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.

Randomized Controlled Trial
Testing the measurement equivalence of paper and interactive voice response system versions of the EORTC QLQ-C30.
The objective of this study was to evaluate the measurement equivalence of an interactive voice response system (IVRS) version and the original paper-based version of the EORTC QLQ-C30. ⋯ This analysis provides evidence that the scores obtained from the IVRS version of the QLQ-C30 are equivalent to those obtained with the original paper version except for the insomnia and appetite loss items.

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 purpose of this study was to translate the Foot Function Index (FFI) into Italian, to perform a cross-cultural adaptation and to evaluate the psychometric properties of the Italian version of FFI. ⋯ The Italian version of the FFI showed satisfactory psychometric properties in Italian patients with foot and ankle diseases. Further testing in different and larger samples is required in order to ensure the validity and reliability of this score.
