Abstract

The Broad-Minded Affective Coping (BMAC) intervention is a theory-driven cognitive therapy aiming to reduce suicidal ideation through guided positive mental imagery. We explored the feasibility and acceptability of a randomised controlled trial to evaluate the BMAC intervention in university students. The trial was a two-arm, randomised (ratio 1:1) controlled feasibility trial comparing risk assessment and signposting with or without the BMAC intervention (ISRCTN 13621293; ClinicalTrials.gov NCT05296538). Participants had recent suicidal ideation or behaviour. Feasibility outcomes concerned recruitment, retention, intervention adherence, completion of a suicidal ideation assessment, and the safety of the procedures. Clinical outcomes and putative mechanisms were recorded at baseline and after eight, 16, and 24-weeks. All feasibility criteria were met. Sixty-five participants were randomized (99 % of target sample). Retention to follow-up was high at all timepoints (89–91 %). In the treatment arm, 30 out of 33 participants (91 %) attended ≥2 sessions of the BMAC. Retained participants completed a suicidal ideation assessment with no missing data. There were 19 serious adverse events, but none were related to the trial procedures or intervention. Effect estimates for suicidal ideation favoured the intervention. The trial and intervention were acceptable, feasible, and safe. The efficacy of the intervention requires evaluation in a definitive trial.

针对大学生自杀意念的心理意象干预：一项评估盲、随机对照可行性试验

宽心情感应对（BMAC）干预是一种理论驱动的认知疗法，旨在通过引导积极的心理意象来减少自杀意念。我们探讨了一项随机对照试验的可行性和可接受性，以评估大学生的BMAC干预。该试验是一项两组随机对照可行性试验，比较有或没有BMAC干预的风险评估和路标(ISRCTN 13621293；ClinicalTrials.gov NCT05296538)。参与者近期有自杀意念或行为。可行性结果涉及招募、保留、干预依从性、自杀意念评估的完成和程序的安全性。在基线和8周、16周和24周后记录临床结果和可能的机制。符合所有可行性标准。65名参与者被随机分配（99%的目标样本）。随访率在所有时间点均较高（89 - 91%）。在治疗组，33名参与者中有30名（91%）参加了≥2次BMAC治疗。保留的参与者完成了自杀意念评估，没有遗漏数据。有19个严重不良事件，但没有一个与试验程序或干预有关。对自杀意念的效果估计支持干预。试验和干预是可接受的、可行的和安全的。干预措施的有效性需要在确定的试验中进行评估。

期刊介绍： The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
