ABSTRACT
T scores are similar to z-scores, as both are standardized ways to show where an individual score falls in relation to the mean of a distribution. T scores are most often used with standardized tests as part of psychological and educational assessment. In developing a standardized test, researchers give their test to a large sample and see how the sample performs. T scores help to make the comparisons between the norm group and later test takers. The immediate and long-term effects of a Parent-Child Interaction Therapy-derived program offered at a Kaiser Permanente [HMO] facility were evaluated. Data were gathered from a Northern California Kaiser Permanente, serving a mostly middle-class, suburban community. Participants were self-referred or referred by their pediatrician or school due to problem behaviors Eyberg Child Behavior Inventory (ECBI). This self-report measure has two scales: The Intensity Scale measures the frequency of misbehavior; the Problem Scale measures the number of behaviors the parents identify as a problem for them.
