This evaluation has accepted the basic foundation and concepts of the Multiple-Item Waiting Scale and later transformed into a medical focused survey. A direct measurement approach has been adopted to evaluate factors related to consumers' personality characteristics, customers' waiting circumstances, and unique background factors which have impacts on waiting quality. The result showed this particular Scale to be effective due to its good reliability, validity measurements, and clear explanations. This evaluation also proved how personality traits, self versus group waiting, environment familiarity, time pressure, doctor appointment timings, age, and occupations have affected the overall waiting quality evaluations.
