Managing pain presents significant challenges, including the need to address multiple biopsychosocial factors and the difficulty in delivering evidence-based treatments. Digital health technologies, such as conversational agents, offer the potential for personalised and accessible pain management. However, the characteristics and effectiveness of these interventions are not yet fully understood. This scoping review aims to comprehensively evaluate the applications and effectiveness of conversational agents in supporting pain management in adults (i.e., healthy individuals at risk of developing pain, individuals currently experiencing pain and healthcare providers or students involved in managing pain conditions).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Searches were systematically conducted across six databases—MEDLINE PubMed, ACM Digital Library, CINAHL, Embase, PsycINFO, Cochrane CENTRAL—and five trial registries from inception.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Twenty-eight studies were included, focusing on capturing health information (&lt;i&gt;n&lt;/i&gt; = 8), providing emotional support (&lt;i&gt;n&lt;/i&gt; = 7), facilitating adherence to self-management exercises (&lt;i&gt;n&lt;/i&gt; = 6), delivering psychological treatment (&lt;i&gt;n&lt;/i&gt; = 5), offering organisational support (&lt;i&gt;n&lt;/i&gt; = 1) and educating healthcare providers (&lt;i&gt;n&lt;/i&gt; = 1).
