Abstract

Experiences of feeling empty are widely reported as deeply distressing for individuals, with research consistently demonstrating the relationship between emptiness and a number of mental health difficulties, as well as self-harm, and suicide. Clinicians and researchers alike have repeatedly called for further exploration of this concept. However, previously vague definitions, and a lack of validated and reliable measurement tools has consistently hindered our understanding of this experience. The following aims to contribute and advance this area of research. Part 1 – Conceptual Review The work presented in Part 1 encompasses a conceptual review of emptiness, clarifying the current definition of the experience and considering the similarities and differences to other similar concepts. The authors then consider the relevance to the field of mental health and presents the case for increased interest in emptiness. This is followed by consideration of the research areas in need of exploration, including the urgent need for psychometrically valid means of measuring emptiness, and the clinical implications of this work. Part 2 – Empirical Paper The project detailed in Part 2 involves the psychometric evaluation of a The Psychological Emptiness Scale (PES), a clinical measure developed from the first validated definition of emptiness set forth by Herron & Sani (2022). The psychometric properties of the measure are explored, with limitations and areas for future use highlighted. Part 3 – Critical Appraisal The final, Part 3, details a critical appraisal of the work undertaken and reflections of the primary author. This considers the bidirectional relationship between the author and the work, exploring how the identity and experience of the researcher influenced the project, and how the project has forever altered the researcher.
