Identifying “task markers”, a concept which can be referred in psychotherapy process research literature as client "problem state”, too (Greenberg & Dompierre, 1981), is the first step of Greenberg’s task analysis method. In order to explore and identify every relevant task of a specific psychotherapy process, it would be needed to establish a previous consensus about what is and what is not a task marker.
I have no suggestions but this seems to be a very interesting topic and I would like to follow you to keep up with your findings.
I am not sure this will fully answer your question, but the technique think-aloud protocol could be interesting to compare user behavior with task completion.
The technique has qualitative caracteristics and can help identify usability, affordance and function recognition problems with few (very well selected as representatives of final user) participants. open interview after the technique procedure can help identify specifics and explore more deeply some of the identified problems in the course of interaction. If you are interested in reading more about it, I have a few papers regarding the technique in portuguese, but only one in english:

Villanueva also has an extensive work regarding the technique
Hope this has helped.

Thank you, Adriano, for your answer.
I didn't know about think-aloud protocol. I've just taken a look to this research method, and it seems to me like it could be a valuable one in psychotherapy process research. It seems to be a usefull method in order to know how tasks are solved. My question is, however, about how to decide what is and what is not a psychotherapeutic task (in the context of "task analysis" method). Should psychotherapeutic task be defined as specific techniques completion (notwithstanding the reason why this technique was initiated), as in-session client's "negative emotions" or "problem states" resolution, as a challenge perceived by the therapist...? In "task analysis" literature (see the link below to find a review), analyzed task sometimes simultaneously meet all of this criteria, nevertheless, sometimes they do not. So... it seems like there is not a consensus about what is and what is not a psychotherapeutic task.
Anyway, I need to read more about think-aloud protocol, of course, to know it better. So I appreciate you facilitate me your articles about this method.
