The Pediatric Quality of Life Inventory-Cognitive Functioning Scale (PedsQLTM-CFS) was developed as a brief, general, symptom-specific tool to measure cognitive function. The 6-item PedsQL™ Cognitive Functioning Scale and PedsQL 3.0 Cancer Module answered 369 parents and 330 children with 5–18 years. Parents also completed Behavior Rating Inventory of Executive Function (BRIEF). The PedsQL™ Cognitive Functioning Scale evidenced excellent reliability (parent proxy-report α = 0.980/Fleiss Kappa: 0.794; children self-report α = 0.963/Fleiss Kappa: 0.790). Both child self-report and parent proxy-report PedsQL™ Cognitive Functioning Scale scores exhibited significant correlations with all parent-report BRIEF summary and subscale scores (p < .05). Both child self-report and parent proxy-report PedsQL™ Cognitive Functioning Scale scores exhibited significant correlations with PedsQL 3.0 Cancer Module total score and subscale scores (p < .05). The PedsQLTM-CFS can be used in high-risk populations with substantial to perfect reliability, both in regards to total/subcategory scores as well as in children with cancer. [ABSTRACT FROM AUTHOR]

The concept of occupational balance in adolescents is not clear enough. The current study aims at developing a valid and reliable scale to measure occupational balance in adolescents. We conducted online interviews with the participant adolescents via semi-structured interview forms. We applied the Davis technique twice to 10 expert panellists and the test form to 600 individuals. Two weeks later, we re-tested 153 of the participants. We then carried out item analysis to evaluate the internal consistency of the scale. We also conducted explanatory factor analysis (EFA) and confirmatory factor analysis (CFA) to examine the construct validity of the scale. The content validity index of the scale was found to be 0.986. EFA showed that the scale consisting of 27 items had a six-factor structure explaining 56.7% of the total variance. Model fit indices about the structure created by factor combination technique in CFA were CMIN/df = 2.135; RMSEA = 0.06; GFI = 0.866; NFI = 0.81, CFI = 0.887, TLI = 0.868; IFI = 0.89. The analysis to test the reliability of the scale resulted in ICC: 0.993 and Cronbach's alpha: 0.997. Pre-test and post-test analyses showed very strong correlational coefficients (p < 0.005). A-OBS is a valid and reliable scale consisting of 27 items and 4 sub-dimensions. It can be used in studies that will focus on occupational balance in healthy adolescents. It is the first occupational balance scale developed for adolescents in the occupational therapy literature. We recommend further studies to validate the scale and adapt it to different languages and cultures. [ABSTRACT FROM AUTHOR]
