Abstract
|
|
|
This study was carried out to investigate the reliability between two retrospective surveys which was initiated with 71 women with spouses in November 1993 first and in December 1994, again. This study evaluated the level of correspondence by comparing pregnancy outcomes reported in the two surveys. The results of the study are as follows :
1) Of 173 pregnancv outcomes that have been investigated by two retrospective surveys. 118 cases(68.2%) were corresponded and 55 cases(31.8%) were contradicted each other in answering.
2) In answering of related to fetal death and induced abortion, a lot of data contradicted each other were observed. But the level of correspondence in live birth was high relatively.
3) In contradicted level the highest case was that after fetal death was answered in first survey answering was dropped in second survey.
4) This study examined levels of correspondance or not and factors related to a different answer, but there isn´t the possible explanation for such a pattern in responding.
