      Today @clairlemon made me aware of a study that the authors claim that is "proof of concept" that early childhood intervention can reduce later social ills. But is it?

      The study is called the Early Years Education Program (EYEP). It is targeted to children who are at high risk of school failure and other negative social outcomes. It's a lot like the Perry Preschool Project in the 21st century.

      The study is not finished, but this month the authors released the report for the children's outcomes after 24 months in the program. Later reports are scheduled for 36 months in the program and six months after kindergarten entry. Full report here: https://fbe.unimelb.edu.au/__data/assets/pdf_file/0003/3085770/EYERP-Report-4-web.pdf …

      Here is what's good about the study: ✅An intensive program. Typical programs (see below) don't provide permanent academic or social benefits. If we're serious about improving IQ or other outcomes, the intervention needs to be INTENSE.https://twitter.com/Russwarne/status/1091198811957997568?s=20 …

      Low-income children randomly assigned to state pre-K performed better than control children in kindergarten. After that, control children caught up. By grades 1-3, control children surpassed the treatment group in most variables. #psychology #edchat https://doi.org/10.1016/j.ecresq.2018.03.005 … pic.twitter.com/yE9xko7Jcf

      Kids in the EYEP treatment had 3 yrs of child care (5 hrs per day, 50 weeks per year) w/an academic curriculum designed & implemented by highly trained staff. An infant mental health consultant visited the homes regularly & an in-house qualified cook ensured nutritious meals.pic.twitter.com/ZVqXlGBEU9

      Another strength of EYEP: ✅ Random assignment. I cannot stress this enough. Moreover, the researchers checked the randomization on their dependent variables, and the randomization process balanced out the experimental and control groups.

      ✅EYEP is also targeted at the right people. These kids are truly at risk. All had at least 2 risk factors from this list, and 70% had 4 or more. 35% had 6 or more. These are exactly the children society should be concerned about.pic.twitter.com/ttouPGaFpi

      Now for the drawbacks: ❌Sample size is too small. With 145 children total, the statistical power for the expected d = .25 effect size is only 44.9%. ❌And attrition makes that problem worse. 34% of the control group and 22% of the treatment group dropped out.

      ❌Statistical significance criteria are fishy. The one-tailed test decision is reasonable. (No one thinks EYEP will harm children.) But there is no justification for setting alpha at .10. A one-tailed alpha of .10 is equivalent to a two-tailed alpha a .20(!).pic.twitter.com/k5KwuQE5HA

      No reason to promote this dumb study. Just another useless intervention study being promoted by the gullible.

          I'm not promoting it. I'm discussing it in the hopes of removing some hype.
