The objective of the present study was to translate the Kidney Disease Quality of Life -- Short Form (KDQOL-SF 1.3) questionnaire into Portuguese to adapt it culturally and validate it for the Brazilian population. The KDQOL-SF was translated into Portuguese and back-translated twice into English. Patient difficulties in understanding the questionnaire were evaluated by a panel of experts and s...

The validity of an accelerometric system (Myotest©) for assessing vertical jump height, vertical force and power, leg stiffness and reactivity index was examined. 20 healthy males performed 3×"5 hops in place", 3×"1 squat jump" and 3× "1 countermovement jump" during 2 test-retest sessions. The variables were simultaneously assessed using an accelerometer and a force platform at a frequency of 0...

Objective: The purpose of this study was to develop a career-orientation scale for public health nurses (PHNs) and to validate the scale. Methods: Self-administered questionnaires were sent to 7170 PHNs in 10 prefectures. A retest survey was sent to 252 participants. Results: The valid responses from 2003 PHNs in the first survey were analyzed for major factors by varimax rotation. The analysis...

This study was conducted to develop a scale to measure knowledge about hypertension among Turkish adults. The Hypertension Knowledge-Level Scale (HK-LS) was generated based on content, face, and construct validity, internal consistency, test re-test reliability, and discriminative validity procedures. The final scale had 22 items with six sub-dimensions. The scale was applied to 457 individuals...

Background The Mild Cognitive Impairment Questionnaire (MCQ) is a 13-item measure that assesses health-related quality of life (HRQoL) in people with mild cognitive impairment (PWMCI); it has two domains assessing the emotional and practical effects. Objective The aim of this study was to assess the psychometric properties of the MCQ. Design This is a longitudinal questionnaire-based study....

We carry out a computational study of optical properties of two novel 5,6-difluorobenzo[c][1,2,5]-thiadiazole-based polymers, PFBT-T20TT and PFBT-T12TT, to elucidate the surprisingly superior performance of polymer solar cells based on the former, when it differs from the latter only in the alkyl side chains. Density Functional Theory (DFT) based geometry optimization at the B3LYP/6-31G(d) leve...

Aim Food Allergy may have an impact on socioeconomic (SE) aspects of life. The Europrevall study (EU FP6, 2005-2009) developed and validated a SE questionnaire to measure the direct, indirect and intangible costs of food allergy. This measure takes up to 1 hour to complete as participants are required to respond to 70 to 170 questions, depending on response choice. We aimed to develop a brief, ...

OBJECTIVES There currently exists no reliable or validated tool for the assessment of exercise-related injuries in older adults. The purpose was to develop and evaluate the psychometric properties of a questionnaire to measure exercise-related injury in older adults participating in supervised exercise programmes. DESIGN The study utilised a repeated survey design. SETTING The study took pl...

The purpose of this study was to analyze the effects of different vibration magnitudes via feet on the number of repetitions performed, mean velocity, and perceived exertion during a set of elbow-extension exercise to failure (70% 1 repetition maximum [1RM] load). Twenty recreationally active students (14 men and 6 women) performed, in 3 different days, 1 elbow-extension set applying randomly 1...

An astronomical or navigational almanac can best be thought of as a device for connecting an observer with celestial objects. For an observer with a known position and time the almanac allows the observer to identify the celestial objects. Conversely, if the observer knows what objects he is observing and when, the almanac allows him to determine his position. In either case, knowledge of the t...
