[The effectiveness of the video-based Lamaze method on prenatal mothers' knowledge, attitudes, and practice].

This study was conducted to explore the effectiveness of the video-based Lamaze method on pre-natal mothers' knowledge and attitudes, compared with that of traditional nursing guidelines. Using a quasi-experimental design, women in labor with gestations of 32 weeks or more were divided into four study groups, including two experimental groups (E(1): issued with traditional nursing guidelines and instructed in video-based Lamaze method; and E(2): instructed in video-based Lamaze method), and two control groups (C(1): issued with traditional nursing guidelines and C(2): issued with no guidelines). Before the intervention, E(1) had the highest score for knowledge. Scores for attitude showed no significant difference between the four groups. The experimental groups had higher scores than the control groups in the posttest. With the exception of the scores for attitude (E(1) > E(2)), knowledge (E(1): 13.09 +/- 1.40, E(2): 12.40 +/- 1.17) and management of the labor process (E(1): 119.00 +/- 10.91, E(2): 112.97 +/- 14.33) there were no significant differences between E(1) and E(2) in the posttest. Correlation analysis showed that the higher the scores for prenatal knowledge, the better the performance in prenatal practice, postnatal knowledge, attitude, and management of the labor process. The more positive the prenatal attitude, the better the performance in postnatal knowledge, attitude, and management of the labor process. The higher the scores in prenatal practice, the better the performance in postnatal knowledge, attitude, and management of the labor process. Positive associations were also found between postnatal knowledge, attitude, and management of the labor process. This study showed that the video-based Lamaze method is likely to promote more effectively than traditional guidelines the knowledge, attitudes, and practice of prenatal mothers in relation to giving birth. The use of this method in conjunction with traditional nursing guidelines may be even more effective in relation to maternal attitude.
