Item Selection Counts: A Comparison of Empirical Key and Rational Scale Validities in Theory-Based and Non-Theory-Based Item Pools

Little explicit attention has been given to the impact of item pools on the validities and cross-validities of different background data scoring approaches. This study tests the idea that pools of items theoretically related to the performance of interest will outperform pools of items with no hypothesized relationship with the criterion. Validities and cross-validities of rational scales and empirical keys created from theory- and non-theory-based item pools were compared for 3 criteria. When size of the item pools was held constant, theory-based empirical keys (correlational and vertical percent) and rational scales showed larger validities and cross-validities than non-theory-based empirical keys (correlational and vertical percent) and showed minimal shrinkage in cross-validities. Even when item pool for the non-theory-based keys was expanded to include all items in the instrument, the theory-based keys showed comparable or slightly better validities and cross-validities for 2 of the 3 criteria, including college GPA, which was separated from the predictors by 4 years

Solving Everyday Problems Creatively: The Role of Problem Construction and Personality Type

Problem construction has been determined to be an important process contributing to creative problem solving. The purpose of this study was to investigate whether problem construction plays a role in how individuals interpret ambiguous, ill-defined problems in a way that fits with their personality. We also hypothesized that solution quality and originality would be related not only to problem construction ability but also to the degree to which the solution fits the personality of the individual. Students who participated in this study (N = 195) were asked to complete measures to identify personality types, a measure of problem construction ability, and a problem-solving exercise. Solutions were rated for fit of the solution to the personality, quality, and originality. Results suggest that problem construction ability is positively related to the fit of the solution to the personality type, and that solution quality and originality are related to both problem construction and solution fit. Implications of the role of problem construction in solving everyday problems are discussed

Problem Construction and Creativity: The Role of Ability, Cue Consistency, and Active Processing

Problem construction has been suggested as the first step in creative problem solving, but our understanding of the underlying process is limited. According to a model of problem construction (Mumford, Reiter-Palmon, & Redmond, 1994), problem construction ability, active engagement in problem construction, and the presence of diverse and inconsistent cues influence creative problem solving. To test these hypotheses, 195 undergraduates were asked to solve 6 real-life problems and complete a measure of problem construction ability. Active engagement in problem construction was manipulated by instructions to the participants. Cue consistency was manipulated by the information presented in the problem situation. The quality, originality, and creativity of the solutions were evaluated. Results indicated that problem construction ability was related to higher quality solutions as well as solutions rated as more original. Problem construction ability also interacted with cue consistency such that individuals with high problem construction ability produced solutions of higher quality and originality when faced with inconsistent cues. The implication of these findings to our understanding of creative problem solving and the problem construction process are discussed

Development of leadership skills: Experience and timing

To develop organizational leaders we need to understand how requisite skills are acquired over the course of people\u27s careers. In this article, a cross-sectional design was used to assess differences in leadership skills across six grade levels of officers in the U.S. Army. Increased levels of knowledge, problem-solving skills, systems skills, and social skills were found at higher grade levels. Certain skills and experiences, however, were found to be particularly important at certain phases of leaders\u27 careers. These findings are used to propose an organization-based model of skill development. Implications of this model for leader development programs are discussed

Evaluating the effectiveness of KooLKIDS : an interactive social emotional learning program for Australian primary school children

The effectiveness of universal social emotional learning (SEL) programs are dependent on the incorporation of best practice principles, including an evaluative component. In the present study, the effects of a best practice, teacher-led SEL program was examined with 854 children aged 8–12 years. KooLKIDS uses an interactive multimedia format and animated character to help children develop their emotion regulation capacities, social and friendship skills, empathy and compassion for others, and self-esteem. A quasi-experimental waitlist-control design was used to examine the impact of KooLKIDS on social and emotional competence, behavioral and emotional problems, academic achievement and effort. Hierarchical linear modeling demonstrated significant increases in social and emotional competence, and reductions in internalizing and externalizing problems in children post KooLKIDS program in the intervention group. The findings suggest that KooLKIDS has strong potential as a teacher-led, classroom-based, structured program for enhancing children's social and emotional learning
