The aim of the present study was evaluating the PERP and its subscales as mediator of the relationship between pregnancy planning and the prenatal psychological health. Numerous studies have been conducted in evaluating the relationship between pregnancy planning and prenatal mental health, as well as the relationship between social support and prenatal mental health [28]. But, as far as we know, the mediation of the PERP and the mental health of the woman during pregnancy was evaluated for the first time.
The results showed that the desirable the PERP, APE and RN decrease levels of depression and anxiety in the mother during pregnancy and also, mediate the relationship between pregnancy planning and the prenatal depression and anxiety. These results indicate that to moderate the stressful pressures following unplanned pregnancy, the positive partner's emotional reaction to the pregnancy is important.
Many studies have shown that the partner’s social support would decrease the woman’s levels of depression and anxiety during pregnancy [1, 23, 29] as well as the depression disorder [30];
Further, the level of the PERP level is well-established as a major predictive factor for depressive and anxiety in pregnant women.
These findings complement the results of research that showed an association between unwanted pregnancies and women's psychological health during pregnancy [13, 14]. It also confirms the results of studies that have shown that marital relationship affects the prenatal psychological health [31, 32].
Another finding of this study showed a positive relationship between planned pregnancy and the PERP. The results also showed that the depression and anxiety levels in pregnant women were inversely related to the PERP level. These findings suggest that unplanned pregnancy reduce a PERP level and thus affects the prenatal mental health. However, the lack of a direct effect of the pregnancy planning on depression and anxiety indicates that if a PERP would not decrease during unplanned pregnancies, an unplanned pregnancy will not increase the depression and anxiety of pregnant women.
Previous research has shown that unplanned pregnancies are accompanied by family disruption and a decline in the marital quality and couples' relationships; and it may associate with decreasing partner's emotional support and increasing risk of the women's depression and anxiety.
It was reported that the father's emotional reaction to the partner's pregnancy was one of major themes in the fatherhood development process [33]. As for the pregnancy of the woman, the father’s emotional reaction to pregnancy may be considered as messages of the fatherhood development and the partner's approval of pregnancy; and in this way, it may affect the mother’s mental health. Because, there was reported that unplanned pregnancy was associated with an increased probability of not approving the pregnancy [34]. Also, some studies showed that the partner's approval of pregnancy was associated with improvement of the woman's mental health and that the partner's disapproval would lead to depression and anxiety during pregnancy [2, 34].
Also, the present study showed that although the PERP level was less frequent among women with lower economic status, where the PERP in these families was perceived as a desirable reaction, the levels of depression and anxiety decreased in pregnant women. Therefore, it is necessary to teach the partner the skill of expressing positive reactions in families with lower socioeconomic status in order to improve the mental health of pregnant women in unplanned pregnancy.
Although in the present study, the partner's approval of pregnancy was not directly measured, the higher level of partner’s affect in the planned pregnancies confirms this explanation. But the lack of direct effect of the pregnancy planning and women's mental health may suggest that having a planned pregnancy is likely to affect women's mental health, when is followed by suitable partner's reaction.
Although, the present study showed that, apart from the socioeconomic status, the mental health of pregnant women depended on their perception of the PERP, in interpreting the results, there were some limitations that needed to be considered. The first notable limitation was that such factors as the partner’s personality characteristics could have affected the form of the couple’s relationship and probably the PERP level and women’s mental health. Further, because the data on the PERP and the woman’s mental health during pregnancy were collected in a cross-sectional study, we could not establish the temporal relation between the two conditions. The women’s mental health could have provoked a positive behavior in their partners and might have led to the partner’s positive emotional reaction to pregnancy. Also, depressed women would report more negative responses by their partners. Besides the mental disorders might have affected the perceived partner’s behavior in pregnant women; which in the cross sectional studies cannot be captured. However, measurement of relationship variables such as quality, length of relationship, and other family-specific variables such as time since last child (if other children), could improve future similar studies.
