Student thesis: Doctoral ThesisDoctorate in Clinical Psychology


The first chapter of this thesis comprises an Extended Literature Review which provides a comprehensive overview of a novel imagery-competing intervention for reducing intrusive trauma memories. The interventions development and its translation from laboratory to clinical settings ('bench to bedside’) is considered with a critical review of the evidence from experimental and clinical studies. Recommendations are provided for future research.

The second chapter of this thesis outlines a Large Scale Research Project which aimed to examine the feasibility and acceptability of this brief imagery-competing (visuospatial) intervention with parents experiencing intrusive memories following their child's discharge from intensive care. This study used a single-arm, mixed-methods design. Data was collected remotely through self-report measures at multiple timepoints and semi-structured
interviews. The results and implications of these are discussed with recommendations for future research.

Thesis embargoed until 31 December 2026.
