This paper investigated the reliability and construct validity of a 30-item scale in measuring the attitudes of teachers in Australia toward the integration of handicapped children into regular schools. The Attitude Toward Mainstreaming Scale, which was designed by Larrivee and Cook (1979), has been used in evaluation studies in the United Sates…

Using the constructs of Rogers, Ellis, and Barrett-Lennard, a twenty-five item Likert-type instrument, the Non-Directive Supervisory Behavior Scale, was developed to measure directive vs. non-directive supervisory behavior. One hundred ninety-five in-service teachers, randomly selected from two school districts, completed the twenty-five item…

This study was designed to factor analyze the correlation matrices of a number of studies utilizing the Illinois Test of Psycholinguistic Abilities (ITPA). All of the correlation matrices were analyzed on the same program using the same criteria. By this approach, it was possible to examine trends between studies. More factors tended to appear as…

The construction of an objective, self-report, objectively-scored measure of achievement motivation is reported. Empirically keyed items were developed, reflecting empirical results found in a review of achievement motivation literature. An initial item pool consisting of 153 self-report items was administered using a matrix sampling approach to…

Four hospitalized female schizophrenics performed self ratings on a battery of variables for 60 consecutive days. The results are discussed in relation to nomothetic vs. idiographic systems of psychology and the study of intraindividual change by P-technique as a methodology of clinical interest. (DEP)

Two studies investigated the functional equivalence of three different scoring systems used to assess the child's ability to understand and carry out multiplicative classification tasks. All three scoring criteria produced reliable and homogeneous tests. Their factor matrices were similar, and the corresponding factor structures were invariant…

A shortened version of Zaichkowsky's 20-item Personal Involvement Inventory was created, removing four items which might be difficult to understand for noncollege-educated populations. The 16-item modified version had acceptable internal consistency; test-retest reliability; and factorial and predictive validity. (Author/GDC)

This paper presents the development of a new measure of locus of control for adults, the Internal Control Index. Analysis of a field test and a junior college administration indicated an estimated reliability of .84, the presence of a strong principal component, two replicable factors, and evidence for convergent validity.

The reliability and validity of the Multidimensional-Multiattributional Causality Scale was examined for 350 American community college students, ranging in age from 17 to 59. The attributions of ability, effort, context, and luck emerged as well as distinctions between attributions related to academic success or failure. (Author/PN)

Providing additional data concerning the reliability and discriminant validity of Aiken's Enjoyment of Mathematics and Value of Mathematics Scales resulted in a degree of correlation between scales lower than for Aiken's data. Also, the view that the scales measure different aspects of attitude toward mathematics was supported. (PN)

The Self-Description Questionnaire III (SDQ III) was designed to measure 13 factors of self-concept. The reliabilities of the factors were high, and correlations among them were low. Academic achievement measures in language and mathematics were correlated with self-concepts in the same areas but not with other self-concept factors. (Author/DWH)

The mental growth patterns of 204 children were investigated on four different test occasions covering a five-year period, ages six to 11. There is no evidence of intellectual differentiation after age six nor is there a systematic decline in size of WISC subtest intercorrelations with increasing age. (Authors)

Construct validity of the six scales of the Career Development Inventory was investigated with 312 tenth-grade students. The subscales were found to demonstrate adequate discriminant validity except for certain cognitive subscales. (Author/CP)

Seven separate studies over 3.5 years developed the Trauma-Related Guilt Inventory, examined its internal consistency, factor structure, and the questionnaire's convergent and discriminant validity. Results with college students, veterans, and battered women support the conceptualization of trauma-related guilt as a multidimensional construct.…
