ABSTRACT

PURPOSE: This study examined links between diurnal patterns of the stress hormone cortisol and time spent by adolescents in nine common daily activities. METHODS: During eight consecutive nightly telephone interviews, 28 youths (n = 12 girls), 10-18 years of age, reported their daily activities. On 4 days, four saliva samples were also collected and assayed for cortisol. Multilevel models assessed within- and between-person associations between time in each activity and cortisol area under the curve (AUC), cortisol awakening response (CAR), morning peak (30 minutes after wake up), and daily decline (morning peak to bedtime). RESULTS: Links with AUC were found for most activities; significant associations with cortisol rhythms suggested that most effects were due to anticipation of the day's activities. Specifically, on days when youths spent more time than usual on video games and television, they had lower AUCs, with lower morning peaks. Youths who spent more time reading (within-person) and in computer-related activities (between-person) had higher AUCs, with stronger CARs (within-person). Youths who slept more had lower AUCs, with lower morning peaks on both the between- and within-person levels. Amounts of time spent in clubs, and for older adolescents in sports, were also linked to lower AUCs. Finally, youths who spent more time in school/schoolwork had lower average AUCs, but on days when youths spent more time than usual in school, they had higher AUCs, stronger CARs, and steeper daily declines. CONCLUSION: Beyond their known implications for psychological adjustment, youths' everyday activities are linked to stress physiology.

ABSTRACT

Using data from a daily diary study of hourly hotel employees in the U.S. and their children, this study examined links between youth supervision arrangements and maternal worry while at work, examining both differences between individuals and day-to-day variation within individuals. Multilevel model analyses revealed both between- and within-person effects linking youth supervision to maternal worry. Mothers' partner status functioned as moderator, and maternal knowledge also emerged as a protective factor when youth were in self-care, highlighting a potential target for future work-family interventions, particularly those for hourly employees with limited access to family-friendly workplace policies.En utilisant les données d'une étude de journal quotidien des employés horaires de l'hôtel aux États-Unis et leurs enfants, cette étude a examiné les liens entre les modalités de supervision des jeunes et l'inquiétude maternelle pendant le travail, en examinant à la fois les différences inter individus et la variation intra individus au jour le jour. Analyses multi-niveaux ont révélé à la fois des effets inter et intra reliant la supervision des jeunes à l'inquiétude maternelle. Statut de partenaire des mères a fonctionné en tant que modérateur, et la connaissance maternelle est également apparue comme un facteur de protection lorsque les jeunes ont pris soins d'eux-mêmes, soulignant une cible potentielle pour des interventions de conciliation travail-famille, en particulier ceux conçus pour des employés horaires avec un accès limité à des politiques favorables à la famille.

ABSTRACT

We examined correlates of sources of parental knowledge of youths' experiences in Mexican American families, including child self-disclosure, parental solicitation, spouse, siblings, and individuals outside the family. Home and phone interviews were conducted with mothers, fathers, and their seventh-grade male and female offspring in 246 Mexican American families. Results indicated that mothers and fathers relied on different sources of knowledge; parent-child relationship quality and cultural orientations predicted parents' sources of knowledge; and different sources had different implications for youth adjustment. Specifically, child disclosure to mothers and fathers' reliance on their spouse were consistently linked to better youth outcomes. Moderation analyses revealed that correlates of parents' knowledge sources were not always uniform across mothers and fathers or daughters and sons.
