The purposes of this cross-sectional study were to (a) determine the relationship between demographic characteristics of Jordanian registered nurses and theory of planned behavior concepts and (b) determine the relationships among theory of planned behavior concepts. One hundred fifty registered nurses of 250 were participated. Handwashing Assessment Instrument that assesses hand hygiene behavior, attitudes, and beliefs was used in this study.
Independent t tests and correlations were used to test hypotheses. Significant and positive correlations were found between intention to perform hand hygiene and the following variables: beliefs about outcomes, subjective norm, normative beliefs, and perceived behavioral control (r = 0.566, 0.444, 0.400, and 0.500), respectively.
Conclusions: Health education programs must be conducted to encourage hand hygiene behavior among Jordanian registered nurses who perceived their internal factors (eg, information, skills, and abilities) and external factors (eg, time, opportunity, and resources) to perform hand hygiene.
