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.

Comparative Study
Content comparison of health-related quality of life (HRQOL) instruments based on the international classification of functioning, disability and health (ICF).
The increasing recognition of the patient perspective and, more specifically, functioning and health, has led to an impressive effort in research to develop concepts and instruments to measure them. Health-Related Quality of Life (HRQOL) and the International Classification of Functioning Disability and Health (ICF) represent two different perspectives from which to look at functioning and health. Therefore, it is expected that both will often be used concurrently in clinical practice, research and health reporting. ⋯ Only four of the six instruments address environmental factors. The ICF proved highly useful for the comparison of HRQOL instruments. The comparison of selected HRQOL instruments may provide clinicians and researchers with new insights when selecting health-status measures for clinical studies.

This study aimed to validate the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30, English version 3.0) in Singaporean cancer patients. ⋯ This study provides preliminary evidence for the validity and reliability of the EORTC QLQ-C30 in English-speaking Singaporean cancer patients.

The Lung Cancer Symptom Scale (LCSS), a site-specific health-related quality of life measure for patients with lung cancer, was originally developed using a Visual Analogue Scale (VAS) format. However, the VAS format is not readily compatible with data management and software programs using scanning. The primary aim of this study was to evaluate the convergence of ratings obtained with a Numerical Rating Scale (NRS), with an 11-pt response category format, to those obtained with a VAS format. The intent was to determine the degree of agreement between two formats to generalize the existing psychometric properties for the original measure to the new presentation. ⋯ Overall, the NRS format for the LCSS suitable for scanning has good feasibility, reliability (internal consistency), and convergent validity. The complete set of concordance evaluation measures supports the reproducibility of VAS scores by NRS scores, particularly for the two summary scores.
