The current study presents the development process and initial validation of a measure designed for assessing psychological needs satisfaction in a secondary school physical education context (Psychological Needs Satisfaction Scale in Physical Education, PNSSPE). Junior secondary school (grades 7 to 9) students (N = 1,258) were invited to participate in three studies. In Study 1, item generation (34 items) and initial content validity of the PNSSPE were achieved. In Study 2, the factorial structure of the PNSSPE was tested using exploratory and confirmatory factor analyses. Internal consistency reliabilities of the subscales were also examined. In Study 3, the reliability and validity of the scores derived from the PNSSPE were further examined in an independent sample. Overall, the PNSSPE demonstrated good content, factorial, discriminant, and nomological validities. It also demonstrated acceptable internal consistency and test-retest reliability. The measurement model was proven invariant across gender and samples. Psychometric evidence from a series of studies suggests that the PNSSPE could be used as a reliable and valid measure to assess Hong Kong secondary school students' satisfaction of psychological needs in physical education.

The main purpose of this study was to develop a Rasch Measurement Physical Fitness Scale (RMPFS) based on physical fitness indicators routinely used in Hong Kong primary schools. A total of 9,439 records of students' performances on physical fitness indicators, retrieved from the database of a Hong Kong primary school, were used to develop the Rasch scale. Following a series of iterative Rasch analyses that adopted the 'data should fit the model' approach, four physical fitness indicators (such as 6-min run, 9-min run, 1-min sit-ups, and dominant handgrip) were successfully calibrated to form the RMPFS. The RMPFS and its scale indicators showed fit to the Rasch model sufficient for the intended purposes of measuring the overall fitness of children. The overall physical fitness measure reflects children's fitness on three key core components of physical fitness - cardio-respiratory fitness, muscular endurance, and muscular strength. Advantages of the RMPFS are discussed, and recommendations for future research follow. The findings of this study provide a better knowledge basis for interpreting children's physical fitness assessment results.

The purpose of this study was to examine the underlying structure of the second edition of the Test of Gross Motor Development-2 (Ulrich, 2000) as applied to Chinese children. The Test of Gross Motor Development-2 was administered to 626 Hong Kong Chinese children. The outlier test with standard scoring was utilized. After data screening, a total of 614 cases (N = 614) were used for further analysis. The two-factor structure of the Test of Gross Motor Development-2 was tested using confirmatory factor analysis with maximum likelihood estimation to compute parameter estimates and to select the appropriate item for each factor. The goodness-of-fit indices supported that the model was tenable (goodness-of-fit index = .95, root mean square error of approximation = .06, standardized root mean square residual = .04, comparative-fit index = .97). The findings of this study suggested that the two-factor structure proposed by Ulrich (2000) fit the data of Hong Kong Chinese children.
