Accurate measurement of stalking has proven difficult, partly because stalking is characterised by the cumulative effects of a pattern of behaviour. This study aimed to develop and evaluate a new measure of stalking that overcomes the observed shortcomings of existing tools. The Stalking Assessment Indices (SAI) were created using index development principles and evaluated in 244 Australian undergraduate students (M_age= 33.7, 77% female). Seventy-three reported stalking victimisation (experiencing at least five intrusions over at least two weeks causing substantial fear or distress), and 51 reported stalking perpetration. Stalking behaviours reported by victims formed a two-component structure, which was also observed in multidimensional scaling analysis. The perpetration index showed good convergent validity with measures of rumination and aggression, and both indices had adequate test–retest reliability over four weeks. These results suggest that the SAI could provide a consistent and inclusive measure of stalking for use across different research settings.

事实证明，准确测量缠扰行为很困难，部分原因是缠扰行为的特点是行为模式的累积效应。本研究旨在开发和评估一种新的跟踪测量方法，以克服现有工具已观察到的缺点。跟踪评估指数 (SAI) 是使用指数开发原则创建的，并在 244 名澳大利亚本科生₍ Mage= 33.7, 77% 女性）。73 人报告了缠扰行为（至少在两周内经历了至少 5 次入侵，导致严重的恐惧或痛苦），51 人报告了缠扰行为。受害者报告的跟踪行为形成了一个二元结构，在多维尺度分析中也观察到了这种结构。犯罪指数与反刍和攻击性测量显示出良好的收敛效度，并且这两个指数在 4 周内都具有足够的重测信度。这些结果表明，SAI 可以提供一致且包容的跟踪测量方法，以供在不同的研究环境中使用。
