RESULTS
Effectiveness
Nine out of the twenty-four participants in this study did not complete the DTTSQ fully (see table 4.2.3). Michelle (56yrs), Bill (72yrs) and Helga (54yrs), who were all inexperienced in using mobile technology stopped completing the questionnaire by using the stop button. Inexperienced Ida (66yrs), Ilene (79yrs), Dora (77yrs) and Mia (73yrs) and little experienced Peter (18yrs) and Rose (60yrs) went through the whole questionnaire but unintentionally left one or more parts open.

Unanswered (parts of) questions
Inexperienced Michelle (56yrs), Ida (66yrs), Ilene (79yrs), Dora (77yrs), Mia (73yrs) and little experienced Peter (18yrs) and Rose (60yrs) failed to fully complete the DTTSQ because they failed to select answer options and/or unintentionally skipped questions by double-tapping on the next button (see problem 1-5 in table 4.2.4). All participants, except for Michelle, additionally failed to notice they had not effectively selected an answer because the difference between activated and non-activated answers was not accentuated enough (see problem 6 in table 4.2.4).
