Abstract: | This paper addresses how social self‐esteem relates to self‐reported bullying behaviour among adult prisoners. It explores both level of self‐esteem and participants’ certainty of their self‐esteem. A total of 502 adult prisoners (285 men and 217 women) completed a self‐report behavioural checklist (Direct and Indirect Prisoner Behaviour Checklist) [Ireland JL. 1999. Aggres Behav 25:162–178] that addressed the level of bullying behaviour at their present institution. Prisoners also completed a questionnaire that measured social self‐esteem (Texas Social Behaviour Inventory) [Helmreich R, Stapp J. 1974. Bull Psychonomic Soc 4:473–475]. Four categories of prisoners were compared: bullies, victims, those who reported both bullying others and being victimised themselves (bully/victims), and those who were not involved in bullying behaviour. There were no significant differences among bully categories in total self‐esteem scores. Men reported significantly higher levels of self‐esteem than did women. There were no significant sex or bully category differences in certainty of self‐esteem. Self‐esteem was found to include a number of individual components that differed between the sexes. The findings are discussed, and directions for future research are suggested. Aggr. Behav. 28:184–197, 2002. © 2002 Wiley‐Liss, Inc. |
