Purpose

This paper aims to examine the impact of adverse personality traits (alexithymia, social inhibition, negative affectivity) and supervisor knowledge hiding on individual knowledge hiding. This study also explores the moderating role of positive affectivity.

Design/methodology/approach

Partial least squares path modeling and data collected from 518 Polish employees with higher education and extensive professional experience recruited via an Ariadna survey panel were used to test the research hypotheses.

Findings

Two dimensions of alexithymia were considered: difficulty identifying feelings (DIF) and difficulty describing feelings (DDF). DIF has a direct impact on individual hiding, whereas DDF has an indirect impact, via social inhibition. Negative affectivity is a predictor of social inhibition, which enhances knowledge hiding. Positive affectivity slightly weakens the positive and strong effect of supervisor knowledge hiding on subordinate knowledge hiding.

Practical implications

Because alexithymia, social inhibition and negative affectivity may predispose employees to knowledge hiding, managers should identify these personality traits among job applicants and hired employees to make appropriate employment decisions. Moreover, managers should be aware that hiding knowledge by a supervisor may be imitated by subordinates.

Originality/value

Based on conservation of resources theory, this study investigates previously unexplored relationships among alexithymia, social inhibition, affectivity and knowledge hiding.

述情障碍、社会抑制、情感和知识隐藏

目的

本文旨在检验不良人格特质（述情障碍、社交抑制、消极情感）和主管知识隐藏对个体知识隐藏的影响。本研究还探讨了积极情感的调节作用。

设计/方法/途径

偏最小二乘路径建模和数据是通过 Ariadna 调查小组招募的具有高等教育和丰富专业经验的 518 名波兰员工收集的，用于检验研究假设。

发现

述情障碍的两个维度被考虑：难以识别感受（DIF）和难以描述感受（DDF）。DIF 对个人隐藏有直接影响，而 DDF 通过社会抑制有间接影响。消极情感是社会抑制的预测因子，它增强了知识隐藏。积极情感略微削弱了主管知识隐藏对下属知识隐藏的正向和强烈影响。

实际影响

由于述情障碍、社交抑制和消极情感可能使员工容易隐藏知识，因此管理者应该在求职者和雇用员工中识别这些人格特质，以做出适当的雇佣决定。此外，管理者应该意识到主管隐藏知识可能会被下属模仿。

原创性/价值

基于资源保护理论，本研究调查了以前未探索过的述情障碍、社会抑制、情感和知识隐藏之间的关系。
