The Role Of Client Avoidance On Ptsd Recovery Throughout The Course Of Trauma Therapy, Chelsea Alyssa Gloth

Dissertations

The accumulation of randomized controlled trials (RCTs) for the treatment of posttraumatic stress disorder (PTSD) over the past few decades has contributed to the development of clinical treatment guidelines (Chambless & Ollendick, 2001; Forbes et al., 2010; Truax & Thomas, 2003). Two treatments that have gained substantial support are Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT). Although these treatments result in most participants losing their PTSD diagnosis and obtaining meaningful reductions in symptoms, some clients remain refractory to treatment. Researchers have worked to identify predictors of treatment outcome, but have given minimal attention to aspects of client avoidance as …

Improving Teacher Education In Missouri: Expanding Clinical Experiences To Broader Contextual Experiences, Julie Elizabeth Smith Sodey

Dissertations

Comprehensive improvement of America’s schools cannot occur without a dedicated, resourceful, and skillfully prepared pool of teachers. The growing emphasis on high-stakes testing and standards-based curriculum has resulted in unprecedented levels of scrutiny on schools, students, and especially teachers. Classroom teachers, once tasked primarily with educating students in core subject areas and rules of modern decorum and democracy, have now assumed a position of much greater consequence. Teachers often have to fulfill additional roles such as counselor, nurse, behavioral therapist, and social worker but are not adequately prepared for these responsibilities. This results in poorly supported students who are unable …
