Aiming at exploring the influence of quality management systems (QMS) in staff’s work engagement and psychological empowerment in private institutions of social solidarity (IPSSs), this study performs a comparative analysis between institutions with and without an ISO 9001-based QMS. Data were collected through questionnaires applied to employees from two IPSSs with a certified QMS and two IPSSs without a QMS. Findings show that although employees’ perception about psychological empowerment and engagement are generally higher in IPSS with an ISO 9001-based QMS, these differences are not statistically significant. Nevertheless, in what empowerment concerns, the perception of employees with leading role in IPSS with an ISO 9001-based QMS is significantly greater than the perception of those in IPSS without a QMS. To our knowledge, no previous study has investigated the influence of ISO 9001-based QMS in employees’ work-related attitudes in the third sector; these results contribute thus to new insights concerning a clearly under-researched field.

旨在探索质量管理体系 (QMS) 对私营社会团结机构 (IPSS) 员工工作投入和心理赋权的影响，本研究对有和没有基于 ISO 9001 的 QMS 的机构进行了比较分析。数据是通过对两个具有认证 QMS 的 IPSS 和两个没有 QMS 的 IPSS 的员工进行的问卷调查收集的。调查结果表明，虽然员工对心理授权和参与的看法在采用基于 ISO 9001 的 QMS 的 IPSS 中普遍较高，但这些差异在统计上并不显着。然而，在授权关注的问题上，在 IPSS 中具有基于 ISO 9001 的 QMS 的领导角色的员工的看法明显大于在 IPSS 中没有 QMS 的员工的看法。据我们所知，以前没有研究调查过基于 ISO 9001 的 QMS 对第三部门员工工作相关态度的影响；因此，这些结果有助于对一个明显研究不足的领域产生新的见解。
