We studied young adolescents' seeking out support to understand conflict with their co‐resident fathers/stepfathers, and the cognitive and affective implications of such support‐seeking, phenomena we call guided cognitive reframing. Our sample included 392 adolescents (Mage = 12.5, 52.3% female) who were either of Mexican or European ancestry and lived with their biological mothers and either a stepfather or a biological father. More frequent reframing was associated with more adaptive cognitive explanations for father/stepfather behavior. Cognitions explained the link between seeking out and feelings about the father/stepfather and self. Feelings about the self were more strongly linked to depressive symptoms than cognitions. We discuss the implications for future research on social support, coping, guided cognitive reframing, and father–child relationships.  相似文献

Gaze is one of the main means of communication in young infants, and it has been shown to be important for subsequent socio‐emotional and cognitive development. Maternal depression is a well‐known risk factor for disrupting mother–infant interactions, but findings regarding gaze behavior in infants of depressed versus nondepressed mothers have been ambiguous. In this study, we examined gaze duration and activity in a sample of 27 infants of mothers with postpartum depression (PPD) and 49 infants of nondepressed mothers. Maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale, and diagnoses were confirmed in clinical interview. Infant gaze was assessed during 4‐month face‐to‐face interactions using continuous timed‐event coding with high temporal resolution. Although we found no differences in gaze duration, infants of PPD mothers had both significantly less Gaze On and also less Gaze Off events. Findings suggest that PPD is related to reduced gaze activity during mother–infant interaction in 4‐month‐olds. This reduced activity may have long‐term negative consequences for child development.  相似文献

Scholars across many disciplines have amassed a mountain of research documenting how social differences along lines of race, class, gender, and sexuality shape how those who need medical attention are cared for in the US healthcare system. Here, we aim to succinctly review a selection of studies that have considered the many ways both patients' and healthcare providers' social identities can impact care delivery. After establishing how these differences influence patient–provider interactions and patient diagnosis, treatment, and outcomes, we argue that a critical sociological perspective can help us to better understand why these inequities persist despite decades of research calling attention to them. Specifically, we suggest that research guided by symbolic interactionist and intersectional frameworks can generate more comprehensive analyses of inequality in healthcare delivery and help researchers delve deeper into the complex interactional processes undergirding disparities in care provision. We conclude by highlighting recent work that illustrates the value of this approach.  相似文献

The number of subjects in a pharmacokinetic two‐period two‐treatment crossover bioequivalence study is typically small, most often less than 60. The most common approach to testing for bioequivalence is the two one‐sided tests procedure. No explicit mathematical formula for the power function in the context of the two one‐sided tests procedure exists in the statistical literature, although the exact power based on Owen's special case of bivariate noncentral t‐distribution has been tabulated and graphed. Several approximations have previously been published for the probability of rejection in the two one‐sided tests procedure for crossover bioequivalence studies. These approximations and associated sample size formulas are reviewed in this article and compared for various parameter combinations with exact power formulas derived here, which are computed analytically as univariate integrals and which have been validated by Monte Carlo simulations. The exact formulas for power and sample size are shown to improve markedly in realistic parameter settings over the previous approximations. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

The article presents a case study of an outpatient mental health clinic serving Latino older adults. The study explored staff perceptions on the clinic development and the context within an immigrant multicultural community. The study used in-depth, semistructured interviews with support staff, clinical social workers, and administrators. Interviews were analyzed using a thematic content analysis. The mental health clinic formation was perceived by staff as an ecological process stemming from the needs of the Latino immigrant senior clients. A close knit and interdependent culture allowed the clinic to adjust to diversity and changing cultural contexts.  相似文献

Although cross-cultural research concerning children's emotions is growing, few studies have examined emotion dysregulation in culturally diverse populations. This study compared 6- to 8-year-old children's reported methods of expressing and controlling anger, sadness, and physical pain, and their justifications for doing so across four groups in urban India: those with internalizing problems (N = 31), externalizing problems (N = 32), somatic complaints (N = 25), and an asymptomatic control group (N = 32). Results revealed that in comparison to physical pain, Indian children were less likely to report expressing anger and sadness through direct facial/verbal means. Control-group children reported expressing anger and sadness through indirect verbal cues more so than pain, whereas the internalizing and externalizing groups considered their expressions of anger and sadness uncontrollable and reported crying and utilizing aggressive behaviors, respectively, more than the control group. The somatic complaints group considered emotions trivial and reported withdrawing more than the control group.  相似文献
