"All things at once": A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals

The purpose of this phenomenological study was to explore how individuals from different multiracial/multiethnic groups experience and process the phenomenon of parental racial ethnic socialization (RES). Critical multiracial race theory, critical race theory, and bioecological systems theory offered a conceptual framework to how RES is often presented and processed. This study was guided by two research questions: (1) What are the experiences of RES among multiracial individuals? and (2) How do multiracial individuals process the parental racial ethnic socialization they were offered? Nine qualitative, one-on-one, semistructured interviews were conducted with individuals from three different multiracial/multiethnic groups. Results revealed that experiences of RES varied along with how participants processed RES. Three subthemes and one theme emerged related to the RES experiences of participants. For some participants lack of conversations were evident in their RES, which meant that conversations surrounding multiraciality and other racialized topics were not present. Other participants disclosed the subtheme of preparedness as part of their RES experience, while others mentioned the importance of environment to their RES experience. Additionally, the theme of changes over time arose, demonstrating how different life events can impact RES experiences. As for how multiracial/multiethnic individuals process RES experiences, the main theme of identity …

Bringing Them Back: Using Latent Class Analysis to Re-Engage College Stop-Outs

Half of the students who begin college do not complete a degree or certificate. The odds of completing a degree are decreased if a student has a low socio-economic status (SES), is the first in a family to attend college (first-generation), attends multiple institutions, stops out multiple times, reduces credit loads over time, performs poorly in major-specific coursework, has competing family obligations, and experiences financial difficulties. Stopping out of college does not always indicate that a student is no longer interested in pursuing an education; it can be an indication of a barrier or several barriers faced. Institutions can benefit themselves and students by utilizing person-centered statistical methods to re-engage students they have lost, particularly those near the end of their degree plan. Using demographic, academic, and financial variables, this study applied latent class analysis (LCA) to explore subgroups of seniors who have stopped out of a public four-year Tier One research intuition before graduating with a four-year degree. The findings indicated a six-class model was the best fitting model. Similar to previous research, academic and financial variables were key determinants of the latent classes. This paper demonstrates how the results of an LCA can assist institutions in the decisions …

Evaluating Program Diversity and the Probability of Gifted Identification Using the Torrance Test of Creative Thinking

Multiple criteria systems are recommended as best practice to identify culturally, linguistically, economically diverse students for gifted services, in which schools often incorporate measures of creativity. However, the role of creativity in identification systems and its recruitment of diverse student populations is unclear. The Torrance Test of Creative Thinking (TTCT) is the most widely used norm-referenced creativity test in gifted identification. Although commonly used for identifying talent, little is known on the variability in composite scores on the TTCT-Figural and student demographics (i.e., race/ethnicity, sex, socioeconomic status, English language learning status). This study evaluated student demographic subgroup differences that exist after the initial phase of an identification process (i.e., universal screening, referrals) and examined the relationship among student demographics (i.e., race/ethnicity, free/reduced lunch status, English language learning status, sex), cognitive ability, academic achievement, and creativity, as measured by the TTCT-Figural Form A or B, to the probability of being identified for gifted programs. In a midsized school district in the state of Texas, findings indicate several demographic differences for students who were referred or universally screened across the measures of cognitive ability, academic achievement, and creativity. However, there were lower differences when using the TTCT-Figural. Results of a hierarchical generalized …

Exploring the Impacts of Social Media Use on Young Adults' Self-Esteem and Perceived Impact on Psychological Diagnoses or Emotional Disturbance Eligibility

The impacts of emerging adults' social media use have been shown as generally negative, especially in decreasing their self-esteem and self-concept and increasing anxiety, depression, and more. Although there is research on social media's impact on various communities of adolescents and young adults, limited research has focused on this effect for young adults with mental health diagnoses or served under IDEA's emotional disturbance eligibility criteria. Additionally, no research has studied this topic during the COVID-19 pandemic. Therefore, the purpose of the current study is to examine how various types of social media use impact young adults' self-esteem, including those who are psychologically vulnerable. Participants included 119 individuals, 18 to 19-years of age, with and without mental health diagnoses or Emotional Disturbance special education eligibility recruited utilizing social media pages and social media hashtags. Participating individuals answered demographic and social media use questions and completed the Rosenberg Self-Esteem Scale to provide information about self-esteem. Additionally, participants responded to questions regarding what role they feel social media use has had on their mental health, including contribution to or exacerbating their symptoms. Univariate statistics were run to control demographic factors and determine the percentage of participants who believe social media has negatively affected …

Flipping Scripts: Mentoring for Secondary Readers (open access)

Flipping Scripts: Mentoring for Secondary Readers

Researchers have reported that a variety of socio-cultural interventions can be used to increase positive attitudes toward reading for secondary students. A socially constructed reading intervention could add learning growth for a reluctant reading population. This study examines whether secondary students experience a measurable increase in positive attitudes toward reading after engaging in modeling and mentoring sessions with a much younger student and whether there is a perceivable difference in the secondary students' attitude following this mentoring activity. A variation of the one-way ANOVA, the Mann-Whitney U test, was completed to determine whether there was a statistically significant difference between these groups of students after participating in the reading intervention plan. It was determined that a small increase was found in one of the domains. The measurement survey is divided into four measured components that align with Albert Bandura's model for self- efficacy. The results from this study indicated growth in only one of the measures, however, some of the outcomes in the other measures suggested potential growth in attitudes with a relaxation of these necessary experimental strictures. A limitation of this research was the change from face-to-face tutoring completed by the secondary student with elementary students in an afterschool …

Lived Experiences of Families of University Students Amid a Pandemic Response

This study explores students' and their families' experiences during the pandemic response to COVID-19 by the higher education community. Using the hermeneutic phenomenological approach, we employed two open-ended surveys and semi-structured interviews of 16 parent-college student dyads (N = 34). The study draws on students' and parents' retrospective accounts beginning Spring 2020 through the Fall 2020 semesters. Families experienced a disruptive event initialized by the ebb and flow of information. Students' experiences varied based on their expectations and academic classification. The most consistent family challenges were the displacement of students and parents from their physical education and work locations while having to maintain student and occupation responsibilities. The educational experience was inconsistent and dependent on each professors' capacity to engage the students in the online environment. Students expressed feelings of loss of their student and educational experiences, but most students felt the spring courses prepared them to continue their education. Assignments due at random times and poor communication about expectations inhibit students from having dedicated time to interact and make memories. Most families adapted to the new normal by supporting the family members' identities as students and employees and ensuring everyone had the resource needed to succeed. Families experienced monotony …

A Multi-Site Case Study of Middle School Reading Teachers' Perceptions of the Impact of Response to Intervention

Early reading intervention has not eradicated reading deficiencies at the middle school level. According to the National Center for Educational Statistics (NCES), adolescents continue to read below grade level in middle grades. Response to intervention (RTI) is one method of combating this educational concern. This study examined the impact of implementation of a RTI program within one district across multiple middle school campuses. Using individual structured online questionnaires, focus groups, and document analysis, the researcher employed a qualitative, multi-site case study design to evaluate the perceptions of impact of RTI through the lens of middle school reading teachers. Participants included a convenient purposive sample of middle school reading teachers in a suburban school district of about 24,000 students in North Central Texas. I present a review of relevant research at the middle school level to provide a framework for the current study. Additionally, an outline of methodology, research questions, and the proposed data analysis plan are provided. I discuss the intended use of constant comparative analysis to report findings in themes. Particularly, facilitators, hindrances, and impact are a priori themes for reporting.

Using a Slopes Difference Test to Probe Longitudinal Multilevel Interactions in an Aptitude-Treatment or Skill-by-Treatment Context: A Simulation

In order to determine which interventions work best for which students, precision education researchers have examined aptitude-treatment interactions (ATI) or skill-by-treatment interactions (STI) by using multiple regression analysis. In recent years, technological innovation and greater accessibility to more advanced statistical techniques have allowed researchers to examine ATI or STI using longitudinal mixed modeling. Probing techniques for interaction effects like slopes difference tests fit well with an ATI or STI framework, but the power of using a slopes difference test in longitudinal mixed models is unknown. The current study used the simulation method to determine which factors influence the power of a slopes difference test in a longitudinal mixed model. Specifically, the study examined design conditions such as number of waves, number of clusters and participants per cluster, effect size, intraclass correlation, variances and covariance of the random effects, and proportion of treatment to non-treatment participants. These were examined in order to help ATI and STI researchers understand whether the slopes difference test in a longitudinal mixed model is sufficiently powered for their sample and study. Effect size, number of waves, number of clusters, and participants per cluster were found to be strong determinants of power and significantly impacted model convergence …

Coaching Athletes with Post-Traumatic Stress: Exploring Trauma-Related Competencies and Coaching Efficacy (open access)

Coaching Athletes with Post-Traumatic Stress: Exploring Trauma-Related Competencies and Coaching Efficacy

The purpose of this study was twofold: (a) assess cycling coaches' trauma-related competencies, as measured by trauma knowledge (i.e., trauma-specific education, familiarity with post-traumatic stress [PTS]), stigma of persons with PTS (i.e., fear/dangerousness, help/interact, forcing treatment, negative emotions), and interpersonal skills (i.e., self-reported emotional intelligence, perceived quality of coach-athlete relationships); and (b) examine the influence that trauma knowledge and stigma of persons with PTS has on coaching efficacy specific to coaching trauma-impacted athletes (i.e., trauma-informed coaching efficacy), after controlling for general coaching experience. Descriptive statistics indicated the majority of coaches had no trauma-specific education, a high degree of familiarity with PTS, and a low level of stigma via four attribution variables. Moreover, participants highly appraised their own emotional intelligence, the quality of their coach-athlete relationships, and their trauma-informed coaching efficacy. A hierarchical regression analyses indicated that familiarity with PTS helped to explain additional variance in trauma-informed coaching efficacy over and above demographic and general coach experience variables. The study establishes trauma-informed coaching as a distinct area of research and highlights the need for improved continuing education opportunities for coaches related to psychological trauma and PTS.

Factor Retention Strategies with Ordinal Variables in Exploratory Factor Analysis: A Simulation

Previous research has individually assessed parallel analysis and minimum average partial for factor retention in exploratory factor analysis using ordinal variables. The current study is a comprehensive simulation study including the manipulation of eight conditions (type of correlation matrix, sample size, number of variables per factor, number of factors, factor correlation, skewness, factor loadings, and number of response categories), and three types of retention methods (minimum average partial, parallel analysis, and empirical Kaiser criterion) resulting in a 2 × 2 × 2 × 2 × 2 × 3 × 3 × 4 × 5 design that totals to 5,760 condition combinations tested over 1,000 replications each. Results show that each retention method performed worse when utilizing polychoric correlation matrices. Moreover, minimum average partials are quite sensitive to factor loadings and overall perform poorly compared to parallel analysis and empirical Kaiser criterion. Empirical Kaiser criterion performed almost identical to parallel analysis in normally distributed data; however, performed much worse under highly skewed conditions. Based on these findings, it is recommended to use parallel analysis utilizing principal components analysis with a Pearson correlation matrix to determine the number of factors to retain when dealing with ordinal data.

Measurement Invariance of a Posttraumatic Stress Disorder Symptoms Measure (PCL-5) in College Student and Amazon's Mechanical Turk Samples (open access)

Measurement Invariance of a Posttraumatic Stress Disorder Symptoms Measure (PCL-5) in College Student and Amazon's Mechanical Turk Samples

College student and Amazon's Mechanical TURK (MTURK) samples are regularly utilized in trauma research. Recent literature, however, has criticized these samples for not being generalizable to the general U.S. population. Measurement invariance (MI) using confirmatory factor analyses (CFA), is rarely utilized in trauma research, even though the analysis can determine whether groups are invariant across factor structure, factor loadings, item intercepts, and residual error variances on a given measure of PTSD symptom severity. The purpose of this study was to determine whether college student (n = 255) and MTURK (n = 316) samples are invariant on the PCL-5. Model fit indices indicated the 7-factor Hybrid model was the best fitting model, but the 6-factor anhedonia model was the most parsimonious model. Both models demonstrated equivalence in factor structures (configural invariance), factor loadings (metric invariance), intercepts (scalar invariance), and residuals (strict invariance), indicating MTURK and college student samples are similar in regards to PTSD symptom severity. These findings provide evidence that these groups can be combined in future studies to increase sample size for trauma research. Only the Anhedonia factor exhibited mean differences between groups, which may be related to true differences between college students and MTURK survey-takers. Thus, there is …

Mixed Development and Validation of an Authentic Assessment for Middle School Mathematics (open access)

Mixed Development and Validation of an Authentic Assessment for Middle School Mathematics

In response to concerns about using only standardized multiple-choice assessments, some school districts have moved to using alternative ratings of student achievement with authentic assessments. However, such assessments are often limited in terms of the psychometric validity data supporting their use. The present study mixed quantitative and qualitative methods to examine the validity, development, and refinement of an authentic rating approach currently in use in middle school mathematics classes from a large suburban school district in the Southwest United States. A sample of teachers (n = 14), rated students (n = 110) using a pilot rubric of 187 items. Analyses resulted in a 32-item rubric with 20 themes and 9 factors. Results from a G-study revealed the facet that best explained variance in student scores was the interaction between raters and assessment units, as well as students and assessment units. As part of the development of the assessment, a content validity exercise revealed 18% of the rubric items as below average quality. Findings highlight the need to enhance contextualization of rubrics, use a strategy of assessment that includes contextualized and decontextualized assessment, and to investigate the role of utilization deficiency in explaining low student scores.

Mothers' Parenting Stress in Chinese Immigrant Families: The Role of Fathers' Involvement and Social Support

This study investigated the association between Chinese immigrant mothers' reports of parenting stress and two sources of parenting support: fathers' support and social support. Five independent-samples t-tests were first computed to examine whether there were discrepancies between Chinese immigrant mothers' and fathers' perceptions of fathers' involvement across five domains of fathers' involvement in early child care: (1) fathers' warmth and attunement; (2) control and process responsibility; (3) emotional involvement; (4) indirect care; and (5) positive engagement. Then regression analyses were conducted to understand how and to what extent the five domains of father involvement reported by mothers and mothers' perceived social support influenced Chinese immigrant mothers' parenting stress. In addition, an indirect effects of mothers' self-efficacy on the relation between fathers' involvement and mothers' parenting stress was also tested. The results showed that Chinese mothers reported significantly greater level of fathers' emotional involvement than the same type of involvement reported by Chinese immigrant fathers. This study also found that fathers' emotional involvement reported by Chinese immigrant mothers was a significant predictor of Chinese immigrant mothers' parenting stress. However, mothers' perceived social support was a stronger predictor, accounting for more variance in their parenting stress than their reports of fathers' involvement …

The Effects of Participant Motivation on the Effectiveness of Video Modeling

Video modeling interventions have been mostly effective for individuals with autism spectrum disorder (ASD) in teaching social communication skills. However, differences in the effectiveness of these interventions have been noted. Participant motivation was suggested as one of the factors that can influence the effectiveness of video modeling. The purpose of this study was to investigate the effects of participant motivation on video modeling for teaching social communication skills to individuals with ASD. A combined multiple probe across participants and adapted alternating treatments design was used to examine the differential effects of two video modeling conditions (i.e., motivated and non-motivated) on social communication skills of four adults with ASD. Of the four participants, three participants responded to the intervention and performed more of target behavior during the motivated video modeling condition than the non-motivated video modeling condition, while one did not respond to the intervention. In addition, the three participants engaged in a higher percentage of the target behavior during motivated generalization sessions than non-motivated generalization sessions. The results demonstrated that participant motivation influenced the effectiveness of video modeling.

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8

This study was intended to evaluate the impact of socioeconomically disadvantaged children's participation in the Texas Home Instruction for Parents of Preschool Youngsters (TX HIPPY) Program on their school readiness and academic achievement. The study used a quasi-experimental design and applied full and optimal propensity score matching (PSM) to address the evaluation concern of the impact of the TX HIPPY program on HIPPY participants' academic achievement compared to non-HIPPY participants. This evaluation targeted former HIPPY participants and tracked them in the Dallas ISD database through Grade Levels K-8. Data were obtained by administering Istation's Indicators of Progress (ISIP) for kindergarten, TerraNova/SUPERA for Grades K-2, and State of Texas Assessments of Academic Readiness for math and reading (STAAR) for Grades 3-8. HIPPY and non-HIPPY groups were matched using propensity score analysis procedures. The evaluation findings show that the TX HIPPY program positively influences kindergarten students to start school ready to learn. The findings of math and reading achievements suggest that HIPPY children scored at the same level or higher than non-HIPPY children did on math and reading achievement, indicating that TX HIPPY program has achieved its goal of helping children maintain long-term academic success. However, the evaluation findings also indicated that …

Reaping the Seeds of Leadership: Evaluating a Proposed Model of Lifespan Leadership Development

Though research suggests that several factors are related to the onset of leadership, few researchers have endeavored to determine how these factors may interact to bring about early leadership development. A descriptive discriminant analysis was conducted to test the validity of early factors cited by Murphy and Johnson; namely, lower scores on measures of temperamental negative affect, higher scores of temperamental extraversion, effortful control, orienting sensitivity, authoritative parenting style, secure adult attachment, older relative age, and more reported team sports and extracurricular activities experiences were hypothesized to predict current and past leaders versus never leaders. Additional analyses investigated possible gender differences in how these early factors may predict leader occupancy. The results indicate that early factors are able to predict leadership status for male students, though a majority of the variance in leader status is still left unaccounted. Implications for future leadership development research and training are discussed.

Reporting the Performance of Confidence Intervals in Statistical Simulation Studies: A Systematic Literature Review

Researchers and publishing guidelines recommend reporting confidence intervals (CIs) not just along with null hypothesis significance testing (NHST), but for many other statistics such as effect sizes and reliability coefficients. Although CI and standard errors (SEs) are closely related, examining standard errors alone in simulation studies is not adequate because we do not always know if a standard error is small enough. Overly small SEs may lead to increased probability of Type-I error and CIs with lower coverage rate than expected. Statistical simulation studies generally examine the magnitude of the empirical standard error, but it is not clear if they examine the properties of confidence intervals. The present study examines confidence interval investigating and reporting practices, particularly with respect to coverage and bias as diagnostics in published statistical simulation studies across eight psychology journals using a systematic literature review. Results from this review will inform editorial policies and hopefully encourage researchers to report CIs.

Creative Self-Efficacy and Personality: From Imagination to Creativity

Imagination and creative self-efficacy are important components of the creative process and outcomes but are rarely investigated together. To explore the relationship between personality factors, imaginative thinking, and creative self-efficacy, survey responses were gathered from university students in a southwestern region in the United States (n = 1,731). Personality was measured using the International Personality Item Pool (IPIP), imagination was measured using the Imaginative Capability Scale (ICS), and creative self-efficacy was measured using items based on reliability in previous studies. Participants were asked to complete the three surveys along with demographic information through an online format. Confirmatory factor analysis (CFA) was conducted first to confirm measurements used. After fit indices confirmed measurement models used, subsequent analyses were conducted using structural equation modeling (SEM). The model of best fit supported creative self-efficacy as a strong predictor of all three factors of imagination. Additionally, the model indicated a strong relationship between conscientiousness and conceiving imagination as well as other notable relationships with personality factors.

Measurement of Fidelity and Social Validity: Caregiver Application of Trial-Based Functional Analysis Procedures

The present study utilized multiple-baseline and multi-probe across participants designs to measure both fidelity and efficacy of caregivers as primary interventionists when using trial-based functional analysis (TBFA) procedures. Participants included any caregiver of a child with a medical or educational diagnosis of autism and challenging behavior. Caregiver fidelity of implementation of TBFA procedures was measured across three phases: baseline, training, and independent implementation or generalization. Within the implementation phase, caregivers independently conducted TBFAs on their respective children within the home setting. Fidelity, efficacy, and social validity across each participant were measured. Each caregiver was able to reach fidelity during the training phase, and three out of five caregivers were able to identify a clear behavior function for their child's behavior within the implementation phase of the study. Social validity was evaluated. Results indicate that caregivers may be able to supplement traditional interventionists during the TBFA process. Implications for future practice are reviewed.

Preservice Special Education Teachers' Sense of Preparedness to Instruct English Learners with Disabilities

This study examines the sense of preparedness of preservice special education teachers (PSETs) to instruct English language learners. Pre- and post-survey measures were analyzed using the Wilcoxon signed-rank tests for a group of PSETs as they engaged in their second semester of student teaching experience. To explore emerging themes, a post-qualitative analysis was performed using focus groups. Quantitative results revealed no statistical difference except for the Self-Efficacy subscale. Focus group data showed increased confidence levels resulting from the student teaching experience. A Mann-Whitney U test was used to compare pre-survey results between PSETs who had and PSETs who had not taken advanced coursework or participated in student teaching. With the exception of the subscale, Attitude Towards ELs in the Classroom, results revealed no statistical difference between the two groups. At the same time, qualitative, open-response questions revealed PSETs who had participated in advanced coursework and student teaching seemed to have a deeper understanding of ELs' instructional and linguistic needs. Contributions to the literature are presented which may help in designing teacher preparation programs to increase PSETs' sense of preparedness to better serve ELs with disabilities.

Grounded in self-determination theory and achievement goal theory, the purpose of this mixed-methods study was to examine the underlying motivational processes from social environments created by coaches, peers, and parents to motivational outcomes in high school athletes, with an emphasis on the relative influence of social agents in basic psychological needs (i.e., autonomy, competence, and relatedness). The quantitative part of this study tested a hierarchical model of high school sport motivation in a final sample of 311 student athletes (204 boys, 107 girls) using structural equation modeling: social factors (coach-, peer-, and parent-created motivational climates) -> psychological mediators (need satisfaction and frustration) -> types of motivation (autonomous motivation, controlled motivation, and amotivation) -> consequences (subjective vitality, athlete burnout, and intention to drop out). Invariance across gender and across team type (varsity vs. non-varsity) was also tested. Adequate model fits were achieved in separate "brighter side" and "darker side" models across the overall sample, gender, and team type.

Comparing Three Approaches for Handling a Fourth Level of Nesting Structure in Cluster-Randomized Trials

This study compared 3 approaches for handling a fourth level of nesting structure when analyzing data from a cluster-randomized trial (CRT). CRTs can include 3 levels of nesting: repeated measures, individual, and cluster levels. However, above the cluster level, there may sometimes be an additional potentially important fourth level of nesting (e.g., schools, districts, etc., depending on the design) that is typically ignored in CRT data analysis. The current study examined the impact of ignoring this fourth level, accounting for it using a model-based approach, and accounting it using a design-based approach on parameter and standard error (SE) estimates. Several fixed effect and random effect variance parameters and SEs were biased across all 3 models. In the 4-level model, most SE biases decreased as the number of level 3 clusters increased and as the number of level 4 clusters decreased. Also, random effect variance biases decreased as the number of level 3 clusters increased. In the 3-level and complex models, SEs became more biased as the weight level 4 carried increased (i.e., larger intraclass correlation, more clusters at that level). The current results suggest that if a meaningful fourth level of nesting exists, future researchers should account for it using …

Developing a Self-Respect Instrument to Distinguish Self-Respect from Self-Esteem

Throughout the scientific literature, researchers have referred to self-respect and self-esteem as being the same construct. However, the present study advocated that they exist as two distinct constructs. In this quantitative study, an instrument was developed to measure self-respect as a construct, and subsequently distinguish that self-respect is distinct from the construct of self-esteem. Exploratory factor analyses (EFA) indicated 32.60% of the variance was accounted for by the 11-item Jefferson Self-Respect instrument (JSR), which measured self-respect as a unidimensional construct. The reliability estimate of the scores from the JSR reached an acceptable α = .82. Fit indices (RMSEA = .031, SRMR = .037, CFI = .982, and TLI = .977) from the confirmatory factor analyses (CFA) signified a well-fitted hypothesized model of self-respect that existed as a unidimensional construct. Additionally, the CFA revealed that the construct of self-respect, and self-esteem was generally distinct, and the strength of the correlation between the two constructs was moderately positive (r = .62).

How Attitudes towards Statistics Courses and the Field of Statistics Predicts Statistics Anxiety among Undergraduate Social Science Majors: A Validation of the Statistical Anxiety Scale

The aim of this study was to validate an instrument that can be used by instructors or social scientist who are interested in evaluating statistics anxiety. The psychometric properties of the English version of the Statistical Anxiety Scale (SAS) was examined through a confirmatory factor analysis of scores from a sample of 323 undergraduate social science majors enrolled in colleges and universities in the United States. In previous studies, the psychometric properties of the Spanish and Italian versions of the SAS were validated; however, the English version of the SAS had never been assessed. Inconsistent with previous studies, scores on the English version of the SAS did not produce psychometrically acceptable values of validity. However, the results of this study suggested the potential value of a revised two-factor model SAS to measure statistics anxiety. Additionally, the Attitudes Towards Statistics (ATS) scale was used to examine the convergent and discriminant validities of the two-factor SAS. As expected, the correlation between the two factors of the SAS and the two factors of the ATS uncovered a moderately negative correlation between examination anxiety and attitudes towards the course. Additionally, the results of a structural regression model of attitudes towards statistics as a predictor …
