Trial Outcomes & Findings for Presenting Summary Information From Cochrane Systematic Reviews (NCT NCT02918656)

Last Updated: 2019-06-04

Results Overview

The primary outcome of the study is the score on a understanding test with ten questions about information contained in all three forms of presentation, titled as "Understanding information about external cephalic version for breech presentation before term" (Hutton et al, 2015). The questions will focus on understanding the benefits and risks of the intervention and the quality of evidence described in the systematic review. Each correctly answered question will be awarded one point, with a maximum of 10 points. The scale was specifically designed for this research, they ask about the information contained in all three abstract format and all questions are open-ended.

SECONDARY outcome

Timeframe: One hour after the intervention

This section of the survey will include 5 questions about the experience of participants about the text they read, measured on a 10-point Likert type scale, where 1 means do not agree at all and 10 means fully agree. The total score is the sum of scores on all five answers (minimum score was 10 and maximum 50). Higher scores indicate greater reading experience, which means that a person was assessed that type of reading material as more enjoyable. So, higher scores are associated with more positive reading experience.

SECONDARY outcome

Timeframe: One hour after the intervention

This section of the survey will have 5 questions concerning how easy it was for the participant to find relevant information, measured by a 10-point Likert type scale where the answer 1 means I do not agree at all and 10 means I fully agree. The total score is the sum of scores on all the answers (minimum score was 5, maximum 50). The higher score indicated that the reading material was perceived as more user friendly and that it was easier to find the desired information.

SECONDARY outcome

Timeframe: One hour after the intervention

This section will use 6-item General health numeracy test (Osborne et al., 2013) in order to determine how much our participants understand the basic health instructions regarding numeracy dimension. For each correct answer, the participants receive one point and the total score is the sum of all correct answers.
