Test Development 1979 Original BOTMP created BOTMP was separated into gross and fine motor. BOT-2 was created to analyze more specific components of fine motor and gross motor. Evaluation of both items were compared and certain testing items eliminated. BOT-2 expanded coverage of fine and gross motor skills. Improved measurement among 4 and 5 year olds. Extended norms through age 21. Improved item presentation. Improved quality of kit equipment.

Test Standardization Uniform procedures for administration & scoring Rules, number of trails, and time limits Scores are compared to age-based norms n= 1, 520 examinees Ages 4 years of age to 21 years and 11 months of age Based on the Current Population Survey (Bureau of the Census, 2001) Standardized Populations: African American, Hispanic, White, & Other Item Bias Review Gender Ethnicity Socio-economic

Psychometric Properties Internal Consistency Reliability Test-Retest Reliability Interrater Reliability for Subtests, Composites, and Short Form by Age Total Composite Ages 4 -7 (. 95) Ages 8 -11 (. 95) Ages 12 -21 (. 96) Total Composite Correlation Ages 4 -7 (. 84) Ages 8 -12 (. 85) Ages 13 -21 (. 79) Total Composite Correlation Ages 4 -21 (. 98) Short Form Ages 4 -7 (. 82) Ages 8 -11 (. 84) Ages 12 -21 (. 87) Short Form Correlation Ages 4 -7 (. 86) Ages 8 -12 (. 87) Ages 13 -21 (. 80) Short Form Correlation Ages 4 -21 (. 98) Fine Manual Control Ages 4 -7 (. 88) Ages 8 -11 (. 85) Ages 12 -21 (. 90) Fine Manual Control Correlation Ages 4 -7 (. 81) Ages 8 -12 (. 54) Ages 13 -21 (. 48) Fine Manual Control Correlation Ages 4 -21 (. 91) Manual Coordination Ages 4 -7 (. 89) Ages 8 -11 (. 86) Ages 12 -21 (. 86) Manual Coordination Correlation Ages 4 -7 (. 62) Ages 8 -12 (. 70) Ages 13 -21 (. 64) Manual Coordination Correlation Ages 4 -21 (. 98) Ages 4 -7 (n=43); (7 -35 days) Ages 8 -11 (n=44); (7 -42 days) Ages 12 -21 (n=47); (10 -42 days)

Psychometric Properties cont’d Test Content- When updating the BOT-2, only functional items that were proven to test its subtest title with moderately high factor were kept. Correlation of BOT-2 Scores with PDMS-2 (Fine Motor Quotient) Scores Ages 4 -5 Correlations of BOT-2 Scores with TVMS-R (Visual Motor Skills) Scores Ages 4 -13 Criterion- Concurrent with 1 -2 studies; demonstrates adequate agreement with a criterion or gold standard measure Total Motor Composite Correlation (. 77) Total Motor Composite Correlation (. 62) Fine Motor Precision (. 61) Fine Motor Integration (. 42) Fine Manual Control (. 55) Manual Dexterity (. 53) Fine Motor Precision (. 55) Fine Motor Integration (. 72) Fine Manual Control (. 70) Construct (Internal Structure)- The BOT-2 uses a composite structure that distinguishes fine motor skills on the basis of the limbs and musculature involved in object manipulation related to functional activities.

Test Length/Cost Fine Motor Composite Form: 20 -30 minutes to administer 10 minutes needed to prepare the testing area Fine Motor Short Form 5 -10 minutes to administer 5 minutes needed to prepare the testing area Cost of Fine Motor BOT-2 Kit $515. 00 Kit includes Manual, Supplemental Manual, Administration Easel, Record Forms (25), Target, Shuttle Block, Balance Beam, Knee Pad. Cost of Complete BOT-2 Kit $837

Scoring Recording Item Raw Score Convert Raw Score to Point Score Make Notes and Observation During Administration Computing Subtest Total Point Scores

Interpretation and Results Gives a good baseline for strengths and weaknesses. Can choose between subtests and use ones that apply the most. When explaining to parents, first identify average to above average scores, then address the below average areas that can be improved with OT.

Areas of Occupation Education participation The fine manual control subtest of the BOT-2 is particularly useful in screening for academic readiness in young children.

Assessment Approach/Environment Assessment Approach: Bottom up Looks at components that are necessary for functional occupational performance during short activities (not specific occupations) Environment: Educational Setting Rehabilitation center/Health Care Setting Home

Frame of Reference / Measurement Concerns Frame of References: Motor Control and Motor Learning Biomechanical and Rehabilitative Measurement Concerns: Examinee inattention with test length Poor test environment Inability to establish rapport Examiner incompetency Substitute for the standardized tools Difficult to use with children who have disabilities Test cost
