Multicenter Study
Validation of a Quality of Life Questionnaire for Bronchiectasis: psychometric analyses of the Spanish QOL-B-V3.0.
Bronchiectasis is a chronic disease, leading to worsening of health-related quality of life. This study evaluated the psychometric properties of a new patient-reported outcome for non-cystic fibrosis bronchiectasis, the Quality of Life Questionnaire Bronchiectasis, translated into Spanish (QOL-B-Sp-V3.0). ⋯ The QOL-B-Sp-V3.0 questionnaire demonstrated strong reliability and validity. Scores were reproducible after 2 weeks, and it discriminated between patients who varied in severity and was responsive to changes related to exacerbation.

Comparative Study
Psychometric properties of the PROMIS ® pediatric scales: precision, stability, and comparison of different scoring and administration options.
The objectives of the present study are to investigate the precision of static (fixed-length) short forms versus computerized adaptive testing (CAT) administration, response pattern scoring versus summed score conversion, and test-retest reliability (stability) of the Patient-Reported Outcomes Measurement Information System (PROMIS(®)) pediatric self-report scales measuring the latent constructs of depressive symptoms, anxiety, anger, pain interference, peer relationships, fatigue, mobility, upper extremity functioning, and asthma impact with polytomous items. ⋯ The study provides further information on the psychometric properties of the PROMIS pediatric scales and extends the previous IRT analyses to include precision estimates of dynamic versus static administration, test-retest reliability, and validity of administration across groups. Both the positive and negative aspects of using CAT versus short forms are highlighted.

Comparative Study
Validation and comparison of 15-D and EQ-5D-5L instruments in a Spanish Parkinson's disease population sample.
To contribute to the ongoing discussion on the choice of a preference-based health-related quality of life (HRQoL) instrument to be used in cost-effectiveness analysis by studying and comparing the validity, sensitivity and relative efficiency of 15-D and EuroQol 5D 5L (EQ-5D-5L) in a Spanish Parkinson's disease (PD) population sample. ⋯ 15-D and EQ-5D-5L are showed to be valid and sensitivity generic HRQoL measures in Spanish PD patients with both instruments showing similar HRQoL dimension coverage and ceiling/floor effects. The 15-D has better efficiency and greater sensitivity to detect clinical changes in PD severity of the symptoms meanwhile the EQ-5D-5L is better to detect clinical HRQoL changes. Additionally, the EQ-5D-5L questionnaire requires less time than 15-D to be administered, and it might be more appropriate for studies conducted in Spain, since a country-specific "value set" is available for this instrument and not for the 15-D.

Sarcoidosis is a multisystem disease that can negatively impact health-related quality of life (HRQL) across generic (e.g., physical, social and emotional wellbeing) and disease-specific (e.g., pulmonary, ocular, dermatologic) domains. Measurement of HRQL in sarcoidosis has largely relied on generic patient-reported outcome tools, with little disease-specific measures available. The purpose of this paper is to present the development and testing of disease-specific item banks and short forms of lung, skin and eye problems, which are a part of a new patient-reported outcome (PRO) instrument called the sarcoidosis assessment tool. ⋯ Several new sarcoidosis-specific PROs were developed and tested using IRT approaches. These new measures can advance more precise and targeted HRQL assessment in sarcoidosis clinical trials and clinical practice.

Review Meta Analysis Comparative Study
Reporting of health-related quality of life (HRQOL) data in oncology trials: a comparison of the European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) and the Functional Assessment of Cancer Therapy-General (FACT-G).
The inclusion of patient-reported outcome (PRO) instruments to record patient health-related quality of life (HRQOL) data has virtually become the norm in oncology randomised controlled trials (RCTs). Despite this fact, recent concerns have focused on the quality of reporting of HRQOL. The primary aim of this study was to evaluate the quality of reporting of HRQOL data from two common instruments in oncology RCTs. ⋯ The majority of oncology RCTs has shortcomings in terms of reporting HRQOL data when assessed against regulatory and methodology guidelines. These limitations will need to be addressed if HRQOL data are to be used to successfully support clinical decision-making, treatment options and labelling claims in oncology.
