Multicenter Study
The Italian version of the Pain Beliefs and Perceptions Inventory: cross-cultural adaptation, factor analysis, reliability and validity.
To create an Italian version of the Pain Beliefs and Perceptions Inventory (PBAPI-I) and evaluate its psychometric properties. ⋯ The PBAPI-I has good psychometric properties that replicate those of other versions.

Multicenter Study
Development and validation of the functional assessment of chronic illness therapy treatment satisfaction (FACIT TS) measures.
To develop and validate a new functional assessment of chronic illness therapy (FACIT) measure of satisfaction with treatment for chronic illnesses such as cancer and HIV/AIDS. ⋯ The two instruments generated here offer a new way to assess several key dimensions of patient satisfaction with treatment, especially for people with lung cancer.

Multicenter Study
Validity, reliability and discriminative capacity of an electronic quality of life instrument (Pelican) for childhood asthma in the Netherlands.
To assess psychometric properties of the Pelican instrument, an online Dutch self-administered Quality of Life instrument for childhood asthma for scientific and clinical use. ⋯ The psychometric properties of the Pelican instrument were acceptable in Dutch paediatric asthma patients between 6 and 12 years old.

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.

Multicenter Study Clinical TrialMeasuring outcomes that matter to face-lift patients: development and validation of FACE-Q appearance appraisal scales and adverse effects checklist for the lower face and neck.
The FACE-Q is a new patient-reported outcome instrument to evaluate a range of outcomes for patients undergoing any type of facial cosmetic operation, minimally invasive cosmetic procedure, or facial injectable. This article describes the development and validation of FACE-Q scales relevant to face-lift patients. ⋯ The five FACE-Q appearance appraisal scales were found to be clinically meaningful, reliable, valid, and responsive to clinical change. These findings were supported by Rasch measurement theory analysis (e.g., overall chi-square values of p ≥ 0.18; Person Separation Index ≥ 0.88). Responsiveness analyses showed that patient scores for facial appearance improved significantly after treatment (p < 0.001); changes in scores were associated with moderate effect sizes (range effect size, 0.40 to 0.79; range standardized response mean, 0.37 to 0.69). Traditional psychometric statistics provided further support (e.g., Cronbach's alpha values ≥ 0.94) CONCLUSIONS:: The FACE-Q appearance appraisal scales are scientifically sound and clinically meaningful and can be used with the adverse effects checklist to measure patient-reported outcomes following a face lift.
