Tests of the Three-Path Mediated Effect:

Although mediational designs and analyses are quite popular in Organizational Behavior research, there is much confusion surrounding the basis of causal inferences. We review theoretical, research design, and construct validity issues that are important for drawing inferences from mediational analyses. We then distinguish between indirect effects, and partial and full mediational hypotheses and outline decision points for drawing inferences of each type. An empirical illustration is provided using structural equation modeling (SEM) techniques, and we discuss extensions and directions for future research. Copyright © 2006 John Wiley & Sons, Ltd.

Clarifying conditions and decision points for mediational type inferences in Organizational Behavior

Purpose – The purpose of this article is to provide an overview for those interested in the current state‐of‐the‐art in time management research.Design/methodology/approach – This review includes 32 empirical studies on time management conducted between 1982 and 2004.Findings – The review demonstrates that time management behaviours relate positively to perceived control of time, job satisfaction, and health, and negatively to stress. The relationship with work and academic performance is not clear. Time management training seems to enhance time management skills, but this does not automatically transfer to better performance.Research limitations/implications – The reviewed research displays several limitations. First, time management has been defined and operationalised in a variety of ways. Some instruments were not reliable or valid, which could account for unstable findings. Second, many of the studies were based on cross‐sectional surveys and used self‐reports only. Third, very little attention was g...

A review of the time management literature

Although interruptions are daily occurring events for most working people, little research has been done on the impacts of interruptions on workers and their performance. This study examines the e Vects of interruptions on task performance and its regulation, as well as on workers’ psychological and psychophysiological state. Two parallel experiments were carried out in the Netherlands and in Russia, using a common conceptual framework and overlapping designs. Employees with relevant work experience carried out realistic text editing tasks in a simulated o Yce environment, while the frequency and complexity of interruptions were experimentally manipulated. It was hypothesized that interruptions: (i) would cause a deterioration of performance; (ii) evoke strategies to partially compensate for this deterioration; (iii) aVect subjects’ emotions and well-being negatively; and (iv) raise the level of eVort and activation. It was also hypothesized that greater frequency and complexity of interruptions would enhance the expected e Vects. The hypotheses are only partially cone rmed. The results show that, contrary to what was expected, interruptions cause people to perform the main task faster while maintaining the level of quality. Participants develop strategies enabling them to deal e Vectively with the interruptions, while actually over-compensating the potential performance decline. Interruptions do have a negative impact on emotion and well-being, and lead to an increase of e Vort expenditure, although not to an increase in activation. Thus the improved performance is achieved at the expense of higher psychological costs. Greater complexity evoked more favourable responses among the Dutch participants and more unfavourable ones among the Russian participants. These diVerences are interpreted in terms of the participants’ professional background. The research demonstrates that the e Vects of interruptions reach beyond the execution of additional tasks and the change of work strategies. Interruptions appear to have an after-e Vect, ine uencing the workers’ subsequent readiness to perform. Detailed analysis of the activity in the interruption interval, focusing on

Temporal factors in mental work: effects on interrupted activities

We investigated grit and its relations with students’ self-regulated learning (SRL) and academic achievement. An ethnically diverse sample of 213 college students completed an online self-report survey that included the Grit Short scale (Duckworth and Quinn Journal of Personality Assessment, 91(2), 166–174, 2009), seven indicators of SRL and their past and present academic achievement. Results indicated that one aspect of grit, perseverance of effort, was a consistent and adaptive predictor for all indicators of SRL including value, self-efficacy, cognitive, metacognitive, motivational, time and study environment management strategies, and procrastination. A second aspect of grit, consistency of interest, was associated only with the latter two facets of SRL. Perseverance of effort predicted achievement before, but not after, accounting for SRL; hence, students’ engagement in SRL may serve as a mediating pathway through which this aspect of grit is associated with improved academic outcomes. In contrast, consistency of interest showed no relation to achievement. Implications of the findings for additional research and instruction are discussed.

Investigating grit and its relations with college students’ self-regulated learning and academic achievement

This study investigated two mediation models of time management. The first model consisted of parts of Macan's (1994) model. The second model combined this model with Karasek's (1998) Job Demand–Control model. Two sets of self-report questionnaires were collected and were analyzed using structural equation modeling. The first model, in which perceived control of time was hypothesized to fully mediate the relation between planning behavior and work strain, job satisfaction, and job performance, was found to be less adequate than the second model, which added workload and job autonomy as independent variables. Results also indicated that partial, rather than full, mediation of perceived control of time fitted the data best. The study demonstrated the importance of studying both planning behavior and job characteristics, which was not part of past research. Copyright © 2004 John Wiley & Sons, Ltd.

Planning behavior and perceived control of time at work

In a survey among respondents from 96 organizations, we found that the utility of training partially mediated the relationship between Training Needs Assessment (TNA) comprehensiveness and the effectiveness of the organization. We did not find an effect of training quantity on training utility and organization effectiveness. Both TNA comprehensiveness and training quantity were found to be unrelated to organizational size. The results support the importance of conducting TNA in practice.

The mediating role of training utility in the relationship between training needs assessment and organizational effectiveness

Purpose
The purpose of this study was to test a model that proposes that innovative cognitive style and self-regulation (setting priorities, planning work activities, and monitoring time and task progress) are related to the self-reported success of architects. We investigated two aspects of the success: as designers and as business people. To this end, we examined the mediating role of self-efficacy in these relationships.

Being successful in a creative profession: The role of innovative cognitive style, self-regulation, and self-efficacy

Some time away from a problem, or incubation time, is found to be beneficial to creative problem solving. But are interruptions as equally helpful as breaks? An experiment was conducted to gain more insight into the differences between imposed and self-initiated breaks, and their effects on creativity, specifically on impasses and insights. There were three experimental conditions, (a) a continuous condition, in which participants were not allowed to switch back and forth between tasks, (b) an interruption condition, in which participants had to switch tasks at a predetermined moment, and (c) a break condition, in which participants could switch tasks at their own discretion. Results showed that taking breaks at moments chosen at one's own discretion led to solving more insight problems and reaching fewer impasses than at moments that were chosen by others. Furthermore, compared to working continuously, interruptions led to fewer impasses, but not to solving more insight problems.
