Review Comparative Study
Comparison of the minimally important difference for two health state utility measures: EQ-5D and SF-6D.
The SF-6D and EQ-5D are both preference-based measures of health. Empirical work is required to determine what the smallest change is in utility scores that can be regarded as important and whether this change in utility value is constant across measures and conditions. ⋯ There is evidence that the MID for these two utility measures are not equal and differ in absolute values. The EQ-5D scale has approximately twice the range of the SF-6D scale. Therefore, the estimates of the MID for each scale appear to be proportionally equivalent in the context of the range of utility scores for each scale. Further empirical work is required to see whether or not this holds true for other utility measures, patient groups and populations.

We undertook to translate and cross-culturally adapt the Functional Assessment of Cancer Therapy-Breast (FACT-B) scale into Korean and to evaluate its reliability and validity. The translation procedure followed the standard Functional Assessment of Chronic Illness Therapy translation methodology. A total of 201 breast cancer patients (mean age, 43.87 years) were studied for psychometric properties of the FACT-B scale. ⋯ The FACT-B scale also demonstrated good convergent and divergent validity when correlated with the shortened forms of the Profile of Mood States and the Functional Living Index-Cancer (FLIC). We can now evaluate the Quality of Life (QoL) of Korean breast cancer patients using this reliable and valid instrument. Nevertheless our study has the limitation that it did not evaluate the sensitivity to the changes of the patients' QoL in the long term follow-up, and we will supplement it in our further study.

The aim of this 12-month prospective study was to compare reports describing the health-related quality of life (HRQL) of children with Juvenile idiopathic arthritis (JIA) obtained from parents and children, to investigate the extent to which the children's HRQL changed over a 12-month period, and to describe the relationship between children's HRQL, and their experience of pain and use of pain coping strategies. Fifty-four children aged 8-18 years with JIA and their parents completed standard questionnaires assessing children's HRQL, pain intensity, and pain coping strategies at baseline, 6 months, and 12 months. ⋯ Consistent with the Biobehavioural Model of Pain, there was a significant negative relationship between children's HRQL and their experience of pain. However, there was little evidence that pain coping strategies mediated the relationship between children's experience of pain and their HRQL.

To describe the initial results of the Child Health Ratings Inventory (CHRIs), 20-item generic health-related quality of life (HRQL) instrument and the 10-item disease-specific (DS) module, the Disease Specific Impairment Inventory-Hematopoietic Stem Cell Transplantation (DSII-HSCT), for children and adolescents, ages 5-18 years and their parents following HSCT. ⋯ results suggest that the CHRIs generic core and its DSII-HSCT module is a promising measure of HRQL after pediatric HSCT. Although parent and child reports were moderately correlated and revealed complementary results, the unique perspectives of both raters provide a more complete picture of HRQL. Longitudinal application is underway to further characterize the measurement properties of the CHRIs and to determine the instrument's responsiveness and sensitivity to change over time in this vulnerable population.
