Alsawalmeh, Yousef M.; Feldt, Leonard S. – Educational and Psychological Measurement, 1999
Develops a statistical test for the hypothesis that alpha'(1) =alpha'(2) when alpha'(1) is the Spearman-Brown extrapolated value of Cronbach's alpha reliability for test 1 and alpha'(2) is the unadjusted coefficient for test 2. The test is shown to exercise tight control of Type I error. (Author/SLD)

Kromrey, Jeffrey D.; Foster-Johnson, Lynn – Educational and Psychological Measurement, 1999
Shows that the procedure recommended by D. Lubinski and L. Humphreys (1990) for differentiating between moderated and nonlinear regression models evidences statistical problems characteristic of stepwise procedures. Interprets Monte Carlo results in terms of the researchers' need to differentiate between exploratory and confirmatory aspects of…

Sturman, Michael C. – Educational and Psychological Measurement, 1999
Compares eight models for analyzing count data through simulation in the context of prediction of absenteeism to indicate the extent to which each model produces false positives. Results suggest that ordinary least-squares regression does not produce more false positives than expected by chance. The Tobit and Poisson models do yield too many false…

Lee, Frances Laimui; Yeung, Alexander Seeshing – Educational and Psychological Measurement, 1999
Examined the factor structure of the responses of 487 Chinese high school students to the Verbal, Math, Academic, and General self-concept scales of the Self-Description Questionnaire-II administered in China at two time points. Results support the multidimensionality and domain specificity of academic self-concepts found in Western countries for…

Forsterlee, Robert; Ho, Robert – Educational and Psychological Measurement, 1999
Studied the factor structure of the Need for Cognition Scale (NFC) (J. Cohen, E. Scotland, and D. Wolfe, 1955) (short form) with samples of 510 and 697 Australian adults. Results support the use of the short version of the NFC with Australian samples. (SLD)

Davis, Cindy; Tang, Catherine So-Kum; Chan, Shui-Fun Fiona; Noel, Beth – Educational and Psychological Measurement, 1999
Developed and standardized an Acquired Immune Deficiency Syndrome (AIDS) questionnaire which was tested with 1,667 adolescents and 277 college students in Hong Kong. Results support the reliability and validity of the scores from this measure of AIDS knowledge among adolescents in Hong Kong. (SLD)

Kulinna, Pamela Hodges; Silverman, Stephen – Educational and Psychological Measurement, 1999
Developed an instrument to examine teachers' attitudes toward teaching physical activity and fitness. Tested the instrument in a content-validity study with 29 experts and a reliability and validity study involving 253 teachers. Results support the use of the instrument. (SLD)

Li, Mao-Neng Fred; Lautenschlager, Gary J. – Educational and Psychological Measurement, 1999
Describes a Statistical Analysis System (SAS) MACRO for computing various indices of interrater agreement, including a new generalizability coefficient, for categorical data in a single-facet, crossed design. (Author/SLD)

Jackson, Dennis L.; Teal, Cayla R.; Raines, Susan J.; Nansel, Tonja R.; Burdsal, Charles S.; Force, Ronald C. – Educational and Psychological Measurement, 1999
Used confirmatory factor analysis to assess the fit of the original solution of the Student's Perception of Teaching Effectiveness questionnaire (C. Burdsal and J. Bardo, 1986) to a sample of more than 7,000 university classes. Analyses provide a clear interpretation of six first-order and two second-order dimensions of instructional quality. (SLD)

Pomplun, Mark; Capps, Lee – Educational and Psychological Measurement, 1999
Studied gender differences in answers to constructed-response mathematics items on approximately 500 papers from grades 7 and 10 from the Kansas Assessment Program. Rubric-relevant variables were highly predictive of holistic scores and accounted for some of the gender differences, especially in grade 7. (SLD)

Ludlow, Larry H.; O'Leary, Michael – Educational and Psychological Measurement, 1999
Focuses on the practical effects of using different statistical treatments with omitted and not-reached items in an item-response theory application. The strategy selected for scoring such items has considerable impact on the interpretation of results for individual or group-level assessments. (Author/SLD)

Tate, Richard; Heidorn, Mark – Educational and Psychological Measurement, 1999
Estimated year-to-year changes in average writing performance for 188 schools using a group-level version of the generalized partial credit item-response theory model. Results illustrate that technical equating adjustments can be important even when there have been rigorous efforts to make prompts and rating training equivalent to the old tests.…

Liukkonen, Jarmo; Leskinen, Esko – Educational and Psychological Measurement, 1999
Analyzed the reliability and validity of scores of 557 14-year-old Finnish male soccer players on the children's version of the Perception of Success Questionnaire (G. Roberts and others, 1998). Internal consistency coefficients for the two subscales' scores were high, and scores on both scales had strong construct validity. (LSD)

Raaijmakers, Quinten A. W. – Educational and Psychological Measurement, 1999
Introduces relative mean substitution as an approach to the substitution of missing values in surveys with Likert-type scales. Compares the approach to three other methods for dealing with missing data for samples of 1,674, 400, and 100. Results indicate that the relative mean substitution approach produces the most accurate estimates. (SLD)
