A decade of programmatic studies of resistance during parent training
therapy is reviewed, including a brief description of a procedure deve
loped for coding resistant behavior. Analyses of sequential interactio
ns during treatment show that therapists' efforts to intervene produce
d immediate parental resistance. From baseline to midtreatment phases,
there were increases in the therapists' efforts to intervene, which w
ere in turn accompanied by increases in parental resistance. Contextua
l variables such as parent pathology also correlated with higher level
s of resistance. Decreases in resistance were associated with improvem
ents in parental discipline practices. Parental resistance altered the
behavior of the therapists, reducing their effectiveness. A regressio
n analysis shows that improvements in discipline predicted fewer futur
e arrests and out-of-home placement.
