Video modeling, Social Stories, and visual organizers produced the most beneficial gains in social communication skills, however only a small number of studies examined these methods making it "difficult to interpret the meaningfulness and generalizability of the outcomes.

Therefore, prompting may also be a promising technique for teaching social communication skills" (p. 144).
