Operationalized definitions of ratings with examples.

Rating	Definition	Example	Rationale
Rating = 2: Successful transaction	Response reflects comprehension of prompt and conveys to the communication partner meaningful information related to immediate prompt	P: What are you doing this weekend? PwA: We in NFL Saturday and Sunday	Conveys meaningful information despite syntactical error
Considerations:  ◆ Graphemic/spelling errors acceptable as long as word is recognizable;  ◆ Morphological and syntactical errors that do not affect meaning are acceptable;  ◆ Successful self-corrections are acceptable  ◆ Irrelevant or additional words or graphemes that do not change meaning are acceptable.		P: What about dinner? What kind of food should we have? PwA: pizza like	Conveys meaningful information; additional word does not alter meaning
Rating = 1: Partial transaction	Response provides partial or incomplete information that conveys to the communication partner meaning within the context of the prompt	CP: What about dinner? What kind of food should we have? PwA: Subway for dinner. Mexico!	Communication partner needs to clarify due to incongruent information (Do you want Subway or Mexican food?)
Considerations:  ◆ Response may reflect impaired comprehension of prompt, e.g.,   ○ answers a related question, such as a similar “wh” question   ○ conveys temporally inaccurate information   ○ conveys a request for clarification.  ◆ Response to which communication partner may need to clarify, i.e., communication burden shared with communication partner,   ○ response contains words or additional information that may alter the meaning or information that is incongruent.		P: When should we go? PwA: Nick's	Response reflects impaired comprehension; answers “where” with name of restaurant
		P: What are you doing this weekend? PwA: I saw a good movie.	Response reflects impaired comprehension of prompt; temporally inaccurate
Rating = 0: No successful transaction	Response does not convey to the communication partner meaningful information within the context of the prompt	P: When should we go? PwA: I go…	Not meaningful relative to the prompt; word from prompt is repeated without additional information
Considerations:  ◆ Response contains words or graphemes that are unrecognizable in the context  ◆ Response repeats prompt or part of prompt without adding additional meaningful information		P: What are you doing this weekend? PwA: i w e	Single graphemes that do not convey meaningful information

Note. P = prompt; PwA = person with aphasia.
