About this study
Official title: 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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PLSOther
Participants will have to read standard textual information about the conducted systematic review (approximately 500 words)
BlogshotOther
Participants will have to read the blogshot information about the results of the Cochrane systematic review (approximately 100 words)
| Study group | Role | What they receive |
|---|---|---|
| PLS | Experimental | Plain abstract about the Cochrane systematic review. Receives: Other: PLS |
| Blogshot | Experimental | Blogshot presentation of the results of Cochrane systematic review. Receives: Other: Blogshot |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 3 months
Secondary outcomes (2)
Reading experience
Likert type scale 1-10 (1 indicating low preference for current presentation type, 10 indicating absolute preference for the current presentation type.
Measured: 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.
Measured: 3 months
