ABSTRACT
BACKGROUND: Few investigations of patient perceptions of suicide prevention interventions exist, limiting our understanding of the processes and components of treatment that may be engaging and effective for high suicide-risk patients. AIMS: Building on promising quantitative data that showed that adjunct mindfulness-based cognitive therapy to prevent suicidal behavior (MBCT-S) reduced suicidal thinking and depression among high suicide-risk patients, we subjected MBCT-S to qualitative inspection by patient participants. METHOD: Data were provided by 15 patients who completed MBCT-S during a focus group and/or via a survey. Qualitative data were coded using thematic analysis. Themes were summarized using descriptive analysis. RESULTS: Most patients viewed the intervention as acceptable and feasible. Patients attributed MBCT-S treatment engagement and clinical improvement to improved emotion regulation. A minority of patients indicated that factors related to the group treatment modality were helpful. A small percentage of patients found that aspects of the treatment increased emotional distress and triggered suicidal thinking. These experiences, however, were described as fleeting and were not linked to suicidal behavior. LIMITATIONS: The sample size was small. CONCLUSION: Information gathered from this study may assist in refining MBCT-S and treatments to prevent suicidal behavior among high suicide-risk patients generally.

OBJECTIVE: To test changes to cognitive functioning among high-suicide risk outpatients participating in an adjunct mindfulness-based intervention combining mindfulness-based cognitive therapy and safety planning (MBCT-S). DESIGN: Ten outpatients with a 6-month history of suicide attempt or active suicidal ideation plus suicidal ideation at study entry received 9 weeks of adjunct group-based MBCT-S. Executive attention, sustained attention, visual memory, and semantic memory encoding were measured by neuropsychological assessment. Rumination, mindfulness, cognitive reactivity (defined as the tendency towards depressogenic information processing and thought content in response to mild mood deterioration), and self-compassion were assessed using self-report measures. Changes in pre- to post-treatment functioning on these constructs were analyzed by using dependent t-tests. Where significant improvements were found, correlations between changes to cognitive functioning and depression and suicidal ideation during treatment were calculated. RESULTS: Executive attention improved with MBCT-S in high-suicide risk outpatients (Stroop interference effect = 0.39 [standard deviation (SD), 27] at baseline and 0.27 (SD, 0.15) at post-treatment, t[9] = 2.35, p = 0.04, d = 0.75). One mindfulness skill, acting with awareness, increased with MBCT-S (average change in Five Facet Mindfulness Questionnaire-acting with awareness subscale score with treatment, 3.3 [SD, 3.0], t[9] = 3.46, p < 0.01, d = 1.1). Self-reported rumination and cognitive reactivity to suicidality and hopelessness decreased among participants (Ruminative Responses Brooding subscale score change, -3.4 [SD, 1.1], t[9] = 10, p < 0.001, d = 3.2; Leiden Index of Depression Sensitivity-Revised-Hopelessness/Suicidality subscale score change, -3 [SD, 2.7], t[9] = 3.56, p < 0.01, d = 1.1). None of these changes were related to improvements in depression or reductions in suicidal ideation during treatment. CONCLUSIONS: Findings from the present pilot study suggest that treatment with MBCT-S may improve cognitive deficits specific to suicide ideators and attempters among depressed patients. Future controlled trials using follow-up assessments are needed to determine the specificity of these improvements in cognitive functioning to MBCT-S and their durability and to formally test whether the observed improvements in cognitive functioning explain MBCT-S treatment gains.

Identification of biological indicators of suicide risk is important given advantages of biomarker-based models. Decreased high frequency heart rate variability (HF HRV) may be a biomarker of suicide risk. The aim of this research was to determine whether HF HRV differs between suicide attempters and non-attempters. Using the Trier Social Stress Test (TSST), we compared HF HRV between females with and without a history of suicide attempt, all with a lifetime diagnosis of a mood disorder. To investigate a potential mechanism explaining association between HF HRV and suicide, we examined the association between self-reported anger and HF HRV. Results of an Area under the Curve (AUC) analysis showed attempters had a lower cumulative HF HRV during the TSST than non-attempters. In addition, while there was no difference in self-reported anger at baseline, the increase in anger was greater in attempters, and negatively associated with HF HRV. Results suggest that suicide attempters have a reduced capacity to regulate their response to stress, and that reduced capacity to regulate anger may be a mechanism through which decreased HF HRV can lead to an increase in suicide risk. Our results have implications for the prevention of suicidal behavior in at-risk populations.

This article describes the rationale for using mindfulness-based interventions (MBIs) to prevent suicidal behavior in high suicide-risk individuals. A narrative review of studies testing the feasibility of MBIs with individuals at risk for suicidal behavior and the effectiveness of MBIs for reducing suicidality was conducted. Studies testing the effectiveness of MBIs for reducing deficits specific to suicide attempters among depressed individuals were also reviewed as were studies examining moderators of MBI treatment adherence and effectiveness to the extent that these might suggest possible limitations to using MBIs with high suicide-risk individuals. Findings from the handful of available studies support targeting suicidal ideation with MBI. Additional studies show deficits associated with suicide attempt, namely attentional dyscontrol, problem solving deficits, and abnormal stress response, are improved by MBI and thus strengthen the rationale for using MBIs with high suicide-risk individuals.
