The purpose of this study was to examine the construct validity of social loafing using convergent and discriminant validity principles. Three instruments that purport to measure social loafing were factor analyzed: A ten-item instrument by George (1992), a 13-item instrument by Mulvey and Klein (1998), and a 22-item instrument by Jassawalla,…

Purpose: The aim of this study was to identify the effects of a differential-learning program, embedded in small-sided games, on the creative and tactical behavior of youth soccer players. Forty players from under-13 (U13) and under-15 (U15) were allocated into control and experimental groups and were tested using a randomized pretest to posttest…

Relationships among self-construal, self-efficacy, and group behaviors during a group problem-solving task with friends and acquaintances were hypothesized. The sample comprised 126 students in Grades 8-11, from 5 randomly selected government high schools, organized into 42 groups. Data collection involved self-reports and observations.…

In order to train young professionals, instructional methodologies in engineering need not only teach students knowledge, but must also instill the values and teach the behaviors--"competencies" students can demonstrate--required of professional practice. Herein, we focus on understanding the values and behaviors of students with respect…

These authors have previously described how to use the "t" test to compare two groups. In this article, they describe the use of a different test, analysis of variance (ANOVA) to compare more than two groups. ANOVA is a test of group differences: do at least two of the means differ from each other? ANOVA assumes (1) normal distribution…

This study used an experimental approach to investigate the conditions under which creative outcomes should be expected from the interplay of individual creativity, the innovation orientation of the organizational culture, and the rewards distribution rules. The results of this study suggest that the individual creativity of technically educated…

We illustrate the idiographic/nomothetic debate by comparing 3 approaches to using daily self-report data on affect for predicting relationship quality and breakup. The 3 approaches included (a) the first day in the series of daily data; (b) the mean and variability of the daily series; and (c) parameters from dynamic factor analysis, a…

We developed a dual-level transformational leadership scale to measure individual-focused behavior at the individual level and group-focused behavior at the group level, and we validated the scale using a sample of 203 members from 60 work groups in a Canadian company. Results show that individual-focused leadership behavior, at the individual…

A new measurement tool for individualism and collectivism has been developed to address critical methodological issues in this field of social psychology. This new measure, the Auckland Individualism and Collectivism Scale (AICS), defines three dimensions of individualism: (a) responsibility (acknowledging one's responsibility for one's actions),…

There is paucity of original research that explains phenomena related to content organization and site design of educational Web sites. Educational Web sites are often used to provide Web-based instruction, which itself is a relatively recent phenomenon for business schools, and additional research is needed in this area. Educational Web sites are…

Describes research used to develop an original instrument, the Workforce Diversity Questionnaire, to assess interactions in diverse workgroups. States that a set of proposed dimensions was developed theoretically from literature on cultural diversity, discrimination, and intergroup processes. Explains how validity was tested through confirmatory…

A variable rule of /s/ deletion that operates in many varieties of Spanish is examined. A descriptive apparatus is posited that may be helpful in systematizing quantitative data from studies of phonological variability. Empirical data from the speech of informants show that ordering relationships among constraints on variable phonological rules…

An instrument was developed and tested which would measure intermediate interaction behavior in small-group communication. The study was designed to uncover the several dimensions of such behavior and produce a reliable, valid measure for each dimension that would yield data amenable to parametric statistical analysis. Analysis of two experiments…

Revised Thelen's (1954) Group Emotionality Rating System, developing new criteria and assessment procedures. A reliability study of 4,343 verbal statements from 6 different Norwegian groups revealed an overall agreement of .77, with the emotionality subcategories ranging from .57 to .67. Discusses validity of the emotionality categories according…
