It is imperative to have an appropriate PCIT room set-up to implement PCIT in your clinic. The basic set-up for PCIT rooms will include a one-way mirror, side-by-side rooms (therapy room, observation room, and barrier room), an adult-sized table with two chairs to accommodate a caregiver and child, an adult-sized sturdy time-out chair, and at least three choices of CDI-appropriate toys. Average-sized treatment rooms are preferred rather than larger conference rooms. A sound system (microphone and amplifier) is necessary to hear the interaction between caregiver and child while you stand on the other side of the one-way mirror in the observation room, and a "hearing helper" system will be necessary for speaking to the caregiver through a microphone and headset device. A timer is important when coding the caregiver's skill level each week. Videotaping sessions also allows for session review by consultant or supervisor, your review of caregiver skill level, and as a reference as the sessions progress. A barrier room (or "time-out" room) is preferred but not required. A barrier room is ideally approximately 4X6 feet or so - no smaller than 4X4 and no larger than a small office - and it must have adequate light and ventilation. When designing a barrier room, consider having a "dutch door" cut off approximately 5 feet high and/or a safety glass window into the time-out room to permit visual contact.
