This study compared four methods for setting item response time thresholds to differentiate rapid-guessing behavior from solution behavior. Thresholds were either (a) common for all test items, (b) based on item surface features such as the amount of reading required, (c) based on visually inspecting response time frequency distributions, or (d)…

This study evaluated the validity of the Type A behavior pattern as measured by paper-and-pencil questionnaires. The Jenkins Activity Survey, Framingham Type A Scale, Thurstone Activity Scales, a new bipolar adjective Type A measure, and measures of achievement and nurturance needs were completed by 418 students.

The construct validity of 290 preadolescent children's responses to 3 instruments claiming to measure dimensions of self-concept was studied. Instruments administered to the fifth graders include the Self-Description Questionnaire; the Perceived Competence Scale; and the Piers-Harris Children's Self-Concept Scales. (SLD)

Equivalence in reliability and validity across 4-point and 6-point scales was assessed by fitting different measurement models through confirmatory factor analysis of a multitrait-multimethod covariance matrix. Responses to nine Likert-type items designed to measure perceived quantitative ability, self-perceived usefulness of quantitative…
