Comparing the results of behavioral observation of mothers and their children with the PLOC, the total score was found to be negatively correlated with child compliance Cr = .349, p < .01), and positively associated with negative talk (r = .346, 9 <.01), cry/yell ( = .276, p < .05), and the ECBI intensity score (Q = .259, p < .05) (Roberts et al., 1992).
Procedure
The fathers of the non-referred children were recruited through fliers placed in the community (i.e, recreational centers, video arcades, public libraries, day care centers). Fathers were also recruited through advertisements placed in the classified section of the Gainesville Sun newspaper and on the Cox Cable television bulletin. For fathers who responded to the advertisements, a brief telephone interview was conducted by the author to assess their eligibility for the study. If the father reported that English was the primary language in the home, that his child was between three and seven, and that neither he nor his child had a history of mental retardation, a screener for Oppositional Defiant Disorder was administered. If the child had no history of learning or behavior problems and received five or more "no" responses on the DSM-IV screener, an appointment at the Child Study Laboratory was scheduled at the family's convenience.
The administration of questionnaires and videotaping of observations of the nonreferred father-child dyads were conducted in a standardized manner by the author during one data collection session. First, fathers were administered the DSM-IV Diagnostic Interview for Oppositional Defiant Disorder. This interview was videotaped so that it could later be checked for reliability by an undergraduate assistant. Then, children were
