The researchers wrote their notes down on hardcopies of print screens of the DTTSQ.
Step 2: after the respondent finished completing the DTTSQ, researcher IT conducted an in-depth interview to clarify and complete the observational data. During this step, researcher IT only focused on those actions or thoughts she felt not fully informed about or were not fully clear to her.
