Analysis of spontaneous language samples of 10 children (ages 8-9) with specific language impairments found that interviews were a reliable, valid, and efficient assessment context, eliciting the same profile of behaviors as a freeplay context without altering diagnostic classifications. (Author/JDD)

Results from a survey of 62 students (ages 8-13) with mild mental retardation and 62 students without retardation indicated that high percentages of both groups understood what loneliness means; a loneliness questionnaire yielded satisfactory internal reliability; and boys but not girls with mental retardation reported more loneliness than did…

Forty prototypical descriptions representing 4 aptitude domains and 4 talent fields were rated by 2,343 intermediate-level pupils and their teachers, and indices of interpeer agreement were computed. A majority of the prototypes maintained acceptable interpeer agreement levels. Interpeer agreement depended primarily on the specific aptitude or…

A measurement and psychometric examination of cognitive tasks was carried out with 195 undergraduates, investigating stability of latencies and number correct scores over a 2-week period and relations with standardized test and ability measure scores. Results are discussed in terms of the need for evaluating cognitive task measurement properties.…

Describes the development of a measure of self-perceived abilities to implement various health promoting behaviors, reporting on a study of the psychometric properties of the measure in three samples. Results suggest the measure demonstrates adequate reliability and demonstrates predicted relationships with other health measures. (SM)

A study compared the accuracy of experienced staff with a learning test in predicting the ability of 18 persons with mental retardation to learn 12 training tasks. Results found the Assessment of Basic Learning Abilities test was more accurate for predicting client performance than the assessments of experienced staff. (Author/CR)

Twenty-four studies involving functional assessment of students with emotional and behavioral disorders (E/BD) or those at risk for E/BD are reviewed in three main areas: (1) characteristics of participants; (2) types of functional assessment procedures and instruments employed; and (3) the reliability and validity of these instruments and…

Using videos of physiotherapy students, compared two assessment forms for validity and reliability (the first currently used by an academic program and the second developed from practitioners' perceptions of competence). Also investigated effects of training on assessment decisions. Found wide differences in individual ability to assess students…

The reliability and construct validity of ratings for the Autism Behavior Checklist were examined with a sample of 198 children diagnosed with autistic disorder and conditions often confused with autism. Alpha coefficients for the five scales of the ABC as well as the Total Score were reported and the factor structure of the ABC was examined…

As item response theory (IRT) becomes popular in educational and psychological testing, there is a need of reporting IRT-based effect size measures. In this study, we show how the standardized mean difference can be generalized into such a measure. A disattenuation procedure based on the IRT test reliability is proposed to correct the attenuation…

Intraindividual variability in positive and negative affect was assessed by the positive affect (Contentment, Joy, Vigor, Love, and Excitement) and negative affect (Depression, Hostility, Anxiety, Agitation, and Social Anxiety) subscales of the state version of the Comprehensive Personality and Affect Scales (COPAS) during a 3-week period. Using…

For a number of years, the dominant approach to measuring individual differences in how people respond to interpersonal conflict has been the dual-concerns model, which assesses five broad conflict styles said to result from one's standing on two underlying dimensions: concern for self and concern for other. This article describes the development…

Two aspects of the reliability of multidimensional measures can be distinguished: the amount of scale score variance that is accounted for by all underlying factors (composite reliability) and the degree to which the scale score reflects one particular factor (construct reliability). Confidence intervals for composite and construct reliabilities…

The authors describe a potential disconnect between research and practice in literacy assessment and instruction. They organize discussion around professionally recognized standards for the evaluation of educational assessments and assessment practices. These standards address both technical aspects of tests (e.g., validity; reliability;…

The Beck Depression Inventory-II (BDI-II; A. T. Beck, R. A. Steer, & G. K. Brown, 1996) is a widely used measure of depressive symptomatology originally authored in English and then translated to Spanish. However, there are very limited data available on the Spanish translation. This study compared the psychometric characteristics of the…
