articles published during the 6-year interval 1994-1999 and in 39 peer-reviewed journals chosen for their likelihood of containing child health services research. This article summarizes the article abstraction, reviews the literature, describes recent trends, and makes recommendations for future work.

RESULTS

In the sample of journals that we examined, the number of pediatric outcomes research articles doubled between 1994 and 1999. Hospitals and primary care practices were the most common service sectors, accounting for more than half of the articles. Common clinical categories included neonatal conditions, asthma, psychosocial problems, and injuries. Approximately 1 in 5 studies included multistate or national samples; 1 in 10 used a randomized controlled trial study design. Remarkably few studies examined the health effects of preventive, diagnostic, long-term management, or curative services delivered to children and adolescents.

CONCLUSIONS

Outcomes research in pediatric settings is a rapidly growing area of inquiry that is acquiring breadth but has achieved little depth in any single content area. Much work needs to be done to inform decision making regarding the optimal ways to finance, organize, and deliver child health care services. To improve the evidence base of pediatric health care, more effectiveness research is needed to evaluate the overall and relative effects of services delivered to children and adolescents in everyday settings.

Social class gradients and health in childhood

OBJECTIVE

To determine if there are social class gradients in health in children aged 6 to 11 years.

METHODS

Self and parent reports of health of children in 5 sites across the United States were assessed using the Child Health and Illness Profile-Child Edition. Distribution of scores in 4 domains: satisfaction (with health); comfort; resilience; and risk avoidance were used to create profiles of health. Social class was defined as a composite of parental education and work participation.

RESULTS

Social class gradients were found for all but the satisfaction domain and for most subdomains in the parent version; the most notable gradient was in the risk avoidance domain, with better health the higher the social class. Apparent gradients did not reach statistical significance in the child reports. Children from a higher social class were more likely to be in excellent/average health and less likely to be in poor health profiles than were lower class children.

CONCLUSIONS

The findings generally mirror those from a prior study of adolescents, using the same conceptual framework for health and the same measure of social class, and are consistent with a cumulative effect for most aspects of health, and with a critical-period effect for risky behaviors.

Children's health status instruments: their potential application in the emergency department

OBJECTIVE

To provide an overview of child health status instruments and their potential application by emergency medicine researchers.

CONCLUSIONS

Numerous instruments have recently been developed to measure children's physical, mental, and social health using sound principles of measurement science. These instruments differ from traditional clinical benchmarks of impairment. Health is conceived to be multidimensional and is measured from the child's and/or parents' perspective. Child health status instruments can be used to broaden the evaluation of emergency care in the following ways: 1) to evaluate emergency department (ED) interventions in terms of improvements in children's everyday activities and well-being; 2) to assess the appropriateness of ED disposition and follow-up services; and 3) to detect underlying health and social problems. Using these instruments in the ED will be challenging. Methodologic issues remain regarding the measurement of children's health. The most pressing issues are the absence of a universal definition of children's health, the need to take into account the developmental and social contexts of children, and the difficulties in eliciting information from very young children. In addition, the ED presents its own set of challenges. These include the lack of pre-injury/pre-illness measures, the absence of case-mix severity instruments, and the difficulty of isolating the effect of ED treatment on patients' health.

RECOMMENDATIONS

Despite these challenges, it is time to use pediatric health status instruments in emergency medicine. Only with their adoption will instruments improve and advances in methodology occur. As patients, providers, and policy makers increasingly focus their attention on the nonfatal consequences of injury and illness, the broader use of these measures becomes imperative.

Child/parent-assessed population health outcome measures: a structured review

AIMS

To identify generic measures of health-related quality of life (HRQL) for children and adolescents developed for use within general populations. Instruments are evaluated on the basis of evidence relating to their reliability and validity.

METHODS

Systematic literature searches were used to identify instruments, which were then assessed against predefined criteria. Information relating to instrument content, population, reliability and validity was extracted from published papers.

RESULTS

Sixteen instruments were identified that had been evaluated among a general population of children or adolescents. Four instruments had reported data on both internal consistency and test-retest reliability. All except two instruments had undergone some degree of construct validation.

CONCLUSIONS

The evidence suggests that the Child Health Questionnaire (CHQ) has been the most extensively evaluated for younger populations but is available as a parent-completed measure only. The new version of the Child Health and Illness Profile (CHIP-CE) is particularly promising and has parallel child- and parent-completed versions for young ages. The weight of evidence suggests that versions of these two instruments are suitable for older children. The Warwick Child Health and Morbidity Profile could be used where information on morbidity and health service contacts is required. Once basic psychometric criteria are fulfilled, instruments should be chosen by assessing their content and design in the light of the prospective application.

A taxonomy of adolescent health: development of the adolescent health profile-types

OBJECTIVES

The aim of this study was to develop a taxonomy of health profile-types that describe adolescents' patterns of health as self-reported on a health status questionnaire. The intent was to be able to assign individuals to mutually exclusive and exhaustive groups that characterize the important aspects of their health and need for health services.

METHODS

Cluster analytic empirical methods and clinically based conceptual methods were used to identify patterns of health in samples of adolescents from schools and from clinics that serve adolescents with chronic conditions and acute illnesses. Individuals with similar patterns of scores across multiple domains were assigned to the same profile-type. Results from the empirical and conceptually based methods were integrated to produce a practical system for assigning youths to profile-types.

RESULTS

Four domains of health (Satisfaction, Discomfort, Risks and Resilience) were used to group individuals into 13 distinct profile-types. The profile-types were characterized primarily by the number of domains in which health is poor, identifying the unique combinations of problems that characterize different subgroups of adolescents.

CONCLUSIONS

This method of reporting the information available on health status surveys is potentially a more informative way of identifying and classifying the health needs of subgroups in the population than is available from global scores or multiple scale scores. The reliability and validity of this taxonomy of health profile-types for the purposes of planning and evaluating health services must be demonstrated. That is the purpose of the accompanying study.
