Research Byte: #Measurementinvariance of the #Woodcock-Johnson® V (#WJV) Achievement Battery: An Exploratory Graph Analysis (#EGA) Approach - #schoolpsychology #schoolpsychologists #sld #SPED #achievement

 

Journal of Psychoeducational Assessment

Abstract

The Woodcock-Johnson V (WJ V) test evaluates general intelligence and cognitive abilities using the Cattell–Horn–Carroll (CHC) theory framework. While measurement invariance is often tested using structural equation modeling (SEM), few studies have applied exploratory graph analysis (EGA), particularly in intelligence assessments. This study addresses that gap by examining configural and metric invariance of the WJ V achievement battery across age, race, and gender using normative data and a novel EGA approach. Results show that the WJ V maintains a consistent structure across diverse groups, supporting its validity in measuring the same constructs. Stability analyses further supported these findings, with test-to-community assignments remaining highly consistent in bootstrapped samples. Minor variation was observed only in the Oral Language Sample, which showed slightly lower but acceptable stability above 0.70.

Conflict of interest disclosure.  I’m the senior non-royalty earning author of the WJ V, which means I’ve already received payment for my services and don’t make a penny on any sales.

CHC Theory (2009) article hits 2000+ citations. Thanks.

2005 citations since 2009!!!!!

On occasion I check my Google Scholar profile.  Yesterday I was pleased to see that my most frequently cited peer-reviewed journal article (CHC theory and the human cognitive abilities project: Standing on the shoulders of the giants of psychometric research—Intelligence) had achieved the 2000+ (n=2005) total reference citations mark.  This clearly has been my most important peer-reviewed journal contribution to the field of intelligence and human cognitive abilities.

Thanks to all who have found the article useful.  And a special thanks to Dr. Doug Detterman.  After making an ISIR presentation about this topic, Doug, who was then the editor of Intelligence, invited me to submit an article.

National Academies report: Blueprint for national prevention infrastructure for #mental #emotional #behavioraldisorders

Available to download for free at this link.


SUMMARY

Substance use disorder and overdose, suicide, and youth mental illness are major public health crises that cost the United States in lives, human potential, productivity, and resources. Government agencies at the federal, state, tribal, and local levels work together with health care entities, academic institutions, communities, and community-based organizations to respond to these crises largely with treatment and recovery services. Mental, emotional, and behavioral (MEB) disorders are mental and substance use disorders and associated problem behaviors, even if they do not meet diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th ed. Less attention and fewer resources are dedicated to delivering services specifically devoted to preventing such disorders and promoting MEB health and overall well-being. Greater support for prevention could minimize the pain and suffering associated with MEB disorders, and, critically, reduce the burden on overtaxed treatment and recovery systems.

This report provides a blueprint to develop the infrastructure to deliver programs that reduce risk factors (characteristics associated with a higher likelihood of negative outcomes) and promote protective factors (characteristics that can reduce the negative impact of a risk factor and promote better outcomes) for MEB disorders across the life course and in an array of settings. The committee’s charge was to outline the components and requirements of a well-functioning infrastructure to support the delivery of evidence-based programs at federal, state, tribal, and local levels.
