Sample B employed a
stratified random sampling method. The application of stratified random sampling
ensures that each subgroup of the population is adequately represented in the
sample, thereby providing a more comprehensive overall coverage.Firstly, we divided China into four primary sampling
units: Eastern, Central, Western, and Northeastern regions, based on the
division of economic regions by the National Bureau of Statistics of China.
Then, within each unit, two teacher education colleges or comprehensive
universities were selected as secondary sampling units. Finally, according to
the principle of random sampling, we distributed and collected at least 50
questionnaires in each selected institution, resulting in a total of 543 collected
questionnaires. CFA
of Sample B was conducted using the maximum likelihood method in AMOS 26.0
software, preceded by a test of normality. Convergent validity and discriminant
validity were analyzed, focusing on correlations among measurement items within
factors and between factors, respectively. Reliability testing employed
Cronbach's alpha coefficient. These methods systematically examined the
validity and reliability of the scale.
