An investigation of the relationship between intimate partner abuse and suicidality: a test of a model

Objectives This thesis aimed to investigate the relationship between intimate partner abuse and suicidality, to deepen our understanding of the factors and mechanisms involved in increasing suicide risk in this group. This investigation was carried out using the framework of the Integrated Motivational-Volitional (IMV) Model of Suicidal Behaviour (O’Connor, 2011), and this research aimed to act as a test of this theoretical model. Method In order to achieve the above objectives, two major studies were conducted. These were prospective studies, with Study one being exploratory and utilising a large scale survey design, and Study two carrying out an in-depth investigation. These studies utilised a general population sample consisting of both males and females, and compared those with and without experience of intimate partner abuse. Both studies are reported over two chapters, one focusing on the relationship between intimate partner abuse and suicidality, and the other reporting the testing of the IMV Model. Results This research identified a number of key aspects relating to intimate partner abuse which are involved in increasing suicide risk within this group, such as the frequency of the abuse experienced, levels of control within the abusive relationship, and severity of stalking and harassment behaviours experienced. Investigation of the key elements of the IMV Model revealed that perceptions of internal entrapment play a significant mediating role in the relationship between intimate partner abuse and suicidality. In addition, social support and future thinking were found to act as moderators of this relationship. Conclusions This research makes a valuable contribution to the understanding of intimate partner abuse and suicidality, and highlights a number of important issues with regards to the conceptualisation and measurement of IPA. It has also identifies the importance of considering aspects such as stalking, perceptions of internal entrapment, and levels of control within relationships, when investigating suicidality within this group. This research used the context of IPA and suicidality to test the IMV Model, which has significantly increased out understanding of suicidality in relation to IPA. The IMV Model was shown to be a useful framework for understanding this relationship, however limitations of the model were identified. Further research is needed to test the model further and to explore the relationship of some of the elements within the context of IPA and suicidality
