The Observer Effect and Its Impact on Staff Behavior in an Acquired Brain Injury Neurobehavioral Treatment Setting

Abstract

Staff in three neurobehavioral residential settings (5 in each residence for a total of 15 staff) were trained on specific positive interaction behaviors in a multiple baseline design. Staff in each of the residences were provided with recommended behaviors for interacting with residents through an observational procedure where they observed and completed checklists on video models of the targeted staff interaction behavior. In addition to staff interaction behaviors, subsequent levels of adaptive resident behaviors were also examined, such as active engagement and indices of happiness. Targeted interactions increased from an average of 7.2% of intervals during baseline to 80% during the intervention. Productive involvement engaged in by residents increased from 17.9% in baseline to 73.9% during the intervention, and the happiness indices of residents increased from 6.1% in baseline to 67.5% during the intervention.
