Bullying is a matter of significant concern in the Cypriot educational setting. Teachers usually report their difficulties in understanding bullies and their anxiety to find effective ways to deal with them. This project investigated the self-concepts of a sample of nine boys identified as bullies at the end of primary schooling in Nicosia, Cyprus. The bullies' self-concepts were examined by the use of two instruments, namely, the "Butler Self-image profile for children" (SIP-C), which is derived from Personal Construct Theory, and the "Harter Self-perception profile for children" (SPPC), derived from Self-concept Theory. The results reveal that the bullies who participated in this study understood that their behaviour was usually inappropriate. Their self-perceptions varied across a number of dimensions, indicating the need to examine the complexity of their view of themselves as part of any attempt to seek to implement behavioural change.
