Behavior Or Diagnosis? Effects Of Irritable Patient Behavior And Diagnostic Labels On Mental Illness Stigma, Nathan R. Huff
Behavior Or Diagnosis? Effects Of Irritable Patient Behavior And Diagnostic Labels On Mental Illness Stigma, Nathan R. Huff
Masters Theses
Although research demonstrates significant stigma towards individuals with mental illness, the relative importance of observed behavior and a psychiatric diagnosis in eliciting stigma remains poorly understood. Using video vignettes, three experiments (ns = 195, 749, and 791) examined the effect of irritable (vs. calm) behavior and the presence (vs. absence) of a psychiatric diagnosis (schizophrenia in Studies 1 and 2; schizophrenia and depression in Study 3) on attitudinal, emotional, and behavioral dimensions of stigma towards a fictitious emergency room patient seeking migraine treatment. In line with labeling theory, irritable behavior resulted in greater blameworthy attributions for behavior, greater fear and …
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Masters Theses
Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 mg/kg, IP), a psychostimulant …
Testosterone, Dominance, And Depression In Recently Married Couples, Gabriela I. Quiñones-Torres
Testosterone, Dominance, And Depression In Recently Married Couples, Gabriela I. Quiñones-Torres
Masters Theses
Dominance refers to the wide set of behaviors individuals engage in with the intention of achieving or maintaining social status. Considering the relevance of these behaviors in the dynamics of close relationships, this study examined relations among testosterone, dominance, and the emotional health of a total of 225 opposite sex newlywed couples. An original measure of dominance was developed that accounted for both positive and negative manifestations, as well as situational and dispositional qualities of these status-promoting behaviors. Structural equation analyses revealed that dominance behaviors predict depression for both wives and husbands, and that positive and negative aspects of dominance …
The Link Between Insecure Attachment And Depression: Two Potential Pathways, Cassandra C. Devito
The Link Between Insecure Attachment And Depression: Two Potential Pathways, Cassandra C. Devito
Masters Theses
A wealth of research demonstrates a strong link between insecure attachment and depressive symptoms. However, thus far no work has discerned different pathways to depression for each of the insecure subtypes: anxious and avoidant attachment. This work looks at the behaviors that couples engage in during a conflict interaction as a potential mediator for the attachment-depression relationship, with different behaviors mediating the link between anxious and avoidant attachment and depression. For anxiously attached individuals, it was predicted that lack of support and response from the partner (actual or perceived) would account for the relationship between their attachment and depressive symptoms. …
