This study documents the influence of both pre- and post-entry factors on newcomer socialization. Using time-lagged survey data from 137 new employees from private sector organizations in Japan, our empirical analyses showed that newcomers' pre-entry career maturity was significantly related to their post-entry adjustment outcomes through person-organization (P-O) fit perceptions at entry. Career maturity was also significantly and positively related to pre-entry job search effort, as well as to P-O fit at entry. Furthermore, the results indicated that the effectiveness of supervisor and coworker support for enhancing newcomer adjustment varied depending on the level of P-O fit perception at entry. The theoretical and practical implications of these findings are discussed, and directions for future research are suggested.

迈向新人社会化过程模型：整合入职前和入职后因素进行新人调整

本研究记录了进入前和进入后因素对新移民社会化的影响。使用来自日本私营部门组织的 137 名新员工的时滞调查数据，我们的实证分析表明，新员工的入职前职业成熟度与入职后的个人-组织 (PO) 契合度认知显着相关. 职业成熟度也与入职前的求职努力以及入职时的 PO 适合度显着正相关。此外，结果表明，主管和同事支持增强新人调整的有效性取决于入职时 PO 适合度感知的水平。讨论了这些发现的理论和实践意义，并提出了未来研究的方向。
