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 (MSCBC)
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.

The “Wall Question”
A single-item quality of life measure for aphasia
Overview
The Wall Question is a self-report rating on quality of life (QoL) for people with aphasia. This is a rating designed to gain insight into the perspective of the person with aphasia regarding the degree to which aphasia creates a barrier to participating in life. It is designed for use at a stage where the person with aphasia has some experience in living with aphasia – in other words, beyond the acute care phase of the healthcare continuum.
The speech-language pathologist asks the patient/client to rate their life with aphasia using a pictograph referred to as the “Wall Question”, excerpted from the Assessment for Living with Aphasia (ALA) (Kagan et al., 2011, 2013; Simmons-Mackie et al., 2014). The participant self-rates the impact of aphasia on their life using a 9-point rating scale ranging from 0 to 4 (with 0.5 intervals).

A recent study on the Wall Question that included 103 participants with aphasia provides evidence indicating that the measure is reliable and valid (Kim, Azios et al., 2025). A report on the study is currently in preparation.

(2) Introductory image for the rating scale;
(3) Pictographic support for the Wall Question.
Clinicians should be trained in the evidence-based method Supported Conversation for Adults with Aphasia (SCATM) (Kagan, Black et al., 2001). The free Introduction to SCATM eLearning module as well as in-depth SCATM training for healthcare professionals are available from the Aphasia Institute.
