Use of portfolios and performance tasks has exponentially increased as educators seek to be as "fair" as possible, and to link measurement, assessment, and evaluation more closely to cognition, curriculum, and instruction. However, high standards of reliability and validity are equally essential in the use of "authentic"…

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…

Effects of item wording on questionnaire reliability and validity were studied, using 280 undergraduate business students who completed a questionnaire comprising 4 item types: (1) regular; (2) polar opposite; (3) negated polar opposite; and (4) negated regular. Implications of results favoring regular and negated regular items are discussed. (SLD)

An approach is presented to the definition of minimal competence for judges to use in standard setting. Panelists in standard setting must receive training to ensure that differences in rating result from differences in perceptions of item difficulty, not in differences of opinion about the definition of minimal competence. (SLD)

The reliability and validity of the Working with Young Children and Their Families instrument were tested with 101 of 192 occupational therapists surveyed. The form proved to be a reliable way of measuring the outcome of workshops to improve therapists' competence in working with families of children with special needs. (SK)

The Children's Sex Role Inventory was tested on third, fourth, sixth, and seventh graders. Reliability was established through internal consistency of femininity and masculinity scales and stable test-retest reliabilities. Validity of the scales was evident in gender differences on both scales. (BC)

The construct validity of hypothesized survey items and data reduction procedures for selected psychosocial constructs frequently used in breast cancer screening research were investigated in telephone interviews with randomly selected samples of 1,184 and 903 women and a sample of 169 Hispanic clinic clients. Validity of the constructs is…

The degree to which reliability affects the power of analysis of variance (ANOVA) tests involving one factor with two and three samples was quantified and tabulated by taking into account sample size, level of significance, and true score effect size. Results confirm a substantial effect on power. (SLD)

Comparison of scores from a normative sample of 880 children and 276 sexually abused children on the Child Sexual Behavior Inventory (CSBI), a checklist for 2- through 12-year-old children, supports the reliability and validity of the instrument. The CSBI is directly related to specific features of sexual abuse. (SLD)

This paper discusses the role of transition in school reform and methodology for developing a Florida database on transition-related programs. It describes procedures for ensuring the validity and reliability of database information sources. Findings from the data collection process, concerning common program terminology and school district size…

Structural equation models of the same construct collected on different occasions are evaluated in 2 studies involving the evaluation of 157 college instructors over 8 years and data for over 2,200 high school students over 4 years for the Youth in Transition Study. Results challenge overreliance on simplex models. (SLD)

The reliability and validity of the revised California Psychological Inventory's (CPI) Vector 1 scale, a measure of introversion and extraversion, were studied with 345 college students (109 males and 236 females). Results support the scale as a valid measure of the introversion-extraversion construct of H. G. Gough. (SLD)

Data from 6,472 South Carolina residents aged over 55 years support the reliability of S. Katz's Activities of Daily Living scale when data are collected by self-report telephone interview. Results indicate that telephone interview methods are a fast, inexpensive, and safe way to collect data for research and policy formation. (SLD)

The way in which trait and rater variance combine in multitrait-multirater (MTMR) performance appraisal data is explored. Implications of the confirmatory factor analytic model and the composite direct product (CDP) model for MTMR data are examined. Superior fit of the CDP model for four data sets is discussed. (SLD)

The applicability of the Children's Depression Inventory (CDI) (in the informant-rating version) to mentally retarded adults was evaluated with 798 individuals. Evaluation of internal consistency, interrater reliability, factor analysis, and effects of age, sex, and degree of mental retardation indicated that the CDI is suitable as a diagnostic…
