The aim of the study was to develop a cross-cultural adaptation and to evaluate the validity and reliability of a Spanish version of the Quality of Life in Late-Stage Dementia (QUALID) scale. ⋯ Our evaluation of the psychometric properties of the Spanish version of the QUALID indicates that it is a reliable and valid instrument with an adequate capacity to distinguish between different clinical status.

This study was intended to present evidence for the reliability and validity of a Greek translation of the Medical Outcomes Study-HIV Health Survey (MOS-HIV). ⋯ The Greek version of the MOS-HIV had good reliability and validity among patients with AIDS. Convergent and concurrent validity were generally confirmed. The MOS-HIV may be useful in assessing health-related quality of life in AIDS patients in Greece. Further research is needed for the evaluation of the Greek version of the MOS-HIV responsiveness to changes over time.

To develop and validate a composite score based on clinically meaningful events (CMEs) for the opioid-related symptom distress scale (OR-SDS) that would be appropriate for use in postoperative clinical trials. ⋯ The OR-SDS CME-based composite score demonstrates evidence of construct validity and appears appropriate for use in evaluating patients' opioid-related side effect burden in future postoperative clinical trials.

Comparative Study
The comparative responsiveness of the EQ-5D and SF-6D to change in patients with inflammatory arthritis.
Comparative evidence regarding the responsiveness of the EQ-5D and SF-6D in arthritis patients is conflicting and insufficient across the range of disease severity. We examined the comparative responsiveness of the EQ-5D and SF-6D in cohorts of patients with early inflammatory disease through to severe rheumatoid arthritis (RA). ⋯ The comparative responsiveness of the EQ-5D and SF-6D differs according to the direction of change. The level of mean change of the EQ-5D relative to the SF-6D has implications for cost-effectiveness analysis. Use of the SF-6D in patients with severe progressive disease may be inappropriate.

The use of global health items permits an efficient way of gathering general perceptions of health. These items provide useful summary information about health and are predictive of health care utilization and subsequent mortality. ⋯ Two dimensions representing physical and mental health underlie the global health items in PROMIS. These global health scales can be used to efficiently summarize physical and mental health in patient-reported outcome studies.
