誰が組織内での発言をためらい，心理的安全性を低く感じるのか : 社会人調査モニターの性別・国籍・障害の有無に着目して

This study aims to explore how promotive and prohibitive voice, along with their antecedents, such as psychological safety, differ between minority employees (e.g., female employees, non-Japanese employees, and employees with disabilities) and non-minority employees. Research shows that demographic diversity in voice leads to various advantages. Conversely, research also shows that minority employees may have lower levels of voice and psychological safety. Thus, we hypothesized that the level of voice and psychological safety among Japanese minority employees would be lower than that among non-minority employees. An online survey was administered to 476 employees to measure their levels of voice and psychological safety. To determine the significant differences in voice and psychological safety between minority and non-minority employees, Welch's t-test was used. The results revealed that female employees reported a significantly lower level of prohibitive voice than male employees, and employees diagnosed with a current mental disorder reported a significantly lower level of prohibitive voice than those without such a diagnosis. In addition, individuals with a current or past mental disorder diagnosis reported significantly lower levels of psychological safety than those without any mental disorder diagnosis. These findings contribute to understanding the prevalence of low levels of voice and psychological safety among people with specific demographic characteristics.
