Summary

Connection to Environment with Cognitive Therapy (CONNECT): A Single-Case Experimental Design Exploring Dissociative Experiences and Voices

Emerging empirical evidence has suggested that dissociation is a robust determinant of voice-hearing in psychosis, and that dissociation mediates the link between trauma and voices. Despite the emerging evidence-base, targeted therapeutic interventions focusing on dissociation remain largely untested.

The aim of the current study is to investigate whether targeting dissociation leads to improvements in distressing voices in people with a history of trauma. This will be done by delivering an eight session intervention called 'CONNECT' to six individuals within the Glasgow Psychological Trauma Service (GPTS) who hear voices, have experienced trauma and are dissociating. The intervention will focus on learning strategies to manage dissociation. It is hypothesised that reduced levels of dissociation will be associated with reduction in the frequency and distress associated with hearing voices.

This study will use a randomized multiple baseline single-case experimental design, meaning that participants will be randomly allocated to a baseline of two, three or four weeks and then will begin eight weeks of Connection to Environment Cognitive Therapy (CONNECT). As well as daily measures during baseline and intervention phases, there will be four assessment points (baseline, pre-intervention, post-intervention and follow-up). The study will take approximately three months plus follow-up one month after therapy ends. Individual levels of dissociation and voices will be compared during baseline and intervention periods using visual analysis and Tau-U.

This study will contribute to the evidence-based for dissociation interventions targeting distressing voices among this population. It serves to investigate the proposed mechanism in a clinical population using a therapeutic intervention. It will therefore inform clinicians of the effectiveness and feasibility of using such strategies in clinical practice and may have good generalizability to practice.
