Using longitudinal data collected at four time points from 191 dyads of Mexican‐origin adolescent first‐time mothers and their mother figures, we examined changes in and socialization of traditional gender role attitudes across the transition to parenthood using latent growth curve modeling and actor – partner interdependence modeling. Longitudinal growth models indicated that, regardless of nativity status, adolescent mothers' and their foreign‐born mother figures' gender role attitudes became more egalitarian across adolescents' transition to parenthood, spanning from the 3rd trimester of pregnancy to 36 months postpartum. Furthermore, actor‐partner interdependence modeling suggested that adolescents' and their mother figures' gender role attitudes during adolescents' third trimester of pregnancy equally contributed to subsequent increases in one another's gender role attitudes at 10 months postpartum. Importantly, this reciprocal socialization process was not moderated by adolescent mothers' nor by their mother figures' nativity status. Findings suggest that it is important to understand the cultural and intergenerational family processes that contribute to the development of gender role attitudes during the transition to parenthood for adolescent mothers and their mother figures in Mexican‐origin families.  相似文献

Although a range of methods allow investigators to measure the local dependencies among behaviors in a sequence, only indirect methods are available for measuring the interrelationships among behaviors across an entire sequence. This article introduces a new “proximity” coefficient that measures interrelationships among behaviors as a direct function of their intrinsic organization within a sequence. The coefficient does not depend on a user-defined “window” of analysis and provides an efficient use of data that facilitates comparisons across actors, over time periods, and between single cases. An analysis of artificial data shows further properties of the coefficient, including a diagonal value that reflects the degree to which a behavior is reciprocated, and an asymmetry in values that depicts the relative precedence among behaviors. Extensions of the coefficient to the multivariate case, and its relation to existing methods of analyzing sequences, are discussed.  相似文献

Informed consent, decision-making styles and the role of patient-physician relationships are imperative aspects of clinical medicine worldwide. We present the case of a 74-year-old woman afflicted with advanced liver cancer whose attending physician, per request of the family, did not inform her of her true diagnosis. In our analysis, we explore the differences in informed-consent styles between patients who hold an "independent" and "interdependent" construal of the self and then highlight the possible implications maintained by this position in the context of international clinical ethics. Finally, we discuss the need to reassess informed-consent styles suitable to the needs of each patient regardless of whether he or she resides in the United States or in Japan.  相似文献

Cognitive models of obsessive-compulsive disorder (OCD) posit that specific kinds of dysfunctional beliefs (e.g., pertaining to responsibility and the significance of intrusive thoughts) underlie the development of this disorder. The present study was designed to prospectively evaluate whether dysfunctional beliefs thought to underlie OCD act as a specific vulnerability factor in the pathogenesis of obsessive-compulsive symptomatology. Eighty-five individuals were prospectively followed over a period of time thought to be associated with an increased onset of OCD symptoms -- childbirth and the postpartum. The majority of these new mothers and fathers experienced intrusive infant-related thoughts and performed neutralizing behaviors similar to, but less severe than, those observed in OCD. Scores on a measure of dysfunctional beliefs thought to underlie OCD predicted the development of obsessive-compulsive symptoms after controlling for pre-existing OCD symptoms, anxiety, and depression. Dysfunctional beliefs also predicted the severity of checking, washing, and obsessional OCD symptom dimensions, but not neutralizing, ordering, or hoarding symptom dimensions. These data provide evidence for specific dysfunctional beliefs as risk factors in the development of some types of OCD symptoms.  相似文献

The well-documented relation between the phenotypes of low IQ and childhood antisocial behavior could be explained by either common genetic influences or environmental influences. These competing explanations were examined through use of the Environmental Risk Longitudinal Twin Study 1994-1995 cohort (Moffitt & the E-Risk Study Team, 2002) of 1,116 twin pairs and their families. Children's IQ was assessed via individual testing at age 5 years. Mothers and teachers reported on children's antisocial behavior at ages 5 and 7 years. Low IQ was related to antisocial behavior at age 5 years and predicted relatively higher antisocial behavior scores at age 7 years when antisocial behavior at age 5 years was controlled. This association was significantly stronger among boys than among girls. Genetic influences common to both phenotypes explained 100% of the low IQ-antisocial behavior relation in boys. Findings suggest that specific candidate genes and neurobiological processes should be tested in relation to both phenotypes.  相似文献

Patients with schizophrenia have a substantial lifetime suicide risk, especially by violent means. Little published work exists on self-harm (SH) in this population. The goal of this study was to examine whether patients with schizophrenia were also more likely to self-harm in a violent manner. A retrospective analysis performed on method, motive, and suicidal intent in patients with schizophrenia (n = 50) and adjustment reaction (n = 138) who presented with SH over a 3-year period found that there was no significant difference between the two groups in terms of violence of method or suicidal intent. Presence of positive symptoms of schizophrenia was not significantly associated with use of a violent method. This study suggests that the expected pattern of violent SH in schizophrenia is inaccurate and for the majority the acts are of a similar nature to those seen in adjustment reactions.  相似文献
