Turning Points in Professional Commitment Development: The Case of Novice Nurses.

We investigated the development of professional commitment over time and its relation to work experiences of novice nurses. We used a longitudinal mixed-method approach based on weekly reported quantitative commitment scores and qualitative descriptions of experiences. Specifically, we examined turning points in commitment trajectories and analyzed qualitative characteristics of the turning point. To determine a turning point, we firstly computed a smoothed trajectory for each individual and defined each point beyond the 95% interval of this smoothed trajectory as exceptional. Secondly, we explored whether the commitment development changed after an exceptional point with regard to the slope-valence or commitment strength. The sample consisted of 18 novice nurses. Two third of them revealed at least one turning point, thus the professional commitment development of novice nurses was characterized by peaks and dips that were followed by changes in the commitment development. The analysis showed that turning points followed by positive commitment development typically were characterized by positive experiences. These experiences often concerned relatedness or competence. Turning points followed by a negative development were not consistent: they could be positive, negative, or ambiguous experiences. Many of the negative experiences concerned negative organizational issues. We concluded that there is not a simple relation between commitment development and positive or negative characteristics of an experience. The context and underlying meaning of the experiences should be taken into account to interpret the commitment changes.
