The table describes the three options of the OSS-3, i.e. the question, the response categories, and the corresponding scores.
It is recommended to use the OSS-3 for each separate item as well as for the total score. The total score is calculated by adding up the raw scores for each item. The sum of the raw scores has a range from 3-14. A score ranging between 3 and 8 is classified as poor support, a score between 9 and 11 as intermediate support, and a score between 12 and 14 as strong support.
| The Cronbach’s alpha is relatively low (.60). This figure reflects the correlation between the items of a scale, and is often used as an indicator for the reliability of a scale. In this case, however, the low Cronbachs’s alpha does not necessarily reflect a low reliability, but rather the multidimensional structure of the index.
