Randomized Controlled TrialReliability, Validity and Responsiveness of the EQ-5D-5L in Assessing and Valuing Health Status in Adolescents and Young Adults with Posttraumatic Stress Disorder: a Randomized Controlled Trail.
To validate the EQ-5D-5L health-related quality of life (HrQoL) questionnaire in adolescents and young adults with posttraumatic stress disorder (PTSD) after sexual and/or physical abuse. We used data from a randomized controlled trial of 87 participants with PTSD aged 14-21 years. The discriminative ability was evaluated by comparing participants scores on the descriptive system of the EQ-5D-5L with general population scores. ⋯ Discriminative ability, test-retest reliability and construct validity of the EQ-5D-5L were good, whereas the responsiveness was rather weak. Nevertheless, the EQ-5D-5L can be used to measure HrQoL in adolescents and young adults with PTSD.

Randomized Controlled Trial
An Initial Psychometric Evaluation of the Pain Concepts Questionnaire in a Low-SES Setting.
The examination of pain beliefs for chronic pain assessment and treatment has been a growing area of interest. A variety of questionnaires have been developed to assess pain beliefs, however, these questionnaires often require high levels of literacy and education. The pain concepts questionnaire (PCQ) was developed with literacy-adaptations to better evaluate pain beliefs in a low socioeconomic (SES) population. ⋯ PERSPECTIVE: This study is an initial evaluation of the psychometric properties of a new measure of chronic pain beliefs, the pain concepts questionnaire (PCQ). The PCQ is literacy-adapted and was assessed within a low-SES population. Psychometric proprieties of this measure were promising and could be useful in pain assessment and interventions.

Randomized Controlled TrialA psychometric evaluation of the Family Decision-Making Self-Efficacy Scale among surrogate decision-makers of the critically ill.
The purpose of this study was to report the psychometric properties, in terms of validity and reliability, of the Unconscious Version of the Family Decision-Making Self-Efficacy Scale (FDMSE). ⋯ This is the first known study to provide evidence for a two-factor structure for a modified, 11-item FDMSE. These dimensions represent treatment and palliation-related domains of family decision-making self-efficacy. The modified FDMSE is a valid and reliable instrument that can be used to measure family decision-making self-efficacy among surrogate decision-makers of the critically ill.

Randomized Controlled Trial Multicenter Study
Psychometric Validation of the Role Function Restrictive Domain of the Migraine Specific Quality-of-Life Questionnaire Version 2.1 Electronic Patient-Reported Outcome in Patients With Episodic and Chronic Migraine.
To assess the measurement properties of the Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) electronic patient-reported outcome (ePRO) Role Function-Restrictive (RFR) domain to evaluate the functional impact of migraine in patients with episodic (EM) or chronic migraine (CM) enrolled in clinical trials. ⋯ The MSQv2.1 ePRO RFR has sufficient reliability, validity, responsiveness, and appropriate interpretation standards for use in EM and CM clinical trials to assess the functional impact of migraine.

Randomized Controlled Trial Multicenter Study
Psychometric properties of four fear of falling rating scales in people with Parkinson's disease.
Fear of falling (FOF) is commonly experienced in people with Parkinson's disease (PD). It is a predictor of recurrent falls, a barrier to physical exercise, and negatively associated with health-related quality of life. A variety of rating scales exist that assess different aspects of FOF but comprehensive head-to-head comparisons of their psychometric properties in people with PD are lacking. The aim of this study was to evaluate the psychometric properties of four FOF rating scales in people with PD. More specifically, we investigated and compared the scales' data completeness, scaling assumptions, targeting, and reliability. ⋯ When assessing FOF in people with PD, the findings in the present study favoured the choice of FES-I or mSAFFE. However, FES-I was the only scale with ICC >0.90 which has been suggested as a minimum when using a scale for individual comparisons.
