Epistemic assumptions: Understanding self and the world (a note on the relationship between identity style, world view, and constructivist assumptions using an Australian sample)

Berzonsky (1994) has investigated the role that personal epistemological as sumptions play in the construction and revision of self-identity. He develo ped the Constructivist Assumption Scale (CAS) to measure the constructivist assumptions of persons, relating this to identity style as measured by the Identity Style Inventory, 3rd edition. Botella and Gallifa (1995) have out lined a constructivist model of epistemic development moving from positivis m to constructivism (measured by the CAS), and preferred worldviews moving from mechanism to organicism (measured by the Organicism-Mechanism Paradigm Inventory). This study investigated the relationship between identity styl e, preferred worldview, and level of constructivist assumptions. Results in dicate a significant positive relationship between the constructivist assum ptions and people having an information-oriented, self-identity style, and significant negative relationships between the constructivist assumptions a nd preferred worldview for individuals with a normative oriented identity s tyle. Age was significantly related to worldview, but not to the constructi vist assumptions of the individuals. The theoretical implications of these findings are discussed, including whether people have different epistemic a ssumptions when describing self versus those used when describing the world . An additional measure is suggested which may relate findings to Kelly's ( 1991) notions of aggressiveness and hostility.
