Common and distinguishing historical, criminal and current environmental and psychological characteristics in male inmates with a history of suicidal and/or non-suicidal self-injury

Abstract

Purpose Non-suicidal self-injury (NSSI) is distinguishable from suicide attempts (SAs) on a number of psychological and motivational factors. However, in corrective services settings, NSSI and SA are not clearly distinguished in assessment impacting on intervention. The purpose of this paper is to examine if any attributes differentiate lifetime history of SA+NSSI, NSSI and SA presentations in inmates who had recently been assessed in custody by a risk intervention team. Design/methodology/approach A comprehensive clinical assessment and file review was conducted with 87 male inmates (including a no self-injury control group) in two large correctional centres in New South Wales, Australia, to determine if three self-injury groups differ from the control group and if the three self-injury groups differ from each other across a range of static, trait, environmental and clinical characteristics. Findings The SA+NSSI group was most different from the control group (27/59 variables), and from the SA group (10/59 variables), predominantly across trait and clinical correlates. The SA group was least different from the control group (2/59 variables: suicide ideation, childhood physical abuse). Originality/value It was found that the presence of SA+NSSI history is an indicator of increased psychopathology. A history of SA only appears not readily associated with psychopathology. The self-injury subgroups reflected different clinical profiles with implications for risk assessment and treatment planning.
