Purpose
– The purpose of this paper is to determine which constructs (factors) will significantly predict and influence the intention to complete a health risk assessment (HRA) in a hospital employee population.
Design/methodology/approach
– The authors used a cross-sectional design using the theory of planned behavior to design a questionnaire to determine the variables associated with intention to complete an HRA. From a sample of those who completed (n=17) and those who did not complete (n=16) the HRA, the authors used elicitation inquiry to determine the leading factors associated with the intention to complete an HRA. The authors used the responses from this inquiry to develop a questionnaire for a hospital population (n=1,550). A total of 503 hospital employees completed and returned this questionnaire. Using the returned questionnaire data, the authors used logistic regression analysis to determine the best fit model for predicting intention to complete an HRA.
Findings
– The predictive model was statistically significant at the p
<
0.001 level. Discriminant analysis correctly verified the predictive model classified intenders and non-intenders the majority (84 percent) of the time. These study results indicated that perceived behavioral control factors such as having time to complete the HRA, confidence in completing the HRA and trust that the information divulged in the HRA would be kept confidential had the strongest influence (OR=5.39) in predicting participation in taking an HRA.
Research limitations/implications
– Potential limitations of this study include; response and selection bias, homogeneity for age and sex and generalizability. These results help to identify key behavioral-related factors predicting hospital employee participation to complete an HRA.
Practical implications
– Administrators of worksite health promotion programs can systematically explore means of addressing identified participation barriers for the purpose of increasing overall HRA participation success beyond financial incentives.
Originality/value
– The HRA has become a widely accepted assessment tool used to help mitigate the rise in chronic disease. However, HRA completion rates are reported to be low to moderate with very limited research focussed on factors predicting HRA participation.
