The large sample, inclusion of multi-informant data,
and simultaneous consideration of several latent variables
are strengths of the current work. Using both parent
and child perspectives in defining the latent variables
increases the likelihood of measuring the intended construct,
while placing these constructs within a single
model helped better define the complex relationships
that contribute to functional disability in children with
FGIDs. In addition, the inclusion of two different ways
of measuring functional disability allowed for replication
of model testing that enhances confidence in the relationships
identified.
