Abstract The effects of Knowledge, Motivation, and Selected Perceptions on Levels of Compliance Among Hypertensive Adults Brenda Buseman Andersen 1986 Questionnaires were designed and administered to a nonrandom sample of 36 hypertensive adults, attending a blood pressure screening clinic at a hospital-based wellness center in a rural Midwestern state. The questionnaires obtained information which attempted to describe the effects of knowledge, motivation, and selected perceptions on levels of compliance among hypertensive adults. The independent variables were selected aspects of the Health Belief Model including perceived severity of hypertension, perceived barriers of antihypertensive therapy, perceived benefits to antihypertensive therapy, knowledge about hypertension, and motivation about health in general. The dependent variables were compliance levels with various aspects of prescribed antihypertensive therapy including exercise activities, diet modifications, and antihypertensive medication. Fifteen null hypotheses were generated. The major finding at the .05 level of significance was that there was a relationship between perceived barriers about antihypertensive therapy and compliance with medication.
