Abstract
This study designed and validated an instrument for measuring sojourners' intercultural and everyday communication self-efficacy. Factor analysis of a Likert-type scale completed by Japan Exchange and Teaching (JET) Programme respondents (N = 213) identified a unidimensional-factor solution with 34-items loading (α=.95). It revealed negative, positive, and no correlation with existing scales that lent validity to the resulting Sojourner Self-Efficacy in Communication (SSEC) Scale. The authors present both the full scale and a shortened 8-item version (α=.86), and discuss ways the SSEC Scale offers new directions from which to explore issues of intercultural communication and cultural adaptation.
