Using Urie Bronfenbrenner's ecological model as a theoretical
framework, Atzaba-Poria et al. (2004) sought to determine whether risk
factors operate in a cumulative manner in relation to behavior problems.
The researchers also sought to determine whether cumulative risk variables
at different ecological levels provide differential prediction of Externalizing,
Internalizing, and Total Problems scores on the CBCL, and whether the
findings would differ for English and Indian children living in West
London. Using the CBCL/4-18 (translated into Gujerati for the Indian
parents) to measure problems for 7- to 9-year-olds, the researchers
found that the more risk factors experienced by the child, the higher
the problem scores. Risk factors that significantly predicted Total
Problems came from the following three ecological levels: The individual
level (e.g., low IQ, high emotionality); the microsystem level (e.g.,
high parental negativity and harsh discipline); and the exosystem level
(e.g., low parental social support, low paternal marital satisfaction).
Externalizing problems were mainly predicted by cumulative risk variables
from the microsystem, whereas Internalizing problems were predicted
by cumulative risk factors from both the individual level and the exosystem
level. The predictive patterns did not differ significantly for English
versus Indian children. The authors concluded that "The support
for the cumulative hypothesis highlights the importance of having a
broad picture of children's characteristics and environmental components
when analysing children's adjustment. The distinct influence of risk
stemming from the different ecological levels suggests that the trajectories
of internalising, externalising and total problem behaviour may be different"
