Health Literacy Intervention for Informed Consent of Cancer Patients Considering Clinical Trial Participation
2015년 11월 2일 업데이트: Washington University School of Medicine
A Mixed Methods Study to Reduce Disparities in Cancer Clinical Trials by Adapting a Health Literacy Intervention for Informed Consent and Comparing it to Usual Care in a Randomized Experiment
This study will update an existing health literacy intervention (decision aid) for informed consent procedures and then conduct a randomized experiment implementing the health literacy intervention at Siteman Cancer Center and evaluate its effectiveness compared to usual care.
Our hypothesis is that implementing the targeted, web-based decision aid (DA) in addition to usual care will increase knowledge about cancer clinical trials.
Secondary outcomes include patients' ability to communicate with health care providers about trials, willingness to participate in trials, and enrollment rates for minority participants.
연구 개요
상세 설명
A previously developed and pilot tested web-based decision aid (DA) based on best practices in health literacy that is well received by minority participants and significantly improved knowledge about cancer clinical trials and decision self-efficacy will be used. This study will expand the reach of the DA and test it in a larger study in a different geographic region and center (Siteman Cancer Center). An additional benefit of conducting this work at Siteman Cancer Center is that Siteman and the Program for the Elimination of Cancer Disparities (PECaD) already institute structural changes at the system level to improve minority participation in trials. This study will activate and educate patients and will complement the system-level interventions.
By random 1:1 assignment, 180 participants will either receive:
*Targeted, web-based decision aid (DA) about participating in cancer clinical trials.
or
*Usual care/control-Access to the Siteman Cancer Center website about clinical trials.
Outcomes from the DA group will be compared to outcomes in a usual care/control group.

Knowledge About Cancer Clinical Trials
기간: 1 day (Immediately following either showing the participant the experimental or control information (same day)
|
A questionnaire will be administered to assess outcomes of interest immediately after showing the participant either the decision aid (DA) about clinical trials or the Siteman Cancer Center website about clinical trials.
The questionnaire will include eleven knowledge items such as "Only very sick patients are asked to take part in a cancer research study" and "Cancer research studies almost never involve the use of a placebo or sugar pill alone".
Participants will indicate each item as "True", "False", or "I don't know".
An overall knowledge composite score will be created with the average percentage of items participants in each condition correctly answer.
Participation in study concludes upon completion of questionnaire.

Clarity of Values
기간: 1 day (Immediately following either showing the participant the experimental or control information (same day)
|
A questionnaire will be administered to assess outcomes of interest immediately after showing the participant either the decision aid (DA) about clinical trials or the Siteman Cancer Center website about clinical trials.
The questionnaire will include the Values Clarity Subscale to evaluate decisional conflict.
The subscale includes two items from the ten-item Low Literacy Decisional Conflict Scale, each with three response categories.
The combined score on the two items will be divided by 2 and multiplied by 25 to produce an overall "values clarity" score from 0 to 100.
Higher values represent less clarity.
Participation in study concludes upon completion of questionnaire.

The combined score on the two items will be divided by 2 and multiplied by 25 to produce an overall "uncertainty" score from 0 to 100.
Higher values represent more uncertainty.

Self-efficacy for Communicating About Cancer Clinical Trials
기간: 1 day (Immediately following either showing the participant the experimental or control information (same day)
|
A questionnaire will be administered to assess outcomes of interest immediately after showing the participant either the decision aid (DA) about clinical trials or the Siteman Cancer Center website about clinical trials.
The questionnaire will include an item in which participants rank their self-efficacy for finding information about cancer clinical trials on a 5-point scale with higher numbers indicating greater self-efficacy.
Participation in study concludes upon completion of questionnaire.

A questionnaire will be administered to assess outcomes of interest immediately after showing the participant either the decision aid (DA) about clinical trials or the Siteman Cancer Center website about clinical trials.
The questionnaire will include two items in which participants rank their intent to participate in a cancer clinical trial and their intent to encourage others to participate in a cancer clinical trial on a 5-point scale with higher numbers indicating greater intent.
