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.
q3 i? Behavioral regulation was the intervention function for 51% of participants, versus joint attention (19%), social interaction (16%), or multiple functions (10%). → Ganz 2022
q3 i? Most studies focused only on communication production (k = 107) rather than comprehension (k = 5) or both (k = 6). → Ganz 2022 (2)

q3 · i? · quant-synthesis · r3
Descriptive synthesis of coded communicative functions across the 114 included studies. The article reports "the majority of the participants’ interventions involved communication functions of behavioral regulation (51%)" and calls this pattern somewhat problematic because behavior regulation is an easier target.

q3 · i? · quant-synthesis · r3
Coding of comprehension versus production outcomes across included studies. The article calls the near-exclusive production focus problematic, citing evidence that comprehension gains occur even when production is the intervention objective.
"Most studies focused only on communication production (k = 107), rather than comprehension (k = 5), or both production and comprehension (k = 6)."
Discussion¶
Related Claims¶
- Communicative function taught (behavioral regulation, joint attention, social interaction, or multiple) does not statistically moderate AAC effects — related
- Aided AAC interventions had large effects on targeted behavioral outcomes in individuals with ASD, per a meta-analysis of 24 single-case studies — related
- AAC interventions showed positive effects on all targeted behavioral outcomes, with greater effects for communication skills than other skill categories — related
