Abstract
Understanding the factors that make it more or less likely that healthcare practitioners (HCPs) will
perform certain patient safety behaviors is important in developing effective intervention strategies. A questionnaire
to identify determinants of HCP patient safety behaviors does not currently exist. This study reports the
development and initial validation of the Influences on Patient Safety Behaviors Questionnaire (IPSBQ) based on the
Theoretical Domains Framework.
Methods: Two hundred and thirty-three HCPs from three acute National Health Service Hospital Trusts in the
United Kingdom completed the 34-item measure focusing on one specific patient safety behavior (using pH as the
first line method for checking the position of a nasogastric tube). Confirmatory factor analysis (CFA) was undertaken
to generate the model of best fit.
Results: The final questionnaire consisted of 11 factors and 23 items, and CFA produced a reasonable fit: χ2 (175) =
345.7, p < 0.001; CMIN/DF = 1.98; GFI = 0.90 and RMSEA = 0.06, as well as adequate levels of discriminant validity,
and internal consistency (r = 0.21 to 0.64).
Conclusions: A reliable and valid theoretically underpinned measure of determinants of HCP patient safety
behavior has been developed. The criterion validity of the measure is still unknown and further work is necessary to
confirm the reliability and validity of this measure for other patient safety behaviors.
