Mental energy: Assessing the motivation dimension.

Content-based theories of motivation may best uti lize the meta-theory of work motivation. Process-based theories may benefit most from adopting Locke and Latham's goal-setting approaches and measures. Decision-making theories should utilize the measurement approach operationalized by Ilgen et al. Sustained effort theories should utilize similar approaches to those used in numerous studies of intrinsic motivation, but the measurement of which is typically observational or attitudinal. This paper explored the implications of the four approaches to studying motivation on the newly estab ished model of mental energy. The approach taken for examining motivation informs the measurement of mental energy. Specific recommendations for each approach were developed and provided. As a result of these efforts, it will now be possible to diagnose, measure, and experimentally test for changes in human motivation, which is one of the three major components of mental energy.

Four classification schemes of adult motivation: current views and measures.

Classification of perspectives on motivation and recommendations for measurement are provided. Motivation is classified into four broad categories: content theories, process theories, decision-making theories, and sustained-effort theories--drawing from different theories and measures. Recommendations on measurement are developed for each classification scheme of motivation.

Sources of motivation, interpersonal conflict management styles, and leadership effectiveness: a structural model.

126 leaders and 624 employees were sampled to test the relationship between sources of motivation and conflict management styles of leaders and how these variables influence effectiveness of leadership. Five sources of motivation measured by the Motivation Sources Inventory were tested-intrinsic process, instrumental, self-concept external, self-concept internal, and goal internalization. These sources of work motivation were associated with Rahim's modes of interpersonal conflict management-dominating, avoiding, obliging, complying, and integrating-and to perceived leadership effectiveness. A structural equation model tested leaders' conflict management styles and leadership effectiveness based upon different sources of work motivation. The model explained variance for obliging (65%), dominating (79%), avoiding (76%), and compromising (68%), but explained little variance for integrating (7%). The model explained only 28% of the variance in leader effectiveness.

Preliminary relation between followers' locus of control and organizational citizenship behaviors.

This study estimated the relationship between followers' locus of control and organizational citizenship behaviors for a sample of 375 government employees, whose M age was 46 yr. 53% were women; 42% earned bachelor's degrees. Analyses showed a significant positive correlation of .35 between followers' locus of control and their organizational behaviors. More complex models and research designs are necessary to generalize.

A validity generalization procedure to test relations between intrinsic and extrinsic motivation and influence tactics.

The relations of intrinsic and extrinsic motivation with use of consultative, legitimating, and pressure influence tactics were examined using validity generalization procedures. 5 to 7 field studies with cumulative samples exceeding 800 were used to test each relationship. Significance was found for relation between agents' intrinsic motivation and their use of consultative influence tactics and agents' extrinsic motivation and their use of legitimating influence tactics.

Testing antecedents to sales performance in postapartheid era: a field study.

The predictors of objectively measured sales performance were assessed with 245 sales representatives from a large South African life insurance company. Sales representatives completed measures of their locus of control, entrepreneurial attitudes, biographical history, and performance was assessed from company records of sales, net commissions earned, and lapse ratios. The nature of employment contract, job status, and race explained significant differences in performance outcomes. The predictive nature of locus of control and entrepreneurial attitudes for performance outcomes was tested using structural equation modeling procedures, with limited validity. The implications for research and practice are also discussed.

The emotional intelligence of transformational leaders: a field study of elected officials.

Participants were 80 elected public officials in the United States and 3-6 direct-report staffers for each leader. Together they composed 388 leader-member dyads. The authors surveyed them to explore the relationship between emotional intelligence and transformational leadership. The authors considered the 80 officials as leaders and the staffers as members. The present results showed that the emotional intelligence of the leaders shared significant variance with self-perceptions and rater-perceptions of transformational leadership. The present results also somewhat support the predictive value of emotional intelligence in antecedent leadership field research.

Influence of sex differences in leaders' behavior.

Sex differences in influence tactics were examined with a sample of 269 followers (67 men, 202 women) at a large midwestern national insurance company who rated the downward influence tactics used by their direct supervisors. Downward influence tactics are behaviors used by leaders to gain compliance from followers. One department within the organization was identified as a source for participants in the study. Participation was voluntary. The age range for the sample was 21 to 65 years, with the largest percentage falling in the 40-49 year range (M = 3.8, SD = .8). Hierarchical linear modeling procedures were utilized to analyze the multiple level data (leader and follower) and to examine variables within the organization at different levels of analysis. Leader participants were asked to solicit their followers to complete an influence tactic measure, which consisted of the most reliable subscales taken from the Influence Behavior Questionnaire, Schriesheim and Hinkin Influence Measure, and the Profiles of Organizational Influence Strategies. The integrated measure resulted in a 45-item scale. It was hypothesized that, overall, followers would report that male leaders would use hard influence tactics more frequently than female leaders. On the other hand, followers would report that female leaders would use soft influence tactics more frequently than male leaders. When differentiating followers by sex, however, we expected that male followers would report more than female followers that their leaders use hard tactics more frequently. Also, we expected that female followers would report (more than male followers) that their leaders use soft tactics more frequently. Overall, followers reported that male leaders used significantly more personal appeal and consultation, so called "soft tactics," with their followers than did female leaders. Female followers reported that their leaders (both male and female) used consultation and inspirational appeal more frequently. In contrast, male followers reported that their leaders used exchange, so called "hard tactics," more frequently.

Comments on "The effects of leader-member exchange and differential treatment on work unit commitment": distinguishing between neutralizing and moderating effects.

Van Breukelen, Konst, and van der Vlist in 2002 examined how members' perceptions of differential treatment from the leader affect the relationship between Leader-Member exchange and work unit commitment. This paper offers commentary, with specific focus on the judgment call for examining continuous effects across all levels of differential treatment. To justify the role of differential treatment as a neutralizer that weakens the influence of Leader-Member exchange on work unit commitment, the regression coefficients of work unit commitment on Leader-Member Exchange should be examined continuously with discriminable differential treatment. As a caution against using "neutralizer" based on the research results presented, "moderator" is suggested as the more appropriate descriptor of the role that differential treatment played. Also, the nature of the interaction between Leader-Member exchange quality and work unit commitment is explored, suggesting research should focus more on the main effects.

Machiavellianism's association with sources of motivation and downward influence strategies.

Recent studies have examined the relationship between motivation and influence tactics with mixed results. Barbuto and Scholl found several strong relationships between leaders' sources of motivation and the influence tactics used when influencing subordinates, but replication yielded weaker relationships between motivation and influence tactics. Examinations of moderating variables such as leaders' Machiavellian disposition were suggested as possible explanations for this difference. Several interacting effects between leaders' sources of motivation and Machiavellianism have been proposed as predictors of the influence tactic used. This study tested these relationships and found modest association between motivation sources and influence tactics. Some moderating effects of Machiavellianism on this relationship were evident: however, interpretation is cautioned given poor psychometric properties of the measure. These issues are discussed along with suggestions for research.

Exploring relationships between college students' learning styles and motivation.

A pilot study explored the relationships between learning styles and motivation for a sample of 103 undergraduate and graduate students who completed both the Approaches to Studying Inventory and the Motivation Sources Inventory online. A significant positive but small correlation was found between scores on Surface Apathetic Approach and on Self-concept Internal motivation (r =.32, p< .01). Significant negative correlations were found between scores on Surface Apathetic Approach and on Self-concept External motivation (r = -.32, p < .01), and for Strategic Approach and Self-concept Internal (r =-.37, p<.01). Implications and further research are discussed.

Motivation, altruism, and generalized compliance: a field study of organizational citizenship behaviors.

This study tests the relations among five sources of motivation and two organizational citizenship behaviors. 175 employees from 31 locations of two agriculturally based companies completed the Motivation Sources Inventory and were rated by their supervisors for demonstrated organizational citizenship behaviors. There were significant positive correlations for employees' Self-concept-Internal Motivation with Altruistic Behavior of employees; while employees' Self-concept-External Motivation showed a significant negative relation with Altruistic Behavior by employees. Surprisingly, no correlation between employees' Goal Internalization Motivation and Altruistic Behavior by employees was found. Interpretation of these findings and further research are suggested.

Sex differences among five sources of motivation in the motivation sources inventory: preliminary findings.

Paper reports sex differences among five sources of motivation for a sample of 208 undergraduate students who completed the Motivation Sources Inventory. t tests yielded few statistically significant sex differences for the five sources of motivation; however, Instrumental Motivation was higher among men than women, while the remaining four motives showed no sex difference. Implications and research opportunities are discussed.

A field examination of two measures of work motivation as predictors of leaders' influence tactics.

The authors tested 2 motivation measures, the Motivation Sources Inventory (MSI; J. E. Barbuto & R. W. Scholl, 1998) and the Job Choice Decision-Making Exercise (A. M. Harrell & M. J. Stahl, 1981) as predictors of leaders' influence tactics. The authors sampled 219 leader-member dyads from a variety of organizations and communities throughout the central United States. Results strongly favored the MSI as a predictor of influence tactics. Limitations of the study include low power of relationships, sample size as limited by the research design, and education levels of participants. Future researchers should use larger and more diverse samples and test other relevant antecedents of leaders' behaviors.

Leaders' anticipated and targets' self-reported resistance to task assignments: a replication.

This is a follow up study of Barbuto's 2000 work in which leaders' ratings and targets' self-reported resistance to task assignments are compared. Scores on the Anticipated Resistance Indicator among 650 leader-member dyads measure resistance based on Barbuto's 1997 five concentric zones of Preference, Indifference, Legitimate, Influence, and Noninfluence, examined from both leaders' and targets' perspectives. Responses indicated that leaders tend to underestimate followers' willingness to perform assigned tasks. In addition, leaders tend to overestimate targets' unwillingness to perform undesirable, less enjoyable tasks.

Correlations for leaders' anticipation of targets' resistance and targets' ratings of leaders' influence tactics: a replication.

A sample of 553 leader-target dyads was used to replicate the 2001 work of Barbuto, Scholl, Hickox, and Boulmetis. The study examined the correlation between leaders' anticipation of targets' resistance and influence tactics used by leaders to persuade targets. The original study reported mixed findings of various hard and soft tactics used by leaders based on the different zones of resistance anticipated. Present results show no relation between leaders' anticipation of targets' anticipated resistance and the influence tactics used.
