A two-arm, randomized study will be conducted in patients about to undergo consent discussion for participation in two large, multicenter BMT CTN clinical trials. Once they agree to participate in this Easy-to-Read Informed Consent (ETRIC) study, they will go through the consent process for the parent trial using either a standard or the ETRIC consent form. The content of both forms will be similar but the ETRIC form will incorporate a two-column format with specific attention towards enhanced readability and processability. Following the consent discussion for the BMT CTN parent trial, patients will complete assessments of health literacy, comprehension of the parent trial and satisfaction and anxiety related to the consent process. These assessments will be completed within 7 business days of the consent discussion of the parent trial.
Notes: Enrollment on the BMT CTN 0901 trial (NCT01339910) was closed to further accrual on April 18, 2014. Enrollment on the BMT CTN 1203 trial (NCT02208037) completed accrual on May 13, 2016.

Active Comparator: Standard Consent
This arm will receive the Consent Form Specific Format 1 'standard consent'. The standard consents are already approved and used for the BMT CTN 0901, 1101, 1203, and 1301 trials.
Other: Consent Form Specific Format 1
The Consent Form Specific Format 1 is the 'Standard Consent'. The standard consent does not have the format of two-columns with changes in layout readability, organization of content, typography and use of plain language. Standard consents are already used by sites for the BMT CTN 0901, 1101, 1203, and 1301 clinical trials.
Experimental: Easy-to-Read Informed Consent
This arm will receive the Consent Form Specific Format 2 'Easy-to-Read Informed Consent'.The Easy-to-Read Informed Consent (ETRIC) is the newly approved consent.
Other: Consent Form Specific Format 2
The Consent Form Specific Format 2 is the 'Easy-to-Read Informed Consent'.The Easy-to-Read Informed Consent is two-columns with changes in layout readability, organization of content, typography and use of plain language.
- Quality of Informed Consent Part A (QuIC-A) Score [ Time Frame: Within 7 days of consent discussion ]The primary objective of the trial is to compare objective comprehension scores on the Quality of Informed Consent (part A) instrument between subjects randomized to the ETRIC versus the standard consent arms. The QuIC-A is scored on a normalized scale from 0 to 100, with a higher score indicating a greater level of comprehension.
- Quality of Informed Consent Part B (QuIC-B) Score [ Time Frame: Within 7 days of consent discussion ]The Quality of Informed Consent Part B measures participants' perception of their understanding of cancer clinical trials to address 13 independent domains of informed consent. The QuIC-B is scored on a normalized scale from 0 to 100, with a higher score indicating a greater level of perceived understanding.
- Modified Deaconess Informed Consent Comprehension Test (DICCT) [ Time Frame: WIthin 7 days of consent discussion ]The Modified Deaconess Informed Consent Comprehension Test (DICCT) uses semi-structured interviews to assess subject's understanding of the study for which they participated in an informed consent discussion. This modification of the DICCT has 11 items, each scored from 0 to 2 (0 = incorrect, 1 = partially correct, 2 = correct). The item scores are summed to produce a total score ranging from 0 to 22. A higher score indicates a higher level of comprehension.
- REALM-R Score [ Time Frame: Within 7 days of consent discussion ]The Rapid Estimate of Adult Literacy in Medicine-Revised (REALM-R) is an 8-item word recognition test to provide clinicians with a valid quick assessment of patient health literacy. The score is computed as the number of words out of 8 that the patient pronounces correctly.
- Newest Vital Sign (NVS) Score [ Time Frame: Within 7 days of consent discussion ]The Newest Vital Sign is a screening tool that identifies patients at risk for low health literacy. It consists of a nutritional label accompanied by five questions about information on the label. The score is equal to the number of questions answered correctly.
- State Trait Anxiety Inventory (STAI) Score [ Time Frame: Within 7 days of consent discussion ]The State Trait Anxiety Inventory (STAI) measures anxiety and distinguishes it from depressive syndromes. It has two subscales: the State Anxiety Scale evaluates the current state of anxiety, asking how respondents feel "right now," and Trait Anxiety Scale evaluating relatively stable aspects of "anxiety proneness". The STAI has 40 items, 20 items allocated to each subscale, with each item scored on a 4 point Likert scale. The subscale scores shown are averages of the items in the subscale ranging from 1.0 to 4.0, with a higher score indicating a greater level of anxiety.
- Participant Satisfaction With Consent Process [ Time Frame: Within 7 days of consent discussion ]A short study specific questionnaire and selected questions from the Quality of Informed Consent (QuIC) supplement questionnaire will query participants about their overall satisfaction with the consent process, helpfulness of information provided, and comprehension of key study-specific elements of treatment. Seven questions are included, each scored on a five point Likert scale. The overall score is the average of the item scores, ranging from 1.0 to 5.0, with a higher score indicating a higher level of satisfaction.
- Participant Information Location Time [ Time Frame: Within 7 days of consent discussion ]Participants are asked to identify select items within the consent document and the time taken to locate items is measured. Patients who were not able to identify a given section were assigned the maximum time allotted to find each section (180 seconds).
- Consent Rate on Parent Trial [ Time Frame: Within 7 days of consent discussion ]The consent rate is the rate at which participants provided consent to participate in the parent trial.
