Background/Context: Confirmatory factor analysis (CFA) model is a commonly adopted framework to estimate and test a measurement model. Once a well-fitting final CFA model is selected, the selected model may be used to test structural relationships of the latent constructs with other variables, to construct a test with desired reliability and…

Since 2018, colleagues from two research centers at Dublin City University have been collaborating to develop a measurement scale to assess individuals' ability to identify workplace bullying. Having agreed on an operational definition of the construct, an item pool of 26 workplace bullying scenarios, that is, short descriptions of…

This paper reports how I addressed the issue of extensive missing values in my PhD study, "Digital Competencies of High School Mathematics Teachers". I collected data using an online survey. Several methods exist to address the issue of missing values. I utilised multiple imputation (MI) as it provides more accurate results. The mean…

We revisit the merits of the retrospective pretest-posttest (RPP) design for repeated-measures research. The underutilized RPP method asks respondents to rate survey items twice during the same posttest measurement occasion from two specific frames of reference: "now" and "then." Individuals first report their current attitudes…

Lists six problems related to descriptive data and to factor analysis performed in a previous research study reported in this journal. Includes the authors' response to the suggested weaknesses of their study. (JN)

The author discusses a common error in marriage research, i.e. use of a control group. Single scores which are correlated require no randomized control group. Two arrays of scores which are correlated generally require a randomized control group. (Author/HMV)

Because the science of nursing is still at an early stage of development, nurses involved in clinical research often find that no appropriate measures are available to sample the theoretical construct of interest. Researchers often must design and test new instruments before proceeding to test theory. A study of the effect of nurse-client…

This manuscript is a report of the third revision of the Maryland Preschool Self-Concept of Scale originally developed by Smith (1977). Two samples of 4-, 5-, and 6-year old children (N = 54 and N = 78) were administered the Maryland Preschool Self-Concept Scale - Revised (MPSS-R). In the first study, the measure was given twice, 3 to 5 weeks…

Basically, two different forms of the sociometric technique for assessing children's peer status exist: peer-nomination and peer-rating. Although more popular, the peer-nomination technique has several psychometric deficiencies; these limit research efforts attempting to identify correlations between peer sociometric status and other social…

The question of how standardized tests can be better developed to improve educational program evaluation is probed in this paper. After the first section's brief introduction, section 2 explores the thesis that tests developed in terms of selection and inference may not serve current social functions of educational testing. To clarify this thesis,…

Efficient methods of using the Statistical Package for the Social Sciences (SPSS) to analyze National Assessment of Educational Progress (NAEP) data files are discussed. One error in the NAEP SPSS file is discussed, and another error (which may be system-dependent) is mentioned. In addition, purely mathematical methods are used to address the…

The Early Childhood Longitudinal Study-Kindergarten Class of 1998-99 (ECLS-K), selected a nationally representative sample of approximately 22,000 kindergartners in the fall of 1998 and is following these children through the end of the fifth grade. Baseline data about these children, their families, and their kindergarten programs were collected…
