Research goals and why the work was worth doing: Research of well-being and positive affect of workers have previous mainly been focused on a general level. These previous studies have not yet disentangled whether positive affect can be linked to task-by-task experience at work, or whether it mainly varies between different people with different types of work. The purpose of this study was to differentiate between the general level, task level, and type of employment in self-determination, meaningfulness of work and positive affect, thus contributing to the understanding of how to best assess well-being. The novelty and contribution of this study lies in the analysis strategy that allows for disentangling the effect that specific work tasks may have on workers' positive affect. Specifically, the use of multi-level modelling on the data gathered with the Day Reconstruction Method (DRM) allows us to describe relationships between positive affect, self-determination, and meaningfulness of work at both person and task level. Multilevel studies assessing the intrapersonal variability of experienced well-being on not only a day-level, but also a task level, are rare and much needed to better understand the dynamics of well-being during a workday.

Theoretical background: Researchers have connected positive affect – which represents momentary well-being experiences such as happiness, engagement, and inspiration – to high levels of general well-being and better health. High levels of positive affect is often attributed to higher levels of self-determination, and meaningfulness of work. Workers experiencing more self-determination and meaningfulness of work should experience more positive affect, and tasks experienced as more self-determined and meaningful should lead to more positive affect. Additionally, self-employed workers are suggested to have a more self-determined career choice in itself, and thus higher levels of positive affect.

Design/Methodology/Approach/Intervention: In this study we tested whether H1) workers experiencing more self-determination and meaningfulness of work report higher levels of positive affect, H2) tasks experienced as more self-determined and meaningful are related to more positive affect, and H3) self-employed workers experience stronger relationships of task level self-determination and meaningfulness with positive affect than employed workers. We used a sample of 175 high skilled self-employed and employed workers, who reported self-determination, meaningfulness of work and positive affect for a total of 560 tasks during a workday by the DRM. DRM facilitates access to momentary experiences stored in memory, providing reliable estimates of intensity and variations of affect during the day. First, we tested two separate multilevel multi-group confirmatory factor analysis (MCFA) models for momentary positive affect (outcome side of the model), as well as self-determination and meaningfulness of tasks (predictor side of the model), and then tested the models for measurement invariance. Since tasks were nested within individuals we fitted a bayesian structural equation model with random slopes with self-determination and meaningfulness of work and employment type as predictors and positive affect as an outcome variable.

Results obtained: Results indicated that workers experiencing more self-determination and meaningfulness of work reported more positive affect, that tasks experienced as more self-determined also elicited higher levels of positive affect, and that there was a small positive effect of self employment on positive affect. The self-determination and meaningfulness of tasks seem to be more important to positive affect than employment type. The relationship between self employment on positive affect have been assumed by earlier research, but our study is the first to test and show that this indeed may be the case. However, other factors such as self-determination might be more important to task level positive affect.

Limitations: We studied high-skilled worker, choosing this population facilitated comparison of groups of workers, as many background variables were similar, however, this does affect the generalizability of the results. As consequence, one limitation is that a fairly small sample. Further, we used DRM and a drawback of this method is that it is not in the moment assessment, but rather recorded after the tasks of the day. However, DRM still have practical benefits as it might elevate the response rate in contrast to in the moment reports, because it is difficult for the respondent to make pauses during their workday.

Research/Practical Implications: These findings may inform researchers on how to best assess well-being, and organizations on how to design work of workers to elevate positive affect and thus, well-being, and health. We have empirically confirmed the assumptions of a positive relationship between self employment and positive affect of previous studies, and that this relationship might be less important than other factors such as self-determination.

Originality/Value: The originality of this research lies in the multi-level structure of the method and analysis, as well as the comparison of groups of workers.

Objective Little is known about the relationship between quick returns (QR) - shift combinations that result in inter-shift rest periods <11 hours) and stress. The current study examined whether variations in the frequency of QR, both between and within individuals, were associated with changes in self-rated stress.

Methods A questionnaire was sent weekly to newly graduated nurses during the first 12 weeks of work. Stress was measured with four items from the Stress-Energy Questionnaire on a scale from 1 not at all to 5 very much [mean 2.65, standard deviation (SD) 1.08]. Shifts worked in the past week were reported and QR were identified by evening-morning shift combinations (mean 0.98, SD 0.90 per week). In total, 350 persons were included in the analysis (3556 observations). Data were analyzed with a multilevel residual dynamic structural equation model (RDSEM) using Bayesian estimation procedures.

Results There was no between-person effect of QR on stress averaged across measurement occasions (0.181, 95% CI -0.060-0.415). However, there was a small within-person effect of QR (0.031, 95% CI 0.001-0.062), meaning that more QR during a given week, compared to that person's average, was associated with an increase in their level of stress during that week.

Conclusions Nurses were likely to report increased stress during weeks in which they worked more QR. Intervention studies are needed to determine whether the relationship is causal.

Aim: This study aimed to identify profiles of working conditions to which nurses were exposed to over time and investigate how changes in working conditions relate to shiftworking and health.

Background: Previous studies rarely addressed the issue of working conditions development over long periods and the effects of such development on nurses' health.

Methods: Data from a national cohort of nurses in Sweden (N = 2936) were analysed using a person-centred analytical approach-latent profile and latent transition analysis.

Results: Nurses report better psychosocial working conditions as they progress into mid-career. Shiftworking nurses experience poorer working conditions than their dayworking counterparts and tend to move from shiftwork to daywork as they progress into mid-career. In mid-career, nurses in work environments characterized by low autonomy and support tend to report poorer health outcomes.

Conclusion: Current analyses suggest that shiftworking nurses are particularly in need of interventions that address poor work environments. Not only do they experience more negative psychosocial working conditions than their dayworking counterparts, but they do so while having to contend with demanding schedules. Implications for Nursing Management The findings highlight that organisational interventions should target different aspects of the work environment for nurses in diverse stages of their careers.

Theories of psychosocial working conditions assume an interaction of different work environment characteristics. Most studies detail various aspects of such interactions, while fewer investigate the comprehensive patterns of interrelated variables. This exploratory study distinguishes patterns of psychosocial working conditions, describes their characteristics, and investigates their change over 6 years. The working conditions of 1,744 high-skilled workers in Sweden, of a representative sample of the working population, were empirically classified into 4 distinct patterns: (a) the Supporting pattern with a very low workload, very low time pressure, medium learning opportunities, high creativity requirements, and very high autonomy; (b) the Constraining pattern with a very low workload, very low time pressure, low learning opportunities, medium creativity requirements, and very low autonomy; (c) the Demanding pattern with a high workload, high time pressure, medium learning opportunities, high creativity requirements, and very low autonomy; and (d) the Challenging pattern with a high workload, high time pressure, very high learning opportunities, very high creativity requirements, and very high autonomy. Importantly, these patterns were associated with significant differences in worker well-being. From an individual perspective, working conditions most often changed from patterns with a high workload and time pressure to patterns with lower levels of these demands. Over time, the prevalence of the Constraining pattern increased while that of the Challenging pattern decreased. To conclude, a person-centered approach broadens the understanding of the complex interplay between psychosocial working conditions and their longitudinal change, which can improve the tailoring of occupational health interventions.

Purpose - Self-employed workers typically report higher well-being levels than employees. The purpose of this paper is to examine the mechanisms that lead to differences in work engagement between self-employed and organizationally employed high-skilled workers. Design/methodology/approach - Self-employed and organizationally employed high-skilled workers (N = 167) were compared using a multigroup multilevel analysis. Participants assessed their job control (general level) and reported their work engagement during work tasks (task level) by means of the Day Reconstruction Method. Aspects of job control (autonomy, creativity, and learning opportunities) and task characteristics (social tasks and core work tasks) were contrasted for the two groups as predictors of work engagement. Findings - Self-employed workers reported higher levels of job control and work engagement than organizationally employed workers. In both groups, job control predicted work engagement. Employees with more opportunities to be creative and autonomous were more engaged at work. Self-employed workers were more engaged when they had more learning opportunities. On the task level, the self-employed were more engaged during core work tasks and social tasks. Practical implications - The findings suggest that self-employment is an effective way for high-skilled workers to increase the amount of job control available to them, and to improve their work engagement. From an intervention perspective, self-employed workers may benefit most from more learning opportunities, more social tasks, and more core work tasks. Organizationally employed workers may appreciate more autonomy and opportunities for creativity. Originality/value - This study contributes to a better understanding of the role that job control and task characteristics play in predicting the work engagement of high-skilled self-employed and organizationally employed workers.

Previous studies have linked positive emotions with creativity, but it remains unknown why creative activities may enhance positive emotions. We tested how creative tasks influence autonomous self-expression and task absorption, and whether this in turn increases positive emotions. Data from 478 participants were divided into four language samples (English, German, Italian, and Polish) and analyzed in a series of multigroup structural equation models. The indirect effects were replicated in all samples. Creative tasks enhanced positive emotions through an increase in autonomy. However, participants who solved creative tasks also reported lower task absorption, and this has hindered their experience of positive emotions. In total, a small increase of positive emotions was recorded for creative tasks in comparison to non-creative ones. We suggest that creative activities may support autonomous functioning and enhance positive emotions, given that participants will stay sufficiently focused on the task.

The purpose of this study is to investigate if a change in psychological well-being can result from engagement in creative activity. In an online experimental study participants will be randomly assigned to solve either a creative or a non-creative task. Their experience of completing the task will be compared with their average daily well-being level. Involvement in a creative task is expected to boost both positive feelings (hedonic well-being) and good functioning (eudaimonic well-being). Personal characteristics, such as a need for closure, and task features, e.g. difficulty level, will also be tested for their moderating effects.

Purpose: The affective space of human emotions is considered to be structured by two dimensions: the pleasure vs. displeasure continuum and the degree of arousal. Highly energetic positive states, such as engagement, are distinguished from more passive ones, such as satisfaction. Both can be considered indicators of employees’ well-being. The aim of this study was to investigate whether employees characterized by contrast levels of work centrality and turnover intention, differ with respect to feelings of engagement and satisfaction. We hypothesized that divergent attributes of those two emotions are linked to contrasting causes.

Design/Methodology: In order to test this assumption we conducted a study, in which 579 Swedish employees completed a questionnaire measuring positive feelings at work, intention to leave the company and work centrality.

Results: Multivariate analyses revealed that the feeling of satisfaction was negatively associated with decision of leaving the job. However, among employees expressing an intention to remain in the organization, highly engaged were primarily those, who considered work as central in their lives.

Limitations: Findings refer to a general, overall feelings. It is recommended to check whether differences between satisfaction and engagement hold also on a state level of emotions.

Research/Practical Implications: Satisfaction is a sign of reaching an acceptable level of what is expected from a job. However, results suggest that this is not enough to be engaged. Individuals have to highly value their work to feel engaged.

Originality/Value: This study explores the difference between two forms of employees’ well-being, which is often ignored in work psychology.
