(1) Four-factor model: decision-making autonomy, work scheduling autonomy, work method autonomy, job satisfaction; (2) Two-factor model: based on the four-factor model; combines decision-making autonomy, work scheduling autonomy, and work method autonomy into one factor; (3) Single-factor model: based on the four-factor model; combines the four construct variables into one factor; (4) RMSEA is the abbreviation of root mean square error of approximation; (5) SRMR is the abbreviation of standardised root mean square residual; (6) CFI is the abbreviation of comparative fit index; (7) TLI is the abbreviation of Tucker–Lewis index; (8) GFI is the abbreviation of goodness of fit index
