The purpose of this retrospective observational study is to evaluate the performance of the Shared Decision Making Process scale in a sample of patients who have received a decision aid about the decision to screen or not screen for breast cancer, colon cancer, prostate cancer, or lung cancer.
This is a retrospective observational study that will examine the performance of the Shared Decision Making Process in a sample of patients who made a decision about cancer screening in the last 2 years. Patients from 4 hospitals who have received a patient decision aid for breast, colon, prostate, or lung cancer screening will be screened for eligibility. A random sample of eligible patients will be sent a one-time survey. The survey asks patients about their experiences talking with healthcare providers about the specific cancer screening decision. The survey includes the Shared Decision Making Process scale, knowledge, preferences, decisional conflict and decision regret. The study will obtain 400 completed surveys, or 100 for each cancer topic. The sample consists of patients who received a decision aid for cancer screening within the last two years and meet specific qualifications. All analyses will be conducted separately for each group, and results may be pooled. First, study staff examine the descriptives for the Shared Decision Making Process items. Study staff will also test several hypotheses to examine performance of the scores such as whether higher shared decision making process scores are associated with less decisional conflict and less regret.

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 outcome.
Time frame: Baseline survey
The 9-item Shared Decision Making Questionnaire
The Shared Decision Making Questionnaire measure measures the amount of shared decision making that occurs in an interaction. Scores range from 0-100 where higher values indicate a better shared decision making process occurred.
Time frame: Baseline survey
Decisional Conflict Tool (SURE)
Measures decisional conflict, consists of 4 yes/no items. Scores range 0-4 where 0 indicates extremely high decisional conflict, 4 indicates no decisional conflict. The number who get score of 4 is reported indicating no decisional conflict.
Time frame: 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 \[breast cancer screening/colon cancer screening/ prostate cancer screening/lung cancer screening\]?" where the last part varies by group. Response options are: Definitely yes, Probably yes, Probably No, Definitely No
Time frame: Baseline survey
Treatment Choice
Single item asking patient "What did you want to do" in regard to (depending on the group) colon cancer screening/ breast cancer screening/ prostate cancer screening/ lung cancer screening.
Time frame: Baseline survey
Adapted Controlled Preference Scale

Single item asking the participants who made the ultimate decision. The categorical response options are: 1. the patient made the decision 2. the provider made the decision 3. both patient and provider made the decision together.
Time frame: Baseline survey
Knowledge
Multiple choice knowledge items specific for each topic will be combined to a total knowledge score (0-100) with higher scores indicating higher knowledge. These items are part of the knowledge subscale in the published Decision Quality Instruments.
Time frame: Baseline survey
