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)

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)

The Westside Test Anxiety Scale is a brief, ten item instrument designed to identify students with anxiety impairments who could benefit from an anxiety-reduction intervention. The scale items cover self-assessed anxiety impairment and cognitions which can impair performance. Correlations between anxiety-reduction as measured by the scale and…

This study investigated the validity and reliability of the Turkish version of the Metacognitive Awareness Inventory. The sample of the study consisted of 607 university students. Results of language equivalence indicated that the correlations between Turkish and English forms of the MAI were quite high (r = 0.93). As a result of a series of…

Although clinical observations suggest that health-related anxiety is present, to some extent, in a number of anxiety disorders, this relationship has not been examined empirically. The present study therefore utilized the Short Health Anxiety Inventory (SHAI) to elucidate the structure of such symptoms among patients with anxiety disorders and to…

This dissertation reports development and validation studies of a Web-based standardized test of Japanese as a foreign language (JFL), designed to measure learners' off-line grammatical and pragmatic knowledge in multiple-choice format. Targeting Japanese majors in the U.S. universities and colleges, the test is designed to explore possible…

Depression at the end of life is a common mental health issue with serious implications for quality of life and decision making. This study investigated the reliability and validity of one of the most frequently used measures of depression, the Hamilton Depression Rating Scale (HAM-D) in 422 patients with terminal cancer admitted to a palliative…

This study reports on the validation of a scale to assess adolescent girls' frequency of sexual communication with their parents. The Parent-Adolescent Communication Scale (PACS) was administered to 522 African American female adolescents ranging in age from 14 to 18. The PACS demonstrated satisfactory internal consistency (across multiple…

The Childhood Asperger Syndrome Test (CAST) is a 37-item parental self-completion questionnaire designed to screen for high-functioning autism spectrum conditions in epidemiological research. The CAST has previously demonstrated good accuracy for use as a screening test, with high sensitivity in studies with primary school aged children in…

The reliability of the Student-Life Stress Inventory of B. M. Gadzella (1991) was studied. The inventory consists of 51 items listed in 9 sections indicating different types of stressors (frustrations, conflicts, pressures, changes, and self-imposed stressors) and reactions to the stressors (physiological, emotional, behavioral, and cognitive) as…

The present paper reviews the techniques commonly used to correct an observed correlation coefficient for the simultaneous influence of attenuation and range restriction effects. It is noted that the procedure which is currently in use may be somewhat biased because it treats range restriction and attenuation as independent restrictive influences.…

Two indices of profile reliability are shown to be equivalent in terms of the individual independent canonical composites; however, because of different weighting procedures, they yield different overall indices of profile reliability. A common formula is provided from which both indices can be derived. (Author)

The S.I.T. is an age scale of intelligence with demonstrated reliability and high validity coefficients correlated to the Stanford-Binet. The items of the SIT were classified according to a scheme resembling Valett's classification of Stanford-Binet test items. A comparison of the classifications is made. (Author)

Extrapolated IQs for the Wechsler Intelligence Scale for Children-Revised (WISC-R) are presented for sums of scaled scores that are both below and above the values published in Wechsler's WISC-R manual. The regression equations on which these extrapolations are based and cautions regarding the clinical use of these IQs are also presented. (Author)

The use of the intraclass correlation in determining reliability is discussed and shown to be both appropriate and simple to use in the case of an observational measure, provided that observations are made on at least two occasions. The interpretation of such coefficients is explained in terms of generalizability theory, and real data are used to…
