BackgroundThis study investigated the potential environmental effects of peer victimization and the quality of relationships with parents and friends on diurnal cortisol secretion in mid-adolescence.MethodThis study used the monozygotic (MZ) twin-difference design to control for genetic effects and thus estimate the unique environmental influences on diurnal cortisol. Participants were 136 MZ twin pairs (74 female pairs) for whom cortisol was assessed four times per day over four collection days grouped in a 2-week period in grade 8 (mean age = 14.07 years). Participants also provided self-reports of peer victimization from grade 4 to grade 8 and of the relationship quality with the mother, father and best friend in grade 8.ResultsThe expected pattern of diurnal cortisol secretion was observed, with high levels at awakening followed by an increase 30 min later and a progressive decrease subsequently. Controlling for a host of confounders, only within-twin pair differences in peer victimization and a problematic relationship with the mother were significantly linked to twin differences in diurnal cortisol secretion. Specifically, whereas a more problematic mother–child relationship was associated with morning cortisol secretion, peer victimization was linked to cortisol secretion later in the day (diurnal slope).ConclusionsControlling for genetic influences and other confounders, stressful relationships with peers and the mother exert unique and time-specific environmental influences on the pattern of diurnal cortisol secretion in mid-adolescence.

Associations between family functioning and children's stress hormone levels are explored, by examining how aspects of the interparental relationship (parents' marital satisfaction and parent conflict styles), the mother—child relationship (maternal involvement and warmth) and maternal emotional functioning (depression, anxiety and self-esteem) relate to children's cortisol levels. Parents of 63 children (32 kindergarten-aged children, 31 adolescents) completed questionnaires regarding family and individual functioning, and children's salivary cortisol samples were collected on two consecutive weekdays at home immediately upon waking and at bedtime, such that wakeup, bedtime and average levels and the slope of their diurnal cortisol rhythms could be estimated. Higher marital functioning was significantly and independently associated with lower child cortisol levels (average levels and wakeup levels), while maternal parenting quality and emotional functioning were not significant when included in the same regression model. Associations between parents' marital functioning and children's bedtime cortisol levels and diurnal slopes were moderated by child age, with higher parent marital functioning being associated with a significantly greater lowering of bedtime levels and steeper diurnal slopes for kindergarten-aged children as compared to adolescents. Higher maternal parenting quality was found to be significantly related to steeper diurnal cortisol rhythms.

This article analyses the evolution of the mother–daughter relationship in China, and describes the mothering characteristics of four generations of women, which in sequence includes “foot-binding mothers”, “mothers after liberation”, “mothers after reform and opening up”, and “mothers who were only daughters”. Referring to Klein’s ideas about the mother–child relationship, especially those in her paper “Some reflections on ‘The Oresteia’ ”, the author tries to understand mothers and their impact on their daughters in these various periods of Chinese history, so as to explore the mutual influence of the mother–daughter relationship in particular, and the Chinese cultural and developmental context in general.
