Examined relationships between parent and teacher and between mother and father Social Skills Rating System (SSRS) reports for 134 urban Head Start children to assess the cross-informant capacity of the SSRS. Found an insignificant relationship between parent and teacher SSRS ratings; found significant congruence between mothers' and fathers'…

Examined the stability of the standard error of measurement and the relationship between the reliability coefficient and the variance of both true scores and error scores for 170 school districts in a state. As expected, reliability coefficients varied as a function of group variability, but the variation in split-half coefficients from school to…

Presents an Item Response Theory (IRT) method for estimating standard errors of measurement of scale scores for the situation in which scale scores are nonlinear transformations of number-correct scores. Also describes procedures for estimating the average conditional standard error of measurement for scale scores and the reliability of scale…

Studied the stability of test anxiety over time by examining the level of reported cognitive test anxiety at three points in an academic semester. Results for 64 undergraduates show that it is practical to collect test anxiety data at times other than when a test is being completed. It does not seem necessary to collect test anxiety data prior to…

Counselors conducting survey research have many item format options to contemplate. This study examined midpoint selection and the effect on reliability of including or excluding midpoint options, and using both positively and negatively worded items. Findings indicate that reliability can be affected by both midpoint options and reverse coding.…

Although often ignored, reliability is critical when interpreting study effects and test results. Accordingly, this article focuses on the most commonly used estimate of reliability, internal consistency coefficients, with emphasis on coefficient alpha. An interpretive framework is provided for applied researchers and others seeking a conceptual…

Reliability and validity of Chinese Self-Report Family Inventory (C-SFI) were examined in three studies. Study 1 showed C-SFI was temporally stable and internally consistent. Study 2 indicated C-SFI could discriminate between clinical and nonclinical groups. Study 3 gave support for internal consistency, concurrent validity and construct validity.…

Applied a procedure to assess measurement invariance across cultures developed by J. Steenkamp and H. Baumgartner (1998) to a scale to measure cognitive age using data collected in India (n=195), China (n=250), and Korea (n=251). Results from confirmatory factor analyses indicate that the technique provides a valuable tool to assess measurement…

Illustrates a number of ways in which confidence intervals for reliability coefficients can be estimated. Suggests that authors who submit articles to "Educational and Psychological Measurement" report confidence intervals for reliability estimates whenever they report score reliabilities and that they note the interval estimation…

A sample of 293 local district assessments used in the Nebraska STARS (School-based Teacher-led Assessment and Reporting System), 147 from 2004 district mathematics assessment portfolios and 146 from 2003 reading assessment portfolios, was scored with a rubric evaluating their quality. Scorers were Nebraska educators with background and training…

A linear combination of a set of measures is often sought as an overall score summarizing subject performance. The weights in this composite can be selected to maximize its reliability or to maximize its validity, and the optimal choice of weights is in general not the same for these two optimality criteria. We explore several relationships…

Responses of 871 adults to the Adult Manifest Anxiety Scale-Adult version (AMAS-A) were factor analyzed using the method of principal axis factoring with promax rotation. Factor analysis yielded a four-factor solution: three anxiety factors (Worry/Oversensitivity, Stress, and Physiological Anxiety) and a Lie factor. The AMAS-A's three-factor…

In the present study we have investigated the acquisition of the past participle of Italian verbs of the second (including mostly irregular verbs) and third (including mostly regular verbs) conjugations in school age children, and with simulations with an artificial neural network. We aimed to verify the extent to which children are sensitive to…

This article is the third contribution to a research methods series dedicated to getting good results from survey research. In this series, "good results" is a stenographic term used to define surveys that yield accurate and meaningful information that decision makers can use with confidence when conducting program evaluation and policy assessment…

Emotional availability (EA) is a prominent index of socioemotional adaptation in the parent-child dyad. Is EA affected by context? In this methodological study, 34 mothers and their 2-year-olds were observed in 2 different settings (home vs. laboratory) 1 week apart. Significant cross-context reliability and continuity in EA as measured with the…
