The Role Of Alexithymia And Affective Lability In Disordered Eating Behaviors, Anna Marie Lilia Ortiz
The Role Of Alexithymia And Affective Lability In Disordered Eating Behaviors, Anna Marie Lilia Ortiz
Theses and Dissertations--Psychology
Affective distress may influence eating disorder behaviors in multiple ways. Affective lability refers to the tendency to experience frequent and striking fluctuations in mood. There is considerable evidence that it predicts eating disorder symptoms. Further, alexithymia is characterized by difficulties identifying and describing feelings and an externally oriented thinking style. Alexithymia has also been implicated in the development and maintenance of eating disorders. To date, these risk factors have been studied separately. Given the evidence that both alexithymia and affective lability are affective components associated with eating disordered behaviors, it may be important to examine possible relationships among alexithymia, affective …
Modeling Daily Posttraumatic Stress Symptoms And Mental Contamination Experiences Among Survivors Of Sexual Trauma, C. Alex Brake
Modeling Daily Posttraumatic Stress Symptoms And Mental Contamination Experiences Among Survivors Of Sexual Trauma, C. Alex Brake
Theses and Dissertations--Psychology
Mental contamination (i.e., feelings of dirtiness in the absence of contact with a contaminant) is a potentially important yet understudied factor in posttraumatic psychopathology, particularly for survivors of sexual trauma. Mental contamination has been linked to PTSD symptom severity, negative affect, and coping cross-sectionally and in lab-based paradigms, but research has yet to assess these relationships in ecological contexts. The present study extends previous cross-sectional findings by modelling relationships between mental contamination and posttraumatic psychopathology, emotions, and coping both within-day and from one day to the next. Forty-two female sexual trauma survivors completed twice-daily assessments of mental contamination, PTSD symptoms, …
Loss Aversion In Cocaine Users: Influence Of Risk And Commodity Type, Justin Charles Strickland
Loss Aversion In Cocaine Users: Influence Of Risk And Commodity Type, Justin Charles Strickland
Theses and Dissertations--Psychology
Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in healthy populations, little research exists in individuals with substance use disorders. The purpose of this study was to comprehensively evaluate loss aversion in cocaine users. Participants completed measures designed to assess loss aversion for drug and non-drug commodities under varying risk conditions. Cocaine demand was determined using a cocaine purchase task. Cocaine users showed a loss aversion score that was consistent across commodity and risk conditions. Compared to …
Eating Disorder Onset In Young Girls: A Longitudinal Trajectory Analysis, Carolyn M. Pearson
Eating Disorder Onset In Young Girls: A Longitudinal Trajectory Analysis, Carolyn M. Pearson
Theses and Dissertations--Psychology
To investigate whether there are different patterns of development for binge eating and purging behavior among pre-adolescent and early adolescent girls, I conducted trajectory analyses of those behaviors in 938 girls across eight waves of data from the spring of 5th grade (the last year of elementary school) through the spring of 9th grade (the first year of high school). Analyses revealed four separate developmental trajectories for binge eating behavior (labeled none, increasing, decreasing, and high steady) and three separate developmental trajectories for purging behavior (labeled none, dabble, and increasing). Fifth grade scores on risk factors that were …
