A step away from impaired well-being: a latent growth curve analysis of an intervention with activity trackers among employees

ABSTRACT

The present study evaluated the effectiveness of a workplace intervention combining activity trackers (behavioural approach) with an online coach (cognitive approach) in order to increase employees’ number of steps and improve their impaired well-being (i.e., emotional strain and negative affect). To analyse the intervention’s effectiveness, the study applied latent growth curve modelling. Moreover, we tested whether work-related and personal resources (i.e., job control and self-efficacy) moderated the intervention’s effectiveness and whether an increase in number of steps was associated with an improvement in impaired well-being. During the intervention, data were collected at six measurement points from 108 mainly low active employees. The results revealed that employees increased their number of steps until the second intervention week; this increase was not moderated by job control or self-efficacy. Moreover, the intervention was effective in decreasing emotional strain and negative affect over the course of the intervention. Further analyses showed that the increase in number of steps was related to the decrease in negative affect, whereas no such association was found for the increase in number of steps and the decrease in emotional strain. In conclusion, the findings showed that our intervention was effective in improving physical activity and impaired well-being among employees.     

Investigating curvilinear relationships of explicit and implicit aggression with workplace outcomes

ABSTRACT

Although previous research has demonstrated the value of integrating explicit and implicit measures of aggression for predicting workplace outcomes, such investigations only examined linear and interactive effects. Here we examine nonlinear (i.e., curvilinear) effects of explicit and implicit aggression, which revealed subtleties in the manifestation of aggression. We found significant curvilinear effects of explicit aggression on peer-reported deviance (property deviance, production deviance, and personal aggression). In each case, deviance was lowest when explicit aggression was low, and increased as explicit aggression increased. However, production and property deviance decreased at elevated levels of explicit aggression. In contrast, for disciplinary actions, explicit and implicit aggression interacted, but there was also a curvilinear effect of implicit aggression. This pattern led to discipline being highest when explicit and implicit aggression were very incongruent, but being quite low when they were congruent. The results show that examining nonlinear effects with respect to explicit and implicit aggression can reveal unexpected relationships when predicting peer-reported criteria or organizational personnel data. Propositions for future research on the relationship of personality to workplace outcomes are presented deriving from the trait activation model, and implications for workplace interventions are discussed.
