All in the family: The complementary protective roles of spousal and other family support for Chinese immigrant mothers' life satisfaction over time.

The demand-resources model of stress posits that parenting tasks and expectations of mothers that exceed their resources are likely to tax their psychological well-being. Social and instrumental support from spouse or family may help alleviate the negative effects of parenting stress on mothers' psychological well-being. However, parenting stress and its impact have been less studied among immigrant mothers. Moreover, the sources of family support (i.e., spousal and other family members) might interactively affect mothers' well-being in the face of parenting stress. Therefore, the present study aimed to examine whether support from the spouse and other family members jointly buffers against the long-term psychological effects of parenting stress on Chinese immigrant mothers' life satisfaction. Data were collected from 273 Chinese American mothers at two time points separated by 6 months. A three-way interaction was conducted to examine the complementary protective effect of perceived support mothers received from their spouses and their other family members combined. Results showed that after controlling for the covariates, parenting stress was only longitudinally associated with changes in maternal life satisfaction when support from both spouse and other family members was low. Our findings highlight the complementary protective effects of spousal support and nonspouse family members' support in alleviating parenting stress of mothers and its adverse impact on lowering mothers' life satisfaction 6 months later. Theoretical and applied implications of these findings are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

To maintain or conceal one's cultural identity? Chinese American parents' ethnic-racial socialization during COVID-19.

Ethno-racially minoritized parents' ethnic-racial socialization may center on encouraging their children to maintain or conceal their ethnic-racial identity, particularly during the period of heightened racism of the COVID-19 pandemic. However, the underlying mechanisms that could explain Chinese American parents' specific ethnic-racial socialization practices and the role of children's developmental stage are not well understood. The present study examined: (a) the association between Chinese American parents' racial discrimination experiences and their engagement in maintenance of heritage culture and concealing Chinese heritage and connection ethnic-racial socialization; (b) the mediating and moderating roles of psychological well-being and family support; and (c) variations in these associations among parents with children of different developmental stages. The participants comprised 470 Chinese American parents (Mage = 43.7 years, SD = 6.4; 79% mothers) of 4- to 18-year-old children in the United States. Findings revealed that Chinese American parents' racial discrimination experiences were associated with greater engagement in both maintenance of heritage culture and concealing Chinese heritage and connection ethnic-racial socialization practices. Furthermore, parents' racial discrimination experiences were negatively associated with their psychological well-being, which in turn, was associated with lower levels of maintenance of heritage culture and higher levels of concealing Chinese heritage and connection ethnic-racial socialization practices. Greater family support buffered against the negative impact of racial discrimination on parents' psychological well-being and subsequent associations with their ethnic-racial socialization. The underlying moderated mediation mechanism was similar across parents of children, and younger and older adolescents. Our findings can guide future efforts to expand theoretical frameworks of ethnic-racial socialization among ethnic minority families. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Effects of erucic acid supplemented feeding on chronic doxorubucin toxicity in rats.

One of the undesired complications of the chemotherapy with doxorubicin is cardiotoxicity. Cardiac effect of erucic acid, which is a member of omega-9 fatty acid, is investigated on doxorubicin treatment in this study. Forty-eight rats were divided into eight groups and each group contained six rats. First group rats were fed with milk. In the third and fifth groups we fed rats with milk supplemented 0.5% and 5% erucic acid respectively. The groups 2, 4, 6 were fed as the groups 1, 3, 5 respectively; we injected 2 mg/kg twice weekly intraperitoneal doxorubicin to these groups whereas we injected isovolumous normal saline to the groups 1, 3, 5. Two other groups (groups 7 and 8) were fed with standard pellet. Group 8 received 2 mg/kg doxorubicin twice weekly; group 7 received normal saline. After 4 weeks hearts were isolated and mounted on a Langendorff apparatus perfused by modified Tyrode solution. Surviving rats were significantly less in erucic acid + doxorubicin groups at the end of the treatment period (p<0.05). No significant difference was found between groups for malondialdehyde, catalase, cytochrome c oxidase and isolated heart measurements. Concomitant application of erucic acid and doxorubicin showed profound toxicity.
