This study examined the relationship between importance ratings of positive and negative personal attributes and depressed mood. Undergraduate psychology students (n = 115) completed the Beck Depression Inventory-II and made self-referential ratings on several adjectives. Participants subsequently indicated how important it was for them to possess or fail to exhibit each of these traits. The results demonstrated that the perceived lack of important positive traits was related to increased depressed mood whereas not exhibiting important negative traits was associated with less depressed mood. Moreover, depressed mood was related to the degree to which respondents were certain about their endorsement of the traits. The implications of these results are discussed.
