Critically evaluate the extent to which a patient's beliefs influence their experience and response to health care. Our personal beliefs influence our health behavior, either positively or negatively. Health beliefs have been linked to adoption and have been measured using a number of models. For example, Bish et al. (2000) used the Health Belief Model (HBM) and the Theory of Planned Behavior (TPB) to predict the uptake of a routine cervical smear. Personal models refer to the representations that patients have of their illness and include knowledge, beliefs, experiences and emotions. regarding their state of health (Petrie and Weinman, 1997; Skelton and Croyle, 1991). In self-regulation theory, they are assumed to play an important role in determining a person's response to a health threat and their subsequent health-related behavior (Leventhal, Leventhal, & Contrada, 1998 ; Leventhal, Nerenz and Steele, 1984). Consistent with self-regulation theory, personal models of diabetes have been shown to be predictive of diet and, to a lesser extent, exercise of self-management in older adults with diabetes (Hampson, 1997a ). The association between health beliefs and intentions or actual performance of health behaviors has been extensively examined within the theoretical framework of social cognitive models such as the health belief model (e.g. e.g. Rosenstock, 1974) and the theory 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 with elements of theories of social cognition. However, personal models are unique in that they are based on empirical data and come from studies conducted with patients.
