Considered more ethical than other behavioural therapies such as 'floodingtechniques'
In SD each step is conducted slowly + at a pacedictated by the client - so the therapist can gauge whether the client is fullyrelaxed at each stage
The therapist must only attempt to moveup the hierarchy when the client is comfortable - anxiety should not be an issue
Ethical issues - Able to provide valid consent
SD is mainly used with phobias + not otherproblems such as depression + schizophrenia - the client is 'healthy' enough to be in the rightframe of mind to understand the therapy - validconsent
The client also attendstherapy at their own freewill + can withdraw at any point
