In the current study, the total stress level was found to be lower in OHSS women compared with the previous studies [13, 24, 25]. The fertility-related stress mean scores (139.6 ± 25.71) in OHSS women are slightly lower than the total fertility-related stress scores identified in past studies on women with assisted reproductive treatment. The rationale for the slightly lower scores in our study could be explained as follows. First, unclear causes of infertility and uncertainty about treatment outcomes were the main reasons for increased fertility stress in women [26]. In the current study, the participants completed a full round of embryo transfer and stayed in the reproductive ward with all professionals. The cause of the patient's infertility was identified before the transfer procedure, and the infertility specialist and nurses provided pregnancy monitoring, medication intervention, psychological care, and health education to reduce the stress level to some extent. It has been reported in earlier studies that positive coping styles helped reduce anxiety and depression levels, decreasing infertility-related stress in women undergoing IVF-ET or OHSS after ET for infertility [27, 28]. Therefore, health education on coping strategies was provided to the participants by the hospital's health professionals, which further contributed to a lower level of stress among participants.
The regression analysis findings indicated that the control variables, including demographic, social, and disease factors, accounted for 18.9% of fertility-related stress. The findings also highlighted that psychological capital and the three dimensions of couple communication patterns accounted for 9.4% of the variance of infertility-related stress. Furthermore, our findings suggested that both requested avoidance and complete avoidance couple communication patterns were positively associated with infertility-related stress in women with OHSS. In contrast, psychological capital was negatively related to infertility-related stress, which was in line with a previous study [29]. Gana and Jakubowska explained the impacting mechanism of negative communication between couples on infertility-related stress [30]. They highlighted that the negative communication significantly affected relationship quality and marital happiness and caused severe consequences for the physical and mental health of OHSS women.
The correlation analysis of the current study showed that communication patterns were correlated with infertility-related stress, which was consistent with the findings of previous studies [31]. However, the current study found no significant correlation between constructive communication patterns and infertility-related stress. This finding was inconsistent with Falconier et al. reported earlier [32]. The difference in findings may account for the difference in the treatment phase. Their study was conducted among women initial phase of treatment when they were diagnosed with infertility. They found that positive communication helped reduce infertility-related stress by building trust and relationships between couples[32]. But the present study was conducted at a later phase of treatment, and the study population was post-ET women. Therefore, the present study's findings are important to understanding the association between constructive communication and infertility-related stress among post-ET women. The findings suggest that infertile women in the different phases of infertility treatment needed different coping strategies for infertility-related stress. However, more research is needed to confirm this relationship between constructive communication and infertility-related stress in post-ET women.
The survey also analyzed the psychological capital based on four dimensions: self-efficacy, hope, optimism, and resilience [22]. It is assessed as a positive state of mind that an individual exhibits during dealing with a difficult situation [33]. Psychological capital facilitates positive thinking and positive actions to overcome difficult situations and achieve a better way of life [34]. In recent years, psychological capital has attained much attention in research and is considered a crucial element of positive psychology [34]. A previous study highlighted that psychological capital was an essential resource for an individual coping with infertility-related stress and facilitating a positive state during treatment [29]. It is also established from past studies that post-ET women have higher levels of psychological capital and lower scores of infertility-related stress, which indicated that psychological capital helped them recover quickly and deal with challenges of daily life and illness discomforts [29, 35].
Ni et al. reported that the extent of psychological capital had a protective impact on infertility-related stress and other emotional and behavioral problems in women [36]. The findings in the current study were also aligned with the past studies. Findings revealed a mean psychological capital score of 4.65 ± 0.727 in OHSS women, and the level of psychological capital was found to have a significant negative correlation with infertility-related stress. Along with physical challenges (e.g., hemoconcentration, decreased blood volume, and chest and abdominal fluid), the infertile women also experience several family issues. The primary family issues that impact OHSS women’s psychological capital include the high cost of treatment, disturbance in the family, lack of positive communication and support from spouse, social stigma, and doubts in treatment results. These findings suggested that clinical treatment to improve the extent of psychological capital could improve individuals' ability to deal with social pressure, sexual pressure, and the thoughts of parental roles leading to a decrease infertility-related stress. In recent years, there have been many attempts at psychological capital intervention programs, including training in positive thinking, biofeedback training, and emotional resilience group training, but their effectiveness in OHSS women has yet to be investigated in future studies [37].
The current study's findings also highlighted that the requested avoidance of couple communication patterns mediated the association between psychological capital and infertility-related stress. In contrast, the other two communication patterns had no statistically significant association with infertility-related stress. Requested avoidance of communication refers to complaints, criticism, blame, and other negative ways of communication between couples [31]. Our findings further supported the findings of the previous studies [32, 38]. Lam et al. reported that the requested avoidance communication induced a higher stress level by decreasing the psychological capital [38]. Falconer and Epstein stated that couples engaging in “silent treatment” as an attempt to end the discussion, change the subject, or leave the scene of the conflict, could destroy a couple's relationship and intimacy, intensifying the stigma of infertility that women experience could result in a higher level of infertility-related stress [32].
Furthermore, the higher levels of mental stress negatively affect the treatment outcomes and pregnancy rate during infertility treatment [39]. Nevertheless, the mediating effect of the request avoidance communication on psychological capital could significantly provide significant support to OHSS patients dealing with infertility-related stress. The findings suggest that changes in the communication patterns between the couples increase the psychological capital, thus leading to a lower infertility-related stress level.
