Although much research has been done examining adult stressors, only recently have researchers focused attention on measuring levels of stress in children. Because children tend not to be aware of their own tense state, instruments are needed to measure levels of stress in children. The two main methods of measuring stress in children are to ask…

This procedures manual for the North Carolina Test Development Program details the tasks involved in test development. The basic steps are described in an introductory section; they are (1) to specify the institutional objectives of the curriculum and ensure their instructional validity; and (2) to specify the characteristics, such as the purpose…

Intended as a resource for individuals wishing to evaluate drug abuse education programs, this handbook, one of a series of seven, provides a collection of measuring devices that can improve the quality of such evaluations. Chapter 1 introduces the handbook's contents and outlines evaluation related issues specific to drug abuse education…

Intended as a resource for individuals wishing to evaluate diabetes education programs, this handbook, one of a series of seven, provides a collection of measuring devices that can improve the quality of such evaluations. Chapter 1 introduces the handbook's contents and outlines evaluation related issues specific to diabetes education programs.…

The validity of the Personality Diagnostic Questionnaire-Revised (PDQ-R) was examined. The PDQ-R and the Crowne-Marlowe Social Desirability Scale (SD) were administered in the spring of 1989 to 45 undergraduates (26 females and 19 males) at Gettysburg College in Pennsylvania. One month later, the Hopkins Symptom Check List (SCL-90) was…

This paper discusses cognitive and noncognitive variables, and their relationship with each other, in learning and in educational evaluation. The nature of noncognitive learning environment variables is examined. The following instruments that have been widely used in assessing classroom environment are described: (1) the Learning Environment…

In latent trait theory the latent space, or space of the hypothetical construct, is usually represented by some unidimensional or multi-dimensional continuum of real numbers. Like the latent space, the item response can either be treated as a discrete variable or as a continuous variable. Latent trait theory relates the item response to the latent…

The nonparametric approach to test theory discussed here has its roots in the early work of Guttman, Lazarsfeld, and Meredith; and more recently in the work of Cliff and in Tatsuoka and Tatsuoka. Mokken's extensive treatment of this subject concentrated on defining, constructing, and testing unidimensional scales, based on responses to dichotomous…

This paper provides an up-to-date review of the relationship between item response theory (IRT) and (nonlinear) common factor theory and draws out of this relationship some implications for current and future research in IRT. Nonlinear common factor analysis yields a natural embodiment of the weak principle of local independence in appropriate…

In connection with the development of item pools for the Navy's experimental Computerized Adaptive Testing (CAT) system, items in five different content areas (General Science, Paragraph Composition, Word Knowledge, Math Knowledge, and Arithmetic Reasoning) have been calibrated using item response theory (IRT) methodology. Operational Armed…

Psychometric properties of the Alcohol Behavior, Attitude, and Awareness Inventory (ABAA Inventory) were assessed using data collected in 1987 from 799 university students. Results suggested that the ABAA Inventory was internally-consistent (alpha = .82) and stable over time (test-retest coefficient = .77). Subscale alphas ranged from .45 to .92,…

The Developmental Inventory of Sources of Stress (DISS) is an instructional tool designed to assist counselors, advisors, and faculty in reducing stress among college students (specifically, high risk college freshmen, although it can be utilized effectively with any college student population). The instrument focuses on sources of stress over…

In this study 6,942 items from two standardized achievement test batteries--the Stanford (Early School Achievement Battery, Achievement Battery, and Test of Academic Skills) and the Comprehensive Test of Basic Skills--were analyzed. Focus was on determining: (1) the extent to which these test batteries included general cognitive operations (GCOs)…

The feasibility of using item response theory (IRT) as a psychometric model for the Graduate Record Examination (GRE) Aptitude Test was addressed by assessing the reasonableness of the assumptions of item response theory for GRE item types and examinee populations. Items from four forms and four administrations of the GRE Aptitude Test were…

A formal analysis is presented of the effects of item deletion on equating/scaling functions and reported score distributions. The phrase "item deletion" refers to the process of changing the original key of a flawed item to either all options correct, including omits, or to no options correct, i.e., not scoring the flawed item. There…
