The findings of the study indicated that 52 mothers with awareness mean score difference was 0.11, at pre-test 1.43, at post-test 1.54. The mean score change of the group (52 mothers) for the knowledge was 0.18, at pre-test 1.38 and at post-test 1.56. The mean score change of the group for the attitude was 0.17, at pre-test 1.50 and at post-test 1.67.The 156 family members with awareness mean score difference was 0.09, at pre-test 1.44, at post-test 1.53.
