MetadataShow full item record
Objective: To determine the reliability and validity of a hand hygiene questionnaire (HHQ) developed to examine health care students’ hand hygiene knowledge, beliefs and practices. Design: Pilot testing of the HHQ Setting: Undergraduate students of nursing undergoing university education Subjects: The HHQ was administered to 14 student nurse volunteers in the ﬁnal year of their undergraduate degree and to another 45 volunteers following revision. Main outcome measures: Main outcomes measures were test-retest coefﬁcients, Cronbach’s alpha values and mean inter-item correlations of the scale items. Results: The face validity of the HHQ was high. Cronbach’s alpha values of 0.80, 0.74 and 0.77 were obtained for the Hand Hygiene Beliefs scale (HBS), the Hand Hygiene Practices Inventory (HHPI), and the Hand Hygiene Importance Scale (HIS) following removal of items with low item-to-total correlations or zero variance. The mean item-to-total correlations of the HBS, HHPI and IS were 0.37, 0.33, and 0.61 respectively. The two-week test-retest coefﬁcients for each scale were 0.85, 0.79 and 0.89 respectively. Socially desirable responding was identiﬁed in participants’ responses to the HBS using the 11-item short form of the Marlowe-Crowne Social Desirability scale. Conclusions: The HHQ demonstrated adequate reliability and validity and should be further tested on a wider sample of health care students.
