This study was designed to develop the Questionnaire Assessing School Physical Activity Environment (Q--SPACE) based on student perceptions. Twenty-eight items rated on 4-point Likert scales were administered to 244 middle school students in 9 schools. Exploratory factor analysis was used to evaluate the underlying structure of the items and 2 factors were extracted: physical environment (PE) and social environment (SE). Twelve and 8 items loaded saliently on PE (e.g., gym classes available) and SE (e.g., teacher encouragement), respectively. Factor scales had alpha coefficients of .86 (PE) and .81 (SE). One-week test–retest reliabilities for the factor scales of PE and SE were .78 and .72, respectively. Differences in PE scale scores across schools and PE and SE scale scores across student school physical activity behavior (e.g., participation on school teams) provided some evidence of scale construct validity. Overall, Q–SPACE demonstrates acceptable reliability for capturing middle school students' perceptions of school physical activity environment. The factorial validity needs to be assessed with confirmatory factor analysis and invariance testing procedures.  相似文献

Entry of men and women to an academic career was studied through a survey of 230 men and women who in 1991 held a full-time appointment at lecturer level or above in Arts and Science disciplines in an Australian university. The women more often than the men had learned about the position they obtained from a source inside the department in which the job was being filled, had been encouraged by senior members of the department to apply, and had gained a position that was filled without advertisement. However, these differences arose because more of the women than the men had been a tutor in the department where they gained a lectureship. There were no differences in terms of how men and women had been recruited when allowance was made for this factor and whether a person had been residing within Australia immediately prior to appointment. The results are discussed with reference to why men have in the past and now do substantially outnumber women among academics in Australian universities. Although the survey suggests men and women who gained positions were recruited on similar bases, successful applicants need to be compared with unsuccessful applicants to obtain comprehensive understanding whether selection practices have disadvantaged women.The survey reported in this article was undertaken while Ray Over held an appointment as Visiting Professor in the Faculty of Education at Griffith University.  相似文献
