Gm. Pace et Ea. Toyer, The effects of a vitamin supplement on the pica of a child with severe mental retardation, J APPL BE A, 33(4), 2000, pp. 619-622
The effects of a common multiple vitamin on the pica of a child with severe
mental retardation and anemia were evaluated. A BAB design revealed that p
ica was decreased by the vitamin. The results suggest that pica can be effe
ctively treated by implementation of a simple nutritional or biological int
ervention. Further research investigating the generality of this finding an
d the effects of combining biological and behavioral interventions are disc
ussed.
