ABSTRACT
Block modification courses are longer, require more therapist input and call for broader, probably less easily taught therapist skills. Thus, if the change produced by each approach were equivalent, block modification therapy could not be justified. Sufficient trust is particularly vital in block modification therapy where deeper personal issues tend to be explored. A major assumption in block modification therapy is that attitude and behavioural change must support each other. Though all block modification therapy is arguably desensitising, if change occurs merely in the context of being able to modify speech, the person is as likely to relapse as with fluency techniques. Intensive therapy is best understood as part of a comprehensive network of therapy. Clients tend to have therapy before and after our courses either with us or with the referring therapist.
