This study seeks to achieve a dynamic understanding of nursing students' engagement trajectories, of the predictive role of their levels of harmonious passion, obsessive passion, exposure to challenge and hindrance demands, and perceptions of institutional support in relation to their engagement trajectories. We also consider the implications of these trajectories for a variety of outcomes related to students' attitudes (i.e., dropout intentions and program satisfaction), psychological health (i.e., negative affect and life satisfaction), and behaviors (i.e., performance and absenteeism). A sample of 2515 first-year nursing students were surveyed five times, with intervals of one month, over a four-month period during the first semester of their program. Our results revealed four profiles of students presenting High and Stable, Moderate and Decreasing, Low and Decreasing, and Moderate and Stable engagement trajectories. Harmonious and obsessive passion, challenge and hindrance demands, and institutional support were associated with these trajectories in a way that mainly supported our expectations. Trajectories characterized by lower levels of engagement were associated with higher levels of negative affect and absenteeism, and with lower levels of performance, program satisfaction, and life satisfaction. Conversely, trajectories characterized by higher levels of engagement were associated with lower levels of dropout intentions and higher levels of performance.

本研究旨在动态了解护生的参与轨迹、他们的和谐热情、强迫热情、面临挑战和阻碍需求的水平的预测作用，以及与其参与轨迹相关的机构支持的看法。我们还考虑这些轨迹对与学生态度（即辍学意图和项目满意度）、心理健康相关的各种结果的影响（即负面影响和生活满意度）和行为（即绩效和缺勤）。在课程第一学期的四个月内，对 2515 名一年级护理学生进行了五次调查，调查间隔为一个月。我们的结果显示，学生的四种情况呈现出高且稳定、中等和下降、低和下降以及中等和稳定的参与轨迹。和谐而执着的激情、挑战和阻碍的要求以及机构的支持与这些轨迹相关联，主要支持我们的期望。以较低参与度为特征的轨迹与较高水平的负面情绪和缺勤有关，并且与较低水平的绩效、项目满意度和生活满意度相关。反过来，
