The Roles of Parental Support and Family Stress in Adolescent Sleep.

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage  = 16.40 years, 43% male) and their parents (Mage  = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self-reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep.

Discrimination and Sleep Difficulties during Adolescence: The Mediating Roles of Loneliness and Perceived Stress.

Irregular and insufficient sleep place youth at risk for adverse psychological and physical health outcomes. Recent research indicates that discrimination constitutes a type of stressor that interferes with adolescent sleep; however, the mechanisms through which discrimination affects sleep are not well understood. This study examined whether ethnic and non-ethnic (i.e., gender, age, and height/weight) discrimination were associated with adolescents' sleep duration, variability, and quality, and whether loneliness and perceived stress mediated these associations. An ethnically-diverse sample (42% Latino, 29% European American, 23% Asian) of adolescents (N = 316; M age = 16.40 years, 57% girls) reported on their experiences of discrimination, perceived stress, and loneliness. Sleep duration and variability were assessed by actigraphy and sleep quality through self-reports. Ethnic discrimination was related to shorter sleep duration and both ethnic and non-ethnic discrimination were associated with worse sleep quality. Loneliness and perceived stress partially mediated the relation between discrimination and sleep quality. Discriminatory experiences can heighten feelings of loneliness and stress, which, in turn, may contribute to diminished sleep quality during adolescence.

Sleep and Inflammation During Adolescence.

OBJECTIVE: To investigate the associations between objective and subjective dimensions of adolescent sleep and C-reactive protein (CRP), a key biomarker of inflammation that predicts chronic health problems in adulthood, and whether the associations vary as a function of adolescents' age. METHODS: A total of 315 adolescents (14.5-18.4 years) wore wrist actigraphs at night to objectively estimate their sleep duration and variability across nights, and completed the Pittsburgh Sleep Quality Index to assess their subjective sleep quality. CRP levels were assayed from dried blood spots obtained from finger pricks. To control for adiposity, age- and sex-specific body mass index percentiles were obtained from height and weight measurements. RESULTS: Nightly variability in sleep duration was associated with higher levels of CRP (b = 0.13, p = .045). Shorter average sleep duration was associated with higher CRP, but only among younger adolescents (b = -0.11, p = .041). Subjective sleep quality was not associated with CRP. CONCLUSIONS: The association of sleep with inflammation during adolescence seems more evident in objective dimensions of sleep duration and variability than in the subjective dimensions of sleep quality. Insufficient sleep may be particularly consequential for younger adolescents.

Developmental flexibility in the age of globalization: autonomy and identity development among immigrant adolescents.

The socioeconomic and cultural changes that result from an increasingly interconnected world have been speculated to have important implications for the nature of adolescent development. Unfortunately, the historical time necessary for these changes to take place means that definitive research on the impact of globalization necessarily will be slow in forthcoming. Adolescents from immigrant families, however, already experience the social and cultural shifts thought to typify globalization, and an analysis of their experiences could shed light on what to expect as existing national barriers become more permeable. The value of flexibility in the face of great social and cultural change appears to be the dominant theme from research on immigrant youth, although that flexibility can be constrained by socioeconomic, ethnic, and racial stratification systems in host societies. This review highlights the implications of these findings for what may lie ahead for teenagers as globalization continues to expand.

Mexican American Adolescents' Emotional Support to the Family in Response to Parental Stress.

In this two-wave longitudinal, daily diary study that followed up with 421 Mexican American parent-adolescent dyads (adolescents: Mage = 15 years, 50% males) after 1 year, we investigated the contingency between parental stressors and adolescents' emotional support to family members. Adolescents provided support to their parents and other family members at similar rates, but adolescents were more likely to provide support to other family members than to their parents on days when parents experienced a family stressor. This pattern was especially pronounced in families with parents who reported physical symptoms and adolescents with a strong sense of family obligation. Adolescents' provision of emotional support was associated with same-day feelings of role fulfillment, but not to their concurrent or long-term psychological distress.

Parental Cultural Socialization of Mexican-American Adolescents' Family Obligation Values and Behaviors.

The current study examined how parents' cultural socialization efforts contribute to adolescents' family obligation values and behaviors and how these processes may depend upon the relational climate at home. Utilizing survey and daily diary methodologies, 428 Mexican-American adolescents (50% males; Mage  = 15 years) and their parents (83% mothers; Mage  = 42 years) participated in the study. Adolescents reported on their family obligation values and engagement in family assistance tasks across 14 days. Parents reported on their cultural socialization practices. Results indicated that parental cultural socialization was associated with adolescents' family obligation values and behaviors when parent-child relationships were low in conflict and high in support. Findings suggest that the transmission of cultural values and practices is best facilitated through positive parent-child relationships.

Changes in Religiosity Across the Transition to Young Adulthood.

Social identities, as those pertaining to religion, may change over time as adolescents make the important transition into young adulthood. This 4-year longitudinal study examined developmental changes in religious affiliation, identity, and participation across the transition from adolescence to young adulthood among 584 individuals (from M age  = 17.9 years to M age  = 22.1 years; 55 % female). We also investigated whether changes varied as a function of individual (i.e., gender and ethnicity) and contextual (i.e., college type and residential status) factors, as well as the association between religiosity and well-being (e.g., meaning and purpose in life, depressive symptoms). The results indicated a significant decline in reported affiliation with a particular religious group or faith for all youth. The change in a psychological sense of religious identity varied by gender, and the change in religious participation differed by ethnicity, but other individual-difference factors generally played minor roles in the changes in religiosity across time. Religiosity was more consistently linked with a greater sense of meaning and purpose than with fewer depressive symptoms across the transition to adulthood, suggesting that it may be particularly important for eudaimonic well-being. Overall, the findings suggest that youth generally experience a decrease in religiosity as they transition to young adulthood, but this rate of change may vary between individuals. The results have important implications for the way in which religion is viewed and lived out by young adults in the United States.

Continuity and discontinuity in perceptions of family relationships from adolescence to young adulthood.

The present 8-year longitudinal study examined how multiple aspects of family relationships change across the transition from adolescence (Mage  = 15 years) to young adulthood (Mage  = 22 years) among 821 individuals. Results showed that there was more discontinuity than continuity in family relationships across this transition. Whereas a normative decline was evident in all measured aspects of family relationships during adolescence, this decline persisted for only a few dimensions of family relationships during young adulthood. Other aspects of family relationships stabilized or rebounded. There was little variation in these trajectories as a function of ethnicity or gender, suggesting that these changes in family relationships are generally normative. Results suggest that the transition to adulthood is a period of significant transformation in family relationships.

Effects of Family Obligation Values and Autonomy Support on Internalizing Symptoms of Vietnamese-American and European-American Adolescents.

Objectives: Although negotiation of family relatedness and personal autonomy is a key developmental task of adolescence, what is most adaptive for adolescents may vary across cultures. The purpose of the present study was to examine whether relations between family obligation values and adolescent internalizing symptoms may vary as a function of the level of parental autonomy support perceived by the adolescent, and to assess the extent to which such associations vary by ethnic group. Methods: The study included 614 adolescents (Mean age = 15.57 years, 50% male) from Vietnamese-American (55%) and European-American (45%) backgrounds. Adolescents reported their: (a) family obligation values to (a1) respect, (a2) provide current assistance, and (a3) provide future support to the family, (b) perceived maternal and paternal autonomy support, and (c) internalizing symptoms. Results: Effects of family obligation values differed across the three subdomains as a function of maternal autonomy support and ethnic group. Family obligation values to respect the family (a1, above) were related to lower levels of internalizing symptoms for both Vietnamese- and European-American adolescents who received high levels of maternal autonomy support. Ethnic differences emerged such that only among Vietnamese-American adolescents, there was a negative relation between current assistance values (a2, above) and internalizing symptoms among adolescents with high maternal autonomy support. Conclusions: Overall, findings highlight the importance for parents to nurture adolescents' family obligation values while also promoting their autonomy development.

Daily family stress and HPA axis functioning during adolescence: The moderating role of sleep.

The present study examined the moderating role of sleep in the association between family demands and conflict and hypothalamic-pituitary-adrenal (HPA) axis functioning in a sample of ethnically diverse adolescents (n=316). Adolescents completed daily diary reports of family demands and conflict for 15 days, and wore actigraph watches during the first 8 nights to assess sleep. Participants also provided five saliva samples for 3 consecutive days to assess diurnal cortisol rhythms. Regression analyses indicated that sleep latency and efficiency moderated the link between family demands and the cortisol awakening response. Specifically, family demands were related to a smaller cortisol awakening response only among adolescents with longer sleep latency and lower sleep efficiency. These results suggest that certain aspects of HPA axis functioning may be sensitive to family demands primarily in the context of longer sleep latency and lower sleep efficiency.

Mexican American adolescents' family obligation values and behaviors: links to internalizing symptoms across time and context.

Family obligation is an important aspect of family relationships among families from Mexican backgrounds and can have significant implications for adolescents' well-being. Prior research and theory regarding youths' obligations offer conflicting hypotheses about whether it is detrimental or beneficial for adolescents' well-being. In the current longitudinal study, we used a daily diary method among 428 Mexican American adolescents and their parents to closely examine the impact of adolescents' family obligation values and family assistance behaviors on internalizing symptoms over time. The authors closely examined the role of the family context in these associations. Results suggest that family obligation values relate to declines in adolescents' internalizing symptoms, whereas family assistance behaviors are both a protective and risk factor, depending on the family context. Only when youths provide family assistance in response to acute changes in parental physical and psychological distress do family assistance behaviors relate to increases in adolescents' internalizing symptoms.

Daily concordance between parent and adolescent sleep habits.

PURPOSE: To assess the daily concordance between parent and adolescent daily sleep habits, how that concordance compares to other predictors of sleep, and whether the degree of concordance varies across families. METHODS: A total of 421 adolescents (Mage = 15.03 years) and their primary caregivers (Mage = 41.93 years) reported their sleep, bed, and wake times on a daily basis for a 2-week period. Approximately 80% of the sample repeated the same protocol 1 year later. RESULTS: Multilevel modeling indicated a significant concordance between parent and adolescent sleep, bed, and wake times on a daily basis. Concordance existed independent of other predictors of sleep such as day of the week and adolescent study time. Larger families and those with higher levels of parent-adolescent support exhibited greater concordance. CONCLUSIONS: Adolescent sleep is connected to the sleep habits of their parents, above and beyond commonly known structural and experiential factors that can shape teenage sleep. Efforts to improve teenage sleep should pay greater attention to the sleep patterns of parents and potentially other family members.

Adolescents' Daily Assistance to the Family in Response to Maternal Need.

Although children's provision of family assistance is a common routine, little is understood about the day-to-day variability that may exist in children's assistance behaviors. Guided by a family systems framework, the current study examined whether Mexican American adolescents' provision of family assistance was contingent on daily maternal need. Adolescents (N = 354, 49% males, Mage = 14.96 years) and their mothers (Mage = 41.55 years) each completed reports on 14 consecutive days. The results indicated that adolescents generally responded to maternal need, being more likely to help their families on days when their mothers worked or felt fatigued. This daily contingency was modified by family and adolescent characteristics, with adolescents thought to generally engage in low levels of assistance (i.e., youngest males and those in families with little economic strain) increasing their help when their mothers were fatigued. In contrast, daily maternal work did not appear to stimulate greater assistance among families with low levels of economic strain.

Change in ethnic identity across the college transition.

This article examined changes in ethnic identity as a function of college type and residential status and whether differences due to college type could be explained by involvement in extracurricular activities and college ethnic composition. Although no changes in ethnic labeling or belonging were found, there was a normative decrease in ethnic search, independent of residential status. Moreover, the decline in ethnic search was significantly greater at 2- than 4-year colleges, and this difference was mediated by higher rates of participation in extracurricular activities at 4-year colleges. Ethnic identity did not vary by college ethnic composition. There were no ethnic or generation differences in ethnic identity change; however, women were more likely to include an American term in their ethnic label than were men, over time. Averaging across time, students at 4-year colleges also had a greater preference for the American term in their ethnic labels. Findings illuminate the importance of context in shaping ethnic identity.
