Two studies (n ¼ 273 and 254) used self-determination theory (SDT) to examine unemployed people's motivation both to search and not to search for a job. The self-regulation questionnaire format ) was used to assess participants' autonomous and controlled job-search motivation (the 'why' of job search) as well as their amotivation for searching. Additionally, both autonomous and controlled motivation for not searching (the 'why not' of job search) was assessed. Results provide validity for these five motivational constructs and indicate, in line with SDT, that the constructs predicted reports of search behaviour, affective experiences, and well-being. The addition of autonomous and controlled motivation for not searching contributed additional predictive power beyond the motivational constructs that focused only on searching.

Using self-determination theory, two studies found that holding an extrinsic, relative to an intrinsic, work value orientation was associated with less positive outcomes (i.e. less satisfaction with, dedication to and vitality while on the job) and more negative outcomes (i.e. higher emotional exhaustion, short-lived satisfaction after successful goal-attainment, and turn-over intention). These relations were not limited to job outcomes, but also emerged using indicators of employees' general mental health. Moreover, income level did not moderate these relations. Study 2 found that holding an extrinsic, relative to an intrinsic, work value orientation was detrimental to employees' job outcomes because these orientations thwarted the satisfaction of the basic psychological needs for autonomy, competence and relatedness at work.

Self-determination theory's distinction between extrinsic and intrinsic goal pursuits offers a possible explanation for ethnic and racial prejudice. Because extrinsic relative to intrinsic goal pursuits (E/I) stimulate interpersonal competition, they were expected to predict social dominance orientation (SDO), which, in turn, would predict racial and ethnic prejudice. Results of a first cross-sectional study showed that E/I goal pursuits are positively associated with prejudice and that SDO partially mediates this association. In a second longitudinal study, we replicated these results. In addition, however, we found evidence for a reciprocal relationship between E/I goal pursuit and SDO. Moreover, both E/I goal pursuit and SDO had an independent effect on increases in prejudice. Implications of these findings are discussed.

This two-wave (16-month lag) Belgian panel study is one of the first to test theory-driven hypotheses on the relations between job resources, work engagement, and actual turnover across time. The study focuses on three groups: stayers, workers who have obtained promotions (''promotion makers''), and external job movers. In line with the Job Demands-Resources model, we hypothesized normal crosslagged effects of job resources on work engagement for stayers. Based on broaden-and-build theory, a reversed causal effect of work engagement on job resources was predicted for the job changers. Additionally, we examined whether the changes in the job change groups matched the refuge hypothesis (that less engaged workers change to jobs providing more resources) or the positive gain hypothesis (that engaged workers get promoted to jobs having even more resources). The results partially supported our hypotheses. We found that low work engagement, low job autonomy, and low departmental resources predicted actual transfer to another company. Furthermore, for stayers we found positive effects of job autonomy on work engagement, but also reversed causal effects. For external movers and promotion makers the expected reversed causal effects of work engagement were found. The across time mean changes support the positive gain hypothesis for promotion makers, and the refuge hypothesis for external movers.
