Slide 1

Standards to Help Guide Next Generation Interventions: Some Examples from Randomized Controlled Trials Concerning School Readiness Craig T. Ramey and Sharon L. Ramey Presentation at gathering on “Intervening Early: Progress and Opportunities in Child Service Settings” Sponsored by NIDA, ACF, NICHD, NIMH, OBSSR & SAMHSA Washington, DC September 18-29, 2007

Slide 2

Scientific Foundation for Early Intervention Research on neuroplasticity (creature models) Studies of amazing hardship (halfway houses, maternal hardship, separation) Demonstration ventures Naturalistic and longitudinal studies Randomized controlled trials (RCTs) to test the viability of an arranged mediation to modify the life course

Slide 3

PRINCIPLES OF EFFECTIVE EARLY INTERVENTION Timing (onset, length of time, counterbalance) Intensity (every day/wk/mth/yr(s)) Direct learning encounters Breadth of administrations/backings Individual contrasts Environmental upkeep Ramey & Ramey (1998), American Psychologist

Slide 4

Randomized Controlled Trials (RCTs) we have led include: Basic Studies of Early Learning The Abecedarian Project (ABC) Project CARE Infant Health and Development Program (8 locales) Romanian Orphanage Studies Intensive Pediatric CI Therapy (cerebral paralysis) National Head Start-Public School Transition Demonstration Study (31 destinations) Pre-K Curriculum Comparison Study Child Care Coaching Studies Ramey & Ramey

Slide 5

Applied Biosocial Contextual Development (ABCD): A Framework for Understanding Human Development

Slide 6

Examples outlining these standards from some of our longitudinal RCTs Interventions for kids from profoundly bankrupted, regularly clamorous situations (Abecedarian Project and Project CARE; Romanian Orphanage studies) Targeted intercessions for Low birthweight, untimely newborn children (IHDP) Children with moderate to extreme neuromotor disabilities (Project ACQUIRE)

Slide 7

Principle of Timing When the mediation starts and closures can fundamentally impact the effect on improvement Magnitude of this impact depends, to some extent, on the result measured, its formative course, and the intercession\'s way Principle is exceptionally like that in teratology

Slide 8

Two-Phase Design of Abecedarian Project Campbell & Ramey, American Educational Research Journal , 1995

Slide 9

Treatment Group _ Adequate sustenance Supportive social administrations Free essential medicinal services Preschool treatment: Intensive (entire day, 5 days/week, 50 weeks/year, 5 years) “Learningames” Curriculum Cognitive/Fine Motor Social/Self Motor Language Individualized pace Abecedarian Preschool Program Control Group _ Adequate nourishment Supportive social administrations Low-cost or free essential health care Campbell & Ramey, 1995 American Educational Research Journal

Slide 10

Brief Summary of Abecedarian K-2 Transition Program Individualized spotlight on scholarly and learning exercises in school and at home Emphasis on perusing, arithmetic, and composing Master Home/School Resource Teachers (12 kids and families for each educator) Development of an individualized and recorded supplemental educational programs for every youngster Explicit consideration and activity applicable to family circumstances, as required Summer camps with scholastically pertinent encounters Ramey & Ramey, 1999

Slide 11

The Abecedarian (ABC) Project Longitudinal Effect Sizes for Reading by Treatment Group Campbell, Ramey, Pugello, Sparling, & Miller-Johnson (2001) Applied Developmental Science

Slide 12

Key Findings from Abecedarian Project (“Abecedarian” …one who takes in the nuts and bolts, for example, the letters in order) year and a half to 21 Years Old Intelligence (IQ) Reading and math aptitudes Academic locus-of-control Social Competence Years in school, including school Full-time job Grade Repetition Special Education position Teen Pregnancies Smoking and medication use Plus advantages to moms of these kids (instruction, livelihood) Ramey et al, 2000

Slide 13

Principle of Dosage Interventions which are more concentrated (as filed by hours every day, days every week, and so on.) produce bigger changes Exact determination of “optimal doses” has been exceptionally troublesome, generally because of expense and commonsense issues Some proof reliable with “threshold hypothesis” (basically at lower point of confinement) Highly like measurements reaction bend guideline in teratology Support comes for the most part from cross-study examinations

Slide 14

Principle of Direct Learning Experiences Interventions that straightforwardly adjust the child’s encounters (i.e., exchanges with others and environment) have altogether more prominent impacts than do those that in a roundabout way change the child’s life (e.g., child rearing projects, coordination of administration conveyance backings) Note: lion\'s share of right on time intercessions have concentrated on circuitous impacts in light of thought that these would prompt practical ecological backings (to date, this theory has not been affirmed )

Slide 15

Project CARE * RCT intended to reproduce Abecedarian Project (ABC) * Added another treatment gathering to test the adequacy of an escalated 5-year home going to program utilizing the ABC intercession (to test aberrant versus direct impacts) * Affirmed same discoveries in ahead of schedule youth through to youthful adulthood from instructive mediation, however no advantages of home going by on kid results

Slide 16

Adapted from Wasik, Ramey, Bryant, & Sparling. Kid Development , 1990

Slide 17

Principle of Breadth of Services/Supports Early mediations that are multi-segment and location youngster needs in wellbeing, insight, social-enthusiastic advancement by and large deliver bigger and more enduring impacts Limitations : Research proof has numerous jumbles, following more extensive projects likewise have a tendency to be more escalated and incorporate direct learning encounters most intercession projects tried in RCTs concentrated on kids with various needs and danger conditions (because of normal co-event)

Slide 18

Principle of Individual Differences Some kids advantage more (or less) than do other kids This rule has been certified essentially by: Findings that kids with more prominent requirements for ecological backings advantage more Findings that kids with more generous CNS affront may not advantage as much from non specific (i.e., not range particular intercession) intercession Similar to teratology guideline of differential hereditary powerlessness or Gene X Environment Interaction Effect

Slide 19

The Infant Health and Development Program (IHDP) Intervention repeated Abecedarian Project New target bunch = untimely, low birthweight kids incubation and < 2500 gm during childbirth Conducted at 8 locales (N=985 kids & families) Intervention changed for particular natural danger components Educational mediation kept going just until 3 yrs old (CA) Follow-up reported through age 18 yrs IHDP, JAMA , 1990

Slide 20

Examples of discoveries certifying Principle of Individual Differences In ABC, kids with most minimal IQ moms (<70) indicated notably bigger advantages than those whose moms had IQs >90 In IHDP, intercession more useful in counteracting mental hindrance (IQ<70) for untimely, low birthweight kids with less instructed moms or lower IQ moms In IHDP, low birthweight babies did not advantage as much

Slide 21

Stanford-Binet IQ Scores at 36 Months Heavier LBW Group (2001-2500gm) Infant Health and Development, JAMA , 1990 Ramey, AAAS, 1996

Slide 22

Stanford-Binet IQ Scores at 36 Months Lighter LBW Group (<2000gm) Infant Health and Development, JAMA , 1990 Ramey, AAAS, 1996

Slide 23

Infant Health and Development Program Children’s IQ at 36 months: Maternal Education X Treatment Group Ramey & Ramey (1998), Preventive Medicine (n=232) (n=162) (n=166) (n=104) (n=134) (n=63) (n=76) (n=48)

Slide 24

Principle of Environmental Maintenance Benefits of ahead of schedule intercession are maintained longer when kids keep on accepting solid, proper natural backings after intercession closes Limitation: Almost difficult to partitioned impacts of ensuing denying or destructive situations (which could turn around advantages of right on time intercession) from the requirement for genuine “maintenance”

Slide 25

Some Implications of Principles for Service Settings Develop adaptable option mixes of administrations for advantage/expense concentrates instead of assess single administration correlations Expect and plan to find subgroups of members who display differential levels of danger and who may demonstrate differential levels of reaction to treatment Develop an express model for populace and subpopulation attributes; proposed essential pathways through which administrations are planned to have an effect on particular results which are themselves checked in a continuous manner

Slide 26

Some Implications of Principles for Service Settings Develop satisfactory information frameworks to record recurrence and nature of administration accessibility and administration usage at the individual level Conduct examinations and report them openly at any rate on a yearly premise Do not expect that suitable control bunch members are, or ought to be, an untreated gathering When conceivable, set up unequivocal associations with imp
