Data from: Logical validation and evaluation of practical feasibility for the SCRuM (School Clinical Rugby Measure) test battery developed for young adolescent rugby players in a resource-constrained environment

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.
