The objective of this study was to evaluate the reliability and construct validity of the Chinese parent form (PF50) and child form (CF87) of the Child Health Questionnaire (CHQ). ⋯ Our findings suggest that the Chinese CHQ-PF50 and CHQ-CF87 are robust and sufficiently reliable for group comparisons and perhaps also for use in other Chinese populations.

Comparative Study
Ethnic differences in quality of life in adolescents among Chinese, Malay and Indians in Singapore.
Health-related quality of life in adolescents and ethnic and cultural differences are not well characterized. We used the Quality of Life Questionnaire for Adolescents (QOLQA) to examine ethnic differences in reported QOL scores among Chinese, Malay and Indian ethnicities in Singapore. ⋯ Significant ethnic differences in reported adolescent quality of life among Chinese, Malays and Indians in Singapore that are independent of socioeconomic and health status suggest important cultural differences.

Venous leg ulcers are an important source of morbidity in society. Measuring the impact of leg ulcers on quality of life is important within clinical and economic evaluations. In this study we report a validation study of the leg ulcer disease specific Hyland questionnaire and compare its discriminative and responsive characteristics to general health quality of life measures: the SF-12 and EQ-5D. ⋯ SF-12 and EQ-5D are suitable for exploring dimensions of health related quality of life in people with chronic venous leg ulceration. The responsiveness to healing of the Hyland questionnaire is unclear. We would recommend the use of generic instruments for the measurement of HRQoL in patients with venous leg ulcers.

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.
