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.

The aim of this study was to develop and evaluate the internal consistency and construct validity of a Korean version of the Caregiver Quality of Life Index-Cancer (CQOLC-K). ⋯ These findings support the internal consistency reliability and construct validity of the Korean version of the CQOLC-K. The instrument can be used to measure quality of life in caregivers of cancer patients in clinical and epidemiological research.

Few comprehensive systems are available for assessing and reporting the overall health of preschool children. ⋯ The HSCS-PS is readily accepted, quick to complete, widely applicable and provides a multi-dimensional description of health status. Preliminary assessments of reliability and validity are promising. The HSCS-PS can discriminate across populations by birthweight and shows strong relationships with standardized psychometric measures in comparable domains. It can pro- vide a summary profile of functional limitations in various populations of pre-school children in a consistent manner across programs and in different settings.

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.
