Adrenocortical activity in at-risk and normally developing adolescents: individual differences in salivary cortisol basal levels, diurnal variation, and responses to social challenges.

The purpose of this study was to examine adrenocortical activity (basal, diurnal variation, and responses to social stressors) in adolescents at risk for psychopathology. Salivary cortisol levels were examined in normally developing and at-risk youth with internalizing and externalizing symptoms ranging from subclinical to clinical levels. Adolescents showed expected patterns of diurnal variation, with high early morning cortisol levels and a pattern of decline throughout the day. Females showed higher midday and late afternoon levels than males, and these patterns interacted with risk status. Internalizing problems sometimes were associated with gradual rather than steep declines in basal cortisol production. Both immediate and delayed cortisol reactivity to a social performance stressor were associated with internalizing symptoms. There was no evidence of relations between externalizing problems and underarousal of the hypothalamic-pituitary-adrenal (HPA) system. These and other results suggest that gender is an important moderating factor linking psychopathology. development, and context with HPA axis functioning in adolescence.

Predicting mothers' beliefs about preschool-aged children's social behavior: evidence for maternal attitudes moderating child effects.

Maternal beliefs about children's social behavior may be important contributors to socialization and development, but little is known about how such beliefs form. Transactional models suggest that children's characteristics may influence parents. At 2 years of age, the shy and aggressive behaviors of 65 toddlers (28 females) were observed during interactions with an unfamiliar peer; as well, mothers described the extent to which they advocated protective and authoritarian childrearing attitudes. These variables were used to predict mothers emotions, attributions, parenting goals, and socialization strategies in response to vignettes depicting aggressive and withdrawn child behaviors 2 years later. Most child effects were moderated by maternal attitudes or gender effects. Authoritarian mothers of aggressive toddlers were most likely to report high control and anger, to blame their children for aggression, and to focus on obtaining compliance rather than teaching skills to their children. Protective mothers reported that they would use warmth and involvement to comfort withdrawn children, especially their daughters.

Child-rearing attitudes and behavioral inhibition in Chinese and Canadian toddlers: a cross-cultural study.

Behavioral inhibition data were collected from samples of 2-year-olds from the People's Republic of China and Canada. Information on child-rearing attitudes and beliefs was obtained from mothers of the children. Chinese toddlers were significantly more inhibited than their Canadian counterparts. Inhibition was associated positively with mothers' punishment orientation and negatively with mothers' acceptance and encouragement of achievement in the Canadian sample. However, the directions of the relations were opposite in the Chinese sample; child inhibition was associated positively with mothers' warm and accepting attitudes and negatively with rejection and punishment orientation. The results indicated different adaptational meanings of behavioral inhibition across cultures.

Parenting goals as organizers of responses to parent-child disagreement.

Parenting goals are outcomes that parents hope to achieve during interactions with children. Three studies involving 138 men (78 fathers) and 158 women (110 mothers) examined the causes and consequences of parents' focusing on various goals during disagreements with young children. Women were more likely than men to focus on relationship-centered (RC) goals, public situations increased concern for short-term parent-centered (PC) goals, and empathy was predictive of long-term child-centered (CC) and RC goals. PC goals were associated with power assertion, CC goals with reasoning, and RC goals with warm, negotiating, and cooperative parenting behavior. Attributions of intentionality and dispositional causation were possible mediators of the link between power assertion and PC and CC goals. Instructions to focus on PC goals increased negative affective states and decreased sympathy for children, whereas instructions to focus on RC goals had the opposite effects.

The consistency and concomitants of inhibition: some of the children, all of the time.

Toddlers displaying extremely inhibited behavior may be at risk for becoming socially withdrawn. However, behavioral inhibition may be a multifaceted characteristic, and its concurrent relation to toddler wariness with peers has not been examined. In this study, 108 toddlers (54 females) and their mothers were observed in novel situations involving unfamiliar settings, adults, and peers. Vagal tone, temperament, separation-reunion behavior, and maternal oversolicitousness also were assessed. There was little consistency of inhibited behavior across the 3 situations. Consistently inhibited toddlers had fearful temperaments, showed distress following maternal separation, and had mothers who were warm and controlling but unresponsive to children's cues during interaction. Toddlers with highly fearful temperaments and highly oversolicitous mothers were the most inhibited across contexts.
