    A longitudinal multilevel mediation model

    This study seeks to explain the interplay between chronological age and technology-related strain through techno-stressors and coping strategy choices in organizational settings. Grounded in Lazarus® stress theory, theories of cognitive aging, the life span theory of control and socioemotional selectivity theory, this study argues that even though older workers are more prone to techno-stressors, aging is connected to gaining coping skills, which in turn reduce technology-related strain over time. Understanding these processes enables modifying employees’ coping strategy choices and mitigating negative outcomes of technostress at the workplace. Longitudinal data from 1,216 employees over a time period of 8 months were used to perform multilevel mediation modeling. The findings reveal that age was negatively related to technology-related strain. The link between age and technology-related strain was explained through behavioral disengagement, which older workers used less than younger workers. Active coping and social coping did not act as mediators of this relationship across time points. These relationships were stable after controlling for dependency on technology

    Age Mitigates Adverse Effects of Low Implicit–Explicit Motive Congruency on Work Motivation

    This study examines the effects of implicit and explicit motives at work. Specifically, we hypothesize that congruency of implicit and explicit motives (i-e congruency) affects work motivation. Integrating research on age-related gains in self-regulation strength, we expect that negative effects of low i-e congruency on work motivation are more detrimental for younger than older workers, because they possess fewer self-regulation skills. The age moderation effect should be further qualified by motive-specific incentives, such that low i-e congruency has most detrimental effects for younger workers when many, as compared to few incentives, are present at work. We tested our hypotheses in a study with N = 756 workers at three measurement points. Results supported the main effect of i-e congruency on work motivation in the achievement and affiliation motive domains, and the moderation effects of age and incentives in the achievement motive domain. Implications for theories of motivation and age-sensitive counseling and coaching interventions are discussed

    Problems of Nonidentifiability and Alternative Solutions

    The bifactor model is a widely applied model to analyze general and specific abilities. Extensions of bifactor models additionally include criterion variables. In such extended bifactor models, the general and specific factors can be correlated with criterion variables. Moreover, the influence of general and specific factors on criterion variables can be scrutinized in latent multiple regression models that are built on bifactor measurement models. This study employs an extended bifactor model to predict mathematics and English grades by three facets of intelligence (number series, verbal analogies, and unfolding). We show that, if the observed variables do not differ in their loadings, extended bifactor models are not identified and not applicable. Moreover, we reveal that standard errors of regression weights in extended bifactor models can be very large and, thus, lead to invalid conclusions. A formal proof of the nonidentification is presented. Subsequently, we suggest alternative approaches for predicting criterion variables by general and specific factors. In particular, we illustrate how (1) composite ability factors can be defined in extended first-order factor models and (2) how bifactor(S-1) models can be applied. The differences between first-order factor models and bifactor(S-1) models for predicting criterion variables are discussed in detail and illustrated with the empirical example

    High Performers = Better Leaders? Evidence From 55 Years of Professional Soccer on the Validity of Performance-based Promotion to Leader Positions

    Promoting high-performing employees to leadership positions is a pervasive practice and has high face validity. However, little is known about the actual link between employee and subsequent leader performance as prior results are inconsistent. Given the prevalence of this performance-based promotion strategy, we conducted a study to address this inconsistency. To account for prior diverging results, we (a) competitively tested predictions from different theoretical perspectives (i.e., the performance requirements perspective, the follower-centric perspective, and the Theory of Expert Leadership), (b) considered possible changes in the predictive validity of this strategy over time, and (c) included job complexity as potential moderator of the link between employee and subsequent leader performance. In a high stakes context (i.e., the first German soccer league), we tested the predictive validity of employee performance for leader performance. Our results suggest a low validity of performance-based promotion, as we could not find evidence for a link between employee performance and leader performance—neither initially following the promotion nor over time, which is most in line with the performance requirements perspective. We, thus, caution against the (sole) application of performance-based promotion principles

    The influence of situational strength on the relation of personality and situational judgment test performance

    Get PDF
    Situational strength theory has been used as a theoretical underpinning of person–situation processes that are linked to job performance. Accordingly, the link between personality traits and job performance increases in weak situations. Building on this research, similar mechanisms have been proposed for simulation-based selection tools, such as Situational Judgment Tests (SJTs), to explain how these measures work as predictors of job performance. However, underlying processes of SJT performance are subject to debate with some scholars arguing in favor of context-independent processes while others maintain that situations play an essential role. This study (N = 707) examined whether the strength of situations in SJT items moderated the relation between personality and SJT performance. Results did not support the notion that personality is more strongly related to SJT performance when situations are weak. In fact, for some traits, the opposite may be true as more situational constraints led to an increase in the relation of extraversion, emotional stability, and SJT performance. The results add to an increasing body of research about psychological processes in SJTs. Limitations and implications for research and practice are discussed

    The importance of situation construal for situational judgment test performance

    Recent research challenges the importance of situation descriptions for situational judgment test (SJT) performance. This study contributes to resolving the ongoing debate on whether SJTs are situational measures, by incorporating findings on person × situation interactions into SJT research. Specifically, across three studies (NTotal = 1,239), we first tested whether situation construal (i.e., the individual perception of situations in SJTs) predicts responses to SJT items. Second, we assessed whether the relevance of situation construal for SJT performance depends on test elements (i.e., situation descriptions and response options) and item features (i.e., description‐dependent vs. description‐independent SJT items). Lastly, we determined whether situation construal has incremental validity for job‐related criteria over and above SJT performance. The results showed that, for most SJT items, situation construal significantly contributed to SJT performance, even if only response options were available. This was also true for SJT items that are significantly more difficult to solve when situation descriptions are omitted (i.e., description‐dependent SJT items). Finally, situation construal explained variance in relevant criteria over and above SJT performance. Despite recent efforts to reconceptualize SJTs, our results suggest that they can still be viewed as situational measures. However, situation descriptions may be less crucial for these underlying situational processes. Theoretical and practical implications are discussed
