Comparison of Blogshot Formats With Standard Cochrane Plain Language Formats

Comparison of Blogshot Formats With Standard Cochrane Plain Language Formats: Randomized Controlled Trial

Participants will receive in random order on format of brief description of systematic review summary on health intervention. One group will receive standard plain language summary, while another will receive Cochrane blog shot, containing only few information about the efficacy of the intervention. After reading, their task will be to answer several questions about the material they have read.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Understanding	Number of the correct answers about the content of the summary, which will consist of four multiple choice questions (with four possible answers where only one is correct, for each question) about the text the participants are reading. Questions will be developed by research team and revised by expert in health communication. The scale ranges from 0-4, where greater score indicates better understanding of the material.	3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Reading experience	Likert type scale 1-10 (1 indicating low preference for current presentation type, 10 indicating absolute preference for the current presentation type.	3 months
Health numeracy	5 questions about the numerical tasks placed in medical content, total score is number of correct answers on those questions. The five questions are part of Numeracy Understanding in Medicine Instrument (Schapira et al, 2012), and we will translate only the questions focusing on Probability section. Cronbach's alpha in previous research was 0.86 (Schapira et al, 2012). The questions will be revised by independent translator and back translated to English.	3 months
