Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q4 i? The omnibus test found no significant differences between the four superordinate diagnostic categories (learning disorders, behavioral disorders, intellectual disabilities, other), though intellectual disabilities yielded the descriptively most negative effect (g = −0.56). → Franz 2023 q4 i2 Fine-grained diagnostic subcategories differed significantly, with the most negative effects for combined intellectual and learning disability labels (g = −0.77) followed by combined behavioral and emotional disorder labels (g = −0.75). → Franz 2023 (2)

Evidence¶

Franz 2023¶

Franz, D. J., Richter, T., Lenhard, W., Marx, P., Stein, R., & Ratz, C. (2023). The Influence of Diagnostic Labels on the Evaluation of Students: a Multilevel Meta-Analysis. Educational Psychology Review. https://doi.org/10.1007/s10648-023-09716-6

q4 · i? · quant-synthesis · r2

Single-moderator analysis of diagnostic category in the multilevel meta-analysis of 284 effects. The omnibus test was non-significant; descriptively, intellectual disabilities (g = −0.56), learning disorders (g = −0.47), and behavioral disorders (g = −0.44) were all negative while the residual category (g = −0.17) was the only one not different from zero.

"Overall, we found no significant differences between the four superordinate diagnostic categories (k = 284, F (3, 280) = 2.43, p = .066, Fig. 2)."

Franz 2023 (2)¶

q4 · i2 · quant-synthesis · r2

Subcategory-level moderator analysis in the same meta-analysis; the overall test indicated significant differences between diagnostic subcategories, F(7, 276) = 2.30, p = .027, with combined intellectual-and-learning-disability labels most negative.

"with the most negative effects caused by combined intellectual and learning disability labels (g = −0.77), followed by combined behavioral and emotional disorder labels (g = −0.75)"

Discussion¶

Learner Variables¶

Learning Disabilities and Developmental Differences — predictor: learners who differ on it differ in outcomes

Diagnostic labels cause a moderately negative overall effect on how adults evaluate children (g = −0.42) — a broader claim this one bears on
Label effects are non-significant for attitudes toward the child, attributions of problem causes, and treatment-strategy evaluations — related
Type of evaluation moderates the label effect, with academic evaluations and overall assessments most negatively affected — related
