The relationship between hypertension and related biological, psychological, and social variables among patients diagnosed with hypertension was investigated utilizing the biopsychosocial model. Fifty-four participants from one outpatient private medical office were administered a demographic form, the Beck Anxiety Inventory (BAI), the Health Adherence Behavior Inventory (HABIT), the Inventory for Cognitive Distortions (ICD), and the Multidimensional Scale of Perceived Social Support (MSPSS). Results indicated that the participants' use of caffeine positively correlated with their high blood pressure readings. In addition, participants who reported having significant social support engaged in more health promoting behaviors. These findings were consistent with the hypotheses. Limitations of this research and directions for further research are discussed. These findings may have indications for primary care physicians, as they may better understand factors related to hypertension.
