RESUMEN

OBJECTIVES: The EQ-TIPS was developed to measure the Health-Related Quality of Life in infants/toddlers. Considering the rapid development in this period, this study aimed to investigate age-related variations in EQ-TIPS performance. METHODS: Data from 551 infants/toddlers living with a health condition were analysed. Infants/toddlers were grouped by age: 0-6 months (n = 100), 6-12 months (n = 95), 12-24 months (n = 147), and 36-48 months (n = 97). Differences in item responses and item correlations across age groups were calculated by Kruskal-Wallis and Spearman's correlations, respectively. RESULTS: The report of problems was significantly higher for movement, play, and communication in the 36-48-month group compared to the 0-6-month group. There were strong correlations (r > 0.50) across all age groups between play and movement and communication and social interaction/play; neither pain nor eating showed a clear pattern of association. CONCLUSIONS: There is an age-related difference in the reporting of items linked to developmental milestones (movement, play, and communication) with most problems reported in the 36-48-month group when deviation from peers and continued dependence on caregivers is notable. Consideration should be given to including broader examples of play in the EQ-TIPS. Redefining the items to represent social communication and/or (social) emotion, rather than communication and social interaction, may be warranted. Future research should explore the psychometric performance of items to further inform item inclusion and/or revision.

RESUMEN

OBJECTIVES: The EuroQol Group is exploring the development of a health-related quality of life measure for toddlers and infant populations (EuroQoL Toddler and Infant Populations [EQ-TIPS]) aged 0 to 36 months. This study aimed to report on the cross-cultural adaptation and validity of the South African Afrikaans EQ-TIPS. METHODS: The development of the Afrikaans EQ-TIPS followed the EuroQol guidelines including forward-backward translation and cognitive interviews with 10 caregivers of children aged 0 to 36 months. Thereafter, 162 caregivers of children 0 to 36 months of age were recruited from a pediatric hospital inpatient and outpatient facility. The EQ-TIPS; Ages and Stages Questionnaire; face, legs, activity, cry, and consolability; and dietary information were completed by all caregivers. The distribution of dimension scores, Spearman's correlation, analysis of variance, and regression analysis were used to explore the validity of the EQ-TIPS. RESULTS: The descriptive system of the EQ-TIPS was generally well understood and accepted by caregivers. The correlation coefficients for concurrent validity were significant and moderate for pain and weak and significant for the other dimensions hypothesized to correlate. Known groups were compared and inpatients had a significantly higher report of pain (χ2 = 7.47, P = .024) and more problems reported across all EQ-TIPS dimensions (recorded on the level sum score) (Kruskal Wallis H = 3.809, P = .05) and reported significantly worse health on the visual analog scale (Kruskal Wallis H = 15.387, P < .001). There were no age-related differences except for a lower report of problems with movement in the 0- to 12-month group (χ2 = 10.57, P = .032). CONCLUSION: The Afrikaans version of the EQ-TIPS is well understood and accepted by caregivers and valid for use with children aged 0 to 36 months in South Africa.

RESUMEN

OBJECTIVES: The aim of this study was to determine the validity and reliability of the EQ-5D-Y-3L interviewer-administered (IA) version in South African children aged 5-7-years compared to 8-10-years. METHODS: Children aged 5-10-years (n = 388) were recruited from healthcare facilities, schools for learners with special educational needs and mainstream schools across four known condition groups: chronic respiratory illnesses, functional disabilities, orthopaedic conditions and the general population. All children completed the EQ-5D-Y-3L IA, Moods and Feelings Questionnaire (MFQ), Faces Pain Scale-Revised (FPS-R) and a functional independence measure (WeeFIM) was completed by the researcher. Cognitive debriefing was done after the EQ-5D-Y-3L IA to determine comprehensibility. Test-retest of the EQ-5D-Y-3L IA was done 48 h later and assessed using Cohen's kappa (k). RESULTS: Results from children aged 5-7-years (n = 177) and 8-10-years (n = 211) were included. There were significantly higher reports of problems in the Looking After Myself dimension in the 5-7-year-olds (55%) compared to the 8-10-year-olds (28%) (x2 = 31.021; p = 0.000). The younger children took significantly longer to complete the measure (Mann-Whitney U = 8389.5, p < 0.001). Known-group validity was found at dimension level with children receiving orthopaedic management reporting more problems on physical dimensions across both age-groups. Convergent validity between Looking After Myself and WeeFIM items of self-care showed moderate to high correlations for both age-groups with a significantly higher correlation in the 8-10-year-olds for dressing upper (z = 2.24; p = 0.013) and lower body (z = 2.78; p = 0.003) and self-care total (z = 2.01; p = 0.022). There were fair to moderate levels of test-retest reliability across age-groups. CONCLUSION: The EQ-5D-Y-3L IA showed acceptable convergent validity and test-retest reliability for measuring health in children aged 5-7-years. There was more report of problems with the dimension of Looking After Myself in the 5-7-year group due to younger children requiring help with dressing, including buttons and shoelaces due to their developmental age, rather than their physical capabilities. Therefore, it may be useful to include examples of age-appropriate dressing tasks. There was further some reported difficulty with thinking about the dimensions in the younger age-group, most notably for Usual Activities which includes a large number of examples. By decreasing the number of examples it may reduce the burden of recall for the younger age-group.

RESUMEN

Background: Considering the high burden of disease in young children measurement of Health-Related Quality of Life is needed to evaluate the burden of morbidity. This study aims to report on the validity and reliability of the isiXhosa EuroQol Toddler and Infant Populations (EQ-TIPS) measure for South Africa. Methods: A sample of 181 caregivers of children 0-36 months were recruited from a hospital in-patient (inpt) and outpatient (outpt) facility and crèches. The EQ-TIPS, Ages and Stages Questionnaire (ASQ), Faces, Leg, Activity, Cry, Consolability (FLACC) and dietary information were administered at baseline. EQ-TIPS was administered one week later in crèche children for test-retest reliability. Results: Known groups showed significant differences for pain (X2=37.21, p<0.001), and EQ-TIPS level sum score (KWH=25.9, p<0.001) between health groups. The Visual Analogue Scale was unable to discriminate general health between groups (KW-H=3.92, p=0.141). Concurrent validity was weak to moderate and significant for all dimensions hypothesised to correlate. There was significant fair to moderate test-retest reliability for EQ-TIPS dimensions of movement, play, pain and eating. Conclusion: The isiXhosa EQ-TIPS is valid and reliable for very young children in South Africa and we suggest that it be included in the assessment of children with health conditions within this context.

RESUMEN

OBJECTIVES: This study aimed to compare the performance of the EQ-5D-Y 3-level version (Y-3L) and the expanded 5-level version, the EQ-5D-Y 5-level version (Y-5L). METHODS: Children or adolescents with an acute or chronic health condition and from the general population completed the Y-5L and Y-3L self-report questionnaires. The performance of the Y-5L and Y-3L was determined by comparing feasibility, redistribution of dimension responses, discriminatory power, validity, and test-retest reliability. RESULTS: A total of 550 children/adolescents completed baseline measures and 173 completed repeat measures. The ceiling effect decreased by 15% from the Y-3L to Y-5L. Informativity of dimensions improved by 0.094 on the Y-5L. There was a range of 4% to 9% inconsistent responses moving from the Y-3L to Y-5L. Convergent validity of the visual analog scale and Y-3L and Y-5L dimensions was similar and weak to moderate (rs range 0.18-0.38) but similar and strong on paired Y-3L and Y-5L dimensions: Kendall tau B (range 0.69-0.80) and gamma (range 0.92-0.98). The Y-5L and Y-3L showed moderate to substantial agreement for test-retest reliability across dimensions and visual analog scale scores in stable chronic health conditions and fair agreement for the general population. CONCLUSION: The Y-5L is a valid, reliable extension of the Y-3L for children or adolescents across health conditions and healthy children/adolescents. The expanded levels reduced the ceiling effect. The relative informativity of report across dimensions increased on the Y-5L compared with the Y-3L with retention of the evenness of reporting. The convergent validity and test-retest reliability of the Y-5L was comparable with the Y-3L.

RESUMEN

(1) Background: An estimated 78% of South African children aged 9-10 years have not mastered basic reading, therefore potentially excluding them from self-reporting on health-related outcome measures. Thus, the aim of this study was to compare the performance of the EQ-5D-Y-3L self-complete to the newly developed interviewer-administered version in children 8-10 years. (2) Methods: Children (n = 207) with chronic respiratory illnesses, functional disabilities, orthopaedic conditions and from the general population completed the EQ-5D-Y-3L self-complete and interviewer-administered versions, Moods and Feelings Questionnaire (MFQ) and Faces Pain Scale-Revised (FPS-R). A functional independence measure (WeeFIM) was completed by the researcher. (3) Results: The 8-year-olds had significantly higher missing responses (x2 = 14.23, p < 0.001) on the self-complete version. Known-group and concurrent validity were comparable across dimensions, utility and VAS scores for the two versions. The dimensions showed low to moderate convergent validity with similar items on the MFQ, FPS-R and WeeFIM with significantly higher correlations between the interviewer-administered dimensions of Mobility and WeeFIM mobility total (z = 1.91, p = 0.028) and Looking After Myself and WeeFIM self-care total (z = 3.24, p = 0.001). Children preferred the interviewer-administered version (60%) (x2 = 21.87, p < 0.001) with 22% of the reasons attributed to literacy level. (4) Conclusions: The EQ-5D-Y-3L interviewer-administered version is valid and reliable in children aged 8-10 years. The results were comparable to the self-complete version indicating that versions can be used interchangeably.
