Less effective for some types of phobias:
Flooding works well for specific phobias e.g. snakes, feet, spiders etc
It works well for social phobias. This is because social phobias have a less behavioural response, and more of a cognitive response, e.g. traumatic thoughts about social situations.
Suggests that these types of phobias may benefit more from cognitive therapies, rather than behavioural ones.
