Key: Cronbachs α for applicable scales are reported in parenthesis along the diagonal. A total of 175 employees completed the questionnaires. Gender (1 = male, 2 = female); Marital status (1 = single, 2 = married); Job position (1 = junior staff, 2 = senior); Education (1 = below degree certificate, 2 = degree certificate and above). Raw scores of other variables were entered as they were collected.

* p < .05.

** p < .01.

*** p < .001.
