Evidence - Gilroy (2002) followed up on 42 PPTs in an SD spider phobia, at 3 and 33 months, SD group were less fearful than the control group (treated with relaxation, not exposure)
Economical impacts - More accepted by PPTs as it has lower refusal rates, wasting less time and effort
Cons:
Flooding:
Pros:
Time/cost effective - Flooding is shown to be completed within one session saving time and money for both the patient and therapist
Cons:
Ethical implications - Can cause high anxiety/ stress to patient potentially causing long-term psychological harm
less effective - for complex phobias with anxiety/cognitive aspects therefore cognitive therapy may be more effective
