1 DETERMINING ELIGIBILITY IN MA EARLY INTERVENTION A General Overview to Scoring

2 TODAY’S AGENDA  Background information about the BDI-2  Completing the Record Form  Determining Eligibility

3 BACKGROUND INFORMATION  Developed for children birth-7.11 years old  Standardized test with nationally representative sample of 2500 children  Bias reviews on all items conducted for the following areas of concern:  Gender  Ethnicity  Cultural  Regional  Socio-economic

4 OVERVIEW OF ASSESSMENT NORM- REFERENCED TESTING  Allow for comparisons of a child’s performance with that of a reference group --> children of the same age  Generates normative scores: Standard scores/Developmental Quotients  Mean = 100, Standard Deviation = 15 Scaled scores  Mean = 10, Standard Deviation = 3  Norm-referenced tests follow standardized administration procedures, meaning that administration is conducted in a uniform and consistent way so that a child’s performance can be compared fairly to the performances of other children.

5 DETERMINING ELIGIBILITY: DEVELOPMENTAL QUOTIENT = STANDARD DEVIATIONS BELOW THE MEAN INTERPRETATION OF EVALUATION RESULTS * Red line indicates 1.5 SD

6 Scoring and Interpreting Determining Eligibility

7 ADMINISTRATION  STARTING POINT: first item administered in each sub-domain. Chosen by the evaluation team. Often based on the child’s chronological age  BASAL: Functional level at which child shows mastery of tasks  Child must score 3 consecutive 2-point responses  CEILING: Level at which tasks become too difficult  Child must score 3 consecutive 0-point responses

8 Step 2 Test in reverse order until basal is met Step 1 Start Point GM 20 Step 3 Continue testing forward until ceiling is met What is the raw score for the Gross Motor Subdomain?

9 Calculating the Raw Score  For each subdomain add up the 2 scores and the 1 scores to determine the raw score.  REMEMBER: the basal assumes that the child would get a score of 2 for all of the preceding tasks, so you must add in these sums to the raw score.  Transfer the raw score onto the Scoring Profile on the front of the scoring booklet (2 nd column of large table)  Use the raw scores to determine the percentile rank and scaled scores for each subdomain using Appendix B.

10 Scoring continued…  Use exact chronological age and obtained raw scores to derive (Appendix B):  Age Equivalents (subdomains)  Scaled Scores (subdomains)  Percentile Ranks (subdomains & domains)  Determine the Sum of Scaled Scores for each domain and then use these numbers to derive (Appendix C):  Developmental Quotients (domains)  Confidence Intervals (domains)  Create subdomain & domain profiles

11 Scoring Exercise SCORE SUMMARY 1. Enter subdomain raw scores. 2. Use Appendix A to obtain age equivalent (AE). 3. Use Appendix B to obtain percentile rank (PR) and scaled score. 4. Total subdomain scaled scores within each domain. Then total the totals.

12 Scoring Exercise Con’t SCORE SUMMARY CA: 5 years, 1 month 1. Enter raw scores for subdomains. 2. Record AE (Ap. A). 3. Record PR and SS (Ap. B). 4. Total subdomain scaled scores & Total.

13 Scoring Exercise Con’t DOMAIN & BDI-2 TOTAL SCORES 1. Transfer domain scaled score totals to sum of scaled scores boxes. 2. Use Appendix C to obtain the DQ, PR, and Confidence Interval (90% or 95%) for all 5 domains and the BDI-2 Total.

14 Scoring Exercise Con’t COMPOSITE PROFILE 1. Transfer the developmental quotients to the appropriate boxes. 2. Place a dot (or an X) in the column for the obtained DQ. 3. Connect the dots (or X’s) to obtain a norm-referenced profile of the child’s performance on the composites. 4. Do not connect the domains to the total score. 5. If a domain was not administered do not connect lines through that domain.
