limb while in a single-limb stance on a centralized platform. It was developed from the star excursion balance test (SEBT) in an attempt to address common sources of error and method variation noted in the SEBT ( Plisky, Gorman, Butler, Underwood, & Elkins, 2009 ). The SEBT has been shown to be a valid

Therefore, the main purpose of this study was to evaluate the validity between PO for measuring the AOP

The current study presents the development process and initial validation of a measure designed for assessing psychological needs thwarting (frustration) in a secondary school physical education context (Psychological Needs Thwarting Scale in Physical Education, PNTSPE). Secondary school students (grades 7–9) from Hong Kong (N = 1258) were invited to participate in three studies. In Study 1, item generation and initial content validity of the PNTSPE were achieved. In Study 2, the factorial structure of the measure was tested using exploratory and confirmatory factor analysis. Internal consistency reliabilities of the subscales were also examined. In Study 3, the reliability and validity of the scores derived from the PNTSPE were further examined in an independent sample. Overall, the findings from the three studies provided initial psychometric evidence for the PNTSPE and suggested that the PNTSPE could be used as a valid and reliable measure to assess Hong Kong secondary school students’ psychological needs thwarting in physical education.

The objective was to determine the test-retest reliability and criterion validity of the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD).


Forty-five non-wheelchair dependent subjects were recruited from three Dutch rehabilitation centers. Subjects’ diagnoses were: stroke, spinal cord injury, whiplash, and neurological-, orthopedic- or back disorders. The PASIPD is a 7-d recall physical activity questionnaire that was completed twice, 1 wk apart. During this week, physical activity was also measured with an Actigraph accelerometer.


The test-retest reliability Spearman correlation of the PASIPD was 0.77. The criterion validity Spearman correlation was 0.30 when compared to the accelerometer.


The PASIPD had test-retest reliability and criterion validity that is comparable to well established self-report physical activity questionnaires from the general population.
