Abstract
The aim is to investigate if the adherence of patients with hypertension
will improve, when General Practitioners (GP) communicate about the patients
illness representations and action plans.
Communication is manipulated in experimental conditions guided by two
stages of Leventhals Self-Regulatory Model of Illness: (1) illness
representations; (2) an action plan or coping procedure. In these stages
the processing occurs both at a cognitive and an emotional level. As interaction
between stages proceeds in both directions, an intervention aiming at
a certain stage will influence the whole Self-Regulatory Model of Illness.
Three conditions were planned that each consists of a 15 minutes conversation
between a confederate (a GP-trainee) and a patient. Condition 0 acts as
a care-as-usual condition; Condition I ("mind-switch") aimed
at stage 1 about illness representations; Condition II, ("action-plan"),
aimed at stage 2.
Hundred-and-twenty-six patients with hypertension using anti-hypertensive
medication were randomly assigned to the three conditions.
Three GP-trainees performed each of the three conditions. Consultations
were video-recorded. Patients filled in questionnaires immediately before
and after the experimental consultation (assessing illness representations,
stages of change, adherence & quality of care). Three months later
they received a questionnaire at home (assessing illness representations,
stages of change, adherence & quality of care). In addition, medication
refill compliance and blood-pressure measurements were obtained. The findings
of the experiment will be presented during the conference.
