Working Alliance Between Interpretive And Noninterpretive Therapy Services For Deaf Individuals, Sherri Lee Spain

Walden Dissertations and Doctoral Studies

Deaf individuals typically have access to 2 types of therapeutic services: interpretive (with an interpreter) and noninterpretive (with a sign-fluent therapist). Previous research indicates that the presence of an interpreter may hinder development of working alliance and attachment. There is a lack of empirical evidence assessing the effect of working alliance and attachment based on whether or not therapy incorporates an interpreter. The working alliance theory and the attachment theory were the theoretical foundations for this study. This study examined the difference between the strength of working alliance and attachment to the therapist given the presence or absence of an …

Clinical Significance Of Response Shift In A Spine Interventional Clinical Trial, Robin Carlson

Walden Dissertations and Doctoral Studies

The effectiveness of treatments for degenerative spine conditions, where the primary symptom is back pain, is typically determined using patient-reported quality of life (QoL) measures. However, patients may adjust their internal standards when scoring QoL based on factors other than their health. This response shift phenomenon could confound the interpretation of study data and impact effectiveness conclusions. In the current study, response shift was examined using structural equation modeling (SEM) and previously collected clinical trial data comparing 2 minimally invasive medical devices in lumbar spinal stenosis patients through 1 year postintervention. In subject QoL results, reprioritization shift between 3 months …
