Critically evaluate the extent to which the patient's beliefs influence their experience and response to health care. Our personal beliefs influence our health behavior both positively and negatively. Health beliefs have been linked to adoption and have been measured using a variety of models. For example, Bish et al. (2000) used the health belief model (HBM) and theory of planned behavior (TPB) to predict uptake of a routine cervical Pap test. Personal models refer to patients' representations of their illness and include knowledge, beliefs, experiences, and emotions regarding their health status (Petrie & Weinman, 1997; Skelton & Croyle, 1991). Within self-regulation theory, they are assumed to play an important role in determining a person's response to a health threat and subsequent health-related behavior (Leventhal, Leventhal, & Contrada, 1998; Leventhal, Nerenz, & Steele , 1984). Consistent with self-regulation theory, personal patterns of diabetes have been shown to predict diet and, to a lesser extent, exercise self-management among older people with diabetes (Hampson, 1997a). The association between health beliefs and intentions or actual performance of health-related behaviors has been extensively examined within the theoretical framework of social-cognitive models such as the health belief model (e.g., Rosenstock, 1974) and the of planned behavior (e.g. Ajzen, 1985). These theoretical approaches have a number of overlapping constructs ( Norman & Conner, 1996 ), and personal models also have similarities to elements of theories of social cognition. However, personal models are unique in that they are empirically based and originate in patient studies.
