+ Wolpe
Wolpe found that when he continued to drive around a girl who was afraid of cars, she moved from being hysterical to being calm - suggests research evidence backs up flooding as an effective phobia treatment, validating the treatment
+ Very quick
The treatment can be a very quick way of eradicating a fear - suggests that patients are more likely to comply with the treatment as it does not take long, validating the treatment
Success rates for flooding tend to be lower in general than those for other types of therapy - suggests flooding does not work in 100% of cases, and therefore likely should not be recommended over other more effective methods, reducing its validity as a treatment
There are issues surrounding the ethics of the treatment - suggests the treatment can cause severe distress in many patients and therefore likely should not be recommended to them
