Abstract
The overall goal of the present thesis is to explore and understand the dynamic interplay between personality and work. Chapter two presents a state of the science review of short- term personality expression; termed states, as investigated in the work context. The chapter provides a substantive overview of theoretical perspectives, summarises the empirical contributions to the field and methodological approaches taken. It was found that most investigations had either explored the impact of personality states on dynamic work- outcomes, such as performance, or the influence of work factors on the expression of key personality states. This chapter concludes with directions for future research based on the trends and omissions as highlighted within the review.
Chapter three empirically examines the dynamic patterns of personality states in response to the onset of the COVID-19 pandemic and in relation to employment status. Drawing upon Whole Trait Theory, data was captured using a two-week daily diary methodological design. Using growth curve modelling, negative trajectories for extraversion and agreeableness were found, while a positive growth trajectory was identified for neuroticism. Moreover, it was identified that those who remained in work during this time had significantly higher slopes for states of extraversion and conscientiousness, suggesting the continuation of work acted as a protective mechanism for state personality developments.
The final chapter draws upon Whole Trait Theory and the DATA Model to examine the influence of work factors on personality development over a three-month timespan. Analysis revealed that the constructs of personal accomplishment and organisational commitment dynamically interacted with extraversion, agreeableness, and conscientiousness, as hypothesised. Moreover, baseline levels of personal accomplishment were positively associated with developments in conscientiousness, responsibility, and trust over time. In contrast, the baseline level of trait productivity was positively related to changes in personal accomplishment, suggesting a dynamic, intertwined relationship between personality and work.
