A reversal (ABABAB) design was used to assess the effects of a verbal promp
t on safety belt use of restaurant patrons. A verbal prompt delivered by em
ployees at the exit door resulted in an average increase of 20% in safety b
elt use by drivers leaving the restaurant. A previous study provided this t
ype of antecedent immediately before supermarket patrons entered their vehi
cles. This effort demonstrates the effects of a verbal prompt with greater
latency between the prompt and target response.
