The reciprocity and variation of values and beliefs are dynamic features of the parent-child relationship. Parents and adolescents may hold congruent or incongruent views regarding the malleability of socioeconomic status (mindset of SES), potentially influencing adolescents’ psychological and physiological stress outcomes, as reflected in stress perceptions and the hypothalamic–pituitary–adrenal (HPA) axis functioning. The current study investigated how patterns of parent-adolescent congruence and incongruence in mindset of SES were associated with adolescents’ perceived stress and diurnal cortisol patterns four months later. A total of 253 adolescents (M_age = 12.60, 46.2% girls) and their parents (M_age = 40.09 years, 59.5% mothers) participated in this study. Polynomial regression analyses and response surface analyses showed that adolescents perceived lower levels of stress when they themselves or their parents reported a stronger growth mindset of SES. Additionally, adolescents with a stronger growth mindset of SES also exhibited a steeper diurnal cortisol slope. Moreover, parents’ mindset significantly interacted with adolescents’ mindset to influence adolescents’ diurnal cortisol patterns such that when adolescents hold weaker growth mindset of SES, those with higher parental growth mindsets had significantly higher cortisol awakening response and steeper diurnal cortisol slope. Furthermore, adolescents who showed incongruence with their parents but had averagely stronger growth mindsets of SES reported a significantly steeper diurnal cortisol slope than those who had averagely weaker growth mindsets with their parents. The findings point to the beneficial impacts of the growth mindset of SES on stress-related outcomes among adolescents, as well as the significance of considering both parents’ and adolescents’ mindsets when exploring these associations.

价值观和信仰的互惠性和变化是亲子关系的动态特征。父母和青少年可能对社会经济地位的可塑性（SES 心态）持有一致或不一致的看法，这可能会影响青少年的心理和生理压力结果，如压力感知和下丘脑-垂体-肾上腺 (HPA) 轴功能所反映的那样。目前的研究调查了父母与青少年在 SES 心态上的一致性和不一致模式如何与四个月后青少年感知的压力和昼夜皮质醇模式相关。共有 253 名青少年（M_年龄 = 12.60，46.2% 女孩）及其父母（M_年龄 = 40.09 岁，59.5% 母亲）参与了这项研究。多项式回归分析和反应面分析表明，当青少年自己或父母报告有更强的 SES 成长心态时，他们感受到的压力水平较低。此外，具有较强SES成长心态的青少年也表现出更陡峭的昼夜皮质醇斜率。此外，父母的心态与青少年的心态显着相互作用，影响青少年的昼间皮质醇模式，当青少年的SES成长心态较弱时，父母成长心态较高的青少年的皮质醇觉醒反应显着较高，昼间皮质醇斜率较陡。此外，与父母表现出不一致但平均具有较强SES成长心态的青少年报告称，与那些与父母平均成长心态较弱的青少年相比，其日间皮质醇斜率明显更陡。研究结果指出了社会经济地位的成长心态对青少年压力相关结果的有益影响，以及在探索这些关联时考虑父母和青少年心态的重要性。
