Most psychological tests and inventories, particularly in personality and attitude measurement, contain common items. The present report specifically considered common-item contributions to test internal consistency reliability using extant data from the California Psychological Inventory. No negative contribution of item overlap was found.…

A new inventory for examining the first six of Erikson's psychosocial stages is described. It is concluded that the Erikson Psychosocial Stage Inventory (EPSI), a self-report questionnaire, is a useful measure for researchers interested in development from early adolescence and in mapping changes as a function of life events.

In mastery testing, the raw agreement index and the kappa index may be estimated via one test administration when the test scores follow beta-binomial distributions. This paper reports formulae, tables, and a computer program which facilitate the computation of the standard errors of the estimates. (Author/CTM)

Two procedures for scoring the Recreation Experience Preference scales were investigated using data obtained from respondents engaged in outdoor recreational activities. Both procedures yielded acceptable levels of reliability and concurrent validity. When time is unimportant, the scale score strategy is preferred over the domain score strategy.…

Examined imagery questionnaires and addressed issues of reliability, agreement among questionnaires, social desirability, and construct validity. The Betts and Gordon scales and the Paivio Individual Differences Questionnaire were examined. Reliability of the Paivio inventory was satisfactory and equivalent to other imagery questionnaires. Imagery…

The purpose of this research was to develop a self-concept scale for gifted students which focused on gifted children's talents and abilities and associated or related behaviors. Preliminary development analyses for 224 gifted girls and 188 boys in Grades 3 through 6 indicate promising reliability and possibly good validity. (Author/SJL)

Limitations and extensions of Feldt's approach to testing the equality of Cronbach's alpha coefficients in independent and matched samples are discussed. In particular, this approach is used to test equality of intraclass correlation coefficients. (Author)

The Preschool-Primary Nowicki-Strickland Internal-External Control Scale (PPNSIE) was used to assess the locus of control in 359 mildly retarded secondary students. Unacceptably low reliability estimates for the PPNSIE were revealed, with IQ and age the strongest predictors of scores. (CL)

The strengths of the scales were concentrated in the areas of domain and construct validity, weaknesses in the areas of discriminant validity, interobserver reliability, and decision-making reliability. (DB)

The increasing use of various VO2 max expressions as test measures is a problem because the magnitude of sex difference varies considerably with each expression. A valid match of male and female test subjects would consider physical activity history and the amount of endurance exercise done in the previous year. (Author/FG)

The study aimed to develop an instrument that could be used for mental health research with Spanish-speaking populations. The Depression Adjective Check Lists (DACL) used to measure depressive mood was translated into Spanish and administered to 70 Hispanic subjects. Reliability determinations were high and close to those for the English version.…

A chain of lower bound inequalities leading to the greatest lower bound to reliability is established for the internal consistency of a composite of unit-weighted scores (such as a test). Algorithms for obtaining various reliability coefficients are presented. (Author/JKS)

To assess the stability of the factor structure of the Instructional Improvement Questionnaire (IIQ), factor analyses were run for 1973, 1974, and 1975 results, partialling out three variables: expected grade, percent taking the course as an elective, and student's year. The factors were stable over the three years. (Author/BW)

Describes the procedures the authors of the System for Career Decision-Making (CDM) followed in establishing client scoring reliability. Authors recommend that manuals of self-scored inventories provide data establishing scorer reliability, that scoring be supervised, and that APGA test standards deal directly with scorer reliability.

The purpose of this study was to investigate the structure of motor proficiency in a sample of 765 children between the ages of 4 1/2 to 14 1/2 years. The study was conducted as one aspect of the standardization of a motor proficiency scale, the Bruininks-Oseretsky Test of Motor Proficiency. (Author/SJL)
