Direct observations in the home were not feasible given the large
catchment area from which patients were referred. To sample problem
behaviors in the home and to supplement more general parent ratings,
observations were obtained through the Parent Daily Report (PDR;
Chamberlain & Reid, 1987), which requires calling the parents daily.
At that time, a list of 23 specific behaviors was reviewed individually
with the parent, who noted whether the behavior occurred during the
previous 24 hr. Before treatment began, parents were interviewed at
the clinic to identify the antisocial child behaviors that occurred (Total
Problem Behaviors) and the subset that they viewed as especially problematic
for their child (Target Behaviors) among those included in the
PDR. At the end of treatment, the phone call procedure was explained
and an assessment schedule was agreed on. At each assessment period
(posttreatment and 1-year follow-up), 10 calls within a 2- to 3-week
period were scheduled to assess the daily occurrence of each behavior
on the PDR list. The PDR was mailed to those families without telephones
and completed for the 10 observation days. The number of calls
or observation days per assessment ranged from 6 to 10 (M= 9.6). The
measure yielded two scores: daily mean number of problem behaviors
and daily mean number of target behaviors each day (i.e., per call). The
PDR shows adequate internal consistency, test-retest reliability, intercaller
agreement, and moderate correlations (e.g
