about the ReCentering Psych Stats and Transforming Research
Methods in Health Services Psychology approaches and
projects.
My (this is Lynette Bikos) participation in the Academics for Black
Survival and Wellness initiative served as a clarion call for
addressing systematic racism in the academy. Throughout the initiative,
A4FL presenters described the problem of centering
whiteness.
To center a variable in regression means to set its value at zero and
interpret all other values in relation to this reference point.
Regarding race and gender, researchers often center male and White at
zero. Further, it is typical that research vignettes in statistics
textbooks are similarly seated in a White, Western (frequently U.S.),
heteronormative, framework.
Pairing the statistical notion of centering with the
challenge to decenter whiteness caused me to (a) immediately
change how I teach statistics, (b) formally evaluate the changes that I
made, and (c) begin the steps in creating an open education resource
(OER).
Teaching and Evaluating a ReCentered Stats Class
I teach four “stats n’ methods” classes in the Clinical and
Industrial/Organizational Psychology doctoral programs. These
include:
- Research Methods I: Analysis of Variance
- Research Methods III: Multivariate Modeling
- Research Methods IV: Psychometrics and Theory of Test
Construction
- Qualitative Research Methods (only I/O students are required to take
this course)
Expecting that we will make mistakes and continue to learn,
recentering the stats classes to this point have involved:
- Creating a classroom climate that makes space for all bodies and
voices
- Naming and addressing practices that perpetuate institutional racism
in both the university and larger profession of psychology
- Reducing the costs by
- using freely available OERS or through the campus library and
- teaching with R (and other freely available apps) so that
post-doctorally, students will be equipped to continue as
scientist-practitioners-advocates (the transition from SPSS to
R began in 2017)
- Incorporating principles of universal design, such as
- including captioning with screencasted lectures that are viewed
prior to classtime
- adhering to principles of text formatting that work best with
screenreaders
- Selecting research vignettes from the published literature where
- the author’s identity is from a group where scholarship is
historically marginalized (e.g., BIPOC, LGBTQ+, emerging nations),
- the research has a focus on justice, equity, diversity, inclusion,
and contributes to a social justice pedagogy,
- the lesson’s statistic is used in the article, and
- the data is shared publicly or there is sufficient information in
the article to simulate the data for the chapter examples) and practice
problem(s)
- Modeling and incentivizing participation in open science through
pre-registration, data/code sharing, and learning to collaborate in
cloud-environments (e.g., SharePoint, GitHub, OSF)
At the end of Fall Quarter 2020, I added three additional items were
added to the institution’s course evaluations for the students enrolled
in the fall quarter stats courses. So that we could analyze the effects
across time, all students who were enrolled in the doctoral programs
were sent information about a proposed mixed methods evaluation of the
decolonization efforts and given an opportunity to “opt out” of having
their de-identified course evaluation data used in the evaluation.
Analysis is presently underway. Consensual qualitative research -
modified (Spangler et al., 2012) is being used to
analyze the short, narrative responses to the questions about
decolonization. Heirarchical linear regression is being used to evaluate
the incremental effects of the student’s department (clinical vs. I/O),
the statistics package being taught (SPSS vs. R), and the intentional
approaches to decolonizing the curriculum (precentered
vs. recentered).
ReCentering Psych Stats: the OER (textbook)
The experience of locating freely available materials for teaching
the statistics class made clear the need for resources that are
recentered (as described above), but are also written for the
scientist-practitioner-advocate in that they:
- use R
- provide a workflow through the statistic
- identify common problems (e.g., missingness) and demonstrate
approaches to address them
- are connected to published works so that the student can see how the
statistic that is the focus of the lesson fits into the larger analytic
picture
- demonstrate how to write up the results in APA style
At this stage, I have created first drafts of four mini-volumes of
lessons used in my doctoral level statistics courses (copyediting is
still required). These include:
- Analysis of
Variance with chapters on
- Orientation to R (two chapters)
- One-way ANOVA
- Factorial (between-subjects) ANOVA
- One-way repeated measures ANOVA
- Mixed design ANOVA
- Analysis of covariance (ANCOVA)
- Multivariate
Modeling with chapters on
- Cleaning and formatting data
- Scoring data
- Data diagnostics
- Multiple imputation
- Simple mediation
- Complex (parallel, serial) mediation
- Simple moderation
- Conditional process analysis (moderated mediation)
- Multilevel
Modeling with chapters on
- Nested within groups (including using compositional effects as an
approach to analysis)
- Preparing data for nesting within persons (repeated measures)
- Longitudinal modeling
- Considerations for clocking time
- Psychometrics
with chapters on
- Questionnaire construction
- Survey development in Qualtrics
- Validity
- Reliability
- Item analysis for educational achievement exams
- Item analysis for Likert type scales
- Principal components Analysis
- Principal axis Factoring
- Confirmatory factor analysis: First order models
- Confirmatory factor analysis: Hierarchical and nested models
- extRas is emerging,
presenting offering chapters on
- The process of building a book with R Markdown, bookdown, GitHub,
and GitHub pages
- The “go-to” formatting techniques used to create ReCentering Psych
Stats
To challenge my R skills, I am writing the textbook (and this
website) in RMarkdown (with the bookdown package), serving it to the
Github, and posting it through Github Pages.
Collaboration is welcome! This could include:
- reviewing/editing chapters via the Github repository,
- recommending articles as research vignettes,
- collaborating on a lesson if you are co-author to a chapter that is
included in the OER.
