The aim of the study was to determine if spontaneous play was altered
in 2-year-olds born to polysubstance-abusing mothers. The study is par
t of a longitudinal research project of chronic substance-abusing moth
ers and their children living in poverty in the inner city of Los Ange
les, identified in the hospital at birth by positive urine-toxicology
screens, and compared to non-substance-abusing mothers and their child
ren living in the same geographic area, of similar ethnic group and so
cioeconomic and marital status. The behavior of the 31 target and 21 c
omparison children in the 16-minute procedure was measured by frequenc
y counts of manipulative, functional, and symbolic acts as well as by
ratings of the quality of play. The play of the prenatally drug-expose
d children differed from the comparison group by demonstrating signifi
cantly more immature play strategies, less sustained attention, more d
eviant behaviors, and fewer positive social interactions with their ca
regivers.
