Evoluation of the Dutch and Turkish version
collecting observational data on the usability of the Turkish TTSQ. The data collected consisted of two types: 1. observations of participants’ behavior; and 2. think-aloud data. A video recording was made of this interview step. The video camera was aimed at the tablet computer and the hands of the participant while operating the screen. Additionally, both researchers MW and SB took real-time notes for use during the following steps of the interview, as well as for later analysis. The researchers wrote their notes down on hard copies of screenshots of the Dutch TTSQ, which were printed next to the identical screens of the Dutch questionnaire so researcher MW was able to read the question and answer options in Dutch. Researchers MW and SB noted problems with operating the tablet computer, including using the touch screen, navigating through the questionnaire, understanding the task given in each screen, selecting response items, using the correction function, and use of the stop and help buttons.
Step 2
Researcher MW interviewed each participant after they had finished completing the Turkish TTSQ. Data collection during this step was exclusively focused on filling possible gaps and checking the observational data collected during Step 1. An audio recording was made of this interview step.
Step 3
During Step 3 of the TSTI, researcher MW conducted a semi-structured interview aimed at eliciting experiences and opinions of participants. At the end of the interview, researcher SB asked complementary questions, if he felt it was necessary, in order to get complete and rich data. When participants encountered problems in operating the Turkish TTSQ, they were asked what they thought the exact nature and possible cause of each type of problem was. Additionally, they were asked how they tried to overcome the problem and if they had suggestions for making it easier to operate the Turkish TTSQ at this point. Then the participants were questioned about their satisfaction regarding the overall ease of use of the Turkish TTSQ. The participants were encouraged to report feelings, express opinions, state preferences and make recommendations. An audio recording was made of this interview step.
