The current study adopted an interdependent approach to construct a mediation model that examined the effects of parental PS on adolescent DS through the mediating effects of overt and covert parental CCB in China. Paternal PS was related to adolescent DS through the mediating effect of paternal overt CCB. Maternal PS was related to adolescent DS through the mediating effects of paternal overt CCB and maternal covert CCB. Overall, maternal PS exerted a more substantial influence on adolescent DS than paternal PS. The study supplemented understanding of the relationships and mediating mechanisms between parental PS and adolescent DS, which promotes the targeted family intervention programs.
Consistent with the parental stress model [
1,
2], our study supported that parental CCB constitutes a crucial mediating mechanism in the relationship between parental PS and adolescent DS. Stressed parents have tended to respond to parenting stimuli negatively due to excessive anxiety and worry [
11], thus, they may not be able to provide an optimal interpersonal environment for children [
11]. With elevated parental PS, the parent may become dissatisfied with the other parent, demonstrate disrespectful attitudes, blame the other parent’s mistakes, and complain to the child. When struggling with parental PS, parents may be more likely to become involved in interparental conflicts due to energy depletion. Exposure to coparenting conflicts during daily interactions contributes to the risk of developing DS in adolescents.
Only fathers’ overt CCB and mothers’ covert CCB demonstrated significant mediating effects on the relationship between parental PS and adolescent DS. This may be due to the tendency of children to hold different expectations and interpretations of their fathers’ and mothers’ behaviors [
34]. As adolescents grow older, they may become more sensitive to and less tolerant of fathers’ stressed behaviors [
74]. Since families may expect mothers, as the primary caregiver, to take the main responsibility of parenting at home, mothers may have more opportunities to develop a stable emotional bond with children and show disparaging behavior toward them [
38]. If the mother undermines the father when alone with the child, the child’s consistent and positive view of the family may be negatively influenced. In particular, the child may feel distant toward both parents and experience more negative emotions when the mother disparages the father’s absence [
55,
74].
It is mainly maternal PS that influences adolescent DS through paternal and maternal CCB. In our study, maternal PS was more strongly related to paternal overt and covert CCB than paternal PS itself. This may be explained by the fathering vulnerability hypothesis [
49]. The father’s parenting is more likely to be affected by other factors than the mother’s, thus demonstrating higher susceptibility to external stressors [
12,
49]. This may be because fathers are less clearly defined by social conventions than mothers, which makes fathering more vulnerable to external influences [
12,
49]. Our study also found that maternal PS could influence adolescent DS through paternal CCB, but paternal PS could not influence adolescent DS through the mediating effects of maternal CCB.
Although we have included parents’ age [
57], SES [
58], and educational levels as controlling variables, other critical contextual factors that may influence parental PS and coparenting conflicts, such as employment, work status, and work-and-family conflicts [
23] during the lockdown period, have not been controlled. Previous research has indicated the importance of a variety of contextual factors (e.g., work hours and conflict of work and family) for parental PS [
33,
45] and coparenting conflicts [
53]. For example, a recent study [
23] revealed that the feasibility of remote working acted as a key influential factor for parental PS among the pandemic-related contextual factors. The work-family balance may constitute a conspicuous challenge for parents during the lockdown that may hamper parental PS, which might impact coparenting [
23].
Moreover, the status of work from home might influence the gendered division of housework and childcare and thus differentially impact parental PS for fathers and mothers. A recent study [
16] found that when both parents worked at home, although fathers’ family involvement increased, this would not change the gendered phenomenon of household work, as mothers also tended to contribute more time and energy to household activities. When neither parent or only the mother worked at home, mothers might also become the main force in charge of the extra caring and schooling of children [
16], remaining gendered responsibility. Another recent study [
72] also found that mothers have carried a heavier load than fathers in childcare during the pandemic, even while they are still working. However, it seems that mothers’ working status only has a limited influence. Under stressful circumstances, mothers tended to reduce their working hours to balance the childcare demand divisions. Moreover, working mothers are more likely to transition out of employment due to childrearing. Researchers [
13] have revealed that compared to the father, a working mother is more than four times more likely to decrease their work hours for childcare, indicating the challenges of the pandemic to mothers’ employment and the unequal domestic division of labor. Although these studies [
13,
16,
72] did not reveal the direct relationship between work status and parenting PS and coparenting, they indicated the difference in paternal and maternal PS and the increased possibility of coparenting conflicts due to gendered divisions of housework. Therefore, future studies might examine work-related variables during the pandemic and control them in the analysis to explore the associations between parental PS, parental CCB, and adolescent DS.
Moreover, as a limitation of our study, other risk factors have not been included in our study. Indeed, parents and adolescents have encountered contextual, family, interpersonal, individual, and other multiple factors during the pandemic. Researchers [
22] have posited that families have been exposed to a series of stressors, such as work and financial disruptions, social isolation, school and childcare closures, and shelter-in-place isolation brought by the pandemic in a comprehensive model. These multiple risk factors would lead to disruptions of parents (stress, financial strain, and mental health), which would then affect individual parenting and coparenting quality [
22], and finally influence child adjustment (mental health, emotional security, and behavior problems). Empirical studies have also suggested the various influences of contextual factors such as “work status” [
23] and “SES” [
58], family factors such as “household chaos” [
58], interpersonal factors such as “marital status” [
30], and “individual factors” [
15,
30,
64] on parental PS, coparenting, and adolescent adjustments. Therefore, future research might explore the influences of other risk or protective factors on parental PS, coparenting, and adolescent adjustments, or the associations after taking multiple influential factors into account.
Finally, this study was conducted during the lockdown period in China. It should be noted that some empirical studies have pointed out the detrimental effects of restricted activities on families [
47,
58]. For example, a study conducted during the lockdown [
58] showed that the lockdown could increase parental PS levels to some extent, and it is pretty stressful for parents to achieve a balance between life, work, and childcare in the absence of other social help during this particular period [
58]. A recent study [
22] found a large deterioration in the magnitude of within-individual change in parent and child mental health in the first months of the pandemic compared to before. Moreover, researchers [
22] pointed out that coparenting and individual parenting quality also tended to decline during this period. Based on the results, researchers have emphasized the need for intervention programs to provide more support and guidance and thus prevent families from potential “scarring,” which could be regarded as a prolonged and intertwined individual and family problems. Another study [
47] recorded changes of parents over the first 1.5 years of the pandemic and compared measurement results before and within two mandatory lockdowns during the pandemic. The findings showed that parents displayed elevated DS, reduced well-being, and poor physical health; poor cohesion in family ties and more chaos, but no obvious change in the parent–child relationship and parenting practices. Importantly, partner support as a buffer could protect family functioning from the adverse effects of the lockdown.
Overall, elevated mental health problems and decreased family functioning emerged in families faced with multiple risk factors [
7,
8] during the pandemic, but some families could also achieve resilient outcomes by adapting to these changes [
18,
47,
50]. For example, one study revealed no change in couple relationship satisfaction from shortly before to shortly after the pandemic [
69]. Moreover, another study adopted mix-methods to investigate the influence of the pandemic on adolescent parents [
3]. While the qualitative analysis of 21 adolescent parents revealed more adverse effects of the pandemic, such as economic and health stress [
3], the quantitative analysis showed that the pandemic-period cohort also demonstrated fewer DS, parental PS, more positive coparenting communication, and conflict management than the similar pre-pandemic cohort counterparts from the same school [
3]. By adopting mixed methods in a sample with relatively good SES, researchers [
18] found that families still encountered challenging struggles in various life domains from May to July 2020, indicating significant associations between the pandemic’s daily impact and elevated psychological distress for children and parents. However, some families still exhibited resilience and achieved certain levels of positive outcomes. Some resilience factors, such as family routines, family relationships of high quality (marital, parent–child, and coparenting), and constructive problem-solving [
40,
50] could help families better respond and adapt to challenges during stressful times. Intervention programs should consider resilient factors that could mitigate and help families recover from the adverse effects.
Nonetheless, this study also contributed to knowledge about family adjustments during the pandemic. The current study demonstrated the need to simultaneously distinguish and investigate fathers’ and mothers’ parenting-related variables. Within the parental stress model framework, we tried to illuminate specific mechanisms whereby parental PS would flow to adolescent DS. The results revealed that the parent’s gender and individual PS interacted to affect adolescent DS. Maternal PS exerted a more substantial effect on adolescent DS than paternal PS. Maternal PS could also spill over and cross over into maternal covert CCB and paternal overt CCB, which would then influence adolescent DS. However, paternal PS could only spill over into the father’s overt CCB and influence adolescent DS.
