A consistent picture regarding the reliability of the McCarthy Scales of Children's Abilities cannot be obtained from current literature. A clear understanding of the stability of the MSCA would be particularly useful in establishing and planning academic programs and this research attempts to provide such an estimate of reliability.

In a sample of 380 children, self-esteem as measured by the Coopersmith Self-Esteem Inventory became more stable and more highly correlated with school achievement as the children grew older. Children's self-perceptions appear less firmly established, and therefore may be more responsive to intervention, at earlier ages. (Author)

Joreskog's procedure for the analysis of simplex models was used to test Humphreys' assertion that eight semesters of undergraduate grade point averages have a simplex form. The assertion was confirmed, and precise estimates of unattenuated correlations and reliabilities were also obtained. (Author/JKS)

Research is presented on the construction of job families based on Position Analysis Questionnaire data. The data were subjected to a component analysis. Results were interpreted as sufficiently encouraging to proceed with analyses of validity generalization within the job families. (Editor/RK)

The Career Maturity Inventory Attitude Scale materials were found to provide very little useful information concerning the instrument's reliability. The data that were interpretable showed the scale to have quite modest reliability. (Author)

Results of a study to determine whether paired-comparisons i intransitivity is a function of intransitivity associated with specific stimulus objects rather than a function of the entire set of stimulus objects suggested that paired-comparisons intransitivity relates to individual differences variables associated with the respondent. (Author/CTM)

A new formula for the correction for chance success due to guessing was advanced and investigated, the mathematical solution of which has the property of equating the scores of fast and slow examinees of equal ability. (Author/JKS)

The concurrent validity and reliability of abbreviated versions of the WISC-R were estimated for a group of one hundred children between six and sixteen years of age. These abridged scales offered satisfactory estimates of reliability and validity. (Author/JKS)

Reported are the development and testing of a scale measuring the attitudes of elementary school students toward physical education programs. (GW)

An analysis of the profiles of 1,243 secondary school students showed that 45 percent had the same Group cluster as their peak interest on two successive years, demonstrating the stability of the COPSystem interest classification. (Author)

Discusses the various factors required in the construction and validation of affective scales and synthesizes viable procedures drawn from several widely accepted sources. (HOD)

The Sixteen Personality Factor Questionnaire (16PF) was used to determine retest reliability (7-day interval) and motivational distortion for a sample of narcotic addicts (N=141) legally committed to treatment and tested by staff for routine diagnostic purposes. (Author)

The standard form Minnesota Multiphasic Personality Inventory (MMPI) and two abbreviated forms were compared with direct measures of psychopathology obtained from the Brief Psychiatric Rating Scale (BPRS). The multiple correlation coefficients between the BPRS ratings and the corresponding MMPI and abbreviated-form scales were significantly high…

Investigated in a series of experiments with 40 adults (20- to 70-years-old) having bilateral sensorineural hearing impairments was the test-retest reliability of the comfort level method for setting the acoustic gain of hearing aids, and the relationship between the comfort settings utilized in more realistic daily listening situations.…

To fully develop their diagnostic skills, medical students must recognize the limited reliability of the observations on which diagnoses are based. Study of 36 second-year students shows multiple sources of observer variation in readings of systolic and diastolic blood pressures. (LBH)
