Sequences of staff-child interactions on a psychiatric inpatient unit.

Six psychiatry inpatients were observed during mealtimes to determine and evaluate staff intervention techniques. To extend and further elaborate the findings of a previous work (Pines, Kupst, Natta, & Schulman, 1985), staff behaviors (positive, punitive, isolating, and neutral) were investigated for their potential relationship to subsequent child behaviors (positive, negative, and inactive) via a lag sequential analytic approach. Staff punitive and isolating behaviors tended to be associated with significant increases in the likelihood of subsequent child negative behaviors and with significant decreases in child positive behaviors. Staff positive behaviors tended not to be related to a subsequent increase or decrease in any of the coded child behaviors. Findings demonstrate the utility of assessing conditional probabilities of sequences of staff-child behaviors in psychiatric inpatients.
