From various points of view, marriage is considered among the most important events occurring in people’s lives (
16). Without any doubt, marriage is a critical stage in personal and social development of everyone. Children of patients with mental disorder establish their lives based on cultural norms of the society and the beliefs they have experienced concerning mental illness. This process has an important role in development of the concept of their lives’ most vital events such as marriage. Our participants’ experiences revealed that although marriage is considered as a normal trend in our lives, it is assumed as a big challenge for children of parents with mental illness. Several studies have shown that the rate of marriage for children of parent with mental illness is less than those with healthy parents (
17). Many people are not willing to marry such children. The findings of the present study revealed that the most important reason for other people to avoid marrying such persons is their fear of heredity status of their illness and the possible transfer of disorder to their own children. In connection with the occurrence of such event, some studies have shown that these disorders can be genetically transferred to children. The participants mentioned their unpleasant experiences of their parent’s illness and the fear of having the disorder passed to their children. This anxiety is so deep that some children mention that they never decide to marry; this finding was also reported in other studies. This problem was present for all participants regardless of their sex. In addition, talking about marriage is rather difficult for many of these children due to their parents’ illness. The participants predicted a gloomy perspective for their marriage considering their parents’ mental disorder, and as a result, are not willing to discuss about marriage because they do not want to share this depressing horizon with other people. On the other hand, these children are also embarrassed to talk about their parents’ illness during prenuptial marriage meetings. Moreover, the experiences of some participants revealed that choosing or being chosen as a marriage partner is very difficult for these children. Setting aside the prenuptial problems, children who succeeded to marry, still have to suffer challenges (originated from this problem) with their spouses and their families. Accepting the fact of mental disorder in some families is not easy; this gives rise to some troubles during family incidence and marital problems and leads to some family arguments or annoyance. This is an instance of a family picture, which has been frequently observed and admitted by the children of parent with mental illness in their lives or their siblings’ lives.
Fear of developing the parent’s mental illness was found to be the predominant cause of anxiety. This is of particular importance as the literature has frequently acknowledged the risk of intergenerational genetic inheritance of mental illness (
18); however, the participants of the current study also expressed fear of transmitting their own negative behaviors to their children. The anxiety of living with a parent with mental illness is too great that some children explained they do not want to marry or have children out of fear of making their own child live with such anxiety. In one case, toxic inheritances (i.e., stories given to children from family members or others that can turn out to be lies or distortions) were used to determine this type of anxiety (
19).
Parental mental illness poses a major problem for many children and this can seriously affect their social, physical, and emotional well-being. The findings of our study highlighted the issues surrounding the marriage of children of parent with mental disorder. These findings can be used for delivery of care to these children. If the health care providers intend to plan a holistic approach for the family of a parent with mental illness, the children must be given a specific position. In this approach, the issue of marriage and its challenges should also be considered as an important topic. Such programs provide many benefits for both the parent with mental illness and the children while reducing the cost of care services within the health care system (
20). As our findings are subjective in nature, their application in other contexts should be made cautiously. For generalization purposes, similarity between contexts must be considered. Some children refused participation in the study, leading to further limitations. Although the data were saturated, a greater number of participants could increase the depth of the data.
