People with Personality Disorders (PD) often experience challenges to employment. Being prepared for work may be an essential part of overcoming these challenges. Identifying the obstacles and the extent one is ready for work may help in the planning of employment support for people with PD. The purpose of this thesis was to develop and evaluate the psychometric properties of the Preparedness for Employment Scale for people with Personality Disorders (PES-PD); the first employment-related scale for measuring preparedness for employment for PD. Chapter 1 presents background literature on PD and employment, including PD employment interventions and the importance of validated measures. The first study was a systematic review (Chapter 2) assessing the literature for PD and employment scales; the results showed a lack of appropriate PD scales. Consequently, this thesis conducted two studies; focus groups and an e-Delphi to develop the underlying construct of preparedness for employment and explore potential content to inform a new scale (Chapter 3). A 57-item version of the PES-PD was produced and then piloted (n=109) for its content and face validity in Study 4 (Chapter 4). The results of the pilot study provided a 35-item PES-PD. The final study conducted construct validity and internal consistency on the 35-item PES-PD (n=650) (Chapter 5). The results demonstrated a 3- factor model: Interpersonal (IV), Emotional Regulation (ER), Vitality (V), with good construct validity and internal consistency (Cronbach’s a = .74 [full scale], a = .85 , a = .74, and a = .77 [subscales respectively]). These findings suggest a promising self-report scale demonstrating promising psychometric properties. The PES-PD should be considered for use as an outcome measure, in the planning of employment treatment for PD, and to identify appropriate timing into work. Future research will involve further psychometric evaluation and assessing the clinical utility of the PES-PD.
