Technology-based strategies for the prevention and management of suicidal behavior are widely referenced for identifying vulnerable groups and for supporting clinical reasoning, decision-making, and appropriate referrals. In this study, we estimated the interface and content validity evidence of an interactive mobile application developed for managing suicidal behavior. This methodological study employed psychometric parameters to evaluate the content and interface of the mobile application, following five action phases: analysis, design, development, implementation, and evaluation. A total of 27 healthcare professionals participated, selected by convenience sampling, all working within the Psychosocial Care Network across different regions of Brazil. Data were collected using an electronic form, the Delphi technique for evaluation rounds, and a Likert scale to achieve consensus. The validity analysis was based on a Content Validity Index (CVI) equal to or greater than 0.80. The results showed that GerenciaVida, a technology developed for healthcare workers-regardless of their level of care or professional category-can be used to screen for suicide risk in the general population and indicate preventive alternatives. The app demonstrated satisfactory indicators of content validity (0.974) and interface validity (0.963), reflecting clarity (0.925), objectivity (1.00), adequacy (0.925), coherence (0.962), accuracy (0.962), and clinical relevance (1.00). The development path of this mobile application provided scientific, technological, and operational support, establishing it as an innovative care tool. It consolidates valid evidence that supports the identification, risk classification, and prevention of suicidal behavior in various healthcare contexts.
基于技术的自杀行为预防和管理策略在识别弱势群体以及支持临床推理、决策和适当转诊方面被广泛引用。在本研究中，我们评估了一款为管理自杀行为而开发的交互式移动应用程序的界面和内容效度证据。这项方法学研究采用心理测量参数来评估该移动应用程序的内容和界面，遵循分析、设计、开发、实施和评估五个行动阶段。共有27名医疗保健专业人员通过便利抽样选出，他们都在巴西不同地区的心理社会护理网络内工作。数据通过电子表格收集，采用德尔菲技术进行评估轮次，并使用李克特量表以达成共识。效度分析基于内容效度指数（CVI）等于或大于0.80。结果表明，GerenciaVida这款为医护人员开发的技术——无论其护理水平或专业类别如何——可用于筛查普通人群的自杀风险并指出预防方案。该应用程序展示了令人满意的内容效度指标（0.974）和界面效度指标（0.963），反映出清晰度（0.925）、客观性（1.00）、充分性（0.925）、连贯性（0.962）、准确性（0.962）和临床相关性（1.00）。这款移动应用程序的开发路径提供了科学、技术和运营支持，将其确立为一种创新的护理工具。它巩固了支持在各种医疗保健环境中识别、风险分类和预防自杀行为的有效证据。
