Development Of An Explainability Scale To Evaluate Explainable Artificial Intelligence (Xai) Methods, Stephen Mccarthy

Dissertations

Explainable Artificial Intelligence (XAI) is an area of research that develops methods and techniques to make the results of artificial intelligence understood by humans. In recent years, there has been an increased demand for XAI methods to be developed due to model architectures getting more complicated and government regulations requiring transparency in machine learning models. With this increased demand has come an increased need for instruments to evaluate XAI methods. However, there are few, if none, valid and reliable instruments that take into account human opinion and cover all aspects of explainability. Therefore, this study developed an objective, human-centred questionnaire …

Can Ratings Of Item Location Enhance Statistical Item Parameter Estimation? Extending The Feasibility Of Unfolding Irt Models, Michael Mckenna

Dissertations

Research and development of modern psychometric methods such as item response theory have drastically changed the way we understand and carry out the measurement of psychological constructs. Despite this, there has been relatively little adoption by psychological researchers to incorporate these methods into their research. While multiple explanations are surely valid, one oft stated reason is the large sample size requirements of these methods. The sample size requirements of item response theory are needed so that effective estimation of item parameters can be carried out. In an attempt to make these modern measurement methods more accessible and feasible to psychological …

Measurement Of Defusion: Further Validation Of The Drexel Defusion Scale, Christopher A. Briggs

Dissertations

Acceptance and Commitment Therapy (ACT) seeks to develop psychological flexibility through the engagement of the six interrelated processes. Four processes employ mindfulness and acceptance strategies and consist of acceptance, defusion, present moment awareness, and the contextualized self. Two other processes, values and committed action, are grouped with present moment awareness and the contextualized self and are termed behavior change strategies. One issue encountered by contemporary behavioral approaches in general, and ACT in particular, is the measurement of the proposed processes. Measurement is complicated by the functional nature of some of the repertoires described making the development of instruments for assessment …

Explicit, Implicit, And Behavioral Stigmatization Of Mental Illness, Jessica S. James

Dissertations

Mental health concern is a public health concern that continues to be stigmatized. While the dual process model has been applied to other areas of social cognition (e.g., racism), this framework has not previously been frequently used to examine the stigmatization of mental illness. The current study sought to examine the stigmatization of mental illness within a dual process model to determine the relationship between explicit and implicit stigmatizing attitudes and behaviors. A total of 104 undergraduate students from the University of Southern Mississippi participated in this study. Participants completed multiple implicit and explicit measures of stigmatizing attitudes and behavioral …

Emotional Intelligence And Leader Development: Measuring Trait Emotional Intelligence Scores Of Mid- Career Commissioned U.S. Army Officers, Stephan Lorentz Walters

Dissertations

The United States Army is preparing for the ambiguous and consistently changing realities of the modern world by developing leaders who are adaptive, mentally agile, and open to change. However, without instruments or tools that purposefully measure adaptability within each individual leader, it is challenging to determine the U.S. Army’s effectiveness at the strategic goal to develop adaptive and self-aware leaders.

The dependent variables of interest are the trait emotional intelligence scores of commissioned U.S. Army leaders who have at least 10 years of military experience. This quantitative survey based study samples (N = 28) mid-career U.S. Army Majors using …

Validation Of The Young Adult Relational Aggression Scale, Caitlin M. Clark

Dissertations

Relational aggression has been associated with a host of negative correlates in previous studies of children, adolescents, and emerging adults. Further research is necessary for the purposes of identifying prevention and intervention strategies; however, research on relational aggression among emerging adults has been complicated by the lack of available psychometrically sound measures, particularly those that capture the proactive and reactive functions of relational aggression. The present study extended previous efforts to develop a new self-report measure of relational aggression for emerging adults called the Young Adult Relational Aggression Scale (YARAS). A confirmatory factor analysis (CFA) was performed using a sample …

Healthcare Use Self-Efficacy In Adults Who Are Homeless, Jared Ian Israel

Dissertations

The physical and mental health care needs of homeless adults are extensive. However, these needs regularly go unmet. Healthcare use behavior is complex and involves a range of obstacles. As such, self-efficacy, an individual’s belief in his or her ability to perform a given behavior, appears to be a relevant factor in healthcare use. While current theory supports this notion and research has confirmed the role of self-efficacy in health behavior generally, a validated measure of healthcare use self-efficacy has not previously existed. The aim of this study was to develop and validate the Healthcare Use Self-Efficacy List (HUSEL) in …

Development And Validation Of A Measure Of Perceived Life Significance, Rachel Hibberd

Dissertations

Theoretical and empirical approaches to the study of meaning in bereavement suggest a distinction between meaning as sense-making, or the integration of the loss into a coherent and positive set of beliefs about world and self, and meaning as life significance, or the perception that some aspect of one's life experience “matters” in the wake of loss. Although several authors have pointed to the importance of life significance in grief recovery, currently no psychometrically valid measure exists. The present study examined the reliability and validity of a new measure: the Perceived Life Significance Scale (PLSS). The PLSS total score, as …
