A full-time PhD position at the Vrije Universiteit Amsterdam on the relations between personality, situations, and workaholism.

Personality, defined as a relatively stable psychological structure, is an important factor enabling the prediction of behavioral addictions and essential life outcomes. However, personality has been found to be only weakly to moderately related to workaholism. Consequently, studies of workaholism should account for additional - situational - factors to develop a better understanding of the connection between personality and workaholism. A basic assumption of this project is that traits will only be activated in specific situations, that is, only some situations will activate traits that are relevant for the development of workaholism. Furthermore, behavior regulation mechanisms may substantially contribute to the way workaholism develops.

Your duties
The current project aims to find, describe, and modify situations critical in activating personality traits that may induce workaholism. We will also investigate whether going through a workaholism-based burnout is related to changes in personality.

In this project, we define workaholism based on the Work Craving Theory (WCT; Wojdylo et al., 2013). This model is rooted in general mechanisms of behavioral addictions; it assumes that intensive working is the main strategy for work-addicted individuals to regulate their mood and to feel alive. Work-addicted individuals' high persistence and strong self-discipline when performing work-related activities may suggest that they adequately self-regulate behavior. However, intensive work appears to be mainly motivated by external factors and strong negative emotions, for instance, fear and anxiety, that cannot be attributed to adequate self-regulation. Notably, previous studies have failed to show what kind of situations activate the observed emotional states and behaviors of workaholics and whether the outcomes of workaholism can be considered consequences of the interaction between personality and situations.

We will conduct qualitative and quantitative studies; the latter will include cross-sectional and experience sampling studies. We also plan to employ ex-post-facto techniques. Utilizing open science practices is a default for this project.

The project will be supervised by Jacek Buczny and Reinout de Vries, both from the section Organizational Psychology at the Vrije Universiteit Amsterdam. For this project, we would like to fill a full-time 4-year PhD position. A strong background in statistics and methodology and an interest in personality and behavioral addictions is recommended. The PhD project is expected to result in a dissertation and two or more international peer-reviewed publications about behavioral addiction and health in the workplace. Research and conference travel expenses will be reimbursed. The PhD will join the Kurt Lewin Institute (KLI) and/or the Interuniversity Graduate School of Psychometrics and Sociometrics (IOPS) and will be expected to follow PhD-courses at the KLI/IOPS or at the VU to fulfil the VU Graduate School criteria to obtain a PhD. Furthermore, the PhD is offered an opportunity to yearly supervise a few master- and B-thesis students and to assist in teaching and/or other departmental activities (e.g., organizing colloquia or department outings).

• Research Master or Master in Psychology or closely related discipline (e.g., Behavioral Economics, Organizational Science);
• Research training and experience;
• Excellent knowledge of methodology and statistics;
• Excellent command of written and spoken English;
• Good knowledge of office (MS Office) and statistical software (R/RStudio).

An educational plan that includes attendance to courses and (international) meetings will be drafted.
