Abstract
The purpose of this study was to develop Revised Interpersonal Intolerance of Ambiguity Scale (IIAS-R), which assessed the tendency with subscales for three types of people: first-time stranger, not-well-acquainted, and friend. Items for the scales were collected from self-report responses to an open-ended questionnaire. Scores for each subscale appeared to distribute normally. Internal consistency of the subscales was sufficiently high. Correlation coefficients between IIAS-R and social anxiety and dogmatism scales ranged from .52 to .22, which were statistically significant. Three-month test-retest reliability coefficients of the three subscales were .73, .70, and .66, respectively. The results demonstrated that the scale had good reliability and validity.
