A weakness of research on gender differences in coping with stress is that
there may be confounding variables that may be important in explaining the
The degree of social support that men and women receive may act as a
confounding factor. Women are more likely to receive social support than
men and social support reduces the amount of stress experienced.
This matters because women may be experiencing less stress and as a
consequence select different coping styles rather than vice-versa.
Therefore, this will reduce the internal validity of research.
