Guidelines for Developmental Screening and Assessment Measures

1. Considerations in Selecting Developmental Screening and Assessment Measures Laurie Ford Dept. of Educational & Counselling Psychology & Special Education- UBC Mary Stewart Infant Development Program Early Childhood Education- UBC Early Childhood Assessment Conference Vancouver, BC - May 21, 2009

2. Objectives for the Session • Review a framework for selecting a screening and /or assessment tools • Discuss the important considerations when selecting a screening or assessment tool • Discuss common assessment terms • Discuss types of assessments • Critical evaluation of screening and assessment tools commonly used in ECE.

3. Getting to Know You In partners: • Introduce yourself • Where you are from and what work you do. • What is one question you want answered from this workshop. After 5 minutes: • Introduce your partner to the group and list your question.

4. Evaluation Who uses developmental screening tools on a regular basis? What screening or assessment tools are used?

5. Guidelines for screening and assessment(Miesels and Provence, 1989) 1. Screening and assessment should be viewed as services- as part of the intervention process and not only as a means of identification and measurement.

6. Screening Diagnostic assessment

7. Guidelines for screening and assessment(Miesels and Provence, 1989) 2. Processes, procedures and instruments intended for screening and assessment should only be used for their specific purpose.

8. What is assessment? • Why do we do assessments with children in our programs?

9. Assessment Methods • Observation • Children • Children and Adults • Informal and structured interviews • with children • with parents and child care providers • Rating scales or questionnaires • Direct Assessment

11. Screening Assessment Diagnostic Assessment

12. Screening Screening is a brief evaluation to identify which children need further more in-depth assessment

13. Screening Sensitivity:Ability of the test to correctly identify children with developmental delay Specificity:Ability of the test to correctly identify children without developmental delays

14. Assessment Assessmnt Assessment is the process of obtaining information for the purposes of making evaluative decisions. To identify child and family strengths and need and to propose strategies for intervention.

15. Assessment Norm- referenced • Focus on comparing a child’s performance to other children (their relative development) Criterion-referenced • Identify what skills a child has and had not yet developed (compared to themselves)

16. Diagnostic Assessment Diagnostic approaches tend to identify whether a children have significant symptoms of certain conditions

17. Standardized The standard materials used in each situation. The standard method of presentation of materials in each situation

18. Guidelines for screening and assessment(Miesels and Provence, 1989) 3. Multiple sources of information should be included in screening and assessment

19. Multiple sources

20. Child in Different Environments

21. Guidelines for screening and assessment(Miesels and Provence, 1989) 4. Developmental screening should take place on a recurrent or periodic basis. It is inappropriate to screen young children only once during their early years. Similarly, provisions should be made for reevaluation or reassessment after services have been made.

23. Guidelines for screening and assessment(Miesels and Provence, 1989) 5. Developmental screening should be viewed as only one path to more in-depth assessment. Failure to qualify for services based on a single source of screening information should not become a barrier to further evaluation for intervention services if other risk factors (e.g. environment, medical, familial) are present.

24. Guidelines for screening and assessment(Miesels and Provence, 1989) 6. Screening and assessment procedures should be reliable and valid.

25. Assessment • Reliability:how reliably an instrument or rater measures a variable • Validity:the degree to which a test measures what it is intends to measure

26. Assessment What population was this test “normed” on?

27. Guidelines for screening and assessment(Miesels and Provence, 1989) 7. Family members should be an integral part of the screening and assessment process. Information provided by family members is critically important for determining whether or not to initiate more in-depth assessment and for designing appropriate intervention strategies. Parents should be accorded complete informed consent at all stages of the screening and assessment process.

29. Guidelines for screening and assessment(Miesels and Provence, 1989) 8. During screening or assessment of developmental strengths and problems, the more relevant and familiar the tasks and setting are to the child and the child’s family, the more likely it is that the results will be valid.

30. Which “shoe” will child know?

31. Guidelines for screening and assessment(Miesels and Provence, 1989) 9. All tests, procedures and processes for screening or assessment must be culturally sensitive.

33. Guidelines for screening and assessment(Miesels and Provence, 1989) 10. Extensive and comprehensive training is needed by those who screen and assess very young children.

38. Ages & Stages Questionnaire (ASQ) Training Administration & Scoring Requirements: Questionairres are written at a 6th grade reading level Each questionairre takes about 15 minutes to complete Interpretation must be done by professionals or para professionals Training materials provided in Users Guide and extra video is also available No adaptation for individuals with disabilities

39. Ages & Stages Questionnaire- Social Emotional (ASQ-SE) Can be administered by parents, child care providers, and preschool teachers. If parents, staff should train parents Designed to compliment the ASQ by providing information on social-emotional functioning for children 3 months to 66 months

Early Screening Inventory- Revised (ESI-R) • Brief developmental screening instrument that is individually administered to children ages 3 to 6 years. • Designed to identify children who may be in need of special services to perform successfully upon school entry • ESI-P: Preschool Version 3 yrs-4 yrs 6 mos • ESI-K: Kindergarten Version 4 yrs 5mos -5 yrs 6 mos.
