Although ETRP has been shown to be an efficacious therapy for OCD, problems have been noted with a minority of clients refusing or dropping out of treatment.
In an attempt to remedy this situation, a readiness intervention (RI) has been designed (Maltby & Tolin, 2005; Tolin & Maltby, 2008) to target the clients who initially refuse ETRP therapy.
Other components of the RI included education about OCD and its treatment, the construction of a sample exposure hierarchy that would be used if the client were to enter ETRP in the future, viewing a videotape of ETRP, and having a private telephone conversation with a client who had completed ETRP.
If people close to the client are not educated about OCD, overly accommodating or overly antagonistic attitudes can interfere with treatment and result in a poorer outcome for ETRP. Moreover, family members who have received proper psychoeducation in OCD can be helpful to the client in carrying out homework assignments.
has been subjected to numerous efficacy trials in routine clinical practice, some involving small groups of clients (see, for example, Kirk, 1983; Krone, Himle, & Nesse, 1991), and others using individual clients whose outcomes were evaluated using single-case research designs (Himle & Thyer, 1989; Thyer, 1985).
