The present study was aim to evaluate the acceptability and preliminary effectiveness of a mobile-health application, CALMA, based on dialectical behavioral therapy skills. CALMA was proposed as an adjunct to therapy for the reduction of non-suicidal and suicidal self-injury behaviors. A parallel design was used to compare the intervention group (DBT + CALMA) and the comparison group (DBT). Patients were randomized based on their groups following a randomized cluster design. After treatment, patients completed a follow-up assessment four weeks later. Each cluster was represented by a different DBT Skills Training Group offered weekly at FORO Foundation for Mental Health. Six DBT Skills Training groups were randomized to the intervention or comparison group. Twenty-one individuals met inclusion criteria and eighteen were included in the analysis. Acceptability was measured with the User Experience Questionnaire short version (UEQ-s) and preliminary efficacy with the Self-injurious thoughts and behaviors interview (SITBI). CALMA shows good acceptability to be used as an adjunct to therapy specific to the reduction of suicidal and non-suicidal self-directed violence. Evidence for preliminary efficacy included a high probability of decreased in more behaviors evaluated with the SITBI pre- and post-intervention for the group that received CALMA as compared to the comparison group. Our study provides initial evidence for the effectiveness and acceptability of CALMA. Future studies scaling up this intervention in a larger number of participants are necessary. CALMA may be especially useful in low and middle-income Latin American countries to improve access to evidence-based interventions openly available in Spanish and free to download.HighlightsCALMA is a DBT-based app aimed to reduce non-suicidal and suicidal self-directed violence.The app showed good acceptability by usersA high probability of decrease in suicidal ideation, suicidal plan, suicidal gesture, thoughts about NSSI and NSSI pre- and post-intervention was observed.
本研究旨在评估基于辩证行为治疗技能的移动健康应用程序 CALMA 的可接受性和初步疗效。CALMA 被提议作为辅助治疗，以减少非自杀性和自杀性自我伤害行为。采用平行设计比较干预组（DBT+CALMA）和对照组（DBT）。根据随机分组设计，患者被随机分为两组。治疗后，患者在四周后完成随访评估。每个集群由每周在 FORO 基金会心理健康中心提供的不同 DBT 技能培训小组代表。六个 DBT 技能培训小组被随机分配到干预组或对照组。符合纳入标准的 21 人中有 18 人纳入分析。可接受性通过用户体验问卷短版（UEQ-s）进行测量，初步疗效通过自我伤害思想和行为访谈（SITBI）进行测量。CALMA 作为一种特定于减少自杀和非自杀性自我伤害的治疗辅助手段，具有良好的可接受性。初步疗效的证据包括，与对照组相比，接受 CALMA 的组在 SITBI 评估的更多行为中，干预前后的减少概率更高。我们的研究为 CALMA 的有效性和可接受性提供了初步证据。未来需要在更多参与者中扩大这项干预措施的研究。CALMA 可能特别有助于在中低收入的拉丁美洲国家，改善对西班牙语提供的、免费下载的循证干预措施的获取。
CALMA 是一款基于 DBT 的应用程序，旨在减少非自杀性和自杀性自我伤害。
用户对该应用程序的接受度良好。
观察到干预前后自杀意念、自杀计划、自杀姿势、关于 NSSI 的想法和 NSSI 的自杀意念、自杀计划、自杀姿势、关于 NSSI 的想法和 NSSI 的发生率都有显著下降。
