Effect size for polynomial contrasts

Is there a way to compute and effect size for polynomial contrasts (quadratic contrast, to be more precise)?

Thank you!

What do you mean by "compute an effect size"? Are you referencing something beyond the generated model coefficient?

The coefficients are their effect sizes. Also, do you want a single estimate for each term or an overall estimate?
