D.V. Budescu and J.L. Rogers (1981) proposed a method of adjusting correlations of scales to eliminate spurious components resulting from the overlapping of scales. Three reliability correction formulas are derived in this article that are based on more tenable assumptions. (SLD)

Developed Personal Independence Profile (PIP) as an instrument to measure aspects of independence beyond physical and cognitive functioning in people with diverse disabilities. PIP was tested for reliability and validity with 185 subjects from 10 independent living centers. Findings suggest that the Personal Independence Profile measures the…

This article describes the Scale for the Evaluation of Gifted Identification Instruments, developed for use by school decision makers. Development of the scale is reviewed in terms of five areas of assessment: validity, reliability, propriety, respondent appropriateness, and utility. Specific guidelines and cautions in using the scale are also…

Examined the validity of the Adult Attachment Interview (AAI) measure by interviewing 83 mothers twice over 2 months, using different interviewers on each occasion. The results indicated that the reliability of the AAI classifications was quite high over time and across interviewers. The AAI classifications were independent of nonattachment…

Reviews commercially available instruments to assess students' study skills/habits/behavior, finding that none completely meets the standards set by the American Psychological Association or the American Educational Research Association. Offers guidance on selecting and applying these instruments in college settings. (DMM)

Outlines and discusses the nature and assumptions of the Willingness to Communicate scale. Discusses data relating to the reliability and validity of the instrument. Concludes that the scale is of sufficient quality to be recommended for research and screening purposes. (SR)

Analyses of the internal consistency of three autism scales--the Autism Behavior Checklist (ABC), the Real Life Rating Scale (RLRS), and the Childhood Autism Rating Scale (CARS)--were conducted with 34 children with pervasive developmental disabilities. Good internal consistency was found for the CARS. Adequate full-scale consistency was found for…

Coefficient alpha was examined through computer simulation as an estimate of test reliability under violation of two assumptions. Coefficient alpha underestimated reliability under violation of the assumption of essential tau-equivalence of subtest scores and overestimated it under violation of the assumption of uncorrelated subtest error scores.…

When using assessment instruments for personnel purposes, identify the purposes of assessment, specify criteria for excellent performance, determine behavior standards, and select appropriate methodology. Correlation analysis is a useful technique for establishing the validity of an instrument. (SK)

Investigation of the stability of Wechsler Adult Intelligence Scale Revised scores of 25 college students over a 4-year period found that global and subtest scores were highly stable. Subtest scores tended to be higher on the retest, but global scores were not despite four years of educational experiences between test administrations. (Author/DB)

Tested Bugen's Coping with Death Scale. Individuals who had written wills, planned estates and funerals, and signed organ donor cards scored higher on the Coping with Death Scale. Because Coping with Death scores were more consistently different in those who prepared for death, this scale may help in efforts to predict those who will engage in…

Studies in five senior medical school classes at Southern Illinois University investigated whether using multiple standardized patients to simulate the same case in postclerkship medical student evaluation affects the measure's reliability. Results of three studies show little or no effect on reliability of total, checklist, or written test…

Created College Classroom Environment Scales (CCES), instrument with six subscales (Cathectic Learning Climate, Professorial Concern, Inimical Ambiance, Academic Rigor, Affiliation, and Structure) to assess social climate of college classrooms. Findings from four studies estimating CCES' reliability and validity suggest it is sufficiently reliable…

Twenty-one language tests that included norms for children ages 4 and 5 were reviewed for information on 10 psychometric criteria. Administration of the 4 tests meeting the most criteria to 20 preschool children with specific language impairments and 20 controls found that only 1 (the Structured Photographic Expressive Language Test) provided…

Developed and validated Job Satisfaction Scale (JSS) in series of studies from 1980 to 1991 involving over 600 helping professionals. Across administrations, alpha reliabilities ranged between 0.83 and 0.91, and reliabilities of intrinsic and organizational satisfaction subscales ranged from 0.85 to 0.90 and 0.78 to 0.90, respectively.
