"Where did I park my car?" : a mixed methods investigation on mild cognitive impairment diagnosis in New Zealand : a thesis submitted in partial fulfilment of the requirements for the degree of a Doctor of Philosophy in Psychology at Massey University, Wellington, New Zealand

Mild cognitive impairment (MCI) is defined as an objective impairment in cognitive function which spares everyday functional ability. The syndrome is shrouded in controversy regarding definition, cut-off criteria, and clinical utility. Consequently, it is an uncertain label for the client being diagnosed by their healthcare practitioner. To date, minimal research in New Zealand has focused on MCI within specialist assessment services. Reasons for this paucity of literature will be discussed throughout this thesis. The current research aimed to identify how practitioners deliver and perceive cognitive impairment diagnosis, and examine how clients respond to receiving this diagnosis. Client experiences were framed within the common sense model (CSM). This theory originates from health psychology, where coping behaviour is said to be influenced by the cognitive representations that a person has about their condition. Although the framework is previously discussed in relation to chronic illness, international researchers have started to examine the utility of the model in explaining MCI diagnosis response. Given this context, the CSM framework guided the client-focused components of this thesis. In Study One, 57 practitioners who diagnose cognitive impairment completed a questionnaire on labels applied to MCI and beliefs about the value of diagnosis delivery. Responses were analysed using content analysis to gain an impression of professional practice. Cognitive disorder - not otherwise specified (CD-NOS), early dementia, and normal ageing were reported to additionally label the symptoms of MCI in clinical practice. In Study Two, client responses were examined in a small clinical sample (N = 9) diagnosed with MCI and CD-NOS. Participants were interviewed twice within six months of initial diagnosis. Interpretative phenomenological analysis was used to gain insight into how people cope and make sense of their diagnosis over time. Descriptive analyses were also undertaken with a subset of Study Two data to examine changes and differences in coping strategies over time. Findings suggest that participants may not see their diagnosis as an illness or significant health threat in the first six months following diagnosis. This prompts a question on the suitability of an illness model with reference to diagnosis response. Findings from this research add to the literature by highlighting practice associated with an evolving form of clinical diagnosis in NZ

On approximation rates for boundary crossing probabilities for the multivariate Brownian motion process

Motivated by an approximation problem from mathematical finance, we analyse the stability of the boundary crossing probability for the multivariate Brownian motion process, with respect to small changes of the boundary. Under broad assumptions on the nature of the boundary, including the Lipschitz condition (in a Hausdorff-type metric) on its time cross-sections, we obtain an analogue of the Borovkov and Novikov (2005) upper bound for the difference between boundary hitting probabilities for "close boundaries" in the univariate case. We also obtained upper bounds for the first boundary crossing time densities.Comment: 15 page

The impact of early stroke on identity: a discourse analytic study

This article examines the ways in which sufferers talk about early stroke and the effects this chronic condition has on identity. Traditional research into chronic illness has largely used medical, psychiatric or cognitive models. We adopt a social constructionist perspective and use a discourse analytic methodology to study data collected via focus group interaction. Analysis of the data collected shows that participants displayed sensitivity about having acquired a potentially ‘damaged’ sense of self by mitigating negative features of their experiences. Participants also attended to the issue of whether their accounts were persuasive or believable. Some carers were present in these discussions. As a consequence, participants who had suffered a stroke displayed sensitivity to the way that carers might respond to mitigation of the negative aspects of stroke

Student nurses' gender-based accounts of men in nursing

Stereotypes of nursing as a female profession and of male nurses as gay can limit male recruitment. This UK-based focus-group study examines whether student nurses reproduce or challenge such views. Using discourse analysis, discussion transcript segments dealing with male nurses’ gender or sexuality were examined for turn design, sequential organization, and procedural relevance. Results showed participants characterized such stereotypical constructions of male nurses as held only by other people. They themselves, however, used gender-based distinctions to problematic male nursing. These findings indicate nursing students would benefit from training which emphasizes the positioning of men and women within society
