Suicide is a major health concern around the globe, including India. Identifying various risk factors and confirming individual cases of is challenging to investigating agencies and clinicians. This study was carried out with the intention of preparing a standardized minimum data set (MDS) for the National Suicide Registry of India (NSRI) as recommended by the National Suicide Prevention Strategy (NSPS) for framing policy decisions on suicide.
This study was conducted in three steps: a literature review to identify data elements, appointing experts and finalization of MDS items and content validation by two rounds of Delphi. The data elements were validated by calculating content validity index (I-CVI) and content validity ratio (CVR).
After literature review, the extracted data elements were divided into eight headings and forwarded to multidisciplinary experts. A total of 28 experts participated in this study. A total of 176 data elements were evaluated, out of which 169 data elements were finalized based upon I-CVI and CVR calculation and used for standardizing this MDS.
A standardized MDS has been developed for NSRI. This MDS will facilitate uniform data collection on suicides across the country, addressing existing limitations in data collection. By analyzing data gathered through the MDS, policymakers can inform the NSPS, ultimately helping to reduce suicide rates in India.
自杀是包括印度在内的全球主要健康问题。识别各种风险因素并确认个别自杀案例对调查机构和临床医生来说具有挑战性。本研究旨在按照国家自杀预防战略（NSPS）的建议，为印度国家自杀登记处（NSRI）编制一份标准化的最小数据集（MDS），以便制定有关自杀的政策决策。
本研究分三个步骤进行：通过文献综述确定数据元素，任命专家并最终确定MDS项目，以及通过两轮德尔菲法进行内容验证。通过计算内容效度指数（I-CVI）和内容效度比（CVR）对数据元素进行验证。
文献综述后，提取的数据元素分为八个标题并提交给多学科专家。共有28位专家参与了本研究。共评估了176个数据元素，其中169个数据元素根据I-CVI和CVR计算结果最终确定，并用于该MDS的标准化。
已为NSRI开发了标准化的MDS。该MDS将有助于在全国范围内统一收集自杀数据，解决数据收集方面的现有局限性。通过分析通过MDS收集的数据，政策制定者可为NSPS提供信息，最终有助于降低印度的自杀率。
