It should be noted,
however, that essentially no empirical studies
of “sleep problems” in children have utilized these specific
clinical definitions. Rather, intervention studies have employed a
number of different research criteria (see below) that are closely related
to criteria for defining a sleep disorder but do not completely
parallel the diagnostic criteria to define “problematic” sleep onset
and maintenance-related behaviors. In addition, because bedtime
resistance and frequent night wakings commonly coexist, thus are
often “lumped” together for the purposes of defining inclusion
criteria for studies and assessing treatment outcomes.7 Furthermore,
most studies do not distinguish between bedtime resistance
and delayed sleep onset, which although often associated are not
always interchangeable in terms of etiology or treatment.
