Multicenter Study
Cognitive interviewing of the US National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE).
The National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) is a library of question items that enables patient reporting of adverse events (AEs) in clinical trials. This study contributes content validity evidence of the PRO-CTCAE by incorporating cancer patient input of the relevance and comprehensiveness of the item library. ⋯ This study provides evidence confirming comprehension of the US English language versions of items in the PRO-CTCAE library for measuring symptomatic AEs from the patient perspective within the context of cancer treatment. Several minor changes were made to the items to improve item clarity, comprehension, and ease of response judgment. This study helps to establish the content validity of PRO-CTCAE items for patient reporting of AEs during cancer treatment.

The Overactive Bladder Symptom Score (OABSS) is comprised of 4 items with a single total score for quantification of OAB symptoms and has been reported as sensitive to treatment-related changes. The aim of this study was to assess the psychometric properties of the Korean version in patients with OAB symptoms. ⋯ With good psychometric properties and responsiveness, the Korean version of the OABSS may offer researchers and clinicians a valid and reliable measure for the assessment of OAB symptoms in the Korean population.

Comparative Study
PROMIS® Parent Proxy Report Scales for children ages 5-7 years: an item response theory analysis of differential item functioning across age groups.
The objective of the present study is to describe the extension of the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS(®)) pediatric parent proxy-report item banks for parents of children ages 5-7 years, and to investigate differential item functioning (DIF) between the data obtained from parents of 5-7-year-old children with the data obtained from parents of 8-17 year-old children in the original construction of the scales. ⋯ The study confirms that most of the items in the PROMIS parent proxy-report item banks can be used with parents of children ages 5-7. It is anticipated that these new scales will have application for younger pediatric populations when pediatric self-report is not feasible.

The assessment of pain sensation and quality is a key component in understanding the experience of individuals with chronic pain. This study evaluated the factor structure of the patient-reported outcome measurement information system (PROMIS) pain quality item bank. ⋯ Further research is needed to evaluate the psychometric characteristics of the derived scales based on their factor scores.

The aim of this study was to validate the Chinese version of the Summated Xerostomia Inventory (SXI). ⋯ This study provided preliminary evidence concerning validity and reliability of the Chinese version of the SXI. The results provide initial evidence that the SXI may be a useful tool for the mainland Chinese xerostomia patients for both clinical and epidemiologic researches.
