Level of Measurement

Dear All,

I was reading this article which I have to critically analyse and i'm confused about the level of measurement used for one of the outcome measures. Here is an extract of the article,

After the completion of each set of SEBT directional trials
under each condition, participants were questioned regarding
their perceived levels of stability, confidence, and reassurance
when performing the test compared with the practice
trials.22 Each participant was required to answer with 1
of the following options: (1) no change, (2) more than the
practice trial, or (3) less than the practice trial. Stability
referred to how steady and controlled the participant felt;
confidence referred to how well the participant believed
he/she could perform the test, and reassurance referred to
how confident the participant was that he/she would not
sprain their ankle while performing the test. For example,
after completion of the SEBT with either taping condition,
participants were asked “when performing the test, how
stable/confident/reassured did you feel compared to the
practice trials?” All questions were presented in written
format to the participant, who was asked to read the questions
and tick the appropriate answer.So participants were required
to select one of the three options which were, 'no change, more confident, less confident.'

So basically is the level of data generated nominal or ordinal.

Thanks,
