The Patient-Reported Outcomes Measurement Information System (PROMIS (®) ) is a US National Institutes of Health initiative that has produced self-reported item banks for physical, mental and social health. ⋯ The PROMIS-ICF mapped items provide a basis for users to evaluate the ICF-related content of specific PROMIS instruments and to select PROMIS instruments in ICF-based measurement applications.

In the fear-avoidance model (FAM) of chronic pain, pain-related fear is one of the most prominent predictors of negative adjustment outcomes. While existing data point to the effects of anxiety sensitivity, pain hypervigilance, and pain catastrophizing on pain-related fear, the nature of their multivariate relationships remains unclear. This study explored the possible mediating role of pain hypervigilance in the relationship of anxiety sensitivity and pain catastrophizing with pain-related fear, and their effects on quality of life (QoL) outcomes within the FAM framework. ⋯ These cross-sectional analyses gave results consistent with pain hypervigilance, mediating the relationship of pain catastrophic cognition and anxiety sensitivity with pain-related fear. The net suppression effects of pain catastrophizing point to anxiety sensitivity, enhancing the effect of pain catastrophic cognition on pain hypervigilance. These findings elucidate how the interdependence of dispositional factors might influence pain adjustment and functioning.

Comparative Study
Assessing quality of life in patients with prostate cancer: a systematic and standardized comparison of available instruments.
The objective was to obtain a standardized evaluation of available prostate cancer-specific quality of life instruments used in patients with early-stage disease. ⋯ Current evidence supports the choice of EPIC, PORPUS or PC-QoL. Attribute-specific EMPRO results facilitate selecting the adequate instrument for every purpose. For longitudinal studies or clinical trials, where responsiveness is the priority, EPIC or PC-QoL should be considered. We recommend the PORPUS for economic evaluations because it allows cost-utility analysis, and EPIC short versions to minimize administration burden.

The purpose of the study was to compare psychometric properties of the EQ-5D-5L (5L) and the EQ-5D-3L (3L) health outcomes assessment instruments in patients with hepatitis B in China. ⋯ The EQ-5D-5L was more suitable than the EQ-5D-3L in the patients with hepatitis B in China.

Comparative Study Clinical Trial
Psychometric properties of quality of life and health-related quality of life assessments in people with multiple sclerosis.
There is substantial interest in testing interventions for improving quality of life (QOL) and health-related quality of life (HRQOL) in people with multiple sclerosis (MS). Yet, there is limited research on the psychometric properties of QOL [e.g., Satisfaction with Life Scale (SWLS), Leeds MS Quality of Life Scale (LMSQOL)] and HRQOL [e.g., Short Form 12 Health Survey (SF-12) and Multiple Sclerosis Impact Scale-29 (MSIS-29)] measures in this population. Such research is important for designing and interpreting interventions. We examined the test-retest reliability, measurement error, and interpretability of QOL (i.e., SWLS and LMSQOL) and HRQOL (i.e., SF-12 and MSIS-29) measures over 6 months in people with MS. ⋯ We provide novel data for helping researchers and clinicians select and interpret QOL and HRQOL measures and scores for interventions among people with MS. Such information will better inform our understanding of intervention effectiveness.
