How Important is the Choice of Bandwidth in Kernel Equating?.

Applied psychological measurement

Wallin G, Häggström J, Wiberg M.
PMID: 34866710
Appl Psychol Meas. 2021 Oct;45(7):518-535. doi: 10.1177/01466216211040486. Epub 2021 Oct 20.

Kernel equating uses kernel smoothing techniques to continuize the discrete score distributions when equating test scores from an assessment test. The degree of smoothness of the continuous approximations is determined by the bandwidth. Four bandwidth selection methods are currently...

Kernel Equating Under the Non-Equivalent Groups With Covariates Design.

Applied psychological measurement

Wiberg M, Bränberg K.
PMID: 29881012
Appl Psychol Meas. 2015 Jul;39(5):349-361. doi: 10.1177/0146621614567939. Epub 2015 Jan 20.

When equating two tests, the traditional approach is to use common test takers and/or common items. Here, the idea is to use variables correlated with the test scores (e.g., school grades and other test scores) as a substitute for...

Situational optimization function analysis: An ideal performance analysis inspired on Lewin's equation.

Psychological methods

Franco VR, Wiberg M, Laros JA.
PMID: 34410759
Psychol Methods. 2021 Aug 19; doi: 10.1037/met0000319. Epub 2021 Aug 19.

This study presents the situational optimization function analysis (SOFA) and has three aims. First, to develop a Bayesian implementation of SOFA. Second, to compare this implementation with three other maximum likelihood-based models in their accuracy to estimate true scores....

Psychometrics of three Swedish physical pediatric item banks from the Patient-Reported Outcomes Measurement Information System (PROMIS)®: pain interference, fatigue, and physical activity.

Journal of patient-reported outcomes

Carlberg Rindestig F, Wiberg M, Chaplin JE, Henje E, Dennhag I.
PMID: 34637029
J Patient Rep Outcomes. 2021 Oct 12;5(1):105. doi: 10.1186/s41687-021-00382-2.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS®) aims to provide self-reported item banks for several dimensions of physical, mental and social health. Here we investigate the psychometric properties of the Swedish pediatric versions of the Physical Health item...

Linking With External Covariates: Examining Accuracy by Anchor Type, Test Length, Ability Difference, and Sample Size.

Applied psychological measurement

Albano AD, Wiberg M.
PMID: 31551638
Appl Psychol Meas. 2019 Nov;43(8):597-610. doi: 10.1177/0146621618824855. Epub 2019 Feb 14.

Research has recently demonstrated the use of multiple anchor tests and external covariates to supplement or substitute for common anchor items when linking and equating with nonequivalent groups. This study examines the conditions under which external covariates improve linking...

Alternative Linear Item Response Theory Observed-Score Equating Methods.

Applied psychological measurement

Wiberg M.
PMID: 29881047
Appl Psychol Meas. 2016 May;40(3):180-199. doi: 10.1177/0146621615605089. Epub 2015 Sep 23.

Item response theory observed-score equating (IRTOSE) is widely used in many testing programs. The aim of this study was to empirically examine three alternative linear IRTOSE methods compared with the traditional IRTOSE method and to discuss these methods in...

A Note on the Poisson's Binomial Distribution in Item Response Theory.

Applied psychological measurement

González J, Wiberg M, von Davier AA.
PMID: 29881055
Appl Psychol Meas. 2016 Jun;40(4):302-310. doi: 10.1177/0146621616629380. Epub 2016 Feb 14.

The Poisson's binomial (PB) is the probability distribution of the number of successes in independent but not necessarily identically distributed binary trials. The independent non-identically distributed case emerges naturally in the field of item response theory, where answers to...

Gender equity in career and technical education.

Lufkin MaryE, Wiberg MaryM, Jenkins CourtneyReed, Berardi StefanieLLee, Boyer Terri, Eardley Ellen, Huss Janet.
UIID-AD: 2465
2007;421-443.

This chapter is limited to addressing career and technical education (CTE) programs from Grades 7-12 and two-year CTE associate of arts degree programs. Other programs related to gender equity in CTE are covered in greater depth elsewhere in this...
