MSC/MPC

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

Overview

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.

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.

Measure of Supported Conversation & Behavior Change

The Measure of Supported Conversation & Behavior Change (MSCBC) rating scale is an adaptation of the Measure of Skill in Supported Conversation (MSC) (Kagan et al. 2018). The MSCBC is designed to assess aphasia therapy sessions by rating a speech-language pathologist’s (SLP) skill in providing communication support/managing the therapy interaction and also using behaviors known to promote behavior change. A small pilot trial found the tool to be reliable, but further psychometric testing is needed to confirm that the MSCBC reliably captures SLP skill in interaction and support of behavior change.
