This paper examines the evidence base for interventions which seek to enhance social support resources for families with children at risk of adverse developmental outcomes. Substantive and methodological issues related to the implementation of social support interventions are discussed and a research agenda for the development, testing and evaluation of such interventions is presented. 相似文献

Sexual minority adolescents (SMA) report more suicide risk behaviors than heterosexual adolescents. Polyvictimization (co‐occurrence of multiple types of victimization) may be an important, underresearched correlate of this disparity. With the 2017 national Youth Risk Behavior Survey (N = 13,179), national estimates of polyvictimization and suicide risk were assessed among high school students by sexual minority status (SM vs. heterosexual), and multivariate relationships between sexual minority status, polyvictimization, and suicide risk were tested. Additionally, risk profiles of those who experienced polyvictimization (2 + types of victimization; n = 1,932) were compared across sexual minority status. Results confirm that SMA are more likely to experience polyvictimization than heterosexual adolescents (31.8% v. 12.9%, respectively); however, also indicate that polyvictimization does not fully explain elevated suicide risk among SMA. 相似文献

The main goal of this study was to more closely understand the direction of relations between maternal behavior and young children's defiance and committed compliance. We examined 256 mother–child dyads to explore developmental transactional relations between maternal assertive control, children's committed compliance, and children's defiance at 18 (T1), 30 (T2), and 42 (T3) months of age. After controlling for maternal gentle control, SES, and child sex, results showed parent effects for children's committed compliance, such that T1 maternal assertive control negatively predicted T3 committed compliance. Furthermore, toddlers’ behavior predicted T3 parenting; that is, toddlers’ T1 defiance positively predicted T3 maternal assertive control. Results of the present study indicate relatively long-term prediction (to 42 months) from both parent and child behaviors at 18 months of age, and the findings have implications for understanding the bidirectional and complex processes that account for young children's adaptive and maladaptive behaviors. 相似文献

The problems of estimation and hypotheses testing on the parameters of two correlated linear models are discussed. Such models are known to have direct applications in epidemiologic research, particularly in the field of family studies. When the data are unbalanced, the maximum-likelihood estimation of the parameters is achieved by adopting a fairly simple numerical algorithm. The asymptotic variances and covariances of the estimators are derived, and the procedures are illustrated on arterial-blood-pressure data from the literature. 相似文献

Mangat and Singh (1990) have suggested a two stage randomized response technique to estimate the proportion of population possessing a sensitive attribute. The procedure was shown to be more efficient than the procedure due to Warner (1965). Recently, Tracy and Osahan (1993) have suggested a modification to the Mangat and Singh (1990) procedure which results in a more efficient strategy in practice. In this paper we propose a modification to the Tracy and Osahan (1993) procedure. The modified procedure is a generalization of Tracy and Osahan (1993) and is always more efficient than their strategy. An empirical study has also been undertaken to find the extent of relative efficiency. 相似文献

We consider the probability-weighted moment and the maximum-likelihood estimators of two parameters in the log-logistic distribution. Quantile estimators are obtained using both methods. The distributional properties of these estimators are studied in large samples, via asymptotic theory, and in small and moderate samples, via Monte Carlo simulation. The distribution is shown to be appropriate for a wide variety of meteorological data. 相似文献

By focusing on formal intensive interview research, this essay explores how the sociohistorical context influences the routine
procedures by which sociologists obtained permission to conduct their studies. We examine the permissions process within the
specific historical context of the 1950s and contrast it with contemporary issues of informed consent. The need for a more
theoretical and situational understanding of permissions is identified, both in regard to human—subjects regulations and social
control.

Parents receive social work services (both voluntary and involuntary) in a variety of settings. Although the parents may have come to need social work interventions for different reasons, one reason is constant: They are experiencing some difficulty with their children. Children are likely to benefit when parenting ability is strengthened. In all settings, social workers have a unique opportunity to assist parents in establishing, restoring, or maintaining healthy family dynamics. 相似文献

This paper models the bias from using potential vs actual experience in log wage models. The nature of the problem is best
viewed as specification error as opposed to classical errors-in-variables. We correct for the discrepancy between potential
and actual work experience and create a predicted measure of work experience. We use the 1979 National Longitudinal Survey
of Youth and the Panel Study of Income Dynamics and extend our findings to the Integrated Public Use Microdata Sample. Our
results suggest that potential experience biases the effects of schooling and the rates of return to labor market experience.
Using such a measure in earnings models underestimates the explained portion of the male–female wage gap. We are able to separately
identify the decomposition biases associated with incorrect experience measures and biased parameter estimates.
