The Influence Of Model Features On Goodness-Of-Fit Indices: Choosing Indices To Evaluate Your Model, Andrea E. Berndt

Psychology Theses & Dissertations

Two studies were conducted to examine the performance of eight goodness-of-fit indices (i.e., the chi-square statistic, Comparative fit index, Critical N; Goodness-of-fit index, Normed fit index, Nonnormed fit index, Root mean square error of approximation, and Relative noncentrality index) used in structural equation applications. Study 1 consisted of (a) an empirical review in four journals (1986-1996) to determine the "typical" application, (b) a "recreation" of the goodness-of-fit indices from the published research, (c) a multiple regression analysis of the "recreated" indices to determine if values were predicted based on model and sample features, and (d) the development of a representative …

Analyzing The Effects Of Display Characteristics And Cognitive Variables On Performance Using Keystroke And Eye Movement Data, Orhan E. Beckman

Psychology Theses & Dissertations

Information about how operators use their eyes while interacting with visual displays is often an overlooked aspect of human-computer interaction. Such information is fundamental to assessing the quality of software interfaces and understanding the cognitive processes that underlie operator behavior. Other research evaluating information displays evolved from using reaction time and subjective data as dependent variables to using oculometric measures. In the current research conventional performance measures are coupled with oculometric measures to evaluate the influence display characteristics and cognitive variables have on performance.

Twelve subjects used a software program to complete a series of specified tasks. Subjects were asked …

Factor Analysis Of The Mmpi-A Content Scales: Item-Level And Scale-Level Analyses, Lisa Kay Mccarthy

Psychology Theses & Dissertations

This investigation identified and interpreted the overall factor structure of the MMPI-A content scales through the use of scale-level analyses, and examined the factor structure of each individual content scale through item-level analyses. The MMPI-A normative sample (805 males, 815 females) and a clinical sample (266 males, 92 females) were used in the analyses. Scale-level analyses yielded a two factor solution for the normative male and clinical groups and a one factor solution for the normative sample and normative female group. The factors were labeled General Maladjustment and Externalizing Tendencies. Item-level analyses provided one factor solutions for the majority of …

A Psychophysiological Assessment Of The Efficacy Of Event-Related Potentials And Electroencephalogram For Adaptive Task Allocation, Lawrence J. Prinzel Iii

Psychology Theses & Dissertations

The present study was designed to test the efficacy of using Electroencephalogram (EEG) and Event-Related Potentials (ERPs) for making task allocations decisions. Thirty-six participants were randomly assigned to an experimental, yoked, or control group condition. Under the experimental condition, a compensatory tracking task was switched between manual and automatic task modes based upon the participant's EEG. ERPs were also gathered to an auditory, oddball task. Participants in the yoked condition performed the same tasks under the exact sequence of task allocations that participants in the experimental group experienced. The control condition consisted of a random sequence of task allocations that …

Effects Of An Interview Guide On The Accuracy Of Ratings For Applicants With Disabilities, Catherine Quinn Greenwald Mergen

Psychology Theses & Dissertations

The problem of bias in the employment interview for applicants with disabilities was addressed with research to identify if a decision aid can increase the decision making accuracy of interviewers. A survey designed to allow participants to rate applicants with five disabilities for three jobs (with three essential functions listed for each job) was used to assess rating accuracy of two groups. Participants who received the decision aid in the form of a Guide to Interviewing People with Selected Disabilities were expected to have more rating accuracy than those participants without access to the Guide. Accuracy was assessed by comparing …

Men Who Batter: Personality Variables, Relationship Variables, And Treatment Outcome, Lisa M. Petrica

Psychology Theses & Dissertations

This study investigated the relationship between the personality characteristics of male batterers and treatment outcome. It also examined a pattern of communication found in violent couples where the male pursues the female and the female withdraws in an argument. The study also compared alcohol use with treatment outcome.

Twenty-one men who attended a group psychoeducational treatment program for batterers completed the Minnesota Multiphasic Personality Inventory (MMPI-2). The men were divided into three groups based on their scores: non-pathological (normal profile), narcissistic/antisocial (elevated psychopathic deviate scale), and severely disordered (elevations on several scales). Pre and post-test measures were completed: Dyadic Adjustment …

A Discovery-Oriented Process Study Of Enactment In Family Therapy: Development Of The Family Therapy Enactment Rating Scale, Elizabeth Ong-Mythuan Fong

Psychology Theses & Dissertations

With the effectiveness of psychotherapy now well-supported in both the individual and family literatures (Garfield & Bergin, 1994), we are entering an era where questions of how and why therapy works are of interest. More specifically, there has been support and encouragement by some researchers (Rice & Greenberg, 1984; Mahrer, 1988) for the use of discovery-oriented methodologies to explore clinical phenomena that have yet to be empirically validated. The following is a discovery-oriented study of enactment, a structural family therapy intervention. The theoretical goals of enactments, their relevance to clinical practice, as well as how they are actually implemented in …

The Relationship Between Ethnic Identity, Self-Esteem, Emotional Well-Being And Depression Among Lakota/Dakota Sioux Adolescents, Susan M. Pittenger

Psychology Theses & Dissertations

Despite conceptual support linking ethnic identity and psychological adjustment among Native Americans, empirical research examining this relationship remains limited. In light of recent developments in the area of ethnic identity research, including alternative conceptual models, improved methodologies, and more sophisticated measures, this study examined the relationship between ethnic identity, self-esteem, emotional well-being, and depression among Native American reservation youth.

The relationship between the predictor variables of American Indian ethnic identity, White-American identity and bicultural identity, and the criterion measures of self-esteem, emotional well-being, and depression were examined for 137 Lakota/Dakota Sioux reservation youth. Participants completed surveys including the Multigroup Ethnic …
