There is a growing impetus towards usage of test batteries in talent identification (TID) programmes in rugby. Consequently, there are many test batteries in existence profiling anthropometric, physiological characteristics and rugby-specific skills. There is no consensus in the literature on the constituent variables and corresponding tests required to inform TID programs. Following development of a new test battery called the SCRuM (School Clinical Rugby Measure), this study aimed at establishing face, logical validity and practical feasibility of included tests. The test battery, initially comprised of 23 items, had its face and logical validity evaluated by five (5) adolescent rugby coaches and 20 rugby experts, respectively. Logical validation was conducted in two questionnaire-based rounds with Content Validity Index (I-CVI) calculated for each variable. Subsequently, a cross-sectional study targeting 30 local rugby coaches was conducted to determine the perceived practical feasibility of each test item. The results showed excellent I-CVI (>0.78) for 17 variables (speed, weight, height and skin fold measures, repeated high-intensity exercise performance ability, prolonged high-intensity intermittent running ability, change of direction speed, anaerobic capacity, lower-and upper body muscular power and strength, muscular flexibility, reactive agility, passing for accuracy, tackling proficiency, and catching). However, three tests, namely, Reactive Agility, One Repetition Maximum Back Squat and One Repetition Maximum Bench Press had low test-feasibility indices (T-FI< 35) suggesting practicality concerns with implementation in the Zimbabwean context. Thus, these findings suggest the need for substitution or development of new practically feasible tests for upper-and lower body muscular strength and reactive agility.
在橄榄球的人才识别（TID）计划中，越来越倾向于使用测试组合。因此，存在许多测试组合来分析人体测量学、生理学特征和橄榄球特定技能。在文献中，对于构成 TID 计划的变量和相应的测试，还没有达成共识。在开发了一种名为 SCRuM（学校临床橄榄球测量）的新测试组合后，本研究旨在确定所包含测试的表面效度、逻辑有效性和实际可行性。该测试组合最初由 23 个项目组成，分别由 5 名青少年橄榄球教练和 20 名橄榄球专家对其进行了表面和逻辑有效性评估。逻辑验证分两轮进行，采用内容有效性指数（I-CVI）对每个变量进行计算。随后，针对 30 名当地橄榄球教练进行了一项横断面研究，以确定每个测试项目的实际可行性感知。结果显示，17 个变量的 I-CVI（>0.78）非常高（速度、体重、身高和皮褶测量、重复高强度运动能力、长时间高强度间歇跑步能力、变向速度、无氧能力、上下肢肌肉力量和力量、肌肉柔韧性、反应敏捷性、传球准确性、擒抱熟练度和接球）。然而，三个测试，即反应敏捷性、一次重复最大深蹲和一次重复最大卧推，具有较低的测试可行性指数（T-FI<35），这表明在津巴布韦的背景下，实施这些测试存在实际可行性问题。因此，这些发现表明需要替代或开发新的具有实际可行性的上下肢肌肉力量和反应敏捷性测试。
