Leadership’S Impact On Employee Work Motivation And Performance, Tonia Marilu Joseph-Armstrong Jan 2023

Leadership’S Impact On Employee Work Motivation And Performance, Tonia Marilu Joseph-Armstrong

Walden Dissertations and Doctoral Studies

AbstractLeadership is a major factor in terms of motivating employees, leading to enhanced performance. A study was conducted to examine the influence of supervisory leadership style on employee work motivation and job performance in organizations, specifically in a K-12 school setting. The main goal was to determine if there is a relationship between type of leadership demonstrated by school administrators and its impact on the teaching staff’s motivation and performance. Data for this quantitative study were gathered and analyzed from various public and private schools and included a sample of 100 participants. The predictor variable leadership was assessed using the …


Investigating The Quality Of Life For Children With Autism Spectrum Disorder Scale Using Rasch Methodology, Laura C. Chezan, Jin Liu, Ruiqin Gao, Erik Drasgow Jan 2023

Investigating The Quality Of Life For Children With Autism Spectrum Disorder Scale Using Rasch Methodology, Laura C. Chezan, Jin Liu, Ruiqin Gao, Erik Drasgow

Communication Disorders & Special Education Faculty Publications

Our purpose in this study was to provide additional psychometric evidence of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We used Rasch modeling to investigate the QOLASD-C functioning, the characteristics of the items comprising the scale, and the item functioning across subgroups of children with ASD based on gender and race/ethnicity. Results showed that QOLASD-C was unidimensional, met the local independence assumption, and measured quality of life (QOL). The items showed excellent fit to the model and good discriminating ability between low and high QOL. Most items showed a moderate difficulty level. No differential item …

Confidence Intervals For The Coefficient Alpha Difference From Two Independent Samples (Groups), Miguel Padilla Jan 2023

Confidence Intervals For The Coefficient Alpha Difference From Two Independent Samples (Groups), Miguel Padilla

Psychology Faculty Publications

Four different bootstrap methods for estimating confidence intervals (CIs) for a coefficient alpha difference from two independent samples (groups) were examined. These four CIs were compared to the most promising non-bootstrap CI alternatives in the literature. All CIs were assessed with a Monte Carlo simulation with conditions similar to previous research. The results indicate that there is a clear order in coverage performance of the CIs. The bootstrapped highest density interval had the best coverage performance across all simulation conditions. Yet, it was impacted by unequal sample sizes when one of the groups had the smallest sample size investigated of …


Efficiently Exploring The Causal Role Of Contextual Moderators In Behavioral Science, Cameron A. Hecht, Carol S. Dweck, Mary Murphy, Kathryn M. Kroeper, David S. Yeager Jan 2023

Efficiently Exploring The Causal Role Of Contextual Moderators In Behavioral Science, Cameron A. Hecht, Carol S. Dweck, Mary Murphy, Kathryn M. Kroeper, David S. Yeager

Psychology Faculty Publications

Behavioral science interventions have the potential to address longstanding policy problems, but their effects are typically heterogeneous across contexts (e.g., teachers, schools, and geographic regions). This contextual heterogeneity is poorly understood, however, which reduces the field's impact and its understanding of mechanisms. Here, we present an efficient way to interrogate heterogeneity and address these gaps in knowledge. This method a) presents scenarios that vividly represent different moderating contexts, b) measures a short-term behavioral outcome (e.g., an academic choice) that is known to relate to typical intervention outcomes (e.g., academic achievement), and c) assesses the causal effect of the moderating context …


Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel Jan 2023

Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel

Theses and Dissertations (Comprehensive)

There are myriad methods offered in the “self-help industry” and on social media promising to improve happiness. Some messages are evidence-based, often drawn from positive psychology research, and suggest actions requiring time and effort, while other messages may offer feel-good platitudes that are devoid of meaningful guidance; we label this latter type of content “inspirational bullshit.” Across two manuscripts, we investigate the predictors of liking different kinds of positive self-help content, from meaningless randomly-generated phrases to vacuous positivity to evidence-based advice. In the first manuscript, across three studies, bullshit receptivity (a tendency to judge pseudo-profound statements as profound) and people’s …
