Revised Rating Anchors and Scoring Procedures for Measure of Skill in Conversation (MSC) and Measure of Participation in Conversation (MPC) Between Adults with Aphasia and their Conversation Partners
The Measure of Skill in Supported Conversation (MSC) and Measure of Participation in Conversation (MPC) are two complementary measures designed to capture elements of conversation between adults with aphasia and their speaking conversation partners.
The MSC provides an index of the conversation partner’s skill in providing conversational support. The MPC provides an index of the level of participation in conversation by the person with aphasia.
The rating anchors for both measures have been revised to be more generically applicable (Kagan, Simmons-Mackie, & Shumway, 2018).
Note: Anchors should change according to situation.
For background to the original development of the MSC/MPC, including preliminary psychometric evaluation, please refer to the following article:

Aphasia Severity Rating (ASR)
The ASR is a single observational rating that was designed to provide an index of the severity of the aphasia language impairment.
