Numerous strategies have been employed to examine ways to reduce the l
itter problem in society. However, the problem continues. Although the
research does not suggest a single ''cure-all'' method to eliminate l
ittering behavior, many simple, creative, and cost-efficient strategie
s have proven to be effective. This review examined 40 articles and 59
studies that employed either an antecedent or consequence strategy. O
f the 59 studies, 46 used antecedent techniques and 13 used consequenc
e techniques. Both strategies were generally effective in reducing lit
ter. The strengths, limitations, and general results of the techniques
were examined. Future research should include more utility analyses,
studies of the long-term effects of interventions, and large-scale int
erventions.
