Question relate to a study by van der Colff and Rothmann (2009) who assessed whether or not occupational stress, sense of coherence and coping strategies predict burnout and the work engagement of registered nurses. The table below shows a multiple regression analysis with emotional exhaustion as the criterion variable and three types of stress as the explanatory (predictor variables).

15. Which of the following is true?

a) The three predictor variables together account for 14% of the variation in scores on emotional exhaustion

b) The lack of organisational support does not predict emotional exhaustion

c) Nursing-specific demands are very important in the prediction

d) As the stress of job demands increase by one standard deviation (SD), emotional exhaustion increases by .27 of a
