Treatment Outcome From Cognitive Processing Therapy Examined Three Ways, Sophie Haven
Treatment Outcome From Cognitive Processing Therapy Examined Three Ways, Sophie Haven
Dissertations
Cognitive Processing Therapy (CPT), a Cognitive Behavioral Therapy for treating Post Traumatic Stress Disorder (PTSD), is an evidence-based treatment that has been demonstrated to be effective in treating PTSD. Nonetheless, CPT can have a high rate of treatment non-completion. Attrition from therapy has been operationally defined using multiple contrasting methods. Understanding attrition using a definition with the most clinical utility is essential to improving outcomes from efficacious treatments. Two clinically relevant definitions for attrition, session attendance and symptom improvement, are critical to understanding attrition. Combining information from both definitions, to create four separate groups, will provide more accurate information about …
Neurobiological Mechanisms Of Cognitive Processing Therapy For Post-Traumatic Stress Disorder: A Brain Network Approach, Tessa Vuper
Dissertations
Psychotherapy research is increasingly targeting both psychological and neurobiological mechanisms of therapeutic change. This trend is evident in and applicable to post-traumatic stress disorder (PTSD) treatment research given the high nonresponse rate of individuals with PTSD who undergo cognitive-behavioral therapy (CBT). A review of the literature investigating neurobiological mechanisms of CBT in PTSD reveals inconsistent results that fail to fully support dual process or learning models of CBT effects in the brain. However, network-based models of psychopathology provide a new framework from which to understand both mental disorder symptoms and therapeutic mechanisms. The current study investigated a) whether brain networks …
Ptsd Symptom Interaction Among Victims Of Interpersonal Violence: A Network Analysis, Robert Graziano
Ptsd Symptom Interaction Among Victims Of Interpersonal Violence: A Network Analysis, Robert Graziano
Dissertations
Along with numerous combinations of symptoms, posttraumatic stress disorder (PTSD) is linked to high dropout and non-response rates in treatment. Poor treatment response may be due to an inaccurate conceptualization of PTSD. One newer approach to the conceptualization of psychopathology is network theory. Network theory posits that symptoms both directly and indirectly reinforce each other, with connections between symptoms varying in strength. Previous studies of network theory and PTSD have found intrusive symptoms to be highly central, but have not included samples of individuals traumatized by interpersonal violence. Because trauma type has been shown to predict symptom presentations, this represents …
Examining The Gender- And Sexuality-Related Cognitive “Stuck Points” Of Men And Women With Experiences Of Adult Sexual Assault: Implications For Cognitive Processing Therapy, Marin Beagley
Dissertations
Cognitive Processing Therapy (CPT) is considered a gold-standard psychotherapy protocol for the treatment of posttraumatic stress symptoms secondary to a variety of traumatic events. Despite its demonstrated efficacy, there is research to suggest CPT may not be as effective in reducing PTSD symptoms for men with an adult sexual assault trauma as it is for their female counterparts. The purpose of the present study was to determine whether CPT treatment outcome discrepancies may be attributable to gender differences in posttraumatic cognitions, or “stuck points.” As the act of sexual victimization is incongruent with socially prescribed masculine gender norms, it was …
Understanding Comorbid Depression In The Context Of Ptsd Through Underlying Dimensions, Melissa Turkel
Understanding Comorbid Depression In The Context Of Ptsd Through Underlying Dimensions, Melissa Turkel
Dissertations
Depression co-occurs with Posttraumatic Stress Disorder at a high rate, resulting in numerous complications for pathology and treatment. More research is needed regarding variables that may explain this common comorbidity. One possible variable is that of underlying dimensions, latent factors that give rise to these manifestations of psychopathology. This study explored potential underlying mechanisms of comorbid PTSD and depression, including negative affect, rumination, emotion dysregulation, neuroticism, and behavioral inhibition. While previous studies have investigated these dimensions individually, there is a dearth of research that simultaneously investigates multiple dimensions or determines the relative contributions of underlying dimensions to psychopathology. Thus, the …
Clinician Bias In The Diagnosis Of Posttraumatic Stress Disorder: How Clinician Characteristics And Training May Relate To Diagnosis, Renee Boeck
Dissertations
As our understanding of PTSD has advanced, changing demographics in the United States over the past few decades have led to a growing awareness of the mental health needs of an increasingly diverse and multicultural population. Research on ethnoracial differences in PTSD has had mixed results and additional research exploring possible contributing factors is needed to better explain observed differences. This study explored the presence of and contributing factors to clinician bias in the diagnoses of PTSD based on race and context. It examined whether clinicians were more likely to diagnose PTSD in a Black or White man due to …

Cognitive Behavioral Therapy Is Associated With Enhanced Cognitive Control Network Activity In Major Depression And Posttraumatic Stress Disorder, Zhen Yang, Desmond Oathes, Kristin Linn, Steven Bruce, Theodore Satterthwaite, Philip Cook, Emma Satchell, Haochang Shou, Yvette Sheline
Psychology Faculty Works
BACKGROUND: Both major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are characterized by depressive symptoms, abnormalities in brain regions important for cognitive control, and response to cognitive behavioral therapy (CBT). However, whether a common neural mechanism underlies CBT response across diagnoses is unknown. METHODS: Brain activity during a cognitive control task was measured using functional magnetic resonance imaging in 104 participants: 28 patients with MDD, 53 patients with PTSD, and 23 healthy control subjects; depression and anxiety symptoms were determined on the same day. A patient subset (n = 31) entered manualized CBT and, along with controls (n = …
Fidelity To The Cognitive Processing Therapy Protocol: Further Evaluation Of Critical Elements, Courtney Chappuis Farmer
Fidelity To The Cognitive Processing Therapy Protocol: Further Evaluation Of Critical Elements, Courtney Chappuis Farmer
Dissertations
Despite advancements in the field of trauma-focused treatment, a close examination of the literature reveals three concerns. First, a significant number of RCT participants either do not respond to treatment or drop out prematurely. Second, despite significant dissemination of evidence-based interventions, fidelity to those interventions beyond trainings is not well understood. And finally, the effectiveness of trauma-focused interventions in the “real-world” community setting remains unclear. Literature suggests that identification of key treatment components could help to address these three concerns. This study focused on one evidence-based treatment in particular, Cognitive Processing Therapy (CPT), and aimed to extend the current literature …
The Psychological Flexibility Model And Ptsd Intrusion Symptoms, Kaylin Jones
The Psychological Flexibility Model And Ptsd Intrusion Symptoms, Kaylin Jones
Dissertations
The psychological flexibility model offers a lens through which to view the development and maintenance of PTSD symptoms. The model consists of six behavioral processes, including cognitive fusion, experiential avoidance, and lack of contact with the present moment, which are said to interact with each other to either resolve or maintain symptoms of PTSD. The mediation models proposed within the psychological flexibility model have yet to be examined within any sample. This study examined the relationships between cognitive fusion, experiential avoidance, lack of contact with the present moment, and PTSD intrusion symptoms within a sample of trauma-exposed adults experiencing symptoms …
Cultural Conceptualizations Of The Trauma Response: The Role Of Locus Of Control, Religiosity, And Religious Coping, Yu-Feng Emily Hu
Cultural Conceptualizations Of The Trauma Response: The Role Of Locus Of Control, Religiosity, And Religious Coping, Yu-Feng Emily Hu
Dissertations
Posttraumatic stress disorder (PTSD) is a relatively recent diagnosis that results in significant personal and societal costs. Given the diversity of American mental health consumers, a more thorough understanding of PTSD and its relation to cultural factors may have important implications for treatment implementation and refinement. Cultural factors such as locus of control, religiosity, and religious coping have been frequently overlooked in trauma research, yet show a clear link to PTSD risk and symptomatology. This study examined these cultural factors in more detail with relation to race and trauma type and their combined influence on PTSD symptomatology. A national sample …
Neural Correlates Of Rumination In Posttraumatic Stress Disorder Before And After Cognitive Processing Therapy, Katherine Ruth Buchholz
Neural Correlates Of Rumination In Posttraumatic Stress Disorder Before And After Cognitive Processing Therapy, Katherine Ruth Buchholz
Dissertations
The utilization of functional magnetic resonance imaging (fMRI) techniques to examine biomarkers and neural activity patterns related to posttraumatic stress disorder (PTSD) has provided a way to investigate mechanisms that underlie the development, maintenance, and recovery from PTSD. Studying the neural correlates of individual differences related to transdiagnostic factors has the potential to provide clinically relevant information beyond that of diagnostic categories. Rumination is one such factor. Rumination, defined as repetitive, negative, self-focused thinking is considered to be a transdiagnostic factor that is associated with depression, anxiety, and PTSD. In individuals with PTSD, rumination serves as a cognitive avoidance factor …
Coping Styles Among Individuals With Severe Mental Illness And Comorbid Ptsd, Shannon Ashley Mcneill
Coping Styles Among Individuals With Severe Mental Illness And Comorbid Ptsd, Shannon Ashley Mcneill
Dissertations
There is little known about the mechanisms by which persons with SMI cope with their stress, and virtually no research is available on the influence of comorbid PTSD (SMI-PTSD) on coping within the SMI population. The current study examined coping strategies utilized by individuals with SMI versus those with SMI-PTSD, while also investigating the role of PTSD symptom severity, overall psychological distress, and substance use on coping strategy usage. Participants included adults (N = 90) recruited through a metropolitan community mental health center, all describing current symptoms of an SMI, 48 of whom met criteria for SMI-PTSD. Results of this …
The Relationship Between Posttraumatic Cognitions And Social Support In The Severity Of Ptsd Symptoms, Ellen Margaret Koucky
The Relationship Between Posttraumatic Cognitions And Social Support In The Severity Of Ptsd Symptoms, Ellen Margaret Koucky
Dissertations
Posttraumatic cognitions (PC), perceived social support (PSS), and received social support (RSS) contribute to the development of posttraumatic stress disorder (PTSD), but little is known about the way these variables may influence each other in this process. The current study tested the association between PSS and RSS and compared levels of these support types in PTSD-positive versus PTSD-negative subjects. An SEM model investigating the role of PC, PSS, and RSS in predicting PTSD symptom severity was also tested. Results indicate a significant difference in the strength of the association between support types based on diagnostic status and lower levels of …
Decision-Making Following Sexual Assault: Reporting Decisions And Exposure To The Criminal Justice System, Ryan Michael Walsh
Decision-Making Following Sexual Assault: Reporting Decisions And Exposure To The Criminal Justice System, Ryan Michael Walsh
Dissertations
Violent crimes represent significant costs to society and survivors; costs which include mental health conditions which may emerge afterward. Victims of sexual assault are at particularly heightened risk for developing posttraumatic stress disorder (PTSD) (Breslau, Davis, Andreski, & Peterson, 1991). Although Crime Victims’ Compensation (CVC) is available to assist with healthcare costs for some individuals who report the event to police (NACVCB, 2009), many crimes are not reported. Theories of crime-reporting behavior suggest that victims decide whether to report crimes to police through the use of a “cost-benefit analysis” (Gottfredson & Gottfredson, 1988, p. 25). Little research, however, has been …
Maternal Posttraumatic Stress Disorder, Parenting, Family Functioning, And Child Outcome, Desiree Alana Sutherland
Maternal Posttraumatic Stress Disorder, Parenting, Family Functioning, And Child Outcome, Desiree Alana Sutherland
Dissertations
Although a good deal of research has been conducted examining the effects of parental psychopathology of various types (i.e. maternal and paternal depression and schizophrenia, paternal PTSD), very few studies have investigated the influence of maternal PTSD on mothers’ parenting and their children’s behavioral and psychological functioning. This paucity of research is in spite of the fact that women exhibit higher lifetime PTSD prevalence rates than men. The current study examined the influence of maternal PTSD and trauma on mothers’ parenting, family functioning, and children’s psychological well-being in a sample of 125 mothers and 34 mother-child dyads. Mothers provided self-report …
Emotional Response Patterns And Emotional Numbing In Adult Female Victims Of Sexual Assault With Ptsd, Tristan A. Robinson
Emotional Response Patterns And Emotional Numbing In Adult Female Victims Of Sexual Assault With Ptsd, Tristan A. Robinson
Dissertations
DSM symptoms of emotional numbing appear to have a major impact on the course and outcome of posttraumatic stress disorder (PTSD), yet the construct definition of emotional numbing itself has not been clearly established. Two opposing conceptualizations of this construct have been proposed in the traumatic stress literature. One holds numbing to be a form of non-effortful emotional avoidance, akin to dissociation, that results in diminished responsiveness to emotional stimuli in general (Foa, Zinbarg, & Rothbaum, 1992; Foa & Hearst-Ikeda, 1996). The other suggests that numbing entails a deficit in responsiveness to positive emotional stimuli but not to negative emotional …
