OBJECTIVE: To examine the psychometric and clinimetric properties of the
Melbourne Assessment 2 (MA2), an outcome measurement that is increasingly used in
clinical studies. DESIGN: Psychometric and clinimetric study. SETTING: Community.
PARTICIPANTS: Seventeen children with cerebral palsy (CP) from 5 to 12 years were
recruited for the estimation of the test-retest reliability and minimal
detectable change (MDC). Thirty-five children with CP were recruited to receive
an 8-week intensive neurorehabilitation intervention to estimate the validity,
responsiveness, and minimal clinically important difference (MCID).
INTERVENTIONS: Thirty-five children with CP received upper limb
neurorehabilitation programs for 8 weeks. MAIN OUTCOME MEASURES: The MA2 and the
criterion measures, including the Bruininks-Oseretsky Test of Motor Proficiency,
2nd edition (BOT-2), the Box and Blocks Test (BBT), and the Pediatric Motor
Activity Log-Revised (PMAL-R), were evaluated at pretreatment and posttreatment.
RESULTS: The MA2 has 4 subscales: range of motion, fluency, accuracy, and
dexterity. The test-retest reliability of the MA2 is high (intraclass correlation
coefficient, .92-.98). The significant relationships between the MA2 and BBT,
BOT-2, and PMAL-R support its validity. The significance of paired t test results
(P<.001) and large magnitudes of the standardized response mean (1.70-2.00)
confirm the responsiveness of the MA2. The MDC values of the 4 subscales of the
MA2 are 2.85, 1.63, 1.97, and 1.84, respectively, and the suggested MCID values
of these 4 subscales are 2.35, 3.20, 2.09, and 2.22, respectively, indicating the
minimum scores of improvement to be interpreted as both statistically significant
and clinically important. CONCLUSIONS: The study findings indicate that the MA2
has sound psychometric and clinimetric properties and is thus an adequate
measurement for research and clinical applications.
