Fifth, Andersen (1968) developed a model of health care utilization (Figure 3) which
looks at three categories of determinants: 1) predisposing characteristics. This category represents the proclivity to utilize health care services. According to Andersen, an individual is more or less likely to use health services based on demographics, position within the social structure, and beliefs of health services benefits. An individual who believes health services are useful for treatment will likely utilize those services; 2) enabling characteristics.
