Overall, Tiwari and colleagues (2005) found mixed results with regard to the effects of the empowerment training. For pregnant women in the experimental group, there were statistically significant declines in levels of psychological abuse, minor physical violence, physical functioning, physical and emotional role limitation, and postnatal depression. However, there were no statistically significant effects on severe physical violence, sexual abuse, social functioning, and mental health. Overall, the preponderance of evidence suggests the program had the intended effects on participants.
Study 1
Postnatal Depression
Statistically significantly fewer women in the experimental group had clinical levels of postnatal depression at follow-up, as measured by the Edinburgh Postnatal Depression Scale. After the intervention, nine women from the experimental group showed signs of postnatal depression, compared with 25 in the control group.
Psychological Abuse
There were statistically significantly lower levels of psychological abuse as measured by the Conflict Tactics Scale (CTS) for the experimental group, compared with the control group.
Minor Physical Violence
There was a statistically significantly lower levels of minor physical violence as measured by the CTS for the experimental group, compared with the control group.
Severe Physical Violence
There were no statistically significant differences between the two groups in severe physical violence as measured by the CTS.
Sexual Abuse
There were no statistically significant differences between the two groups in sexual abuse as measured by the CTS.
Physical Functioning
There were statistically significant differences favoring the experimental group, compared with the control group, in physical functioning as measured by the Short Form Health Survey (SF-36). Higher scores indicated a higher health-related quality of life. The average score for the experimental group for physical functioning was 90, compared with the average score of 80 for the control group.
Physical Role Limitation
There were statistically significant differences favoring the experimental group, compared with the control group, in physical role limitation as measured by the SF-36. The average score for the experimental group for physical role limitation was 73, compared with the average score of 45 for the control group.
Emotional Role Limitation
There were statistically significant differences favoring the experimental group, compared with the control group, in emotional role limitation as measured by the SF-36. The average score for the experimental group was 77, compared with the average score of 47 for the control group.
Social Functioning
There were no statistically significant differences between the experimental and control groups in social functioning as measured by the SF-36.
Mental Health
There were no statistically significant differences between the experimental and control groups in mental health as measured by the SF-36.
