The
Mediating Role of Language in Relations between Social Cognition
and Externalizing Psychopathology: Findings for Children Seen
in Canadian Clinics
Previous studies have shown that
interventions designed to improve social problem solving may be
followed by reductions in externalizing behavior problems. However,
to be helped by these interventions, children need to understand
verbal communication and to express themselves verbally. Canadian
researchers sought to test the following hypotheses regarding relations
between syntactic language, social cognitive development, and externalizing
psychopathology: Hypothesis 1 was that syntactic language mediates
the effects of social cognitive maturity on externalizing psychopathology.
Hypothesis 2 was that syntactic language and social cognitive development
independently affect externalizing psychopathology (Zadeh, Im-Bolter,
& Cohen, 2007). Tests of syntactic language and of social cognition
were administered to 354 English-speaking but ethnically diverse
7- to 14-year-olds who were referred to mental health clinics in
the Toronto area. The CBCL was completed by parents and the TRF
by teachers. Controlling for age and working memory scores, structural
equation modeling (SEM) yielded better fit for the mediation model
specified by Hypothesis 1 than for the direct effects model specified
by Hypothesis 2: With both CBCL and TRF Externalizing scores included,
the best-fitting model showed that associations of social cognition
with Externalizing scores were mediated by language functions. However,
the authors cautioned against drawing causal conclusions, as the
study was cross-sectional. They concluded that "Although the
model fit indices indicated a very good fit to the data, the current
study represents the first to examine language as a mediator of
the association between social cognition and externalizing psychopathology,
and as such, the model needs to be cross-validated with different
samples" (p. 150).
