Validation of the GENEA Accelerometer

A Validation Study of the Web-Based Physical Activity Questionnaire Active-Q Against the GENEA Accelerometer

BACKGROUND Valid physical activity assessment in epidemiological studies is essential to study associations with various health outcomes. OBJECTIVE To validate the Web-based physical activity questionnaire Active-Q by comparing results of time spent at different physical activity levels with results from the GENEA accelerometer and to assess the reproducibility of Active-Q by comparing two ad...

Classification Accuracy of the Wrist-Worn GENEA Accelerometer During Structured Activity Bouts: A Cross-Validation Study

Physical activity classification using the GENEA wrist-worn accelerometer.

INTRODUCTION Most accelerometer-based activity monitors are worn on the waist or lower back for assessment of habitual physical activity. Output is in arbitrary counts that can be classified by activity intensity according to published thresholds. The purpose of this study was to develop methods to classify physical activities into walking, running, household, or sedentary activities based on r...

Calibration of the GENEA accelerometer for assessment of physical activity intensity in children.

OBJECTIVES The purpose of the study was to establish activity intensity cut-points for the GENEA accelerometer via calibration with oxygen consumption (V˙⁡O(2)). DESIGN The study was a lab-based validation and calibration study. METHODS Forty-four children, aged 8-14 years, completed eight activities (ranging from lying supine to a medium paced run) whilst wearing GENEA accelerometers at th...

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
