Psychoeducational groups have been used to address many health needs. Yet, there are few such options available for people who have attempted suicide. This study presents preliminary findings from an open trial of Eclipse, an 8-week closed, psychoeducational group for people who have attempted suicide. It examined the effectiveness of the Eclipse program in reducing suicidal ideation, depressive symptoms, perceived burdensomeness and thwarted belongingness, and increasing resilience and help-seeking. Results showed statistically significant improvements in depressive symptoms, perceived burdensomeness, resilience and help-seeking from baseline (T1) to immediate post-test (T2), and in perceived burdensomeness from
T1 to 1-month follow-up (T3). A pervasiveness analysis showed that over half of the participants reported improvements in key study outcomes, respectively, as a result of participating in the Eclipse group. Psychoeducational support groups could provide broad application for those who have previously attempted suicide in decreasing severity of suicidal thinking by reductions in depressive symptoms, burdensomeness, and thwarted belongingness.
