The Mediating Effect of Stakeholder Trust between Total Quality Management Practices and the Sustainable Performance among Non-Profit Organizations in Saudi Arabia

Non-Profit Organizations are under increasing pressure to demonstrate accountability, service quality, and long-term value in response to evolving societal needs. While Total Quality Management (TQM) practices are known to enhance organizational performance, the mediating role of Stakeholder Trust in promoting Sustainability Performance remains underexplored. This study examines how TQM practices influence Sustainability Performance through Stakeholder Trust in 152 Saudi non-profit organizations. Data were collected via random sampling and analysed using Structural Equation Modelling with Smart PLS 4. Findings indicate that Stakeholder Trust significantly mediates the effect of TQM practices on Sustainability Performance, underscoring its essential role in organizational improvement. The study contributes empirically to the literature by demonstrating how quality management and trust-building mechanisms jointly enhance sustainable outcomes. Practical implications include strategies for nonprofit leaders and policymakers to strengthen governance, accountability, and both financial and non-financial sustainability in the sector.
