<p>This study investigates how role ambiguity affects the performance of event volunteers, particularly in charity sport events. </p>
<p>The research explores the roles of social exchange qualities, such as team-member exchange (TMX) and leader-member exchange (LMX), in mitigating the negative effects of role ambiguity on job performance.<br>
Data were collected from volunteers at charity sport events in the U.S. between 2019 and 2021.</p>
<p>Key findings include:</p>
<ol>
<li>Role ambiguity negatively impacts volunteer job performance.</li>
<li>High-quality interactions with team members (TMX) and leaders (LMX) help reduce role ambiguity, thereby improving job performance.</li>
<li>Gender moderates the relationship between role ambiguity and job performance, with male volunteers being more affected by role ambiguity than female volunteers.</li>
</ol>
<p>The study suggests that enhancing social exchanges among volunteers and providing clear role definitions can improve volunteer performance.</p>
<p>Practical recommendations include using social media for team building and providing clear communication and feedback to volunteers. <br>
The research highlights the importance of addressing role ambiguity to support volunteer effectiveness and satisfaction.<br>
