About this study
The purpose of this study is to survey a sample of adults who have recently made a decision about treatment of high cholesterol or high blood pressure or a decision about screening for colorectal cancer, breast cancer, or prostate cancer. The main goal is to gather evidence of the validity and reliability of the Shared Decision Making Process scale. Secondary goal is to gather evidence on the quality of decisions for these common medical situations.
Read the detailed description
Study staff worked with a national sampling firm to recruit subjects for five different medical decisions. The five decisions are (1) treatment of high cholesterol, (2) treatment of high blood pressure (3) when to start breast cancer screening (4) whether or not to have prostate cancer screening and (5) which test to have for colorectal cancer screening. Respondents complete a survey about their experiences talking with health care providers about the specific clinical decision. The survey measured the amount of shared decision making, knowledge, preferences, decisional conflict and decision regret. The study will obtain 500 responses total, or 100 for each decision.
Sample is an online non-probability panel of adults living in the United States. In the survey, participants were screened to meet specific qualifications. After 1 week, a random selection of 50 respondents are invited to complete the retest instrument.
All analyses will be conducted separately for each group, and results may be pooled across cancer screening and medication contexts. First, study staff will examine the descriptives for the Shared Decision Making Process items. Study staff will also test several hypotheses to examine validity of the scores such as whether higher shared decision making process scores are associated with less decisional conflict and less regret. Staff will also examine retest reliability of the Shared Decision Making Process scale.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| High Cholesterol | People between the ages of 30-75 ,with no previous heart attack or stroke history, who have been diagnosed with high cholesterol, who are either taking medication for high cholesterol for 2 years or less; or have discussed managing high cholesterol in the past 2 years. These people will see items only pertaining to high cholesterol. | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Shared Decision Making Process Measure
The Shared Decision Making Process is a short patient-reported survey that measures the amount of shared decision making that occurs in an interaction. Scores range from 0-4 where higher values indicate a better shared decision making process occurred.
Measured: Baseline survey
Secondary outcomes (7)
Decisional Conflict Tool (SURE)
Measures decisional conflict, consists of 4 yes/no items. Scores range 0-4 where 0 indicates no decisional conflict, and scores 1 to 3 indicate decisional conflict. The measure is often reported as a top-score of 0, thus the percentage of patients with a total score of 0 or no decisional conflict.
Measured: Baseline survey
Decision Regret Scale
5-item decision regret scale ranges from 0-100 with higher scores indicating greater decisional regret.
Measured: Baseline survey
Single-Item Measure of Decision Regret
Single item asking "If you knew then what you know now, do you think you would make the same decision about [how to manage your high cholesterol/ how to manage your high blood pressure/breast cancer screening/colon cancer screening/ prostate cancer screening]?" where the last part varies by group.
Response options are:
Definitely yes, Probably yes, Probably no, Definitely no
Measured: Baseline survey
Treatment Choice
Single item asking patient "What did you want to do" in regard to (depending on the group) high cholesterol/high blood pressure/colon cancer screening/breast cancer screening/prostate cancer screening
Measured: Baseline survey
Adapted Controlled Preference Scale
Single item asking the participant who made the ultimate decision. The categorical response options are 1) the patient made the decision, 2)the provider made the decision, or 3) both patient and provider made the decision together.
Measured: Baseline survey
Shared Decision Making Process Measure Retest
The Shared Decision Making Process is a short patient-reported survey that measures the amount of shared decision making that occurs in an interaction. Scores range from 0-4 where higher values indicate a better shared decision making process occurred.
Measured: 1 week after baseline survey
Knowledge
Multiple choice knowledge items for each topic will be combined to a total knowledge score (0-100) with higher scores indicating higher knowledge
Measured: Baseline survey
