Reliability and validity of self-reported behavior within a deviant population are examined using data from 2 interviews with 323 narcotics addicts conducted 10 years apart (1974-75 and 1985-86). Results complement existing reliability and validity studies of alcohol use, and suggest that quality information can be obtained from heroin users. (SLD)

A 1990 study of domain-referenced scores from a multiple-station clinical examination for foreign medical graduates investigated identification of essential checklist items, setting of minimum passing scores, consistency of candidate classification, and perceived appropriateness of the number of candidates classified as competent. Results and…

Logical difficulties with existing measures of construct implications are examined, and a new instrument that partially overcomes them--the Logical Relations Grid--is described. Empirical data from a study of 28 children and 47 parents in Australia are given in support of instrument reliability and validity. (SLD)

This rejoinder to Grant Wiggins on performance assessment suggests that true educational reform will undoubtedly be evidenced by something more substantial than pocket folders bulging with student work. Labeling performance tests "authentic" does not ensure their validity, reliability, or incorruptibility. Such tests are neither replacements nor…

The performance of foreign medical school graduates on multistation standardized patient-based tests was used to determine the validity and generalizability of global ratings of their clinical competence made by expert examiners. Results suggest that these ratings can be used as an effective form of assessment in this context. (Author/MSE)

The Walker/Severson Systematic Screening for Behavior Disorders measure was revised for use with preschool children. The revision consists of three hierarchical stages of increasingly time-consuming methodologies: (1) teacher rankings, (2) teacher ratings, and (3) direct behavioral observations. Testing with 121 children demonstrated significant…

Evaluation of the Child Dissociative Checklist found it to be a reliable and valid observer report measure of dissociation in children, including sexually abused girls and children with dissociative disorder and with multiple personality disorder. The checklist, which is appended, is intended as a clinical screening instrument and research measure…

Portfolio assessment can be a valuable tool in assessing professional proficiency in teachers if appropriate attention is given to issues of reliability and validity. The Teaching Assessment Project at Stanford University has explored portfolios as an alternative to traditional methods of teacher evaluation. (IAH)

A network-flow model is formulated for constructing parallel tests based on classical test theory while using test reliability as the criterion. Practitioners can specify a test-difficulty distribution for values of item difficulties as well as test-composition requirements. An empirical study illustrates the reliability of generated tests. (SLD)

Some of the methods originally used to find relationships between reliability and power associated with a single measurement are extended to difference scores. Results, based on explicit power calculations, show that augmenting the reliability of measurement by reducing error score variance can make significance tests of difference more powerful.…

Two articles discuss the controversy about the relationship between reliability and the power of significance tests in response to the discussion of Donald W. Zimmerman, Richard H. Williams, and Bruno D. Zumbo. Lloyd G. Humphreys emphasizes the differences between what statisticians can do and constraints on researchers. Zimmerman, Williams, and…

Measurement and psychometric quality of the Sternberg task (S. Sternberg, 1966, 1969), a memory search task, was investigated with 78 undergraduates. Individual performance was fairly homogeneous across responses, fairly unstable over time, and fairly stable across stimulus content. Implications for individual differences research are discussed.…

A study tested the validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) for determining the presence of mania (bipolar disorder) in 22 individuals with severe mental retardation. Results found the mania subscale to be internally consistent and able to be used to classify manic and control subjects accurately. (Author/CR)

Provides psychometric information on the second edition of the Beck Depression Inventory (BDI-II) (A. Beck, R. Steer, and G. Brown, 1996) for internal consistency, factorial validity, and gender differences. Results indicate that the BDI-II is a stronger instrument than its predecessor in terms of factor structure. (SLD)

Hearing in Noise Test (HINT) list equivalency was examined using 24 listeners (ages 60 to 70) with sensorineural hearing impairments. Four speech conditions were tested, including a quiet condition and three noise conditions. Results found that for the three noise conditions, all lists were within 2dB of the means, indicating list equivalency.…
