The Association of Childhood Trauma, Eating Disorder Symptoms and General Psychopathology in Individuals with Eating Disorders

Klopfer, Kristina Monika 31 May 2011 (has links)
The purpose of this study was to investigate the influence of childhood sexual, physical and emotional abuse and childhood emotional and physical neglect on eating disorder symptoms and general psychopathology. This study utilized a cross-sectional research design incorporating a combination of self-report measures and clinical interviews. Seventy participants were recruited from two eating disorder treatment centres. A series of univariate tests revealed no significant differences between individuals who reported a mild level of trauma and those who reported a severe level of trauma on all clinical measures. Logistic regression analyses revealed associations between impulsivity and childhood physical abuse and between psychiatric comorbidity and childhood physical neglect. Few associations were found and the observed effect sizes were generally small suggesting that the null findings were not due to inadequate power. It may be that the study sample differed from those used in previous investigations in which significant associations have been documented.

Social Anxiety Disorder: Behavioural Characteristics Associated with the Cortisol Stress Response

Vaccarino, Oriana 10 December 2013 (has links)
The present study evaluated the cortisol stress response and its relationship to several behavioural measures in SAD participants. It is hypothesized that SAD participants will show an exaggerated cortisol response to the Trier Social Stress Test (TSST) and differing positive and negative affects compared to controls, as well as correlations between the two measures. SAD (n=12) and controls (n=12) underwent the TSST. Serial plasma cortisol samples were taken and self-report measures were completed. The plasma cortisol levels were numerically higher in SAD at all time points compared to controls but the difference was not statistically significant. Cortisol response correlated inversely with childhood emotional abuse (p=0.01) and directly with positive affect (p=0.02) in SAD participants. Furthermore, SAD participants reported greater negative affect (prior to and after TSST) and more frequent emotional abuse than controls. SAD is associated with changes in HPA axis activity and affective states that differ from controls.

Metamemory Processes in Persons with Schizophrenia

McAnanama, Edward 08 August 2013 (has links)
Memory impairment in Schizophrenia (SCZ) is robust and associated with poor functional outcome. However, these correlations are only moderate in magnitude, leading some researchers to propose that metamemory deficits may also underpin poor memory performance and related functional deficits in this population. The purpose of this dissertation was to assess various aspects of metamemory performance among persons with SCZ. The studies are organized along a temporal continuum of metamemory processes, operating from retrieval to output. Study 1 evaluated whether persons with SCZ control retrieval by re-instating the processing mode employed at encoding (i.e., source-constrained retrieval). Participants studied words under deep or shallow conditions and then completed two recognition tests – a standard test followed by the memory-for-foils test (i.e., foils from the first test become targets on the second test). Only HCs in the deep encoding condition exhibited superior memory for foils, suggesting diminished source-constrained retrieval among persons with SCZ. In study 2, criterion setting and adjusting was investigated by altering the relative distinctiveness between lures and targets on two separate recognition tests. Persons with SCZ set a stricter criterion but adjusted it appropriately in response to lure distinctiveness (i.e., difficulty). In study 3, the strategic regulation of response granularity (i.e., from fine [e.g., 1:20 pm] to coarse [e.g. afternoon] was investigated by manipulating monetary incentives and penalties. Results show that persons with SCZ are overconfident in their memories and impaired in modulating granularity. Collectively these studies suggest a pattern of both intact and deficient metamemory skills characterize persons with SCZ. Possible underlying mechanisms and functional implications of this pattern are discussed.

Neuroanatomical Correlates of Depressive Symptoms Following Acute Ischemic Stroke

Francis, Philip 24 August 2011 (has links)
This study investigated the hypothesis that severity of depressive symptoms following acute ischemic stroke is associated with degree of tissue infarction and severity of white matter changes (WMCs). It employed a novel quantitative region-based approach considering both infarction and WMCs. Of 54 ischemic stroke patients recruited, 50 (72.3 ± 12.8 years, 52.0% male) had useable CT scans. The typical patient was recruited within 3 weeks of their stroke (19.7 ± 31.0 days), exhibited minor cognitive impairment (MMSE score 25.8 ± 4.6), and had mild to moderate stroke severity (NIHSS score 6.5 ± 5.4). 28.0% of patients screened positive for clinical depression with a CES-D score ≥16. While neither degree of infarction nor severity of WMCs (ARWMC score) in the 12 brain regions correlated with depressive symptoms (CES-D score), stroke severity was a significant predictor of depressive symptoms. This stressor, related to physical disability, was a predominant predictor over lesion characteristics.

A Cost of Illness Study of Generalized Anxiety DisorderI in Canada

Bereza, Basil G. 14 December 2010 (has links)
Background: Economic evaluations of generalized anxiety disorder (GAD) have been limited to ≤18 months. A decision model was developed; quantifying the lifetime cost-of-illness (COI) of GAD. Methods: An incidence-based Markov-model was developed using TreeAge® software, reflecting 9 health-states (HS): physician-assessed patients (3HS), maintenance therapies(4HS), discontinuation(1HS) and death(1HS). Onset probability (ages 18-80) determined model entry. Canadian Psychiatric Association (CPA) guidelines determined pharmaco-therapy, with revisions/validation by an expert panel. Response, remission based on pooled-analysis of CPA-cited evidence. Remaining clinical rates, absenteeism and hospitalization retrieved from literature. Direct (clinician, pharmacotherapy, hospitalization) and indirect costs (wage rate) retrieved from government publications. Results discounted at 5%. Results: The mean COI was 2008 Canadian $31,213(SD=$9,100)/patient; 96% attributed to absenteeism. Mean age=31years, discontinued treatment=85% by 2nd year, treatment discontinuation duration, 14(SD=9) years. CONCLUSION: GAD is a costly disease with a lifetime COI<$32k/patient; absenteeism exerts a significant impact. Limited prospective data contributes to uncertainty of estimate.
