All six items of question 9 were answered by the 240 respondents, using the full range of the response scale for all items. However, with the exception of item a and item f, the frequency distributions of the items are left or right skewed, that is, the (sometimes large) majority of respondents agreed or disagreed with the respective statements. To determine the internal consistency of the 6-item scale, Cronbach's alpha was calculated. This internal consistency was acceptable (cf. George & Mallery, 2002, p. 231), with Cronbach's alpha = 0.70.
The aim of the pretest was to investigate whether the individual statements were comprehensible to the test persons. The corresponding cognitive probes (N1_F9 and N2_F9, see Appendix) were asked of the 124 subjects who were (randomly) assigned to Group 1.
Only one of the 124 respondents indicated that one item (item e) was unclearly worded. However, the response when asked what was unclear about it did not indicate that the respondent had trouble answering it, but rather that she wanted to explain her answer to this item in more detail: "I want there to be simply one toilet for all genders. Cubicle closed and done!" (TP248, response: strongly disagree).
