Sociology students were administered two Thurstone-type attitude scales under two conditions (with or without a "cannot decide" option), and a measure of ambiguity tolerance. The "cannot decide" option was used by a slight majority of students when available, but usage was not related to ambiguity tolerance. (Author/JKS)

Test-retest item instability indices for low, middle, and high scores on the Piers-Harris Children's Self-Concept Scale were calculated in order to test the hypothesis that low scores are invalid because of unreliability of responding. The hypothesis was not supported. (Author/JKS)

The diversity among interpretations of single items in personality questionnaires has been noted previously. Using adjectives from the Adjective Check List (ACL), the study sought evidence bearing on these questions: Does such diversity make the responses to an item not comparable across subjects? If so, what are the implications for scores based…

An alternative way of studying group differences is proposed based on ordering analysis using item hierarchies as a basis of comparison between two groups. Subjects were sets of twins in elementary school. Results showed that blacks and whites and males and females had similar item hierarchies for complex items. (Author/LMO)

This paper reviews the application of the EM Algorithm to marginal maximum likelihood estimation of parameters in the latent class model and extends the algorithm to the case where there are monotone homogeneity constraints on the item parameters. It is shown that the EM algorithm can be used to obtain marginal maximum likelihood estimates of the…

An empirical comparison of the validity of three Likert-type attitude scales measuring fourth to sixth grade students' attitudes toward school integration was conducted. The content-parallel forms differed only in terms of item phrasing and were composed of either all positive, all negative or a mix of items. Different factor solutions underlying…

Measures of consistency and completeness of order relations derived from test-type data are proposed. The measures are generalized to apply to incomplete data such as tailored testing. The measures are based on consideration of the items-plus-persons by items-plus-persons matrix as an adjacency matrix in which a 1 means that the row element…

A multiple true-false item is one where a testee has to identify statements as true or false within a cluster (of two or more) of such statements. Clusters are then scored as items. This study showed such a procedure to yield less reliable results than traditional true-false items. (JKS)

The random response technique was compared to a direct questionnaire, administered to college students, to investigate whether or not the responses predicted the social desirability of the item. Results suggest support for the hypothesis. A 33-item version of the Marlowe-Crowne Social Desirability Scale which was used is included. (GDC)

Major aim of this study was to distinguish clearly between two interpretations of acquiescence response style. (Authors)

Multidimensional scaling (MDS) and components solutions were compared using two balanced self-report item sets. Results suggest that when self-report items are balanced and negatively worded items are not reverse scored, MDS and components solutions can differ largely, due to a component associated with measures of acquiescence. (SLD)

Higher education scholars and institutional researchers rely heavily on self-reported survey data in their work. This chapter explores problems associated with self-reports and provides questions and recommendations for their use.

Undergraduates responded to an objective test in electronics and classified each item by domain (one of 14 topics covered in their text), and by type of knowledge (definition, fact, principle, or interpretation). These judgments were compared to their instructor's "standard" judgments. From these data, an index of item-domain divergence…

Stability of performance on a criterion referenced reading test was examined for 413 students in grades one through six. The test, which measures 367 behavioral reading objectives, was administered twice to each student, with an interval of at least three weeks between the first and second administrations. Three statistical indices of permanence…
