Bruininks–Oseretsky Test of Motor Proficiency-Second Edition (BOT-2) (Bruininks & Bruininks, 2005)
The BOT-2 assesses proficiency in four motor-area composites for individuals aged 4 through 21. Fine manual
control composite measures the motor skills involved in tasks requiring precise control of finger and hand movements.
Manual coordination composite evaluates speed, dexterity, and coordination of upper extremities. Body coordination
composite taps the balance and motor skills required for successful participation in sports, while strength and
agility composite assesses large muscle strength, running speed, and postural control during walking and running. The
four composite scores are combined to yield a total motor composite score. For the composites, internal consistency
reliability coefficients ranged from 0.78 to 0.97, test–retest coefficients over an interval of 7–42 days ranged from 0.52 to
0.95, and inter-rater reliability coefficients exceeded 0.92 (Bruininks & Bruininks, 2005). The BOT-2 had good reliabilities
(internal consistency, test–retest reliability, responsiveness) and construct validity in children with ID (Wuang, Lin, & Su,
2009; Wuang & Su, 2009). The strength and agility composite (SAC) used in the present study included five subtests:
standing long jump, push-ups, sit-ups, wall sit, and V-up. The average age-adjusted standard scores for composites are
100 (SD = 15).
