Using and extending career construction theory (CCT), this study disentangled parallel and attenuating relationships between career adaptability and proactive career behaviours on both the interindividual and intraindividual levels. Using a large heterogeneous sample of working adults, univariate and bivariate latent growth curve analyses were conducted (three measurement points, 9‐month time span). On the one hand, career adaptability and proactive career behaviours showed positive relations of initial interindividual levels. Furthermore, intraindividual changes in career adaptability and proactive career behaviours were positively related, pointing towards a parallel development. On the other hand, as predicted, the initial level of career adaptability was negatively related to the slope of developmental trajectories of proactive career behaviours. In other words, because the average growth rate for proactive career behaviours was negative, this means that individuals with higher initial career adaptability showed stronger decreases in proactive career behaviours. Finally, only the intraindividual developments of career adaptability, but not of proactive career behaviours, positively predicted higher levels of career satisfaction. These findings point towards diverse developmental relationships between career adaptability and proactive career behaviours. Results are discussed against the background of CCT and successful career development.

职业适应性和积极主动的职业行为如何随着时间而相互关联？个体间调查

使用并扩展职业建设理论（CCT），本研究在个体和个体内的水平上解开了职业适应性与主动职业行为之间的平行关系，并减弱了它们之间的关系。使用大量的异类成年劳动者样本，进行了单变量和双变量潜在生长曲线分析（三个测量点，9个月的时间跨度）。一方面，职业适应性和积极主动的职业行为表现出初始个体之间的正相关关系。此外，职业适应性和积极主动的职业行为的个体差异正相关，指向平行发展。另一方面，正如预期的那样，职业适应性的初始水平与积极职业行为的发展轨迹的斜率负相关。换句话说，因为积极的职业行为的平均增长率为负，这意味着具有较高初始职业适应能力的个人在积极的职业行为中表现出更大的下降。最后，只有职业适应性的个体发展而不是积极主动的职业行为才能积极预测更高的职业满意度。这些发现指出了职业适应性和积极的职业行为之间的不同发展关系。在CCT和成功的职业发展背景下讨论了结果。这意味着具有较高初始职业适应能力的个人在积极主动的职业行为中表现出更大的下降。最后，只有职业适应性的个体发展而不是积极主动的职业行为才能积极预测更高的职业满意度。这些发现指出了职业适应性和积极的职业行为之间的不同发展关系。在CCT和成功的职业发展背景下讨论了结果。这意味着具有较高初始职业适应能力的个人在积极主动的职业行为中表现出更大的下降。最后，只有职业适应性的个体发展而不是积极主动的职业行为才能积极预测更高的职业满意度。这些发现指出了职业适应性和积极的职业行为之间的不同发展关系。在CCT和成功的职业发展背景下讨论了结果。这些发现指出了职业适应性和积极的职业行为之间的不同发展关系。在CCT和成功的职业发展背景下讨论了结果。这些发现指出了职业适应性和积极的职业行为之间的不同发展关系。在CCT和成功的职业发展背景下讨论了结果。
