Role Of The Default-Mode Network During Narrative Integration In Major Depressive Disorder, Darren Ri-Sheng Liang

Electronic Thesis and Dissertation Repository

How brain activity is synchronized across individuals during narrative comprehension has previously been characterized by functional magnetic resonance imaging (fMRI) in healthy and patient populations. To our knowledge, there has been limited investigation as to how it is affected by major depressive disorder (MDD). We addressed this issue with fMRI through examination of inter-subject synchronization in the default mode network (DMN), brain structures which have previously been implicated in MDD pathology. Twenty-two patients with MDD and 20 matched control participants listened to Intact versus Scrambled versions of an auditory narrative; these experimental conditions differed in the degree of temporal integration …

Changes In Depression And Positive Mental Health Among Youth In A Healthy Relationships Program, Natalia Lapshina, Claire Crooks, Amanda Kerry

Journal Articles

Mental health promotion programming in schools and community settings is an important part of a comprehensive mental health strategy. The goal of this study was to identify and explore meaningful classes of youth based on their pre- and post-intervention depression symptoms scores with 722 youth involved in a 15-week healthy relationships and mental health promotion program. We utilized latent class growth analysis to identify depression class trajectories, controlling for group clustering effects. A three-class solution identified high decreasing, moderate stable, and low stable trajectories. Gender, age, and reported experience of bullying victimization predicted trajectory class membership. The low stable class …

An Analysis Of The Relationship Between Humor Styles And Depression, Marisa L. Kfrerer

Electronic Thesis and Dissertation Repository

The present study examined the relationship between humor styles and depression using two methods of examination: (1) the mean humor style differences between individuals who reported that they had been diagnosed with depression versus those who did not report being depressed; and (2) a short scale assessing depressed affect. Participants were 878 adult Australians. With respect to mean differences, depressed individuals were found to use self-defeating humor more, and self-enhancing humor less than non-depressed adults. When the depressed affect scale score was analyzed, negative correlations were found between depressed affect and both positive styles of humor, affiliative and self-enhancing. Additionally, …

MacDonald Franklin OSI Research Centre

Background

Past research on the association between insomnia and suicidal ideation (SI) has produced mixed findings. The current study explored the relationship between insomnia, SI, and past-year mental health status among a large Canadian Forces (CF) sample.

Method

Data was obtained from the 2013 Canadian Forces Mental Health Survey (CFMHS), and included a large representative sample of Canadian Regular Forces personnel (N = 6700). A series of univariate logistic regressions were conducted to test individual associations between past-year mental health status, insomnia, and potential confounds and SI. Mental health status included three groups: 0, 1, or two or more …
