Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participant recruitment brochures and posters with the advanced practice nurses' (APRNs) names/practice contact information were placed in practice waiting and examination rooms. Older adults self-referred for the study by calling the practice and making an appointment with the APRN. Recruitment was rolling during Sept. 2007 – June 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Exclusion criteria were less than age 60; health literacy score below 44 (6th grade); not currently prescribed antihypertensive medication; visual acuity of less than 20/100 (with corrective lenses, if needed); inability to meet independent-living and cognitive-functioning ability.

Reporting Groups
  Description
Education Intervention

PEP education intervention

Personal Education Program - Next Generation (PEP-NG) : Adults aged 60 and over with hypertension were randomized to usual care and education (intervention)groups. Both groups entered medication taking behaviors on the PEP-NG and answered questions related to knowledge and self-efficacy regarding adverse self-medication behaviors. The education (intervention) group received a tailored education program generated by the PEP-NG software and reinforced by the APRN.

Control

Control:

Adults aged 60 and over with hypertension were randomized to usual care and education (intervention)groups. Both groups entered medication taking behaviors on the PEP-NG and answered questions related to knowledge and self-efficacy regarding adverse self-medication behaviors. The control group met with the APRN after entering their data on the PEP-NG but did not receive a targeted and tailored education intervention.
