Despite growing evidence that anxiety can be a significant problem in late-life, information regarding the use of mental health services by older adults for anxiety is lacking. The current research project consists of three studies focusing on this issue. The first study examines the rates of mental health service use among older adults with anxiety disorders and high levels of anxiety symptoms, as well as individual characteristics associated with this use. The second study examines various aspects of social support as correlates of anxiety disorders in older adults, and the role of social support as an enabling resource for mental health service use. Finally, the third study examines three important outcomes of service use among older adults: treatment satisfaction, perceived treatment effectiveness, and dropout. The data for these studies came from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2), a national population-based survey that includes 12,792 respondents aged 55+ years. This research found that older adults with significant anxiety were less likely to use services than those with mood disorders, and that indicators of need for services were the strongest predictors of use. Lower levels of functional social support were related to the presence of anxiety disorders among older adults, and lower levels of perceived emotional/informational support and positive social interactions predicted greater use of services for adults throughout the lifespan. Finally, older adults were generally satisfied with services, perceived them as helpful, and were likely to remain in treatment. Analyses indicated that individual characteristics likely play only a small role in these outcomes. In general, this project provides new and important information that can inform policy, clinical work, and future research regarding late-life anxiety.

<p>Bruxism is an oral parafunctional habit involving clenching and grinding of the teeth that occurs mainly unconsciously, diurnally and nocturnally. It is considered an important contributory factor in the aetiology of myofascial pain (MFP) and temporomandibular disorders (TMD). The aetiology of bruxism is considered to be multifactorial, involving physiological and psychological factors. The aim of this study was to examine the relationship between the subthreshold symptoms (subtle, prodromal, atypical and subclinical symptoms of which the severity precludes diagnosis as a disorder) of anxiety and bruxism in a sample of subjects using a spectrum model.</p>

The current research project has addressed the issue of the stress and anxiety experienced by Australian senior high school students as they prepare to undertake their final year examinations. Two studies were conducted. The first study looked at the feelings experienced by senior high school students, resources available to them to assist with exam preparation, resources actually accessed, and the strategies used to cope with examinations and associated feelings. Focus group interviews were conducted with 14 Year 11 and 13 Year 12 students from a public senior high school in Perth, Western Australia. Results indicated that students tend to most frequently report using avoidance strategies to cope with preparing and undertaking examinations, supporting previous research findings (e.g., Zeidner, 1996). The second study examined the effectiveness of a group based, cognitive behavioural program purposely designed to teach students strategies for coping specifically with test anxiety and also generalized anxiety symptoms. The program involved seven one-hour weekly sessions implemented with 31 Year 12 students who were undertaking their final year examinations. The program covered education about the nature and causes of stress and anxiety, relaxation training, cognitive restructuring, imaginal exposure and study skills training. The pre- and post-intervention scores on the TAI and RCMAS were analyzed using 2 (group) x 2 (gender) x 3 (symptom severity level) full factorial repeated measures ANOVAS. At pre-intervention, there were no significant differences between the treatment (N=31) and control (N=6), except for RCMAS Worry and Over Sensitivity, whereby the treatment group had a higher mean score, consistent with the greater ratio of female to male participants in the treatment group compared to the control group. At post intervention, the treatment group had reduced scores from preintervention levels for TAI Worry and Emotionality, RCMAS Total Anxiety, Physiological, Worry and Over Sensitivity and the Social Issues and Concentration subscales. In contrast, the post-intervention scores for the control group for these measures had increased from pre-intervention levels. However, there was no significant main effect for Group. Anecdotal program evaluation results from the treatment group students revealed that relaxation training was considered the most helpful aspect of the program. In contrast, at-home practice activities were considered the least helpful. A majority of participating students also reported that they believed the program would help them to manage stress and anxiety associated with examinations and other life stressors. Despite the lack of significant differences between the treatment and control groups in the current study, the pattern of results obtained generally followed that of previous research on the treatment of symptoms for test anxiety (e.g., Wessel & Mersch, 1994) and generalized anxiety (e.g., Kendall, 1994) employing a CBT approach. While the results of the current study may have been limited by the relatively small sample sizes of the treatment and control groups, the short- and longterm benefits of providing training in appropriate coping strategies for test anxiety, such as those involved in cognitive behavioural intervention, are further highlighted.

M.A. (Clinical Psychology) / Attention deficit hyperactivity disorder (ADHD) is a form of psychopathology characterised by difficulties with hyperactivity, attention and behavioural inhibition. Although ADHD has been historically considered a disorder specific to children, the contemporary consensus among researchers is that, in some cases, ADHD may persist into adulthood. Neurologically, ADHD is associated with deficits in the executive functions, located in the frontal lobe. Cortical arousal, which refers to the level of neuronal activity in the cerebral cortex and is measurable using electroencephalograph machinery (EEGs), is usually lower in the frontal lobes in those with ADHD when compared to individuals without the disorder. With regards to anxiety disorders, which are dysfunctional variations in the normal fear response, the aetiology of the pathologies in this category are multifaceted and complex. At the neurological level, however, there is a clear link between anxiety disorders and hypervigilance, which is characterised by high cortical arousal in the frontal lobes. Despite the fact that, at face value, it seems impossible for an increase and decrease in cortical arousal to occur simultaneously, ADHD is often diagnosed alongside anxiety disorders, and it is this anomaly which is the focus of this study. Electroencephalograph machinery (EEGs) are able to measure levels of cortical arousal using electrodes placed on the scalp. This research employs this equipment in order to elucidate on how cortical arousal manifests during a task that demands significant involvement from the frontal areas of the brain. A quasi-xperimental research design using non-parametric statistics (Mann-Whitney U Test) was used in order to compare the levels of cortical arousal between 4 groups of 5 research participants with either ADHD, an anxiety disorder, comorbid ADHD and anxiety and no discernible psychopathology. The significant results found in this study point to the fact that, in cases where ADHD and anxiety disorders occur comorbidly, there is a possibility that the anxiety component enables an individual to achieve more pronounced levels of attention, concentration and focus than normal participants and those with ADHD alone...

The current study examined whether variables that have been found to influence treatment outcome serve as mediators of a child and adolescent cognitive behavioral treatment (CBT) anxiety program at multiple time points throughout the intervention. The study also examined mediating variables measured at multiple time points during treatment to determine the time lags necessary for changes in the mediator variable to translate into changes on treatment gains. Participants were 168 youth (ages 6 to 16 years; 54% males) and their mothers who presented to the Child Anxiety and Phobia Program (CAPP) at Florida International University (FIU). Overall, results indicate that the mediators at multiple time points influenced youth anxiety in a fluctuating manner, such that a decrease in skills at one given session caused changes in youth anxiety at a later session. This dynamic between the mediator and outcome may be reflective of the process of therapeutic change and suggests that skills gained from session to session took time to exert their effect on youth anxiety. The methodology employed helps to elucidate how variables mediate treatment outcome in youth anxiety disorders.
