Abstract Although anxiety has both dispositional and situational determinants, little is known about how individuals' anxiety-related sensitivities and their expectations about stressful events actually combine to determine anxiety. This research used Information Integration Theory and Functional Measurement to assess how participants' physical concerns sensitivity (PCS) and event expectancy are cognitively integrated to determine their anxiety about physical pain. Two studies were conducted – one with university students and other with anxiety clinic patients – in which participants were presented with multiple scenarios of a physically painful event, each representing a different degree of event probability from which subjective expectancies were derived. Independent variables included PCS (low, moderate, and high) and event expectancy (low-, medium-, high-, and non-probability information). Participants were asked to indicate their projected anxiety (dependent measure) in each expectancy condition in t...
