We spend a large portion of our life at work, however that workplace is generally more suited for some than for others. There is a bias towards extraverted people in the design of the workplace which can have outright negative effects on the introverted population and as an extension, people with schizoid personality disorder. The purpose of the thesis was to identify areas which could be subject to change in the workplace in order to facilitate a larger population and increase the well-being of introverted people, particularly those with schizoid personality disorder (SPD). Data was collected through a questionnaire (N = 52) and the analysis presented evidence of a difference in how important the participants deem it that a workplace is designed for socialisation and how possible it is to work without interruptions from other colleagues. The results indicated a large difference between the more and less extraverted groups in how important and how possible it was to work without interruptions from their colleagues. The results also indicate a significant difference between how important they deem it that a workplace should be designed for socialisation. In conclusion the author suggests areas which can be improved in the workplace design to facilitate a larger group of the population and not just be beneficial to the extraverted population.

This thesis presents research aimed at examining rejection sensitivity in adolescent girls with borderline personality disorder (BPD) features. Although rejection sensitivity has been discussed more generally in the literature, few studies have identified how this construct may contribute to psychopathology in adolescence. There is also limited research regarding outcome behaviours that may be associated with high rejection sensitivity as well as factors that contribute to the manifestation of this construct. Here, this thesis aims to further the understanding of rejection sensitivity in adolescence and provide evidence to support the clinical utility of examining and offering treatment for this factor in youth presenting with BPD features. Although research has shown that BPD and high rejection sensitivity are strongly correlated, few studies have investigated the outcomes that may result from having this comorbidity. In the first paper of this thesis, disordered eating was examined as an outcome behaviour in a clinical sample of girls with BPD features. The results showed that girls who met diagnostic criteria for BPD had significantly higher disordered eating behaviour and that rejection sensitivity, operationalized as fears of abandonment, mediated this relationship. In the second paper of this thesis, the relationship between self-esteem, BPD features and perceived peer rejection was investigated in a longitudinal community sample of adolescent girls. We tested the sociometer hypothesis (Leary, 2005) that self-esteem served as a metric to detect the degree of belongingness in a group context. The results indicated that the relationship between BPD features and perceived peer rejection depended on self-esteem over time. Overall, the two studies presented in this thesis contribute to the knowledge regarding rejection sensitivity in adolescents with BPD features and explores correlates and outcomes of this relationship to aid in the identification of novel treatments to target and ameliorate rejection sensitivity in this population. / Thesis / Master of Science (MSc)

no / Background: Self-harm (self poisoning and self-injury) is broadly characterised as any act intended to harm one's own body, without a conscious intent to die. Research indicates that when practitioners encounter self-harm they often remain anxious, fearful, frustrated, and challenged about such individuals, principally because they are constrained to understand and respond to self-harm almost exclusively within a problematised discourse (Walker, 2006). That is, a problem that must be diagnosed and contained. Women who self-harm with a diagnosis of BPD are often portrayed as being risky, chaotic and their identity can be unstable. The aim of this study was to examine and explore the subjective experiences of women who self-harm with a diagnosis of BPD. Participants: Four women who had a history of self-harming behaviour with the diagnosis of BPD volunteered for the study. Method: Face-to-face, in-depth narrative interviews were undertaken and were analysed within a framework which drew upon aspects of the ¿performance¿ (Langellier, 1989; 2001) and ¿narrative thematic¿ approaches (Reissman, 1993). Findings: Two of the participant's accounts illustrate how their self-harming appeared to have affected their selfhood and sense of agency. They discuss how the external signs of self-harm may take over their identity and how others communicate and interact with them. Despite the problematic nature of self-harm implications for practice are highlighted which practitioners may draw upon in their work around self-harm.

Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits in (1) attention (Lees-Roitman, Cornblatt, Bergman, Obuchowski, Mitropoulou, Keefe, Silverman, & Siever, 1997), (2) memory (Bergman, Harvey, Lees-Roitman, Mohs, Margerm, Silverman, & Siever, 1998), (3) executive functioning (Cadenhead, Perry, Shafer, & Braff, 1999), and recently (4) neuromotor functioning (Neumann & Walker, 1999), similar to individuals with a diagnosis of schizophrenia. Furthermore, recent research suggests a link between neuromotor and cognitive functioning in schizophrenia spectrum disorders (SSDs) (Neumann & Walker, 2003). The current study is an extension of research on non-drug-induced neuromotor disturbances in individuals with SPD and examines how such disturbances covary with neurocognitive measures. Approximately thirty-three adults (18-65) were rated for SPD symptoms. Motor assessments included a computerized motor task and finger tapping test. Cognitive assessments included measures of attention, verbal and visual memory, and executive functioning. Consistent with previous research, the SPD group displayed significant right hand (left hemisphere) motor disturbances (i.e., increased force and force variability) compared to healthy controls after excluding all cases reporting a history of head injury. In addition, results indicate significant associations between motor, cognitive, and symptom variables. Consistent with previous research, neuromotor functioning and the relationships between motor and cognitive functioning varied as a function of Time of Day (TOD) of testing. Understanding the relationship between neuromotor and neurocognitive functioning may help elucidate the neural systems that contribute the symptoms characteristic of SSDs.

Researchers have previously identified substance use and borderline personality disorder as factors that increase risk for suicidal thoughts and behaviors. This study explored the relationship between these factors in samples of students and individuals seeking outpatient treatment. Supplemental data collected via the internet (MTurk) also looked at experiential avoidance (EA) with the Avoidance and Fusion Questionnaire for Youth. The Structured Clinical Interview for the DSM-IV, Alcohol Use Disorders Identification Test, Scale for Suicide Ideation, and Personality Assessment Inventory- Borderline Features Scale elicited information regarding severity and/or frequency of substance use, suicidal thoughts, and borderline features respectively. Additionally, the Psychiatric Diagnostic Screening Questionnaire was administered to the UNT sample. The UNT sample analyses indicate substance use moderates, strengthening, the relationship between borderline features and current suicidal thoughts. However, severity of suicidal thoughts was lower for individuals high in both borderline features and substance use disorder symptoms compared to those low in borderline features and high in substance use symptoms. The MTurk sample analyses suggest substance use functions as a mediator. A robust relationship existed between substance use severity and EA, showing substance use as a behavioral marker for EA. In conclusion, concurrent treatment of substance use and borderline personality features would be beneficial in reducing risk for suicidal thoughts. Further investigation into the role and utility of addressing EA is warranted.
