The implementation of PCIT in the home has been examined in order to increase accessibility. Protocol was followed as closely as possible, with the exception that treatment was conducted within the home. Some modifications may be necessary in this setting. For example, the bug-in-ear (a small, wireless earpiece) was used for coaching parents could not be used. Instead, therapists were present in the same room for coaching, typically behind the caregiver, giving discrete feedback. Therapists were able to conduct DPICS observations, however these observations were coded live.
