This article reports on a study carried out on the role constructs of forensic and nonforensic Learning Disability Nursing in relation to six binary themes. The aims were to identify if there were differences in perceptions of forensic learning disability nurses and nonforensic learning disability nurses in relation to the six binary themes of the role construct framework and then to establish if there were differences between the two groups of nurses. The method was a survey design with the sample drawn from high, medium and low security settings and nonsecure settings in the UK. From 400 questionnaires distributed, response rates of 46% and 49% were achieved from secure and nonsecure settings, respectively. The results indicate that the forensic nurses group show a significant difference between ranked scores on a number of themes but no significant difference was found between scores on one of the themes. The nonforensic nurses group also showed a significant difference between scores on a number of the themes but no significant difference was found between scores on a number of themes. Finally, the results of the between group analysis show a significant difference between forensic and nonforensic groups scores on several themes but these are few in number. The conclusions drawn are that whilst there is some support for the relevance of the themes in relation to learning disabilities in the forensic setting, there is less support for nonforensic settings.
