This study examined statistically the differential relationships among child domain and parent domain scores of the Parenting Stress Index (PSI) and child disruptive behaviors as measured by the problem and intensity scales of the Eyberg Child Behavior Inventory (ECBI). As were 165 children ages 2-10 referred for psychological evaluation. The PSI child domain and parent domain scores were significantly correlated with the ECBI intensity and problem scores and, as hypothesized, child domain scores were significantly more highly correlated with ECBI scores than were parent domain scores. Correlations of the ECBI problem and intensity scores with the PSI were not significantly different. In contrast to a pervious study, no differences were found between single- and two-parent families in the number of disruptive child behaviors reported as problems. Analyses of sample differences suggested that, as the frequency of children's disruptive behaviors increases, spouse support may be less effective in buffering m...
