A Revised Version of the Norwegian Adaptation of the Test Anxiety Inventory in a Heterogeneous Population
Peer reviewed Peer reviewed
Direct linkDirect link
Oktedalen, Tuva; Hagtvet, Knut A. – Scandinavian Journal of Educational Research, 2011
Confirmatory factor analysis and Multiple Indicators, Multiple Causes (MIMIC) modeling were employed to investigate psychometric properties of a revised adaptation of the Norwegian version of the Test Anxiety Inventory (RTAIN) in a sample of 456 students. The study supported the Norwegian version as a useful inventory for measuring the components…

A Two-Facet Measurement Methodology for Assessing Item Parcels: An Application to Measuring Political Knowledge in Secondary School
Peer reviewed Peer reviewed
Direct linkDirect link
Hagtvet, Knut A.; Solhaug, Trond – Scandinavian Journal of Educational Research, 2005
Recent literature on parcel indicators in measurement models used in covariance structural modelling has mainly been concerned with statistical properties of parameter estimates. Less attention has been paid to measurement properties for inferring the assumed latent construct. The present study illustrates a two-facet measurement model that…

Conceptual and Empirical Components of an Internal Domain Study: An Illustration in Terms of the Achievement Motives Scale.
Peer reviewed Peer reviewed
Hagtvet, Knut A.; Zuo, Li – Scandinavian Journal of Educational Research, 2000
Used the domain sampling model of generalizability theory to study ways of improving a construct measure, the Achievement Motives Scale (AMS) (R. Nygard and T. Gjesme, 1973). AMS results for 504 Chinese high school students and 252 U.S. graduate students are the basis for suggestions to improve the two language versions' approximations to the…

Assessment of Latent Constructs: A Joint Application of Generalizability Theory and Covariance Modelling with an Emphasis on Inference and Structure.
Peer reviewed Peer reviewed
Hagtvet, Knut A. – Scandinavian Journal of Educational Research, 1998
Demonstrates how perspectives from covariance structural modeling and generalizability theory can be combined for a comprehensive assessment of latent constructs. This approach to examining variance components is illustrated by one- and two- facet designs, and can be extended to more complex designs. (MAK)

The Discriminant Predictive Validity of the Reynell Developmental Language Scales.
Peer reviewed Peer reviewed
Hagtvet, Knut A.; Hagtvet, Bente E. – Scandinavian Journal of Educational Research, 1990
The discriminant validity of two subscales of the Reynell Developmental Language Scales (RDLS) was investigated using data from 225 children given the RDLS at age 4 and the Illinois Test of Psycholinguistic Abilities at age 5. Results support the hypothesis; the RDLS scales measure distinct but correlated language abilities. (SLD)
