The paper presents original study and its findings concerning the possibility of using personality traits and motivational traits as predictors of social competence. According to the findings, motivational traits, including social anxiety and managerial and organisational interests, correlate highly with social competence in situations of social exposure and requiring self-assertion. Hence, motivational traits are highly useful predictors of social competence in both types of social situations. Moreover empirical findings point out that in order to increase the accuracy of estimating social competence both personality traits and motivational traits should be considered. Measurement of both traits estimates the level of social competence more accurately than the measurement of personality traits. Implication for occupational selection is discussed.
