2018
Background: ZIKA virus is a known public health emergency of international concern. The mass gathering places like Hajj are the most viable environment for transmission of such virus.
Aim of the work: this study aimed to determine the reliability, validity and conduct the field testing of the field testing of Arabic version of WHO-KAP questionnaire.
Material and Methods: this was across-sectional study in which the Arabic version of WHO-KAP questionnaire was tested in the field of Al-Hajj season in 2017 by using multistage clustering sampling method and retested online in the period from 23rd of August, 2017 till 20th of September, 2017.
Results: a total of 399 pilgrims from 11 countries were included with 61.4% that were females. The age of the subjects ranged from 16 to 56 years old with means of 23.47± 14.19 and 15.49± 16.87 for males and females, respectively. Internal consistency was measured using Alpha Cronbach's test which was 0.858. Test reliability was measured by Intra Class Correlation Coefficient (ICC) that was 0.858. Kaiser-Meyer-Oklin Measure of Sampling Adequacy (KMO-test) was done and showed a significant change (p-value= 0.0001). KMO measured 0.871 which indicated a sufficient data to conduct the Factorial Analyses. Bartlett’s Test of Sphericity (Approximate Chi-square = 12714.212 , df =1485, p = 0.000). Loading of items of WHO-KAP were >0.4 which led to preservation of all the chosen items.
Conclusion: the Arabic version of WHO-KAP questionnaire had good internal consistency. It can be used in the future as field test.
