The PedsQL™ (Pediatric Quality of Life Inventory™) is a modular instrument designed to measure health-related quality of life and disease-specific symptoms. The PedsQL™ Cognitive Functioning Scale was developed as a brief generic symptom-specific instrument to measure cognitive functioning. The objective of the present study was to determine the feasibility, reliability, and validity of the PedsQL™ Cognitive Functioning Scale in pediatric liver transplant recipients. ⋯ The results demonstrate the feasibility, reliability, discriminant, construct, and concurrent validity of the PedsQL™ Cognitive Functioning Scale in pediatric liver transplant recipients.

The purpose of this study was to translate the Oxford Hip Score (OHS) into Italian and to evaluate the psychometric properties by testing the feasibility, internal consistency, reproducibility, construct validity, and responsiveness in patients with hip osteoarthritis (OA). ⋯ The Italian OHS questionnaire is valid, reliable, and responsive for use in Italian patients with symptomatic hip OA receiving hyaluronate injections.

The objective of this study was to validate the Spanish version of the SMiLE (Schedule for Meaning in Life Evaluation). The SMiLE is a respondent-generated instrument: respondents are first asked to list three to seven areas, which provide meaning to their lives, and then to rate their current satisfaction with the listed areas, as well as the individual importance of each one. Indices of total weighting (IoW), total satisfaction (IoS), and total weighted satisfaction (IoWS) are calculated. ⋯ The results support the validity of the Spanish version of the SMiLE as an instrument for assessing meaning in life.

We translated the S-QoL into the Chinese (Taiwan) language and evaluated the score distributions of the translated S-QoL in terms of ceiling/floor effect, internal consistency, test-retest reliability, and convergent and discriminant validity. To ensure conceptual and semantic equivalence of the S-QoL, the researchers performed both forward translation and back translation, consulted professionals, and completed a pilot trial on college students. Forty-one patients with schizophrenia were recruited. ⋯ The convergent validities were supported by satisfactory correlations among subscales measuring related constructs of the translated S-QoL and those of the SQLS-R4, WHOQoL-BREF, and RESE (r = 0.36-0.82, P < 0.05 to <0.01). Discriminant validity was demonstrated between groups with different numbers of episodes and hospitalization. The S-QoL Chinese (Taiwan) version was found to have good psychometrics and is suggested as a feasible choice of disease-specific measure for capturing HRQoL in patients with schizophrenia.

To assess the patterns of, and trends over time in, health-related quality of life (HRQL) reporting in randomized controlled trials (RCTs). ⋯ Current practice of reporting HRQL outcomes in RCTs remains highly variable, both with regard to quality of reporting and the patterns of data analysis and presentation. This variation presents challenges for clinicians to apply these data in clinical practice. Consistent reporting practices, which are interpretable by clinicians, are required, as are processes to achieve this consistency in future reports.
