A community sample of 295 mothers, fathers, and children (M age = 11.14 years, SD = 2.32 years) rated marital distress, maternal and paternal psychological symptoms, and child adjustment. The predicted direct relations between these family and child variables were demonstrated for both fathers and mothers. Tests of pathways among these variables were conducted for separate but complementary mediation models. Maternal and paternal symptoms mediated the association between marital distress and child adjustment. Marital distress mediated the link between fathers’ symptoms and child adjustment, but the direct pathway between mothers’ symptoms and child adjustment remained. Pubertal status was modestly related to higher levels of family stressors. Joint implications of marital distress and parental symptoms for child adjustment are discussed.  相似文献

In the Age of Terrorism fear becomes a constant companion. This is particularly true in a society already beset by a culture of fear. We explore some cognitive effects of fear induced by victimization to explain America’s reaction to the events of 9/11. Using reliable measures of value orientations we find that exposure to violence produces a shift in value orientations toward values that are more self-enhancing. America’s seemingly fractured state may be explained in part by this effect.  相似文献

In software reliability theory many different models have been proposed and investigated. some of these models intuitively match reality better than others. The properties of certain statistical estimation procedures in connection with these models are also model-dependent. In this paper we investigate how well the maximum likelihood estimation procedure and the parametric bootstrap behave in the case of the very well-known software reliability model suggested by Jelinski and Moranda (1972). For this study we will make use of simulated data.  相似文献

An explanatory model of adolescent problem behavior (problem drinking, cigarette smoking, and general delinquency) based on protective and risk factors in the individual and in 4 social contexts (family, peer group, school, and neighborhood) is employed in school‐based samples from the People's Republic of China (N=1,739) and the United States (N=1,596). Despite lower prevalence of the problem behaviors in the Chinese sample, especially for girls, a substantial account of problem behavior is provided by the same protective and risk factors in both countries and for both genders. Protection is generally higher in the Chinese sample than in the U.S. sample, but in both samples protection also moderates the impact of risk. Despite mean differences in psychosocial protective and risk factors, as well as in problem behavior, in the 2 samples—differences that may reflect societal variation—the explanatory model has, to a large extent, cross‐national generality.  相似文献

This paper examines the socialization and adjustment experiences of newcomers to organizations from a role stress perspective. A longitudinal field study is reported which tested a three-stage socialization model using physiological and psychological distress symptoms, general satisfaction, and intention to leave the organization as indicators of newcomer adjustment. Data were collected from newcomers (the focal role) (N = 91) at three times during me study and also from their supervisors (the role senders) (N = 41). While the data confirmed the general utility of the model, it also suggested some revisions by way of new and altered pathways between some of the variables.  相似文献

Where funded by government, prevalence studies have typically led to the development of services for problem gamblers and their families. Such assessments of the need for services have been seen as the appropriate political response to growing expressions of concern about problem gambling that often follow moves to legislate for an increasing range of gambling products. This theme is apparent for Australia, Canada, New Zealand and the United States. In this paper, initiatives in these different jurisdictions are briefly summarized and tabulated.  相似文献
