A quasi-experiment was used to determine whether training union officers in the skills necessary for implementing principles of organizational justice would increase citizenship behavior on the part of members of a labor union in Canada. The results showed that 3 months after training, the perceptio
A meta-analysis was conducted to estimate more accurately the bivariate relationships between leadership behaviors, substitutes for leadership, and subordinate attitudes, and role perceptions and performance, and to examine the relative strengths of the relationships between these variables. Estimates of 435 relationships were obtained from 22 studies containing 36 independent samples. The findings showed that the combination of the substitutes variables and leader behaviors account for a majority of the variance in employee attitudes and role perceptions and a substantial proportion of the variance in in-role and extra-role performance; on average, the substitutes for leadership uniquely accounted for more of the variance in the criterion variables than did leader behaviors.
In this article, hypotheses concerned with how race, gender, and mentoring experiences account for compensation outcomes among master of business administration (MBA) program graduates are considered. African-American and Hispanic MBAs were less likely than their White counterparts to establish mentoring relationships with White men. Women with MBAs were less likely than men with MBAs to form such relationships. Graduates who had been able to establish mentoring relationships with White men displayed an average annual compensation advantage of $16,840 over those with mentors displaying other demographic profiles. There were no compensation differences between those who had established mentoring relationships with women or minority men and those who had not established a mentoring relationship.
This study tests whether 2 types of response distortion (self-deception and impression management) affect the predictive validity of 2 of the "Big 5" personality dimensions, conscientiousness and emotional stability, in 2 applicant samples of long-haul semitruck drivers (n = 147 and n = 139). As hypothesized, conscientiousness (p = -.26 and -.26) and emotional stability (p = -.23 and -.21) were valid predictors of voluntary turnover in the 2 samples. Also as hypothesized, conscientiousness was a valid predictor of supervisory ratings of performance (p = .41 and .39) in the 2 samples. Although not hypothesized, emotional stability was also significantly related to supervisor ratings of performance (p = .23 and .27). Results from structural equations modeling indicated that applicants did distort their scores on both personality dimensions and the distortion occurred both through self-deception and impression management; however, neither type of distortion attenuated the predictive validities of either personality construct.
This study used meta-analytic methods to compare the interrater and intrarater reliabilities of ratings of 10 dimensions of job performance used in the literature; ratings of overall job performance were also examined. There was mixed support for the notion that some dimensions are rated more reliably than others. Supervisory ratings appear to have higher interrater reliability than peer ratings. Consistent with H. R. Rothstein (1990), mean interrater reliability of supervisory ratings of overall job performance was found to be .52. In all cases, interrater reliability is lower than intrarater reliability, indicating that the inappropriate use of intrarater reliability estimates to correct for biases from measurement error leads to biased research results. These findings have important implications for both research and practice.
Response bias continues to be the most frequently cited criticism of personality testing for personnel selection. The authors meta-analyzed the social desirability literature, examining whether social desirability functions as a predictor for a variety of criteria, as a suppressor, or as a mediator. Social desirability scales were found not to predict school success, task performance, counterproductive behaviors, and job performance. Correlations with the Big Five personality dimensions, cognitive ability, and years of education are presented along with empirical evidence that (a) social desirability is not as pervasive a problem as has been anticipated by industrial-organizational psychologists, (b) social desirability is in fact related to real individual differences in emotional stability and conscientiousness, and (c) social desirability does not function as a predictor, as a practically useful suppressor, or as a mediator variable for the criterion of job performance. Removing the effects of social desirability from the Big Five dimensions of personality leaves the criterion-related validity of personality constructs for predicting job performance intact.
On the basis of 7 charismatic and transformational leadership theories, 3 core components (vision, vision implementation through task cues, and communication style) were identified. A laboratory simulation manipulated the 3 components in a completely crossed experimental design, where 2 trained actors portrayed the leader. Participants were 282 students in upper level business classes who performed a simulated production task. The vision of high quality weakly affected performance quality but significantly affected many attitudes. Vision implementation, in the form of task cues, affected performance quality and quantity. Charismatic communication style affected only the perception of charisma. Mediation was not found ; rather, an exploratory path analysis found a 2-part causal sequence, where the vision of quality and vision implementation each affected self-set goals and self-efficacy, which, in turn, affected performance.
A longitudinal study of the functioning of top management teams in 27 hospitals examined relationships between group and organizational factors and team innovation. A model of group inputs, processes, and outputs was used, and it was predicted that group size, resources, team tenure, group processes, and proportion of innovative team members would affect the level and quality of team innovation. The results suggested that group processes best predict the overall level of team innovation, whereas the proportion of innovative team members predicts the rated radicalness of innovations introduced. Resources available to teams do not predict overall team innovation. The quality of team innovation (radicalness, magnitude, and novelty) may be determined primarily by the composition of the team, but overall level of innovation may be more a consequence of the team's characteristic social processes.
This study attempts to refine the construct of contextual performance by dividing it into 2 narrower constructs, interpersonal facilitation and job dedication. Supervisors rated 975 U.S. Air Force mechanics on at least 1 of 4 aspects of job performance (different supervisors rated each aspect of performance), and 515 of these mechanics also completed self-report individual difference measures. Correlations between performance ratings and individual difference variables support distinguishing task performance from interpersonal facilitation but not from job dedication. Thus this study suggests the need to redefine task performance to include motivational elements of job dedication. Then task performance would include task proficiency and motivation to perform one's own tasks effectively, and contextual performance would include interpersonal skills, the motivation to maintain good working relationships and help others perform their tasks.
