Most methods of personality scale construction have clear statistical disadvantages. A hybrid method (Darlington and Bishop, 1966) was found to increase scale validity more than any other method, with large item pools. A simple modification of the Darlington-Bishop method (algebraically and conceptually similar to ridge regression, but…

The Women's Liberation Scale (WLS) is a 14-item, Likert-type scale designed to measure attitudes toward positions advocated by women's groups. The WLS and its four-alternative response schema is presented, along with descriptive statistics of scores based on male and female college samples. Reliability and validity measures are reported, and the…

Identifying, acquiring, and developing valid and reliable instruments are major problems facing researchers who study psychosocial drug use and abuse. Much time is often devoted to creating a measuring device when an adequate one already exists, resulting in duplication of effort, considerable waste of resources, and loss of uniform comparability…

The Service Outcome Measurement Form (SOM) was the result of Service Outcome Measurement Project, and was developed and tested with the cooperation of Rehabilitation Administrators and Counselors in the state agencies of 11 states. The Project was designed to develop a method of measuring the relative difficulty of cases and to measure client…

This paper reports upon the evaluation and implementation of a 30-item Likert-type rating scale for teachers to use in assessing children's behaviors within preschool classrooms. The Preschool Observation Scale (POS) was developed to evaluate programs of the Mt. Druitt Early Childhood Project, North Ryde, Australia. Items were constructed on the…

In an effort to minimize initial testing of adult students, a ten-item "Adult Reading Survey" was developed to measure self-perception as related to reading ability. Survey responses of 184 adult education students ranging in age from 15 to 68 were correlated to reading test results to determine levels of accuracy. Portions of two tests, the "Test…

In the late spring of 1972, the Chancellor's Office agreed to support a summer study to be undertaken by a committee of the California English Council, to investigate equivalency testing in the area of English and to recommend an appropriate program for use by the California State University and Colleges. This report is the result of that study:…

Since the 1974 California State University and Colleges Freshman English Equivalency Examination was a repeat of the 1973 examination, the report contained in this document should be viewed as a supplement to the 1973 report. The test was administered in May 1974 to 3,639 students with 1,036 receiving proficiency credit. Once again, it consisted…

As part of the development of a classroom interaction observation instrument, this report presents the results of a comparative study of group interaction in contrasting educational environments (open and traditional) with children of different socioeconomic backgrounds (middle and lower classes). Additionally, problems of adequately assessing…

The Principles of Adult Learning Scale (PALS) was developed and validated for measuring congruency between adult education practitioners' actual observable classroom behavior and their expressed belief in the collaborative teaching-learning mode. This model is a learner-centered instruction method in which learner and practitioner share authority…
