List of Changes

1. Modifications to Questions

Rationale: Splitting Question 2 on the Home Tap Water Questionnaire into four parts will reduce unnecessary water collection and in testing did not increase the average time burden on pilot testing as most participants do not use water softeners or water filtration systems.

Att 10A1_Home Tap Water Questionnaire: Split question 2 (1 question) into two questions each with a sub-question among those responding affirmatively (4 total questions).

Previously Approved Question	Proposed Questions and Rationale
2.) Do you have a water softener or water filtration system in your home/apartment? YES……………..........……………………….1 NO…………………….........…………………2 REFUSED………………........................7 DON’T KNOW………………….........................9	Rationale: Splitting question 2 into four parts will reduce unnecessary water collection and in testing did not increase the time burden on pilot testing as most participants do not use water softeners or water filtration systems. 2.)

2. Changes and clarifications in instructions and/or procedures to simplify information collection

Att 4A_ Telephone Recruitment and Screening Script

Rationale: The amount of home tap water that needs to be collected is larger than previously thought (~120 ml vs. 10 ml). As initially planned, this complicated procedures. Thus, the Home Tap Water Questionnaire will be administered at the end of the telephone recruitment and screening rather than at the initial visit and the participant will be asked to bring a sample of home tap water with them to the initial visit. Additional clarifications and their rationale listed below.

Modification	Rationale
Added the following instructions to the clinic manager: “IF THE PERSON IS ELIGIBLE AND SCHEDULES A CLINIC VISIT, ADMINISTER THE HOME TAP WATER QUESTIONNAIRE TO DETERMINE IF THEY SHOULD BRING IN A WATER SAMPLE.”	The home tap water questionnaire will be administered at the end of telephone recruitment after the person schedules a clinic visit rather than at the initial visit to save costs related to mailing water specimens: The amount of water required for analysis is about 1/2 cup (~120 ml) which is much greater than previously expected (10 ml).
Information regarding urine collection deleted from the form.	Participants who are not in the Sub Study will not be collecting urine.
The following sentence “Three of these days must be weekdays and one must be a weekend day” will be added after “The day prior to each telephone interview participants will be asked to collect samples of all the salt they add to food in home cooking and at the table.”	To clarify participant expectations and increase adherence to study procedures
Deleted the phrase “and I’ll mail you a written description of the study and a consent form to read before the visit”	All of the piloted participants scheduled an initial clinic visit within 5 days of the telephone call, most the next day. The participants receive the study description and consent form at the initial visit. The consent form will be read to the participant and any questions answered.

Att 8 Study Orientation for Non-Sub Study Participants – modification of text

Rationale: On Att 8 and Att 9, the text orienting participants to the study components has been modified so that all of the study components are described on these forms and reviewed by the study manager. The participants are then provided written copies of the corresponding information collection forms and instructions for review at home. In addition, the scheduling for the dietary recall which was a part of this form will now be collected on a separate form (Att 8a) to be sent to the University of Minnesota Nutrition Coordination Center.

Modification (in red as applicable)	Rationale
Deleted information on urine collection.	According the approved ICR for 0920-0982, Non Sub Study Participants will not collect urine.
The following sentence “One of these days must be a weekend day; the other three will be weekdays” will be added.	See Att_4A: Screening and Recruitment. To clarify participant expectations and increase adherence to study procedures.
Added Information from the instructions, Att 12 B Food Record Instructions	This will assist the clinic manager and improve the flow of the initial clinic visit – rather than having to switch between forms, the food record collection instructions are also now included on this form. All applicable instructions are consolidated on one form. The clinic manager will then give the Food Record Instructions and Form to the participant to take home.
Deleted Scheduling Information	Scheduling for the 24-hour dietary recall is moved to a separate form for ease in EMAILing - See Att_8a Dietary Recall Scheduling Form. The clinic manager will provide the participant with a calendar with the agreed upon dates for the 24-hour dietary recall interviews and the duplicate salt collection dates.

Att 9 Study Orientation for Sub Study Participants – modification of text

Rationale: On Att 8 and Att 9, the text orienting participants to the study components has been modified so that all of the study components are described on these forms and reviewed by the study manager. The participants are then provided written copies of the corresponding information collection forms and instructions for review at home. In addition, the scheduling for the dietary recall which was a part of this form will now be collected on a separate form (Att 8a) to be sent to the University of Minnesota Nutrition Coordination Center.

Modification (in red as applicable)	Rationale
The following sentence “One of these days must be a weekend day; the other three will be weekdays” will be added.	See Att_4A: Screening and Recruitment. To clarify participant expectations and increase adherence to study procedures.
Added Information from the instructions for the Att 12 B Food Record Instructions	This will assist the clinic manager and improve the flow of the initial clinic visit – rather than having to switch between forms, the food record collection instructions are also now included on this form. All applicable instructions are consolidated on one form. The clinic manager will then give the Food Record Instructions and Form to the participant to take home.
Deleted Scheduling Information	Moved to a separate form for ease in EMAILing - See Att_8a Dietary Recall Scheduling Form. The salt collection date will be written on each packet given to the participant. The clinic manager will provide the participant with a calendar with the agreed upon dates.

Att 12A_Food Record Form

Modification (in red)	Rationale
Deleted ID field.	Participant ID is not necessary. Form is used by the participant to aid in recall and is NOT collected by study staff.
Total Amount Prepared (ONLY only for home prepared foods with salt added in preparation)	Clarify instructions for participants.

Att 15A_24-Hour Urine Collection Form

Modification (in red)	Rationale
Return the urine specimen bottle(s) and this sheet to the clinic the day after collection	Per protocol, participants will be scheduled to come to the clinic the day after their 24 h urine collection is scheduled.

Remember to take the salt shaker with you wherever you go so that you’re able to use it if you eat at work, restaurants, and other places away from home,	Additional instructions provided to be consistent with recording information about salt use on the baggie labels for duplicate salt collection.
Salt added in preparing food at home Use the Study Salt Supplement provided to you in the study container whenever you add salt to food in home cooking. If someone else in your home is preparing a food that includes salt, make sure they use the salt provided by the study. Please also provide duplicate samples of all salt added to your food in home cooking. Any salt added to food prepared outside your home does not need to be collected. Put the same amount of salt added to the dish in a bag with a white label immediately after adding salt to the dish. Record the date, name of the dish prepared and type of salt used (regular salt including sea salt, iodized salt, non-iodized salt, and kosher salt; or another type such as lite salt or salt substitute for your first collection; “Study Salt” for the three subsequent collections) on the bag label. Record the total amount of the dish you prepared on the ‘Food Record Form’. Each dish you add salt to in your home cooking will have a separate bag of duplicate salt so you may use multiple white-labeled bags for one collection day. For your first collection day you will use your own salt. After you receive the Study Salt, (when you drop off your first urine collection) please use it whenever you add salt to food in home cooking. If someone else in your home is preparing a food that includes salt, make sure they use the salt provided by the study.
