Exploratory factor analysis in validation studies
BACKGROUND: The Exploratory Factor Analysis (EFA) procedure is one of the most commonly used in social and behavioral sciences. However, it is also one of the most criticized due to the poor management researchers usually display. The main goal is to examine the relationship between practices usually considered more appropriate and actual decisions made by researchers. METHOD: The use of exploratory factor analysis is examined in 117 papers publi…
Psychometric and Psychological Effects of Item Selection and Review on Computerized Testing
Psychometric properties of computerized testing, together with anxiety and comfort of examinees, are investigated in relation to item selection routine and the opportunity for response review. Two different hypotheses involving examinee anxiety were used to design test properties: perceived control and perceived performance. The study involved three types of administration of a computerized English test for Spanish speakers (adaptive, easy adapti…
An Investigation of Self-Adapted Testing in a Spanish High School Population
This study, using Spanish high school students, compared four types of a computer-based English vocabulary test: (a) a self-adapted test (SAT), (b) a computerized adaptive test (CAT), (c) a conventional test of randomly selected items, and (d) a test that combined SAT and CAT (SCAT). No statistically significant differences were found among the test types for either estimated ability or posttest anxiety. Statistically significant differences were…
Adtest
This article describes an easy-to-use program for computer-adaptive testing. Two files have to be provided to use the program: the bank of items and the file containing their parameters. The program has been checked by simulation. Data on the accuracy of ability estimation are offered. Details on how to run the program and the format of both required files are also provided
