People diagnosed with personality disorder present a longstanding challenge in the development and delivery of effective healthcare services. However, clinical outcomes are poorly understood and treatments have yet to be personalised.
This PhD study developed a longitudinal model to improve treatment delivery for complex needs, using a range of advanced quantitative modelling techniques - including Structural Equation Modelling, Latent Profile Analysis and causal modelling. Methods were applied to a novel dataset using routine clinical data in secondary services, and provide a preliminary first step in enabling services to better cater to individual need.
