ENHANCE Update Research Underway on the Validity of the Child Outcomes Summary (COS) Process ECO Center Advisory Board Meeting March 8, 2012 Arlington, VA ENHANCE is funded by grant R324A from the the U.S. Dept. of Education, Institute for Educational Sciences
Topics Project design - review Data collection progress What we are learning –Implementation –Child assessment study –State data study Next steps
Project Design
1.Conduct a program of research to examine the validity of ratings generated by COS and identify conditions that lessen validity. 2.Revise the COS and supporting materials based on study findings. 3.Identify a series of validity analyses that can feasibly be conducted in states to allow each state to examine the validity of its own COS data on an ongoing basis. ENHANCE Project Objectives
Validity – What Are We Trying to Demonstrate? Validity is NOT a characteristic of an assessment or measurement device. Validity is a characteristic of the data produced by the tool and how these data are used. Are data valid for the purpose of….. Implications: –State A’s COS data could be valid; –State B’s COS data could not be. Standards for Educational and Psychological Testing(1999) by American Educational Research Association, American Psychological Association, National Council on Measurement in Education
Validation Process Validation process: –Develop propositions (validity argument) - If data were valid for this use, then we would see…. –Collect evidence to examine each of those propositions
Examples of propositions in the COS Validity Argument 3. Children differ from one another with regard to level of functioning in the 3 outcome areas as reflected in COS ratings. 7. Functioning (COS ratings) in an outcome area at time 1 is related to functioning in that area at a later point in time. 9. COS ratings will be related to the nature and severity of the child’s disability.

Studies and Data Collection Progress
ENHANCE Studies Provider Survey Team Decision-Making Comparison with Child Assessments State Data Study
Provider Survey Goals Learn about COS implementation – processes in use Identify providers’ knowledge and training experiences Describe perceptions about if COS produces an accurate rating and influences on that Understand impact of COS on practice Process & Sample Online survey responses All providers in program who participate in COS Status Survey underway, continues through April
Team Decision-Making Study Goals Examine understanding and application of outcomes and rating criteria Describe team process Identify if ratings are consistent with evidence discussed Process & Sample Video teams discussing COS ratings 210 children’s teams Status Data collection underway Code videos this summer & fall
What Are We Learning?
Considerable variability across states and even across programs, within a state Training Ongoing staff support and quality assurance Teaming (not just for COS) Parent involvement Timing and Process Implication: Results will tell us about COS validity under real-world conditions Implementation
Number of Providers in COS Ratings - Preliminary Percentage of COS forms Number of providers
Goals Compare entry and exit COS ratings to BDI-2 and Vineland-II scores Compare conclusions from COS and assessments Process & Sample Longitudinal, external assessor at program entry & program exit 216 children Study Status Local, trained assessors in place Recruiting families since Aug Sample shows expected variability, including initial COS ratings, tool scores Comparison with Child Assessments Study
Comparison with Child Assessments Study – Preliminary…
3. There is variability in children’s functioning in the three outcome areas and that variability is reflected in the COS ratings. Validity argument claims
Distributions of Preliminary COS Ratings (1-7) EI (n=71) ECSE (n=49) Ratings
3. There is variability in children’s functioning in the three outcome areas and that variability is reflected in the COS ratings. 10. COS ratings in the corresponding outcome areas are moderately correlated with: o the social-emotional (Outcome 1), o cognitive (Outcome 2), o communication (Outcome 2), and o adaptive (Outcome 3) domain scores of assessment tools. Validity argument claims
Methods table Methods
Preliminary correlations between COS Ratings and assessment tools What expect to see? Methods
Preliminary Correlations: COS Ratings & Assessment Scores ECSE larger COS-Assessment Correlations than EI
Correlations: BDI-2 and Vineland-II Domains ECSE larger BDI-Vineland Correlations than EI
Methods COS Group 1 – Ratings of 1, 2, 3 COS Group 2 – Ratings of 4, 5 COS Group 3 – Ratings of 6, 7
Outcome 1: Positive Social Relationships EI (n=71) ECSE (n=49)
EI (n=71) ECSE (n=49) Outcome 2: Acquiring and Using Knowledge and Skills
EI (n=71) ECSE (n=49) Outcome 3: Taking Appropriate Action to Meet Needs
Summary of preliminary findings Patterns Means for groups generally follow expected directions on assessment tools Group comparisons showed expected differences Effect sizes were nearly all larger for ECSE than EI For COS – assessment tool comparisons For comparisons between assessment tools by the same external assessor More data are needed for final conclusions
State Data Study Goals Examine characteristics of COS data and relationships to other variables Look for consistency in patterns across states to test claims Sample All valid COS data within the state for a reporting year states conducting all analyses Additional states sharing select analyses Status Piloted procedures with 3 Part C, 3 Part B Preschool states Now working with 4 Part C, 6 Part B Preschool states Recruiting more states, requesting data
7. Functioning, as reflected in the COS rating, in an outcome area at time 1 is related to functioning in that area at a later point in time. Validity argument claims

3. There is variability in children’s functioning in the three outcome areas and that variability is reflected in the COS ratings. 14. COS rating distributions at entry will be related to the disability-related characteristics of the population served by states. Validity argument claims
