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.

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.

Mindfulness has emerged as an important health concept based on evidence that mindfulness interventions reduce symptoms and improve health-related quality of life. The objectives of this study were to systematically assess and compare the properties of instruments to measure self-reported mindfulness. ⋯ Current mindfulness scales have important conceptual differences, and none can be strongly recommended based solely on superior psychometric properties. Important limitations in the field are the absence of qualitative evaluations and accepted external referents to support construct validity. Investigators need to proceed cautiously before optimizing any mindfulness intervention based on the existing scales.
