A One-Group Pretest-Posttest Design was used to find out the effect of Health Education on MAAP among 126 primigravida mothers selected conveniently residing at urban region of Maharashtra state.

To collect data on demographic variables & knowledge regarding MAAP, a self-administered questionnaire was used among primigravida mothers before and after Health Education. After a pre- test, Health Education on MAAP was administered among primigravida mothers. However, after one week, a post-test was conducted among primigravida mothers to assess the effect of Health education on MAAP.

From the findings, it was observed that whereas no mother had good and very good level of knowledge prior to the intervention, the percentage of mothers with very good knowledge increased to 31.4% after the MAAP. Similarly, after intervention, the number of mothers with Good level of knowledge rose up to 43 (42.1%%) from 0 (0%). However, the mothers with average knowledge rose to 23.8% from 12.7%. Further, it is seen that after intervention none of the mothers had poor and very poor knowledge. There was about 40.2% improvement in knowledge among mothers after MAAP. There was a significant difference (p<0.0001) between pre-test and post- test knowledge scores.

Chi- square test was used to find out the association between post-test knowledge scores on prevention of behavioral problems in children and selected demographic variables of Primigravida mothers. The finding of Chi-square test value shows that there is no significant association (p>0.05) between post-test knowledge scores and selected demographic variables like Age in years, Education, Occupation, monthly income, religion, and source of information.
