Outcome Question or other assessment method Scale or interpretation
IMB element: Informational
 Perceived knowledge of home BP target “Do you know your personal BP treatment target?” Yes or No
 Able to report correct home BP target “What is your personal BP treatment target?” (___/___mmHg.) The home BP target was considered adequate if it was reported to be < 135/85 mmHg (diabetics < 135/75 mmHg).
 Home BP target set Mentioned in the checklist (intervention group) or in electric health record (control group). Yes, if any written target was found.
 Correctly set home BP target Mentioned in the checklist (intervention group) or in electric health record (control group). The BP target was considered adequate if it was set at < 135/85 mmHg (< 135/75 mmHg for diabetics).
 Perceived understanding of the pharmacodynamics of the medication Do you know how the medication prescribed to you works?” Yes or No
 Perceived knowledge about potential side effects of the medication Do you know the typical side effects of the antihypertensive medication prescribed to you?” Yes or No
 Patients reporting to have received written information on the medication Did you receive written information on the antihypertensive medication during the physician’s appointment?” Yes or No
 Patients reporting to have received written guidance on home BP measurements “Did you receive written guidance on how to carry out blood pressure measurements at home?” Yes or No
 Perceived uncertainty about the medication “Did you have any questions about the medication that were left unanswered?” Yes or No
IMB element: Motivational
 Perceived necessity of antihypertensive medication “How necessary do you find the antihypertensive medication for your elevated blood pressure?” 11-point numerical rating scale (0 = not necessary at all, 10 = very necessary).

 Perceived knowledge about how to act in case of medication side effects “Do you know how to act if you get medication side effects?” Yes or No
 Perceived knowledge about how to act in case that BP target is not reached “Do you know how to act if your blood pressure target is not reached?” Yes or No
