A multielement, alternating treatment design was used to compare the relative efficiency of backward and concurrent chaining strategies in teaching use of a fast food restaurant and a supermarket to four adults with moderate and severe handicaps. The results indicate that both strategies led to the acquisition and maintenance of the two training tasks. No significant differences were found in the number of training trials required for participants to acquire the targeted activities in the backward and concurrent chain training strategies. The results are discussed in terms of the implications for carrying out community-based instruction with individuals with moderate and severe handicaps.
