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].
