The current study investigated the impact of adding the Suicide Status Form (SSF) to a suicide-focused group therapy for veterans recently discharged from an inpatient psychiatry setting. A sample of 141 veterans was enrolled and randomized into a Usual Assessment Group Therapy or SSF-Assessment Group Therapy. Participants completed interviews at baseline, 1, and 3 months. No significant differences were observed between groups regarding group attendance (IRR = 1.01, Std. Err = 0.08, 95% CI = 0.87, 1.18) or client satisfaction (β = 0.23, Std. Err = 0.66, p = 0.73, d = -.25). No main effects were observed across the study on secondary outcomes of interest for suicidal ideation and overall symptom distress, although participants in both treatment conditions reported significant improvements on these outcomes over the course of the study. Patients in the Usual Assessment Group Therapy demonstrated greater reductions in overall symptom distress across the 3-month follow-up window (β = 6.08, Std. Err = 2.04, p = 0.003; f = 0.05). Follow-up path analyses revealed that more frequent session attendance was significantly related to less suicidal ideation at 1-month, higher working alliance between individual members and group facilitators was associated with greater suicidal ideation at 1-month, and higher group cohesion among group members at 1-month was significantly associated with less thwarted belongingness at 1-month. Although the SSF did not improve the impact of an existing suicide-focused group therapy, the study findings support future research on group treatments for suicidal veterans.

Past suicidal behaviors are among the strongest and most consistent predictors of eventual suicide and may be particularly salient in military suicide. The current study compared characteristics of suicide attempts in veterans (N = 746) and active-duty service members (N = 1,013) receiving treatment for acute suicide risk. Baseline data from six randomized controlled trials were pooled and analyzed using robust regression. Service members had greater odds of having attempted suicide relative to veterans, though there were no differences in number of attempts made. Service members also had higher rates of premilitary suicide attempts and nonsuicidal self-injury (NSSI). Veterans disproportionately attempted suicide by means of overdose. In veterans, combat deployment was associated with lower odds of lifetime suicide attempt, while history of NSSI was associated with greater attempt odds. Neither was significantly associated with lifetime suicide attempt in service members. Implications for suicide assessment and treatment are discussed.

Findings may inform clinical strategies for conceptualizing and targeting factors associated with suicidal risk.
