Thematic Analysis of Autobiographical Dissociation Scripts in Borderline Personality Disorder

Dissociation is a complex trans-diagnostic phenomenon, which ranges from normative to pathological. There are multiple ways of measuring and categorising dissociation, and different theories as to the aetiology and function of dissociation in psychological disorders. People with Borderline Personality Disorder (BPD) experience more dissociation than healthy controls and other personality disorders, and dissociation is associated with other key features of BPD. Despite this, dissociation in BPD is poorly understood. It is unclear which types of dissociation manifest in BPD, in which situations, and the function that dissociation achieves. The aim of this study was to investigate the form and function of dissociation in BPD, by identifying themes across personal narratives. A thematic analysis was performed on narratives of dissociative experiences assessed within a script-driven imagery approach. The predominant forms of dissociation were depersonalisation and derealisation....Show moreDissociation is a complex trans-diagnostic phenomenon, which ranges from normative to pathological.

Despite this, dissociation in BPD is poorly understood. It is unclear which types of dissociation manifest in BPD, in which situations, and the function that dissociation achieves. The aim of this study was to investigate the form and function of dissociation in BPD, by identifying themes across personal narratives. A thematic analysis was performed on narratives of dissociative experiences assessed within a script-driven imagery approach. The predominant forms of dissociation were depersonalisation and derealisation. Dissociation occurred in interpersonal and threatening situations, tended to follow negative affect, and was accompanied by physical reactions consistent with sympathetic nervous system activation. Dissociation functioned as psychological escape from internal experiences or external situations. These themes are discussed within the context of prominent theories of BPD and dissociation. These findings are in line with the idea that dissociation in BPD acts as a protective mechanism against high sensitivity and reactivity to affective and interpersonal experiences in the place of normative regulation skills. This paper concludes that dissociation in BPD offers psychological escape from intolerable experiences, and is related to a low threshold for threat perception and threat response mobilisation.Show less
