Results:
The study included 201 subjects; they were 118 (58.7%) males and 83 (41.3%) females. All of them completed the pre-interventional and post-intervention questionnaire (Appendix II). A comparison of their socio-demographic characteristics is shown in Table 1. We found there is no significant differences between the two groups regarding gender, age groups, nationality, and educational level.
Table 2 shows the differences in lumbar puncture knowledge and risk perceptions pre- and post-education. Within the verbal explanation counseling group, the mean for the self-reported knowledge for LP showed significantly higher post-education scores compared to the pre-education scores (45.78 14.58 versus 20.72 ± 18.1 with p < 0.001). Similarly, within the video guided counseling group, there were significantly higher post-education mean scores for the self-reported knowledge of LP (42.46 ± 18.94 versus 19.32 ± 18.3 with p < 0.001). On the other hand, the mean score for LP risk perception showed significantly higher pre-education mean scores (6.5 ± 4.51 versus 8.2 ± 3.59) with p < 0.001).
Table 3 shows a comparison of pre-and post-education mean scores of lumbar punctures consenting and perceived risks in both groups. Responses of both groups regarding the question related to their previous consent for LP for themselves or their siblings did not show any significant differences. However, answers to the question of LP can have serious side effects showed significant more answers for strongly agree and agree in the post-education video-guided counseling group compared to the verbal counseling group [9 (7.6%) versus 2 (2.4%) and 34 (28.8%) versus 10 (12%) respectively, with p-value 0.016 for both]. On the other hand, the answers with disagreeing showed significantly more answers in the pre-education group [41 (49.4%) versus 41 (34.7%) with p-value 0.016].
