13. Assume there is a significant correlation between coping strategies and quality of life (+ .76, p < .001). Assume self-efficacy is then partialled out, and the correlation reduces to .21 (p = .70). Which is the most sensible conclusion?

a) The relationship between coping strategies and quality of life is spurious

b) Self-efficacy shows no relationship between coping strategies and quality of life

c) A small part of the relationship between coping strategies and quality of life can be explained by the relationship between selfefficacy and the other variables

d) A large part of the relationship between coping strategies and quality of life can be explained by the relationship between selfefficacy and the other variables
