A translation of the Rathus Assertiveness Schedule (Rathus, 1973) was tested for psychometric properties on two Swedish samples of college students. Scores from the first sample (n = 144) indicated high reliability for the original scale (Cronbach's alpha = .82) and an item analysis showed that the scale if shortened by six items had improved reliability (Cronbach's alpha = .84). This new scale, tested for validity on another sample (n = 28), showed acceptable discriminative validity. The shortened version is recommended for use in different kinds of settings.
