Over the past decade, numerous groups of researchers have studied the willingness of health care personnel (HCP) to respond when a disaster threatens the health of a community. Not one of those studies reported that 100% of HCP were willing to work during a public-health event (PHE).

The objective of this study was to explore factors associated with the intent of HCP to respond to a future PHE.

The theory of planned behavior (TPB) framed this cross-sectional study. Data were obtained via a web-based survey from 305 HCP. Linear associations between the TPB-based predictor and outcome variables were examined using Pearson's correlations. Differences between two groups of HCP were calculated using independent t tests. A model-generating approach was used to develop and assess a series of TBP-based observed variable structural equation models for prediction of intent to respond to a future PHE and to explore moderating and mediating effects.

The beginning patterns of relationships identified by the correlation matrix and t tests were evident in the final structural equation model, even though the patterns of prediction differed from those posited by the theory. Outcome beliefs had both a significant, direct effect on intention and an indirect effect on intention that was mediated by perceived behavioral control. Control beliefs appeared to influence intention through perceived behavioral control, as posited by the TPB, and unexpectedly through subjective norm. Subjective norm not only mediated the relationship between control beliefs and intention, but also the relationship between referent beliefs and intention. Additionally, professional affiliation seemed to have a moderating effect on intention.

The intention to respond was influenced primarily by normative and control factors. The intent of nurses to respond to a future PHE was influenced most by the control factors, whereas the intent of other HCP was shaped more by the normative factors. Health care educators can bolster the normative and control factors through education by focusing on team building and knowledge related to accessing supplies and support needed to respond when a disaster occurs.
