Randomized Controlled Trial of a Brief Mindfulness-Based Intervention for Suicidal Ideation Among Veterans.

INTRODUCTION: This study was a preliminary evaluation of a manualized, brief mindfulness-based intervention (MB-SI) for veterans with suicidal ideation (SI), admitted into an inpatient psychiatric unit (IPU). MATERIALS AND METHODS: A randomized, controlled pilot study of 20 veterans aged 18-70 years with SI, admitted into a psychiatric unit, assigned to treatment as usual (TAU) or MB-SI groups. Outcome data were collected at three time points: preintervention (beginning of first session), postintervention (end of last session), and 1-month postintervention. Primary outcomes were safety and feasibility. Secondary outcome measures were SI and behavior, mindfulness state and trait, cognitive reappraisal, and emotion regulation. Additionally, psychiatric and emergency department admissions were examined. Data analysis included Generalized Linear Models, Wilcoxon Signed-Rank, Mann-Whitney U, and Fisher's exact tests for secondary outcomes. RESULTS: Mindfulness-based intervention for suicidal ideation was feasible to implement on an IPU, and there were no associated adverse effects. Mindfulness-based intervention for suicidal ideation participants experienced statistically significant increase in Toronto Mindfulness Scale curiosity scores 1-month postintervention compared to preintervention and greater Toronto Mindfulness Scale decentering scores 1-month postintervention compared to TAU. Emotion Regulation Questionnaire Reappraisal scores significantly increased for the MB-SI group and significantly decreased for TAU over time. IPU and emergency department admissions were not statistically different between groups or over time. Both TAU and MB-SI participants experienced a significant reduction in Columbia-Suicide Severity Rating Scale-SI scores after the intervention. MB-SI participants experienced a higher increase in Five-Facet Mindfulness Questionnaire scores postintervention compared to TAU. CONCLUSIONS: Mindfulness-based intervention for suicidal ideation is feasible and safe to implement among veterans during an inpatient psychiatric admission with SI, as it is not associated with increased SI or adverse effects. Preliminary evidence suggests that MB-SI increases veterans' propensity to view experiences with curiosity while disengaging from experience without emotional overreaction. Further, more rigorous research is warranted to determine efficacy of MB-SI. TRIAL REGISTRATION: The clinicaltrials.gov registration number is NCT04099173 and dates are July 16, 2019 (initial release) and February 24, 2022 (most recent update).

Mindfulness-based Therapeutic Sailing for Veterans With Psychiatric and Substance Use Disorders.

INTRODUCTION: Complementary interventions have the potential to enhance treatment engagement and/or response among veterans with psychiatric disorders and/or substance use disorders (SUDs). Mindfulness-based therapeutic sailing (MBTS) is a novel three-session, complementary intervention, which combines nature exposure via recreational sailing and mindfulness training. It was developed specifically to augment both treatment response and engagement among veterans with psychiatric disorders or SUDs. The study reports a follow-up investigation of a version of MBTS modified based upon a previous initial pilot study. MATERIALS AND METHODS: This is an institutional review board-approved study of 25 veterans, 23 males and 2 females, who participated in MBTS along with a diagnosis-, gender-, and age-matched control group. All participants had at least one psychiatric disorder or SUD and most (92%) had two or more conditions, with the most common being any SUD (76%) and PTSD (72%). Instruments used to evaluate within-subjects pre- to post-intervention psychological changes were the Acceptance and Action Questionnaire II (AAQII), the Toronto Mindfulness Scale (TMS), and the Five Facet Mindfulness Questionnaire (FFMQ). The Physical Activity Enjoyment Scale (PACES) was administered to evaluate how much the participants enjoyed the intervention. Outcome measures were collected for 1-year pre-intervention and 1-year post-intervention for between-subject analyses. These were numbers of medical and psychiatric hospitalizations, emergency department visits, mental health (MH) and substance abuse treatment visits, and MH and substance abuse treatment failed appointments. Data analysis consisted of using paired, two-tailed t-tests on psychological instrument results, Poisson regression on discrete outcome measures, and chi-square test of independence on demographic factors. RESULTS: Within-subjects comparisons revealed significant mean pre- to post-intervention increases in AAQII (P = .04) and TMS scores (P = .009). The FFMQ scores increased but the change was nonsignificant (P = .12). The PACES scores were high for all sessions, indicating enjoyment of the intervention by participants. Although the coefficient was nonsignificant, Poisson regression uncovered reduction in substance abuse treatment visits post-intervention. There were no significant differences for the other variables. For demographic factors, the differences between intervention and control groups were not statistically significant. CONCLUSIONS: The MBTS is associated with increases in psychological flexibility (AAQII) and state mindfulness (TMS). The intervention was perceived as pleasurable by participants (PACES) and is potentially associated with decreased utilization of substance use treatment services. These results must be considered as preliminary; however, these finding corroborate results from a previous pilot study and indicate that MBTS holds promise as a complementary intervention that could result in enhanced treatment engagement and/or outcomes for the population studied. A randomized controlled trial of MBTS is warranted. Further, the model of a three-session intervention combining mindfulness training with nature exposure could be adapted for other types of nature exposure, such as hiking or snowshoeing or other complementary interventions including equine-assisted activities and therapies.

Mindfulness Training plus Nature Exposure for Veterans with Psychiatric and Substance Use Disorders: A Model Intervention.

There is a need to develop novel complementary interventions aimed at enhancing treatment engagement and/or response for veterans with psychiatric and substance use disorders. There is evidence that both mindfulness training and nature exposure (MT/NE) may be beneficial for this population and that combining the two approaches into one intervention might result in synergistic benefit. However, to date, the MT/NE concept has not been tested. This article reports a pilot feasibility and acceptability study of MT/NE which was, in this case, provided via recreational sailing. The primary aim of this project was to develop a model intervention and evaluation process that could be used for future studies of MT/NE interventions using a variety of methods of nature exposure (e.g., hiking, skiing, mountain biking). Results indicate preliminary evidence that it is feasible to utilize MT/NE interventions for the population studied and that the MT/NE model described can serve as a template for future investigations. Further, there were significant pre- to post-intervention decreases in state anxiety, as well as increases in trait mindfulness. Three psychological instruments were identified that might be used in future studies to evaluate MT/NE outcomes. Results from this project provide a model MT/NE intervention template along with evaluation metrics for use in future studies.
