How we believe that intelligence is? Can intelligence be changed by effort? Is intelligence determined by nature? Wehave a belief that intelligence varies from person to person. Dweck defines such a belief as Implicit Theories of Intelligence(ITI). There are two theories in ITI. Those are incremental theory and entity theory. Incremental theory is a beliefthat I can change my intelligence. Entity theory is a belief that my intelligence can’t control by myself. Many pastresearches treat ITI as one factor. But recent researches treat ITI as two factors. Purposes of this study is to verify forreliability and validity about a two-factor Implicit Theories of Intelligence scale. Hierarchical factor analysis showed thatITI are stabled by one factor or two factors. But two-factor model is better than one factor model, because all two factormodel’s paths are significant. And correlational analysis showed that different patterns of convergent validity. Theseresults mean that incremental theory and entity theory has different quality. Results of two analysis means that two-factorimplicit theories of intelligence scale is better than past one factor scale.
