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 selfadministered 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 cutoff 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 cutoff points to define adolescents with health problems.

Objective: To identify currently available generic and disease-specific health-related quality of life (HRQOL) instruments for children and adolescents up to 19 years old, to describe their content, and to review their psychometric properties. Study Design: Previous reviews on the subject and a new literature review from 2001 to December 2006 (MEDLINE, the ISI Science Citation Index, HealthSTAR and PsycLit) were used to identify measures of HRQOL for children and adolescents. The characteristics (country of origin, age range, type of respondent, number of dimensions and items, name of the dimensions and condition) and psychometric properties (reliability, validity, and sensitivity to change) of the instruments were assessed following international guidelines published by the Scientific Committee of the Medical Outcomes Trust. Results: In total, 30 generic and 64 disease-specific instruments were identified, 51 of which were published between 2001 and 2005. Many generic measures cover a core set of basic concepts related to physical, mental and social health, although the number and name of dimensions varies substantially. The lower age limit for self-reported instruments was 5-6 years old. Generic measures developed recently focused on both child self-report and parent-proxy report, although 26% of the disease-specific questionnaires were exclusively addressed to proxy-respondents. Most questionnaires had tested internal consistency (67%) and to a lesser extent test-retest stability (44.7%). Most questionnaires reported construct validity, but few instruments analyzed criterion validity (n = 5), structural validity (n = 15) or sensitivity to change (n = 14). Conclusions: The development of HRQOL instruments for children and adolescents has continued apace in recent years, particularly with regard to disease-specific questionnaires. Many of the instruments meet accepted standards for psychometric properties, although instrument developers should include children from the beginning of the development process and need to pay particular attention to testing sensitivity to change.

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 health-related quality of life in adolescence
Acta Paediatrica, 2007
Background: There is a paucity of research about health-related quality of life (HRQL) among adolescents, as studies have to a large extent focused on adults. The main aim was to provide information for future studies in this growing field by presenting normative data for the Short Form 36 (SF-36) and the Hospital Anxiety and Depression Scale (HADS) for Swedish adolescents and young adults. Additionally, the influence of age and gender, as well as method of administration, was investigated. Methods: A sample of 585 persons aged 13-23 was randomly chosen from the general population, and stratified regarding age group (young adolescents: 13-15 years; older adolescents: 16-19 years, and young adults: 20-23 years) and gender (an equal amount of males and females). Within each stratum, the participants were randomized according to two modes of administration, telephone interview and postal questionnaire, and asked to complete the SF-36 and the HADS. Descriptive statistics are presented by survey mode, gender, and age group. A gender comparison was made by independent t-test; and one-way ANOVA was conducted to evaluate age differences. Results: Effects of age and gender were found: males reported better health-related quality of life than females, and the young adolescents (13-15 years old) reported better HRQL than the two older age groups. The older participants (16-23 years old) reported higher scores when interviewed over the telephone than when they answered a postal questionnaire, a difference which was more marked among females. Interestingly, the 13-15-year-olds did not react to the mode of administration to the same extent. Conclusion: The importance of taking age, gender, and method of administration into consideration, both when planning studies and when comparing results from different groups, studies, or over time, is stressed.
Health-related quality of life in portuguese children and adolescents
Psicologia: Reflexão e Crítica, 2012
The KIDSCREEN is a European cross-cultural and standardized instrument that assesses ten quality of life dimensions in children, adolescents and their parents. This instrument is used to validate evidences to support general inferences on quality-of-life measures obtained by the Portuguese version of KIDSCREEN-10 for children and adolescents, in the context of a survey research carried on in Portugal. The present study focuses only on the KIDSCREEN children and adolescents' versions. A sample of 8072 Portuguese children and adolescents attending the 5 th grade (19.3%), 6 th grade (19.2%), 7 th grade (20.3%), 8 th (21.6%) and 10 th grade (19.7%) in Portuguese schools were inquired, with a mean age of 13.2; SD 2.06, randomly distributed regarding gender. The Portuguese version of KIDSCREEN-10 instrument showed a good Internal Consistency of .78. Chosen fit indexes indicate good fit to the data. Specifically in the final solution the RMSEA was lower than .03 and the upper limit of 90% confidence interval was lower than .05, and CFI was higher than .95. Results indicated that the current 10-item structure is invariant across age groups, nationality and socioeconomic level. The KIDSCREEN-10 questionnaire is a reliable instrument to estimate the perception of quality of life in children and adolescents. Psychometric guidelines are presented for the Portuguese population aged 10 to 16 years old. Keywords: Assessment, health-related quality of life, children and adolescents. Resumo O KIDSCREEN é um instrumento europeu transcultural e padronizado que avalia dez dimensões da qualidade de vida de crianças, adolescentes e seus pais. Este instrumento é usado para validar evidências a fim de apoiar inferências gerais sobre medidas de qualidade de vida obtidas pela versão portuguesa do KIDSCREEN-10 para crianças e adolescentes, no contexto de uma pesquisa de investigação feita em Portugal. O presente estudo centra-se apenas na versão KIDSCREEN para adolescentes e crianças. Uma amostra de 8.072 crianças e adolescentes portugueses frequentando a 5ª série (19,3%), 6ª série (19,2%), 7ª série (20,3%), 8ª série (21,6%) e 10ª série (19,7%) em escolas do país foram intrevistadas, com uma idade média de 13,2; DP 2,06, distribuídos aleatoriamente em relação ao sexo. A versão portuguesa do instrumento KIDSCREEN-10 mostrou uma boa consistência interna de 0,78. Os índices de ajuste escolhidos indicam bom ajuste aos dados. Especificamente na solução final o RMSEA foi inferior a 0,03, o limite superior do intervalo de confiança de 90% foi inferior a 0,05 e CFI foi superior a 0,95. Resultados indicaram que a estrutura atual do item 10 é invariável entre grupos de idade, nacionalidade e nível socio-econômico. O questionário KIDSCREEN-10 é um instrumento confiável para estimar a percepção da qualidade de vida em crianças e adolescentes. Orientações psicométricas são apresentadas para a população portuguesa entre 10 e 16 anos de idade. Palavras-chave: Avaliação, qualidade de vida relacionada à saúde, crianças e adolescentes. * The authors acknowledge the European Kidscreen Group for technical and scientific guidance and the Project Aventura Social Team for collaboration in data collection and analysis.

Self-rated health (SRH) in adolescence is known to be associated with health outcomes in later life. We carried out a trend analysis on data coming from three waves of data collected in 32 countries (mostly European) from 2002 to 2010 coming from the Health Behaviour in School-Aged Children surveys. SRH in adolescents was assessed using a Likert scale (excellent, good, fair and poor). Responses were dichotomized into 'excellent' vs. 'rest'. Country, age and gender groups were compared based on the odds ratio of declaring excellent SRH in 2010 with respect to 2002 and 2006. The trend for European adolescents indicates an improvement over the last decade, although, in the majority of countries, a higher proportion of adolescents rate their health as excellent during the period 2002-06 with respect to the second half of the decade (2006-10).Girls were found to constantly rate their health as poorer, compared to their male peers, in all countries. Age has also a very sta...
Journal of Adolescent Health, 2001
Methods: We show the results of a self-reported HRQL assessment by the Vécu et Santé Perçue de l'Adolescent (VSP-A) multidimensional questionnaire, conducted on a population of 3061 adolescents. The VSP-A produces a score for each of the seven dimensions (relationships with friends, relationships with parents, school life, inaction, psychological distress, future, and energy/vitality) and a global score. The result is compared with the answers of the parents to the same multidimensional HRQL questionnaire reworded for them (VSP-P) and to the perceived health self-reported by the adolescents on a visual analogue scale (VAS). The adolescents filled both the VSP-A and VAS questionnaires twice at a 1-month interval.
Validation of a French health-related quality of life instrument for adolescents: The VSP-A
Quality of Life Research, 2000
The French Health Ministry, stating the limits of traditional indicators to take into account the different aspects of adolescent health, declared adolescent health status assessment as a priority. Thus a French health-related quality of life (HRQL) generic self-administered indicator was developed on the adolescent's viewpoint for healthy and ill adolescents of 11–17: the VSP-A, Vécu et Santé Perçue de l'Adolescent,
The Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE)
2003
The aim of the study was to obtain a conceptually equivalent Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE TM), 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 ¼ 417). Three different illness groups (n ¼ 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 a 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.
Validity of the Morningness‐Eveningness Scale for Children among Spanish Adolescents
Chronobiology International, 2007
Adolescents tend to be much later chronotypes than other age groups. This circadian phase delay is attributed as much to biological as psychosocial factors. Because the consequences of this change on performance and health have been documented, questionnaires to identify morning and evening-type adolescents are necessary. The aim of the present study was to validate a Spanish version of the Morningness-Eveningness Scale for Children (MESC) by means of several relevant psychological variables as external criteria. A sample of 623 urban high school students completed the MESC and selfreported measures of sleep behaviors, subjective alertness, physical performance, and mood. On the whole, results indicate a good validity of MESC. Significant differences in the self-reported ratings between morning and evening types were obtained by time-of-day. These results provide preliminary support for the Spanish version of MESC.
