A two-year prospective study of the health-related quality of life of children with chronic illness--the parents' perspective

Quality of Life, Participation, and Individualized Support in a Community-Based Yoga Class: A Case Series

PURPOSE

To assess quality of life and participation in children with disabilities following a community-based yoga class, to examine the feasibility of implementing a community-based program with individualized support, and to make recommendations for the development of future programs.

SUMMARY OF KEY POINTS

Four children participated in a 10-week yoga class, with doctor of physical therapy students providing individualized physical and behavioral support. Children improved in components of the Children's Assessment of Participation and Enjoyment (CAPE) following the program; however, changes in quality of life on the Pediatric Quality of Life Inventory (PedsQL) were inconsistent. Parents provided feedback regarding the family's experience and reported that the children improved behavior, communication, and relationships following the yoga class.

WHAT THIS CASE ADDS TO EVIDENCEBASED PRACTICE

A community-based yoga class for children with disabilities using individualized support is feasible and can improve participation and enjoyment in recreational activities.

Parent-Child Agreement on Health-Related Quality of Life in Congenital Glaucoma

Purpose

We assess parent-child agreement regarding child's health-related quality of life (HRQoL) in children operated for congenital glaucoma (CG).

Methods

A total of 121 children aged 8 to 18 years (mean age, 11.8 years) operated for CG (mean duration since surgery, 10.2 years) and their parents (mean age, 36.5 years) completed the child and parent versions of the Kidscreen-27 questionnaire, respectively. Psychometric properties of Kidscreen-27 were assessed using Rasch analysis, and child–parent agreement regarding child's HRQoL was investigated using the Bland-Altman limits of agreement (LoA) method.

Results

Minor modifications in the rating scale and deletion of few misfitting items resulted in a psychometrically robust Kidscreen-23 questionnaire. Average parental HRQoL score was higher than the child's own ratings, with a significant difference between their scores (mean ± standard deviation [SD] difference = 0.53 ± 2.58 logits, P = 0.02; lower LoA [95% CI], −4.52 [−5.31 to −3.72] and upper LoA [95% CI], 5.58 [4.79–6.38]). The range of child–parent agreement was wide and bidirectional, with parents tending to underestimate and overestimate their child's HRQoL. Younger children and girls showed greater discordance in their HRQoL with parental reports than adolescents and boys, respectively.

Conclusions

Discordance between CG child's self-report of HRQoL and parent's report indicate that both groups perceive the broader impact of living with CG very differently.

Translational Relevance

The HRQoL as reported by the child with CG and by his/her parent should be viewed as being complementary, rather than interchangeable. Both assessments should be taken into account in clinical practice and research studies.

Assessment of health-related quality of life in Egyptian adolescents with type 1 diabetes: DEMPU survey

BACKGROUND

Type 1 diabetes (T1D) is a serious chronic illness that imposes significant morbidity and mortality with a major impact on the quality of life (QoL) that became a core issue in diabetes care. Understanding the effect of diabetes on QoL is important for day-to-day clinical management and also for public health policy initiatives aiming at improving health outcomes for those with diabetes. The objective of the study was to assess the QoL in adolescents with T1D and assess the applicability of the use of the "Quality of Life for Youth" questionnaire at the Diabetes, Endocrine and Metabolism Pediatric Unit (DEMPU) clinic.

METHODS

One hundred and fifty adolescents (82 males and 68 females) (10-18 years), with T1D of at least 1 years' duration, completed the questionnaire that evaluated symptoms related to diabetes, treatment, activities, parent issues, worries about diabetes and health perception. Higher scores indicated a more negative impact of diabetes and poorer QoL.

RESULTS

Males showed a significantly better mean QoL score than females (p=0.004). Different age groups showed different QoL scores (p=0.047). Urban adolescents had a better QoL than rural counterparts (p=0.02). Adolescents with poor QoL had generally lower educational level (p=0.02). Better metabolic control was associated with a better QoL (p=0.01). However, duration of diabetes and body mass index (BMI) had no statistically significant effect on QoL.

CONCLUSIONS

QoL had a variable significant association with certain socio-demographic and clinical characteristics of diabetics (sex, residence, educational level as well as metabolic control).

Generic and disease-specific quality of life in adolescents with type 1 diabetes: comparison to age-matched healthy peers

BACKGROUND

This study aimed to evaluate the health-related quality of life (HRQoL) of adolescents with type 1 diabetes (T1DM) on the basis of the pediatric quality of life inventory™ (PedsQL™) generic and diabetes-specific modules, and to compare it to that of healthy peers.

METHODS

This retrospective case-control study involved 650 participants between ages of 13 and 19 years including 296 adolescents with T1DM from four diabetes centers and 354 healthy peers matched for age and gender from three different cities of the country. Participants completed the validated PedsQL™ for assessing the HRQoL. The analysis included an independent t-test to compare the means of the total and subscales of the PedsQL™ between boys and girls as well as between a healthy group and a group with T1DM. Gender differences in exercise, insulin therapy modalities were evaluated with the Pearson χ2-test.

RESULTS

Adolescents with T1DM have similar HRQoL in all domains when compared to their healthy counterparts. Females report worse HRQoL regardless of the presence of the disease. Insulin pump therapy facilitates better glycemic control and HRQoL. Regular exercise positively correlates with the generic HRQoL in both groups; however, it has no relationship with glycemic control.

CONCLUSIONS

Optimal metabolic control and improved HRQoL are the eventual goals of diabetes management. Despite the difficulties, adolescents with diabetes can manage their disease well and live normal lives, similar to their healthy peers. Although diabetes-related problems exist, it seems that regular exercise and staying physically active, as well as promoting insulin pump therapy where it is applicable are related to favorable HRQoL.

Health-Related Quality of Life in Spanish Children With Coeliac Disease

OBJECTIVES

The aim of the study was to assess health-related quality of life (HRQOL) using the Coeliac Disease Dutch Questionnaire (CDDUX) in Spanish children with coeliac disease.

METHODS

The CDDUX was cross-culturally adapted according to international consensus guidelines. HRQOL was assessed in coeliac members of the Madrid Coeliac Association ages 8 to 18 years using the adapted CDDUX. Cronbach α coefficient was determined as a measure of intraquestionnaire reliability and intraclass correlation coefficients as a measure of reliability between scores awarded by children and parents. Demographic and clinical variables associated with HRQOL were also assessed.

RESULTS

A total of 1602 children of 3122 registered Madrid Coeliac Association members ages 8 to 18 years were invited to participate. The questionnaire was completed by 480 families (30%): 214 only by parents, 214 by parents and their children, and 52 only by children. Cronbach α coefficient for the total score for parents was 0.90, and for children 0.88 (0.75-0.90 by scales). Mean total (standard deviation [SD]) HRQOL scores in children and parents were 55.5 (SD 12.7) and 53.89 (SD 12.19), respectively, with no differences detected in paired comparisons between the 2 groups. Significantly worse HRQOL scores were recorded in children showing a nonclassical clinical presentation, in those not adhering to treatment and in those reporting difficulties in following the diet.

CONCLUSIONS

The CDDUX questionnaire emerged as reliable for use in Spanish children with celiac disease. Overall, both children and parents felt the disease had no substantial negative impacts on patient HRQOL.

Health-related quality of life in paediatric asthma: Children's and parents' perspectives

This study aimed to describe the quality of life of a group of Portuguese children with asthma, to explore the association between health-related quality of life (HRQL), asthma severity, child's characteristics and parental psychopathology. Additionally, the concordance between the children's HRQL self-report and the parents' HRQL proxy was assessed. Fifty children with asthma (7-13 years) and their primary caregiver participated in the study by filling out the DISABKIDS-37 and other self-report questionnaires. Results for the DISABKIDS-37 supported a good internal consistency and associations between the facets and the global score, in the two versions of the questionnaire. Children and their caregivers scored the child's HRQL positively. Parents of children with an asthma diagnosis for a longer period reported better HRQL. The distribution of the HRQL scores in the child's version showed differences across categories of subjective severity rated by children and across categories of asthma control assessed by the physician. The group with uncontrolled asthma obtained lower HRQL scores than the other groups. There was a lack of convergence between self-report and parent's report of HRQL, with the exception of the physical limitation facet. Asthma severity assessed by the child and parental psychopathology explained 28% of the variance in the children's self-rated HRQL. Findings reinforce that children and caregivers' reports are complementary to each other and support the recommendation to use both information sources.

Reliability and validity of PedsQL for Portuguese children aged 5-7 and 8-12 years

Background

Pediatric Quality of Life Inventory (PedsQL) is a measure to assess health-related quality of life (HRQoL) in children and adolescents. It is formed by 23 items adapted to children age and includes a parent proxy report version. With four multidimensional subscales and three summary scores, it measures health as defined by WHO. The concepts measured by this instrument are ‘physical functioning’ (8 items), ‘emotional functioning’ (5 items), ‘social functioning’ (5 items) and ‘school functioning’ (5 items). It also measures a ‘total scale score’ (23 items), a ‘physical health summary score’ (8 items) and a ‘psychosocial health summary score’ (15 items). The aim of this paper is to present the main results of the cultural adaptation and validation of the PedsQL into European Portuguese.

Methods

The Portuguese version was the result of a forward-backward translation process, with a cognitive debriefing analysis, guaranteeing face validity and semantic equivalence. Children aged 5–7 and 8–12 were randomly selected and were asked to fill a socio-demographic data survey and the Portuguese versions of PedsQL and KINDL, another HRQoL measure for children and adolescents. They were divided into three groups, healthy children, children with type I diabetes and children with spina bifida.

The reliability was tested for reproducibility (ICC) and internal consistency (Cronbach’s alpha). The construct validity (known-groups discriminant validity) was supported by differences between self-reports from healthy children and children with chronic conditions, and from children with chronic diseases and their parents. The criterion validity was tested after the correlations of the scores obtained by both children and adolescents HRQoL assessment instruments.

Results

A total of 179 children and 97 parents were recruited. PedsQL demonstrated good levels of reproducibility (r > 0.95 in all versions) and acceptable levels of internal consistency with Cronbach’s alpha at 0.70 on most scales. Concordance values between children’s and parents’ perceptions ranged between 0.36 and 0.78 and the correlations with KINDL questionnaire were excellent, supporting concurrent validity.

Conclusions

The Portuguese version of the PedsQL demonstrated acceptable psychometric properties for future research and clinical practice for children aged 5–12.

Overview of psychosocial health among youth with spinal cord injury

BACKGROUND

Psychosocial health can be conceptualized as being mentally, emotionally, and socially well. Little is known about normative psychosocial development among children and adolescents with spinal cord injury (SCI).

OBJECTIVE

To provide a comprehensive overview of psychosocial health of 410 youth with SCI from ages 2 to 18 years. To understand developmental trends, data are presented separately for ages 2-5, 6-12, 13-15, and 16-18 years.

METHODS

Youth with SCI were recruited from 1 of 3 pediatric specialty hospitals within a single hospital system. Structured surveys assessing community participation, quality of life (QOL), and mental health (including anxiety and depression) were completed by youth with SCI (for ages 6-18) or their primary caregivers (for ages 2-5). Descriptive statistics were used to assess how patients scored on all standardized measures.

RESULTS

Of the 410 participants, 56% were male, 64% were Caucasian, 66% had paraplegia, and 55% had complete injuries. On average, the participants were 12 years old (SD 4.87) at interview and 7.26 years old (SD 5.97) at injury. Psychosocial health outcomes were described for each of the 4 age groups: 2-5 years (n = 52), 6-12 (n = 142), 13-15 (n = 82), and 16-18 (n = 134) years.

CONCLUSIONS

As compared to published norms, this sample of youth with SCI seemed to be experiencing decreased levels of community participation and QOL, but also decreased levels of anxiety and depression. These data provide needed information to clinicians regarding how youth with SCI may typically experience psychosocial health and where their patients fit into that typical experience.

Health-related quality of life in children and adolescents with celiac disease: from the perspectives of children and parents

Aim. To examine how celiac children and adolescents on gluten-free diet valued their health-related quality of life, and if age and severity of the disease at onset affected the children's self-valuation later in life. We also assessed the parents' valuation of their child's quality of life. Methods. The DISABKIDS Chronic generic measure, short versions for both children and parents, was used on 160 families with celiac disease. A paediatric gastroenterologist classified manifestations of the disease at onset retrospectively. Results. Age or sex did not influence the outcome. Children diagnosed before the age of five scored higher than children diagnosed later. Children diagnosed more than eight years ago scored higher than more recently diagnosed children, and children who had the classical symptoms of the disease at onset scored higher than those who had atypical symptoms or were asymptomatic. The parents valuated their children's quality of life as lower than the children did. Conclusion. Health-related quality of life in treated celiac children and adolescents was influenced by age at diagnosis, disease severity at onset, and years on gluten-free diet. The disagreement between child-parent valuations highlights the importance of letting the children themselves be heard about their perceived quality of life.

The proxy problem anatomized: child-parent disagreement in health related quality of life reports of chronically ill adolescents

Background

Discrepancy between self-reports and parent-proxy reports of adolescent health-related quality of life (HRQoL) has been repeatedly acknowledged in the literature as the proxy problem. However, little is known about the extent and direction of this discrepancy. The purpose of this study is to explore to what extent and in what direction HRQoL self-reports of adolescents with chronic conditions and those of their parents differ.

Methods

A cross-sectional survey was conducted among adolescents suffering from chronic conditions and their parents. Socio-demographic and disease-related characteristics were collected and information about consequences of the chronic condition was assessed. HRQoL was measured with KIDSCREEN-10 and DISABKIDS condition generic measure (DCGM-10). Agreement was analysed through defining a threshold of agreement based on half of the standard deviation of the HRQoL score with the highest variance. Agreement occurred if the difference between adolescent and parent scores was less than or equal to half of the standard deviation. Intra-class correlation coefficients and Bland-Altman plots were also computed. The characteristics associated with direction of disagreement were statistically tested with one-way ANOVA and Chi-square tests.

Results

584 paired HRQoL scores were obtained. Ratings from both adolescents and parents were high, compared to European norm data. Differences between adolescents and parents were statistically significant, yet relatively small. Disagreement existed in both directions: in 24.5% (KIDSCREEN-10) and 16.8% (DCGM-10) of the cases adolescents rated their HRQoL lower than did their parent, while in 32.2% (KIDSCREEN-10) and 31.7% (DCGM-10) of the cases the opposite was true. Adolescent's age, educational level and type of education, parent's educational level, number of hospital admissions and several other disease-related factors influenced direction of disagreement.

Conclusions

In a reasonable proportion of cases the adolescent and parent agreed on the adolescent's HRQoL (43-51% of the cases) and most disagreement tended to be minor. Thus, the proxy problem may be smaller than presented in the literature and its extent may differ per population. As adolescents are expected to become partners in their own health care, it is recommended to focus on adolescents' own perceptions of HRQoL.

Análise psicométrica inicial da versão brasileira do DISABKIDS Atopic Dermatitis Module

OBJETIVO: Analisar as propriedades psicométricas iniciais da versão brasileira de instrumento de avaliação da qualidade de vida relacionada à saúde de crianças e adolescentes com dermatite atópica. MÉTODOS: Estudo transversal realizado com amostra de 52 crianças e adolescentes, com idades entre oito e 18 anos, diagnosticados com dermatite atópica, e seus responsáveis, recrutados em serviço de dermatologia de hospital universitário na cidade de São Paulo, SP, em 2009. Foram avaliadas a validade de construto, a confiabilidade de consistência interna e a correlação entre as respostas de crianças e adolescentes e seus responsáveis da versão brasileira do Atopic Dermatitis Module (DISABKIDS-ADM). RESULTADOS: A confiabilidade de consistência interna foi satisfatória, com coeficiente alfa de Cronbach aceitável para as dimensões constantes no instrumento (0,7024/0,8124 e 0,7239/0,8604). A análise multitraço-multimétodo para validade convergente mostrou valores maiores que 0,30 para todos os itens. Quanto à validade discriminante, a análise revelou resultados satisfatórios. A concordância entre as versões self e proxy foi avaliada pelo coeficiente de correlação intra-classe, com valores de 0,8173 para impacto e 0,7629 para estigma. CONCLUSÕES: Diante dos resultados encontrados, considera-se que o instrumento DISABKIDS-ADM pode ser utilizado por pesquisadores brasileiros depois de finalizado seu processo de validação, por seus resultados iniciais apontarem propriedades psicométricas satisfatórias, que permitem considerá-lo um instrumento válido e confiável.

[Translation and cultural adaptation of the brazilian version of Disabkids® Atopic Dermatits Module (ADM)]

The objective of this study was to translate and make the cultural adaptation of the Brazilian version of the DISABKIDS® Atopic Dermatitis Module (ADM), an instrument used to measure the health-related quality of life of children and adolescents with atopic dermatitis. The instrument has 12 items answered using a Likert scale, with two versions: self and proxy. The study counted with a sample of 18 Brazilian children and adolescents with atopic dermatitis, of ages ranging between 8 and 18 years, and their respective parents or caregivers. The process involved the following steps of translation-back translation and semantic evaluation. The former revealed good acceptance of the translated version of the instrument, which participants considered having items of easy understanding. After completing the process of validation in the country, the instrument will become available to Brazilian researchers to measure health-related quality of life, as well as to compare results from Brazil to that of other cultures in which the instrument has already been validated.

Transitioning care of an adolescent with cystic fibrosis: development of systemic hypothesis between parents, adolescents, and health care professionals

This qualitative study explored the experience of parents and adolescents living with cystic fibrosis prior to the transfer of the adolescent's care from a pediatric to an adult health care facility. Semistructured interviews were conducted with seven families receiving care from a specialized cystic fibrosis clinic; parents and adolescents were interviewed separately, followed by a group interview with members of a health care team comprising eight professionals from the clinic. Interviews were analyzed through a systemic lens which accounts for interaction and reciprocity in relationships. The parents' experience was marked by suffering and uncertainty that remained unexpressed to the health care team, even though team members had known the family since the child was first diagnosed. Findings led to identifying a systemic hypothesis that accounted for the interactions and relational processes between parents and the health care team. This hypothesis may guide the development of systemic family nursing interventions that target this complex, relational, transition process.

Icelandic and United States families of adolescents with asthma: predictors of health-related quality of life from the parents' perspective

AIMS

To evaluate cultural differences in sociodemographic factors, illness severity and parents' perception of their adolescent's quality of life for Icelandic and USA families of adolescents with asthma; and to determine predictors of parent-rated quality of life.

BACKGROUND

Asthma is known to have an impact on the quality of life of affected adolescents and their families, but few studies have addressed parents' perception of their adolescent's health-related quality of life.

DESIGN

Cross-sectional exploratory study.

METHOD

The study involved families of adolescents with asthma included 15 from Iceland and 15 from USA, recruited from paediatric practices. Parent and adolescent participants completed questionnaires; this study is based on the parent responses. Data were collected from January-May 2006.

FINDINGS

While parents from Iceland and USA were similar in demographic characteristics, parents from Iceland rated their children's health-related quality of life (PedsQL(TM) 3.0, Varni 1998) more positively than did USA parents, even though Icelandic parents were more likely than their USA counterparts to report that their adolescent's asthma is severe. Significant predictors of parent-rated quality of life included location (higher scores for Icelandic parents), gender (higher scores for parents of boys), exposure to second hand smoke in the home (higher scores for those not exposed) and frequency of troublesome wheezing (higher scores for lower frequency).

CONCLUSION

Quality of life has been acknowledged as an essential health outcome measure. Even though gender difference was not found in asthma severity, parents of boys perceived their adolescent's quality of life as more positive compared with parents of girls. It might be helpful for Icelandic and USA families to integrate into care delivery models, cultural differences in parent-rated quality of life.

RELEVANCE TO CLINICAL PRACTICE

Asthma management interventions may improve quality of life for adolescents with asthma by reducing symptoms. Interventions promoting smoke-free homes and enhanced self-monitoring to prevent exacerbations may improve quality of life.

Avaliação da qualidade de vida de pacientes com fibrose cística por meio do Cystic Fibrosis Questionnaire

OBJETIVO: Avaliar a qualidade de vida (QV) de pacientes com fibrose cística (FC) acompanhados em um centro universitário de referência em atendimento a FC. MÉTODOS: Estudo transversal com a aplicação do Cystic Fibrosis Questionnaire (CFQ) e escore de Shwachman em pacientes com FC entre abril de 2008 e junho de 2009. RESULTADOS: Participaram 75 pacientes, com média de idade de 12,5 ± 5,1 anos (variação: 6,1-26,4 anos). Os pacientes foram divididos em três grupos de acordo com a idade: grupo I (< 12 anos), II (12-14 anos) e III (> 14 anos). As pontuações mais altas e mais baixas no CFQ foram para o domínio alimentação do grupo III (89,3 ± 16,2) e para o domínio social no grupo II (59,5 ± 22,3), respectivamente. Houve uma diferença significativa no domínio tratamento entre os grupos III e I (p = 0,001). Pacientes com escore de Shwachman < 70 apresentaram diferenças significativas em relação aos domínios social (grupo I; p = 0,045), respiratório (grupo II; p = 0,053) e digestivo (p = 0,042) quando comparados aqueles com escores > 70. No grupo III, não se observou associação entre gravidade e QV. Nos grupos I e II, não se observou diferenças entre os pacientes com VEF1 < 80% do previsto e os demais pacientes em todos os domínios do CFQ. Entretanto, no grupo III, as médias dos pacientes com VEF1 < 80% do previsto foram significativamente menores nos domínios físico (p = 0,012), imagem corporal (p = 0,031), respiratório (p = 0,023), emocional (p = 0,041) e papel social (p = 0,024). CONCLUSÕES: A avaliação da QV em pacientes com FC é importante, pois contribui para uma melhor aderência ao tratamento.

Longitudinal assessment of health-related quality of life in an observational cohort of patients with cystic fibrosis

BACKGROUND

Patient-reported outcomes (PROs) are increasingly used to evaluate the efficacy of new treatments and the progression of chronic diseases. The Cystic Fibrosis Questionnaire-Revised (CFQ-R) is a disease-specific, PRO measure of health-related quality of life (HRQOL). We evaluated associations between changes in health status over time and HRQOL in a national CF database.

METHODS

Using the Epidemiologic Study of Cystic Fibrosis (ESCF) data, we identified participants who had completed age-appropriate CFQ-R assessments on two occasions separated by 9-15 months. Next, we developed multivariate regression models to test whether associations existed between (1) changes in respiratory signs/symptoms and changes in the respiratory health domains of the CFQ-R, (2) changes in nutritional health status and changes in the nutritional health domains of the CFQ-R, and (3) changes in treatment complexity and changes in the Treatment Burden scale of the CFQ-R.

RESULTS

We analyzed 1,947 pairs of assessments: 337 child (mean age 8.9, range 6-13 years), 581 parent (mean age of child 8.8, range 6-13 years), 398 adolescent (mean age 15.3, range 14-17 years), and 631 adult (mean age 26.9, range 18-73 years). On average, we found little change in both health status indicators and CFQ-R domain scores over 1 year. Significant associations over time, however, were found between increases in respiratory symptoms and worse CFQ-R Respiratory Symptom scores, declining weight and worsening scores on CFQ-R nutritional health domains, and increases in treatment complexity and worsening CFQ-R Treatment Burden scores for parent respondents.

CONCLUSION

Health status and HRQOL changes were small over a 1-year period in this CF population. However, changes in respiratory symptoms and weight were associated with significant changes on relevant CFQ-R scores, indicating that this PRO is sensitive to changes in health status over time.

Factors affecting quality of life in Taiwanese survivors of childhood cancer

AIM

This paper is a report of a pilot study to examine the significance, direction, and magnitude of the relationship of risk factors, protective factors, and resilience to quality of life in survivors of childhood cancer, and to explore what these variables meant to participants in order to better understand the quantitative findings and to assess the validity of the instruments with this population.

BACKGROUND

Cancer survivors contend with physical, psychosocial and emotional consequences of the disease and its treatment. There has been little research in Taiwan assessing these outcomes and, as survivor numbers increase, appropriate interventions need to be implemented. Haase's Adolescent Resilience Model was used as the theoretical framework.

METHODS

A mixed methods design was used to assess the relationship between the variables for survivors of leukaemia and brain cancers. Ninety-eight participants completed quantitative tools and interviews, and the data were collected in 2006.

FINDINGS

Survivors of leukaemia had better quality of life than those with brain tumours. This is attributed to more positive protective factors, fewer illness-related and individual risk factors and more positive resilience scores. Findings were congruent with similar studies from other countries. Qualitatively, participants believed that better quality of life meant less loss of self, a more integrated self, less chronic fear, and an ability to rebound and achieve personal control over one's life.

CONCLUSION

Interventions and assessment of their efficacy are necessary to help survivors capitalize on their strengths, to decrease their individual risks and to promote resilience promote self-control.

Dornase alfa improves the health-related quality of life among Brazilian patients with cystic fibrosis--a one-year prospective study

SUMMARY BACKGROUND

Health-related quality of life (HRQOL) measurements provide valuable information about the psychological and social impact of treatment on patients with cystic fibrosis (CF). This study evaluated the HRQOL of Brazilian patients with CF and assessed the changes in HRQOL domains over 1 year after dornase alfa (Pulmozyme) introduction.

PATIENTS AND METHODS

One hundred fifty-six stable patients with CF and 89 caregivers answered the Portuguese-validated version of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at baseline (T(0)), and at 3 (T(1)), 6 (T(2)), 9 (T(3)), and 12 (T(4)) months of follow-up. Eighteen patients were excluded because they did not fulfill the inclusion criteria. The patients were analyzed in two groups: those aged 6-11 years and those aged 14 years and older. ANOVA for observed repeated results and the last observation carried forward (LOCF) method for missing data were used for the statistical analysis.

RESULTS

After 1 year of follow-up, there was significant improvement in respiratory symptoms (T(4) - T(0) = 8.1; 95% confidence interval (95% CI) = [2.1;14.0]; effect size (ES) = 0.35; P < 0.001), Emotional Functioning (T(4) - T(0) = 5.6; 95% CI = [1.1;10.1]; ES = 0.31; P < 0.05), Social Functioning (T(4) - T(0) = 6.0; 95% CI = [1.3;11.7]; ES = 0.31; P < 0.05), Body Image (T(4) - T(0) = 11.9; 95% CI = [4.1;19.7]; ES = 0.42; P < 0.05), and Treatment Burden (T(4) - T(0) = 5.3; 95% CI = [0.3;10.3]; ES = 0.24; P < 0.05) domains in the younger group. A significant improvement in Role Functioning (T(4) - T(0) = 6.1; 95% CI = [1.1;11.1]; ES = 0.40; P < 0.05), Body Image (T(4) - T(0) = 12.6; 95% CI = [3.5;21.7]; ES = 0.46; P < 0.05), and Weight (T(4) - T(0) = 11.7; 95% CI = [1.8;21.6]; ES = 0.40; P < 0.05) was obtained in the older group. The caregivers' CFQ-R showed improvements in the Digestive Symptoms (T(4) - T(0) = 5.5; 95% CI = [1.5;9.4]; ES = 0.30; P < 0.05), Respiratory Symptoms (T(4) - T(0) = 7.6; 95% CI = [3.9;11.4]; ES = 0.48; P < 0.05), and Weight (T(4) - T(0) = 10.1; 95% CI = [1.6;18.6]; ES = 0.26; P < 0.05) domains.

CONCLUSION

The introduction of dornase alfa improved the HRQL of the patients with CF during the first year of treatment.

Changes in the health burden of a national sample of children with asthma

This paper focused on the extent to which factors that are modifiable by health policies or provider recommendations influenced the level and changes in the burden of childhood asthma. Demographic factors, access to health care services, and asthma control activities were posited to potentially influence the level and changes in health burden of children with asthma. The Medical Expenditure Panel Survey data from 1996-1999 on 3-11 year old U.S. children with asthma (N=784) were used. The findings of multilevel models of perceived burden indicated unfavorable trajectories among those families who had public health insurance. Asthma control activities were associated with favorable trajectories of both perceived and objectively measured burden. These findings emphasized the significance of asthma control and access to high quality and stable health care services as health policy targets.

Health-related quality of life measurement in cystic fibrosis: advances and limitations

Health-related quality of life (HRQoL) measurement in cystic fibrosis (CF) allows the inclusion of the patient's perspective in research and clinical practice. HRQoL scales have been used for many purposes and this review focuses on how HRQoL measurement has been implemented in CF research and care. Specifically, the review considers 1) the instruments used to measure HRQoL, 2) the factors that influence how people report HRQoL, 3) the monitoring of HRQoL in clinical practice, 4) HRQoL as an outcome measure in interventions and clinical trials and 5) whether HRQoL can predict survival. The challenge for the future is to use the available information to develop and evaluate psychological interventions that would be expected to improve HRQoL in children and adults with CF.

Factors that influence quality of life in rural children with asthma and their parents

INTRODUCTION

Among rural children with asthma and their parents, this study examined the relationship between parental and child reports of quality of life and described the relationship of several factors such as asthma severity, missed days of work, and asthma education on their quality of life.

METHODS

Two hundred one rural families with asthma were enrolled in a school-based educational program. Intervention parents and children participated in interactive asthma workshop(s) and received asthma devices and literature. Parent and child quality of life measurements were obtained before and after the intervention using Juniper's Paediatric Caregivers Quality of Life and Juniper's Paediatric Quality of Life Questionnaires. Asthma severity was measured using criteria from the National Asthma Education and Prevention Program guidelines.

RESULTS

There was no association between parent and child total quality of life scores, and mean parental total quality of life scores were higher at baseline and follow-up than those of the children. All the parents' quality of life scores were correlated with parental reports of missed days of work. For all children, emotional quality of life (EQOL) was significantly associated with parental reports of school days missed (P = .03) and marginally associated with parental reports of hospitalizations due to asthma (P = .08). Parent's EQOL and activity quality of life (AQOL) were significantly associated with children's asthma severity (EQOL, P = .009; AQOL, P = .03), but not the asthma educational intervention. None of the child quality of life measurements was associated with asthma severity.

DISCUSSION

Asthma interventions for rural families should help families focus on gaining and maintaining low asthma severity levels to enjoy an optimal quality of life. Health care providers should try to assess the child's quality of life at each asthma care visit independently of the parents.

Quality of life in children with Type 1 diabetes: a comparison of general and diabetes-specific measures and support for a unitary diabetes quality-of-life construct

AIMS

To assess the factor structure of the Pediatric Quality of Life Inventory (PedsQL) Diabetes Module and to compare the PedsQL general and diabetes-specific quality of life (QOL) measures regarding psychometric properties and relations to relevant outcomes.

METHODS

The instruments were completed by 447 children age 9 to 15.5 years with Type 1 diabetes > 1 year from four US paediatric diabetes clinics; parents completed the parallel parent-proxy measures. Principal components factor analysis was used to examine the factor structure of the PedsQL diabetes module. Analyses of the generic and diabetes QOL measures included psychometric properties, parent-child correlations and correlations with depression, adherence and glycated haemoglobin (HbA(1c)).

RESULTS

The factor structure of the PedsQL diabetes module did not support the original five subscales. Both one- and two-factor models were supported; however, parallel parent and child subscales did not emerge. While the generic and diabetes-specific measures of QOL were moderately to highly correlated with each other, the constructs were differentially associated with relevant diabetes outcomes. Generic QOL was more highly associated with depression than diabetes QOL. Conversely, diabetes QOL was more highly associated with adherence and HbA(1c), although this was seen to a greater extent for parent-proxy report than for child report.

CONCLUSIONS

Factor analysis of the PedsQL diabetes module supports the use of a total diabetes QOL score. Findings regarding the associations of the generic and diabetes modules with diabetes outcomes underscore the unique contribution provided by both generic and diabetes QOL.

Changes in health-related quality of life (HRQoL) in a population-based sample of children and adolescents after 3 years of follow-up

OBJECTIVES

To assess changes in health-related quality of life (HRQoL) in children and adolescents over a 3-year period and to examine factors associated with change.

METHODS

A representative sample of Spanish children and adolescents aged 8-18 years and their parents completed the KIDSCREEN-52 questionnaire at baseline and again after 3 years. Data were also collected on gender, pubertal development (PD), and family socio-economic status (SES). Change in HRQOL over time was evaluated using effect sizes (ES). Generalized estimating equations (GEE) were used to analyze associations among changes in KIDSCREEN scores, socio-demographic factors, and pubertal development.

RESULTS

Response rate at follow-up was 54% (n = 454). Overall, HRQoL worsened in eight out of the ten KIDSCREEN dimensions, with ES ranging from -0.10 (Moods and Emotions) to -0.34 (Psychological Well-being). The decrease was most marked in the intermediate age group (13-17 years of age at follow-up) and in girls. In the GEE models, pubertal development more strongly impacted changes in girls than in boys.

CONCLUSIONS

In this representative, population-based sample of children and adolescents, moderate decrements in HRQoL were observed after 3 years. Changes were particularly important among girls and in relation to pubertal development. These results could provide useful reference data for other longitudinal studies in population sub-groups.

Responsive parenting is associated with improved type 1 diabetes-related quality of life

BACKGROUND

Improved quality of life is an important treatment goal for children and adolescents with type 1 diabetes. While previous research supports a relationship between family environment and quality of life, little research has addressed the relationship of parenting style constructs to quality of life in children with chronic disease. The present investigation assesses the relationship of parent responsiveness and demandingness with diabetes-related quality of life among children and adolescents with type 1 diabetes.

METHODS

Baseline and 12-month follow-up self-report assessments were collected on a sample of 81 children with type 1 diabetes participating in an efficacy trial of a behavioural intervention to enhance adherence. The sample had a mean age of 13.3 years (SD=1.7) and duration of diabetes of 7.7 years (SD=3.7). Multiple regression analyses were conducted to determine the relationship of parent responsiveness and demandingness to diabetes-related quality of life at each time point.

RESULTS

After adjusting for demographic and diabetes characteristics, as well as diabetes-specific parent-child behaviours, parent responsiveness was significantly associated with baseline diabetes-related quality of life (beta=0.23; P=0.04). This relationship was sustained at 12-month follow-up (beta=0.22; P=0.04) after adjusting for baseline quality of life and treatment group assignment, suggesting that parent responsiveness is associated with improved quality of life.

CONCLUSIONS

Findings indicate the importance of a supportive and emotionally warm parenting style in promoting improved quality of life for children with type 1 diabetes. Appropriate parenting skills should be an element of diabetes family management health care.

Family-centered collaborative negotiation: a model for facilitating behavior change in primary care

PURPOSE

To describe a parent-child-based model that melds a family-centered interaction approach, Touchpoints, with brief negotiation strategies (an adaptation of motivational interviewing) to address health risks in children. An application of the model for addressing childhood overweight in the primary care setting is presented.

DATA SOURCES

Selected research, theoretical, and clinical articles; national recommendations and guidelines; and a clinical case.

CONCLUSIONS

Lifestyle health behaviors are learned and reinforced within the family; thus, changes to promote child health require family involvement. Interventions that engage parents and support parent-child relationships, while enhancing motivation and the abilities to change behavior, are recommended.

IMPLICATIONS FOR PRACTICE

Primary care is an appropriate setting for addressing lifestyle health behaviors. A collaborative partnership, rather than a prescriptive manner, is advocated for primary care providers when working to facilitate health-promoting behavior.

Parents of children with cystic fibrosis: how they hope, cope and despair

BACKGROUND

Cystic fibrosis is a chronic, life-threatening illness. Coping, vicarious hope and vicarious despair are constructs that may explain why some children and parents adjust well to cystic fibrosis, while others adjust poorly. Vicarious hope refers to parent expectations that desirable things will occur in their child's future, whereas vicarious despair refers to parent expectations that undesirable things will occur in their child's future. The aims of this study were: (1) to examine parent coping strategies and associations with child and parent adjustment to cystic fibrosis; (2) to investigate the effects of vicarious hope and vicarious despair on coping, parent adjustment and child adjustment; and (3) to examine distinctions between coping, vicarious hope and vicarious despair.

METHODS

Participants were 35 parents of children with cystic fibrosis.

RESULTS

Self-blame and behavioural disengagement were coping strategies associated with child and parent maladjustment. Social support predicted less parental emotional impact. Vicarious hope and vicarious despair predicted child mental health, parent anxiety and parent emotional impact.

CONCLUSIONS

Results indicate that vicarious hope and vicarious despair are distinct constructs from coping. Interventions directed at parent coping, vicarious hope and vicarious despair are implicated.

The health-related quality of life of children and adolescents in home-based foster care

OBJECTIVE

To compare the health-related quality of life (HRQL) of 326 children and adolescents aged 6-17 years living in home-based foster care in metropolitan Adelaide, South Australia with the HRQL of a random sample of 3,582 children aged 6-17 years living in the community in Australia.

METHOD

In both groups, HRQL was assessed using the 50-item version of the Child Health Questionnaire (CHQ-PF50) completed by caregivers/parents, and the 87-item self-report version of the Child Health Questionnaire (CHQ-CF87) completed by 13-17 year olds.

RESULTS

Young people in home-based foster care had significantly poorer HRQL in a wide range of different domains than those in the general community. Furthermore, among children in home-based foster care, those with mental health problems had significantly poorer HRQL in many domains than those without mental health problems. Demographic and placement characteristics of the children in home-based foster care were not significantly associated with differences in HRQL.

CONCLUSION

The findings highlight the importance of providing services and resources to improve the quality of life of children living in home-based foster care.

Quality of life in paediatric gastrointestinal and liver disease: a systematic review

OBJECTIVES

To identify and appraise all studies relating to and instruments developed to measure quality of life (QOL) in children with gastrointestinal or liver diseases.

METHODS

A literature search was undertaken using MEDLINE, EMBASE, CINAHL, and PsycINFO to identify relevant articles published up to the end of 2005. These were reviewed by both authors and data were extracted using a standardised form. Articles were excluded if no attempt was made to measure QOL, they did not relate to children ages <17 years, they did not relate to gastrointestinal or liver diseases, or they were review articles. Quality of life instruments identified were rated according to proposed criteria.

RESULTS

From a total of 2379 articles identified in the initial search, a total of 2309 were excluded, leaving 70 included studies. These were assigned to the following categories: inflammatory bowel disease, n = 17; cystic fibrosis, n = 20; liver disease, n = 11; surgery, n = 15; and miscellaneous, n = 7. These studies describe the impact that these diseases have on the QOL of affected children. A total of 11 disease-specific QOL instruments and 1 generic instrument with a chronic disease module were identified, but only 5 of these fulfilled the proposed quality criteria and can be recommended for future use.

CONCLUSIONS

Chronic gastrointestinal and liver diseases can have an enormous effect on the QOL of affected individuals and their families. A number of disease-specific paediatric QOL instruments have been developed and validated. Quality of life is an important outcome that should be incorporated into clinical practice and measured when treatments are evaluated. Future research should explore how QOL can best be improved in children in whom it is severely impaired.

Field testing of a European quality of life instrument for children and adolescents with chronic conditions: the 37-item DISABKIDS Chronic Generic Module

OBJECTIVES

The aim of this study was to shorten the Health-Related Quality of Life (HRQL) DISABKIDS Chronic Generic Measure (DCGM) for children and adolescents and to test its reliability, construct, and external validity.

STUDY DESIGN

1153 children and adolescents (8-16 years) with chronic health conditions (asthma, arthritis, epilepsy, cerebral palsy, diabetes, atopic dermatitis, cystic fibrosis) and their family were recruited from different paediatric clinical settings in seven European countries. A two-time assessment comprised reports on sociodemographics, health status and HRQL of children/adolescents.

RESULTS

The 37-item DCGM describes six dimensions (Independence, Physical Limitation, Emotion, Social Inclusion, Social Exclusion and Treatment) confirmed by Confirmatory Factor Analysis, multi-item scaling and item-goodness of fit to Rasch model. Internal consistency (Cronbach's alpha: 0.70-0.87) and test-retest reliability (ICC: 0.71-0.83) were satisfactory. Correlations between DCGM-37 and other HRQL instruments were the highest between dimensions evaluating similar concepts. Regarding discriminant validity of the DCGM-37, girls and older adolescents reported lower emotional we ll-being. Children belonging to families with low level of affluence and those with severe health conditions were found to have worse HRQL in all domains.

CONCLUSION

Reliability, construct validity as well as convergent and discriminant validity of the DCGM-37 were shown.

Monitoring quality of life in outpatients with cystic fibrosis: feasibility and longitudinal results

BACKGROUND

To investigate the feasibility of monitoring quality of life (QL) with cystic fibrosis (CF) in a clinical setting, to explore changes in subjective health and to describe the impact of multiple medical and psychosocial factors on the patients' QL.

METHODS

108 adolescent and adult outpatients (age 15-47 years, FEV(1) 20-125% of the predicted) answered the Questions on Life Satisfaction repeatedly parallel to each pulmonary function test (2-16 assessments per patient within 18 months). Multiple regression analysis determined the contribution of medical and psychosocial factors to the patients' QL.

RESULTS

Good acceptance of the instrument was observed. The completion time was between 5 and 29 min per assessment (median 11 min). QL remained quite stable (r(tt)=.69) with the previous QL score predicting most of the variance of the present score. Additionally, a longer interval between assessments, new colonization with Pseudomonas aeruginosa, infection exacerbations, partnership, vocation and living separately from parents significantly predicted QL at the second assessment. Pulmonary function varied independently of QL.

CONCLUSIONS

Medical factors such as pulmonary exacerbation and social living circumstances have an impact on the QL of patients with CF. Repeated QL assessments in clinical routine are feasible and useful to recognize the individual patient's adaptation to the disease.
