Trial Outcomes & Findings for Presenting Summary Information From Cochrane Systematic Reviews: Protocol for Research of Infographics Presentation vs. Plain Language Summary (NCT NCT02980107)

NCT ID: NCT02980107

Last Updated: 2019-06-03

Results Overview

The questions will focus on understanding the benefits and risks of the intervention and the quality of evidence described in the systematic review. There will be 10 open ended questions, which will be assessed by two assessors, and the total score will be the sum of correct answers (total score ranging from 0-10). Higher scores would represent greater understanding of the content.

SECONDARY outcome

Timeframe: One month (30 days)

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 5, maximum 50). Greater scores indicate more positive reading experience.

SECONDARY outcome

Timeframe: One month (30 days)

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 5, maximum 50). Higher scores indicate greater perception of the summary format as more user friendly.

OTHER_PRE_SPECIFIED outcome

Timeframe: One month (30 days)

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.
