Primary | Decisional conflict | measured with on the decisional conflict scale. Measured by the decisional conflict scale ( O'Connor, 1995), This contains 16 questions answered on a 5 point likert scale( strongly agree-strongly disagree). Items are given a score value of 0-4. The total score is calculated by: summed, divided by 16 and multiplied by 25. scores range from 0 ( no decisional conflict to 100 (extreme high decisional conflict). The scale also consist of 5 subscales: uncertainty subscore, informed subscore, values subscore, support subscore and the effective decision subscore. |
90 days after the decision on their radiation treatment has been made | |
Secondary | Improvement on the perceived level of shared decision making. | measured with the 9-item Shared Decision Making questionnaire (SDM-Q-9,( Kriston 2009)). This contains 9 questions answered on a 6 point likert scale, ranging from 0 ( completely disagree) to 5 ( completely agree). The total score is calculated by: summed score multiplied by 2.2222 transforming to a scale from 0 to 100. | 90 days after the decision on their radiation treatment has been made | |
Secondary | Improvement on the perceived level of shared decision making. | measured with the collaboRATE questionnaire ( Barr 2014), This contains 3 questions answered on a 10 point anchored scale, ranging from 0 ( no effort was made) to 9 ( every effort was made). The total score is calculated by: summed score multiplied by 3.704 transforming to a scale from 0 ( no effort made) to 100 (every effort made). | 90 days after the decision on their radiation treatment has been made | |
Secondary | Patient knowledge | measured with a ( self developed) knowledge test. This contains 11 questions with 3 possible answers ( True, not true and don't know). For every right answered question 1 point, wrong answers -1 and don't know 0 are given resulting in a range from -11 ( all answers wrong) to 11 ( all answers right). | directly after the decision on adjuvant RT has been made (<3 days) | |
Secondary | Decisional conflict | measured with on the decisional conflict scale Measured by the decisional conflict scale ( O'Connor, 1995), This contains 16 questions answered on a 5 point likert scale( strongly agree-strongly disagree). Items are given a score value of 0-4. The total score is calculated by: summed, divided by 16 and multiplied by 25. scores range from 0 ( no decisional conflict to 100 (extreme high decisional conflict). The scale also consist of 5 subscales: uncertainty subscore, informed subscore, values subscore, support subscore and the effective decision subscore. |
365 days after the decision on adjuvant RT has been made | |
Secondary | Prospective process evaluation | how many patients did effectively use the decision aid and how many consultations were needed for the decision to be made. Measured by a log system on the decision aid and by consulting the patients on how many consultations they hade before making the decision. | directly after the decision on adjuvant RT has been made (<3 days) |
