Arguments have been made for dimensional models over categorical for the classification of personality disorder, and for the five-factor model (FFM) in particular. A criticism of the FFM of personality disorder is the absence of measures designed to assess pathological personality. Several measures have been developed based on the FFM to assess the maladaptive personality traits included within existing personality disorders. One such example is the Five-Factor Obsessive-Compulsive Inventory (FFOCI). The current study applied item response theory analyses (IRT) to test whether scales of the FFOCI are extreme variants of respective FFM facet scales. It was predicted that both the height and slope of the item-response curves would differ for the conscientiousness-based scales, due to the bias towards assessing high conscientiousness as adaptive in general personality inventories (such as Goldberg’s International Personality Item Pool; IPIP). Alternatively, the remaining FFOCI scales and their IPIP counterparts were predicted to demonstrate no significant differences in IRCs across theta. Nine hundred and seventy-two adults each completed the FFOCI and the IPIP, including 377 undergraduate students and 595 participants recruited online. A portion of the results supported the hypotheses, with select exceptions. Fastidiousness and Workaholism demonstrated the expected trends, with the FFOCI providing higher levels of fidelity at the higher end of theta, and the IPIP demonstrating superior coverage at the lower end of theta. Other conscientiousness scales failed to demonstrate the expected differences at a statistically significant level. In this context, the suitability of IRT in the analysis of rationally-derived, polytomous scales is explored.

Background: Borderline personality disorder (BPD) is a psychiatric diagnosis characterized by emotional and behavioural instability, and impaired ability to maintain relationships. Previous research has demonstrated an association between BPD and insecure attachment style. It has been argued that BPD is a disorder of attachment, with insecure attachment being associated with inadequate capacity to represent mental states, or to “mentalize”. There is evidence that people with BPD are impaired in their capacity to mentalize in the context of attachment relationships. The term “mentalization” encompasses a broad range of processes including metacognition. There is a theoretical basis for metacognitive deficits in BPD. However, there is a lack of empirical evidence regarding the role of metacognition in BPD and its relationship to adult attachment style. Method: Participants with BPD were recruited from Community Mental Health Teams, Clinical Psychology and a Dialectal Behaviour Therapy (DBT) service within NHS Highland. A comparison group of participants without BPD were recruited from the Clinical Psychology service, having been referred for symptoms of depression. Both groups were administered the Relationship Scales Questionnaire (RSQ)(a self-report measure of attachment); and a short version of the Metacognitions Questionnaire (MCQ-30). Severity of clinical symptoms and current mood was assessed using the Clinical Outcomes in Routine Evaluation (CORE) and the Hospital Anxiety and Depression Scale (HADS). Results: Participants with BPD scored significantly higher than those without BPD on the attachment-anxiety and attachment-avoidance dimensions of the RSQ. The BPD group also endorsed MCQ-30 items more than the comparison group. There was a significant difference between the groups on the MCQ-30 total score and four of the five subscale scores. There were significant positive correlations between attachment dimension scores and metacognition subscales. The strongest associations were between attachmentanxiety and “uncontrollability and danger” and “need to control thoughts” subscales of the MCQ-30. Only metacognition was predictive of current mood and distress levels. Conclusions: The results of this study show that people with BPD report high attachment-avoidance and attachment-anxiety in their relationships, relative to a non-BPD, depressed comparison group. These findings are consistent with the existing literature regarding the profile of attachment in BPD. This study also found that people with BPD also have more maladaptive metacognitions than people with symptoms of depression. An association between self-reported adult attachment style and maladaptive metacognitiion was demonstrated in the present study. Maladaptive metacognitive strategies and beliefs potentially contribute to maintenance of depressed and anxious mood, as well as broader symptoms of distress.

The study investigates the process of recovery for people diagnosed with personality disorder. This is related to the application of the new meaning of recovery from mental illness as explored by members of The Haven which, as the service setting for the study, addresses the problems of a client group that suffers significant social exclusion, known to impact on demand for health and other public services. It aims to examine efforts which attempt to reverse this social exclusion as an aspect of the recovery process. An earlier inquiry by the author yielded a new understanding of the diagnosis of personality disorder as defined by service users, and contributed to a change in the national agenda when the Department of Health responded by providing new national guidance and funding for pilot projects throughout the country. This resulted in The Haven, the service context for this current study. As yet, internationally, there is no agreed rationale of recovery for those diagnosed with personality disorder and few researchers have sought the views of service users regarding the issue. The following study is the first internationally known research about personality disorder and recovery. A Participatory Action Research approach was chosen for this study and The Haven Research Group, comprised of the author and Haven clients, formulated proposed research questions and conducted Focus Groups and Individual Client Interviews with 66 participants, over a period of three years. The group has been concerned with the effectiveness of The Haven as a recovery tool from the perspective of service users and carers. An examination of emerging themes, and the interplay between themes, gives insight into what participants consider to be the key steps to recovery for someone with a personality disorder diagnosis. From this thematic analysis a map is proposed of the journey of recovery for people with the diagnosis. Findings offer contributions to knowledge in terms of the service model and propose a new construct regarding recovery in personality disorder. This is defined as a journey of small steps highlighting recovering as a process, rather than recovery as a goal, leading to the emergence of the new concept of Transitional Recovery. As an alternative to the historically sequential path of rehabilitation and proposed recovery, this study offers a new, socially inclusive way of working with people who have a personality disorder diagnosis where they may choose to retain a haven while continuing to develop and progress on their chosen path in the wider world.

Women interpersonal chronic trauma survivors are frequently misdiagnosed with borderline personality disorder (BPD) or post traumatic stress disorder (PTSD), which often results in mistreatment. Neither PTSD nor BPD adequately describes the unique character alterations observed among those exposed to prolonged early childhood trauma.  Researchers suggest survivors of interpersonal and chronic trauma should be subsumed under complex PTSD (CPTSD)(MacLean & Gallop, 2003).  The primary purpose of this study was to test the validity of complex PTSD as a construct. MANOVA, ANOVA, chi- Square, and independent samples t- Tests were utilized to test hypotheses. Results revealed that women who experienced higher frequencies of trauma met more CPTSD criteria and had higher mean base rate scores on the Major Depression, Depressive, Avoidant, Masochistic, Anxiety, PTSD, and Borderline scales of the MCMI- III than women who experienced fewer traumas. Additionally, findings suggest that the Major Depression, Depressive, Anxiety, PTSD, and Borderline scales may highlight differences among women interpersonal trauma survivors who meet five of six CPTSD criteria versus those who meet full CPTSD diagnostic criteria. Lastly, the mean Borderline scale score for women who met full CPTSD diagnostic criteria was below the cutoff for personality traits. Overall, these findings provide evidence and validation for the distinction of CPTSD from BPD and PTSD.

Traditional conceptualizations of psychopathy highlight the importance of affective features of the syndrome in perpetuating social deviance. However, little research has directly investigated the callousness that psychopathic offenders display toward society and their victims. The current study investigated the roles of empathy and alexithymia in psychopathy among male and female incarcerated offenders, particularly in distinguishing psychopathy from antisocial personality disorder. Gender differences were also investigated. Regarding empathy, as predicted, group differences were largest between psychopathic and non-psychopathic offenders; no reliable differences emerged between psychopathic and APD-only offenders. In contrast, alexithymia robustly distinguished between offenders with prominent psychopathic traits, those with only APD, and those with neither condition. Psychopathic females unexpectedly exhibited slightly higher levels of alexithymia than their male counterparts, while empathic deficits were relatively consistent across genders. These findings are discussed in terms of improving assessment methods for the accurate identification and treatment of offenders with prominent psychopathic features.

L’objet de la thèse vise à étudier l’impact du type d’attachement et de la maltraitance sur les troubles de la personnalité d’une population de patients toxicomanes et recevant un traitement de substitution. Notre échantillon est constitué de 140 patients dépendants de drogues toxiques et placés sous traitement de substitution : dans cet échantillon, 70 femmes représentent le groupe expérimental et 70 hommes représentent le groupe témoin.Nous avons utilisé le CASRS (Child Abuse Self Report Scale) pour évaluer les événements traumatiques subis au cours de l’enfance, le MCMI (Millon Clinical Multiaxial Inventory) pour l’évaluation des troubles de la personnalité et l’ASQ (Attachement Scale Questionnaire) pour mesurer le type d’attachement. Nos résultats révèlent qu’il existe des spécificités en fonction des genres. Plus de maltraitance dans l’enfance, davantage d’attachement insécure, plus de troubles de la personnalité ainsi qu’un contexte social-familial particulier chez les femmes ont une importance étiologique. Ces différences épidémiologiques ont un impact sur la gravité de la toxicomanie (surtout en matière de violence psychologique et physique).Ces résultats devraient sans doute nous inciter à revoir nos stratégies de soins pour tenir davan-tage compte d’approches plus spécifiques. / The subject of our work was to study the influence of type of attachment and maltreatment on personality disorders in a population of patients addicted to drugs who receive replacement therapy. Our sample consisted of 140 patients with a diagnosis of toxic drug addiction substitu-tion treatment, including 70 women who represent the experimental group and 70 men who represent the control group. To evaluate the traumatic events in childhood, we used the CASRS (Child Abuse Self Report Scale), for assessing personality disorder we used MCMI (Millon Clinical Multiaxial Inventory) and finally the ASQ (Attachment Scale questionnaire) to meas-ure the type of attachment. Our results show that there are significant differences between males and females. A higher occurrence of abuse during childhood, demonstrates insecure at-tachment, more comorbid personality disorder and a socio-familial especially among women, which may have etiological significance. These epidemiological differences have an impact on the severity of substance abuse (more importantly the emotional and physical abuse). There-fore, these results encourage us to rethink our strategies of care for more specific approaches while handling such patients.
