The current study was designed to examine whether levels of trait narcissism and peer attachment anxiety in adolescence predict satisfaction with the decision to hide publicly viewable likes on Instagram and authenticity in Instagram use since the implementation of this decision. Participants (21.7% male, 78.3% female, M = 1.78, SD = .41) first completed The Narcissistic Personality Inventory for Children, then The Peers Attachment Scale, followed by scales I created to measure satisfaction with, authenticity of, and ...


Content Validity Evaluation Of An Unnamed National Professional Organization Certification Exam, Sean Tate Apr 2020

Content Validity Evaluation Of An Unnamed National Professional Organization Certification Exam, Sean Tate

Masters Theses & Specialist Projects

Department of Psychological Sciences Western Kentucky University There are three validation strategies utilized for evaluating tests, content validity, construct validity, and criterion-related validity. Each of these methods serves a different and unique purpose when it comes to the validation of tests. Content validity pertains to whether the content measured by the test is representative of the content domain. Verifying content validity is a multi-step process involving conducting a job analysis, identifying content domains, creating test specifications, creating test items, and then conducting analyses to identify whether or not the test items are representative and in accordance with the test specifications ...


Norming The Peterson Assertiveness Questionnaire, Haley Peterson, Carrie Lewis Miller Jan 2020

Norming The Peterson Assertiveness Questionnaire, Haley Peterson, Carrie Lewis Miller

IT Solutions Publications

An assertiveness measure was developed based on the Mind Tools framework for fostering assertive behaviour (‘How to be Assertive,’ n.d.). Previous research supports the elements within the Mind Tools framework, but none has been conducted on Mind Tools specifically. Therefore, the purpose of this study is to first verify the construct, and then test the questionnaire based on that framework for its psychometric properties as well as norm the measure. Questions developed ranged from passive in nature to aggressive with varying informants. The construct was validated through a Principle Components Analysis. The measure was normed using pilot testing and ...

#Gaslighting, Karissa Moody

Counseling and Family Therapy Scholarship Review

As the utilization of social media continues to integrate itself into domains of culture, livelihood, and worldviews, the following exposition aims to introduce how such integration may pose as a new realm of gaslighting that has yet to be discussed. The progressive conceptualization of gaslighting as a form of manipulation will aid in providing readers with an understanding of this idea through a systemic lens by first, explaining underlying reasons for manipulation as an all-inclusive concept. The value of explication will serve in identifying plausible reasons of manipulation which pertain to the concept of gaslighting within social media. Within this ...


The Validation Of The Multicultural Supervision Scale, Varunee Faii Sangganjanavanich, Yue Dang, Xin Liang Nov 2019

The Validation Of The Multicultural Supervision Scale, Varunee Faii Sangganjanavanich, Yue Dang, Xin Liang

The Journal of Counselor Preparation and Supervision

The Multicultural Supervision Scale (MSS) is a self-reported instrument aimed at measuring supervisors’ multicultural supervision competencies. A total of 308 individuals completed the present study for the purpose of validating the MSS with the consideration of the influence of social desirability. Results from a confirmatory factor analysis confirmed the three-factor structure of the MSS including Supervisory Skills, Supervisors’ Attitudes and Beliefs, and Stereotypes Toward Diverse Populations. Statistical evidence suggested that the MSS, which consists of 21 self-reported items, demonstrated a moderate level of internal consistency and validity of its construct. Directions for future research and implications to clinical supervision and ...


Crowdsourcing Job Satisfaction Data: Examining The Construct Validity Of Glassdoor.Com Ratings, Richard N. Landers, Robert C. Brusso, Elena M. Auer Nov 2019

Crowdsourcing Job Satisfaction Data: Examining The Construct Validity Of Glassdoor.Com Ratings, Richard N. Landers, Robert C. Brusso, Elena M. Auer

Personnel Assessment and Decisions

Researchers, practitioners, and job seekers now routinely use crowdsourced data about organizations for both decision-making and research purposes. Despite the popularity of such websites, empirical evidence regarding their validity is generally absent. In this study, we tackled this problem by combining two curated datasets: (a) the results of the 2017 Federal Employee Viewpoint Survey (FEVS), which contains facet-level job satisfaction ratings from 407,789 US federal employees, and which we aggregated to the agency level, and (b) current overall and facet ratings of job satisfaction of the federal agencies contained within FEVS from Glassdoor.com as scraped from the Glassdoor ...

Martin Stephens, PhD

The Evidence-based Toxicology Collaboration (EBTC) was established recently to translate evidence-based approaches from medicine and health care to toxicology in an organized and sustained effort. The EBTC held a workshop on “Evidence-based Toxicology for the 21st Century: Opportunities and Challenges” in Research Triangle Park, North Carolina, USA on January 24-25, 2012. The presentations largely reflected two EBTC priorities: to apply evidence-based methods to assessing the performance of emerging pathwaybased testing methods consistent with the 2007 National Research Council report on “Toxicity Testing in the 21st Century” as well as to adopt a governance structure and work processes to move that ...


The Development And Validation Of An Ideal Point Measure Of Work Engagement, Michael M. Denunzio Sep 2019

The Development And Validation Of An Ideal Point Measure Of Work Engagement, Michael M. Denunzio

Dissertations, Theses, and Capstone Projects

Work engagement has been an extremely popular area of research and practice over the past two decades. However, organizational scholars have yet to thoughtfully consider alternative and potentially more appropriate ways of modeling how individuals report their work engagement and, relatedly, measuring the construct. This dissertation seeks to establish and support the position that (1) individuals use an ideal point (vs. dominance) process to identify how engaged they are and respond to work engagement items, and (2) an ideal point framework can be used to develop a construct valid work engagement scale with good psychometric properties. Since no such scale ...


Evaluating Existing Manually Constructed Natural Landscape Classification With A Machine Learning-Based Approach, Rok Ciglic, Erik Strumbelj, Rok Cesnovar, Mauro Hrvatin, Drago Perko Jun 2019

Evaluating Existing Manually Constructed Natural Landscape Classification With A Machine Learning-Based Approach, Rok Ciglic, Erik Strumbelj, Rok Cesnovar, Mauro Hrvatin, Drago Perko

Journal of Spatial Information Science

Some landscape classifications officially determine financial obligations; thus, they must be objective and precise. We presume it is possible to quantitatively evaluate existing manually constructed classifications and correct them if necessary. One option for achieving this goal is a machine learning method. With (re)modeling of the landscape classification and an explanation of its structure, we can add quantitative proof to its original (qualitative) description. The main objectives of the paper are to evaluate the consistency of the existing manually constructed natural landscape classification with a machine learning-based approach and to test the newly developed general black-box explanation method in ...


Validating A Masculinity Scale In A Non-College Sample, Rubi Gonzales Jan 2019

Validating A Masculinity Scale In A Non-College Sample, Rubi Gonzales

Open Access Theses & Dissertations

Sexual assault in the United States is prevalent. One out of every six American women has been the victim of an attempted rape or complete rape. Previous research demonstrates that hypermasculine attitudes are positively predictive of sexual aggression toward women. In these studies, researchers have continued to utilize outdated and inappropriate measures like the Hypermasculinity Inventory (1984) to assess hypermasculinity. Measures that assess hypermasculinity have only been validated on college samples. A modern measure of masculinity is the Auburn Differential Masculinity Inventory-23 (Burk, Burkhart, & Sikorski, 2004), which has been validated in college samples. The present research evaluated the psychometric properties ...

Quantifying And Mapping The Supply Of And Demand For Urban Ecosystem Services, Chang Zhao May 2018

Quantifying And Mapping The Supply Of And Demand For Urban Ecosystem Services, Chang Zhao

Theses and Dissertations

The ecosystem services (ES) concept is meant to facilitate consideration of the value of nature in conservation and landscape management processes by translating ecosystem functions into human benefits. Incorporating the ES concept into policy and decision-making has proven difficult due to challenges in identifying, measuring, and locating services and in predicting the impacts of decisions upon them. ES mapping offers a key solution to increase our understanding of the spatial patterns of ES supply and demand and the spatial relationships between them, but may be challenging to implement given a lack of spatial data related to ES or existence of ...


Validation Of Virginia's Juvenile Risk Assessment Instrument, Jessica P. Schneider Jan 2018

Validation Of Virginia's Juvenile Risk Assessment Instrument, Jessica P. Schneider

Theses and Dissertations

Utilizing a validated risk assessment tool to predict future offending is recommended as best practices in corrections by a number of professional organizations (Latessa & Lovins, 2010). Guided by the risk-needs-responsivity model, risk assessment tools have evolved to help inform criminal justice practitioners by identifying offenders most in need of intervention or supervision, guiding the case plan to optimize outcomes (Bonta & Andrews, 2007). The Virginia Department of Juvenile Justice (DJJ) utilizes the Youth Assessment and Screening Instrument (YASI) at all stages of contact with youthful offenders, including intake, probation, commitment, and parole (DJJ, 2016). However, risk assessment instruments do not always generalize across populations (Schwalbe, 2007) and are not always used effectively for case planning decisions (Singh et al., 2014). This study focused on the accuracy, equity, and usage of YASI in the Virginia juvenile justice system. Findings suggested that YASI performed at the expected and adequate levels of predictive validity in comparison to existing research. The predictive validity of the overall and dynamic risk scores and levels was statistically equivalent for males and females, but the Community/Peers and Family domains had stronger predictive validity for males than females. The predictive validity was statistically equivalent for White and Black youth for overall risk levels and dynamic risk scores and levels; however, the predictive validity for the overall risk scores was higher for White youth than Black youth. Each domain had a positive correlation between risk and assignment as a case planning priority area with a wide variation in the strength of correlation. Future research should focus on instrumental validity, protective factors, inter-rater reliability, domain interactions and clusters, reoffense types and timing, additional group and geographical differences, weighting and scoring, service matching, recidivism reduction, and program evaluations ...


Graphic-Prompt Tasks For Assessment Of Academic English Writing Ability: An Argument-Based Approach To Investigating Validity, Yundeok Choi Jan 2018

Graphic-Prompt Tasks For Assessment Of Academic English Writing Ability: An Argument-Based Approach To Investigating Validity, Yundeok Choi

Graduate Theses and Dissertations

The graphic-prompt writing task, where one or multiple visual graphs are provided as source materials, is a type of integrated writing tasks that assesses test takers’ ability to incorporate information from the source(s) into their writing. Compared to reading-to-write and reading-listening-to-write tasks, the graphic-prompt writing task is utilized and researched to a limited extent, even though it holds promise for facilitating multimodal literacy (Jewitt, 2005, 2008) and avoiding construct underrepresentation (Messick, 1989) in L2 academic writing assessment (Lim, 2009). Therefore, the present dissertation study aims to validate score interpretations on the graphic-prompt writing task by taking an argument-based approach ...

Teacher Disposition Scale (Tds): Construction And Psychometric Validation, Conor West, Amanda Ann Baker, John F. Ehrich, Stuart Woodcock, Sahar Bokosmaty, Steven J. Howard, Michelle J. Eady

Faculty of Social Sciences - Papers (Archive)

Despite the growing prominence and importance of the field of teacher dispositions for addressing selection criteria and assessment in educational research, there is an absence of psychometrically evaluated instruments to facilitate investigations. Furthermore, research thus far has not explored the relationship between teacher dispositions and better student outcomes. To address this paucity, key dispositional factors conducive to successful teaching and learning were identified through interviewing high performing teachers. Based on the interview, data a 24-item Teacher Disposition Scale (TDS) was constructed consisting of five dimensions: Motivation to teach; Teacher efficacy; Willingness to learn; Conscientiousness; and Interpersonal and communication skill. The ...

Fandom In Politics: Scale Development And Validation, Won-Ki Moon Jan 2018

Fandom In Politics: Scale Development And Validation, Won-Ki Moon

Theses and Dissertations

Despite the importance of fandom in politics to understanding individuals’ political behaviors, reliable scales measuring political fandom are lacking. To fill this gap, the present study constructs and validates a new scale for political fandom. First, by reforming existed questions and making new questions, the author derived 42 questions belonging to seven dimensions as an initial item pool based on conceptualization. Second, to refine and develop the scale, the researcher conducted exploratory factor analysis and confirmatory factor analysis. According to the result of the studies, the final factor model of political fandom retained 25 questions and seven dimensions. In addition ...


Validation Of The Multilayered Gender Identity Questionnaires, Philip Eiseman Dec 2017

Validation Of The Multilayered Gender Identity Questionnaires, Philip Eiseman

Dissertations

Gender identity shapes the ways transgender adults experience themselves and relate to the world around them. Although research and theory suggest that gender identity is a multidimensional construct, most measures of gender identity have viewed gender as primarily a unitary construct tied to the gender binary. The aim of this study was to develop and validate the Multilayered Gender Identity Questionnaires (MGIQ), a set of measures of gender identity, in a sample of transgender adults. Qualitative data collected through focus groups with transgender adults (N = 7) helped refine and develop these measures. A series of analyses involving a larger sample ...


Conceptualization And Measurement Of Spirituality: Towards The Development Of A Nontheistic Spirituality Measure For Use In Health-Related Fields, Valerie M. Hoots Dec 2017

Conceptualization And Measurement Of Spirituality: Towards The Development Of A Nontheistic Spirituality Measure For Use In Health-Related Fields, Valerie M. Hoots

Electronic Theses and Dissertations

Relationships between spirituality and health outcomes are well supported in research; however, measurement of spirituality often reflects a Judeo-Christian framework and is predominantly theocentric, neglecting the increasing religious pluralism and non-traditional expressions of spirituality in the United States. A new measure of spirituality was based on a conceptualization of nontheistic spirituality that is understood to be a relatively stable motivational process entailing a search for sacred connection, with “sacred” being defined by individual perceptions and not necessitating divine association. Item development for the current instrument included an initial pool of 65 items and two phases of revision and content validation ...


Story Sharing For First-Generation College Students Attending A Regional Comprehensive University: Campus Outreach To Validate Students And Develop Forms Of Capital, Colby R. King, Jakari Griffith, Meghan Murphy Nov 2017

The Development And Validation Of An Automatic-Item Generation Measure Of Cognitive Ability, Hines Scott Apr 2017

The Development And Validation Of An Automatic-Item Generation Measure Of Cognitive Ability, Hines Scott

Doctoral Dissertations

Cognitive ability is perhaps the most studied individual difference available to researchers, being measured quickly and effectively while demonstrating a predictable influence on many life outcomes. Historically, the evolution of the psychometric study of cognitive abilities has pivoted on the development of new and better methodologies allowing for a more complete and efficient capture of intellect. For instance, recent advances in computer and Internet technology have largely replaced traditional pencil-and-paper methods, allowing for innovative item development and presentation. However, concerns regarding the potential adverse impact and test security of online measures of cognitive ability, particularly in unproctored situations, are well ...

The Effect Of Emotionally Validating And Invalidating Responses On Emotional Self-Efficacy, Gregory Witkowski

Walden Dissertations and Doctoral Studies

The power of abuse, either in childhood or in adulthood, is clear in many cases. Yet certain types of abuse are harder to detect and understand. Emotional invalidation is one type of abuse that is characterized by an incongruence or minimization of another person's emotions. This experimental study explored effects of emotional invalidation and emotional validation on people's level of emotional self-efficacy. Participants (n = 230) were recruited through Quest Mindshare using a survey created through SurveyMonkey, and randomly placed into 3 groups. All participants were given a survey that asked them to choose how certain pictures made them ...


Body Image And Sex: How Women's Body Image Influences And Impacts Sexual Experiences, Sarah E. Christian Jan 2017

Body Image And Sex: How Women's Body Image Influences And Impacts Sexual Experiences, Sarah E. Christian

Theses and Dissertations--Family Sciences

Body image, the subjective view about one’s own body and how others perceive it, has been shown to have numerous impacts on women in multiple facets of their lives, including sexual experiences. This study seeks to examine the specific impact that body image has on women using sexual relationships for self-validation. Findings suggest that the more likely a woman is to perceive herself as overweight, the higher the chance that she seeks out sex in order to validate her feelings with regards to her body. Parental involvement and comments about the participant’s body were also shown with the ...


Examining Illness Invalidation And Illness Perception In Relation To Physical Functioning In The Context Of Cardiovascular Disease, Jaclyn Ciera Turner Dec 2016

Examining Illness Invalidation And Illness Perception In Relation To Physical Functioning In The Context Of Cardiovascular Disease, Jaclyn Ciera Turner

USC Aiken Psychology Theses

Invalidation is defined as the perception of cognitive, affective, and behavioral responses of others that are experienced as denying, lecturing, overprotecting, not supporting, and not acknowledging with the respect to the condition of the patient (Kool, 2012). Invalidation has also been suggested to negatively impact patients’ physical health (Kool, 2012). One specific type of invalidation is illness invalidation (II), defined as attitudes of distrust, suspicion, lack of support for, or acknowledgement that a patient is suffering from an illness (Blom et al., 2011). In addition to II, illness perception (IP) is another construct that has been linked to negative physical ...

An Examination Of The Relationships Between Safety Culture Perceptions And Safety Reporting Behavior Among Non-Flight Collegiate Aviation Majors, Daniel Kwasi Adjekum, Julius Keller, Micah Walala, Cody Christensen, Randal J. Demik, John P. Young, Gary J. Northam

International Journal of Aviation, Aeronautics, and Aerospace

Some collegiate aviation programs in the United States have adopted the voluntary Safety Management System (SMS) strongly advocated by the Federal Aviation Administration to build a proactive safety culture. While relevant safety culture research has primarily focused on flight personnel, there has been limited investigation on non-flight collegiate aviation majors (collegiate air traffic control, aviation management, and unmanned aerial systems students) perceptions on collegiate aviation safety. This study examined the relationship between safety culture perceptions and safety reporting behavior of non-flight major students at five collegiate aviation programs. One hundred and sixteen completed responses to a validated safety culture perception ...


Food For Thought … Mechanistic Validation, Thomas Hartung, Sebastian Hoffman, Martin Stephens Jul 2016

Food For Thought … Mechanistic Validation, Thomas Hartung, Sebastian Hoffman, Martin Stephens

Martin Stephens, PhD

Validation of new approaches in regulatory toxicology is commonly defined as the independent assessment of the reproducibility and relevance (the scientific basis and predictive capacity) of a test for a particular purpose. In large ring trials, the emphasis to date has been mainly on reproducibility and predictive capacity (comparison to the traditional test) with less attention given to the scientific or mechanistic basis. Assessing predictive capacity is difficult for novel approaches (which are based on mechanism), such as pathways of toxicity or the complex networks within the organism (systems toxicology). This is highly relevant for implementing Toxicology for the 21st ...
