Understanding the cognitive processes, skills and strategies that examinees use in testing is important for construct validity and score interpretability. Although response processes evidence has long been included as an important aspect of validity (i.e., "Standards for Educational and Psychological Tests," 1999), relevant studies are…

In order to reach valid and reliable test scores, various test theories have been developed, and one of them is nonparametric item response theory (NIRT). Mokken Models are the most widely known NIRT models which are useful for small samples and short tests. Mokken Package is useful for Mokken Scale Analysis. An important issue about validity is…

Developed a scale for detecting random responses on the Multidimensional Pain Inventory using 95 undergraduates, 34 chronic pain patients, and 115 health-care professionals. A variable response scale was developed that discriminated accurately between valid and random profiles in two cross-validation samples, predicting random profiles with 90%…

Previous knowledge of the difficulty index and the intercorrelations of the items will allow group results to be predicted and manipulated. A compound bionomial probability function of a testscore is established for which a computer program has been written. Three item selections and the appropriate probability distributions are given which give…

The Marlowe-Crowne Social Desirability Scale (MCSDS), the most commonly used social desirability bias (SDB) assessment, conceptualizes SDB as an individual's need for approval. The Balanced Inventory of Desirable Responding (BIDR) measures SDB as two separate constructs: impression management and self-deception. Scores on SDB scales are commonly…

Reliable Digit Span (RDS) is an indicator used to assess the validity of cognitive test performance. Scores of 7 or lower suggest poor effort or negative response bias. The possibility that RDS scores are also affected by pain has not been addressed thus potentially threatening RDS specificity. The current study used cold pressor-induced pain to…

The development of a series of parallel single-topic tests for testing attainment of 14 objectives concerned with inquiry skill in biology is discussed. The series of eight two-part tests are called "Explorations in Biology" (EIB). (CK)

The extent of inaccuracy in student coding of race on Scholastic Aptitude Test (SAT) forms and the effect of inaccurate coding and non-coding on results for the Montgomery County (Maryland) Public Schools are assessed. The County maintains a database that includes each student's race as designated by the student's parent on the school registration…

Appropriateness indexes (statistical formulas) for detecting suspiciously high or low scores on aptitude tests were presented, based on a simulation of the Scholastic Aptitude Test (SAT) with 3,000 simulated scores--2,800 normal and 200 suspicious. The traditional index--marginal probability--uses a model for the normal examinee's test-taking…
