The consistency of scores over time suggests that the questionnaire is reliable, as it yields stable and consistent results across different administrations. Reliability refers to the consistency of a measure, and in this case, administering the questionnaire at two different times and getting consistent scores indicates that the questionnaire reliably measures what it is supposed to measure.
