The objective of this study was to test the reliability and validity of the Japanese version of the European Organization for Research and Treatment of Cancer (EORTC) Colorectal Cancer-Specific Quality of Life Questionnaire (QLQ-CR38). ⋯ These preliminary results suggest that the Japanese EORTC QLQ-CR38 may be a reliable and valid supplementary measure of quality of life in colorectal cancer patients.

Psychometric properties of the WHODASII in rehabilitation patients.
To evaluate function and disability, the WHO has developed the WHO Disability Assessment Schedule II (WHODASII), an instrument arising from the same conceptual basis as the International Classification of Functioning, Disability, and Health (ICF). ⋯ The WHODAS II (German version) is a useful instrument for measuring functioning and disability in patients with musculoskeletal diseases, internal diseases, stroke, breast cancer, and depressive disorder. The results of this study support the reliability, validity, dimensionality, and responsiveness of the German version of the WHODASII. However, the reproducibility in test-retest samples of stable patients, as well as the question to what extent a summary score can be constructed, requires further investigation.

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.

Summarize the Patient Assessment of Upper GastroIntestinal Disorders-Quality of Life (PAGI-QOL) development and provide results on its reliability and validity from the international psychometric validation in dyspepsia, GastroEsophageal Reflux Disease (GERD), and gastroparesis. ⋯ The PAGI-QOL is a valid and reliable instrument assessing quality of life in patients with dyspepsia, GERD, or gastroparesis.

Describe the development and evaluation of a new self-report instrument, the patient assessment of upper gastrointestinal disorders-symptom severity index (PAGI-SYM) in subjects with gastroesophageal reflux disease (GERD), dyspepsia, or gastroparesis. ⋯ Results suggest the PAGI-SYM, a brief symptom severity instrument, has good reliability and evidence supporting construct validity in subjects with GERD, dyspepsia, or gastroparesis.
