The current study sought to compare interventional materials intended to raise public awareness of the caregiving practices connected to Shaken Baby Syndrome (SBS). Two hundred and sixty four adults (mean age 32 years) were recruited for participation through convenience sampling at a large Northeastern university in the United States. Participants fell into two groups - those who regularly cared for children (46%) and those who did not (54%). SBS awareness was surveyed prior to an educational intervention and at three times points (2, 6, and 12 weeks post-intervention) longitudinally. Three intervention levels were used: two different video conditions, each with an informational brochure, and the brochure-only condition. Survey responses were combined into five factor scores. Changes in factor score over time were modelled using event history analysis to predict the conditional probability of change in awareness as a discreet event. The resulting models show consistent results for three of the five factors, predicting the highest likelihood of increased awareness for a teaching video intervention, followed by a testimonial video, and the lowest probability for increased awareness for the use of an intervention using only a brochure. Negative change, or decreased awareness, was not predicted by the type of intervention materials. Demographic variables were not significant predictors of either positive or negative change. The results indicate that the addition of video materials, and in particular material focusing on teaching alternative behaviours, significantly increases the likelihood of positive changes in SBS awareness over interventions which use only a brochure.
