Objective: To examine the safety and efficacy of a brief cognitive dual-task (using eye movements) add-on module to treatment as usual (TAU) in reducing the severity and frequency of intrusive suicidal mental images and suicidal ideation. Method: We conducted a single-blind, parallel multicenter randomized trial (No. NTR7563) among adult psychiatric outpatients (N = 91; Mage = 34.4, SD = 13.54; 68% female) with elevated depressive symptoms and experiencing distressing suicidal intrusions in the Netherlands. Primary outcome was the severity (Suicidal Intrusions Attributes Scale) and frequency (Clinical Interview for Suicidal Intrusions) of suicidal mental imagery intrusions at 1-week posttreatment and 3-month follow-up. Primary analysis was intention-to-treat. Results: Between November 27, 2018 and September 13, 2021, 91 patients were included and randomly assigned to intervention group (Cognitive Dual Task Add-on + TAU) (n = 46) or TAU-only (n = 45). Cognitive Dual Task Add-on + TAU had greater reductions in severity (mean difference, −15.50, 95% CI [23.81, −7.19]; p <.001, d = 0.60), and frequency (geometric mean difference, 0.47, 95% CI [0.29, 0.79]; p =.004) of suicidal intrusions over time than TAU-alone. Cognitive Dual Task Add-on + TAU patients also showed lower suicidal ideation over time (p =.008, d = 0.42). There were no significant group differences in reductions in depressive symptoms, rumination, or hopelessness. Four serious adverse events occurred (three Cognitive Dual Task Add-on + TAU; one TAU-only); all unlikely attributable to intervention/trial. Conclusions: Findings provide support for the effectiveness of adding a cognitive dual-task module to the treatment of psychiatric outpatients with elevated depressive symptoms in reducing suicidal intrusions and ideation and can be executed safely. What is the public health significance of this article?: This study strongly suggests that adding a brief cognitive dual-task module to treatment as usual is efficacious in reducing suicidal intrusions and suicidal ideation in psychiatric outpatients with elevated depressive symptoms. This study highlights the importance of targeting distressing intrusive suicidal mental images as an important, novel approach in suicide prevention strategies. [ABSTRACT FROM AUTHOR]

Background: Twice weekly sessions of cognitive behavioral therapy (CBT) and interpersonal psychotherapy (IPT) for major depressive disorder (MDD) lead to less drop-out and quicker and better response compared to once weekly sessions at posttreatment, but it is unclear whether these effects hold over the long run. Aims: Compare the effects of twice weekly v. weekly sessions of CBT and IPT for depression up to 24 months since the start of treatment. Methods: Using a 2 × 2 factorial design, this multicentre study randomized 200 adults with MDD to once or twice weekly sessions of CBT or IPT over 16–24 weeks, up to a maximum of 20 sessions. Main outcome measures were depression severity, measured with the Beck Depression Inventory-II and the Longitudinal Interval Follow-up Evaluation. Intention-to-treat analyses were conducted. Results: Compared with patients who received once weekly sessions, patients who received twice weekly sessions showed a significant decrease in depressive symptoms up through month 9, but this effect was no longer apparent at month 24. Patients who received CBT showed a significantly larger decrease in depressive symptoms up to month 24 compared to patients who received IPT, but the between-group effect size at month 24 was small. No differential effects between session frequencies or treatment modalities were found in response or relapse rates. Conclusions: Although a higher session frequency leads to better outcomes in the acute phase of treatment, the difference in depression severity dissipated over time and there was no significant difference in relapse.
