The present research was aimed primarily at establishing and evaluating an In-Basket exercise and scoring procedures that greatly reduce training and scoring time while retaining adequate reliability and validity. In the first of two studies, an optimal subset of In-Basket items was identified for scoring. Their reliability and concurrent validity were then re-evaluated in a second, cross-validation study. No loss in reliability and little in validity resulted from the scoring-item reduction. In addition, results emerged that shed light on attainable In-Basket reliability and criterion-related validity. Implications for In-Basket use are noted.
