THERapy-Related InterACTion (THER-I-ACT) in Rehabilitation-Instrument Development and Inter-Rater Reliability.

To develop an instrument for the observation of therapeutic communication interactions during rehabilitation sessions and test its inter-rater reliability. The new instrument THER-I-ACT (THERapy-related Inter-ACTion) has been designed to assess both the frequency and timing of therapeutic interactions in the thematic fields information provision, feedback, other motivational interaction, and bonding. For this inter-rater reliability study, a sample of stroke survivors received arm rehabilitation as either arm ability training, arm basis training, or mirror therapy, or neglect training as individually indicated.
