There is evidence of an association between hoarding (a tendency to acquire an excessive number of objects, which are stored in a disorganised, problematic manner) and psychosis (experiencing symptoms such as hallucinations, delusions, and thought disorder). However, the strength and the nature of the association between hoarding and psychosis is unclear. For example, we do not know whether psychotic experiences lead to the development of hoarding, whether hoarding leads to the development of psychotic experiences, or whether both are caused by a single underlying process, such as atypical social cognition. The aim of this PhD project is to further investigate the links between hoarding and psychosis in a series of studies, which will have important clinical implications.
Phase One of the PhD will involve analysing large datasets from general population studies of the prevalence of mental health problems, to investigate whether hoarding is associated with specific symptoms of psychosis.
The aim of Phase Two of the PhD will be to conduct experimental research investigating why the associations between hoarding and specific psychotic experiences identified in Phase One exist.
The aim of Phase Three of the PhD will be to investigate how the presence of psychotic symptoms may influence the effectiveness of current hoarding interventions.
Throughout the PhD, there will be an emphasis on engaging in open science practices, so that rigorous, reproducible research is generated.
