Informed Consent Formats by Information Preference and Priority

24. januar 2018 oppdatert av: Carnegie Mellon University
This study will test whether different formats of medical informed consent documents can help improve understanding and confidence in decision-making for clinical trials. The study will be primarily run through an online survey.

Detaljert beskrivelse

The goal of this study is to investigate whether the same information can be communicated in different formats of an informed consent document in ways that improve participant understanding and confidence. Participants will review one of several different versions of the same informed consent document, and will be asked to complete a survey after reading the documents. The survey will ask participants their willingness to enroll in the clinical trial discussed in the document and their confidence in their decision. The survey will also test participants recollection of information from the informed consent document. Researchers will look at this data to see if there are ways to improve knowledge about the clinical trial and confidence in decisions without necessarily changing enrollment preferences.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: Original
Participants will review the full-length, original consent form for the clinical trial.
Atferdsmessig: Original consent form
Participants will review the full-length, original consent form for the clinical trial.
Eksperimentell: Shortened
Participants will review a shortened consent form for the clinical trial, which includes only material indicated as important by 2/3 of participants from a previous study.
Atferdsmessig: Shortened consent form
Participants will review a shortened consent form for the clinical trial, which includes only material indicated as important by 2/3 of participants from a previous study.
Eksperimentell: Reordered
Participants will review a reordered, shortened consent form. This form is based on the shortened consent form, but the sections are reordered based on a previous study, such that sentences previously rated as more likely to impact a participant's decision is more likely to be presented first (except for an initial introductory section).

Eksperimentell: Highlighted
Participants will review a shortened consent form with a highlights box, where the highlights box includes the 10 sentences rates as most likely to impact a participant's decision from a previous study.

Participants will review a shortened consent form with a highlights box, where the highlights box includes the 10 sentences rates as most likely to impact a participant's decision from a previous study.
Eksperimentell: Interactive
Participants will review an interactive, shortened consent form, where hyperlinks to different sections of the consent form are provided. The landing page includes the introductory section.

Survey question of the following form:

'If you enrolled in the trial described in the consent form, what is the probability that the treatment could help control your asthma better, where 0% means "no chance at all of helping" and 100% means "would definitely help"?'

Participants provided with drop-down menu including values from 0% to 100% in increments of 1%.

Tidsramme
Participant's free-response text describing what was learned from reading the informed consent document
Tidsramme: through study completion, an average of 30 minutes

Survey question of the following form:

"What are some of the key things you learned from reading the informed consent document?"

Participants are then provided with an free-response text box where they are allowed to enter whatever text they want, as long as they enter some text. These responses will be coded by two independent coders, blinded to the treatment arms, using an emergent coding system to identify different topics that participants may raise.
