Health-related quality of life: gender differences in childhood and adolescence

Summary.: Objectives: To assess whether gender and age differences can be found in different aspects of health-related quality of life (HRQOL) of children and adolescents, and to what extent these results correspond to theoretical and empirical findings from developmental psychology. Methods: A newly developed HRQOL questionnaire was completed by 3 710 youths aged nine to 17years in seven European countries. The "Kidscreen 52” questionnaire consists of 10 scales operationalising aspects of the physical, psychological and social dimensions of HRQOL. With the use of ANOVA and effect sizes, the influence of age and gender on aspects of HRQOL is reported. Results: Children report a very good quality of life largely independent of gender. After 12years, HRQOL decreases in the majority of aspects. In the physical and psychological dimensions, a stronger decrease is found for females than for males. Conclusions: Children have higher HRQOL than adolescents in many aspects. With increasing age, HRQOL is frequently worse for females than for males. Examination of the individual aspects leads to a differentiation of the results with relevance for public healt

Identifying the sociodemographic determinants of subjective health complaints in a cross-sectional study of Greek adolescents

Background: Experience of common health symptoms without a clear physical or psychological cause, such as headache or dizziness, is often reported in adolescence. The present study attempted to investigate associations of self-reported subjective health complaints (SHC) with a number of sociodemographic factors of Greek adolescents. Methods: Questionnaires were administered to a Greek nationwide random school-based sample of adolescents aged 11 to 18 years and their parents in 2003. Data from 922 adolescent-parent pairs were analyzed (response rate = 63%). Adolescents’ reported subjective health complaints were assessed for their association with a number of sociodemographic factors: age, sex, type of area of residence according to level of urbanization, immigration background, parental education and employment status, family socioeconomic status and perceived quality of financial resources (PQFR). Multiple linear regression analysis was used to assess the association of the aforementioned factors with subjective health complaints as the dependent variable. Results: Most sociodemographic variables, apart from area of residence and immigration background, were independently associated with subjective health complaints in the univariate analyses. The multiple linear regression analysis, however, limited the factors that could predict adolescents’ subjective health complaints to four (age, sex, Family Affluence Scale score and perceived quality of financial resources). Some considerations regarding parental employment status and immigration background are highlighted. Conclusions: Our study highlights the sociodemographic components of subjective health complaints in the Greek adolescent population. The need to include adolescent-specific measures when collecting information on adolescents’ social background is underlined. Identifying vulnerable adolescent populations could lead to effective health promoting and preventive interventions

The KIDSCREEN-52 Quality of Life Measure for Children and Adolescents (KIDSCREEN-52-HRQOL): Reliability and Validity of the Korean Version

The KIDSCREEN-52 quality-of-life (KIDSCREEN-52-HRQOL) is a relevant, worldwide tool used for assessing the health-related quality of life in children and adolescents. The purpose of this study was to define measurement properties of the Korean version of the KIDSCREEN-52 HRQOL. The original questionnaire was translated following international translation guidelines. Analysis regarding psychometric properties showed that the Cronbach-alpha ranged from 0.77 to 0.95. The correlation coefficient between the PedQL and KIDSCREEN-52 dimensions were high for the assessments of similar constructs. Therefore, the Korean version of the KIDSCREEN-52 was found to be suitable for use in Korean adolescents

Association Between Experiencing Relational Bullying and Adolescent Health Related Quality of Life

This is the peer reviewed version of the following article: Kayleigh L. Chester, Neil H. Spencer, Lisa Whiting, and Fiona M. Brooks, ‘Association Between Experiencing Relational bullying and Adolescent Health-Related Quality of Life’, Journal of School Health, Vol. 87 (11): 865-872, November 2017, which has been published in final form at DOI: https://doi.org/10.1111/josh.12558.

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.BACKGROUND Bullying is a public health concern for the school-aged population, however, the health outcomes associated with the subtype of relational bullying are less understood. The purpose of this study was to examine the association between relational bullying and health-related quality of life (HRQL) among young people. METHODS This study utilized data from 5335 students aged 11-15 years, collected as part of the 2014 Health Behavior in School-aged Children (HBSC) study conducted in England. Data were collected through self-completed surveys. Multilevel analysis modeled the relationship between relational bullying and HRQL. Demographic variables (sex, age, ethnicity, socioeconomic status) and other forms of bullying were controlled for. RESULTS Experiencing relational bullying had a significant negative association with HRQL whilst controlling for other forms of bullying. Weekly relational bullying resulted in an estimated 5.352 (95% confidence interval (CI), −4.178, −6.526) decrease in KIDSCREEN-10 score compared with those not experiencing relational bullying. CONCLUSION Experiencing relational bullying is associated with poorer HRQL. The findings question the perception of relational bullying as being a predominantly female problem. Girls were more likely to report experiencing relational bullying, but the negative association with HRQL was equal for boys and girls.Peer reviewe

The impact of overweight and obesity on health-related quality of life in childhood – results from an intervention study

<p>Abstract</p> <p>Background</p> <p>The negative impact of overweight (including obesity) and related treatment on children's and adolescents' health-related quality of life (HRQoL) has been shown in few specific samples thus far. We examined HRQoL and emotional well-being in overweight children from an outpatient treatment sample as well as changes of these parameters during treatment.</p> <p>Methods</p> <p>In a cross-sectional design, self-reported HRQoL of 125 overweight (including obese) children who contacted a treatment facility, but had not yet receive treatment, were compared to 172 children from randomly selected schools using independent two-sample t-tests. Additionally, in a longitudinal design, the overweight children were retested by administering the same questionnaire at the end of the intervention (after one year). It included measures such as the body mass index (BMI), the general health item (GHI), the KINDL^R, and the Child Dynamic Health Assessment Scale (ChildDynHA). Comparisons were based on dependent t-tests and the Wilcoxon signed-rank test.</p> <p>Results</p> <p>Overweight children showed statistically significant impairment in the GHI (Cohen's d = 0.59) and emotional well-being (ChildDynha) (d = 0.33) compared to the school children. With respect to HRQoL, the friends dimension of the KINDL^Rwas significantly impaired in the overweight group (d = 0.33). However, no impairment was found for the total HRQoL score or other KINDL^Rsubdimensions. Regarding the longitudinal part of our study, most of the children improved their BMI, but the majority (87.5%) remained overweight. Nevertheless, the participants' perceived health, emotional well-being, and generic as well as disease-specific HRQoL improved during intervention.</p> <p>Conclusion</p> <p>The findings emphasize the importance of patient-reported outcomes such as HRQoL. Even though overweight and obesity might accompany most of the children throughout their lifetime, the impairment associated with this chronic condition can be considerably reduced. Opportunities of health promotion in overweight/obese children and adolescents are discussed.</p

Adolescent Family Characteristics Partially Explain Differences in Emerging Adulthood Subjective Well-Being After the Experience of Major Life Events: Results from the German KiGGS Cohort Study

Experiences from major life events (MLEs; e.g., starting work or living independently) accumulate in the transition to emerging adulthood. Adaption to such events, often operationalized as responses in subjective well-being (SWB), is highly diverse. This observation has prompted attempts to explain differences in SWB responses among individuals as well as events. Early family characteristics have been discussed as potentially enduringly beneficial or harmful for successful adaption to MLEs in emerging adulthood. In the current study, we investigated adolescent family characteristics as longitudinal predictors of emerging adult mental and physical SWB (direct associations) and their explanatory value for SWB differences after the experience of MLEs (indirect associations). Analyses were based on data from a German national cohort study of 6255 emerging adults (KiGGS survey; 46.6% male; mean age = 22.78 years, standard deviation = 3.26 years) who had participated in the baseline study 11 years prior. Results showed that, while experiencing unemployment or severe illness was most negatively related to SWB, high educational attainment had the most positive correlation. Adolescent family characteristics were longitudinal predictors of emerging adult SWB and partially explained differences in SWB after the experience of several MLEs. Most notably, adolescent family characteristics were indirectly associated with emerging adult SWB via permanent relationships, educational attainment, and unemployment. The results provide a basis for the better understanding and further development of research and targeted intervention or prevention measures to facilitate adaptive capacity and reduce adverse effects from certain events on SWB in the transition to emerging adulthood.Peer Reviewe

Psychometric properties of the quality of life questionnaire for children with CP

This paper describes the development and psychometric properties of a condition-specific quality of life instrument for children with cerebral palsy (CP QOL-Child). A sample of 205 primary caregivers of children with CP aged 4 to 12 years (mean 8y 5mo) and 53 children aged 9 to 12 years completed the CP QOL-Child. The children (112 males, 93 females) were sampled across Gross Motor Function Classification System (GMFCS) levels (Level I=18%, II=28%, III=14%, IV=11%, V=27%). Primary caregivers also completed other measures of child health (Child Health Questionnaire; CHQ), QOL (KIDSCREEN), and functioning (GMFCS). Internal consistency ranged from 0.74 to 0.92 for primary caregivers and from 0.80 to 0.90 for child self-report. For primary caregivers, 2-week test-retest reliability ranged from 0.76 to 0.89. The validity of the CP QOL is supported by the pattern of correlations between CP QOL-Child scales with the CHQ, KIDSCREEN, and GMFCS. Preliminary statistics suggest that the child self-report questionnaire has acceptable psychometric properties.

Measuring adolescents' HRQoL via self reports and parent proxy reports: an evaluation of the psychometric properties of both versions of the KINDL-R instrument

<p>Abstract</p> <p>Background</p> <p>Several instruments are available to assess children's health-related quality of life (HRQoL) based on self reports as well as proxy reports from parents. Previous studies have found only low-to-moderate agreement between self and proxy reports, but few studies have explicitly compared the psychometric qualities of both. This study compares the reliability, factorial validity and convergent and known group validity of the self-report and parent-report versions of the HRQoL KINDL-R questionnaire for children and adolescents.</p> <p>Methods</p> <p>Within the nationally representative cross-sectional German Health Interview and Examination Survey for Children and Adolescents (KiGGS), 6,813 children and adolescents aged 11 to 17 years completed the KINDL-R generic HRQoL instrument while their parents answered the KINDL proxy version (both in paper-and-pencil versions). Cronbach's alpha and confirmatory factor-analysis models (linear structural equation model) were obtained. Convergent and discriminant validity were assessed by calculating the Pearson's correlation coefficient for the Strengths and Difficulties Questionnaire. Known-groups differences were examined (ANOVA) for obese children and children with a lower familial socio-economic status.</p> <p>Results</p> <p>The parent reports achieved slightly higher Cronbach's alpha values for the total score (0.86 vs. 0.83) and most sub-scores. Confirmatory factor analysis revealed an acceptable fit of the six-dimensional measurement model of the KINDL for the parent (RMSEA = 0.07) and child reports (RMSEA = 0.06). Factorial invariance across the two versions did not hold with regards to the pattern of loadings, the item errors and the covariation between latent concepts. However the magnitude of the differences was rather small. The parent report version achieved slightly higher convergent validity (r = 0.44 – 0.63 vs. r = 0.33 – 0.59) in the Strengths and Difficulties Questionnaire. No clear differences were observed for known-groups validity.</p> <p>Conclusion</p> <p>Our study showed that parent proxy reports and child self reports on the child's HRQoL slightly differ with regards to how the perceptions, evaluations and possibly the affective resonance of each group are structured and internally consistent. Overall, the parent reports achieved slightly higher reliability and thus are favoured for the examination of small samples. No version was universally superior with regards to the validity of the measurements. Whenever possible, children's HRQoL should be measured via both sources of information.</p
