abstract="The link between suicidality and social disconnection is well-established. We explored possible mechanisms that may account for this link using a positive and negative valence systems framework in a clinical sample with and without suicidality (i.e., suicidal ideation and/or behaviors in the past month). Participants (N = 228) interacted with a trained confederate during a controlled conversation task designed to generate social affiliation. Participant-rated positive affect (PA) and negative affect (NA) were collected during the task (baseline, anticipation, post). Participant-rated desire for future interaction was collected after the task. We tested if (1) groups with (n = 82) and without (n = 146) suicidality differed in affect during the task and (2) whether affect accounted for the link between suicidality and desire for future interaction. <br><br>RESULTS revealed that groups differed in PA, but not NA, throughout the task. Participants with suicidality reported no significant changes in PA over the task (ps > .05); and, experienced less PA at post-task compared to those without (p = .003, d = 0.38) whereas participants without suicidality reported increased PA at post-task compared to baseline and anticipation of the task, ps < .001. Mediation analysis suggested blunted post-task PA accounted for the relationship between suicidality and less desire for future interaction, 95%CI [-2.59,-0.51]. Diminished PA reactivity during social affiliation opportunities may help explain the link between suicidality and social disconnection. Preliminary findings highlight PA as a potential mechanistic target for improving social connection for individuals at risk for suicide, though prospective and experimental research is needed.<p /> <p>Language: en</p>",
