This thesis explores the connected areas of compulsive buying and compulsive hoarding. The study is divided into two main sections. The first section is a critical review of the empirical evidence of treatments for compulsive buying undertaken through a detailed search and examination of published literature. The second section presents a research report of a single case experimental evaluation of cognitive-behavioural treatment of compulsive hoarding. Section 1 Literature Review: The current paper describes and critically reviews pharmacological and psychotherapeutic treatment studies of compulsive buying (CB). Current conceptual and theoretical issues surrounding the classification and conceptualisation of CB are discussed. The prevalence, epidemiology and comorbidity of CB with other psychiatric disorders (particularly compulsive hoarding) are described. Each published treatment study of compulsive buying is critically reviewed in terms of its methodological design and findings. The limitations of the current evidence base for the treatment of compulsive buying are drawn in terms of conceptualisation/classification, measurement, and sampling methods. Recommendations for future CB outcome research are provided. Section 2 Research Report: The current study describes an Object-Affect Fusion (OAF) informed Cognitive- Behavioural Therapy (CBT) intervention with a 63-year old woman with compulsive hoarding. A single-case experimental design time-series analysis was employed on 2-years of patient daily diary data relating to cognitive, behavioural and emotional factors in the lived experience of a compulsive hoarder. The patient showed statistically significant increases in incidence, frequency and volume of discard as a result of the intervention. Clinically reliable changes on a range of clinical outcome measures, including depression, general mental health, and compulsive acquisition and saving were noted. Visual clutter ratings showed reliable change in the upstairs area of the home only. Additional domiciliary visits as part of treatment protocol did not lead to increases in discard. Patient self-reported hoarding related cognitions, behaviour and affect showed statistically reliable reductions with exception of depression and shame. Results of the study provide preliminary evidence that OAF informed CBT interventions have clinical utility in the treatment of compulsive hoarding. Methodological limitations of the study, suggestions for future research and implications for clinical practice are discussed.
