1. Clinical Observations of Motor and Postural Skills- 2nd Edition (COMPS-2) Becca Price & Shelby Berthelot

2. Purpose Performance based screening test
Descriptive measure that helps identify presence of motor problems with a postural component
Helps identify if additional assessments need to be performed
Determine type of intervention approach to use
Children ages 5-15

3. Items 6 items: Slow Movements Rapid Forearm Rotation
Finger-Nose Touching
Prone Extension Posture
Asymmetrical Tonic Neck Reflex
Supine Flexion Posture

4. Testing Procedures Recommended to perform 6 tasks in order
Last 3 tasks must be performed in order
Use standardized methods and exact wording in bold
Therapist performs task first then instructs them to imitate

5. Test Development and Standardization
Initial Test
Went from 19 items to 6
Used by experienced pediatric Ots in 2 cities
123 children age 5 to 9.11 , 67 with DCD and 56 with no know motor problem
Upward age extension
261 children between age 10-16

6. Psychometric Properties
Reliability:
Test-Retest = .92
Interrater
(4 different raters) = .87
Internal Consistency = .75
Age = .77
Age = .69
Validity:
Content- established by expert opinion
Construct- empirical item analysis
Test Sensitivity:
100% for ages 5,8,9
82% for ages 6 & 7
Low percentage for ages >9.11
Criterion
Concurrent- BOTMP subtests, Developmental Coordination Disorder Questionaire
Predictive- Correctly classified ~ 80% of the time

7. Test Length and Cost Takes about 15-20 minutes to administer and score
Manual = $36
Score Sheets = $18 for 20 sheets

8. Scoring

10. Test Results
Less than a 0 indicates problems in motor and postural skills
Greater than a 0 indicates normal functioning in motor and postural skills
A weighted score is given for each of the 6 items and a weighted total score is given

11. Areas of Occupation Addressed
Play
Functional Mobility

12. Assessment Approach Bottom up
Tests the different components of motor control
Measures:
Move slowly and symmetrically
Cerebellar-vestibular integrity
Cerebellar coordination
Vestibular-proprioceptive processing dysfunction
Degree of ATNR present
Somato-dyspraxia

13. Where the Tool is Used Rehabilitation Clinic/ Health Care setting
Education Setting
Private Pediatric Clinic

14. Frame of Reference Motor control Movement disorder Postural stability
Motor coordination

15. Measurement Concerns
The assessment does not take into consideration children who have neurological or neuromotor problems, such as cerebral palsy or epilepsy.
The results do not return normative data in the way of age equivalence.
The assessment is not meant to measure change in motor function over time.
